Project proposal details

Please look carefully through the proposal details below. If you are interested in the project then contact the supervisor, explaining why you are interested and any background which makes you a good fit for the project.

If this is an external project, the lead supervisor may have suggested someone at Imperial College or the NHM who could act as an internal supervisor and you should also contact them. If the project is external and no internal has been proposed then you must find an internal supervisor before starting the project.

Please pay close attention to any extra notes on requirements (such as being able to drive or to speak particular languages) or the application process. There may be specific limitations on the project availability: if there are then they will be clearly shown further down the page.

Project title
Climate change and coffee: are rising temperatures increasing the severity of fungal disease on coffee in east and central Africa?
Contact name
Tim Barraclough
Project based at
Silwood Park (Imperial)
Project description
Food security is an important challenge for human populations worldwide. Nearly 50% of crop yields globally are lost to pests and diseases, and reducing these losses is essential for meeting the United Nations Sustainable Development Goal 2 to “end hunger, achieve food security and improved nutrition, and promote sustainable agriculture.” Fusarium is a highly diverse clade of fungi associated with 80% of all crops. Specifically, this MSc project will look at sustainable disease management for Fusarium xylarioides, which causes a devastating wilt disease to Africa’s two most valuable coffee cash crop species.

We know that climate change will affect climatic suitability for coffee within its current regions of production in east and central Africa1. Increases in temperature and changes in precipitation patterns will decrease yield, reduce quality and increase disease pressure2. This project will be in collaboration with CABI Egham, a partner not-for-profit organisation working on food security and pest management. It will examine historic climatic changes and use these to test differences in pathogenicity in different fungal strains. The first part of this project will involve using GIS and Rstudio to analyse historic climatic changes in coffee-growing regions, with the second part using this information to design and set up in vitro fungal growth assays, with the possibility of temperature-driven infection assays in plants.

Techniques:

Data science: GIS, Rstudio programming

Mycology: fungal growth assays, pathogenicity assays

NB depending on COVID-19 restrictions, the lab-based component could be replaced by further GIS and/ or genomic analyses with a bioinformatics component instead.
