In tropical country such as India which experiences more variation on rainfall, both in space and time, rainwater management assumes vital importance in cutting down risks optimizing crop production in dryland. Climate and soil are the two dominant factors in deciding whether or not runoff farming / water harvesting system will be possible and sensible. The hyper arid zone (P/PET<0.03) is too dry for viable runoff farming , while sub humid zone (P/PET=0.5-0.75) will be too wet The runoff farming zone is primarily situated in the arid zone (P/PET= 0.03- 0.2) and ...
