David Ellison is a Researcher/Consultant who works as an External Expert for the Swedish University of Agricultural Sciences (SLU, Umea), and as an Independent Senior Researcher (Ellison Consulting). His work focuses broadly on the science, politics and policy of climate, and primarily on forests and their relevance for climate and policy. Forest-water dynamics and how these impact moisture vapor transport and water availability across terrestrial space, as well as the potential role for forests in climate change mitigation and adaptation, form one research focus. Carbon accounting practices in Land Use, Land Use Change and Forestry (LULUCF) in the international United Nations Framework Convention on Climate Change (UNFCCC) policy frameworks, as well as regional and national climate policy frameworks, form another. He is the lead author of several articles on Forests and Water, and LULUCF carbon accounting practices in Global Environmental Change, Global Change Biology, Environmental Science & Policy and other journals.
