Toward integrated dam assessment: Evaluating multi-dimensional impacts of the Grand Ethiopian Renaissance Dam on Sudan

The Grand Ethiopian Renaissance Dam (GERD) on the Nile is expected to influence many ecosystem services, such as flood regulation, hydro-electricity production, food supply, and habitat provision, among others. Understanding these impacts (positive and negative) requires a comprehensive evaluation framework. This study develops and applies an integrated simulation framework for assessing the impacts of the GERD on Sudan, focusing on the simultaneous economywide effects of riverine flood hazards, irrigation water supply, hydropower generation, and floodplain-dependent industries, namely traditional fired clay brick production. The simulation framework incorporates three models: a river infrastructure system model, a flood model, and a Computable General Equilibrium Model. Results indicate positive impacts for hydropower generation and flood control, marginal benefits for water supply to existing irrigation, and negative consequences for brick production and the construction sector. Assuming that the GERD starts its long-term operation in 2025, we find an overall positive economic impact on Sudan’s Gross Domestic Product in 2025, with an increase of up to just over 0.1%, subject to river flow conditions. Recognizing the differences in impacts across sectors and income groups, the study emphasizes the need for interventions that ameliorate negative effects. While the study captures several impacts, other effects on the environment, recession agriculture, and soil fertility require further investigation. Still, our findings underscore the importance of adopting an integrated simulation approach to dam evaluation, acknowledging the interconnected nature of water and related sectors in national economies.

Sustainable livestock development in Sudan: Challenges, opportunities, and policy priorities

Livestock in Sudan plays a crucial role in the national economy, particularly in alleviating poverty and enhancing food security. Despite its significance, the last comprehensive livestock census for the country was conducted in 1975, resulting in now outdated and often unreliable data. Recent estimates by USAID indicate that Sudan ranks among the top three African countries in terms of livestock numbers, with an estimated 105.6 million animals. The livestock population in Sudan is predominantly composed of camels, goats, sheep, and cattle. The spatial distribution of livestock is variable and influenced by local factors such as feed resources, land use, and ecological conditions. The Greater Kordofan and Greater Darfur regions have the largest livestock numbers. However, discrepancies between official statistics and field data show the need for updated and accurate livestock data. The livestock sector provides 40 percent of employment and 34 percent of Sudan’s agricultural gross domestic product (GDP). The livestock sector is a vital source of foreign exchange for the Sudanese economy through exports of livestock and livestock products. Besides its economic contributions, the livestock sector provides essential food products, including meat, eggs, and milk, and draught power for agricultural operations and transportation, particularly in rural areas. However, relative to irrigated agriculture, the sector faces challenges due to underinvestment and minimal government attention.
