Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss

Global forest cover is shrinking, conservation of key biodiversity areas has stalled, and species extinction is accelerating. Desertification, land and soil degradation, drought and deforestation are further threatening ecosystems and development prospects. While more countries are adopting legal frameworks for biodiversity and environmental protection, overall progress on Goal 15 remains slow, with significant gaps in safeguarding healthy land and ecosystems vital to humanity. The conferences of the Parties to the United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa and to the Convention on Biological Diversity have helped to mobilize resources and advance global objectives to support conservation and restoration, sustainable forest management and nature-based solutions that promote resilience, livelihoods and inclusion. The Kunming-Montreal Global Biodiversity Framework, adopted in 2022, has renewed momentum for implementation.

Targets 15.1 and 15.2 - Global forest area continues to decline, although at a slower rate than in previous decades. The proportion of forest cover to total land area decreased from 31.9 per cent in 2000 to 31.2 per cent in 2020. However, sustainable forest management is improving, with an increase in the proportion of forests under management plans and within protected areas. 

Targets 14.5, 15.1 and 15.4 - Globally, average protection of key biodiversity areas increased from approximately 25 per cent in 2000 to approximately 44 per cent in 2024 across marine, terrestrial, freshwater and mountain biomes. However, progress has largely stagnated since 2015. 

Target 15.5  - Changes in aggregate species’ extinction risk, measured using the International Union for Conservation of Nature Red List Index, show a deterioration of greater than 12 per cent from 1993 to 2024 (and 4 per cent since 2015). The most severe deterioration is seen in Central and Southern Asia and Eastern and South-eastern Asia.

Target 15.6  - As at 2024, 76 countries (up from 5 countries in 2015) and 97 countries (up from 12 countries in 2015) reported about their legislative, administrative or policy measures under the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from Their Utilization to the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture, respectively. 

Target 15.9  - Country implementation of the international statistical standard to measure the environment and ecosystems and their connection to the economy increased by 36 per cent from 2017 to 2024. Although growth has slowed in recent years, adoption is expected to rise, as the standard supports key indicators in the Kunming-Montreal Global Biodiversity Framework.

SDG 15 underscores the critical importance of biodiversity as humanity’s life-support system. Yet, the relentless depletion of forests, coupled with an alarming rate of species extinction and stagnation in safeguarding key biodiversity areas, jeopardizes the delicate balance of our ecosystems. To address the pressing global environmental challenges and crises, including climate change, biodiversity loss, and pollution, as well as desertification, land and soil degradation, drought and deforestation, it is imperative to intensify efforts in fulfilling our global environmental and biodiversity commitments =.

Targets 15.1 and 15.2: The world’s forest area continues to decline, albeit at a slightly reduced pace compared to previous decades. The proportion of forest cover to total land area decreased from 31.9% in 2000 to 31.2% in 2020 with agricultural expansion accounting for nearly 90% of global deforestation. However, there has been notable progress towards sustainable forest management, marked by an increase in the proportion of forests under management plans and within protected areas. Moreover, certified forest area, which had shown steady long-term growth, has experienced a significant decline in the last two years, attributed to suspension of certificates due to the conflict in Europe.

Targets 14.5, 15.1 and 15.4: Global protected and conserved area coverage of marine, terrestrial, freshwater and mountain key biodiversity areas showed substantial improvements prior to 2000, this growth has stagnated over the last two decades. Particularly worrying is Central, Southern and Western Asia, Northern Africa, and Oceania, where average protected and conserved area coverage of key biodiversity areas is less than 30%. Progress has been more positive in Northern America and Europe, Sub-Saharan Africa, Latin America and the Caribbean, and Australia and New Zealand, where over 40% of each key biodiversity area is now covered on average.

