Examining how long fallow swidden systems impact upon livelihood and ecosystem services outcomes compared with alternative land-uses in the uplands of Southeast Asia

Swidden agriculture or shifting cultivation has been practised in the uplands of Southeast Asia for centuries and is estimated to support up to 500 million people - most of whom are poor, natural resource reliant uplanders. Recently, however, dramatic land-use transformations have generated social, economic and ecological impacts that have affected the extent, practice and outcomes of swidden in the region. While certain socio-ecological trends are clear, how these broader land-use changes impact upon local livelihoods and ecosystem services remains uncertain. This systematic review protocol therefore proposes a methodological approach to analysing the evidence on the range of possible outcomes such land-use changes have on swidden and associated livelihood and ecosystem services over time and space.
