Nous nous trouvons à un carrefour critique pour la gouvernance future de la haute mer, mais l'éloignement perçu de l'océan mondial crée un obstacle psychologique pour que les gens s'y engagent. Compte tenu des défis de la surexploitation, de l'accès inéquitable et d'autres préoccupations en matière de durabilité et d'équité, les mécanismes actuels de gouvernance des océans ne sont pas adaptés à leur objectif. Cette décennie offre des opportunités d'impact direct sur la gouvernance des océans, cependant, déclencher une transformation mondiale sur la façon dont nous utilisons et protégeons la moitié de notre planète nécessite un effort concerté guidé par des valeurs et des principes partagés entre les régions et les secteurs. L'objectif de la série d'ateliers décrits dans ce document était d'entreprendre un processus de réflexion sur l'avenir qui pourrait utiliser le cadre Nature Futures comme un mécanisme pour apporter plus d'énergie transformatrice dans la façon dont les humains conceptualisent la haute mer et donc comment nous visons à gouverner l'océan. Nous avons constaté que l'engagement avec l'avenir à travers des récits de science-fiction permettait une appréciation plus radicale de ce qui pourrait être et que l'infusion d'éléments artistiques dans la science peut inspirer un public au-delà du milieu universitaire. Ainsi, les efforts créatifs de coproduction qui favorisent et encouragent l'imagination pour relever les défis actuels devraient être considérés comme des outils importants dans l'interface science-politique, également comme un moyen de susciter des réponses empathiques. Cette série d'ateliers était une première étape, et, espérons-le, prometteuse, vers la génération d'une pratique plus créative dans la façon dont nous imaginons et agissons pour un avenir meilleur pour la haute mer. Nos encontramos en una encrucijada crítica para la futura gobernanza de la alta mar, pero la lejanía percibida del océano global crea una barrera psicológica para que las personas se involucren con él. Dados los desafíos de la sobreexplotación, el acceso inequitativo y otras preocupaciones de sostenibilidad y equidad, los mecanismos actuales de gobernanza de los océanos no son adecuados para su propósito. Esta década ofrece oportunidades para un impacto directo en la gobernanza de los océanos, sin embargo, desencadenar una transformación global sobre cómo usamos y protegemos la mitad de nuestro planeta requiere un esfuerzo concertado que se guíe por valores y principios compartidos en todas las regiones y sectores. El objetivo de la serie de talleres descritos en este documento era emprender un proceso de pensamiento sobre el futuro que pudiera utilizar el Marco de Futuros de la Naturaleza como un mecanismo para aportar más energía transformadora a la forma en que los humanos conceptualizan la alta mar y, por lo tanto, cómo pretendemos gobernar el océano. Descubrimos que comprometerse con el futuro a través de narrativas de ciencia ficción permitía una apreciación más radical de lo que podría ser e infundir a la ciencia elementos artísticos puede inspirar a audiencias más allá de la academia. Por lo tanto, los esfuerzos creativos de coproducción que promueven y fomentan la imaginación para abordar los desafíos actuales deben considerarse como herramientas importantes en la interfaz ciencia-política, también como una forma de obtener respuestas empáticas. Esta serie de talleres fue un primer paso, y esperemos que prometedor, hacia la generación de una praxis más creativa en la forma en que imaginamos y luego actuamos para un futuro mejor para la alta mar. We find ourselves at a critical crossroads for the future governance of the high seas, but the perceived remoteness of the global ocean creates a psychological barrier for people to engage with it. Given challenges of overexploitation, inequitable access and other sustainability and equity concerns, current ocean governance mechanisms are not fit-for-purpose. This decade offers opportunities for direct impact on ocean governance, however, triggering a global transformation on how we use and protect the half of our planet requires a concerted effort that is guided