The basis of the IUCN Red List of Ecosystems are the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing an ecosystem's risk of collapse. They are designed to be: broadly applicable across type ecosystems and geographic areas, transparent and ...
It produces the IUCN Red List of Threatened Species and the IUCN Red List of Ecosystems. The IUCN Red List of Ecosystems is applicable at local, national, regional, and global levels. IUCN's stated goal is to expand the global network of national parks and other protected areas and promote good management of such areas.
Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood control. Ecosystem services are grouped into four broad categories of services.
Provisioning services provide resources to humanity, such as fuel and water, while regulating services include carbon sequestration, climate regulation, and protection against disease. [26] Supporting ecosystem services include nutrient cycling, while cultural services are a source of aesthetic and cultural value for tourism and heritage. [26]
In 2019, a summary for policymakers of the largest, most comprehensive study to date of biodiversity and ecosystem services, the Global Assessment Report on Biodiversity and Ecosystem Services, was published by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). It stated that "the state of nature has ...
The term nature-based solutions was put forward by practitioners in the late 2000s. At that time it was used by international organisations such as the International Union for Conservation of Nature and the World Bank in the context of finding new solutions to mitigate and adapt to climate change effects by working with natural ecosystems rather than relying purely on engineering interventions.
A Protected Area is “a clearly defined geographical space, recognized, dedicated, and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values”. [2]
The IUCN World Parks Congress of 2003 defined ICCAs as: natural and/or modified ecosystems containing significant biodiversity values and ecological services, voluntarily conserved by (sedentary and mobile) indigenous and local communities, through customary laws or other effective means.
