Nadeem’s research focuses on the effects of forestry on the water environment with the over-arching aim of protecting and enhancing water quality and resources.

In a general sense the research is concerned with forest-water interactions and the function of trees in the hydrological cycle. More specifically it is about the hydrochemical changes associated with forest operations such as planting and felling, both in terms of negative impacts but also the benefits that woodlands bring to the water environment. The work links to international focus areas within integrated catchment management including diffuse pollution mitigation, peatland restoration, natural flood management and aquatic carbon transport.

In addition to the applied research, Nadeem has a number of projects with academic partners conducting basic research that aims to improve our understanding of natural processes in forested environments, particularly in relation to the hydrological and global biogeochemical cycles.

The provision of forests and water related advice to government agencies, academic institutions, research providers and industry is a key component of his work.