by shared values and principles across regions and sectors. The aim of the series of workshops outlined in this paper, was to undertake a futures thinking process that could use the Nature Futures Framework as a mechanism to bring more transformative energy into how humans conceptualise the high seas and therefore how we aim to govern the ocean. We found that engaging with the future through science fiction narratives allowed a more radical appreciation of what could be and infusing science with artistic elements can inspire audiences beyond academia. Thus, creative endeavours of co-production that promote and encourage imagination to address current challenges should be considered as important tools in the science-policy interface, also as a way to elicit empathetic responses. This workshop series was a first, and hopefully promising, step towards generating a more creative praxis in how we imagine and then act for a better future for the high seas. نجد أنفسنا في مفترق طرق حاسم للإدارة المستقبلية لأعالي البحار، لكن البعد المتصور للمحيط العالمي يخلق حاجزًا نفسيًا أمام الناس للتعامل معه. بالنظر إلى تحديات الاستغلال المفرط والوصول غير العادل وغيرها من شواغل الاستدامة والإنصاف، فإن آليات إدارة المحيطات الحالية ليست مناسبة للغرض. يوفر هذا العقد فرصًا للتأثير المباشر على إدارة المحيطات، ومع ذلك، فإن إحداث تحول عالمي حول كيفية استخدامنا لنصف كوكبنا وحمايته يتطلب جهدًا متضافرًا يسترشد بالقيم والمبادئ المشتركة عبر المناطق والقطاعات. كان الهدف من سلسلة ورش العمل الموضحة في هذه الورقة هو إجراء عملية تفكير مستقبلي يمكن أن تستخدم إطار عمل مستقبل الطبيعة كآلية لجلب المزيد من الطاقة التحويلية إلى كيفية تصور البشر لأعالي البحار وبالتالي كيف نهدف إلى حكم المحيط. وجدنا أن الانخراط في المستقبل من خلال روايات الخيال العلمي سمح بتقدير أكثر جذرية لما يمكن أن يكون وغرس العلم بالعناصر الفنية يمكن أن يلهم الجماهير خارج الأوساط الأكاديمية. وبالتالي، يجب اعتبار المساعي الإبداعية للإنتاج المشترك التي تعزز وتشجع الخيال لمواجهة التحديات الحالية أدوات مهمة في واجهة العلوم والسياسات، وأيضًا كوسيلة لاستنباط استجابات متعاطفة. كانت سلسلة ورش العمل هذه خطوة أولى، ونأمل أن تكون واعدة، نحو توليد ممارسة أكثر إبداعًا في كيفية تخيلنا ثم العمل من أجل مستقبل أفضل لأعالي البحار.

AbstractTo halt further destruction of the biosphere, most people and societies around the globe need to transform their relationships with nature. The internationally agreed vision under the Convention of Biological Diversity—Living in harmony with nature—is that “By 2050, biodiversity is valued, conserved, restored and wisely used, maintaining ecosystem services, sustaining a healthy planet and delivering benefits essential for all people”. In this context, there are a variety of debates between alternative perspectives on how to achieve this vision. Yet, scenarios and models that are able to explore these debates in the context of “living in harmony with nature” have not been widely developed. To address this gap, the Nature Futures Framework has been developed to catalyse the development of new scenarios and models that embrace a plurality of perspectives on desirable futures for nature and people. In this paper, members of the IPBES task force on scenarios and models provide an example of how the Nature Futures Framework can be implemented for the development of illustrative narratives representing a diversity of desirable nature futures: information that can be used to assess and develop scenarios and models whilst acknowledging the underpinning value perspectives on nature. Here, the term illustrative reflects the multiple ways in which desired nature futures can be captured by these narratives. In addition, to explore the interdependence between narratives, and therefore their potential to be translated into scenarios and models, the six narratives developed here were assessed around three areas of the transformative change debate, specifically, (1) land sparing vs. land sharing, (2) Half Earth vs. Whole Earth conservation, and (3) green growth vs. post-growth economic development. The paper concludes with an assessment of how the Nature Futures Framework could be used to assist in developing and articulating transformative pathways towards desirable nature futures.

