Terrestrial Areas

Summary Global Guidelines Technical and interactive resources

Target 3 applies to all natural terrestrial ecosystems, plus some long-established cultural ecosystems (created through human management) with important associated biodiversity.

How to protect terrestrial areas

Key steps towards Target 3 include:

  • Ensuring that a full range of ecosystems are represented. Concern about some ecosystems, such as tropical forests, can overshadow the important biodiversity and ecosystem service values of other ecosystems, such as native grasslands, woodlands, savannah and tundra.
  • Emphasizing a mosaic. Terrestrial protected areas need to be integrated both with conservation of inland waters and of coastal and marine systems, and with ecological corridors and sustainable management in the rest of the landscape.
  • Choosing the optimal management. Many protected areas, and even more Other Effective Area-based Conservation Measures (OECMs), support a variety of uses, but these sites are not sustainable use areas. Navigating what is and is not compatible with conservation is a key challenge in the Global Biodiversity Framework (GBF) and at the site-level where monitoring and adaptive management will need to be employed to ensure management is effective.
  • Many of these points are applicable to marine and inland waters as well.



Enabling factors and challenges

Pressures on terrestrial ecosystems are huge and increasing. Intensive agriculture is the largest driver of ecosystem loss and creates threats from fertilizer and pesticide pollution. Human population changes can threaten traditional, biodiversity-friendly management. Success therefore depends on wider social and technical changes including restoration, dietary change, the future of pastoralism, rural migration and climate change.

Area-based conservation needs to plan for future development and seek to shape how this evolves. Some countries could find it hard to establish large new terrestrial protected areas. The Convention on Biological Diversity (CBD) requires OECMs to conserve significant biodiversity and obtain rightsholders’ consent, but there are fears OECMs will be recognized in places of little conservation value and will harm human rights.

This element of Target 3 interacts with many other GBF targets including particularly Target 7 on pollution reduction, Target 10 on sustainability of agriculture and Target 16 on consumption.
