           The Department of Soil Survey & Soil Conservation is playing a lead role in catering to the soil and water conservation requirements of the State and serves as the information hub for scientific and reliable information on soil and land resources and formulates and implement various soil and water conservation projects by optimizing the natural resource utilization by adopting scientific land use as per land capability for ensuring soil health. The soil and land resource inventory of each area carried out by the Department will provide necessary scientific data for adopting suitable soil and water conservation measures for each microenvironment to prevent soil erosion, to bolster the ground water recharge and to invigorate the agricultural sector by enhancing the soil fertility status and the ultimate aim is augmentation of agricultural productivity. The creation and updation of the scientific database on soil and land resources through various kinds of Soil Surveys and formulation and execution of developmental programmes at micro and macro level is one of the major mandate of the department.

                 The Department of Soil Survey & Soil Conservation has been involved in the formulation & implementation of various Soil and Water Conservation Programmes since first plan period. Controlling run-off to minimize silt yield from unit land and promoting in situ moisture conservation for ground water recharge are the basic propel of any soil and water conservation programme. Thrust is given for undertaking projects which result in the improvement of the microecosystem in terms of ecological, meteorological, agricultural, environmental and social aspects concerned.

 This Organization upholds "Watershed Approach" for realizing the perspective of sustainable and holistic development. The major thrust areas in implementing various soil and water conservation programmes include

Ø   Conservation of soil and water resources on watershed basis with a view to sustain Agricultural Production and to rejuvenate the ecosystem. Promotion and propagation of eco-friendly and cost effective conservation measures adopting watershed principles.

Ø   To develop suitable strategies for rainfed farming by adopting rainwater harvesting through participation of the people and people’s representatives for potential development of watersheds and promotion of farming system approach for augmenting the income of farming communities.

Ø   To prevent Soil erosion and runoff from the watershed with a view to prevent premature siltation of multipurpose reservoirs and also to reduce flood peaks and volumes of runoff.

Ø   Check the silting up of natural water bodies, drainage courses, reservoirs, paddy fields etc.

Ø   Stabilize and develop land slide/slide prone areas.

Ø   Generate rural employment on a regular basis as a result of the soil and water conservation projects implementing throughout the state thereby enhancing the socio-economic status of the people of that locality.
