    Bridging the gap: decomposing sources of gender yield gaps in Uganda groundnut production

    by Johnny Mugisha, Christopher Sebatta, Kai Mausch, Elizabeth Ahikiriza, David Kalule Okello, Esther M. Njuguna

    Female plot managers in Sub-Saharan Africa often realize significantly lower crop yields than their male counterparts. Even for legumes, which are often referred to as ‘women’s crops’, yields are significantly lower. This study investigated the underlying causes of this gender yield gap in groundnut production. The analysis is based on survey data from 228 farm households from two groundnut growing regions in Uganda. We used the Blinder-Oaxaca model to decompose factors that contribute to this yield gap. Results show 63% and 44% gender yield gaps for improved and local varieties, respectively, with female plot managers realizing less than their male counterparts. Improved groundnut seeds increase female plot manager’s yields but not the yields of male plot managers. Male advantage and female disadvantage combined account for more than 70% of the yield gap in both improved and local groundnut variety production and exceed pure productivity differences. Labor use differences between female and male plot managers and variety types explain the observed yield gap. Interventions and policies that increase women’s access to productive inputs including improved seed will significantly contribute to closing the yield gap, and thereby increase crop production, food security, as well as women’s incomes.

    Adding Value at the Farm: The Case of Smallholder Potato Farmers in the Highlands of Uganda

    by Christopher Sebatta, Johnny Mugisha, Enid Katungi, Apolo K. Kasharu, Harriet Kyomugisha

    This study set out to find out the profitability of engaging in activities that add value to the smallholder farmer’s potato produce after harvest so that it fetches a better price to improve on household income. The study was a survey where structured pre tested questionnaires were administered to potato farmers. Data were collected from 200 smallholder potato farmers in the highland districts of Kabale and Mbale in two potato growing seasons between December 2011 and August 2012. Thirty farmers were randomly selected from each of the two parishes in Wanale to give a sub-sample of 60 farmers from Mbale district. On the other hand, 35 farmers were randomly selected from each of the four parishes in Kabale district giving a total sub-sample of 140 farmers, and 60 farmers from Mbale district. Descriptive statistics, breakeven analysis and a bivariate probit model were used to analyse the data. Results indicated that 23% of all farmers had added value to seed potato while 88.5% had added value to table (ware potato). Kabale had a significantly higher number of farmers (P<0.01) adding value to seed potato than Mbale while the reverse was true for ware potato. Results of the break even analysis showed that value addition to both ware and seed potato at the farm was profitable with value adding farmers earning 40% more than those who did not add value. Bivariate probit results indicated that how much a farmer harvested influenced their decision to add value to ware potato while access to extension services significantly and positively influenced value addition to seed potato. Adding value to potato at the farm is therefore a profitable venture that can be used to increase household incomes according to these results.
