Abstract
Konanki mega watershed project was sanctioned in the year 2010-11 and implemented in Prakasam district
till March 2018. Impact study was conducted on environmental and socio-economic indicators by physical visit to the
project area and through bio-physical measurable characteristics by remote sensing and GIS techniques to assess
the outcomes and impact on the watershed community. The total geographical area of the project is 10,574 ha
having undulating terrain with net treatable area of 4,773 ha encompassing seven micro watersheds. The impact of
watershed management interventions were observed in terms of sustaining the productivity of crops under drought
conditions, development of waste lands and current fallow lands, increase in cultivated area, improvement in agrivegetation
and vigour, expansion of water bodies, soil moisture in the profile as a result of the effective in-situ soil
conservation and water conservation activities, increase in milk productivity,etc. The water productivity also found
improved through conservation measures and judicious use of available water resources. Watershed interventions
helped in enhancement of family income especially ofthe marginal farmers (37.1 % rise), small farmers (15% rise)
and landless poor (76.1% rise) of watershed community.
