3 I - INTRODUCTION In the last years of the 20th century a major world concern unites different research groups, social segments and governments - conservation of the tropical forests, meeting the requirements of the human population and the necessary economic growth. The initial outcome of this concern today is the notion that only by adopting a sustainable development project integrating technique and social improvement will it be possible to conserve natural resources, tropical forests all over the world and improve the quality of life for the human race. Historically, the countries where the nature-society bionomial has high levels of degradation lie exactly in the inter-tropical areas, between latitudes 23 North and 23 South. Their histories demonstrate a sad relationship between colonization, exploitation of their natural resources, population growth, demographic implosion of autochthonous groups, method of production, technology and social exclusion. The consequences of this relationship, considered today to be unsustainable, are the increase in geometric progression of the processes linked to incorporating land into the prevailing productive methods, always beginning at the deforestation stage; deteriorating living conditions in the rural and urban environment; and loss of autochthonous cultural roots. In this sphere, the Amazon domain has been recognized as a matter of worldwide concern regarding its progressive natural and social deterioration and its potential and importance in maintaining the biosphere-atmosphere balance. The Amazon, stretching across nine countries, Brazil, Colombia, Peru, Venezuela, Ecuador, Bolivia, French Guinea, Surinam and Guyana, comprises a total area of around 7.8 million km 2, 70% of which is in Brazilian territory, representing more than 60% (around 5.5 million km 2 ) of this country. It is defined in Brazil, for political-administrative purposes, as the Legal Amazon, consisting of the states of Acre, Amazonas, Roraima, Pará, Mato Grosso, Amapá, Tocantins and most of western Maranhão (Fig.1) II - GENERAL ECOLOGY In terms of river drainage, the Amazon region covers the Solimões-Amazon, Tocantins river basins and part of the Orinoco river basin. The 6,577 km long Amazon river is considered today the longest river with the largest volume of water in the world. It is the area with prevailing plant formations of tropical rain forests and savanna vegetation. Alongside this apparent unity in terms of river drainage, a range of complex ecosystems have developed with different characteristics of relief, soil, flora, fauna and morpho-dynamic processes. In order to understand these different landscapes, it is necessary to go back to the history of the Amazon basin s physical geography and its beginning when the Andes mountain range emerged around 68 million years ago (Cenozoic Era). This new mountain range inverted the previous drainage pattern, creating today s vast depression between the arch at the foot of the Andes mountains, the Guyana and Brazilian plateaus, and is considered one of the largest inland lowland amphi- 279
4 theaters on Earth. Fluvial-lacustrine deposits prevailed for some time in this depression. Another slight uplift sloping generally eastwards determined the Amazon river and its western tributaries. In this sense, then, the Amazon is a geologically young river. Today the relief system consists of a broad amphitheater opening eastwards and limited in the West by the Andes, by the Guyana plateau in the North and Brazilian plateau in the South. This physiography and its latitudinal position, cut by the Equator - influenced the prevailing warm rain-carrying winds blowing from the East to eventually give rise to a hot wet climate which permitted the development of the current climatic conditions. Moreover, numerous recent studies show that the continuing prevailing climatic conditions and ecological dynamic balance itself are determined partly by the existing forest. This fact confirms the hypothesis that over time, under the prevailing hydrological conditions, plant-animal interactions gradually changed the conditions of climatic behavior until the present. From the paleoclimatic viewpoint, the many studies performed on the Cenozoic in Brazil have shown that the evolution and development of the relief systems existing today resulted from the recurrence of the alternating dry and wet climates. An increase in and better distribution of the rainfall, predominance of chemical alteration of the rocks, soil formation, spread of forest vegetation and development of the river basins were associated with the rainy eras. In the river basins erosion was under control, and only occurred in a linear fashion. These were the times when biological life developed and diversified. On the other hand, a decrease in and concentration of rainfall were associated with the dry eras, which reflected immediately on the forest vegetative cover that tended to diminish in favor of the expansion of open vegetation (grassland, steppe, savanna, scrub land). The outcome is the removal of soil by the action of rainwater and filling up of valley bottoms, obstructing the flow of the rivers, since the increase in debris was much higher than the capacity of the rivers to carry it. During these dry seasons, slope erosion processes prevailed, ranging from surface run-off to mass movement, increased rates in the mechanical alteration of rocks, a drop in the river water volume and widening of the river beds. These are the times when biological life diminished and the general degradation of the landscape increased. The many studies already performed to define the role of the alternating climates have revealed the occurrence of considerable paleo-hydrological fluctuations on a regional basis, between 21,000 and 12,500 years ago, and around 7,520 years ago, when dry or semi-arid climatic conditions prevailed. In the studies on the Legal Amazon carried out by Brazilian Geography and Statistics Institute (IBGE and FBDS,1994) the mapping of natural landscape systems on a scale of 1:2,500,000 revealed this complexity, and 104 systems and 224 subsystems of natural landscapes were identified. These studies showed the importance of the presence of dichotomic natural landscapes (that is, in imbalance) between the hydrological and flora and fauna behavior, considered overall as tropical, and the abiotic landscape (relief, soils) with characteristics that differ from those of today. Such a fact confirms the hypothesis that the wet tropical conditions for the Amazon were recent and calls attention to the recentness and fragility of its biodiversity and, thereby, its ecosystems. 280
5 III - POPULATION GROWTH On the other hand, the same Brazilian Amazon today has a population of over 20 million inhabitants, representing around 15% of the whole Brazilian population, of which around 55% live in urban centers. The remaining indigenous societies total approximately 100,000 inhabitants. The regional society is formed by Indians, mestizos, small farmers, homeless groups, urban workers, large and small landowners, traditional and modern entrepreneurs. Most of these social players comprise the groups of immigrants who at different times moved there, adding to the diversity which is so characteristic of this area. This no longer includes merely its physical-natural and biological diversity but also the diversity of the social, economic and cultural colonization. In short, the change in the ecological and cultural mosaic of the Brazilian Amazon may be considered the result of four landmarks: the Portuguese spread in the 17th century; the Marquis of Pombal s policy in the 18th century; the rubber boom in the 19th/20th centuries; and the developmentalist policy of the second half of the 20th century. The 1990s, however, seem to bring with them a new referential regarding the role of this region, caused by global economic and political changes. A new phase appears now with reference to the scientific-technological revolution, environmental crisis and social movements. Meanwhile, countless projects for organizing and integrating this geographical area have been proposed and implemented. The sixties, however, may be considered the major landmark that was the basis for the changes which caused the most dramatic ecological and cultural transformations. In the early years of that decade the population was 2.6 million and by the end of the eighties had reached around 17 million (figure 2). As a result of these changes, for the period between 1960 and 1991, in demographic terms, there was an increase in the population of 14 million inhabitants, which means a total growth rate of 550%. In terms of vegetative cover, taking into consideration the forest and non-forest vegetation, in 1991 a total of 14.07% of Brazilian Amazon territory was impacted and/or deforested (Ferreira, 1996). To discuss this incorporation and humanization of the Amazon area entails discussing the different stages of devastation undergone by this region during its occupation. This expropriation of man and nature, mostly a result of the idea of the great frontier of resources, when it acquired gigantic proportions, caused the idea that there were inexhaustible resources and almost an obligation to exploit them. On the other hand, the demographic void slogan transmitted the idea of the need to occupy an area of continental dimensions. And so this region began to be compulsively colonized, on a three-pronged basis of the need for progress, search for national and international integration, and economic growth. IV - LAND TRANSFORMATION. These are transforming agents generated most frequently in areas outside the Amazon and the continent. The extent of these forces creates demands that can exert so 281
