Welcome to Darren Grafius, who has recently joined the F3UES group at Cranfield. The focus of his work will be on the fifth of the main sections of the project – modelling ecosystem service production. Darren is currently designing and constructing a computer model for estimating food production in allotment gardens. While currently simple, it is intended that over time this work will scale up to form the bulk of the Urban BESS framework for modelling urban food production as an ecosystem service. He is also exploring existing models and mapping tools for ecosystem service research, as well as working out how best to organise the large amount of data being created by the project.
