Bridging the land-sea divide: links, interactions and trade-offs for food security and biodiversity

Project Outline and objectives:

Very little work has focused on linking the interactions and trade-offs among food production systems on land and sea. The combined effects of growing human population and climate impacts on ecosystems will pose significant challenges for sustainable food production in the future. To gain better understanding of alternative pathways towards sustainable futures, in depth knowledge of the interactions between agriculture, aquaculture and fisheries sectors are needed at global, regional and local scales.We propose a PhD programme which combines multisectoral information (data and models) on land and sea to determine how different industries land and sea can cross connect and put pressure on each other and the socio-ecological system overall.

More specifically the project will:

1) Identify interdependencies of fisheries, aquaculture and agriculture sectors
2) Determine how alternative external stressors (climate change, demographic change, economic drivers) propagate through and impact the overall socio-ecological system
3) Evaluate trade-offs among ecosystem services under different intensification pathways
The methods used will start by looking at global databases on current and historical uses and links. The second phase will use global models and (potentially) regional down-scaled models for specific regions to look at what future trade-offs may exist.

Collaborative links:
The project will also benefit from active collaboration with other members of the Centre for Marine Socioecology and internationally through potential collaboration with the International Institute for Applied Systems Analysis (Austria), the Inter Sectoral Impact – Model Intercomparison Project (Germany) and links with the Madingley Model developers at Microsoft Research and UNEP (Derek Tittensor, UK and Canada).
