ABSTRACT: Most countries have suffered forest loss or degradation over the last two decades. Opportunities for restoration exist on all continents and are huge in terms of area, although the estimate of their extent is rough. The Global Partnership on Forest Landscape Restoration therefore asked a consortium of organizations led by the World Resources Institute to map the global opportunities for restoration using only worldwide scale available data. To this purpose an identification of priority restoration sites is fundamental at a much more local scale using local data sets. Therefore, this study introduces a Geographic Information System-based (GIS) methodology to identify forest landscape restoration (FLR) priorities in Madagascar and evaluate them with respect to a set of ecological and socioeconomic available and spatialized criteria using multi criteria decision analysis (MCDA). Those criteria were defined through consultations and workshops where many experts in the field were asked on how some criteria might contribute to the forest landscape restoration in the country. Once the criteria listed and the prioritization were well defined, two different multicriteria assessment approachs were adopted and compared for the FLR opportunity assessment: Weighted Liner Composition (WLC) and Analytic Hierarchy Process (AHP). 26 criteria were provided in total and grouped into three main objectives relating to water resource management, biodiversity conservation and soil protection. This research shows that the resulted map obtained from the two methods are significantly different as the weighting of the criteria are based on different process and have different scenario based models of landscape change. These simulations can be used as a guide for forest and ecological planners and designers in order to better cope with the environmental and socioeconomic challenges on forest landscape management.
