Mark Johnson

Dr. Mark Johnson is working to understand how land use practices influence interactions between hydrological and ecological processes, and how these ecohydrological processes further affect ecosystem services including carbon sequestration. Unraveling interactions between the water cycle and the carbon cycle is essential for improving the sustainability of land and water management, especially under changing climatic conditions. Dr. Johnson’s research in ecohydrology demonstrates that soil carbon processes are also integrally important to the health of freshwater ecosystems and drinking water supplies. Dr. Johnson and his team are testing carbon and water cycle interactions to address questions such as: How much carbon does water transport from the land into freshwater systems? His research can also help to answer very applied questions related to soil fertility and water use such as: How much food can be produced in urban environments, and how much water would that require? To address these and other related questions, Johnson is developing innovative approaches to ecohydrological research in partnership with communities, natural resource management agencies and organizations, and industry.
