One Hundred Priority Questions for the Development of Sustainable Food Systems in Sub-Saharan Africa

Sub-Saharan Africa is facing an expected doubling of human population and tripling of food demand over the next quarter century, posing a range of severe environmental, political, and socio-economic challenges. In some cases, key Sustainable Development Goals (SDGs) are in direct conflict, raising difficult policy and funding decisions, particularly in relation to trade-offs between food production, social inequality, and ecosystem health. In this study, we used a horizon-scanning approach to identify 100 practical or research-focused questions that, if answered, would have the greatest positive impact on addressing these trade-offs and ensuring future productivity and resilience of food-production systems across sub-Saharan Africa. Through direct canvassing of opinions, we obtained 1339 questions from 331 experts based in 55 countries. We then used online voting and participatory workshops to produce a final list of 100 questions divided into 12 thematic sections spanning topics from gender inequality to technological adoption and climate change. Using data on the background of respondents, we show that perspectives and priorities can vary, but they are largely consistent across different professional and geographical contexts. We hope these questions provide a template for establishing new research directions and prioritising funding decisions in sub-Saharan Africa

Determinants of Enterprises’ Use of Energy Efficient Technologies:Evidence from Urban Ethiopia

We conducted a cross-sectional survey of 8174 micro, small and medium enterprises from ten major urban areas in Ethiopia to study the determinants of the enterprises’ adoption of energy efficiency practices and technologies. For identification, we rely on a generalized ordered probit model. The findings reveal that, as the size of the enterprise becomes larger, it is more likely the enterprise will undertake energy efficient practices and technologies. This may be because larger enterprises are less likely to face constraints related to capital or know-how to adopt these technologies. Further, enterprises which are clustered in an industrial zone are also more likely to use energy efficient technologies, revealing a spillover effect of being located in the same place. Enterprises with highly educated entrepreneurs are in favor of the adoption of the technologies. By contrast, entrepreneurs who perceive pro-environmental activities as unnecessary and costly are less likely to use energy efficient technologies. Our results imply that expansion of industrial zones and educational (informational) campaigns are important for enhancing micro and small enterprises’ adoption of energy efficient technologies.The Environment for Development (EfD) initiative is an environmental economics program focused on international research collaboration, policy advice, and academic training.

Gender differences on the choices of a portfolio of climate change adaptation strategies in Ethiopia

Gender-based intra-household resource distributions constitute an important role in technology adoption-related decisions. Using a non-unitary household model and fitting an empirical adoption model for men and women individually and jointly, we examine how gender-based ownership, management and control of resources are correlated with adoptions of a portfolio of climate change adaptation strategies. Our analysis is based on recent household survey data with detailed household plot-level information about adaptation strategies, plot ownership, farm management decisions, and the right to control outputs from the plots among spouses within the household. The observed patterns of women’s ownership, management and economic rights of land suggest that all are important aspects of women’s bargaining power. We found compelling evidence regarding the overlapping effects of the different gender-linked-land-based rights on the adoption of a portfolio of adaptation strategies. The empirical findings emphasize the importance of incorporating gender-based intra-household interactions and joint resource ownership and decision making in climate change adaptation

Do Safety Net Transfers Improve Diets and Reduce Undernutrition? Evidence from Rural Ethiopia

<p><i>In this paper we examine the impact of the Ethiopia’s Productive Safety Net Program (PSNP) on household dietary diversity and child nutrition using both waves of the Ethiopian Socioeconomic Survey. For identification, we use various methodologies. Results indicate consistently that PSNP has not had the desired effect on household dietary diversity or child nutrition regardless of model specification or methodology, suggesting that perhaps the transfers need to be paired with additional interventions such as information about nutrition.</i></p

Spatial and temporal assessment of drought in the Northern highlands of Ethiopia

With the development of global changes, researchers from all over the world increasingly pay attention to drought detection, and severe droughts that may have resulted from climate change. In this paper, spatial and temporal variability of drought is evaluated based on precipitation data and remotely sensed images. The standard precipitation index (SPI) and vegetation condition index (VCI) are used to evaluate the spatial and temporal characteristics of meteorological and vegetative drought in Tigray, Northern Ethiopia. Based on the drought critical values of SPI and VCI defining drought, the spatial and temporal extent of droughts in the study area is established. We processed 396 decadal images in order to produce the multi-temporal VCI drought maps. The results of the SPI and VCI analysis reveal that the eastern and southern zones of the study region suffered a recurrent cycle of drought over the last decade. Results further show that there is a time lag between the period of the peak VCI and precipitation values obtained from the meteorological stations across the study area. A significant agreement was observed between VCI values with the current plus last two-months of precipitation. The study demonstrates the utility of the vegetation condition index in semi-arid and arid regions
