AU Pribadi, U.A. AU Anandadas, A. AB Climate change is an increasingly urgent global environmental and humanitarian problem, threatening disruption of ecological processes, alterations of land-based and aquatic food production systems, increasing risks to human health, challenges to maintaining and improving human wellbeing, risks to biodiversity and species survival, undermining of economic growth and resilience, and increasing conflict and violence (IPCC 2014a). Tropical deforestation and forest degradation are one key part of the problem, with 12% of total GHG emissions in the period 2000-2009 coming from forests and other land uses (IPCC 2014b, 16) and therefore potentially an important part of the solution (Goodman and Herold 2014).
