The region of Southern Ethiopia (Borana) and Northern Kenya (Marsabit) is characterised by erratic rainfall, limited surface water, aridity, frequent droughts. An important adaptive response to these conditions, uncertain antiquity, has been the hand-excavation a sequence deep wells at key locations often along seasonal riverbeds valley bottoms where subterranean aquifers can be tapped. Sophisticated indigenous water management systems have developed ensure equitable access critical...
Extensive land transformation leads to habitat loss, which directly affects and fragments species habitats. Such transformations can adversely affect fodder availability for bees thus colony strength with consequences rural communities that use bee keeping as a livelihood option. Quantification of the landscape structure is critical if linkages between honey health are be well understood. In this study, random forest algorithm was used on dual-polarized multi-season Sentinel-1A (S1)...
Landscape fragmentation and habitat loss at multiple scales directly affect species abundance, diversity, productivity. There is a paucity of information about the effect landscape structure diversity on honey bee colony strength in Africa. Here, we present new insights into relationship between metrics such as patch size, shape, connectivity, composition, configuration (Apis mellifera) characteristics. Remote-sensing-based variables were linked to typical highly fragmented smallholder...
This research reports a mapping of aflatoxin risk in the milk value chain Kenya using geographic information systems (GIS) approach.The objective was to spatially locate regions at by taking into account biophysical and socio-economic factors such as humidity rainfall, dairy cattle density, maize production travel time urban centres.This combined with historical data outbreaks obtained from literature search geo-referenced.Median values for datasets were then used define...
In Africa there is a scarcity of information on how plant species that can provide forage for honey bees vary across differentially structured landscapes, and what are the implications such variabilities colony integrity. This research presents new insights into diversity richness pollen collected by Apis mellifera scutellata, subspecies Western bee native to sub-Saharan Africa, at six study sites different degradation levels within semi-arid landscape in Kenya. Ten colonies were established...
