Restoring grassland by managing invasive tree species in Tanzania
03.07.2020
Invasive weeds, shrubs and trees keep invading arable land in many African countries. They cause land erosion due to the loss of the grasslands that are habitats for native plants and animals. Researchers investigate in a bottom-up decision making process together with local stakeholders how to restore grassland by managing invasive species.
The Prosopis or mesquite tree (Prosopis juliflora) originates from South America and was introduced in parts of Africa for fighting desertification. However, the mesquite tree has severe economic and environmental impacts in Tanzania. It takes over pastoral grasslands and its deep roots use groundwater. Goats and sheep get injured by its thorns.
The r4dWoody Weedsproject supports local communities in developing and implementing sustainable land management strategies against invasive species. The decision making process involves local communities and other stakeholders and also ensures women’s participation. Manual and chemical methods were tested for removing mesquite trees and re-establishing grassland.
This video-clip was produced as part of the r4d programme Digital Storytellers synthesis project. Its contents were filmed and selected by René Eschen from CABI Switzerland in collaboration with local partners in Tanzania. The digital storytelling process was accompanied and supported by Paitití Lab.Watch on YouTube.
