Mng’ong’o, Marco; Munishi, Linus; Ndakidemi, Patrick; Blake, William; Comber, Sean; Hutchinson, Thomas (Heliyon, 2021-07-07)The build-up of heavy metals (HM) in agricultural soils accelerates the HM uptake by plants, which could potentially affect food quality and food safety. Here we studied the status and bioaccumulation of HM from soils to ... -

Changes in sedimentation ... -
Drivers of increased soil erosion in East Africa’s agro-pastoral systems: changing interactions between the social, economic and natural domains
Wynants, Maarten; Kelly, Claire; Mtei, Kelvin; Munishi, Linus; Patrick, Aloyce; Rabinovich, Anna; Nasseri, Mona; Gilvear, David; Roberts, Neil; Boeckx, Pascal; Wilson, Geoff; Blake, William; Ndakidemi, Patrick (Springer, 2019-06-08)Increased soil erosion is one of the main drivers of land degradation in East Africa’s agricultural and pastoral landscapes. This wicked problem is rooted in historic disruptions to co-adapted agro-pastoral systems. ... -
