Protected Areas
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; t ...
