Description Poverty, food insecurity, and malnutrition are pervasive in the serm-arid trOpICS (SAT)
of South Asia, including India. I n rural areas, most of the poor make their livelihoods
on the use of natural resources, which are degraded and inefficiently used. This is
because of the inadequate traditional management practIces of managing agriculture
as well as the fact that resulting crop yields are much below the expected potential
yields. ICRlSAT in the early 1970s initiated research on watersheds for integrated use
of land, water, and crop management technologies for increasmg crop production
through efficient use of natural resources, especially ramfal! that is highly variable in
the SAT and is the main cause of year-to-year variation in crop production ill India.
Improved watershed management on Vertisols more than doubled crop productivity,
and rainfall-use efficiency increased from 35% to 70% when compared wlth traditional
technology. After many years of implementmg and evaluating these improved
technologies in on-farm situations, many lessons were learned and they formed part
of the mtegrated watershed management model currently being pursued by ICRlSAT
in conununity watersheds in rural settings. This watershed model is more holistic and
puts rural communities and theIr collective actions at center stage for implementing
improved watershed technologies with technical backstopping and convergence
by consortium partners. We describe here the achievements made in enhancing crop
productivity and rainfall-use efficiency by implementing improved technologies in onfarm
community watersheds in India.