6 much pressure on the social groups living there that they become local agents of the devastation In fact, this progressive devastation, educational and cruel at the same time, is responsible for different external and internal demands for raw materials and inputs necessary for the prevailing form of production, as well as the need to solve social issues in different regions beyond the Amazon (Northeast, Mid-West and South). The answer lies in the penetration and consolidation of the control of the territory, gradual privatization of land, mines and forests and the economic and political organization of the region. THE FIRST CHANGES. Since the arrival of the indigenous nations in the Amazon, at an unknown date, until the decline in the rubber boom at the end of the 1940s, anthropic changes had little effect on the landscape. The demand for food (pirarucu, manatee), oil for lighting (manatee oil for candles and turtle oil), leather, skins and feathers for the fashion industry (alligators, monkeys, wild cats, egrets and other colored birds) and aromatic woods for perfumery (rosewood and cinnamon), was responsible for the extermination of large contingents of regional fauna and flora. Even today the pirarucu, manatee and turtles are still being destroyed and their populations have diminished greatly. The loss of biodiversity in the region can be followed throughout its history. The first devastation was that of the gallery forest along the navigable river routes. The intent was to find drugs from the sertão (inland) (cinnamon, clove, indigo, cacao, aromatic roots, oleaginous seeds, timber, sarsaparilla, etc.) used in food, seasoning, shipbuilding and the pharmacopoeia of western Europe of the 17th and 18th centuries, as well as to expand Portuguese territory. Settlements were based on the military and colonial centers and religious missions (São Gabriel da Cachoeira, Barcelos, Tefé, Santarém, etc.). Market pressures and potential led to the metropolis tentatively starting a move from collecting to cultivating these drugs. The need for manpower forced the settlers, mainly from Maranhão, to capture Indians as a labor source. The clash between the Jesuits who defended the Indians and the Maranhão settlers who produced sugar, tobacco and other products caused a further move inland by the settlers who discovered new potential products, that is, spices. This period is called the inland drug boom. In the 17th century an enormous quantity of smoked or salted manatee meat or mixira (preserve of young manatee in its own oil) was sent to Europe. Every year more than 20 vessels laden with manatee meat sailed from the port of Gurupá. By the 18th century it was hard enough to fill even one vessel with this cargo. Veríssimo, who was an encyclopedia of knowledge on Amazon matters, in 1895 spoke of the disappearance of the turtle and manatee populations from Marajó bay and the lower Tocantins. Between 1885 and 1893 the average pirarucu fish production was 1,283 tons, corresponding to 2,500 tons of fresh fish. Between 1933 and 1936, at the same port, the average annual production of dried pirarucu was 563 tons, that is, around 1,130 tons of fresh fish. These depleted resources in the 19th century were caused by the food requirements of the contingent of rubber soldiers who were the work force on the rubber plantations. 282
7 The second major devastation occurred between the last decades of last century and the first two of this century as a result of two major demands: Europe and the United States demanded a massive volume of rubber to manufacture domestic appliances, tires, war material and for shipbuilding; and the other was the need to solve problems in the Northeast due to the prolonged drought between 1877 and This was the time when Southwest Amazon was invaded and integrated, and from this period dates the incorporation of what is today the state of Acre. This was the rubber boom. The association of these national and international external demands caused a substantial increase in the number of the local population. The human contingent increased from 127,000 in 1823 to approximately 1.4 million inhabitants around They were additions to the lines of workers who spread out over those areas of thick rain forest, which has the largest occurrence of Hevea brasiliense (rubber tree). Of these areas, Acre had the largest influx of immigrants. The 1920s and 1930s saw the start of the invasion of the cattle raising and mining forerunners who penetrated through the wide gaps left by the rubber and nut extractivist organizations. The latter activities satisfied predominantly local and regional demands, resulting from the need to attend a local consumer market then and to complement the resources of those who lived on subsistence and/or plant extractivist farming. During the rubber boom, biodiversity was endangered by hunting for the rubber tappers food. As most of the work force was busy with latex extractivism, there were few extensively cleared areas in the western Amazon for farming. Most farm products were imported from other regions. Although the cropland frontiers had existed for a long time in the Amazon, they had the boundary of the forest against farther penetration. The whole rural spread ascertained until then occurred in areas of savanna and cropland. This farming activity put little pressure on the Amazon forest area until the 1960s because of its characteristics of expansion on natural pastureland and its secondary role, which demanded little in terms of the number of workers. DECADES OF DEVASTATION S. But the arrival of the 1970s inverted this situation. From that moment, the discovery of mineral wealth and poverty of the soils made these two frontiers responsible for a new boom in changing this ecological mosaic. The opening up of the Belém-Brasilia highway in the 1960s formed a North-South axis joined by the pre-existing secondary roads or those to be built. This redefined the whole system of access to the region, the circulation of the expanding frontiers and merchandise in the East-West direction. The construction of this highway led to a faster advance of cropland fronts following the highway, moving towards Araguaia and the Xingu, the first signs of considerable changes in East Amazon. These changes, however, were only to be deeply felt ten years later when the Transamazonica and Cuiabá-Santarém highways were built. At the same time, during this period, there was a sharp rise in the number of small farmers expelled from the Northeast, who had been advised and encouraged to move onto the fore-amazon and Amazon lands where, according to the propaganda, there was plenty of free land. 283
