Summary: This article examines the role of water resources in conflict and how water availability and demand influence the likelihood of violent conflict, focusing on the Lake Chad Basin. The study combines hydrological and biophysical factors with socio-political processes to explore the potential for conflict. The findings highlight the complex interdependencies between water scarcity and violence, emphasizing the need for a comprehensive understanding of the socio-hydrological complexities.

Summary: The areal changes of Lake Chad have an impact on precipitation, with the shrinkage of the lake increasing rainfall in the afternoon over the lake basin. Reduced precipitation over a large lake is due to decreased convection caused by a shallow planetary boundary layer. Additionally, loss of Lake Chad and adjacent wetlands affects the local climate and circulation patterns.

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: Lake Chad, the fourth largest lake in Africa, has shrunk by nearly ninety percent since the 1960s, impacting food security and livelihoods for fifty million people in the Lake Chad Basin. This communication discusses how decreased rainfall, exacerbated by climate change, and human activity have contributed to the shrinking of the lake and recommends coordinated interventions to ensure food security needs are met for millions of people relying on the lake for sustenance.

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: The focus of this study is on the Lake Chad transboundary aquifer in Africa, with the development of a 3D groundwater flow model to understand hydrodynamics and estimate groundwater fluxes between countries. Results show groundwater fluxes between countries, but caution is needed due to limited data in certain regions. The study forecasts that changes in groundwater recharge rates are more sensitive to future impacts than changes in groundwater abstraction levels.

Summary: Long-distance migrants may synchronize their circannual clock according to the phenology of their environment during the breeding season, adjusting their migration timing based on conditions encountered at their breeding site the year before. Spring departure date is influenced by green-up date of the previous year, while arrival date at the breeding site is determined mainly by the latitude and longitude of the site.

Summary: This study developed and applied a new approach to calibrate hydrological models using distributed geospatial remote sensing data in the Lake Chad Basin in Africa. Through sensitivity analysis and optimization of influential parameters, the model performance was significantly improved. The new approach of using remote sensing ETa for a limited period of time showed robustness and good performance.

Summary: The study revealed the presence of different tsetse species and a diversity of trypanosomes pathogenic to livestock in the area of Lake Iro. The results highlight the risks and constraints that animal African trypanosomiasis pose to livestock breeding and the importance of assessing trypanosome infections in livestock in this area.

Summary: Fishing communities in Lake Chad are facing humanitarian crises with millions of people experiencing hunger and malnutrition. A study conducted on the Nigerian shores of Lake Chad provides insights from fishers themselves on the declining fish stocks and uses resilience theory to analyze their responses. The findings highlight the fishers' understanding of effective resilience strategies and the importance of their adaptive resilience and local knowledge in developing smarter fisheries management policies. The study calls for African governments to invest in and utilize local fisheries research to address the challenges faced by their fisheries.

Summary: Mixed alphabet codes are generalizations of classical linear codes over finite fields and rings. The letter introduces a method to construct FpR-additive codes, which are a combination of irreducible cyclic codes over F-p and trace codes over R. By using the Gray map, part of the obtained image codes meets the Greismer bound and can be used to construct new secret sharing schemes.
