Water and Soil Conservation

 

Environment and Soil Conservation

m38desiltingMarathwada is well-known for drought prone area. Manavlok implements several activities in hundreds villages to minimize the problems of people due to drought.

In the very early financial year of 2002-2003, Rural Development Ministry, Govt. of India had selected Manavlok as implementing organization for District level Monitoring Program to monitor rural development schemes in five districts (i.e. Beed, Latur, Hingoli, Gadchiroli and Yavatmal) of Maharashtra.

Distilling And Pouring Slit:

m39For this  activity we have to follow basic steps as:

  1. Desilting the dry water bodies & lifting silt had been done by JCB.
  2. Transportation & Pouring Silt on farmers land had been done by Tractor,
  3. Farmers themselves spread the silt on their farms. The impact will be accessible or visible on both desilted water bodies and silt poured farm after six months.

This activity was attracted by farmers, especially by the dry land or barren land holding farmers because wherever the silt is poured they don’t need to use fertilizer. Also it agriculture products came out as organic products. As per our impact assessments on  the activity- there are remarkable outcomes of pouring of silt on the dry land farm; Production of farm without pouring silt yield 1 quintal approximate per acre and  Production of farm with pouring silt yield 3 quintals per acre . And desilted water bodies have become more water storage capacity and increase in water percolation capacity which has lot of positive impacts in the vicinity.

 
m37This activity is performed to enhance the water accumulating capacity of a dry water body. This not only helps in enhancing the water accumulating capacity of the particular water body but also make available large amount of silt which is considered to be the best natural  manure for the agriculture.It helps in increasing crop yield. The excavated silt is made available to the farmers to pour it on their land by paying only transportation charges. With five sites during draught period, we have excavated around 297766 Cubic meters silt from dry water bodies, which has increased water accumulating capacity to 29,77,66,000 liters.Here one trip of silt means a quantity of 3 cubic meters of silt. It required 50 trips (150 cubic meters) to fill one acre of land. The Table depicted that there are 1077 trips of silt has been given to 108 farmers from 6 villages.

Water Accumulating Deep Trenches (WADTs):

This Program is a continuous replication activity of our success method or experiment on prevention of Water Scarcity in drought-prone areas. In every village there are 2-3 streams or rivulets or brooks or rivers. The excessive rain water from land or village comes to brooks or streams or rivulets and ultimately flows to rivers. At the same time it carries soil also.  Rain water in the brooks or rivulets or streams or rivers accumulates in the Dug WADTs and percolates underground. This certainly benefit the wells (dug wells) in the vicinity. The size of the WADTs varies according to the landscape or structure of the streams or rivulets or brooks or rivers. The size of WADT for small brook can be 5m*3m*2m, dig at regular or irregular distance in the brooks or rivulets or streams or rivers. The water storage capacity in a WADT of 30 Cubic meters sizes is 30000 litres at one time filled. In a year it fills minimum 5 times; which means rainwater percolated underground minimum 150000 litres in a WADTs of 30 Cubic meters size.

As per our past impact assessment of the activity, the outcomes were:

  1. Prevent the soils to reach to river or dams during rains,
  2. The soil accumulated in the pit and farmers using the soil as manure,
  3. The accumulated water were percolated underground that prevent evaporation.

Thus the wells in the vicinity produces more water even in the period of delayed rains for Kharif and Rabi crops.

This year too we dug WADTs at Eight villages under two Districts (Beed and Osmanabad) of Maharashtra where are the drought most affected villages/areas. WADTs were dug at different sizes but we calculated 30 Cubic meters pit is equal to one WADT for the conveniences of accounting and impact assessments. The Table depicted that there are 145 WADTs in 8 villages shared by 104 farmers. These 145 WADTs will be storing minimum 21750000 litres of water every year.

m41wadtThis activity is for awareness among villagers in drought prone area about preservation of water and improves the situation of water.  We implemented this program on public buildings like schools and temples where it is visible by public.

This year we installed RWH at three different educational institution namely:

  1. Shri Sane Guruji Vidyalaya – Bhavthana Village,
  2. Krantisingh Nanasaheb Patil – Yelda Village, and
  3. Manavlok College of Social Science – Ambajogai.

As a method of rainwater harvesting to improve the scarcity of water we put Tin Curb Water Filter Lock at the edge of the roof and connected to wells with plastic pipes. The total area covered of Roof Water Harvesting is 925 Running Feet.

The impact of this activity is seen in the wells and water hand-pumps of the vicinity. The result is very encouraging; after one Inch Rainfall, the bore well in the school and well in the vicinity started yielding water.
