Areas of expertise
Jerry joined Cranfield University in 1993, after completing a BSc (Hons) in Physical Geography (Plymouth Polytechnic), an MSc Land and Water Management (Silsoe College, Cranfield) and a PhD in Application of GIS for modelling agricultural water demands (Cranfield).
As a recognised international
specialist in irrigation science, Prof Knox has developed thought leadership in
three key areas (i) agricultural water resources management, (ii) climate
impacts and adaptation, and (iii) precision irrigation and resource efficiency. He also manages a research theme in water management for sportsturf through collaborative links with the Scandinavian Sportsturf and Environment Research Foundation (STERF).
Jerry has an international
research reputation in the science, engineering and management of water
resources for agriculture, including assessing the relationships
between water resources, agricultural productivity (yield) and the environment,
and the sustainability of irrigation in the context of climate change impacts and food security. His research interests are in
biophysical and water resource modelling, precision irrigation engineering,
geospatial modelling and climate impacts and adaptation in agriculture.
