Dr. Doug Warner BSc MSc PhD PIEMA FHEA
Senior Research fellow

Tel.: +44 (0)1707 286075

Doug joined the Agriculture and the Environment Research Unit (AERU) as a Research Fellow in July 2001. His main areas of interest are agricultural greenhouse gas emissions and their mitigation, carbon sequestration, integrated farm management and ecologically based methods of pest control, precision agriculture and farmland bio-diversity and conservation.

Since 2001 he has been involved in several national and European projects undertaking carbon footprinting, life-cycle analysis, and environmental impact and sustainability assessments.  Recent activities include the modelling of spatially explicit greenhouse gas emissions in European agricultural systems, and their application for assessing the impact of European Rural Development Programmes on greenhouse gas mitigation and the development of carbon footprinting tools. Other experience includes the evaluation of the impact of insecticides on non-target organisms, herbicide dispersal on hard surfaces in urban environments, ecological monitoring, applied conservation habitat management and insect taxonomy.


Doug has a BSc in Environmental Biology from the University of Sunderland, an MSc in Crop Protection from the Scottish Agricultural College (University of Aberdeen), and a PhD from the University of Hertfordshire in collaboration with IACR-Rothamsted titled "The Potential of Carabidae in the Control of Insect Pests of Winter Oilseed Rape". His Doctorate studied naturally occurring beneficial insects as pest control agents in winter oilseed rape and the implications for Integrated Pest Management systems. Doug is also an IEMA (Institute of Environmental Management and Assessment) Associate, and a Fellow of the Higher Education Academy (HEA).

Previous employment

Doug has worked previously as a group leader with the British Trust for Conservation Volunteers, a warden with English Nature and as an insect taxonomist at IACR-Rothamsted.
