摘要：In the state of Tripura, in India, agriculture contributes about 64 % of the total employment and about 48 % of the state's domestic product. Growing population and decreasing per capita land availability entails that the available land must be utilized effectively. With this broad objective, the study team took up an integrated study of "Sater Mianar Hour"- an erstwhile wetland ecosystem being used for rice cultivation. The study was basically aimed at improving the productivity of the wetland area in catchment level. Major problems of the wetland ecosystem are siltation of the natural drainages locally called charras, gradual rise of the major river bed resulting in back flow into the feeder channels causing water stagnation and flooding, mono-crop agriculture with rice alone as the dominant crop etc. Major objective of the study was to prepare land-use plan for sustainable development of the area in catchment level with inputs from sub-watersheds prioritization and Sub-surface water potential in various landforms and litho-types of the study area, where sub-watersheds were prioritized based both field and remote sensing parameters such as various parameters of drainage morphometry such as drainage density, circularity ratio etc, slope, Soil brightness index (SBI), nomalised difference vegetation index (NDVI) etc. Data from LISS III (multispectral) and LISS-IV (mono) of IRS-P6 satellite and soil maps from NBSSLUP were used to map the current land use, geomorphology, ground water prospective zones. The entire rice ecosystem has been delineated into twenty micro watersheds and prioritized into four categories such as very high, high, medium and low for taking up developmental plans on priority. It is found that most of the study area is good to very good in ground water prospect that can be used extensively during Rabi and summer season crop growing periods after carrying out quality check. The recommended package of individual appropriate land use (1:25,000 scale) in each of different priority zones of the catchment is mainly aimed at vegetative and agronomic measures for erosion control, in situ soil moisture conservation and production system. Using the database, several alternatives for water harvesting, cropping pattern, soil conservation, agro-horticulture, afforestation, etc have been suggested. Area statistics have been generated for both existing and recommended land-use pattern. Implementation of suggested land use at watershed level, based on priority, will lead to sustainable development of the rice ecosystem
