Titre : Clearing of woody weeds to restore grassland in Kenya may yield major livelihood benefits

A new study suggests that clearing the invasive woody weed Prosopis julifora and grassland restoration in Baringo County, Kenya, may have significant financial benefits for local stakeholders and contribute to climate change mitigation

Présentation
Climate change, land degradation, and invasive alien species (IAS) such as Prosopis julifora are major threats to livelihoods in arid and semi-arid regions, having negative impacts on ecosystem services, including vegetation biomass, which is a prime resource for pastoralists and agro-pastoralists.

The scientists studied the impacts of Prosopis invasion and grassland degradation on soil organic carbon (SOC) in nine sublocations in Baringo County, where it was introduced in the 1980s, and promoted by the Kenyan government to provide wind breaks, a source of timber, fuelwood and charcoal.

The study combined data collected by several Ph.D. students of the Woody Weeds project, such as socio-economic data to determine the size of the budget available for Prosopis management (Bekele et al. 2018) and the financial benefits of making charcoal from removed trees, soil measurements to assess changes in SOC following Prosopis removal (Mbaabu et al. 2020) and establishment of grassland. The data were linked to spatially explicit land-cover and land-use maps derived from satellite data (Mbaabu et al. 2019). Then, spatially explicit invasive alien species (IAS) management and restoration scenarios were generated.