Target 15.5: Species extinction risk continues to worsen, as evidenced by a 12% deterioration in the aggregate Red List Index between 2024 and 1993 (and 4% since 2015). The extinction risk of the world’s amphibian species was recently comprehensively re-assessed, revealing that for amphibians, climate change impacts, habitat conversion and alien invasive fungal disease are the most severe drivers of increasing extinction risk.

Target 15.6: Countries continue to make progress in ratifying and implementing access and benefit-sharing instruments. By the end of 2023, 75 countries (up from 6 countries in 2016) and 93 countries (up from 12 countries in 2015) had reported on their legislative, administrative or policy measures under the Nagoya Protocol and the International Treaty on Plant Genetic Resources for Food and Agriculture, respectively.

Target 15.7.1/15.c.1: Estimates available for the first time show that, globally, intercepted illegal wildlife trade as a proportion of all wildlife trade (legal and illegal) increased from 2017 onwards, reaching its highest levels during the COVID-19 pandemic in 2020-2021. It is estimated that wildlife seizures made up around 1.4 to 1.9% of global wildlife trade in 2020-2021.

Target 15.9: In 2023, 90 countries implemented the international statistical standard to measure the environment and ecosystems and their connection to the economy, an increase of 30% since 2017.

The world is facing a triple planetary crisis of climate change, pollution and biodiversity loss. The trend in forest loss, land degradation and the extinction of species is becoming worse, posing a severe threat to the health of the planet and people. Goal 15 will not be met without a dramatic shift in our relationship with our natural environment.

• Target 15.2: The world’s forest area continues to decline, from 31.9% in 2000 to 31.2% in 2020, representing a net loss of 100 million hectares. Agricultural expansion is the direct driver for almost 90% of global deforestation. However, globally, there has been progress in sustainable forest management with both certified forest area and the proportion of forests under management plans and within protected areas increasing.
• Targets 14.5, 15.1, and 15.4: Globally, coverage over recent years of marine, terrestrial, freshwater, and mountain KBAs has continued to increase to nearly half of each site covered in 2022, on average, but growth in coverage has slowed and coverage is uneven regionally, threatening progress towards the restoration and conservation of these ecosystems.
• Target 15.3: Between 2015 and 2019, the world lost at least 100 million hectares of healthy and productive land every year, affecting food and water security globally. Human activities, intensified by climate change, are the main drivers of land degradation, directly affecting 1.3 billion people. If land degradation continues at a similar rate, this would result in an additional 1.5 billion hectares of degraded land by 2030. To reach the target of ensuring a land degradation neutral world by 2030, avoiding new land degradation and restoring at least one billion degraded hectares of land are needed.
• Target 15.5: Species extinction is irreversible, and thus perhaps the most fundamental human impact on nature. Globally, the Red List Index-- derived based on repeat assessments of every species across groups of mammals, birds, amphibians, corals, and cycads- deteriorated by about 4% from 2015 to 2023. However, over the last three decades since 1993, the Index has deteriorated 10%, with each decade deteriorating at a faster rate than the previous one. In 2022, comprehensive assessments of reptile species found that 21% of species are threatened with extinction. All indications are a deterioration in trend toward the target to halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species.
• Target 15.6: At the end of 2022, 68 countries had at least one legislative, administrative or policy measure in place to ensure the fair and equitable sharing of benefits arising from the use of genetic resources and associated traditional knowledge in accordance with the Nagoya Protocol (an increase of 62 countries since 2016). Furthermore, 88 countries reported measures in place to implement the International Treaty on Plant Genetic Resources for Food and Agriculture (an increase of 76 countries since 2015).
• Target 15.8: Nearly all countries have now adopted national legislation relevant to the prevention or control of invasive alien species, mainly embedded within laws regarding cross-cutting sectors such as Animal Health, Plant Health, Fisheries and Aquaculture; and 87% have aligned to global targets. The COVID-19 pandemic has brought an increased focus on the prevention, control, and management of biological invasions of pathogenic agents, particularly zoonotic pathogens, in order to mitigate their negative impacts on biodiversity and human health
• Target 15.9: There has been a steady upward trend in the number of countries incorporating biodiversity values into national accounting and reporting systems. By December 2022, most countries (90%) had established national targets in relation to Aichi Biodiversity Target 2. However, only about a third of countries are reporting that they are on track to reach or exceed their national targets. In addition,92 countries indicated implementation of the System of Environmental-Economic Accounting (SEEA) in 2022 and the number of countries is expected to grow over the next few years due to the role of SEEA in the Global Biodiversity Framework.

