A combined DPSIR and SAF approach for the adaptive management of beach erosion in Monte Hermoso and Pehuen Co (Argentina)

Coastal areas experience multiple pressures from anthropogenic activities that negatively change the ecological and environmental status of beaches and impact human welfare. The focus of this paper is coastal erosion, an issue that is very relevant for Argentina, the second largest nation in Latin America with an extensive coastline of nearly 5000 km. Coastal erosion decreases the attractiveness of coastal areas for tourism development, leading to considerable economic impacts. In this paper, two complementary approaches, the Driver-Pressure-State-Impact-Response (DPSIR) and the Systems Approach Framework (SAF), were used to analyse two beach resorts in Argentina: Monte Hermoso and Pehuen Co.Application of the SAF included stakeholder mapping, governance (institutional) mapping and issue identification. During the participatory meetings with stakeholders and decision makers, the problem of coastal erosion was identified as the most important in the region. The joint approach of DPSIR and SAF contributed to: (i) the determination and description of the economic drivers of coastal erosion; (ii) the identification of the associated activities and pressures; (iii) the assessment of the ecological and environmental state of coastal areas; (iv) the assessment of impacts of environmental changes on human wellbeing; and finally (v) a proposal of the possible management responses for mitigating the coastal erosion problem and the sustainable development of the region to the responsible authorities.
