Areas of expertise

Background

Adrian started his career at the National Institute of Agricultural Engineering at Silsoe, Bedfordshire (later becoming Silsoe Research Institute). This started with research into odour control from animal manures (following his PhD at the University of Glasgow) and then progressed into a wide range of experimentally-based agri-environmental research including: biological treatment systems, silage conservation, gaseous emission measurement and control and improved manure management methods. He later concentrated more on mathematical modelling, initially using process models. He later joined the Biomathematics Group leading work in whole-farm agri-environmental modelling and more recently moved into environmental Life Cycle Assessment (LCA).

He moved to Cranfield University in January 2006 to develop the LCA work, which has expanded rapidly since then and addressed subjects from livestock health to national dietary change. Much work is directed towards GHG emissions, but he likes to remind the world that there are other features of our effect on the wider environment that need quantification.

Current activities

Dr Adrian Williams' project portfolio includes projects for Defra and others in which Environmental Life Cycle Assessment (LCA) and systems modelling of agricultural and horticultural commodities is applied and developed. This includes the effects of improving health in cattle on greenhouse gas (GHG) emissions, improving pig husbandry.

He is Science Director in the UK Agricultural GHG Platform (www.ghgplatform.org.uk), which is improving the science to support the UK agricultural GHG inventory. He is also in project team that is delivering the working inventory. He also recently became involved with the water footprinting of livestock production.

He is a member of the Food Climate Research Network (www.fcrn.org.uk) steering group.

He recently completed work for Defra on the economic and environmental effects of moving to healthier diets.

 

Research interests include:

  • Development and application of Environmental Life Cycle Assessment (LCA) for agricultural and horticultural commodities and the food system
  • Whole system agri-environmental modelling
  • Effects of dietary change on the environment
  • More environmentally benign waste management
  • Modelling and measuring ammonia and greenhouse gas emissions (GHG) from agriculture
  • Multi stakeholder and ecosystem services evaluation
  • Water use and impacts in agriculture and food.