Continued global deforestation, land and ecosystem degradation, and biodiversity loss pose major risks to human survival and sustainable development. Even as efforts are made in the domain of sustainable forest and natural resource management, commitments and instruments designed to protect, restore and sustainably use forests and biodiversity need to be urgently implemented to ensure healthy, resilient societies.

The world’s forest area continues to decrease but at a slightly slower rate compared with previous decades. The proportion of forest area fell from 31.9 per cent of total land area in 2000 to 31.2 per cent of total land area in 2020. Despite the overall loss of forest, the world continues to progress towards sustainable forest management. Between 2010 and 2020, the share of forests under certification schemes, the proportion of forest within a protected area and the proportion of forests under a long-term management plan increased globally.

Safeguarding key biodiversity areas through the establishment of protected areas or other effective area-based conservation is an essential contribution towards Sustainable Development Goals 14 and 15. Globally, this coverage of marine, terrestrial, freshwater, and mountain key biodiversity areas has increased from about one quarter of each site on average covered by protected areas 20 years ago to nearly half of each site covered in 2021.

Vegetation coverage of the world’s mountains remains roughly stable at approximately 73 per cent since 2015. Disaggregated data by mountain class shows that green cover tends to decrease with mountain elevation, evidencing the strong role of climate in mountain green cover patterns.

By February 2022, 129 countries had committed to setting their voluntary targets for achieving land degradation neutrality, and in 71 countries, Governments had already officially endorsed those targets. Overall, commitments to land restoration are estimated at 1 billion ha, out of which over 450 million ha are committed through land degradation neutrality targets.

The Red List Index shows continuing deterioration in terms of species extinction risk around the world, based on repeated assessments of the extinction risk of all amphibians, birds, mammals, corals and cycads, representing about 25,000 species in total. The index went from 0.80 in 2000 to 0.72 in 2022. The prevalence and rate of extinction risk are particularly severe in Central and Southern Asia, Eastern and South-Eastern Asia and small island developing States. COVID-19 pandemic impacts on species extinction risk are likely negative mainly because of reduced conservation capacity and resources, along with increased threats.

At the end of 2021, 68 countries had at least one legislative, administrative or policy measure in place to ensure the fair and equitable sharing of benefits arising from the use of genetic resources and associated traditional knowledge in accordance with the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from Their Utilization to the Convention on Biological Diversity. Furthermore, 79 countries reported measures in place to implement the International Treaty on Plant Genetic Resources for Food and Agriculture.

Nearly all countries (98 per cent) have adopted national legislation relevant t o the prevention or control of invasive alien species, although there is wide variation in the coverage of this legislation across sectors.

There has been a steady upward trend in the number of countries incorporating biodiversity values into national accounting and reporting systems. Most countries have established national targets in relation to Aichi Biodiversity Target 2 of the Strategic Plan for Biodiversity 2011–2020. However only about one third of countries are reporting that they are on track to reach or exceed their national targets. Despite progress, Target 2 was not met by 2020.

As of March 2022, 89 countries and territories had implemented the System of Environmental-Economic Accounting (SEEA) to make nature count in policies and build back better through accounts for natural resources and/or ecosystems. This number is unchanged from 2021. Four countries started compiling the newly adopted SEEA Ecosystem Accounting in 2021.

In 2021, a total of 234 biodiversity-relevant taxes are in force, spanning 62 countries. While these policy instruments provide incentives for sustainable consumption and production and thus to conserve and sustainably use biodiversity, they also generated revenue in the order of $8.9 billion per year (2017–2019 average).

