a) Name of the intervention introduction of rice based cropping system through medium land created by land shaping, water harvesting
through pond excavation. Farmer name: Bimal Mridha, village- Tushkhali, Sandeshkhali-II. Without intervention: cross checked with same intervention,without land shaping in low land in the adjacent field. Farmer name:

E&S framework developed and implemented?
Environmental framework developed and implemented
Positive benefits Negative effects Mitigation measures
Reduction of land for crop cultivation due to land shaping
Harvested rain water helped alternate use of land for pisciculture and brought additional area under cultivation and improve quality of degraded soil and water.
Improved water quality due to rainwater harvesting
Displacement of fertile top soil
The top soil reinstated by keeping it aside while making the land shaping; suitable management practices undertaken to improve fertility of top soil.
Environmental framework developed and implementd
Positive benefits
Negative effects
Mitigation measures
Affecting soil health for introducing HYVs, crop diversification
Use of INM and IPM practices.
Stress on water due to change in cropping patterns
Rain water harvesting ensures additional good quality irrigation water for minimizing stress
Less animal diseases for good health care and improved feed
Social framework developed and implemented
Positive benefits
Negative effects
Mitigation measures
Improving productivity through land shaping, creating WHSs, proper land management etc.
High cost involved in land shaping and also loss of arable land into low lying area.
The profitability of growing crops to cover the cost including initial investment would be ensured through selection of high value and low water requiring crops.
Enhancement of income through introduction of HYV, crop diversification, fish farming (fresh & brackish water), paddy cum fish culture, improvement of health care and feed of livestock
