Résumé : The economic assessment of climate change adaptation basically consists in balancing costs and benefits of actions considered when addressing climate change (CC) threats. The purpose of economic evaluation in the assessment process of CC adaptation actions is essentially to provide figures for the comparison of different possibilities. In the context of the 3 EcoAdapt south American sites (Los Perico-Manantiales watershed in Argentina - BMJ, Zapoco watershed in Bolivia - BMCh and Alto Malleco in Chile - BMAAM), economic evaluation is to rely on a shared understanding of local contexts and the economic drivers of current dynamics. We focus on specific actions considered in these contexts so as to address unsustainable dynamics. The present report D3.4 provides a framework for economic evaluation: its context and the approach under development; the elements of costs and benefits that enter the analysis; and how uncertainty and irreversibility can be accounted for when using economic evaluation results. The initial panorama of the context of the economic evaluation recalls synthetically what we know about the territories and their people in terms of scales, activities and living conditions and about the extent to which they are affected by climate. Such introduction aims at facilitating the understanding of the types of actions considered for climate change adaptation. Then the economist standpoint on climate adaptation is explained and the perimeter of the evaluation is defined: 15 actions in BMJ, 11 in BMCh and 9 in BMAAM. Twelve fields of investigation are identified, for which available information is synthetized and on-going research on the elements of costs and benefits is described, so as to both make a progress status, and actualize the road map for integrating economic evaluation in modelling (task 3.2), scenario development (task 4.2) and implementation (task 5.3). A final section illustrates the possible use of the economic analysis to reveal or highlight specific characteristics of the actions considered, for instance: their time horizons and links with inexplicit future benefits or costs; their progressive definition that requires to start the evaluation; their reliance on resources considered free.
