An analytical assessment of climate change trends and their impacts on hydropower in Sondu Miriu River Basin, Kenya
Hydropower is cost effective environment friendly and worldwide proven sustainable energy source. Driven by streamflow stream flows, it is vulnerable to climate change and land use change. The hydropower production from the two-existing run-of-river hydropower projects on the Sondu Miriu River are vulnerable to rainfall variability and requires proper understanding of the climate change trends and policies to support...

Phenology and mechanisms of the early upwelling formation in the southern coast of Senegal
Mechanisms of the interannual variability of upwelling onset dates on the Petite-Cote of Senegal are investigated using daily NEMO model data outputs and NOAA ocean surface temperature observations (OISST). We first determined the phenology (onset dates, end dates, duration and occupied area of the upwelling) over the Petite-Côte located in south of the Senegalese coast. Our results show that upwelling in the...

Characterizing groundwater vulnerability in developing urban settings using DRASTIC-LuPa approach: A case study of Aba City, Nigeria
The impact of certain unregulated land-use activities harms the quality of water resources and reduces the sufficiency of drinking water in many developing countries. This study aimed to capture the impact of such activities and evaluate the specific groundwater vulnerability using a modified DRASTIC approach. The DRASTIC-LuPa was proposed and implemented for Aba City, Nigeria by incorporating land-use and the...

Uroclhoa mosambincensis: A potential native phytoremediator for soils contaminated with arsenic
Industrial development has caused the contamination of the environment, leading to biodiversity loss and human health concerns. The use of native plants and/or their associated microbiota is a sustainable solution for reducing or transforming contaminants into less harmful forms. This study was conducted to evaluate the remedial potential of Uroclhoa mosambincensis in soils contaminated with arsenic. In a greenhouse...

The environmental impact of landfill fires and their contaminant plumes at the Chunga landfill site, Lusaka, Zambia
The management of solid waste is recognised as a challenging activity with respect to the environment, particularly within rapidly growing urban centres in Lower Income Countries. This paper examines the issue of landfill-waste-generated fires and resultant pollution plumes sourced within the Chunga Landfill Site, Lusaka, Zambia. The authors present the results of a geospatial analysis research programme to map and...
