years. So that benefit cost ratio comes 4.17 from indirect benefits for one year only. The cost of water conservation for RCCT is Rs.6.00/M3 comparing with percolation tank, Rs.25/ M3 and major irrigation project RS.35/ M3.There is no displacement of tribal, no water logging problem, no mosquito breeding site created, no pumping required, less water treatment require. This is decentralized water conservation technique. Considering the micro watershed, necessary treatment is applied. This removes root cause of soil erosion and depleting ground water levels. The production of grass in one hectare is approximately 2 to 3 MT/hectare costing Rs. 1000/MT and thinning operation gives firewood and other products of worth cost approximately Rs. 6400/hectare. Appreciation of land due to his woks increases in three fold because the no irrigated land gets converted into well irrigated land. Farmers are taking double season cash crops in place of single crop. ADVANTAGES 1. Barren land gets permanent biomass cover and soil protection 2. Soil loss in cultivable area becomes nil 3. Every drop of rain is held in situ 4. Augmentation of ground water without grouting 5. Good soil moisture and good ground water available in the wells, tube wells and tanks 6. Increase in life of dams, prevention of floods by avoiding silting 7. No displacement of communities or creation of environmental refugees and hence no rehabilitation costs 8. No migration of villagers to cities as the local water availability ensures livelihood sustainability 9. Decentralized and democratic water management 10. Evaporation losses are negligible as compared to tanks and dams 11. No separate nullah bunding, gully plugging and such other civil structures 12. Accelerates soil formation and natural succession dramatically 13. Increases fodder resources for feeding cattle and livestock 336 14. Increased agricultural and biomass production 15. Guaranteed mass employment generation to rural people at their doorstep 16. Land value increases significantly 17. Increases crop intensity and biodiversity 18. Women free from the drudgery of finding and fetching water, fuel and fodder from distant places 19. Clean water for drinking purposes. DISADVANTAGES : 1. Very tedious and laborious for alignment 2. Time consuming 3. Requirement of accuracy skilled labours and instruments like contour marker. 4. There is potential danger of water flowing along the upper edge in case the trench breaks. CASE STUDY : Dolasane, Tal. Sangamner, Dist. Ahmednagar (Maharashtra) India Dolasane village has an forest area of 524.40 ha. Total 145 ha. Area was treated with RCCT method. The impact of RCCT work on village has been clearly indicated; • Agriculture: yield per acre increased from 50 kg to 500 kg per acre of bajra and wheat. • Irrigation : 95% agriculture is rainfed has changed to well irrigated due to increase in water level of wells. • Grazing :cattle population is reduced from 6358 to 1115 with increase in milk production. • Control of soil erosion & flash floods • Income generation: farmers with four acre land can make a profit of Rs. One lakh minimum per year.
