PhD Studentship: Improved extreme climate indices for food security risk analysis, NERC GW4+ DTP PhD studentship for September 2025 Entry Ref 5405

About the Partnership

This project is one of a number that are in competition for funding from the NERC Great Western Four+ Doctoral Training Partnership (GW4+ DTP).  The GW4+ DTP consists of the Great Western Four alliance of the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five Research Organisation partners:  British Antarctic Survey, British Geological Survey, Centre for Ecology and Hydrology,  the Natural History Museum and Plymouth Marine Laboratory.  The partnership aims to provide a broad training in earth and environmental sciences, designed to train tomorrow’s leaders in earth and environmental science.

Project Aims and Methods

The increasing occurrence and severity of extreme climate events globally poses significant challenges to agriculture and food security. However, there is a limited understanding of these impacts and how to quantify them effectively. While empirical approaches have been attempted and dynamic process-based models explored, both methods have shown limitations in accurately representing extreme event impacts on crop yields. Preliminary research by the supervisory team, which integrates production and trade data with novel agroclimatic indices, has highlighted the difficulties in accurately capturing yield shocks at the national level. 
This studentship aims to develop improved climate indices to assess extreme event impacts on agriculture, thereby supporting resilience and adaptation planning.

The project will:

1. evaluate existing impact indices and models for their effectiveness in explaining changes in food security,
2. develop and demonstrate improved assessment methods using case studies across various geographies, and
3. apply these methods to future impact assessments to support risk management.

UK crop yields will be the focus of the research, with opportunities to extend the analysis internationally. The project will also contribute to the enhancement of climate observations and models, with the student encouraged to develop their own research ideas within the project scope. 

Project partners

The Met Office will meet any extra expenses (travel, subsistence) incurred by the student while working at the Met Office. There is also time and expertise delivered by the two Met Office co-supervisors (Pete Falloon and Catherine Bradshaw). 

Training

The DTP offers funding to undertake specialist training relating to the student’s specialist area of research.
