    Water provides different goods and services like handcraft and fishing materials, water supply for domestic use, businesses, agriculture, transport, washing, drinking, and eco-tourism. However, few studies have assessed the effects of climate change on water resources in recent years. This study investigated the relationship between water resources and climate change in Sub-Saharan Africa. In the first segment, Vos-Viewer was used to map, study the literature, and identify any gaps to evaluate the interdependence between water resources and climate. The study was guided by specific objectives, which include assessing the adaptation and mitigation strategies for the effects of climate on water resources. Searches for the keywords “climate change” and “water resources” were conducted to obtain literature for this study. A total of 125 papers selected for this study from 1945–2022, from Scopus, Google Scholar, Science Direct, and Web of Science, were found relevant for this study and were selected and discussed. Thus, the worldwide literature was used to provide a real understanding of the effects of climate change on water resources, adaptation, and mitigation measures. According to the findings of the study, cooperation networks in developing countries were not as prominent as research networks in developed countries. It was shown that irregular rainfall affects water quality and quantity by giving the water a muddy, acidic, and turbid appearance. Therefore, all stakeholders should facilitate prudent water resource usage by 695 million people who still use unimproved water facilities in sub-Saharan Africa.

    Mapping of land degradation using spectral angle mapper approach (SAM): the case of Inaouene watershed (Northeast Morocco)
    (Springer Nature Switzerla, 2023-04-26) Benzougagh, Brahim; Meshram, Sarita Gajbhiye; Fellah, Bouchta El; Mastere, Mohamed; Basri, Mohamed El; Ouchen, Ibrahim; Sadkaoui, Driss; Bammou, Youssef; Moutaoikil, Nassima; Turyasingura, Benson
    Soil erosion is one of the most critical hazards adversely afecting both environment and economy for all countries in the world. Several regions of Morocco sufer from the problem of soil erosion, notably the Rif and the Pre-Rif where the study area of this paper is located. The spectacular expansion of soil erosion processes in the Lahdar watershed is a worrying indicator of soil degradation. Geographic information systems and remote sensing are an excellent tool for analyzing and evaluating the risks of the expansion of soil degradation. The main objective of this paper is to assess spectral angle mapper (SAM) method and analyze their properties using geographic information system and image processing techniques in order to map the hazards of soil erosion. Land use and land cover dynamics demonstrate the relationship between human-induced development and the evolution of soil degradation and biodiversity conservation in a watershed. Therefore, an understanding of LULC factors is required for the implementation of environmental policies intended to foster a synergy between humans and the sustainability of their environment. The process of categorizing LULC was completed using the SAM technique, and the role of LULC in the dynamics of soil degradation was investigated using measurements of landscape fragmentation. For this purpose, Landsat 8 Operational Land Imager data (11 bands) with 30-m spatial resolution, 22 August –2017 were used, and classifers for SAM were applied and evaluated. The fndings of the study are seven main land cover categories: arboriculture (0.08%), cereal (35.05%), water (1.03%), forests (3.76%), residentials (4.61%), matorral-course (4.58%), and bare soils (50.89%). It should be noted that the bare soil class occupies half of the watershed area, making it vulnerable to the risks of soil degradation. Moreover, the results from this study will aid decision makers in better conservation planning of soil and water resources.

    Progressive Efforts in the Implementation of Integrated Water Resources Management (IWRM) in Uganda.
    (Kabale University, 2024) Turyasingura, Benson; Akatwijuka, Rogers; Tumwesigye, Wycliffe; Ayiga, Natal; Ruhiiga, Tabukeli Musigi; Banerjee, Abhishek; Benzougagh, Brahim; Frolov, Denis
    Worldwide, water is essential in creating the environment and human life. Uganda’s Vision 2040 promises general use and safe access to drinking water for all Ugandans. Today, 14% of the population in Uganda have access to potable managed water, and 78% of rural communities have access to the sanitation system, and by 2040, the number is expected to have doubled.“ If the population is to exercise its constitutional right to receive a dependable, safe, and inexpensive water supply, it is imperative that infrastructure for water supply be provided. We assessed the progressive efforts in the implementation of integrated water resources management in Uganda, challenges, opportunities, and policies for water management.” Explorations for the keywords “water” AND “water resources”, AND “water management” were used in this study. A total of 125 papers were selected for this study from 2013 to 2022, from Scopus, Google Scholar, Science Direct, and Web of Science, that were found relevant for this study and were selected and discussed. According to findings, the United States, the United Kingdom, China, and India were the leading publications. In the analysis of sources of journals by publications, the Science of The Total Environment was the leading. According to the analysis by the organizations, the leading was Wageningen University and Research, followed by the University of Chinese Academy of Sciences. It was concluded that the problems of effectiveness in water resource management are still a global change and little effort has been made. To bridge the gap from science to policymaking in the water resources nexus, it is vital to enhance stakeholder collaboration, water resource tradeoffs, and regional development and preservation by optimizing the ecological water resource pattern.

    The complementary Role of Indigenous Knowledge Systems in Landslide Disaster Management in Kanungu District, Uganda
    (Kabale University, 2024) Turyasingura, Benson; Ayiga, Natal; Benzougagh, Brahim; Kader, Shuraik; Kumar, Singh Sudhir; Nuwe, John BOSCO; Gweyi-Onyango, Joseph P.; Bojago, Elias
    This study aimed to investigate the use and effectiveness of Indigenous Knowledge Systems (IKS) in managing landslides in Kanungu District, Uganda. The study used the Likert scale and the multivariate probit (MVP) model and found that marginalization was a significant challenge facing local interventions in landslide disaster management. Factors such as farm size, credit availability, social group membership, access to extension services, farming experience, accessibility of weather and climatic information, and perception of climatic changes influenced the adoption of IKS, both positively and negatively. The study concludes that education programs should focus on farmer capacity building to mitigate landslide risks and emphasize the application of IKS in landslide hazard management.
