Smart Efficient Energy Centre: a £7M research centre working across three low carbon energy sectors: ocean energy, nuclear energy, and energy efficient structures.
Multi-Land: Enhancing Agricultural Productivity and Ecosystem Service Resilience in Multifunctional Landscapes. A research cluster of the National Research Network for Low Carbon, Energy and Environment
ForestModelling: Modelling economic impact and strategies to increase resilience against tree disease outbreaks. ForestModelling aims to build a series of models to study the ways in which different management options can reduce risks and expected damages from a range of forest diseases. It is a project of the Tree Health and Plant Biosecurity Initiative.
Invasive Woody Plants in the Tropics: The Invasive Woody Plants in the Tropics research group, based at the University of Wales, Bangor, UK, has undertaken two major field studies in Jamaica and Tanzania, together with a global review of invasions resulting in a comprehensive database, an analysis of common characteristics and recommendations for management and control.