8 The rate and intensity of this occupation meant, as a rule, a dramatic break from the activities that were being reproduced in the demographic void, within a social and economic diversity that basically sheltered a population formed of Indians, riverside dwellers and some Northeastern immigrants, many of whom were mestizos, attracted by the successive booms in the extractivist economy. From 1960 to 1980, the Amazon population grew from 2.6 to 11 million. The population boom is again the result of migration. In an attempt to improve the organization of this occupation process, INCRA (National Institute of Settlement and Land Reform) was created in 1970 in order to organize and undertake land reform and to organize, coordinate, control and carry out colonization. According to IBASE (1985), INCRA would have moved around 400,000 settlers to the Amazon region between 1970 and Directed settlement appeared as one of the most significant forms during this intense occupation process over the last twenty years. In general, settlement projects do not have a uniform pattern, differing from each other in terms of area occupied and the nature of the enterprise. Although they have the same government policy, they have different aspects of access to the land through settlement. The official settlement projects undertaken by the government were scattered over East Amazon (Altamira, Itaituba, Marabá, Carajás II and III, in the state of Pará; Barra do Corda in Maranhão), while in West Amazon they tend to concentrate in Rondonia. They may be of three types: integrated colonization projects, directed settlement and joint settlement. They covered 73.4% (7,104,285.3 hectares) of the land appropriated for this purpose. Private colonization projects, however, by private enterprise occur predominantly in Mato Grosso, such as, for instance, those in Sinop, Alta Floresta and Juína. These projects cover 26.6% of the whole area (2,573,485.6 hectares). If, on one hand, in terms of land penetration, land, mines and forest ownership, and economic and political organization of the region, it can be considered as the last devastation, it may, on the other hand, mean a new beginning. THE PRESSURES CONTINUE S. A new phase appeared in the early 1980s as a reflection of the new world economic order, dictated by a structured raw material market on a worldwide scale. The commitment of this economy caused the retrieval of resources which have now become scarce (timber, hydroelectricity), use of other resources in a growing demand for modern technology (aluminum), in addition to the lower costs of abundant traditional raw materials in the area (iron ore). From a Brazilian viewpoint, the 1980s represented the implementation of a modernization policy of this territory, with a view to industrialization of the Amazon and exploitation of its mineral resources on updated bases. It was in the eighties that the Grand Carajás Project (PGC) was installed, considered in terms of both physical area (900,000 km 2 ) and projected investments as one of the largest integrated development projects ever begun by a developing country (Hall, 1990). 284
9 Basically this new project led by the State brings demands for timber, hydroelectric power, organizes the opening of areas for mineral exploitation and provides new mobility for the population in the Amazon area. In the wake of these demands comes the new mobility of the population inside the Amazon region itself, especially from immigrants from Maranhão. They are encouraged to move to areas where they are needed as manpower in the building of the infrastructure (Carajás railroad, mining area, steel mills, etc.) and for future industry. Interaction between demands, exploitation of resources and need for labor caused a spatial disorganization of the deprived social segments who eventually consider the exploitation of this asset as an alternative for survival. Groups of migration were seen within and outside the Amazon (Mid-West and South). This was seen in the gold rush (prospectors and small companies), of which the best known example is Serra Pelada. This boom reached its peak in 1985 when more than 500,000 people converged on this area, crammed together in towns, such as, Marabá, Eldorado do Carajás, Curionópolis, Parauapebas and Rio Verde. This is the second major ecological and human change in eastern Amazon. As an outcome of these induced geographic organization projects in the Amazon (Ferreira et al, 1995, 1996), it was found that between 1976 and 1991 around 35.61% of the area where the vegetation is seasonal and rain forests and 20.41% of the contact areas were rain/seasonal forest, was impacted and/or deforested. If we take into account the other non-forest vegetation, in 1991 we have a total of 14.07% of the Brazilian Amazon territory impacted and/or deforested (Fig. 3). These figures correspond to the total percentage of the Brazilian Amazon area converted into pastureland, farming areas, lumbering, mining, prospecting, plant extractivism and urban areas. NEW ECONOMIC PRESSURES AND DEFORESTATION 1990S. The nineties seems to bring in its wake a new reference point regarding the role of this region, caused by further changes of a world economic and political order. This is a new phase now in relation to the scientific-technological revolution, environmental crisis and social movements. The transforming forces, previously exclusively external, now blend with the national and local internal demands. The Amazon is becoming the product of local, regional, national, international and planetary demands. Its future is the world s future. In this new context where the technical-ecological vector characterizes the production methods, the Amazon has become the center of a worldwide debate. According to Becker (1996), all elements in this vector are present in Brazil and much more clearly in the Amazon, which has become the contradictory synthesis of the prevailing industrialist and eco-developmentalist models at the end of the millennium. For this new production method, nature is valued as capital with future returns for native populations and environmentalist movements. Nature is valued as a source and means of life, while it is still the essential basis of resources for productive segments and Brazilian society in general. However, although the technical-ecological vector emerges as a debate that seems to permit the preservation of this geographical area, it is found, on the other hand, that 285
10 286 there are accentuated external economic demands for staple raw materials (principally timber) and primary products (cereals) that again put heavy pressure on this region because of the exhaustion of other areas. The rise in deforestation rates disclosed by INPE (figure 4 ), principally in 1990 and 1991, and IBGE s mapping of human development seem to indicate that these new demands are already in the pipeline. If we look at the deforestation rate per state (figure 5 ), we will see that the states of Rondonia and Mato Grosso showed a progressively higher rise in deforestation rates for the period. The progressive increase in rates in the state of Mato Grosso can be explained by the advance of the soybean agribusiness that is already moving into the southern areas of Pará and Maranhão. On the other hand, when we look at the graphs on urban and rural population growth (figures 6 and 7), we see that since the 1980s both West and East Amazon have undergone an increasing urbanization process of their populations, headed by the states of Amazonas and Mato Grosso, followed on a lesser scale by Rondonia and Acre. If we compare the graphs on urban and rural population growth and the deforestation rates in the Amazon we will see that a population growth in rural areas does not correspond to this substantial increase in deforestation rates. This offers us the hypothesis that progressive deforestation is not a product of direct demographic pressure but rather of transforming economic forces entailing technological packages which exclude large quantities of manpower. Such transforming agents represent pressure groups at local, regional and international levels. This hypothesis is confirmed by the types of international and national demands (Figures 8 and 9) that exert more pressure on this region. The products in most demand are represented by timber, cattle raising and cereals, activities which absorb little manpower but with a high spatial capacity for destroying the ecological mosaic. Grain farming, although representing a recent demand, has been encroaching on the remaining savanna areas in northern Mato Grosso and southern Pará since 1988 as the IBGE mapping reveals (1995). Today this cereal production is already encroaching on the forest-savanna transition areas. This new order of devastation is currently reflected in the disordered growth of the towns that, in some places in the Amazon, have even had a relative growth of 7,000% between 1980 and 1991 (IBGE, 1995). These towns have become the locus of a cultural and ethnic disruption, with the consequent loss of identity by native segments who have for centuries adapted to the regional ecosystems. Questions of health arise in this complex urban scenario and this last decade has seen a substantial increase in the incidence of endemic diseases, principally malaria, cutaneous leishmaniasis, typhoid, leptospirrose and leprosy (IBGE, 1995). The figures undeniably demonstrate the importance of the different social segments in the progressive transformation of the Amazon domain and the external transforming agents that are able to engender processes hard to control at a regional and national level. It is, however, necessary for us to identify as early as possible the new pointers of the human dimension that now emerge and those that may potentially arise with a view to being able to supply not only past but future models of scenarios of changes in the biosphere-atmosphere.