Abstract Along the world's (sub) tropics mangroves are important coastal ecosystems supporting small-scale fisheries and human populations, highlighting the need to consider participatory approaches in this ecosystem management. We carried out a socio-ecological assessment to characterize the use and perceptions of local populations at Northeastern Brazil (Sao Francisco River Estuary) on mangrove fisheries and local development, and pointed out strategies for environmental planning. The questionnaire-based results show that the locals are economically dependent on mangrove fisheries, exploring 12 types of fish, 4 types of crabs, 3 types of mollusks and shrimps. All populations indicated a decrease in the fishery yield, mainly due to a high fishery pressure and shrimp farming. We conclude that strategies pointed out by the locals as creation of an protected area of sustainable use (Extractive Reserve), aided by government support to create a local small-scale fishery processing industry, to cultivate oysters and fish and ecotourism are sustainable alternatives for poverty alleviation and mangrove conservation. These alternatives and the socio-ecological assessment should be a guideline for other mangroves areas worldwide with similar environmental problems and where fishery is the base of economic subsistence, in order to guarantees the long term sustainability of mangrove socio-ecological systems.

AbstractOcean warming ‘hotspots’ are regions characterized by above‐average temperature increases over recent years, for which there are significant consequences for both living marine resources and the societies that depend on them. As such, they represent early warning systems for understanding the impacts of marine climate change, and test‐beds for developing adaptation options for coping with those impacts. Here, we examine five hotspots off the coasts of eastern Australia, South Africa, Madagascar, India and Brazil. These particular hotspots have underpinned a large international partnership that is working towards improving community adaptation by characterizing, assessing and projecting the likely future of coastal‐marine food resources through the provision and sharing of knowledge. To inform this effort, we employ a high‐resolution global ocean model forced by Representative Concentration Pathway 8.5 and simulated to year 2099. In addition to the sea surface temperature, we analyse projected stratification, nutrient supply, primary production, anthropogenic CO2‐driven ocean acidification, deoxygenation and ocean circulation. Our simulation finds that the temperature‐defined hotspots studied here will continue to experience warming but, with the exception of eastern Australia, may not remain the fastest warming ocean areas over the next century as the strongest warming is projected to occur in the subpolar and polar areas of the Northern Hemisphere. Additionally, we find that recent rapid change in SST is not necessarily an indicator that these areas are also hotspots of the other climatic stressors examined. However, a consistent facet of the hotspots studied here is that they are all strongly influenced by ocean circulation, which has already shown changes in the recent past and is projected to undergo further strong change into the future. In addition to the fast warming, change in local ocean circulation represents a distinct feature of present and future climate change impacting marine ecosystems in these areas.

Many coastal communities rely on living marine resources for livelihoods and food security. These resources are commonly under stress from overfishing, pollution, coastal development and habitat degradation. Climate change is an additional stressor beginning to impact coastal systems and communities, but may also lead to opportunities for some species and the people they sustain. We describe the research approach for a multi-country project, focused on the southern hemisphere, designed to contribute to improving fishing community adaptation efforts by characterizing, assessing and predicting the future of coastal-marine food resources, and co-developing adaptation options through the provision and sharing of knowledge across fast-warming marine regions (i.e. marine ‘hotspots’). These hotspots represent natural laboratories for observing change and concomitant human adaptive responses, and for developing adaptation options and management strategies. Focusing on adaptation options and strategies for enhancing coastal resilience at the local level will contribute to capacity building and local empowerment in order to minimise negative outcomes and take advantage of opportunities arising from climate change. However, developing comparative approaches across regions that differ in political institutions, socio-economic community demographics, resource dependency and research capacity is challenging. Here, we describe physical, biological, social and governance tools to allow hotspot comparisons, and several methods to evaluate and enhance interactions within a multi-nation research team. Strong partnerships within and between the focal regions are critical to scientific and political support for development of effective approaches to reduce future vulnerability. Comparing these hotspot regions will enhance local adaptation responses and generate outcomes applicable to other regions.
