Today's protected areas: supporting a more sustainable future for humanity

Abstract

Nature provides significant benefits to people, especially those living in and around protected areas. Ecosystem services from protected areas include producing wild food, supporting biodiversity and water cycles, regulating climate, and providing cultural services like better health, tourism, and legacy for future generations. In economic terms, the flows of ecosystem services provided by protected areas are worth hundreds of billions of dollars each year, well justifying the costs of managing these sites, but protected areas are suffering from environmental problems such as impacts from human population growth, rural poverty, growing demands for natural resources, land use change that degrades ecosystem productivity, invasive non-native species that harm natural ecosystems, and climate change that is affecting all ecosystems. Addressing these linked challenges will require mobilizing all parts of the economy, including the protected area estate. For example, protected areas can take a leadership role in rural development, expand the conservation estate to half of the planet through connectivity and improved management of more of the non-agricultural land, enhance the prominent role of protected areas in contributing to climate change mitigation and adaptation, encourage productive research on applying modern technology to protected areas management, seek broader private sector participation in conserving biodiversity and ecosystem services, and include protected areas as relevant parties in relevant trade and other international negotiations. When protected area managers embrace this broader role, they will find enthusiastic public support for this contribution to a sustainable human society.
