Development Corridors Partnership

Development is occurring rapidly across Africa which makes it difficult to ensure that current and future planning and management does not compromise conservation objectives. To guarantee that development is sustainable in the long-term, we must anticipate changes in land use, ecosystem service provisioning, and livelihoods. This is a daunting task, particularly as we live in an uncertain world where social and environmental changes are unpredictable. In addition, stakeholders’ priorities are often conflicting, which means trade-offs need to be made in land management decisions (e.g. food vs. energy needs). One way to approach these challenges is to use participatory scenario planning to model different socio-economic, climatic and environmental futures, and changes in land use, at local, regional and national scales.

Participatory scenario planning allows us to assess the cumulative social and environmental impacts of development. It uses current and alternative development pathways to see how they will each affect diverse, plausible futures, which allows decision-makers to make better-informed decisions. Working with and providing learning opportunities for stakeholders is a key part of this process.

In the Development Corridors Partnership, we use participatory scenario planning to systematically investigate the potential impacts of development corridors in Kenya and Tanzania, to ensure infrastructure investment is sustainable and resilient.

Dr Jessica Thorn (University of York), with the University of Nairobi Institute of Climate Change and Adaptation, African Conservation Centre, and Sokoine University of Agriculture College of Forestry and Natural Resources, facilitate our scenarios workshops. These workshops bring together researchers, community and non-governmental organisations, businesses, donors, and government officials, working across scales and sectors. Jessica and the team are investigating the impacts of the Standard Gauge Railway and the Southern Agricultural Growth Corridor of Tanzania as case studies of controversial, current and important development corridors. As of August 2019, workshops have been held across Kenya in Mombasa, Voi, Nairobi, Suswa, Naivasha, and Kisumu; and in Tanzania, in Ifakara in the Kilombero Valley. Our findings are triangulated using in-depth key informant interviews, household surveys, and field visits – examining multiple data sources to validate results, and gain a more detailed understanding of findings.
