Adaptive Climate Change Measure: Water Harvesting

Adaptive Climate Change Measure: Water Harvesting

Climate change is becoming more real now than before, and its impact on agriculture is very alarming. Many farmers are seeking ways to mitigate its impact on their farming activities and, thus water harvesting becomes an option.



Water harvesting is a method of getting and storing water from different sources for the purpose of irrigation. It is also known as water recycling. The harvested water are mainly from rainfall and nearby river, which is utilized for crop production during the dry season period.


One of the advantages of water harvesting is that it's cost effective compare to well or borehole system. Also, it requires simple technology of diverting all rainwater or river to reservoir/ channels. The reservoirs could be storage tanks or excavated earth (in form of ponds). However when using the earthen method, it is advisable to treat water before applying to crops in order to mitigate risk of disease infestation. For optimization, the pond could be used to rear fishes especially Tilapia. This is another source of revenue to the farmers.
