Doug joined the Agriculture and the Environment Research Unit
(AERU) as a Research Fellow in July 2001. His main areas of interest are bio-diversity and
farmland conservation, integrated crop management and organic farming, the bio-control
potential of naturally occurring beneficial insects, precision agriculture, livestock /
grassland and the impact of novel farming strategies on climate change mitigation.
He has practical experience in eco-toxicological assessments of
the impact of pesticides on non-target organisms, ecological monitoring, applied
conservation habitat management and insect taxonomy. His main areas of expertise include:
- Life-cycle Analysis (LCA).
- Environmental Impact Assessment (EIA).
- Detailed management scenario construction for agricultural and
horticultural systems, and semi-natural habitats.
- Energy balance and greenhouse gas emissions inventories, carbon
sequestration.
- Application of mathematical models in the development of decision
support software.
- Nutrient balancing and the use of models to predict nitrogen
outputs.
- Socio-economic assessments (for example net and gross margins,
labour, visual impact) and application within sustainability studies.
- Informing of policy on current / proposed rural development
strategies (for example Environmental Stewardship).
Qualifications
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 an Associate 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.
