The primary function of Soil & Water Conservation is enhancement of soil fertility, its productivity, regeneration of natural water resources and its Conservation for sustainable biomass production. The approach is watershed basis’ and the means to achieve is through Agronomy, Engineering and Forestry combined in an integrated manner.

 

Following are the important approaches being used for conservation of Soil and Water in Mizoram.

 

1. Terracing: This break length of the slope, reduces erosive force of run-off water, retain top soil materials, debris and run-off water on the terrace thereby enhancing soil fertility and soil moisture regime for sustainable production. The Soil & Water Conservation Department has constructed 708 ha. of terrace land during the first there years (2007-2010) against the 11th Five Year Plan target of 4,000 ha.

 

2. Water harvesting structures: These are done as strong tank / farm ponds across the small rives, on natural depressing in farm lands or at the convenient place in the farm for life saving irrigation to to crops in the lean season and for moisture conversation around the structures through seepage / percolation. During the first three years (2007-08 to 2009-10) of the 11th Five Year Plan Soil & Conservation Department has constructed 788 nos. of water harvesting structures against the target of 1700 nos.

 

3. Soil Conservation Engineering: It involves works like check dams, silt retention dam, drop structures, stream bank erosion control works along or across the small streams to retain silt, debris and flowing water for some time to provide more time for infiltration and percolation to improve ground water recharging. These structures also divert strong currents from damaging river banks adjoining to WRC areas. During the first three years (2007-08 to 2009-10) of the 11th Five Year Plan Soil & Conservation Department has constructed 310 of structures for Soil Conservation works against the target of 900.

River Valley Project / Flood Prone River::

 

29 nos. of projects is being implemented. Under these projects, Water harvesting, Terracing, Check-dam, Approach Road, Cash crop plantation had been taken up. During 2010-11, 339 structures covering an area of 2165 Ha. had been completed.
 

 

NLUP:

 

Under this Scheme, Rubber Plantation in the low lying area (less than 450m above msl) in Kolasib, Mamit, Aizawl, Lunglei Districts and Chakma Autonomous District Council on Cluster approach as far as possible will be done. Arabica Coffee Plantation will be done in middle portion of the State (1000-1500 ft above msl) and Broom grass plantation in marginal lands along National Highways and State High ways of the State.