In 2020, the official development assistance of members of the Development Assistance Committee of the Organisation for Economic Co-operation and Development in support of biodiversity was $7.2 billion, an increase of 3 per cent in real terms over 2019.

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

While the rate of deforestation in tropical regions has slowed in the past decad e, vigilance and targeted efforts are required to maintain this trend. The proportion of forest area fell from 31.9 per cent of total land area in 2000 to 31.2 per cent 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 decreased significantly 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, and 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, an average of 43 per cent of each terrestrial key biodiversity area, 42 per cent of each freshwater key biodiversity area, and 41 per cent of each mountain key biodiversity area were within protected areas, an increase of 13 to14 percentage points since 2000.

As of February 2021, 127 countries and territories had committed to setting voluntary targets for achieving land degradation neutrality, and 68 countries and territories had already officially endorsed their targets. Overall, commitments to la nd restoration are estimated to amount to 1 billion hectares, of which 450 million hectares are covered by commitments through land degradation neutrality targets.

Data based on satellite imagery reveal that green coverage (forests, grasslands, croplands and wetlands) of the world’s mountains remained steady at about 73 per cent between 2000 and 2018. Green cover tends to be greater in mountain areas that are less than 2,500 metres above sea level. However, mountain green cover varies considerably across geographical regions, ranging from 100 per cent in Oceania to 68 per cent in Northern Africa and Western Asia.

Globally, the risk of species extinction has increased by about 10 per cent over the past three decades. The Red List Index, which ranges from a value of 1 to indicate no risk of extinction to a value of 0 to indicate the extinction of all species, decreased from 0.81 in 1993 to 0.73 in 2021.

As at 1 February 2021, 128 countries, territories and the European Union had ratified the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity, which is an increase of 60 countries and territories since 2016, and 67 countries, territories and the European Union have shared information on their Nagoya Protocol frameworks. There are now 148 parties to the International Treaty on Plant Genetic Resources for Food and Agriculture, and so far, 57 countries and territories have provided information about the measures that they have taken to implement the Nagoya Protocol.

The pandemic and the vast subsequent harm 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, such as the market for ivory, which has decreased 3.5-fold since 2013, other species are under increasing threat as offenders shift their focus to more lucrative products, such as pangolin scales. In 2018, for example, there was a tenfold increase in the number of whole pangolin equivalents seized since 2014.

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

As of March 2021, 89 countries and territories have implemented the system of environmental economic accounting, an increase of 29 per cent since 2017. Of these, 62 countries and territories (70 per cent) have integrated the system of accounting into their regular statistical production methods, and compile and publish the accounts on a regular basis.

In 2019, ODA from Development Assistance Committee members provided in support of biodiversity amounted to $6.6 billion, a decrease of 14 per cent in real terms compared to 2018. In 2021, a total of 232 biodiversity-relevant taxes are in force across 62 countries and territories.

Forest areas continued to decline, protected areas were not concentrated in areas of key biodiversity and species remained threatened with extinction. However, Efforts were gaining traction and having positive effects that could help to reverse those outcomes, such as increased progress towards sustainable forest management; gains in protected area coverage for terrestrial, freshwater and mountain areas; and progress in implementing programmes, legislation and accounting principles to protect biodiversity and ecosystems.

The proportion of forest area fell, from 31.9 per cent of total land area in 2000 to 31.2 per cent in 2020, representing a net loss of nearly 100 million ha of the world’s forests. From 2000 to 2020, forest area increased in Asia, Europe and Northern America, while significantly decreasing in Latin America, sub-Saharan Africa and South-Eastern Asia, driven by land conversion to agriculture. Notwithstanding the overall loss, 2017 data showed that the proportion of forests in protected areas and under long-term management plans, as well as certified forest area, increased or remained stable at the global level and in most regions of the world.  