11 Lastly, it is important to remember that at the end of this millenium, the Amazon domain is at the same time one of the last vast and wealthy sparsely populated areas on the planet and one of the world s most complex and vulnerable ecosystems which makes its development an incognito and a challenge to world and national sciences (Becker, 1996). V - THE EVOLUTION OF THE SCIENTIFIC KNOWLEDGE OF AMAZONIA. THE FIRST DESCRIPTIONS The stories of the first conquerors who traveled as far as the Brazilian Amazon attest to their wonder at the sight of such natural abundance. The presence of adventurers from many European countries was a sign that this territory was coveted by n means few European powers, and that, on beholding such tropical lushness and biodiversity, they believed that they had found in the Amazon a fortune that would make each common conqueror a wealthier man than the Portuguese king himself. They believed that this land was part of the earthly paradise or the mythical Renaissance cities (El Dorado, Land of the Amazons). We owe the first accounts of this region to the Dominican friar, Caspar de Carvajal, who wrote in detail of the expedition of Francisco Orellana, Spanish conquistador, who founded Guayaquil and brother of the cruel Gonzalo Pizarro, who annihilated the Inca empire. The first journey along the Amazon river was made following the waters eastwards from the West. Friar Carvajal s writings are the first descriptions of the general characteristics of the river with the largest volume of freshwater on Earth. This navigation took around eight months and ended in August One of the interesting facts mentioned by Carvajal is the existence of the Amazons, described by him as women who courageously fought with bows and arrows, were naked and wore their hair very long, in plaits entwined around their heads, and that they were organized socially in groups of villages. Even today we are not sure if this people had light skin, if they really existed, if Carvajal had mistaken them for longhaired men, or if he unwittingly adopted the Greek myth of the Amazons. The fact is that this is why the great river along which they sailed became known as the river of the Amazons. The accounts of all these journeys tell us that there were people living in organized communities along the Amazon, under the command of a chief, with large tracts of land and remarkable buildings, but we are not sure how many there were. (Oliveira, 1983) These indigenous peoples had sophisticated in-depth knowledge of the ecosystem and farming and several species were domesticated for food or otherwise by the Amazon nations, and which are still used by us today. These Indians, living in the floodplains or forests (mainland), were knowledgeable about and used a large variety of plants such as: tubers, bulbs, seeds, fruit, nuts and other plant products. The vegetation also supplied poisons for hunting and war, in addition to medicinal products and drugs used to cure some diseases and in religious rituals. The forest was also the source of timber for firewood, to build utensils, weapons and cabins, as well as a source of material for basketry, clothes, resins, oils and pigments. The fauna supplied food, especially meat, eggs, insects and honey, as well as ornamental and building material for instruments and weapons. 287
12 Between 1637 and 1639, the Portuguese captain Pedro de Teixeira led an expedition from Belém to Quito and back to Belém. On the return journey, from Quito to Belém, Pedro Teixeira is assisted by Father Acuña, who in 1641 publishes the Nuevo Descubrimiento del Gran Rio de las Amazonas in Madrid, the most detailed treaty until then on the nature of the tropical region and the uses and customs of the Indians. In 1743, Charles Marie de La Condamine, entrusted by the Science Academy of Paris to set the exact coordinates of the land Equator, sails up the Amazon river and, after enduring a series of hardships on his expedition, returns to Paris and leaves a vivid account of the aspects of nature in the tropics. However, the best account of the Amazon is found in the report of two emissaries from the Portuguese court. The report by Francisco Xavier Ribeiro de Sampaio, in , as justice of the peace and General Overseer of the River Negro administrative division, covers vast regions, as he visited indigenous villages to find slaves. The most detailed and only report written by a naturalist is still consulted today by scientists and students of the Amazon, and we owe it to a Brazilian, born in Salvador, who studied Natural History at Coimbra University. Alexandre Rodrigues Ferreira ( ), when 27 years old, was commissioned by the Portuguese court to write a scientific report on the river Negro. Between 1785 and 1791, Rodrigues Ferreira collected animals and plants, visited Indian villages, where he gather ethnological material, drew numerous drawings on several aspects of nature and indigenous customs. On his return to Portugal, he wrote Viagem Filosófica pela Capitania do Rio Negro (Ferreira, A. R., 1792). He was a renowned scientist and became administrator of the Royal Botanical Garden in Lisbon. After the earthquake in that city and the Napoleonic wars, his collections and publications were scattered and few have survived. THE CLASSIC ERA There is no doubt, however, that the 19th century is the era of the great naturalists. We have from this time the best collections and studies of Amazon plants and animals. The systematic and taxonomic studies, on which scientific knowledge of this forest s biodiversity is based, was undertaken by Humbold and Bonpland who spent the years from 1799 to 1800 sailing along the Cassiquiare channel between the Orinoco and Negro rivers. Then, between 1817 and 1820, two other great German scientists, Spix and Martius sailed down the Amazon, exploring the Juruá and Madeira rivers. There were several other accounts by military men and priests during these years, with the main focus on indigenous problems, with nature on a secondary plane. Some examples are that of Major João Henrique de Mattos, in 1825, who mentions the decadence of the Indians in the upper Negro river. By Navy Lieutenant Henry Lister Maw, in 1828, who arrived in Brazil at Tabatinga, and traveled as far as Belém, leaving us accounts of civilized Indians. Sir Robert H. Schomburgk, from Prussia, who visited between 1838 and 1842, employed by the Royal Geographical Society of London, explores and maps the region between Brazil and Guyana. His numerous collections are kept at the British Museum and his cartographic studies were used, at the International Court of The Hague, to arbitrate in favor of Brazil, the dispute on the boundary lines between Brazil and former British Guiana. 288
13 In the mid-19th century, four outstanding naturalists broadened and founded the tropical taxonomic science. Alfred R. Wallace, entomologist, gathered his Amazon collections in the period. He visited and collected mainly fauna from Belém in Pará to the upper river Negro. His notes, drawings, articles and most of his collections were lost in a fire on the ship that carried Wallace back to England. His friend and also entomologist, Henry W. Bates, also visited the Amazon and explored the Amazon river tributaries. He stayed for eleven years ( ) in the region and his vast collection reached England safe and sound. TURTLE OIL The Spanish and Portuguese conquistadors told how the Indians, during the ebb tide, would capture a large number of turtles. They were left imprisoned in small lakes to fatten and were then used as food when they reached adulthood. This primitive management system can still be found in remote communities. The oil taken from turtle eggs started with the Europeans, as there is no record of the Amerindian peoples using this oil since they were only interested in the fresh meat and eggs as food. The oil is obtained by breaking thousands of eggs under the hull of a canoe, crushed and mixed with the oar until a mixture is obtained from which the fat is removed and placed in large mortars for purification and reduction. Henry Bates calculates that to fill a pot (unrecorded volume) 6,000 eggs would be needed and that, in the region of the upper Solimões and Madeira rivers, 48 million eggs were destroyed every year. This corresponds to 400,000 turtle nests. From his entomological collections, it has been possible to describe 3,000 new species of insect. Richard Spruce, an American naturalist, who between 1849 and 1855 followed in the steps of those two above, formed an important collection on the regional flora. There is no shadow of doubt that these three men were the forerunners of taxonomic knowledge of the biodiversity of the tropical rain forest. The American ichthyologist couple Agassiz traveled the