Systems approach for establishing climate smart aquaculture to balance biodiversity conservation and food security in coral reef ecosystems

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...
