Bending the Curve of Global Freshwater Biodiversity Loss: An Emergency Recovery Plan

BioScience, Год журнала: 2020, Номер 70(4), С. 330 - 342

Опубликована: Янв. 9, 2020

Despite their limited spatial extent, freshwater ecosystems host remarkable biodiversity, including one-third of all vertebrate species. This biodiversity is declining dramatically: Globally, wetlands are vanishing three times faster than forests, and populations have fallen more twice as steeply terrestrial or marine populations. Threats to well documented but coordinated action reverse the decline lacking. We present an Emergency Recovery Plan bend curve loss. Priority actions include accelerating implementation environmental flows; improving water quality; protecting restoring critical habitats; managing exploitation ecosystem resources, especially species riverine aggregates; preventing controlling nonnative invasions; safeguarding river connectivity. recommend adjustments targets indicators for Convention on Biological Diversity Sustainable Development Goals roles national international state nonstate actors.

Area-based conservation in the twenty-first century

Nature, Год журнала: 2020, Номер 586(7828), С. 217 - 227

Опубликована: Окт. 7, 2020

Humanity will soon define a new era for nature—one that seeks to transform decades of underwhelming responses the global biodiversity crisis. Area-based conservation efforts, which include both protected areas and other effective area-based measures, are likely extend diversify. However, persistent shortfalls in ecological representation management effectiveness diminish potential role stemming loss. Here we show how expansion by national governments since 2010 has had limited success increasing coverage across different elements (ecoregions, 12,056 threatened species, 'Key Biodiversity Areas' wilderness areas) ecosystem services (productive fisheries, carbon on land sea). To be more successful after 2020, must contribute effectively meeting goals—ranging from preventing extinctions retaining most-intact ecosystems—and better collaborate with many Indigenous peoples, community groups private initiatives central biodiversity. The long-term requires parties Convention Biological Diversity secure adequate financing, plan climate change make far stronger part land, water sea policies. conservation—including measures—after 2020 depend securing funding prioritizing management.

People have shaped most of terrestrial nature for at least 12,000 years

Proceedings of the National Academy of Sciences, Год журнала: 2021, Номер 118(17)

Опубликована: Апрель 19, 2021

Significance The current biodiversity crisis is often depicted as a struggle to preserve untouched habitats. Here, we combine global maps of human populations and land use over the past 12,000 y with data show that nearly three quarters terrestrial nature has long been shaped by diverse histories habitation Indigenous traditional peoples. With rare exceptions, losses are caused not conversion or degradation ecosystems, but rather appropriation, colonization, intensification in lands inhabited used prior societies. Global history confirms empowering environmental stewardship peoples local communities will be critical conserving across planet.

The biodiversity and ecosystem service contributions and trade-offs of forest restoration approaches

Science, Год журнала: 2022, Номер 376(6595), С. 839 - 844

Опубликована: Март 17, 2022

Forest restoration is being scaled up globally to deliver critical ecosystem services and biodiversity benefits; however, there a lack of rigorous comparison cobenefit delivery across different approaches. Through global synthesis, we used 25,950 matched data pairs from 264 studies in 53 countries assess how climate, soil, water, wood production services, addition biodiversity, compares range tree plantations native forests. Benefits aboveground carbon storage, water provisioning, especially soil erosion control are better delivered by forests, with compositionally simpler, younger drier regions performing particularly poorly. However, exhibit an advantage production. These results underscore important trade-offs among environmental goals that policy-makers must navigate meeting forest commitments.

Human impacts on global freshwater fish biodiversity

Science, Год журнала: 2021, Номер 371(6531), С. 835 - 838

Опубликована: Фев. 19, 2021

No waters left untouched We are increasingly aware of human impacts on biodiversity across our planet, especially in terrestrial and marine systems. know less about fresh waters, including large rivers. Su et al. looked such systems globally, focusing several key measures fish biodiversity. They found that half all river have been heavily affected by activities, with only very tropical basins receiving the lowest levels change. Fragmentation non-native species also led to homogenization rivers, many now containing similar fewer specialized lineages. Science , this issue p. 835

Importance of Indigenous Peoples’ lands for the conservation of Intact Forest Landscapes

Frontiers in Ecology and the Environment, Год журнала: 2020, Номер 18(3), С. 135 - 140

Опубликована: Янв. 6, 2020

Intact Forest Landscapes ( IFL s) are critical strongholds for the environmental services that they provide, not least their role in climate protection. On basis of information about distributions s and Indigenous Peoples’ lands, we examined importance these areas conserving world's remaining intact forests. We determined at 36% within making crucial to mitigation action needed avoid catastrophic change. also provide evidence loss rates have been considerably lower on lands than other although forests still vulnerable clearing threats. World governments must recognize rights, including land tenure ensure Peoples play active roles decision‐making processes affect lands. Such recognition is given urgent need reduce deforestation face escalating change global biodiversity loss.
