Abstract: | SUMMARY Long-term cropland fallowing decisions of farmers in the West Nile Province of Uganda were studied. Tabular and regression methods are used to examine the relationship between farm and household factors and seasons of net fallowing. The results show that farmers plan to decrease the rate of fallowing in the immediate future. Serious (but undocumented) problems in maintaining cropland productivity could result. Population density had a large and negative effect on net fallowing (seasons of fallowing less seasons of crops), decreasing from the current average of ?0.6 seasons to ?2.21 seasons for a doubling of population. This 268% decrease in the use of fallowing could occur in as few as 13.5 years, assuming a 3% annual population growth rate. Farms larger in size, but with no increase in per capita cropland availability, had a higher rate of net fallowing. Cashcrop production was negatively associated with net fallowing, whilst farmer age had a positive association. The results have implications for both agricultural policy and guidance for further research on cropland fallowing. Increased cash-cropping should not be recommended unless the full economic costs of using land resources are evaluated. Much of the increased area for cash-crop production would come from fallowed land, decreasing the rate of fallowing and thus increasing the potential for soil degradation. Fallowing has long been used in the area to maintain cropland productivity. Building upon farmers current practices and improving fallowing through the use of green manures and agroforestry could prove to be more economical than the use of mineral fertilizers. Investigating why farms larger in size and those with older head-of-households were able to use fallowing more effectively may provide key information for the development of more productive fallowing technologies. |
