Deep reefs below 30 m provide essential ecosystem services for ocean health and human well-being such as food security and climate change resilience. Yet, deep reefs remain poorly researched and largely unprotected, including in the Western Indian Ocean (WIO). Here, we assessed current conservation approaches in the WIO focusing on deep reefs, using a combination of online surveys and semi-structured interviews. Results indicated that deep-reef data are sparse and commonly stemming from non-peer-reviewed or non-publicly available sources, and are often not used to inform conservation of WIO marine protected areas. Based on those findings, we co-developed a framework with WIO stakeholders comprising recommendations linked to specific actions to be undertaken by regional actors to improve the capacity of the region to collect and share deep-reef information. We hope this framework will enhance deep-reef stewardship and management throughout the WIO and thus aid sustainable blue economic growth in the region.

The Indo-Pacific warm pool is the warmest ocean in the world and is known as "the global heat engine," which plays an important role in the climate system.

A new study led by the University of Liverpool has found that wandering albatrosses with older partners spend less time on foraging trips than those with more sprightly partners so that their mate has a shorter wait without food.

Mass coral bleaching events are making it harder for some species of reef fish to identify competitors, new research reveals.

Introduction: Ocean fronts are moving ephemeral biological hotspots forming at the interface of cooler and warmer waters. In the open ocean, this is where marine organisms, ranging from plankton to mesopelagic fish up to megafauna, gather and where most fishing activities concentrate. Fronts are critical ecosystems so that understanding their spatio-temporal variability is essential not only for conservation goals but also to ensure sustainable fisheries. The Mozambique Channel (MC) is an ideal laboratory to study ocean front variability due to its energetic flow at sub-to-mesoscales, its high biodiversity and the currently debated conservation initiatives. Meanwhile, fronts detection relying solely on remotely-sensed Sea Surface Temperature (SST) cannot access aspects of the subsurface frontal activity that may be relevant for understanding ecosystem dynamics.

The Introduction of this paper argues that current coastal and ocean management approaches like marine spatial planning (MSP) often do not adequately acknowledge and integrate Indigenous and Local Knowledge (ILK). This is problematic because how humans value and perceive coastal and marine resources is integrally linked to how they use and manage these resources, especially in adapting to social-ecological change. Coastal and marine resources are situated within complex social-ecological systems that are culturally, economically, historically and politically embedded. Therefore, management approaches have to integrate transdisciplinary and contextual perspectives in order to be relevant, sustainable and adaptive. Following extensive research in Algoa Bay, South Africa this article highlights several pathways to bridge the gap between existing ILK and current coastal and ocean management approaches. The Methods section discusses how the authors worked in tandem with a bottom-up (engaging with Indigenous and local coastal and marine resource users) and top-down (engaging with coastal governance authorities and practitioners) approach. In order to answer the primary research question "How can ILK be integrated into area-based ocean management like MSP"? the authors employed arts-based participatory methods as well as in-depth interviews and workshops with coastal governance authorities and practitioners over several months. This work then culminated in a one-day multi-stakeholder workshop which brought both ILK holders and coastal authorities and practitioners together to collaboratively identify pathways to integrate this knowledge into coastal and ocean management. In the Results and Discussion section the authors present and discuss five co-identified pathways to integrate ILK in coastal and ocean management which include: adopting contextual approaches to coastal and ocean management; increasing transparency and two-way communication between coastal authorities and

Plastic pollution has been recorded in eight freshwater streams running into Gulf St Vincent, confirming the regular flow of microplastics into local marine environments - and the need for better waste management systems.

Kenya is committed to the global efforts on climate change mitigation and adaptation as seen through investments in various sustainable green and blue economy projects. In this review paper, we present the current status of what has been done, particularly on the blue carbon offset initiatives undertaken in the mangrove and seaweed ecosystems as well as the decarbonization activities at the port of Mombasa and which should form reference information for local, regional, bilateral/multilateral partners, scientists and other climate change stakeholders. The blue carbon offset projects involve mangrove conservation, reforestation and carbon credit sale as well as seaweed farming. The initiatives have several unique features amongst which are the community-led income generation systems that simultaneously act as an inducement for ecosystem preservation, co-management and benefits sharing which are recipes for economic, socio-cultural, and environmental sustainability. A notable project impact is the conferment of economic power to the locals, particularly the women and the youth The model used embraces a collaborative approach involving multisectoral engagements of both the government, multilateral organizations, NGOs, and local communities. This integrated top-down (government) and bottom-up (local community) method deliberately targets the strengthening of economic development while ensuring sustainability.
