Water harvesting
is a broad term covering the various techniques
to collect rainwater from natural terrains
or modified areas and concentrating it for
use on smaller sites or cultivated fields
to assure economic crop yields. This is basically
designed to provide supplemental or life saving
irrigation to crops, especially during the
periods of moisture stress. Dry land orchard
crops, mulberry and vegetable crops can be
grown for higher income and more sustainability
in production. For efficient application of
irrigation water, it is feasible to adopt
either sprinkler or drip irrigation methods
so that extensive area could be brought under
irrigation for the same quantity of water.
Farm ponds also greatly help in sediment collection,
which contain valuable plant nutrients. The
collected silt could be best used as a source
of plant nutrient to the crops grown in dry
lands. This kind of nutrients harvesting for
re use for crop production is useful when
the rainfall intensity is very high causing
sufficient runoff for storage, erratic seasonal
distribution of rains resulting in long dry
spells and to raise the high value long duration
crops with protective irrigation. The water
can also be harvested to recharge the ground
water through the percolation ponds in a sequence
on drainage line. |

Objectives
of Watershed management |
|
| |
| 1. |
Conservation,
development and utilization of Natural
Resources like soil and water for
Sustainable Agricultural Production. |
|
|
| |
| 2. |
To
generate additional income and employment
for the people in the area. |
|
|
| |
| 3. |
To
improve the environmental conditions
of the area. |

Our
approach |
|
| |
| 1. |
Active
involvement of farmers in the project
with marginal contribution of expenses |
|
|
| |
| 2. |
Supplementation
of technical know how, training, submission
of projects to obtain grants from various
public agencies and also take part in
expenditure of the project by Godavari Biorefineries Ltd. |
|
|
| |
| 3. |
Motivate
Govt. agencies to participate in this
programmme. |
|

With these
point into consideration Godavari Biorefineries Ltd.
,Sameerwadi has identified a catchment area
covering around 3500 acres from Sultanapur
and Handigund villages .Based on the information
collected beneficiaries have been identified
and then after through interaction with them
there were series of training programmes involving
various facets of watershed program. Subsequently
entire survey was carried out and based on
the technical feasibility the sites of check
dams were fixed and work was initiated and
completed. |

with
officials of Godavari Biorefineries Ltd., Sameerwadi
|
|
Further,
after completion of above work trainings
were given regarding the use of the
water effectively and about the growing
of different Horticultural crops on
the bunds and wastelands along with
the sugarcane plantation. To facilitate
the same arrangements to supply the
different horticultural crops like Mango,
Sapota, Guava and Teak plants to the
farmers of the catchment area. Meanwhile
we are also taking the dimensions of
surrounding well and bore wells like
length width and depth with an objective
of estimating the ground water recharge
by taking observations of selected wells
and bore wells with a frequency of three
months.