In 2020, the average proportion of each key biodiversity area for terrestrial, freshwater and mountain biodiversity within protected areas was 44, 41 and 41 per cent, respectively, an increase of around 12 to 13 percentage points since 2000. However, most key biodiversity areas still have incomplete or no coverage by protected areas.

As at 2019, 123 countries had committed themselves to setting their voluntary targets for achieving land degradation neutrality, and in 60 countries, governments had already officially endorsed those targets. 

Species extinction, which threatens sustainable development and compromises global heritage, is driven primarily through habitat loss from unsustainable agriculture, harvest and trade; deforestation; and invasive alien species. Globally, the species extinction risk has worsened by about 10 per cent over the past three decades, with the Red List Index (which measures the risk of extinction, whereby a value of 1 indicates no threat of extinction and a value of 0 indicates that all species are extinct) declining, from 0.82 in 1990 to 0.75 in 2015 to 0.73 in 2020.

As at 1 February 2020, 122 countries and the European Union had ratified the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity  (an increase of 53 from 2019), and 63 countries and the  European Union had shared information on their access and benefit-sharing frameworks. Regarding the International Treaty on Plant Genetic Resources for Food and Agriculture, there are now 146 contracting parties thereto, and 56 countries have provided information about their access and benefit-sharing measures.

Only about a third of reporting parties are on track to achieving their national biodiversity targets as reported in national reports under the Convention on Biological Diversity. As at January 2020, 129 parties, including the European Union, had reported their sixth national report, and 113 parties had assessed progress towards their national targets related to Aichi Biodiversity Target 2. About half the parties had made progress towards their targets, but not at a rate that will allow them to meet their goals.

There are some encouraging global trends in protecting terrestrial ecosystems and biodiversity. Forest loss is slowing down, more key biodiversity areas are protected and more financial assistance is flowing towards biodiversity protection. Yet, the 2020 targets of Sustainable Development Goal 15 are unlikely to be met, land degradation continues, biodiversity loss is occurring at an alarming rate, and invasive species and the illicit poaching and trafficking of wildlife continue to thwart efforts to protect and restore vital ecosystems and species.

• Protecting important sites for terrestrial and freshwater biodiversity is vital for ensuring long-term and sustainable use of terrestrial and freshwater natural resources. The global mean percentage of each key biodiversity area covered by protected areas increased from 33.1 per cent in 2000 to 46.1 per cent in 2018 for terrestrial areas, from 30.5 per cent in 2000 to 43.2 per cent in 2018 for freshwater areas, and from 32.9 per cent in 2000 to 44.7 per cent in 2018 for mountain areas.
• Healthy mountain ecosystems are fundamental to ensuring the provision of ecosystem services to upland communities as well as lowland peoples. As of 2017, 76 per cent of the world’s mountain areas were covered by a form of green coverage: 41 per cent by forests, 29 per cent by grassland/shrubland and only 6 per cent by cropland.
• From 2000 to 2015, more than one fifth of the Earth’s total land area was degraded, largely due to human-induced processes, such as desertification, cropland expansion and urbanization. During the same period, there were significant productivity declines in land cover, with grasslands incurring some of the greatest losses.
• The most fundamental and irreversible human impact on nature is species extinction. The Red List Index – which measures the risk of extinction, in which a value of 1 indicates no threat to any species, and a value of 0 indicates that all species are extinct – has deteriorated from 0.82 in 1993 to 0.73 globally in 2019.
• The Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity creates incentives to conserve and sustainably use genetic resources and biodiversity. As at 1 February 2019, 116 countries had ratified the Nagoya Protocol (an increase of 46 since 2016) and 61 countries had shared information on their access and benefit-sharing frameworks through the Access and Benefit-Sharing Clearing-House (representing an increase of 55 countries).
• In 2017, bilateral ODA in support of biodiversity was $8.7 billion, an increase of 15 per cent in real terms over 2016.

