Area-based conservation in the twenty-first century

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.

Global impacts of future urban expansion on terrestrial vertebrate diversity

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: March 25, 2022

Abstract Rapid urban expansion has profound impacts on global biodiversity through habitat conversion, degradation, fragmentation, and species extinction. However, how future will affect needs to be better understood. We contribute filling this knowledge gap by combining spatially explicit projections of under shared socioeconomic pathways (SSPs) with datasets terrestrial (amphibians, mammals, birds). Overall, lead 11–33 million hectares natural loss 2100 the SSP scenarios disproportionately cause large fragmentation. The within current key priority areas is projected higher (e.g., 37–44% in WWF’s Global 200) than average. Moreover, land conversion reduce local within-site richness 34% abundance 52% per 1 km grid cell, 7–9 may lost 10 cell. Our study suggests an urgent need develop a sustainable development pathway balance conservation.

Overcoming the coupled climate and biodiversity crises and their societal impacts

Science, Journal Year: 2023, Volume and Issue: 380(6642)

Published: April 20, 2023

Earth's biodiversity and human societies face pollution, overconsumption of natural resources, urbanization, demographic shifts, social economic inequalities, habitat loss, many which are exacerbated by climate change. Here, we review links among climate, biodiversity, society develop a roadmap toward sustainability. These include limiting warming to 1.5°C effectively conserving restoring functional ecosystems on 30 50% land, freshwater, ocean "scapes." We envision mosaic interconnected protected shared spaces, including intensively used strengthen self-sustaining the capacity people nature adapt mitigate change, nature's contributions people. Fostering interlinked human, ecosystem, planetary health for livable future urgently requires bold implementation transformative policy interventions through institutions, governance, systems from local global levels.

Solving Brazil's land use puzzle: Increasing production and slowing Amazon deforestation

Land Use Policy, Journal Year: 2019, Volume and Issue: 91, P. 104362 - 104362

Published: Nov. 19, 2019

Brazil has become an agricultural powerhouse, producing roughly 30 % of the world's soy and 15 its beef by 2013 – yet historically much that growth come at expense native ecosystems. Since 1985, pastures croplands have replaced nearly 65 Mha forests savannas in legal Amazon. A growing body work suggests this paradigm horizontal expansion agriculture over ecosystems is outdated brings negative social environmental outcomes. Here we propose four strategies can reduce deforestation, while increasing production wellbeing. First, eliminate land grabbing speculation through designation public forests. This would clarify tenure limit pool available for uncontrolled ranching. Second, deforestation on private properties implementing existing mechanisms Brazil's Forest Code to facilitate payments services, with support from market initiatives sustainable sourcing products. Third, incentivize increased productivity medium large targeted investments. By stimulating adoption proven technologies intensification, help meet targets international demand products, without expanding into new areas. Finally, foster economic, improvements technical assistance small farmers. Small farmers occupy a swath Amazon often lack access assistance, technology, markets. Providing quality could them better align practices local opportunities; increase household income improve livelihoods; pressure. these coordinated effort between agents, show world how output, reestablishing leadership managing natural resources mitigating climate change.

Abstract We evaluate methods to calculate the economic value of protected areas derived from improved mental health visitors. A conservative global estimate using quality-adjusted life years, a standard measure in economics, is US$6 trillion p.a. This an order magnitude greater than area tourism, and two three orders aggregate management agency budgets. Future research should: refine this more precise methods; consider interactions between conservation policies budgets at national scales; examine links personalities experiences individual scale.

Mapping the irrecoverable carbon in Earth’s ecosystems

Nature Sustainability, Journal Year: 2021, Volume and Issue: 5(1), P. 37 - 46

Published: Nov. 18, 2021

Abstract Avoiding catastrophic climate change requires rapid decarbonization and improved ecosystem stewardship at a planetary scale. The carbon released through the burning of fossil fuels would take millennia to regenerate on Earth. Though timeframe recovery for ecosystems such as peatlands, mangroves old-growth forests is shorter (centuries), this still exceeds time we have remaining avoid worst impacts global warming. There are some natural places that cannot afford lose due their irreplaceable reserves. Here map ‘irrecoverable carbon’ globally identify remains within human purview manage and, if lost, could not be recovered by mid-century, when need reach net-zero emissions impacts. Since 2010, agriculture, logging wildfire caused least 4.0 Gt irrecoverable carbon. world’s 139.1 ± 443.6 faces risks from land-use conversion change.

The existing area network in Madagascar covers 10.4% its land includes at least part range majority described native species vertebrates with known distributions (97.1% fishes, amphibians, reptiles, birds, mammals combined) plants (67.7%). overall figures are higher for threatened (97.7% 79.6% occurring within one area). International Union Conservation Nature (IUCN) Red List assessments Bayesian neural identify overexploitation biological resources unsustainable agriculture as prominent threats to biodiversity. We highlight five opportunities action multiple levels ensure that ecological restoration objectives, activities take account complex underlying interacting factors produce tangible benefits people Madagascar.
