Lightning has received a lot of attention in scientific literature during the recent decade, not only because it is an impressive atmospheric phenomenon but also its associations with severe storms that cause unprecedented damages to agriculture, electric power networks, property, and life. This study assessed the Spatio-temporal characteristics of...
Drought occurrences in Rakai district take a strange model and it has been rampantly increasing causing reduced income levels for farmers, reduced farm yields, increased food insecurity and migration, wetland degradation, illness and loss of livestock. The purpose of this study was to investigate past and future characteristics of drought due to cl...
Monitoring and assessment of drought is key to modelling, impact assessment, mitigation and prediction of occurrence. The Upper Tana River watershed hosts two of Kenya's main water towers, Mt. Kenya and Aberdare Ranges, and is increasingly under threat from reduced water levels in the river basins due to unsustainable anthropogenic activities. The...
Aims: To identify the most appropriate drought indices for the identification and monitoring of historical meteorological and agricultural drought incidences and to explore the spatial characteristics of these droughts. Study design: GIS-based empirical research design. Place and Duration of Study: Upper Tana River Watershed, Kenya drought analysis...
