Abstract

T he imperative of land-use change for climate change adaptation in the agriculture sector has a considerable potential to jeopardize the sustainability of ecosystems? functions, particularly for small-scale farmers in the most vulnerable agro- ecological systems where such functions are key to livelihoods sustainability. According to the IPCC, effective climate change adaptation strategies are expected to recognize land-use sustainability by focusing on landscape development. So far, climate change adaptation has received considerable attention among the economics scholarship. The treatment of this topic has covered various approaches. Therefore, it is appealing to investigate the treatment of land-use change in climate change adaptation economics. To that end, this paper (i) overviews systematically the essential ideas behind the commonly applied microeconomic frameworks in the literature, and (ii) attempts to identify the position of each approach to the economic research for climate change adaptation, by proposing a unifying theoretical structure on which the contribution of each approach in the climate change adaptation economics research can be mapped out. The sustainable livelihood framework is selected on the basis of its explicit consideration of both aspects of interest (climate change adaptation and sustainability of land resource use). The risk chain and the Driver-Pressure-State-Impact-Response (DPSIR) model are used as underlying processes. The review unveils the central instrumental role played by the costing approach (cost-benefit/cost effectiveness analyses), although this strand stands out to be underexplored in agricultural adaptation literature. It concludes by proposing possible avenues for future microeconomic researches. Keywords: Climate Change Adaptation; Land-use Change; Sustainable Livelihood Framework; DPSIR; Risk Chain
