We all know that water is precious and with growing population and their needs, fresh water is getting even more worth full with each passing day.Main uses of fresh water are drinking,washing and in Agriculture.Each year irrigation requires large amount of water and one of the main source of this water is rain. This makes rain water harvesting a top priority for farmers in every country from east to west.
Why we need farm ponds?
Most of the farmers all around the world heavily depends upon rain for their agricultural needs.Crops are very sensitive and two or three delays of watering can have devastating impact on crop production. Farm ponds help them to become somewhat independent and they can timely give water to their crop irrespective of time of rain.It also helps to improve ground water significantly.Farms ponds with drip irrigation would play great role in water management.
Water saved here can be used somewhere else ex. industries, households etc.
Less dependence on ground water which eventually increase it.
More production,less price of food grains for poor.
More area can be covered in agriculture where due to lack of water resources farming is almost impossible.
How it can be done?
It can be done using Farm Ponds. Farm ponds are artificial ponds dig inside the farm to harvest rain water.
Construction of Farm Pond Manually( Example):
Top Cross section of Pond = 27 m * 27 m
Bottom cross section of Pond = 23 m * 23 m
Depth of Pond = 3 m
Side slope = 1 :1
