Summary: The urban groundwater in the Quaternary aquifer of the Lake Chad basin in N'Djamena has been the subject of numerous hydrochemical studies, but the results are often not presented in a way that enables effective decision-making by water quality managers. This study aimed to contribute to improved management of local groundwater resources by evaluating water quality and its suitability for various uses. The research showed that the chemical composition of the groundwater is influenced by both geogenic and anthropogenic factors and their proximity to the Chari-Logone rivers, and highlighted the high spatial variability of groundwater quality in N'Djamena.

Summary: The assessment of groundwater recharge in the Lake Chad Basin, Africa's largest endorheic basin, is crucial due to its importance for both rural and urban water supply. By analyzing water chemistry, environmental stable isotopes, and carbon isotopes, the recharge processes and groundwater ages can be estimated. The results show that recent recharge occurs from precipitation in the north of Lake Chad, while focused recharge is observed in the Salamat Region and the Komadugu Yobe wetlands. Surface water undergoing evaporative processes is the main source of recharge along the Lake Chad shore and the Bahr el Ghazal corridor, and the groundwater ages in the latter area indicate residuals from the Mega Lake.

Summary: The Chari-Baguirmi region in Africa has a naturally occurring piezometric depression with deeper than expected groundwater levels. The lack of rainwater infiltration and exfiltration processes, past climate conditions, and geological structural constraints explain the origin and dynamics of this depressed area. Numerical simulations show that the rainfall effect is limited to upper soil layers, resulting in low aquifer recharge.

Summary: Yilong Lake, the southernmost plateau freshwater lake in China, has its watershed ecosystem with strategic significance for ecological security and sustainable development. This study analyzed the landscape types in Yilong Lake Basin from 1990 to 2018 and discussed the impact of landscape pattern changes on the ecosystem services values. The results show that the implementation of ecological protection and governance projects can increase the landscape types and total ecosystem services values.

Summary: This study aimed to understand the hydrological functioning of the Chari-Logone basin under the high variability of rainfall which has affected the Sahel region in the last sixty years. The results showed that the water flow in the basin represented only 5% of precipitation, with significant variations in flow during wet and dry periods, but no clear evidence of anthropogenic impact on flow or hydrological regime modification.

Summary: This study analyzed the change characteristics of landscape patterns in the Qinghai Lake Basin from 1990 to 2018 and predicted the changes in the period between 2026 and 2034. The results showed an expansion of grassland area and reduction of desert areas, with man-made factors playing a leading role. Government decision-making was deemed crucial. The simulation for 2018 to 2034 indicated little change in the proportion of various landscapes and stable spatial distribution, providing a reference for ecological environment management and protection policies in the Qinghai Lake Basin.

Summary: This study examines the ecological fragility of inland river basins in arid zones and the potential impact on ecological protection. It proposes a method for determining ecological source areas that considers landscape connectivity, using the Ebinur lake basin as a case study. The study also constructs an ecological security pattern, which can serve as a reference for the protection and restoration of the ecological environment in arid inland basins.

Summary: Governments are updating strategies to meet global goals on biodiversity, climate change, and food systems. Agroecology is a game-changing approach that can provide nutritious food, fair incomes to farmers, and halt environmental degradation. Enabling policy and market environments, participatory action research, and local socio-technical support are catalysts for agroecological transitions.

Summary: This study analyzed the relationship between the seed provisioning networks used by farmers to access crops and the different nature's contributions to people they receive from these crops, based on a case study in Sahelian Senegal. The study found that the seed sources used by farmers were related to the specific contributions provided by the crops, and women farmers relied on a more limited pool of seed sources compared to men.

Summary: Community seedbanks play a crucial role in conserving crop genetic diversity and supporting farmer seed systems. This study examines the seed flow and access to crop genetic diversity in three seedbanks in Uganda. The results show that the mode of operation and management of the seedbanks significantly influence the distribution and return of seeds. Furthermore, women exhibit higher engagement in returning seeds, except in one seedbank. Further research is recommended to explore these factors and identify the most effective strategies for seedbank effectiveness.
