Need assessment of project area:

Groundwater is the main source of irrigation in the Medak district. The increasing exploitation of groundwater during the last two decades and deficit in the rainfall for the last few years have driven the farmers to a distress situation, resulting in suicides in some cases. Increasing population with decrease in size of land holdings, increase in input cost, market fluctuations for agricultural produce, deepening of borewells / digging of new bore wells indiscriminately without any scientific advice, low quality of seeds, dependency of farmers on loans for agricultural inputs etc. and failure of monsoon since 1998 have led to a distress situation in the district.

Though the Manjira river is a perennial river, there are no major irrigation projects worth mentioning in the District. The other available surface water resources are large and small irrigation tanks numbering about 14,000. Out of the total cropped area of 5,25,000 ha., an area of 19,000 ha., (3.6%) is being irrigated by surface water sources and an area of 1,01,000 ha (19.2%) is being irrigated by groundwater, which indicates that groundwater plays a major role when compared to surface water. The various crops raised are rice, jowar, bajra, sugarcane, black gram, red gram, bengal gram, cotton, groundnut.

The average annual rainfall received in the Medak district is 873 mm. The cumulative departure of annual rainfall from normal indicates the extent of drought at a place. In the district, the cumulative departure of annual rainfall was categorized as ‘scanty’ ‘i..e., more than 60% below normal, in 33 mandals and ‘deficit’ i.e., below normal by 20% to 59% in 8 mandals. In the remaining four mandals, the rainfall was below normal by 0-20%. On an average, the district rainfall condition was ‘scanty’.

Due to scanty rainfall and ever increasing population, majority of the dug wells/dug-cum bore wells have gone dry. At present, maximum irrigation needs are met through bore wells. Bore wells of 102 mm are common in the District and utilized for domestic supply. The depth of these bore wells ranges between 20 to 45 m yielding 1.5 to 75cu.m/day. In weathered granite and alluvium, the transmissivity value ranges from 100 to 150sq.m/day and the specific capacity ranges from 0.005 to 0.16cu.m/m per unit cross-section.

OPTION B: SMART VILLAGE DEPLOYMENT SOLUTION TO MAKE VILLAGE CARBON NEGATIVE

Investment : Into solar for 180ha in the village farms with 150KW plant w/t inverters & pump = Rs 3,00,00,000

Cost Breakdown:

150KW solar plant would cost Rs 1,00,00,000.

10 core systems at 15 KW each = 10 X RS 1.50000 = Rs 15,00,000

Pumps of 5Hp (already installed) = 25,00,000

Returns: Agriculture generate annual revenues per hectare of about

Rs 6,50,000 X 180 = Rs 11,70,00,000

Extra Output Kg From Improved Irrigation in the Village= 241X180 = 43000 kg