Amazon rivers and gathered the largest collection of fish ever. By the end of the century their publications were the bible of taxonomic studies on Amazon fish. In the late 19th century (October 6, 1866), Brazil founded a Research Institution that is now called the Emilio Goeldi Museum in Pará. For the first time, scientific research was now based in a local institution. In addition to studies on birds by Goeldi himself, mention should be given to the work on fish and fishing by Verissímo, which is still being quoted. From the studies carried out by the Goeldi Museum, scientific research was consolidated as an ongoing activity of the Amazon intelligentsia. The prosperity from the rubber monopoly since 1880, reaching its peak in Brazilian production between 1910 and 1912, brought significant improvements to the region but this did not reflect in scientific research. However, since 1914 with the decline in the Brazilian monopoly, the Brazilian government took a series of measures to save the rubber and look for alternatives for farming development. Some of the programs amplified the basic knowledge on the regional nature as they focused on research. This phase includes the Rubber Defense Plan, 1912, in the government of Hermes da Fonseca; the Rondon Commission, , started by president Afonso Pena, extended studies on the indigenous communities; land concessions to 289
14 the Japanese for exploiting jute and then black pepper coincides with the formation of farming cooperatives and the creation of the Northern Agronomy Institute in 1941, to undertake research on plant production, species acclimatization and soil and forest identification. The Emílio Goeldi Museum of Pará and Northern Agronomy Institute together have performed the best scientific research every done in the Amazon to date. The specialists and researchers working there have formed the basis for undertaking future investigations that today are spread throughout the universities and public institutions in all Amazon states. ORGANIZED RESEARCH With the end of the Second World War and continuing signs of internationalizing the Amazon, especially with the American proposal to create the International Institute of Amazon Hylea in a town in the Amazon region as the headquarters for international scientific research in the region, the nationalist government of Getúlio Vargas reacted and in 1952 created the National Institute of Amazon Research (INPA), based in the city of Manaus. In contrast to the Emilio Goeldi Museum of Pará, who focused for decades on systematic and anthropological research, from its early years INPA concentrated on studies of the relations between the environment and biological systems that would later lead to important research on how ecosystems are structured and operate. This new point of view originated the primordial work of Professor Sioli on the river system in the region. The division between white, black and clear waters proposed by these researchers from the studies of their physical, chemical and biological characteristics were the pillars of the limnological studies on the whole Amazon region. Since the 1960s, a significant research effort has been made to establish scientific bases of the dynamic processes to maintain the ecological balance of the Amazon. By the end of the sixties two major lines of work had emerged. The first endeavored to discover the importance of the forest in the water cycle, especially investigating if large-scale deforestation could be an influence on climatic changes in the region. This line of work was first adopted by Eneas Salati and eventually established the Amazon water cycle (Salati & Vosse, 1984). The second line of work sought to discover the importance of nutrient recycling in maintaining the primary productivity of the forests, that is, the continuation of the forest biodiversity. This kind of work was undertaken in the laboratory by Herbert Schubart and his results were summarized in two important publications (Schubart,1983; and, Schubart,1998). THE FOREST AND THE WATER CYCLE The work performed since the end of the sixties to date shows that the forest vegetation plays a relevant role in the influence of the water and solar energy balance (Salati & Marques, 1984; Salati et al, 1978; Salati et al 1979; Salati and Volsen, 1984; Salati et al, 1990; Salati and Nobre, 1991). Many papers have been published stressing the importance of the Amazon rain forest and the maintenance of the climate within this region, as well as the areas around the Amazon and even global climate changes. 290
15 The main functions of the rain forest affecting the climate balance in the Amazon region are listed below: due to its structure, the forest intercepts the rain causing direct evaporation and returning water vapor to the atmosphere. The amount of water vapor generated thus depends on the structure of the forest, and this figure varys from 17%-25% of precipitation for dense forest areas; trees within the forest structure act as pumps carrying water from the soil to the atmosphere. During this transpiration process, the energy needed to transfer the water from the liquid to the gaseous state comes merely from sunlight. In dense forests, this process represents approximately 50% of rainfall; the forests avoid surface run-off as the soil is covered by a thick layer of organic matter with a large water infiltration capacity. This means that the forest increases the length of time during which the water remains in the ecosystems, allowing the plants to act as systems transporting water from the soil to the atmosphere through transpiration; the forest controls the energy balance of the ecosystem. Studies show that some 75% of solar energy is used in a dense forest to evaporate water through direct evaporation of water retained in the canopy and plant transpiration. Deforestation alters this energy balance, as well as the water balance. Based on this information and mathematical modeling, the forest system has been shown as an important factor for maintaining both regional and global climates. Deforestation could well result in climate changes at the local, regional (Gash et al, 1996) and global levels. The appearance of global climate changes deriving from deforestation in the Amazon is particularly related to: quantitative alterations in the transportation of energy and water vapor from the Equatorial regions to higher latitudes; the emission of greenhouse gases produced by deforestation and burn-offs with CO 2 taken into consideration. Another aspect that should be recalled is the emission of nitrogen oxides produced during burn-offs. Due to deforestation, direct CO emissions in the Brazilian Amazon are estimated at 2 some 0.3 GtC. These figures have prompted countless discussions due to relative uncertainty over deforestation rates and the quantity of biomass associated with cleared ecosystems. THE FOREST AND THE NUTRIENTS CYCLE. Schubart, in 1998, made an excellent summary of the role of the forest in recycling nutrients. The problems of establishing sustainable agriculture in the Amazon region are mostly the result of the break in this dynamic process with the forest ecosystem. Shubart summarizes as follows: In the Brazilian part of the Amazon, the vegetation types of the vast Hylaea of about 3.7 million square kilometers are divided into 89% of non-flooded dense tropic rain forests, 2% of flooded forests, 6% of open vegetation types like savannas and campinaranas, and 3% of aquatic vegetation, rivers and lakes (Braga, 1979). The non-flooded dense rain forests are, therefore, by far the most representative forest cover of the region and will be thus specially considered here. 291
