Synopsis (short abstract) This report presents a baseline study to evaluate the potential for cross-sector cooperation as a significant work strand under the “Deep-Seas Fisheries under the Ecosystem Approach” (DSF Project) component of the 2nd Phase of the GEF Common Oceans Programme. Deep-sea fisheries (DSF) in areas beyond national jurisdiction (ABNJ) occur at depths between 200 and 2 000 metres, and typically require large vessels, long periods at sea, and target species with a high market value. The demersal and benthic species targeted vary from region to region but are often fished on specific areas of continental slopes and isolated topographic features (e.g. oceanic seamounts). Many deep-sea fish are long-lived, slow-growing, and mature at a relatively old age. The low resilience and high vulnerability of these species means that individual marine sectors and the cumulative impact of human activities can adversely affect fish populations for whom fisheries management is regulated by deep-sea regional fisheries management organizations (dsRFMOs). A desk study to screen and scope marine sectors (in a timeframe up to 2050) revealed varying impacts on deep-sea fish, deep-sea habitats, deep-sea food webs (upon which the fish depend), and/or deep-sea fishers.

    Deep-sea fisheries bring economic benefits and are an important source of employment, livelihoods and nutrition. Yet, stock depletion is a major challenge while impacts on ecosystems raise environmental concerns. The Common Oceans Deep-sea fisheries project is committed to making deep-sea fisheries in the ocean areas beyond national jurisdiction (ABNJ) more sustainable and reducing their ecological footprint.

    Review of the implementation of the International Guidelines for the Management of Deep-sea Fisheries in the High Seas 2024

    The International Guidelines for the Management of Deep-sea Fisheries in the High Seas (DSF Guidelines) were adopted by FAO in 2008. The first and only review of the implementation of the Guidelines took place in 2010. There have been many advances in implementation since then and it is timely to conduct another review. The DSF Guidelines have been used to guide regional fisheries management organizations and states in the development of spatial management processes defining fishing grounds and protecting vulnerable marine ecosystems. The DSF Guidelines also require that harvested fish stocks and impacts on bycatch species are assessed and managed, but this has been less well implemented.

    Picturing progress – Four betters in focus 2025
    Also available in:
    This commemorative volume marks the 80th anniversary of the Food and Agriculture Organization of the United Nations (FAO), tracing its journey from a founding conviction – that hunger is not inevitable – to today’s global mission of transforming agrifood systems. Through a rich collection of photographs and narratives, the book illustrates how FAO works alongside farmers, fishers, scientists, governments, Indigenous Peoples, youth and civil society to advance sustainable solutions that nourish both people and planet.Organized around FAO’s vision of the four betters – better production, better nutrition, a better environment and a better life – the book highlights concrete progress: from regenerative farming and climate-smart livestock, to school feeding programmes, land restoration and inclusive digital innovation. It reflects on both the challenges and the opportunities facing agrifood systems, including climate volatility, conflict and inequality, while showing how collaboration, knowledge and innovation create pathways for resilience and hope.Arriving at a moment of reflection and renewal, this volume is both tribute and testimony: to the millions of people whose daily efforts sustain our world, and to FAO’s enduring commitment to building sustainable, inclusive and equitable agrifood systems that leave no one behind.