Protection of forest and terrestrial ecosystems is on the rise, and forest loss has slowed. That said, other facets of terrestrial conservation continue to demand accelerated action to protect biodiversity, land productivity and genetic resources and to curtail the loss of species.

• The Earth’s forest areas continue to shrink, down from 4.1 billion hectares in 2000 (or 31.2 per cent of total land area) to about 4 billion hectares (30.7 per cent of total land area) in 2015. However, the rate of forest loss has been cut by 25 per cent since 2000–2005.
• About one fifth of the Earth’s land surface covered by vegetation showed persistent and declining trends in productivity from 1999 to 2013, threatening the livelihoods of over one billion people. Up to 24 million square kilometres of land were affected, including 19 per cent of cropland, 16 per cent of forest land, 19 per cent of grassland and 28 per cent of rangeland.
• Since 1993, the global Red List Index of threatened species has fallen from 0.82 to 0.74, indicating an alarming trend in the decline of mammals, birds, amphibians, corals and cycads. The primary drivers of this assault on biodiversity are habitat loss from unsustainable agriculture, deforestation, unsustainable harvest and trade, and invasive alien species.
• Illicit poaching and trafficking of wildlife continues to thwart conservation efforts, with nearly 7,000 species of animals and plants reported in illegal trade involving 120 countries.
• In 2016, bilateral ODA in support of biodiversity totalled $7 billion, a decrease of 21 per cent in real terms from 2015.

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.

• Preserving diverse forms of life on land requires targeted efforts to protect, restore and promote the conservation and sustainable use of terrestrial and other ecosystems. Goal 15 focuses specifically on managing forests sustainably, restoring degraded lands and successfully combating desertification, reducing degraded natural habitats and ending biodiversity loss.
• Between 1990 and 2015, the world’s forest area diminished from 31.7 per cent of the world’s total land mass to 30.7 per cent. The loss was mainly attributable to the conversion of forest to other land uses, such as agriculture and infrastructure development. Meanwhile, other areas were transformed into forests through planting, landscape restoration or the natural expansion of forest. Owing to the balance of the two processes and efforts to slow deforestation, the global net loss of forest area declined from 7.3 million hectares per year in the 1990s to 3.3 million hectares per year during the period from 2010 to 2015.
• To safeguard places that contribute significantly to global biodiversity, protected areas have been established and identified as key biodiversity areas. In 2014, 15.2 per cent of the world’s terrestrial and freshwater environments were covered by protected areas. The percentage of terrestrial key biodiversity areas covered by protected areas has increased, from 16.5 per cent in 2000 to 19.3 per cent in 2016. Over the same period, the share of freshwater key biodiversity areas that are protected has increased from 13.8 per cent to 16.6 per cent, and the share of mountain key biodiversity areas under protection has grown from 18.1 per cent to 20.1 per cent.
• The focus in Goal 15 on halting biodiversity loss comes at a critical time, since many species of amphibians, birds and mammals are sliding towards extinction. According to the International Union for Conservation of Nature’s Red List Index, amphibians are declining most rapidly in Latin America and the Caribbean, primarily as a result of the chytrid fungal disease, one of numerous wildlife diseases on the rise worldwide. The greatest extinction risks for birds and mammals are found in South-Eastern Asia, mainly owing to the conversion of lowland forests. However, their decline is not inevitable, with extinction risks for vertebrate species having been reversed in five small island developing States (the Cook Islands, Fiji, Mauritius, Seychelles and Tonga) as a result of conservation actions over the past several decades.
• Conservation efforts can also be thwarted by poaching and the trafficking of wildlife. Since 1999, at least 7,000 species of animals and plants have been detected in illegal trade, and the list of species under international protection continues to grow. Comparing the size of legal trade in wildlife products (about 900,000 transactions per year) to the quantity of wildlife seized (about 16,000 seizures per year) provides an indication of the scope of illicit wildlife trafficking.