16 292 The two most conspicuous aspects of the structure of these forests are certainly the high biomass and the extremely high biological diversity. A complete sampling of a 2,000 square meters plot (0.2 hectare) of dense rain forest, growing on an oxisol near Manaus, found an amount of about 500 metric tons per hectare of plant biomass (dry weight), 14% of which was root biomass. This sampling also established the presence of 502 different tree species between one and 40 meters in height, distributed among at least 60 plants families (Klinge, 1973; 1976; 1983). None of these species showed any particular dominance over the others. The thick forest around Manaus is clearly stratified in four stories: trees taller than 15 meters; trees between 12 and 15 meters; small trees and shrubs between 7 and 12 meters; and seedlings, saplings and shrubs less than 7 meters tall. The highest story has less individuals and species. There are not many emergent trees higher than 30 meters (about 4 to 10 trees per hectare). Twelve species in this area exceed 35 meters height, among which Dinizia excelsa, a legume tree, which is reported as the tallest tree in Amazonia, with a record of a 55 meters tall specimen. The diameters of the tree trunks of most species are not very large, at below 85 centimeters. Only 10 species were found with trunk diameters of more than 85 centimeters, including one tree of Dinizia excelsa with two meters. Other structural elements of the vegetation include palms, lianas, ferns, mosses and epiphytes. Their biomass is not quantitatively important, but they do represent an expressive share of the forest biodiversity and are functionally very important. A study of the distribution of fine roots (diameters < 10 millimeters) and soil fauna (mainly arthropods), in two soil profiles to the depth of 1.6 meters, showed that about 85% of the dry weight of less than 2 millimeter roots and 66% of the roots between 2 and 10 millimeters are found in the top 10 centimeters of the soil. The same trend is true for the distribution of soil fauna: 84% of the total catch (expressed in number of individuals) in the mentioned profiles also occurred in the top 10 centimeters (Chauvel, Guillaumet and Schubart, 1987). There are no really large animals in the Amazon rain forest. Of course, some of the world s largest insects and spiders do live a hidden existence in its shade. Among the large vertebrate predators are the jaguars and pumas, bush dogs and other dog-like species, the harpy eagle and several hawks, falcons and owls, besides a variety of snakes, toads and frogs. The largest herbivore mammal is the tapir, followed by several other groups of herbivorous or omnivorous animals, like deer, peccaries, agoutis and smaller rodents, opossums and other marsupials, the edentate armadillos and the tree climbing sloth, monkeys and marmosets, many insect or fruit eating bats, and a multitude of birds. A long term research project being carried out North of Manaus to assess the impact of forest fragmentation on plant and animal diversity (Lovejoy et al., 1983) has inventoried the vertebrates occurring in the area as follows: 44 species of amphibians, 89 species of reptiles, 300 species of forest birds and 51 non-flying mammals. It is interesting to note that the bats - flying mammals - are more species-rich than all other mammals together in the same area, amounting to between 60 to 65 species. Then, there is a host of insects. The high diversity of plants seems to be at the origin of the high diversity in insects, due to the generally tight species-specific relationships between plant-eating insects and their feed plants. As a matter of fact, the number of species of these insects, and of their predators and parasites, can be very high indeed, as studies of the forest canopy insect fauna have shown. According to
17 these estimates, the number of species of insects in all tropical forest could be as high as 30 to 50 million (Erwin, 1988). However; the total animal biomass in the dense rain forest ecosystem is not so high when compared with plant biomass. A rough estimate of these biomass figures, expressed as fresh weight per hectare, reads as follows: 1,000 tons of living plants, of which 20 tons are leaves; 30 kilograms of herbivorous animals; 15 kilograms of carnivorous animals; 165 kilograms of soil fauna; an unknown amount of soil fungi biomass; and 100 tons of dead organic matter, mostly of plant origin. Most of this animal biomass consists of invertebrates, especially insects. The importance of the soil fauna, especially ants and termites, is particularly remarkable. In terms of food chains, the rain forest ecosystem may be separated into two subsystems. The first is based on the direct consumption of leaves, fruits, nectar and parts of other living plants by insects, birds, bats, monkeys and other herbivorous animals, which in their turn fall prey to predators or carnivorous animals. The energy flowing through this so-called autotrophic food chain is only about 10% of the total solar energy fixed by the green forest plants.the remaining 90% of solar energy stored in plant tissues leaves, flowers, fruits, bark, wood, etc. as the leaves or the whole plant die, is transferred to the dead organic matter of the soil as leaf litter, dead tree trunks, rotten fruits, and the like. This raw organic matter store is the starting point of a very important food chain, in which the soil fungi and bacteria play an essential role as organic matter decays. This basic function is enhanced by the activity of a myriad of mites, springtails, millipedes, termites, wood lice, earthworms, ants, pseudo-scorpions, spiders, nematodes, protozoans, and so on, which constitute a complex food web of detritivorous and fungivorous organisms and their predators. All the biological activity in this so called heterotrophic food chain results in the breakdown and humification of the raw organic matter, the release of mineral nutrients to the plants, and the building up of porosity along the soil profile by the activity of soil animals, especially termites, ants and earthworms. The mean yearly production of dead leaves and other fine debris by the forest trees varies between 6 to 8 tons per hectare around Manaus, and 10 tons per hectare around Belém. This litter fall is greatest during the drier months of the year; when leaf litter builds up on the soil. The breakdown of this leaf litter; on the contrary, is more intense and very fast during the rainy season, when the dead leaves may completely decay in about one month. These lush dense rain forests thrive on the very mineral-poor soils described in the previous section, a situation that at first seems a paradox. The explanation is, nevertheless, simple: these rain forests store in their biomass, and recycle, all the mineral nutrients. The concentrations in the water of the forest streams and rivers that drain these systems, are minor and comparable to the small mineral inputs from the rainfall and from the weathering of the already impoverished soil parent material. The conclusion is that the Amazon rain forest ecosystem is very efficient in retaining and recycling its essential mineral supplies under a regime of very high rainfall. Actually, these forests have been described as biological mineral filters, in which the complementary and finely tuned functions of a multitude of trees and their fine roots, epiphytes, animals and microorganisms, together, help to find and consume any remaining small piece of nutritious food, or any leaking droplet or mineral concentrate. In this model, therefore, the reportedly high biodiversity of the rain forest plays a very central role, which is schematically shown in Figure 3. Without 293
18 attempting to explain every relationship depicted in this diagram, it is worthwhile pointing out a few of them. First, the tropical climate conditions are very favorable to plant production. However, these same conditions also favor the year-round development of insects, fungi and bacteria as plant pests and disease agents, and also cause the intensive weathering of clay mineral and leaching of soil nutrients. Both of these last mentioned consequences pressure of plant predators and parasites, and impoverished soils favor the increase in plant diversity by different means. The first, by decimating any clustering of a single species natural single crops which could occur in the forest as, for instance, all the seedlings germinating under the mother tree. Isolated individuals are statistically harder to find by their natural enemies and are, therefore, less vulnerable). As a result of this pressure of phytophagous insects and disease agents on plant populations, the forest ecosystem develops a higher plant diversity in equilibrium. Here, the importance of seed dispersal by birds, bats, agoutis, monkeys, etc. to maintain the plant diversity of the rain forest becomes evident. The second consequence impoverished soils and their role in plant diversity can be explained by the growth rates of different plant species under different soil nutritional status. In fertile soils, some species grow very rapidly and occupy all the available space, to the exclusion of many other species. In more mineral-impoverished soils, no species can grow fast enough to exclude the others. Once again, the outcome will be a more species-rich plant community. RECENT INTERNATIONAL COOPERATION Since the eighties, a series of projects began in INPA in cooperation with international and Brazilian institutions outside the region, which introduced an integrated view of the importance of the Amazon for the planet and the effects of global anthropic changes on the region. Integrated projects are also underway to investigate the ecological relations established during the evolution process of the Amazon biota. Two lines of research started in the late seventies consolidated