This project will aim to understand impacts of climate smart sustainable mariculture as a nature-based solution (NbS) for enhancing biodiversity and food security in tropical marine ecosystems. About 1 billion people's livelihoods depend directly on coral reefs, but many countries relying on coral reef resources for sustainable development lack an integrated marine resource planning system that considers mariculture as part of delivering environmental, social, economic and food security goals. A key challenge hindering the evaluation and inclusion of mariculture national marine resource plans and strategies is a scientific knowledge gap in how mariculture interacts with the needs of people and marine biodiversity. Specifically, we lack robust socio-ecological evidence on the wider role of mariculture in coral reef conservation, food security, and sustainable livelihoods. This PhD project will co-develop key performance indicators for improving assessment and engagement with mariculture in tropical countries to enhance strategic planning of conservation of coral reef biodiversity, seafood production and community resilience in the face of climate change. We hope that the project will have direct benefits in our case study areas, and beyond. We will co-create new holistic approaches to provide scientific socio-economic and ecological evidence to enable tropical countries considering mariculture development on where best to pilot integrated multi-trophic aquaculture as nature-based solutions.Many countries dependent on coral reef ecosystems for the health of their environment (food security from vulnerable fisheries and protection from coral reefs to extreme climate events), economy (sustainable livelihoods based on fishing and tourism) and society (coastal culture, recreation and well-being) facing unprecedented challenges in extreme changes in climate (e.g., higher frequency of cyclones, hurricanes, tsunamis) and uncertain global events (financial crisis, food shortages and global pandemics) will not have access to climate smart mariculture that can offer resilience to provide economic prosperity, biodiversity conservation and employment from sustainable coral reef mariculture.The project will address the following scientific objectives: (1) How will climate change affect resilience of sustainable mariculture as a nature-based solution, especially in tropical countries where coastal communities are vulnerable to food insecurity from declining coral reef fisheries? (2) How can future scenario climate models relate to environmental-economic-social trade-offs for integrated multi-trophic aquaculture systems? (3) How do changes visualised in models enable systems approaches to inform science policy that underpin inclusive and collaborative decision-making on best locations for climate smart mariculture?

该项目旨在了解气候智能可持续海产养殖作为加强热带海洋生态系统生物多样性和粮食安全的基于自然的解决方案的影响。大约10亿人的生计直接依赖珊瑚礁，但许多依赖珊瑚礁资源实现可持续发展的国家缺乏综合海洋资源规划系统，该系统将海产养殖视为实现环境、社会、经济和粮食安全目标的一部分。阻碍评价和纳入海洋养殖国家海洋资源计划和战略的一个关键挑战是，在海洋养殖如何与人的需要和海洋生物多样性相互作用方面存在科学知识差距。具体地说，我们缺乏强有力的社会生态证据，表明海水养殖在珊瑚礁保护、粮食安全和可持续生计方面发挥着更广泛的作用。这一博士项目将共同制定关键绩效指标，以改进对热带国家海洋养殖的评估和参与，以加强珊瑚礁生物多样性保护、海产品生产和社区面对气候变化的复原力的战略规划。我们希望该项目将在我们的案例研究领域和其他领域产生直接好处。我们将共同创建新的整体方法，提供科学的社会经济和生态证据，使考虑在哪里发展海产养殖的热带国家能够最好地将综合多种营养水产养殖作为基于自然的解决方案。许多国家依赖珊瑚礁生态系统的环境健康(脆弱渔业的粮食安全和珊瑚礁免受极端气候事件的保护)、经济(以渔业和旅游业为基础的可持续生计)和社会(沿海文化、娱乐和福祉)在极端气候变化(例如，飓风、飓风、海啸频率更高)和不确定的全球事件(金融危机、气候智能水产养殖将无法提供经济繁荣、生物多样性保护和可持续珊瑚礁水产养殖的就业机会。该项目将解决以下科学目标：(1)气候变化将如何影响可持续水产养殖作为一种基于自然的解决方案的复原力，特别是在沿海社区容易受到珊瑚礁渔业衰退带来的粮食不安全影响的热带国家？(2)未来情景气候模型如何与综合多营养水产养殖系统的环境-经济-社会权衡相关？(3)模型中可视化的变化如何使系统方法能够为科学政策提供信息，从而支持关于气候智能海产养殖最佳地点的包容性和协作决策？
