Efectos del cambio climático en la anidación de las tortugas marinas

Efectos del cambio climático en la anidación de las tortugas marinas

Abstract

<p>El aumento de la temperatura y el nivel del mar, entre otros signos de cambio climático, están afectando los patrones de distribución, alimentación, reproducción y migración de las tortugas marinas y muchos otros organismos que ya de por sí están bajo presión por actividades humanas destructivas a nivel mundial, y las hace aun más vulnerables. Costa Rica no es la excepción, sin embargo se estima que las consecuencias no serían iguales en todo su territorio. La interacción entre las placas tectónicas Coco y Caribe bajo la península de Nicoya es aparentemente la principal causa del aumento del nivel relativo del mar de 4 mm/año en esta región. Sin embargo, si el deshielo y el aumento del nivel del mar global se aceleran superando los efectos locales, como parece estar ocurriendo, se daría un aumento del nivel del mar geográficamente generalizado. Un aumento de 1 m en el nivel del mar en playa Grande, por ejemplo, implicaría un retroceso de la playa aproximado de 50 m tierra adentro. La playa e infraestructura en esa franja quedarían inmersas en el agua y serían erosionadas por el choque de la marea, y gran parte de la inundación ocurriría desde atrás, avanzando por la boca del estero Tamarindo, por los manglares que lo rodean, y otros terrenos adyacentes. Urge tomar medidas de mitigación y adaptación del cambio climático en cada localidad que reduzcan la vulnerabilidad e incrementen la resistencia y la resiliencia de los ecosistemas y sociedades humanas. El proyecto de conservación de tortugas marinas en playa Junquillal es un estudio de caso que ha generado y exportado lecciones aprendidas en el campo de la conservación comunitaria y la adaptación al cambio climático.</p>
