The world has four years left to achieve the Convention on Biological Diversity (CBD) Kunming–Montreal Global Biodiversity Framework Target 3, which calls for the conservation of at least 30% of planet Earth by 2030 (the 30×30 target). This global effort requires countries to acknowledge and support a wide range of governance systems that deliver sustained biodiversity outcomes within and beyond protected areas.

Ocean sustainability demands interdisciplinary knowledge. While interdisciplinary collaborations involving the natural sciences are common, few have also included the ocean humanities despite the entanglement of human culture and history with the ocean. We
a team of both ocean scientists and humanities researchers outline a framework for integrating these disciplines. We show how

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.

Tropical forests enhance regional rainfall but a robust analysis of this benefit is lacking. Consequently, the rainfall generating services of tropical forests are rarely accounted for in policymaking. We synthesised observational and model-based values of the reduction in rainfall due to tropical deforestation to quantify rainfall generation. Across these studies, we estimate that each meter squared of forest contributes 240 ± 60 L each year to regional rainfall. The Amazon forest has an even stronger rainfall benefit, with each meter squared of forest contributing 300 ± 110 L each year.

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.
