Spatial Integration of Maize Markets in Post-liberalised Uganda

Abstract: "Using weekly price data for two sub-periods, this paper analyzes how Ugandan maize market performed in the years following agricultural market liberalization in the early 1990's. For each time period, the extent of integration, causality among spatial locations, and relative importance of spatial locations in price formation are examined. The extent of integration, defined as a set of markets that shares common long-run price information, and the causal relationships among markets have been tested within Johansen's cointegration framework. The relative importance of each market locations is examined by estimating the common trend coefficients with a dynamic vector moving average model. Results indicate that, while there has been an overall improvement in spatial price responsiveness, the northern districts, which have been in a state of insurgency since 1986, continue to lack integration with major consumption markets in the central region. Causality test results show that compared to the 1993-1994-time period, representing the early years of liberalization, interdependence among markets has increased. Estimates of the common integrating trend suggest that public policies, such as price stabilization, can have desired impacts by targeting a small number of locations. These results are consistent with recently conducted household and market surveys in the country." Author's Abstract

Educational and health impacts of two school feeding schemes : evidence from a randomized trial in rural Burkina Faso

Abstract: This paper uses a prospective randomized trial to assess the impact of two school feeding schemes on health and education outcomes for children from low-income households in northern rural Burkina Faso. The two school feeding programs under consideration are, on the one hand, school meals where students are provided with lunch each school day, and, on the other hand, take-home rations that provide girls with 10 kg of cereal flour each month, conditional on 90 percent attendance rate. After running for one academic year, both programs increased girls’ enrollment by 5 to 6 percentage points. While there was no observable significant impact on raw scores in mathematics, the time-adjusted scores in mathematics improved slightly for girls. The interventions caused absenteeism to increase in households that were low in child labor supply while absenteeism decreased for households that had a relatively large child labor supply, consistent with the labor constraints. Finally, for younger siblings of beneficiaries, aged between 12 and 60 months, take-home rations have increased weight-for-age by .38 standard deviations and weight-for-height by .33 standard deviations. In contrast, school meals did not have any significant impact on the nutrition of younger children.

Soil-type influences human selenium status and underlies widespread selenium deficiency risks in Malawi.

Abstract: Selenium (Se) is an essential human micronutrient with critical roles in immune functioning and antioxidant defence. Estimates of dietary Se intakes and status are scarce for Africa although crop surveys indicate deficiency is probably widespread in Malawi. Here we show that Se deficiency is likely endemic in Malawi based on the Se status of adults consuming food from contrasting soil types. These data are consistent with food balance sheets and composition tables revealing that >80% of the Malawi population is at risk of dietary Se inadequacy. Risk of dietary Se inadequacy is >60% in seven other countries in Southern Africa, and 22% across Africa as a whole. Given that most Malawi soils cannot supply sufficient Se to crops for adequate human nutrition, the cost and benefits of interventions to alleviate Se deficiency should be determined; for example, Se-enriched nitrogen fertilisers could be adopted as in Finland.

The Impact of Agricultural Extension Services in the Context of a Heavily Subsidized Input System: The Case of Malawi

Abstract: This paper aims to test this hypothesis and to contribute to better understanding of strategies to revitalize the agricultural extension system in Malawi. Specifically, it examines the interplay between the fertilizer subsidy and access to extension services, and their impact on farm productivity and food security in Malawi. Results show that the fertilizer subsidy has inconsistent impact on farm productivity and food security; at the same time, access to agricultural advice was consistently insignificant in explaining farm productivity and food security. Further analysis, however, shows that when access to extension services is unpacked to include indicators of usefulness and farmers’ satisfaction, these indicators were statistically significant. Households who reported that they received very useful agricultural advice had greater productivity and greater food security than those who reported receiving advice that they considered not useful. This result implies the need to ensure the provision of relevant and useful agricultural advice to increase the likelihood of achieving agricultural development outcomes.
