Soil and Water Conservation Programmes of Agriculture Department in Himachal Pradesh
Soil and Water conservation is an integral component of Agriculture production in particular and environment protection programme in general. Himachal Pradesh is a hilly terrain with rolling topography and sloppy lands.The rain fall is high in rainy season which add the problems of soil and water conservation, where water scarcity is experienced in other seasons. Keeping in view, the importance of soil and water conservation, the Department of Agriculture is implementing rain water harvesting, soil conservation and soil erosion control schemes including Individual, Community based tank and Head weirs etc. under various schemes run by the Department to increase the agriculture production.
The detail of various measures adopted for soil and water conservation programme are as under:
A) Biological Measures :
Biological or vegetative measures are preferred in watershed development programmes as they are eco- friendly, sustainable and cost effective. These measures are normally adopted on lands milder slopes, less runoff and sediment flow.
Objectives
- To reduce splash erosion by moderating the impact of rain drops.
- To reduce runoff velocity and increase infiltration opportunity time
- To slow down wind speed .
- To trap fine soil and nutrients, and
- To improve physio-chemical properties of the soil and help in conserving moisture in low rainfall areas.
Types of Biological Measures:-
- Vegetative Barriers.
- Alley Cropping
- Ley Cropping
- Strip Cropping,
- Contour Farming
- Land Configurations.
- Tillage
- Mulching
- Residue Management.
B) Mechanical Measures:-
Where biological measures only are insufficient to check erosion to a desired level due to high velocity of run off or discharge , mechanical measures are needed. The mechanical measures not only check soil erosion but also conserve moisture for crop growth. Basically these measures constitute a series of mechanical barriers constructed across the slope to reduce or break the length of slope only or both the length and degree of slope to dissipate the energy of flowing water.The selection and suitability of engineering control measures to be adopted under different locations depend on soil depth, rainfall, land slope and crops to be raised.
•Bunding
•Terracing
•Leveling .
•Diversion drains.
•Contour Trenches.
•Stone Walls.
•Retaining Walls.
C) Drainage Line Treatment:-
Drainage line which carry runoff and sediment flow. They may have different forms such as drainage channels, gullies, natural / artificial waterways, streams, rivers or torrents.
Objectives:-
•Check soil erosion in the channel bed and adjoining lands.
•Improve moisture for biomass production.
•Protect banks/side slopes from undercutting or scouring.
•Recharge ground water.
•Flow guidance, bank protection and / or land reclamation in the downstream torrents.
Depending upon their location and objectives, the measures for drainage line treatment may be mainly grouped as :?Gully /Channel stabilization measures.
- Check Dams.
- Live Check Dams/ Vegetative Barriers. Temporary check dams.
- Permanent structures for gully stabilization /water harvesting.
- Drop Spillway
- Drop inlet spillway
- Torrent and stream bank erosion control measures.
- Spurs.
- Vegetative Retards.
- Protection / Toe walls
- Revetments.
D) Rainwater Harvesting Techniques:-
A. In situ Rainwater Harvesting :
1. Bunding and terracing
2. Vegetaive contour barriers.
3. Land leveling
4. Contour ditching.
5. Grades border strips
6. Contour farming.
7. Cover crops and mulching
8. Conservation tillage and deep ploughing
9. Contour trenching
B. Rainwater /Direct Surface Runoff Harvesting :
1. Rooftop Collection /rainwater cistern.
2. Dugout pond /storage tanks.
3. Diversion Bunds/ channel
4. Water spreading
C. Stream Flow or Runoff Harvesting:
1. Gully control structures/ check dams
2. Water harvesting dams / stop dams
3. Water diversions
4. Ponds
These schemes are taken up on the demand of local farming community/ public representatives and are based on feasibility reports counting various technical factors. These sanctioned schemes are then executed purely in participatory mode and as per RIDF ( Rural Infrastructure Development Fund ) guidelines( Guidelines stand approved by the Govt.) i.e. through Water Users Associations (WUA) by involving the beneficiaries of schemes.
Water users associations elect a Krishak Vikas Sangh (KVS) for each scheme and the same is registered under Societies Registration Act 2006. KVS execute these schemes under technical guidance of the Department. The operation and maintenance of the executed schemes is entrusted to the KrishakVikasSangh after its completion.

The projects would be completed during the 11th five year plan as per approval given by the funding agency i.e. NABARD under RIDF-XIV.
Conclusion :
Agriculture in Himachal Pradesh is a way of life for the agrarian population and nearly 70% population is directly or indirectly dependent on this sector. Presently, farming and farmers of Himachal Pradesh are passing through a transitional phase, state govt. has allocated 12 % of its plan resources for agriculture and allied sectors, which is highest in the country and also now state is promoting organic farming in a big way. Efforts are afoot to make Himachal Pradesh self sufficient in agriculture production and also improving the economy of the state.
