Determinants of crop abandonment by smallholder maize farmers in Zambia

Abstract

Crop abandonment is when farmers decide not to harvest their previously planted crop. There is limited but emerging literature on crop abandonment or failure predominantly examining weather and crop failure rates. Consistent with these existing scant studies, it is not immediately clear to what extent historical relationships can be extrapolated in the long run under climate change. This paper seeks to improve our understanding of determinants of crop abandonment decisions in Zambia for maize production at subnational level. We find that crop abandonment (harvesting) is positively (negatively) related to fertiliser use, rainfall and temperature and negatively (positively) related to cost of living, price of maize, index-based insurance cover, town and random shocks. Therefore, fertiliser, rainfall and temperature increase the likelihood of crop abandonment in Zambia whereas increasing cost of living, maize price, insurance participation, town specific and random shock reduce it.
