Noncompliance regularly undermines the effectiveness of marine protected areas (MPAs) worldwide. The reasons for and drivers of noncompliance depend on the context (e.g., insufficient funding, capacity, neocolonialism, historical conflict), but the prevalent solution offered to curtail noncompliance tends to be more or better enforcement. We posit that this response is well intentioned but incomplete.

Since its initial articulation in the early 1970s, the sphere of legislative and judicial practices regarding the right to a healthy environment (R2HE) has evolved substantially. This report identifies and examines trends and developments in the interpretation of the R2HE over a decade (2015-2025) through an analysis of the advancement of the right in thirty jurisdictions, including international and regional human rights bodies.

In public finance, some costs are politely kept off the books. The ocean has long been one of them. Governments often speak of “blue growth” and “sustainable use,” yet many policies still treat marine ecosystems as a kind of free input: available, resilient, and cheap to replace. The result is ecological decline. It is also a fiscal problem. States end up assuming risks they would not tolerate on land.

Seagrass meadows might not catch the eye like coral reefs, but they play an important and often unsung role in coastal protection, particularly as climate change increasingly eats away at shorelines. Protecting and restoring seagrass meadows, experts say, is a key “nature-based solution” that can also soak up and store carbon.

Freshwater ecosystems regulate the water cycle, support biodiversity and enhance resilience, yet they remain largely overlooked in global climate policies, and most national commitments lack clear, spatially defined targets for their protection and restoration. Here our global map—derived from 30-m land-cover classification, hydrological networks and floodplain models—reveals around 51 million km2 of rivers, wetlands, headwaters, riparian buffers and floodplains that are critical for water security and disaster risk reduction.

A review of the geology, palaeontology, genetic, and morphology studies indicates that during the mid-Miocene to Pliocene, New Guinea consisted of four island Blocks (Vogelkop, Maokop, Central, and Southeastern). The initial dispersal of marsupials from Australia was into the Vogelkop Block. The ancestors of at least six genera (Dactylonax, Microperorytes, Myoictis Pseudochirops, Spilocuscus, Tous) and three species (Dendrolagus inustus, Dendrolagus ursinus, Dorcopsis muelleri) of endemic New Guinean marsupials are likely to have reached New Guinea via this route.

The core objective of the conference was to provide a cross-disciplinary space that fosters new knowledge, inspires learning, and strengthens the science–policy interface. It was also a celebration of achievements and progress in ocean science and management, as well as regional collaboration.

An ecosystem is defined as a collection of organisms that move energy within and outside of a system, while sustaining both the system itself and the multiple services that benefit humanity. Ecosystem restoration, then, is ultimately concerned with reviving and maintaining ecosystem processes by repopulating organisms and enhancing the habitat after periods of disturbance or loss.

Equitable ocean governance is critical, as the oceans are essential to the planetary system and global health.oceans cover 71% of Earth’s surface and are crucial to our planet’s life-support system. Coastal and marineecosystems extend up to 100 kilometres inland, encompass the continental shelf, and include ocean systemswith depths of up to 50 metres. the distinct marine ecosystems found in these environments include estu-arine and coastal wetlands, such as marshes and mangroves, as well as sand beaches and dunes, seagrassbeds and coral and oyster reefs.

A prosperous blue economy in coastal areas requires operational models that clearly link ecological outcomes to economic returns. These models can support investment, planning, and the growth of non-extractive economies that benefit both coastal communities and the environment. Here, we focus on an Essential Ocean Variable—fish biomass—because it is a globally standardized and monitored variable with proven links to recovery and management. We connect this variable to a key economic output: scuba diving ecotourism, which is a critical component of many coastal economies.
