Aquatic ecosystems, encompassing freshwater systems such as rivers, lakes, and wetlands, as well as marine environments including oceans, estuaries, and coral reefs, play a critical role in maintaining ecological balance and supporting human livelihoods. These ecosystems provide essential services such as water purification, nutrient cycling, climate regulation, and habitat for a vast diversity of species. However, aquatic ecosystems face multiple threats including overfishing, pollution, habitat destruction, invasive species, and the impacts of climate change. In response to these challenges, international initiatives have emerged to promote conservation, sustainable management, and restoration of aquatic environments. Two significant international initiatives aimed at the conservation of aquatic ecosystems are the Convention on Biological Diversity (CBD) and the Ramsar Convention on Wetlands. The Convention on Biological Diversity, established in 1992 at the Earth Summit in Rio de Janeiro, is a legally binding international treaty with three primary objectives: the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising from genetic resources. The CBD recognizes the integral role of aquatic ecosystems in global biodiversity and encourages nations to develop national strategies and action plans for the conservation and sustainable use of aquatic resources. The convention emphasizes the importance of protecting habitats, regulating the exploitation of species, and integrating biodiversity considerations into sectoral policies such as fisheries, agriculture, and tourism. One of the key mechanisms under the CBD is the establishment of protected areas, including marine and freshwater reserves, to safeguard critical habitats and maintain ecological processes. Additionally, the CBD facilitates the exchange of
