Abstract
La investigación aborda cómo compatibilizar la vida en caletas pesqueras con los riesgos de desastres naturales costeros, como tsunamis y marejadas. Estos asentamientos dedicados a la pesca artesanal enfrentan una alta vulnerabilidad debido a su ubicación geográfica y dependencia del mar. A pesar de los riesgos, las caletas son espacios de gran valor cultural, social y económico para los pescadores, quienes tienen una estrecha relación con el mar, lo que define su identidad y forma de vida. El estudio se enfoca en la caleta de El Morro, en Talcahuano, Chile, ciudad históricamente afectada por desastres naturales, como el terremoto y tsunami de 2010.
El trabajo propone la integración de elementos naturales, como humedales y dunas a sistemas de infraestructuras verde buscando mitigar los efectos de los desastres naturales. Estos elementos ofrecen servicios ecosistémicos de regulación actuando como barreras naturales que protegen a las caletas. La investigación utiliza entrevistas y cartografías colaborativas con pescadores y habitantes, con el fin de entender que espacios de importancia identitaria, económica y cultural reconocen en la caleta.
Durante el desarrollo de la investigación se llega el hallazgo clave de la posibilidad de integración de los bosques de macroalgas en sistemas de infraestructura verde, lo que no solo ayuda a mitigar los riesgos de catástrofes costeras, sino que también refuerza la identidad local y ofrece beneficios económicos a través de la acuicultura. Mediante este hallazgo se propone que los sistemas de infraestructura verde pueden ser usados más que para mitigar sino también como espacios para potenciar la identidad y economía local.
La investigación ratifica la hipótesis de que los elementos naturales del paisaje pueden ser utilizados para desarrollar soluciones de mitigación conservando la identidad local. Se propone aplicar estas estrategias a otros proyectos urbanos, como los asociados al desarrollo sostenible de las caletas pesqueras, equilibrando las tensiones entre la extracción pesquera, ambiente y turismo.
The research addresses how to make life in fishing coves compatible with the risks of coastal natural disasters, such as tsunamis and storm surges. These settlements dedicated to artisanal fishing face high vulnerability due to their geographic location and dependence on the sea. Despite the risks, the coves are spaces of great cultural, social, and economic value for fishermen, who have a close relationship with the sea, which defines their identity and way of life. The study focuses on the El Morro cove, in Talcahuano, Chile, a city historically affected by natural disasters, such as the earthquake and tsunami of 2010. The work proposes the integration of natural elements, such as wetlands and dunes, into green infrastructure systems looking to mitigate the effects of natural disasters. These elements offer regulating ecosystem services by acting as natural barriers that protect the coves. The research uses interviews and collaborative mapping with fishermen and residents, in order to understand what spaces of identity, economic and cultural importance they recognize in the cove. During the development of the research, the key finding is the possibility of integrating macroalgae forests into green infrastructure systems, which not only helps mitigate the risks of coastal catastrophes but also reinforces local identity and offers economic benefits through aquaculture. Through this finding, it is proposed that green infrastructure systems can be used not only to mitigate but also as spaces to enhance local identity and economy. The research confirms the hypothesis that natural elements of the landscape can be used to develop mitigation solutions while preserving local identity. It is proposed to apply these strategies to other urban projects, such as those associated with the sustainable development of fishing coves, balancing the tensions between fishing extraction, environment, and tourism.
