Assessment of Bamboo resource in Chittagong region in Bangladesh by Sampling Technique

A sample survey was conducted on the homestead Bamboo plantation of the district of Chittagong in Bangladesh in 1992. A total of 14 rural thanes having a sample of 272 ha land area in the district were covered under the survey. The district has varieties of Bamboos among which Bambusa vulgaris, Melocanna baccifera and Bambusa tulda are most common species. The purpose of the survey was to estimate total Bamboo resource, its cultivated area, households with Bamboo cultivation, rate of cultivation, harvest and stocking per hectare and per clump. A Stratified Two Stage Sampling Design was followed for the survey. A sample of 900 households was considered for the purpose. The results showed that the area under Bamboo cultivation, number of clumps and number of culms were 3694 ha, 937764 and 48821592 respectively. About 42% households harvest Bamboos every year. The number of Bamboos per hectare and per clump were estimated to be 15331 and 69 respectively. A picture of overall Bamboo situation in the present homestead Agroforestry System of Bangladesh is shown on the basis of the survey results. The role of Bamboo as its contribution and economic importance is also mentioned. The necessity for assessment and monitoring of the resource is emphasized.
