Environment and livelihoods in tropical coastal zones: managing agriculture-fishery-aquaculture conflicts.

Book cover for Environment and livelihoods in tropical coastal zones: managing agriculture-fishery-aquaculture conflicts.


This book contains 22 selected papers presented at the title conference. These papers focus on the challenges people face in managing crops, aquaculture, fisheries and related ecosystems in inland areas of coastal zones in the tropics. A priority issue that emerges from the case studies presented in this book is the impact of change on poor people whose livelihoods depend upon open-access resource...

Coastal water resource use for higher productivity: participatory research for increasing cropping intensity in Bangladesh.

In Bangladesh, approximately 1 million ha of coastal saline soils have been monocropped with low-yielding, traditional rice varieties during the monsoon season from June to December. Most of these lands remain fallow in the dry season because of high soil salinity and the lack of good-quality irrigation water. This research was conducted during 2001-04 with farmers' participation to test the hypothesis that a combination of on-farm storage of surface water, to prolong freshwater availability beyond the end of the rainy season, together with the proper selection of rice varieties, can increase cropping intensity and productivity of the area. Selected farmers and local leaders were involved in the whole process, from designing the new cropping systems to managing, testing and evaluation. In the wet season, the traditional rice varieties were replaced by short-duration, high-yielding varieties (HYV), which can be harvested earlier, ∼1.5 months before traditional varieties. This opened up opportunities for early establishment (in mid-November) of short-duration HYV of rice during the dry season. River water was directly used for irrigation of the dry-season crop up to mid-February. Beyond this time, river water became too saline for irrigation purposes. Before it became too saline, river water was taken in through sluices in the first week of February and conserved in on-farm canal networks. The stored water was used to irrigate rice from mid-February to the end of March. The new cropping system increased annual rice yield by two- to threefold and farmers' profits by 1.5- to 2-fold compared with the farmers' traditional system, and with no apparent negative effect on the environment. The technology was taken up at a fast pace, indicating that farmers preferred it to shrimp farming. Principles of the technology can be applied to other monsoon, deltaic coastal areas.
