Ocean warming is increasing the frequency, extent, and severity of tropical-coral bleaching and mortality. During 2014–2017, marine heatwaves caused the Third Global Coral Bleaching Event. We analyze data from 15,066 reef surveys globally during 2014–2017. Across all surveyed reefs, 80% and 35% experienced moderate or greater (affecting >10% of corals) bleaching and mortality, respectively.

For decades, a dominant argument for protecting forests has focused on carbon. Trees absorb carbon dioxide, store it in wood and soils, and slow the accumulation of greenhouse gases. A new scientific review suggests this emphasis overlooks other ways forests shape climate and human well-being. Forests, it argues, are not only a mitigation tool for the future climate. They also help people adapt to climate change today, shaping temperature, water and human well-being in ways that are felt locally.

Meeting the ambitious targets set by the Convention on Biological Diversity (CBD) Kunming-Montreal Global Biodiversity Framework (GBF) will require expanding ecosystem restoration across governance domains for marine and coastal ecosystems. Marine spatial planning (MSP), which balances the development of multiple human uses in the ocean with the preservation of ecosystem health, might be the most effective vehicle for achieving this aim. However, to date, MSP and restoration efforts have proceeded on separate tracks, and biodiversity loss continues.

Since 2023, the Palau International Coral Reef Center (PICRC) has been collaborating with the Koror State Government (KSG) to conduct research and monitoring aimed at providing essential baseline data to guide the Koror Southern Lagoon Coastal Fisheries Management Plan, a new fisheries management initiative for Koror State. The management plan identified several fish spawning aggregation sites for protection, including the longnose emperor (melangmud, Lethrinus olivaceus) at Mutiaur.

The interlinked crises of climate change and biodiversity loss are slipping down political agendas just as geopolitical instability and fiscal pressures rise. Overseas development aid is falling in real terms, and many megadiverse countries are juggling debt stress that pushes conservation to the margins.

Mangroves are trees and shrubs that grow in saline and brackish tidal waters across tropical and subtropical regions of the world.1Mangroves support rich biodiversity spanning both marine and terrestrial environments. Their roots anchor to the sediment, providing shelter for an array of marine fauna including fish, invertebrates, and mammals. Their canopy provides habitat, food, and shelter for many terrestrial organisms, including mammals such as tigers and monkeys, birds, reptiles, and insects.

Other Effective Area-based Conservation Measures (OECMs), introduced by the Convention on Biological Diversity (CBD), refer to areas outside formal protected-area networks that deliver effective and enduring in situ biodiversity conservation. This scoping review systematically examined global approaches to identifying and evaluating potential OECMs. Analysing 99 studies covering 694 case studies and 237 000 potential sites, we found that potential OECMs are widespread, particularly in Asia and terrestrial environments, with most initiatives led by the environmental sector.

Nurturing people-nature relationships in evolving social-ecological landscapes can slow biodiversity loss and build resilient communities
Biodiversity loss is often framed as a failure of conservation. In reality, it is a failure of relationships.
