Land degradation is a severe environmental problem in the northern and northwestern Ethiopian highlands. As a response to increasing land degradation, rehabilitation of degraded grazing lands through exclosures (exclusion of farmers and domestic animals) has been undertaken. This study aimed to evaluate the effectiveness of 11 and 8-year exclosures in improving degraded landscapes in the Karita-Wuha and Dengora watersheds. It was assumed that the conditions on communal grazing lands at the time of the investigation corresponded to those at the establishment of exclosures.

Agriculture consumes the largest share of freshwater globally; therefore, distinguishing between rainfed and irrigated croplands is essential for agricultural water management and food security. In this study, a framework incorporating the Budyko model was used to differentiate between rainfed and irrigated cropland areas in Africa for eight remote sensing landcover products and a high-confidence cropland map (HCCM). The HCCM was generated for calibration and validation of the crop partitioning framework as an alternative to individual cropland masks which exhibit high disagreement.

Soil and water conservation have been traditionally part of farming practices for thousands of years. Despite massive efforts to implement modern soil and water conservation practices (SWCPs) in the Ethiopian Highlands, soil erosion increased after the 1970s when social and political events led to a remarkable change in land use. This review aims to critically analyze the impact of conservation practices on soil loss and crop yield and highlight research and modeling gaps.

There is a paucity of scientific information regarding gender norms and social transformation in the Sub-Saharan region. This has contributed to the insufficient articulation of gender issues in the proposed agricultural programmes and visions, such as the African Union’s Agenda 2063 and the Malabo Declaration. These efforts premise the transformation of the African continent on the foundation of the agricultural sector, a critical pillar in most countries in Sub-Saharan Africa.

Picture-Based Insurance is a new, innovative way of delivering affordable, comprehensive, and easy-to-understand crop insurance. By relying on visible crop characteristics derived from farmers’ own smartphone pictures, it aims to minimize the costs of loss verification and detect damage at the plot level, making crop insurance more attractive and accessible to small farmers.

Future climate models indicate an enhanced severity of regional drought and frequent rewetting events, which may cause cascading impacts on soil nitrogen cycle and nitrous oxide (N2O) emissions, but the underlying microbial mechanism remains largely unknown. Here we report an incubation study that examined the impacts of soil moisture status and nitrification inhibitor (DCD) on the N2O-producers and N2O-reducers following the application of urea and composted swine manure in an acid soil.

On 7 February 2024 at the InterContinental Cairo Semiramis, CGIAR Centers – Alliance of Bioversity International and CIAT, ICARDA, IWMI, IFPRI, and supported by the CGIAR Accelerate for Impact Platform (A4IP) – in collaboration with the Academy of Scientific Research and Technology of Egypt (ASRT) and under the auspices of the Ministry of Higher Education and Scientific Research of Egypt (MOHESR) hosted the "Consultation Workshop: Deep Diving into the Agri-tech Innovation Ecosystem in Egypt".

This study contributes to the observed reduction of arable lands discourse by examining the shift in land use patterns as well as factors influencing farmers' shift from crop production to mining activities. To achieve this, we employed a combination of Geographic Information System (GIS) technology and Cragg's Double Hurdle Econometric Model as analytical tools. Our approach integrates an econometric model of land use with GIS simulations that predict the spatial pattern of land-use change.

Le modèle Nexus « Gah Kêssê » est une approche holistique visant à améliorer localement les conditions de vie des populations agropastorales. Le modèle a été conçu, testé et analysé par la Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH pour le compte du Ministère Fédéral de la Coopération Economique et du Développement (BMZ) au sein du Projet global de la promotion d’une politique foncière responsable (ProPFR) et du module pays Bénin.
