Protecting the marine environment is about preserving physical and ecological functions and biodiversity, sustaining global natural processes on the planet, and addressing major future challenges such as climate change minimization and adaptation. is most important in coordinating the response to the challenges of On Securing Societal Goods and Benefits Ecosystem-based management is one of the fundamental pillars in the theoretical application of his MPA as a management tool for the marine environment. It implies a broad and comprehensive approach that considers all ecosystem components and processes, including human intervention. Therefore, MPA success must be verifiable at the ecosystem level. However, it is not easy to find indicators, causal relationships, or conceptual schemes, or assess the effectiveness of the MPA at this level where multiple factors and variables vary spatially and temporally. Marine ecosystems, particularly coastal wetlands and species such as sea grasses and mangroves, are important carbon sinks. However, human use and activity threatens to degrade these ecosystems, undermining their role as sinks and becoming sources of carbon emissions. Data have been provided on loss rates in, for example, and have been linked to lack of protection. The main goal of many MPAs is to reduce coastal ecosystem loss and protect iconic ecosystems and wetlands, thus reducing so-called “blue carbon ecosystems”, which have become a major priority for ocean management. is to protect As evidence of how MPAs can help restore important blue carbon ecosystems, Mangos and Claudot (2013) report that in a scenario in which improved marine environmental quality provides enhanced protection, Posidonia pastures will be replaced annually. We estimate a 1% to 2% increase. There is generally a consensus that visitors are willing to pay high fees to protect the marine environment, and this WTP level includes, but is not limited to, age, gender, education level, location, and occupation. May be influenced by sociodemographic characteristics, environmental awareness or personal income. MPAs are gaining increasing attention from policy makers as tools for the conservation and sustainable use of marine biodiversity. Although there is no universally accepted definition, IUCN defines MPA as “a recognized and dedicated body, through legal or other effective means, to achieve the long-term conservation of nature and associated ecosystem services. , a well-defined geographic space that is managed”. 1 By this definition, MPAs cover approximately 4.12% of the total marine environment. Under both the Convention on Biological Diversity (CBD) and the Sustainable Development Goals, parties have agreed to protect 10% of their marine and coastal areas by 2020. Despite the consequences of available policy tools to counter pressures on the marine environment, intensive exploitation of the ocean has caused significant damage to marine biodiversity and ecosystems. OECD publication Marine Protected Areas: Economics, management and effective policy mix presents insights on effective management of marine protected areas (MPAs), one of the available policy tools for the conservation and sustainable use of marine biodiversity and ecosystems To do. As the global reach of the MPA has grown over the past two decades, the collective response must be significantly expanded and strengthened. In many parts of the world there is growing awareness and awareness of the need for more MPAs and generally better management of coastal and marine environments.