the knowledge about the structure and functioning of the non-flooded and floodplain ecosystems. Since then, with growing international concern for the effects of deforestation on the biodiversity of the non-flooded forest, a research team was created in INPA to study the effects of fragmentation on the ecosystems through the Biological Dynamics of Forest Fragments Project (Projeto Dinâmica Biológica de Fragmentos Florestais - PDBFF). This program, now more than 20 years old, trained 39 new Masters and Ph.D. researchers, and every year holds a course on tropical ecology for students from the whole of Latin America, as well as producing vast literature on fragmentation issues. Based on 11 forest fragments close to Manaus, this project is the result of a bilateral cooperation agreement between INPA and the Smithsonian Institution. The results already obtained from basic research help towards drawing up social integration policies and developments more suitable to ecological relations. With regard to the floodplains, the projects by INPA and the German Max Planck Institute on the influence of the ebb and flow pattern on the ecology and biology of the floodable areas, were also the basis of the ecological and anthropic relations of this Amazon ecosystem, which have historically been most impacted by man since the Indians set up home along the rivers (Junk, 1997). This line of work led to the application of basic research studies on a proposal of sustainable development for 294
19 the Amazon floodplains, through German-Brazilian cooperation that produced the Program of Studies of Human Impacts on Tropical Forests and Plains - SHIFT. Now at the end of the 1990s, awareness that the global climate changes are the result of anthropic actions and that the impacts of these changes can affect continuing economic development, creates the need to set up research programs that strive to model the anthropic effects on bio-geochemical cycles, especially with regard to the carbon cycle. From this latest point of view, Brazil and the international community have set up a research program called Large Scale Experiment on the Biosphere- Atmosphere in the Amazon. This experiment attempts to answer two major questions: how does the Amazon currently operate as a regional entity and how will the changes in the land and climate affect the biological, chemical and physical functioning of the Amazon, including its sustainability and influence on global climate. These questions will be answered through studies on the carbon exchange and storage, bio-geochemistry of trace gases and nutrients; chemistry of the atmosphere; surface hydrology and chemistry of the water and changes in land use and vegetative cover. The results will help towards the development of public policies for the sustainable used of the natural resources in the region. Obviously, the development of scientific research in the Amazon has always had international cooperation and, although still quite fragmented and with major gaps even in such basic subjects as taxonomy and systematics, it has reached a level of integration and global thinking that permits the establishment of major multidisciplinary projects in the latest international scientific investigations. VI - FACTORS THAT LIMIT SUSTAINABLE DEVELOPMENT IN THE AMAZON Sustainable development projects in the Amazon are limited by a number of environmental pressures, which are as follows: low productivity originating from the actual bio-geochemical cycle, as in the example in the following item; variation in available resources, typical of the flooded areas where the water supply cycle varies widely between seasons; biological pressure, namely pests, disease and predators that attack plantations, the clearest example being the fungus that attacks rubber trees, against the cultivation of single Hevea crops in the Amazon. In addition to these environmental pressures are the limiting factors relating to the expression of the political and economic culture, that are of a technological, institutional and market origin. In this chapter we have endeavored to show how the biological and cultural factors limit the success of economic ventures and that identifying the factors is a key to implementing sustainable development projects in the Amazon (Salati et al, 1998). FACTORS THAT LIMIT BIOLOGICAL PRODUCTIVITY IN NATURAL ECOSYSTEMS Environmental limiting factors can be easily described through understanding the primary productive process. The basis for establishing a food chain in the Earth s 295
20 296 major ecosystems depends essentially on the possibilities of organic matter production through photosynthesis. During this basic process of nature, carbon dioxide assimilated by the plants during the day produces simple organic compounds that, by biochemical processes, become more complex organic compounds. In order for this phenomenon to occur, that is, for primary production, some conditions are necessary, such as water, light, inorganic chemical elements, suitable temperature conditions and the existence of organisms that can produce photosynthesis. With the exception of the polar regions, there is always some plant species that can survive and produce organic matter, which accumulates for some time and then is fully or partly oxidized. This basic process, occurring on Earth for at least the last 3.2 billion years, permits the accumulation of a large quantity of carbon in the form of organic compounds. The animal kingdom depends for its survival on basic organic matter that is the start of quite a complex food chain in the various ecosystems on the planet. This ability to produce organic matter, that is, biochemical fixation of carbon, depends on numerous factors that define and determine the exuberance of the ecosystem under study. The lack of conditions for plant growth can be described by limiting factors that hinder or prevent efficient photosynthesis of a certain species or plant community. When addressing a farming ecosystem, that is, the production system in which man utilizes the photosynthetic conversion to supply his food requirements, the appearance of limiting factors should be avoided. This is possible by using farming techniques where, for instance, only selected crops adapted to the local ecological conditions are planted. The development of the root system should be maximized, in order for a more efficient absorption of mineral nutrients and water required to increase production. Selected crops have the advantage of resisting local diseases. In some natural ecosystems, the limiting factors in the cultivation of farming species are so obvious that no attempt is made to do so. Thus, for example, in the desert regions like the Sahara, for instance, the obvious limiting factor is water. Thereby, before any farming activity or plan of action is adopted, it is necessary to find out if there are water sources in order to cancel out the most important limiting factor. In other regions, the limiting factor for farming cultivation is the temperature. In large regions, such as, Siberia and some very high plateaus (Tibet, Chile), the average temperatures during the year discourage the growth of exotic crops in the open air. In this limiting situation, some kind of farming activity can be performed by using artificial systems, including greenhouses, which permit the cultivation of some plants of economic interest. Another limiting factor in tropical, temperate or semi-arid climates is soil fertility. The reason for low fertility can sometimes be related to the origin and evolution of the soil; at other times, the degradation of the ecosystem by anthropic action accelerates erosion and the leaching process, resulting in barren soil, unproductive in farming terms. In this case, the problem is solved by using specific techniques, such as, proper soil management, cultivating pioneer species, using nitrogen-fixing plants and artificial fertilizers, including macro and micro-nutrients. The productivity of various natural ecosystems in the Amazon is closely linked to the characteristics of the soils. Evidence of this fact is the existence in the Manaus region of very different ecosystems with a variable biomass from a few dozen to 400

A series of very large ocean waves which are caused by large disturbances such as an underwater earthquake or volcanic eruption, or meteorite impacts from above. Tsunami waves are of extremely long length and period and they move outwards, away from their source. This allows time for the tsunami to grow in wave height. As a tsunami crosses a deep ocean, the length from crest to crest may be as much as 150 km but the height may be less than a metre. Tsunami waves may therefore be unnoticed by ships or from the air, reaching speeds up to 1000 km per hour.

