0 Restoring rangelands for nutrition and health for humans and livestock - New Research Project

 Drylands Transform is the new interdisciplinary research project starting up in the border region between Uganda and Kenya. The research team –coordinated by SLU – wants to modify the ongoing negative spiral of land, livestock and livelihood degradation into a positive transformation. The project aims to contribute to several of the United Nations global sustainable development goals.Drylands cover 40% of the global land area and hosts 2 billion people of which 90% live in low- or middle-income countries. Drylands often face severe land degradation, low agricultural productivity, rapid population growth, widespread poverty and poor health....

0 Tracking Sources and Fate of Groundwater Nitrate in Kisumu City and Kano Plains, Kenya

Spatial distribution of the groundwater sampling points Groundwater nitrate (NO3−) pollution sources and in situ attenuation were investigated in Kisumu city and Kano plains. Samples from 62 groundwater wells consisting of shallow wells (hand dug, depth <10 m) and boreholes (machine drilled, depth >15 m) were obtained during wet (May–July 2017) and dry (February 2018) seasons and analyzed for physicochemical and isotopic (δ15N-NO3−, δ18O-NO3−, and δ11B) parameters. Groundwater NO3− concentrations ranged from <0.04 to 90.6 mg L−1. Boreholes in Ahero town showed significantly higher NO3− (20.0–70.0 mg L−1) than boreholes...
