Progress and Info

Deforestation and forest degradation, continued biodiversity loss, and the ongoing degradation of ecosystems, are having profound consequences for human wellbeing and survival. The world fell short on 2020 targets to halt biodiversity loss. The COVID-19 pandemic has confirmed that by threatening biodiversity, humanity threatens its own survival. While great efforts are being made on expanding sustainable forest management, increasing coverage of key biodiversity areas, and signing up to legislation and treaties to protect biodiversity and ecosystems, much more needs to be done to put the health of the planet at the centre of all our plans and policies.

While the rate of deforestation has slowed down in the last decade in tropical regions, vigilant targeted efforts are still required to maintain this trend. The proportion of forest area fell from 31.9% of total land area in 2000 to 31.2% in 2020, representing a net loss of almost 100 million hectares of the world’s forests. From 2000 to 2020, forest area increased in Asia, Europe and Northern America, but significantly decreased in Latin America and sub-Saharan Africa. Despite the losses in forest cover, above-ground forest biomass per hectare, the proportion of forest area in protected areas and under long-term management plans, as well as certified forest area all increased or remained stable at the global level and in most of the regions of the world, demonstrating global progress towards sustainable forest management.

In 2020, on average, 43% of each terrestrial Key Biodiversity Area (KBA), 42% of each freshwater KBA, and 41% of each mountain KBA were within protected areas, an increase of around 13-14 percentage points since 2000.

As of February 2021, 127 countries had committed to set their voluntary targets for achieving land degradation neutrality, and in 68 countries, governments had already officially endorsed these targets. Overall, commitments to land restoration are estimated at 1 billion hectares, out of which 450 million hectares are committed through land degradation neutrality targets.

Data based on satellite imagery reveals that the world's mountain's green coverage (forests, grasslands, croplands and wetlands) has remained stable, hovering at about 73% between 2000 and 2018. Green cover tends to be higher in mountain areas below 2,500 meters above sea level. However, mountain green cover varies considerably across geographical regions; ranging from 100% in Oceania to 68% in Northern Africa and Western Asia.

Globally, species extinction risk has worsened by about 10% over the last three decades, with the Red List Index (which ranges from a value of 1 indicating no risk of extinction to a value of 0 indicating all species are extinct) declining from 0.81 in 1993 to 0.73 in 2021.

As of 1 February 2021, 128 countries and the EU had ratified the Nagoya Protocol on Access and Benefit-sharing (ABS) (an increase of 60 countries since 2016) and 67 countries and the EU have shared information on their ABS frameworks. Regarding the International Treaty on Plant Genetic Resources for Food and Agriculture, there are now 148 Contracting Parties, and 57 countries have thus far provided information about their ABS measures.

The COVID-19 pandemic and the vast subsequent harms to human and economic well-being have starkly illustrated the potential global impact of zoonotic diseases, for which wildlife trade – both legal and illegal - is a potential vector. While certain markets for illegal wildlife products are declining, like that for ivory (decreased by 3.5-fold since 2013), other species are under increasing threat as offenders shift their focus to more lucrative products like pangolin scales. There was, for example, in 2018 a 10-fold increase in the number of whole pangolin equivalents seized since 2014.

Nearly all countries (98%) have adopted national legislation relevant to the prevention or control of invasive alien species, although there is wide variation in the coverage of this legislation across sectors. The proportion of countries aligning their invasive alien species-related targets with global targets has increased, from 74% in 2016 to 84% in 2020.

As of March 2021, 89 countries and territories have implemented the System of EnvironmentalEconomic Accounting (SEEA), an increase of 29% from 2017. And 62 countries and territories (or 70%) have integrated the SEEA into their regular statistical production and compile and publish the accounts on a regular basis.

In 2019, DAC members’ ODA in support of biodiversity was $6.6 billion, a decrease of 14% in real terms over 2018. In 2021, a total of 232 biodiversity-relevant taxes are in force, spanning 62 countries.
