Flood-tolerant rice leads Guyana farm adaptation push

Johann Earle in Alertnet: George Griffith is pleased with his harvest. Improved farming techniques and a different variety of rice have helped the 70-year-old farmer reap 103 bags of rice from his two-and-a-half acre (one hectare) field in this coastal village. ...“The land of itself is fertile, very fertile, (but the harvest) has a lot to do with the preparation of the land,” he said. Preparation and adaptation are the key words as Guyana’s farmers seek to increase their incomes while adapting to unpredictable weather conditions. The pressures of a changing climate are forcing a rethink of agricultural practices by individual farmers and the government.

Griffith, for instance, has been able to maximise his production using a new variety of rice, and minimise losses from climate-related flooding through adaptive measures in the field. At his farm, Griffith must deal with flooding caused by heavy spring ocean tides as well as increasingly heavy rainfall. Efforts to improve drainage have helped address the problem, but now Griffith also maintains protective banks around his fields to keep out excess water...

...To deal with wetter conditions, Griffith also is trying out a rice variety called GRDB 10. It is specially adapted to wet conditions and can survive for a few days underwater, which means that the farmer need not wait for the land to be completely drained before planting. An additional advantage of a rice plant that can endure being underwater is that it does not face as much competition from weeds and other plants, which are killed by standing water.

...Getting such crop transitions is crucial for Guyana’s rice and sugar industries, which are key contributors to the South American nation’s food security, large employers and a major source of foreign exchange for the country...
