    A Review of the Effects of Climate Change on Water Resources in Sub-Saharan Africa
    (African Journal of Climate Change and Resource Sustainability, 2023-06-23) Turyasingura, Benson; Ngabirano, Hannington; Kinyi, Hellen Wambui; Singh, Sudhir Kumar
    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

    A Review of the Effects of Climate Change on Water Resources in Sub-Saharan Africa
    (African Journal of Climate Change and Resource Sustainability, 2023-06-23) Turyasingura, Benson; Ngabirano, Hannington; Kinyi, Hellen Wambui; Ayiga, Natal; Sudhir, Kumar Singh
    With respect to the fact that the environment of today is not the exact environment of tomorrow, there is a need to develop a sustainable mechanism that either pauses the adverse effect of human activities on natural resources and the climate or create mitigating factors that reverse the negative climate evolution. For this to happen, researchers and stakeholders require adequate academic information that can be used for policies formulation and strategic planning. It is for this reason that the East African Nature and Science Organization hosts this open access academic journal on climate change and resource sustainability.

    Anti-obesity Effects of Erythrina Abyssinica Stem Bark Extract in Flies Exposed to a High Fat Diet
    (Heliyon, 2022) Asiimwe, Oscar Hilary; Wampande, Eddie; Rubaihayo, John; Kasozi, Keneth Iceland; Kinyi, Hellen Wambui
    An in vitro assay on Sigmoidin A from Erythrina abyssinica stem bark revealed its potency to inhibit pancreatic lipase. However, studies indicate activity of extract bioactive compounds in combination far exceed the favorable effects of each individual compound due to synergy and additive effects. In this study, we provide information on the effect of E. abyssinica stem bark extract in Drosophila melanogaster. The objective of the study was to determine the safety and effects of E. abyssinica stem bark extract on fly survival, body weight, triglycerides, sterol, total protein, and catalase activity of obese male D. melanogaster.
