Ten percent of the world's population depend on the ocean for a readily accessible source of protein and employment, with the majority (95%) living in developing countries. Poor coastal communities are at the frontier for climate change impacts, compounded by population growth and food demand, but are among the least resilient to the challenges of the future. SOLSTICE-WIO will focus on coastal communities in nine developing countries and island states in eastern Africa, interlinked culturally and ecologically and collectively known as the Western Indian Ocean (WIO) region. All nine (South Africa, Mauritius, Seychelles, Kenya, Tanzania, Mozambique, Somalia, Madagascar, Comoros) are on the list of Official Development Aid recipients, with five identified as Least Developed Countries. In the WIO over 100 million people live within 100 km of the ocean, with a significant proportion employed in local fisheries. This leaves the region highly dependent on the ocean for economic stability, food security, and social cohesion. These coastal communities have limited adaptive capacity to cope with dramatic reductions in fish stocks caused by overfishing, habitat destruction, and increasing environmental pressures - all aggravated by climate change. The decline of WIO fisheries has had profound socio-political ramifications, from the rise of piracy to general political instability. A clear example of the devastating effect of a fish stock reduction is the collapse of the Chokka Squid fishery in South Africa. SOLSTICE-WIO will use this as a case study to demonstrate the strengths of a holistic approach to human-ecosystem-fisheries research and the potential solutions this can offer. The squid fishery was the 4th most valuable fishery in South Africa, bringing foreign currency into one of the poorest provinces. It was directly employing 5000 fishermen with 30,000 dependents. The 2013 crash had a devastating effect on the Eastern Cape, yet the underlying reasons are unknown: local fishermen believe the collapse was caused by environmental change. Until the mechanisms behind the collapse are understood, there is little potential for aiding recovery or guiding adaptation. SOLSTICE-WIO will provide this urgently needed understanding to help inform the fishery and Government as to the fate of the local ecosystem, whether it will recover, and whether the crash could have been predicted or prevented. How will SOLSTICE achieve this? The key to stability of living marine resources lies in an ecosystem approach to fisheries (EAF), which sees human-natural systems as a whole, integrated entity rather than separately considering individual target species. Simply put: you cannot manage something you don't understand, nor can you adapt to change through management improvements unless you can describe, measure and understand the changes. The core strength of SOLSTICE-WIO lies in its integral approach to food security, drawing on UK expertise in physical oceanography, marine ecology, autonomous observations, environmental economics and the human dimension,and WIO expertise in fisheries, the marine economy and regional policy development. SOLSTICE will provide the region with the state-of-the-art technology to deliver cost-effective marine research and provide the information needed to achieve maximum potential from the region's living marine resources. In the UK marine robotics, ocean models and novel data products from satellite observations have developed rapidly in the last decade, and now underpin Blue Economies and Ocean Governance in Europe. These technologies are highly agile and ready to be applied in the developing world as cost-effective ways to maximise understanding and sustainable exploitation of living marine resources. Such "technology leapfrogging" can overcome the severe lack of research ships in the WIO and save decades of effort in developing predictive modelling systems from scratch.

Over 70% of the earth's surface is ocean. As a global population, we are entirely reliant upon a healthy ocean: it contributes to the renewal of freshwater; it absorbs over a quarter of global carbon dioxide, and it produces half the oxygen we breathe. The ocean has the potential to make significant contributions to sustainable development. Many developing countries already depend on their ocean resources for food, work and livelihoods. Yet we are reaching an ocean health crisis: cumulative pressures such as over-exploitation of its resources, ocean plastics and pollution and climate change, all compounded by multiple competing uses, are pushing the ocean ecosystem to a tipping point. There is an urgent need for more integrated ocean governance, to ensure greater balance between ocean conservation and sustainable use (Sustainable Development Goal 14) and realise the ocean's potential to contribute to poverty reduction, human health, healthy ecosystems on land, climate change mitigation and adaptation, equitable economic growth and decent employment. "We are the sea...we must wake up to this ancient truth...It is time to create things for ourselves, to create established standards of excellence that match those of our ancestors." It is with this spirit that the ONE OCEAN Hub will transform our response to the urgent challenges facing our ocean. The Hub will weave learning from the ocean, and traditional knowledge of the peoples who rely upon it, with scientific excellence, innovative legal approaches and artistic methods. Our aim is to bridge the disconnections in law, science and policy across all levels from the local to the international. We aim to empower vulnerable communities, woman and youth in the blue economy and catalyse the inclusive and integrated governance approaches required to ensure a healthy ocean and flourishing communities and economies. The Hub will specifically address the challenges of South Africa, Namibia, Ghana, Fiji and Solomon Islands in realising the economic, socio-cultural and environmental benefits from the ocean. It aims to support these countries' efforts towards developing a sustainable and fair blue economy by providing new scientific data and tools to engage different sectors and groups within society, particularly vulnerable communities, woman and youth, in identifying opportunities, risks and trade-offs to: i) prevent and mitigate negative development impacts connected to the ocean, ii) participate in traditional and emerging ocean activities, and iii) predict the socioeconomic benefits of ocean conservation. The Hub pioneers integrating law and arts, policy, informatics, education, history, anthropology, and philosophy to provide targeted advice on coherent and flexible, pro-poor and gender- sensitive, climate-proofed and transparent laws and policies across the areas of environmental, human rights, science and technology, trade and investment. The Hub will further integrate biology, physics, chemistry, oceanography, ecology, mathematics, socio-environmental sciences and law to advance understanding of sustainable fisheries in the face of climate change impacts, as well as socio-economic and cultural considerations. The Hub will also increase understanding of conservation and extraction options for deep-sea mineral, biological and freshwater resources, integrating biology, ecology, geology, socio-environmental sciences and law. Through innovative use of arts the hub will transcend traditional boundaries in policy, law, and between ocean stakeholders from local communties to international organisatons, to respectfully and effectively include local communities' traditional knowledge in decision-making at the national and local level on the blue economy. The Hub will develop the integrated governance frameworks and strengthen the capacity within commnities to drive innovative approaches to a fair and sustainable blue economy for South Africa, Namibia, Ghana, Fiji and Solomon Islands
