Association of Applied Biologists
AAB - President
Cropping and the Environment
The Group aims to develop a range of innovative meetings and events tackling key topical and strategic issues in the areas of crops and cropping systems; weed, vegetation and nutrient management and wider agri-environment issues. 

Recent subjects of conferences organised by the Group include:  What makes an alien invasive? – risk and policy responses, Agri-Environment Schemes: where do we go from here?, Measuring and Marketing the Environmental Costs and Benefits of Agricultural Practice, Biomass and Energy  Crops.


The Group is also responsible for delivering the Crop Protection in Southern Britain meeting.


We welcome ideas for conferences or other activities from AAB members; please forward these to the Group via the AAB office.   


I look forward to meeting you at one of our conferences soon.    

Rob Carlton

My principle area of engagement is in sustainable agriculture, with an emphasis on climate change, optimising land use and rational use of inputs. I am currently particularly interested in the interaction between social, economic and environmental aspects of sustainability.

I graduated as an ecologist and my doctoral researched was on plant chemical defences against insects and pathogens. I moved to industry in 1990, initially with Schering Agrochemicals in the UK investigating crop metabolism and environmental fate of crop protection products. I moved to the Frankfurt to take on a leadership role in AgrEvo’s insecticide regulatory group.  Following the formation of Aventis CropScience I moved to Lyon where I worked on registration and stewardship of insecticides, and during which period I developed a special interest in on-farm stewardship of challenging products.
In 2004 I established my own company in France.  Working closely with the newly formed Bayer CropScience I helped to co-ordinate European insecticide stewardship. Further to this I developed a professional interest in climate change and agriculture, in particular carbon accounting of arable products and systems. I continued to work with industry, most recently on sustainable farm network development. I am currently active within the Association of Applied Biologists as a trustee and convenor of the Cropping and Environment special interest group.

I consider myself to be a generalist and I aim to combine good science with common sense to determine how land resources can best be utilised to meet the needs of society.


Group Members
Kairsty Topp
My research interest lies in understanding the impact of changes in farm management in cropping / grassland systems on the environment, and in how an understanding of these issues can inform economic and social models of the farming system.

Alongside colleagues, my research addresses the global warming potential of different management systems, mitigation and adaptation strategies for farming systems, and tools to compare the sustainability of different farming systems.  I work closely with colleagues from SCRI and other European countries to develop these tools that will be crucial in the assessment of the environmental impact and economic resilience of farming systems.

Current areas of work focus on N2O emissions from grasslands and arable rotations, the assessment of the GWP of crop/arable systems at the Scottish regional level, the development of tools to aid in the assessment of, and how crop/arable systems impact of the environmental and economic sustainability of farming systems.  I also have an interest in developing methods to assess how crop morphology impacts on weed and diseases in cereal crops, and understanding the affects of management and climate on a long-term rotation.

Naomi Jones

Naomi Jones. Naomi has 25 years' research experience including management of multidisciplinary, collaborative studies. She has managed many recent evaluations of agri-environment schemes and related initiatives including current projects evaluating the new Countryside Stewardship, assessing the role of advice on HLS agreement set-up, monitoring of Entry Level Stewardship and the impact of ETIP advice and the evaluation of voluntary measures implemented under the Campaign for the Farmed Environment. Naomi is currently a member of the British Ecological Society, Association of Applied Biologists, European Weed Research Society and the UK Weed Liaison Group and was a subject Editor for Weed Research 2003-2009. She has been an Editor of two conference proceedings and is currently on the organising committee for two further conferences. Her recent research has included studies which combine ecological and wider environmental survey with socio-economic issues such as farmers' attitudes to, and understanding of, agri-environment policies and their implementation. Other areas of research include management of weeds (detrimental and beneficial) in arable systems.

Elizabeth Stockdale
I have been involved in a wide range of research projects connected with the study of nutrient cycling in soils and with the environmetnal impact of farming systems. At the smallest scale I have used isotope dilution techniques to investigate mineralisation, immobilisation and nitrification processes. The understanding gained has been used to develop modelling approaches to predict soil nutrient cycling at soil, field and farm scale and to guide fertiliser recommendation systems. I have also maintained a strong link to organic farming and carried out some research into nutrient cycling (N, P, K) in organic famring systems.


Elizabeth is also the Honorary General Secretary for the Association.
