Coastal Adaptation Plan for the Lima Metropolitan Area


Place: Lima

Country: Perú

Date: 2022 - 2023

Design: IHCantabria - LANDLAB - INCOSA

Promoter: Ministerio del Ambiente de Perú, Global Environment Facility, World Wildlife Fund, financiado por el Banco Interamericano de Desarrollo

LandLab team: Miriam García, David Camacho, Pere Marieges, Maria Sans


Nowadays, coastal areas are specially vulnerable areas to climate change effects, as they are part of the limit between land and sea, a highly dynamic zone. Within this context, the consortium between Instituto de Hidráulica Ambiental de Cantabria, LandLab and Incosa is created in order to ellaborate an adaptation plan to minimize these effects.

The metropolitan coast of Lima extends along approximately 100 km facing the Pacific Ocean. It is a changing coast, from alluvial plains and deltaic zones, to sedimentary or rocky coast. This great diversity of landscapes means a complex apporach to the site, characterized both by desert areas and by the emblematic Costa Verde, highly anthropized.

In order to decide adaptation mesaures, the coast is characterized in adaptation areas, considering which are the climate change effects on them and its affectation on human settlements. Thus, 16 adaptation areas are determined. For every area one or several adaptation strategies: seawards, backwards, consolidation, protection, non-structural or regulatory, to be discussed in local workshops with citizens, authorities and public technicians.


All the mesaures and strategies are contained in the Prospect, a document that shows the complete range of possible solutions and its great variety and differences between them.



This Plan means a step forward for LandLab, as it consolidates the methodology developed by Miriam García in her doctoral thesis and used for other projects. Specifically for this occasion, thanks to the common work between the LandLab team and IHCantabria researchers, a new charaterization and evaluation system has been developed, generating a mesaures and strategies catalogue.




All the mesaures proposed in an abstract way with the pills system are implemented through diagrams on the site. They are supposed to be part of the participation process, so they try to be very pedagogical in order to encourage the discussion between all thelocal agents.
