Determinants of household water and energy access and their impacts on food security and health outcomes in Sudan

Determinants of household water and energy access and their impacts on food security and health outcomes in Sudan

This study investigates the determinants of access to safe water and reliable energy for households in Sudan using nationally representative data from a recent labor market survey. The results show that urbanization, education, and wealth significantly enhance the access households have to these essential services, while rural areas and less developed regions, particularly in the Darfur and Kordofan regions, face substantial challenges. Access to reliable energy correlates with better food security and health outcomes within households, and improved access to safe water significantly enhances the health of household members. Policy recommendations supported by these research results include targeted rural infrastructure investments, educational improvements, and regional interventions to address disparities in household access to safe water and reliable energy across Sudan.

Tajikistan’s agrifood system structure

2025Khakimov, Parviz; Diao, Xinshen; Goibov, Manuchehr; Ashurov, Timur

Tajikistan’s agrifood system structure

Tajikistan’s agrifood system (AFS) accounted for 34.7 percent of Tajikistan’s national GDP and 58 percent of employment in 2022. Primary agriculture alone contributed one-quarter of total GDP and 54.9 percent of employment, while the four off-farm components of the AFS contributed about 10 percent of GDP and 3.2 percent of employment. The share of employment in primary agriculture in total employment in AFS (AgEmp+) is huge, 94 percent. The off-farm components of the AFS therefore accounted for close to 30 percent of AgGDP+ and only 5 percent of AgEMP+. Though Tajikistan is an agrarian economy, it imports a lot of foods, and the shares of imports in the country’s total merchandise imports are consistently high, around 22 percent between 2016 and 2022. For the same period, food exports as a percentage of total merchandise exports were just 3 percent (World Bank 2023). Agrifood imports also grew more rapidly, increasing by a multiple of 16 between 2000 and 2023, while exports only doubled over the same period (Khakimov, et al. 2024).

Climate change and the impact on taro in Papua New Guinea

Climate change and the impact on taro in Papua New Guinea

In this paper we present a brief summary of recent historical climate of Papua New Guinea (PNG), finding that rainfall has been increasing greatly compared to pre-1995 levels, but that temperature has only been rising at a moderate rate. We then examine the 5 climate models used in this study from the Inter-governmental Panel on Climate Change (IPCC) / ISIMIP / CMIP3b, discovering one – IPSL – which best reflects the climate trends noted in PNG since 1995. The climate model projections show that temperature changes in PNG are expected to be less than most other places in the world and precipitation changes in PNG are projected to be higher than most other places in the world. Despite noting that IPSL seems to best represent climate changes observed thus far, we use all 5 climate models in the DSSAT crop model for taro, investigating how each climate model will lead to changes in taro yields at each half-degree pixel. In the aggregate, we find that the IPSL model leads to the greatest projected reduction in taro yield at -6.4% for the nation, with Southern region projected to have greater than 10% yield reduction for taro. Across the 5 climate models, the median across model results suggest only a 1.6% yield reduction, while the most optimistic model projects a 4.4% gain. Because of uncertainty across climate models and different impacts across regions, as well as potentially increasing climate variability which would lead to more extreme events including droughts and floods, we recommend developing a suite of options to help farmers navigate future climate uncertainty. For example, developing and testing crop varieties that would offer better yields whether the future is wetter or drier, as well as varieties that are less sensitive to temperature extremes. These could include new varieties of taro but might also include alternative crops and farming techniques designed to protect the plants during ad-verse climate events.
