Résumé
A major problem facing Botswana, with its semi-arid climate, has been the provision of viable employment opportunities for the majority of the population that live in rural areas. In 1981, the remote area of Western Ngamiland was selected as the site for an integrated programme of development with the dual objective of creating employment and increasing production. The farming systems research approach was implemented to meet these goals for arable agriculture. Its methodology is discussed and the results put into the overall development perspective for the area. Two farming systems were investigated. Molapo agriculture, practised by the Bayei Tribe, utilises the floodwaters of the Okavango Delta in the seasonally inundated areas to overcome the main constraint to crop production, the lack of moisture. Changes in the flood regime were found to have reduced the area of wet cultivable land. In response, farmers had shifted their fields in search of moisture, but problems of land preparation led to the establishment of poor maize stands. Improved land preparation methods were tested in conjunction with row planting to facilitate the weeding of crops. Other problems were the encroachment of livestock on the widely dispersed fields and the effective control of weeds early in the season.
