Abstract
We investigate the patterns and determinants of subsistence acreage diversity in Botswana for the period 1978/79-2013/14, focusing on the role of input subsidies. Results suggest that acreage diversity declined during 1978/79-1987/88, due to increasing concentration on the dominant crop of sorghum. However, acreage diversity rose during 1987/88-2006/07, owing to falling concentration on sorghum production. Acreage diversity then fell again during 2006/07-2013/14 because of increasing concentration on maize, which had by then become a dominant crop. We found increased rainfall in the current year to yield a decline in acreage diversity in the current year, as farmers increased maize (a riskier crop climate-wise) acreage share, and reduced beans/pulses (a less risky crop) acreage shares. However, increased rainfall in the current year causes risk-averse farmers to reduce sorghum (a drought tolerant crop) acreage share and to increase maize, beans/pulses and groundnuts acreage shares in a subsequent year. The ISPAAD input subsidy program has yielded reduced acreage diversity, due to its negative impact on maize and beans/pulses acreage shares. Such unintended effects imply that ISPAAD has conflicted with the national objective of promoting agricultural diversification.
