Water harvesting techniques were used for increasing water availability for rainfed agriculture and for human consumption. The treatments involving soil and water management for cropping were as follows: (1) traditional; (2) microcatchment; (3) microcatchment plus fertilization with ordinary superphosphate (OSP); (4) microcatchment plus fertilization with manure; and (5) supplemental tank irrigation. A cistern with 50 m3 capacity was construted to provide drinking water. The crop enterprises were cowpeas (Vigna unguiculata)/corn (zea mays), and sorghum (Sorghum bicolor)/cactus (Opuntia spp.)/algaroba (Prosopis juliflora). Both were intercropped. The overall objectives of the study were:(1) to examine the impact of the application of water harvesting techniquestogether with crop management, with and without fertilization on: (i) financial position of the farmer, (ii) profitability of each individual enterprise in cropping, and (iii) labor utilization; (2) to estimate the benefit of a cistern based on the costs of carrying water. All analysis were developed with the aid of Supercalc 4 spreadsheet software. Farm performance measures were: crop production; cash flows; income statements, net worth; cost and returns statements; and labor utilization. The impact of the household cistern was assessed through a benefit cost approach. From the results the following main conclusions were drawn: (1) microcatchment contributed marginally to increased yields; (2) microcatchment combined with OSP produced yield increasses which..
