The Mahale ecosystem bordering Lake Tanganyika is globally important for its tropical forest biodiversity, as well as for supporting the local livelihoods. In recent years, there has been major disturbance to these communities and large refugee in-migration from regional conflicts. This upheaval has increased poverty and severely impacted on the ecosystem’s natural resource base. LTS was contracted to lead the design and development of the monitoring and evaluation plan for the Mahale Ecosystem Management Project which was co-financed by the European Commission and implemented by Frankfurt Zoological Society in partnership with Tanzania National Parks. LTS trained project staff in logical framework based monitoring and evaluation, and facilitated the development of a monitoring and evaluation plan for the project. The task was also expanded to assist the project team to develop a similar monitoring and evaluation plan for the Mahale Mountains National Park Management Plan.
