SUSTAINABLE DEVELOPMENT GOAL 15

Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss
PROGRESS OF GOAL 15 IN 2017


Progress in preserving and sustainably using the Earth’s terrestrial species and ecosystems is uneven. The pace of forest loss has slowed and improvements continue to be made in managing forests sustainably and protecting areas important for biodiversity. However, declining trends in land productivity, biodiversity loss and poaching and trafficking of wildlife remain serious concerns.

  • The net loss of forest continues to slow and forest biomass stock per hecta re is stable. More forests are being protected and areas under long-term management plans and voluntary certification have increased. From 2010 to 2015, the annual net loss of forest area globally was less than half that of the 1990s. The proportion of land area covered by forest decreased from 31.6 per cent in 1990 to 30.8 per cent in 2010 and 30.6 per cent in 2015.

  • Fifteen per cent of land is currently under protection, but that does not cover all areas important for biodiversity. Protecting key biodiversity areas is necessary to strengthen natural resource management and biodiversity conservation. From 2000 to 2017, average worldwide coverage of terrestrial, freshwater and mountain key biodiversity areas by protected areas increased from 35 per cent to 47 per cent, from 32 per cent to 43 per cent and from 39 per cent to 49 per cent, respectively.

  • As of 2017, 76 per cent of the world’s mountain areas are covered by some form of green vegetation, including forests, shrubs, grasses and crops. Green cover on mountains is lowest in Central Asia (31 per cent) and highest in Oceania (excluding Australia and New Zealand) (98 per cent).

  • From 1998 to 2013, about one fifth of the Earth’s land surface covered by vegetation showed persistent and declining trends in productivity. South America and Africa are most affected; in some cases, advanced stages of land degradation there are leading to desertification in dryland areas, particularly in the grasslands and rangelands. Land and soil degradation undermine the security and development of all countries. Reversing the effects of land degradation and desertification through sustainable land management is key to improving the lives and livelihoods of more than 1 billion people currently under threat.

  • Biodiversity loss continues at an alarming rate according to the Red List Index. The extinction risk for corals is increasing most rapidly among all assessed species groups owing to the growing threat from climate change and local impacts. Chytrid fungal disease, another grave concern, is decimating many amphibian species and increasing their risk of extinction.

  • Wildlife poaching and trafficking continues to thwart conservation efforts. Illicit wildlife markets are complex and subject to rapid fluctuations. Demand for a given wildlife product can grow quickly, before the international community can react. In 2013, elephant ivory, rosewood and rhinoceros horn comprised over 60 per cent of total wildlife and timber product seizures.

  • The global community is committed to conserving biodiversity. Two international agreements aim at sharing the benefits from using genetic resources in a fair and equitable way. As of April 2017, 144 countries ratified the International Treaty on Plant Genetic Resources for Food and Agriculture and 96 countries ratified the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization.

  • In 2015, bilateral ODA in support of biodiversity amounted to $8.8 billion, an increase of 39 per cent in real terms over 2014.
