CEH is the UK's Centre of Excellence for research in the land and freshwater environmental sciences. CEH's staff have specialist skills in a wide range of environmental disciplines, ranging from the smallest scale (the gene) to the largest scale (whole Earth systems). Our research is aimed at improving understanding both of the environment as we see it today and the natural processes that underlie the Earth's support systems - for example climate & water resources. We are particularly interested in the impacts of human activity on natural environments. We aim to generate workable solutions to today's pressing environmental problems. Our parent organisation is the UK Natural Environment Research Council.
