One-sixth of the global terrestrial surface now falls within protected areas (PAs), making it essential to understand how far they mitigate increasing pressures on nature which characterize Anthropocene. In by largest analysis this question date and not restricted forested PAs, we compiled data from 12,315 PAs across 152 countries investigate their ability reduce human pressure varies with socioeconomic management circumstances. While many show positive outcomes, strikingly find that compared matched unprotected areas, have average reduced a compound index change over past 15 y. Moreover, in tropical regions cropland conversion has increased inside even more than areas. However, our results also confirm previous studies forest where are increasing, but less counterfactual Our high national-level development scores experienced lower rates increase y outside area. caution against rapid establishment new without simultaneously addressing conditions needed enable success.

Widespread shortfalls in protected area resourcing undermine efforts to conserve biodiversity

Frontiers in Ecology and the Environment, Journal Year: 2019, Volume and Issue: 17(5), P. 259 - 264

Protected areas ( PA s) are a key tool in efforts to safeguard biodiversity against increasing anthropogenic threats. As signatories the 2011–2020 Strategic Plan for Biodiversity, 196 nations pledged support expansion extent of global estate and quality management. While this has resulted substantial increases designations, many sites lack resources needed guarantee effective conservation. Using management reports from 2167 s (with an area representing 23% terrestrial estate), we demonstrate that less than quarter these report having adequate terms staffing budget. data on geographic ranges 11,919 vertebrate species overlapping our sample s, estimate only 4–9% amphibians, birds, mammals sufficiently represented within existing estate, when adequately resourced considered. continued world's is necessary, shift emphasis quantity critical effectively respond current crisis.

Challenges and opportunities of area-based conservation in reaching biodiversity and sustainability goals

Biodiversity and Conservation, Journal Year: 2021, Volume and Issue: 31(2), P. 325 - 352

Abstract Area-based conservation is essential to safeguard nature’s diversity. In view of expanding human land use, increasing climate change and unmet targets, area-based requires efficiency effectiveness more than ever. this review, I identify relate pressing challenges promising opportunities for effective efficient protected area governance management, enhance research, decision-making capacity building in under uncertain future developments. reveal that management particularly challenged by change, invasive species, social, political economic limitations. Protected often lacks the continuous availability data on current states trends nature threats. Biocultural conservation, climate-smart biosecurity approaches help overcome induced needs, respectively. Economic valuation shifts funding priorities can boost efficiency. In-situ monitoring techniques, remote sensing open infrastructures fill information gaps planning management. Moreover, adaptive an auspicious concept framework systematic ensure enduring areas despite unpredictable Post-2020 international biodiversity sustainable development goals could be met earlier if were effective. consequently conclude with need a global system support synthesizing at local level.

Improving biodiversity protection through artificial intelligence

Nature Sustainability, Journal Year: 2022, Volume and Issue: 5(5), P. 415 - 424

Published: March 24, 2022

Over a million species face extinction, urging the need for conservation policies that maximize protection of biodiversity to sustain its manifold contributions people. Here we present novel framework spatial prioritization based on reinforcement learning consistently outperforms available state-of-the-art software using simulated and empirical data. Our methodology, CAPTAIN (Conservation Area Prioritization Through Artificial INtelligence), quantifies trade-off between costs benefits area protection, allowing exploration multiple metrics. Under limited budget, our model protects substantially more from extinction than areas selected randomly or naively (such as richness). achieves better solutions with data alternative software, meeting targets reliably generating interpretable maps. Regular monitoring, even degree inaccuracy characteristic citizen science surveys, improves outcomes. intelligence holds great promise improving sustainable use biological ecosystem values in rapidly changing resourcelimited world.

Governments recently adopted new global targets to halt and reverse the loss of biodiversity. It is therefore crucial understand outcomes conservation actions. We conducted a meta-analysis 186 studies (including 665 trials) that measured biodiversity over time compared under action with suitable counterfactual no action. find in two-thirds cases, either improved state or at least slowed declines. Specifically, we interventions targeted species ecosystems, such as invasive control, habitat reduction restoration, protected areas, sustainable management, are highly effective have large effect sizes.
