Excessive levels of nutrients, particularly nitrogen and phosphorus, can trigger eutrophication leading to harmful algal blooms oxygen depletion thus endangering freshwater fish species. Despite the widespread awareness these risks, efforts protect species remain largely ineffective, especially under climate change other anthropogenic pressures. This study therefore identifies potential future hotspots for nutrient pollution in African river systems, specifically assessing risk that elevated...
Abstract Understanding the spatial and temporal patterns of sediment loading in water bodies is crucial for effective quality management. Remote sensing (RS) has emerged as a valuable reliable tool monitoring turbidity, which can provide insights into dynamics bodies. In this study, we investigate potential turbidity data derived from RS to explain simulated Lake Tana basin, Ethiopia. Utilizing existing lake Copernicus Global Land Service (CGLS) seasonal multiyear trends river loadings Soil...
Climate change poses significant challenges to water quality in river catchments globally, particularly regions heavily dependent on natural systems for agriculture, domestic use, and biodiversity conservation. The Yala River Catchment Western Kenya, a critical resource the region, is increasingly threatened by climate variability its associated impacts. Rising temperatures changing rainfall patterns exacerbate sediment transport, nutrient runoff, overall degradation. This study evaluates...
EGU NH1.7A coupled mechanistic and in situ data approach to quantify the water retention potential of Nature-Based Solutions The increasing frequency intensity droughts poses great challenges availability functioning natural ecosystems. In response this, nature-based solutions (NbS) have emerged as a promising alternative traditional infrastructure. NbS offer multiple benefits, including retention, improved quality, biodiversity conservation, carbon sequestration. However, despite...
Climate change is projected to increase the volatility of agricultural productivity within Sub-Saharan Africa region. However, current knowledge climate impacts in this region largely derived from coarse-grid global datasets that lack sufficient detail for local applications. The are thus generalized across large spatial scales, with a limited representation differential exposure It necessary conduct localized assessments derive vulnerabilities and develop context-specific mitigation...
This study explores the applicability of 13 globally-derived Chlorophyll-a (CHL) products from optical satellite remote sensing to support local water quality management in Lake Nicaragua. The temporal and spatial consistency between was analyzed, as well their agreement with in-situ data collected 2011 2016. Climate Change Initiative (CCI) CHL product identified most stable reliable, suggesting its suitability for monitoring However, correlation this measurements weak, attributed sparse...
Soil moisture plays a crucial role in the earth's system cycle by connecting water, energy, and carbon cycles. It actively influences hydrological processes affects occurrence of climate-related hazards, such as droughts, heatwaves, wildfires. This places soil at centre agro- biometeorological monitoring forecasting. Despite its role, global network observations remains least developed among major land-based components cycle, with strong regional imbalances coverage. Remote sensing products...
Climate change is projected to negatively affect agricultural productivity globally, with disproportionate effects in the Sub-Saharan region where vulnerability compounded by a high reliance on rainfed systems and low that limits options for adaptations. Current knowledge of climate impacts largely derived from global regional scale studies are generalized over regions, yet heterogeneous magnitudes could vary. This highlights need conduct localized assessments derive local vulnerabilities...
