Protecting 1.2% of Earth would prevent most extinctions, study says

SAO PAULO, June 25 (Reuters) - Setting aside an additional 1.2% of the world's land as nature preserves would prevent the majority of predicted plant and animal extinctions and cost about $263 billion, according to a study published on Tuesday.
The world is racing to meet a goal to protect 30% of the world by 2030 to protect wildlife that is being decimated by climate change, pollution and habitat destruction.
Global policymakers will meet at a United Nations summit in Colombia in October to discuss plans for reaching that goal.
The study in the journal Frontiers in Science aimed to identify the highest value areas in hope that they be included in those protection plans, said Carlos Peres, a study co-author and conservation ecology expert at the University of East Anglia in the United Kingdom.

Conservation Imperatives: securing the last unprotected terrestrial sites harboring irreplaceable biodiversity
Abstract
Ambitious biodiversity goals to protect 30% or more of the Earth’s surface by 2030 (30x30) require strategic near-term targets. To define areas that must be protected to prevent the most likely and imminent extinctions, we propose Conservation Imperatives—16,825 unprotected sites spanning ~164 Mha of the terrestrial realm that harbor rare and threatened species. We estimate that protecting the Conservation Imperatives would cost approximately US$169 billion (90% probability: US$146—US$228 billion). Globally, 38% of the 16,825 sites are either adjacent to or within 2.5 km of an existing protected area, potentially reducing land acquisition and management costs. These sites should be prioritized for conservation action over the next 5 years as part of a broader strategy to expand the global protected area network. The expansion of global protected areas between 2018 and 2023 incorporated only 7% of sites harboring range-limited and threatened species, highlighting a renewed urgency to conserve these habitats. Permanently protecting only 0.74% of land found in the tropics, where Conservation Imperatives are concentrated, could prevent the majority of predicted near-term extinctions once adequately resourced. We estimate this cost to be from US$29 billion to US$46 billion per year over the next 5 years. Multiple approaches will be required to meet long-term protection goals: providing rights and titles to Indigenous Peoples and Local Communities (IPLCs) conserving traditional lands, government designation of new protected areas on federal and state lands, and land purchase or long-term leasing of privately held lands.
