The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status ...
Gender in Agroforestry: Implications for Action-Research
Women in sub-Saharan Africa are major contributors
to the agricultural economy, but their lower access
than men to productive resources and opportunities,
limits them from achieving optimal production. This
paper gives a ...
Simulation analysis of factors affecting sorghum yield at selected sites in eastern and southern Africa, with emphasis on increasing temperatures
Global warming is widely predicted to decrease crop yields in tropical, sub-tropical and Mediterranean
climatic regions as a result of a speeding up of phenological development and shortening of the time
to maturity. We ...
Past and present dynamics of sorghum and pearl millet diversity in Mount Kenya region
Crop populations in smallholder farming systems are shaped by the interaction of biological,
ecological, and social processes, occurring on different spatiotemporal scales.
Understanding these dynamics is fundamental for ...
Exploring the challenges with soil data in regional land use analysis
Over recent decades, environmentalmodels have gradually replaced traditional, qualitative land evaluation in regional
land use analysis (RLUA). This changed the data requirements as the environmental models require ...
Determination of seasonal rainfall variability, onset and cessation in semi-arid Tharaka district, Kenya
The study quantified rainfall variability for March–
May (MAM) and October–December (OND) seasons in
Tharaka district, Kenya. The parameters analysed were interannual
variability of seasonal rainfall, onset and cessation
using ...
Edifice growth and collapse of the Pliocene Mt. Kenya: Evidence of large scale debris avalanches on a high altitude glaciated volcano
The cyclic growth and destruction of the Late Cenozoic Stratovolcano Mt. Kenya have been reconstructed for its
southeastern segment. At least three major debris avalanche deposits have been reconstructed and dated. The
oldest ...
Influence of putative forest refugia and biogeographic barriers on the level and distribution of genetic variation in an African savannah tree, Khaya senegalensis (Desr.) A. Juss
Phylogeographic studies of tropical and subtropical
tree species provide an ideal method to study the role of forest
refugia in the structuring of genetic diversity in contemporary
populations. To date, most studies have ...
Spatial variation in the willingness to accept payment for conservation of a migratory wildlife corridor in the Athi-‐Kaputiei Plains, Kenya.
Payments

Correlations, Path Coefficient Analysis and Heritability for Quantitative Traits in Finger Millet Landraces
Knowledge of association between traits and heritability is important in breeding for purposes of effective trait selection. Such information on finger millet in east Africa is very limited. This study was intended to ...
