Chapter 11 (Page no: 197)

Opportunities for water harvesting and supplemental irrigation for improving rainfed agriculture in semi-arid areas.

This chapter discusses the research results and experiences gained in runoff harvesting and supplemental irrigation in the semiarid tropical (SAT) regions of India and Africa. Topics covered include: traditional tank irrigation in SAT India; assessment of adequate water availability in tanks at critical crop growth stages; optimum tank size and other design parameters; efficient application of supplemental irrigation water; crop responses to supplemental irrigation; economic evaluation of runoff storage structures and supplemental irrigation; and watershed-based water harvesting, groundwater recharging and efficient water utilization.
