Abstract: The earth's ever increasing human population have bestowed varied ecological signatures replicated in spatial mutations in drainage basins and watersheds. This is evident in the Mbum Plateau as anthropogenic actions have been impacting water supply basins through land cover changes with grievous impacts on water availability and supply for utilization by the population. The aim of this study is to examine the impact of drainage basin anthropisation on water availability in the Mbum plateau. A correlational research design with mixed qualitative and quantitative research approaches is used to detect the annual rates of drainage basins changes from 1980 to 2021 and analysed at spatiotemporal scales, computed using ArcGIS 10.2. Data was collected from 230 household heads using a semi-structured questionnaire in 13 sampled villages and secondary sources from published and unpublished documents. Descriptive and inferential statistics are used for the analysis. Using the Pearson Correlation to determine the link between drainage basin anthropisation and water availability, results reveal a calculated value of -0.060, signifying a negative relationship between drainage basin anthropisation and water availability. This indicates that there has been a significant decline in water supply availability as anthropogenic activities surges in the highland area. Positive water supply implications are apparent in areas that are forested with severe decline in anthropised and degraded watersheds. The study recommends plausible watershed management options in the phase of increasing anthropogenic activities with the high use of integrated, participatory and conservation approaches in the Mbum highlands.

Abstract: Prosopis juliflora is one of the most popular damaging foreign species that are invasive harming the environment and the economy in arid and semi-arid environments. It is threatening pastoral and agro-pastoral livelihoods in particular as it spreads quickly through rangelands, croplands, and forests. Parts of national parks and wildlife refuges have been invaded by Prosopis, endangering biodiversity. Its quick spread throughout the environment is encouraged by several factors. Among the key factors are its adaptability to a wide range of climatic conditions, efficient mechanism for dispersal, allelopathic effect, prolific nature, presence of a significant in the soil ecosystem, there is a seed bank., and quick and strong coppicing abilities. Prosopis can have negative crop yield, animal and human health consequences, and the composition and diversity of plant species. The tree has potential uses for fuel, charcoal, fodder, food, bio-char, bio-control, windbreaks, shade, building and furniture materials, and soil stabilization, despite its drawbacks. Through carbon sequestration, it can also be used to treat various diseases and improve environmental conditions. On the other hand, effective control methods and management of this weed have been identified as manual, mechanical, chemical, biological, and utilization control methods. To get them under control, it is urgent to create management plans that are both economically and environmentally sound. Therefore, this review's goal was to investigate Prosopis' distribution, effects, advantages, and potential management strategies.
