Abstract
In Yucatan , one of the main causes of coastal erosion is the use of "remedy" measures (groins or "espolones") by communities whom refuses to eliminate them (Medellin, 2015, Ruiz,2016). The erosion management approach has been dominated by engineering schemes resulting in beach values degradation and despite the development of recovery programs, no actions for protection/restoration of coastal ecosystems particularly , dunes have never been undertaken. In addition , dune flattening and vegetation elimination are common practices associated to coastal land use. Today , 56.1% of coast lacks of any type of dune/vegetation and 32% of sandy beaches are <10 m, increasing vulnerability to erosion and other natural hazards (Cuevas, 2016) . In this sense, the use of solutions designed to harness and mimic natural processes are emerging as an innovative approach for ecosystem restoration and erosion management. This work assessed a nature based structure (NBSt) capacity for dune building due to wind-blown sand accumulation and vegetation expansion for potential applications on erosion management.References
