Coastal erosion has caused beach loss and threatens first-row beachfront houses and other nearshore structures in Progreso, Yucatán (Mexico). This multidisciplinary project combines shoreline analysis, social research and stakeholder mapping to develop an integrated understanding of coastal erosion, its effects and the socio-environmental context in the study area. The aim is to translate this knowledge into a coordinated and sustainable approach that promotes coastal resilience.

The shoreline analysis that was performed using satellite imagery showed evidence of both accretion and erosion in the study area. A forecast of the coastline retreat showed that in the western part of the Progreso area, the number of properties that lie within 10 meters of the shoreline is expected to double within the next decade.
The findings of the social analysis and stakeholder mapping revealed a communication and knowledge gap. The communication gap occurs between neighbours, so among coastal homeowners, but also between them and the governmental institutions. There is a knowledge gap due to the need for knowledge sharing among coastal homeowners.

A solution for the coastal erosion problem in the Progreso area is only possible by first implementing a social strategy; otherwise, no physical measure will be effective. Thus, the coastal community committee (CCC) is proposed to address the identified communication and knowledge gaps, as well as the fragmented responsibilities. The CCC is a group that makes decisions about measures to improve coastal resilience and engages local residents and stakeholders. In order to physically reconstruct a resilient coast, the use of a Sandsaver is proposed for sand accretion. To achieve long-term coastal resilience, dune formation is necessary. The report includes a plan for testing this Sandsaver and also a plan for implementing the CCC.
