    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 in order 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 were selected for this study from 1945–2022, from Scopus, Google Scholar, Science Direct, and Web of Science, that 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

    Re-thinking on land degradation and its impacts on livelihoods of the farmers in Kanungu District, Uganda
    (2022) Turyasingura, Benson; Ayiga, Natal; Benzougagh, Brahim
    Worldwide, land degradation reduces the productivity of agricultural land by roughly 75%. Land degradation has made it difficult for people to make a living in Uganda, one of the world's poorest nations. Land degradation in Uganda poses a severe danger to rural populations' ability to support themselves and little effort has been done. The primary natural resource used by humans for economic, social, infrastructure, and other human endeavors is land. Land resources are so crucial in determining rural livelihoods, and the absence of sustainable land management techniques results in land degradation. Results: The study findings proved that there was a significant positive relationship between the effects of land degradation and the livelihoods of farmers (p 0.01, r =.530**) in Kanungu District, which suggests that adoption of new seed varieties which can withstand harsh climatic conditions, strengthening agricultural reforms, and agroforestry would improve the livelihoods of local farmers to improve their savings and production of quality crop products. Therefore, the alternative hypothesis was therefore accepted and it was concluded that "There is a significant relationship between land degradation and the livelihoods of farmers in Kanungu District

    A Systematic Review and Meta-analysis of Climate Change and Water Resources in Sub-Sahara Africa
    (2022) Turyasingura, Benson; Chavula, Petros; Hirwa, Hubert; Mohammed, Fatima S.; Ayiga, Natal; Bojago, Elias; Benzougagh, Brahim; Ngabirano, Hannington
    Variations in precipitation that affect water resources have drawn a lot of attention to climate change-related water quality issues in recent years. Point and non-point source contaminants have an impact on water quality due to seasonal rainfall variability, and rainfall events are crucial in spreading these pollutants. Sub-Saharan Africa has the least stable access to freshwater supplies. Numerous academics have undertaken extensive research on the connection between climate change and water resources, yielding significant research findings. However, there is a dearth of quantitative analysis and thorough evaluation of research accomplishments. The purpose of the study was to undertake an organized literature review on the topic of examining the relationship between Sub-Saharan Africa's water resources and climate change. In the first segment, Vos-Viewer was used to map, study the literature, and identify any gaps in order to evaluate the impact of rainfall variability on water quality. The adaptation and mitigation strategies for water availability were described in the second section. This report utilizes the VOS-Viewer bibliometric software to create a combative network and keyword co-occurrence map based on the pertinent literature on the topics of climate change and water resources in the core collection of the Web of Science database and dimension. According to the study's findings,
