    Upland agriculture and forest uses in Southeast Asia account for perhaps 2 million square kilometres and support between 100 and 500 million people (Cramb 2007; Mertz et al. 2009). Swidden agriculture (or shifting cultivation) has for centuries formed the basis of land uses, livelihoods and customs in the uplands. As traditionally practised, swidden involves the intermittent clearing of small patches of forest for subsistence food crop production, followed by longer periods of fallow in which forest regrowth restores productivity to the land. Long-fallow swiddens can yield complex assemblages of forest and other vegetation in unique mosaics comprised of opencanopy tree...

    Long-fallow swidden systems in the uplands of Southeast Asia have undergone profound changes in extent, practice and configuration since the Second World War with subsequent influences on livelihood outcomes and ecosystem services (van Vliet et al. 2012). As such, the review’s main objective is to examine the evidence relating to the positive or negative impacts of changes in long-fallow swidden on livelihood and ecosystem services outcomes compared to alternative land uses. During the stakeholder workshop, it was decided to examine this objective in line with the following main question:

    How do long fallow swidden systems impact upon livelihood security and...

    Authors agreed after the workshop (in March 2014) that the original question and overall scope of the systematic review needed further refining. A scoping exercise was therefore conducted to determine the size of the body of literature (and the scale of the task and resources required) and also to understand how select literature discusses livelihood security and ecosystem services in long-fallow swidden systems.

    Two reviewers tested 86 different search terms and string combinations across four different databases (Web of Science, Science Direct, CAB Abstracts and Scopus) and one search engine (Google Scholar). The original search terms identified at the workshop...

    This systematic review protocol therefore proposes a methodological approach to analyse 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....
