Environmental Management of the Coastal Boundary: Sustainable Solutions for the Green Area Deficit in Manta

This study analyzes the current state of green areas along the coastal boundary of the city of Manta, Ecuador—a zone undergoing rapid urbanization with negative consequences for environmental sustainability. Using a mixed methodological approach of a non-experimental and cross-sectional nature, which combined spatial analysis, direct observation, interviews, and regulatory review, the study identified a fragmented and limited distribution of green spaces, particularly in areas such as Playa Murciélago, Barbasquillo, and the Malecón. The results reveal high levels of environmental degradation, loss of ecosystem services, pollution, and poor ecological connectivity—factors that impact both biodiversity and citizen well-being. Furthermore, the study identified uncontrolled urbanization, persistent environmental pollution, and the effects of climate change as structural causes of the deficit. The research proposes technical and legal guidelines focused on ecological restoration and sustainable urban planning, including the implementation of green infrastructure and participatory environmental governance mechanisms. It concludes that the coordination of public policies, land-use planning, and citizen participation is essential to revalue the coastal landscape as a common good of high ecological, cultural, and social value, thereby ensuring a fairer and more resilient urban development for the city of Manta.
