Semi-arid lands typically receive between 300 mm and 750 mm of precipitation. Rainfall is sporadic and usually less than 30 rainy days. When a downpour occurs, which is more than 30 mm, surface runoff needs to be captured. This can then be used as supplementary irrigation when rainfall fails to occur over more than 7 to 10 days, and the crops need lifeline water. By incorporating a rabbit hutch and a chicken coop, the droppings are used to rear fish in the farm pond. The water, too, has richer nutrients for the land when applied – truly fertigation. This is being demonstrated in the GKVK-University of Agricultural Sciences campus in Bangalore, India.
