Mountain farmers and ecosystems: changing land use and livelihoods in Mount Rungwe, Tanzania

ABSTRACT

This paper analyses long-term and incremental land use changes that have taken place in Mount Rungwe ecosystem in Tanzania from 1973 to 2010 basing on information derived from satellite images, household socio-economic data, focus group discussions and interviews with key informants. While most literature on land use change reports negative effects, land use changes in Mount Rungwe ecosystem have positively benefited communities through more diversification and greater commercialisation. The paper demonstrates that rural communities’ livelihoods are both a cause and a result of changes in the natural Mount Rungwe ecosystem. The changes in land use through cropping patterns and reforestation took advantage of opportunities from population increase, access to markets and agricultural resources management. Consequently, the changes have qualitatively improved communities’ livelihoods and forest ecosystems. The paper broadens our understanding on the potential land use changes in mountain ecosystems for enhancing rural livelihoods and the environment in line with the Boserup’s agricultural intensification theory.
