Tim Hess is Professor of Water and Food Systems at the Cranfield Water Science Institute, Cranfield University, UK. He has an internationally distinguished research profile on water-related risk and water footprinting in agrifood systems built around a strong track-record of research on the relationship between agriculture, food production and the water. He is recognised as an interdisciplinary research scientist, bringing together areas of natural and social sciences to address real-world problems associated with agrifood systems. Recently, his work has focused on the field of water footprinting and water-related risk, particularly in the agriculture, food and beverage sector. He is leading the UK GFS project ‘Increasing resilience to water-related risk in the UK fresh fruit & vegetable system’. He has worked on several projects considering; the contribution of water footprinting to national food policy; benchmarking irrigation water use amongst farmers and growers; and evaluating new technologies for agricultural water management. He represented the UK on the International Organisation for Standardisation (ISO) Expert Group on Water Footprinting and was co-author of the International Standard (ISO14046) and an editor for the supporting technical report (ISO/TR14073). He is a member of the Water Footprinting Technical Advisory Group for the Livestock Environmental Assessment and Performance partnership of the UN Food & Agriculture Organisation (FAO).