I am from Edinburgh and am going to be studying humanities soon, then English, I think, not decided yet. :)
Also, I'm about two quarters French, a quarter Irish, a quarter Scottish, have ADHD and have a weird name... :)
I love photography its one of my favourite things (published), check out my photos here on my photo page on flickr:
Also make techno with my synth and guitar :) check my Soundcloud out, you can download my songs if you like. :P x
Also really lonely and needing a girlfriend. :(
:) x
Hmm, maybe thinking laterally, or philosophically, and listening in such a way that if there is some kind of problem I almost always have a solution. :P
ADHD is great for certain things like creative thinking but organisation, not so much.
Being generally creative I suppose, I love taking pictures and making music, short films and stuff. :)
I'm usually a nervous wreck around girls I've just met, that I like but I quickly get used to the company of people I "connect" with, so to speak. :)
(B) Heat by Michael Mann, Apocalypse Now by Francis Ford Coppola, Alien by Ridley Scott, Bladerunner by Ridley Scott, Leon by Luc Besson, Akira by Katsuhiro Otomo, Ghost in the Shell by Mamouro Oshii and Titus by Julie Taymor. My favourite directors are, Michael Mann, Luc Besson, Ridley Scott, Steven Speilberg, Francis Ford Coppola, his daughter Sofia Coppola and George Lucas for Star Wars.
(C) My fave band is U2 (mostly their 1990s stuff), I also love Elliot Goldenthal who is an excellent composer; also The Future Sound of London who are probably the most brilliant electronica act ever, Aphex Twin, Autechre, Leftfield, Underworld, Faith no More, Sex Pistols, Public Image Ltd., Pixies, Garbage (90s stuff), Smashing Pumpkins, Nirvana, The Smiths, Melt-Banana, Radiohead, Fluke, Orbital, The Orb, Madonna's 90s stuff (most other stuff shes done sucks, 'specially the recent and 00s stuff; the "Justify my Love' (1990) and 'Erotica' (1992) videos and songs are HOT, lol), Vangelis, Brian Eno, Bjork, Jerry Goldsmith, The Prodigy's 90s album's, The Chemical Brothers; and LOADS more, I think the best decade for music, in the last few, was the 90's, lol.
(D) I love Italian food; I'm not too fussy about food though.
1. My Ritalin....:P
2. Thinking about stuff constantly (minds always going) and philosophy.
3. My few, but very close friends.
4. Movies, music, anything creatively inspiring.
5. Number 5 eludes me.
6. Coffee, cigs, ginger beer; I like my vices. :)
I don't go out much. All my mates live in Stirling so Ive never actually tried to go out and meet new people here in Edinburgh, so that's partly why I'm on here! Preferably closer to me than Stirling or Dunfermline! :)
I dunno!

Hi Sandro, I'm not necessarily suggesting we attempt to translate standard CSS style properties to Pivot skin properties. I think that's something that has to fall out of a prototype implementation. I am suggesting we use and support a subset of the CSS syntax for documents, selectors, properties, etc. I am working on a prototype, though I'm not sure when I'll make it public. Again, it depends on how it goes.... :) Michael On Sun, 4 Jul 2010, Sandro Martini wrote: > Hi to all, > I agree with Michael that designers etc would prefer another standard > for styling Pivot applications, at least as a starting point. > > But I agree with Greg, I think that a practical solution for Pivot > could be a CSSSerializer, used with the new syntax like this: > > <bxml:include bxml:id="styles" src="styles.css"/> > > fter this, there is the problem to map css standard properties to > Pivot components, but maybe this could be done using another (related) > component, like CSSTransformer / CSSMapper ... but to have this work > in a transparent way probably we need some adjustment to Pivot, and > here Greg can tell us if this is a reasonable change. > Because changing Pivot styles to adhere to CSS naming I think it's NOT > a good idea, and otherwise I don't think someone will write a CSS NOT > containing standard definitions. > > What do you think ? > > Michael, can you create an issue for this in JIRA (possibly with a > reference to all this discussion) ?

The Vanishing(2015)
(The first book in the Creation Game series)
A novel by David Callinan
Morgan Lane (15) has a superhuman memory and a gift for designing amazing 'gizmos'. Together with his sidekick, the Chinese American Lin Rainbow, who has the power of prophecy; and their pet orangutan Winston - transformed by magic and science into a genius with the power of speech - he is catapulted into a cosmic adventure across the multiverse to the dimension where time and space are one. The comet Cygnus Hyperbole heralds an amazing event: the sudden disappearance of all animal life on Earth. The mysterious Guardians choose Morgan to memorise 'The Cosmic Algorithm', the key to all creation as a power-crazed scientist (controlled by cosmic parasites known as the Shadix) designs replacement animals, nanosaurs, including Taurus, a seventeen-feet tall minotaur - the first of a nanosaur army destined to control all mankind. But the world is descending into chaos as Morgan and friends battle across an unrecognizable earthly landscape to find the gatekeeper to the next dimension - the Kingdom of Time And Space.

Published on Apr 01, 2016 Editor's Pick Who needs comfort when you can have the extra scrubbing power of fiber and splinters to help get those last bits of doo-doo off your derriere? Georgia Pacific's Quilted Northern has debuted a new line of specialty TP, what it bills as the "biggest innovation in toilet paper since the 3-ply roll." The new product brings an artisanal, handcrafted sensibility to an unlikely realm, the potty, with varieties that include the Small Batch Rustic Weave, Cedar Loom and Extra Virgin Birch -- for those of you who prefer more bark on your butt. Any of these would make for an especially charming accessory to back-to-the-earth homemakers who prefer a hole in the ground to the latest ceramic throne. Created out of Droga5, the ad promoting the product says, "It's tissue that's genuinely tree to toilet, for a more memorable bathroom experience." The idea is a sharp contrast to the brand's "Designed to Be Forgotten" tagline, and indeed, Quilted Northern says the idea "rolls back 100 years of innovation." Go to QuiltedNorthern.com for more details -- but only just for today, you April Fool. See more brand holiday pranks in AdAge's roundup. Rate this Ad You must be registered to rate the ad.
