Disease-related crop losses threaten UK potato production, with £50 million spent annually controlling late blight alone. Potato cyst nematodes further endanger the seed industry. Genomic tools, particularly diagnostic Resistance gene enrichment Sequencing (dRenSeq), have transformed resistance breeding. Our research generated high-resolution disease resistance gene profiles for 657 commercial cultivars and 200 wild accessions worldwide. This resource informs parental selection, enables strategic stacking of resistance genes against major pests and diseases, and accelerates marker development.
Mycotoxins are toxic fungal food contaminants which pose an emerging health risk and major cost to cereal production. Regulatory mycotoxin limits in food are developed by the EU and UK, and significant data gaps exist in mycotoxin occurrence and risk factors impacting prevalence. This project has demonstrated frequent mycotoxin occurrence in Scottish cereals and cereal foods. Data on occurrence of regulated mycotoxins and mycotoxin metabolites have been submitted to the Food Standards Agency and Food Standards Scotland as well as the European Food Safety Authority.
Work undertaken in SRUC-E2-2 (Reimagined policy futures: Shaping sustainable, inclusive and just rural and island communities in Scotland) has reviewed the evolution of rural policies and policy approaches in Scotland. This work has informed policy design in Scotland - particularly the forthcoming Rural Delivery Plan and recently launched Rural Assessment Toolkit - and beyond, including the guidance that has been issued by the European Commission to shape the rural proofing activities of Member States, and by the WHO and OECD on rural proofing in global contexts.
Estimating future behaviours is a key uncertainty in policy planning. Farming practice adoption work has mainly focused on farmers, often ignoring how the practice would fit in the farm operations and the role of policy and industry. We are investigating how the ADOPT tool (https://adopt.csiro.au/), which considers these aspects, can be useful in policy planning and how, and whether, it can aid comparative discussions on policy interventions. We selected two practices of high interest for Scottish Government: cover crops and 3-NOP.
Scottish hill and upland sheep are adapted to produce high-quality protein from poor-quality marginal land. With increased focus on climate change, efficiency and environmental impact of livestock production, “Breeding and managing Scottish hill sheep to meet future economic, environmental and climatic challenges” assesses genetic selection and/or crossbreeding, alongside management strategies, to achieve these goals.
Through Diageo funding from 2023-2025 we undertook soil health testing across Scotland (20 farms and 80 fields) utilising biological, chemical and physical indicators of soil health. Ongoing and historic research within the strategic research programme supported the development of these agricultural soil health indicators and guided sampling. Developed indicators have been validated on our research platforms (for example the Centre for Sustainable Cropping and organic amendment platform) and at plot scales, supporting the deployment of robust indicators at farm and field scales.
Reform of Scottish Agricultural policies imply environmental objectives are incorporated within traditional goals of food security and farm income viability. However, setting realistic but ambitious targets across economic, environmental, and biophysical dimensions remains a major challenge for policymakers. We present work using four years of the Farm Business Survey data showing the use of estimation approaches to identify best practices across income, environmental and food security domains. This covers a range of methods, from estimation-based approaches to novel applications of machine learning.
C4 WP4 research provides robust evidence to accelerate Scotland’s transition from single-use to reusable packaging. A national study on returnable packaging identified adoption-ready consumer segments, key behavioural barriers, and the packaging attributes that shape decisions. Complementary experiments on single-use cups demonstrated that a 25–30p charge can halve disposable use. Together, these findings specify charge thresholds, deposit structures, and targeting strategies.
This research project focusses on understanding the social and behavioural aspects of transition to a circular economy in Scotland. The project aims to better understand the dynamics of behaviour change over time from the perspective of individuals, households and organisations. A lack of data on uptake of household circular economy behaviours and an absence of available validated instruments to measure uptake across relevant behaviours led to the development of the Circular Behaviours Scale, drawing on knowledge of best practice in psychometric methods.
An advanced toolkit of statistical methods enables quantification of hidden spread of pests and diseases in Scotland making best use of limited data. It estimates costly-to-measure characteristics and produces risk assessments to target control efforts. Insights support non-academic partners, including advice to Scottish Forestry on great spruce bark beetle spread related to changes to the West of Scotland Pest Free Area. Through EPIC, findings are informing Scottish Government policy colleagues on threats from African swine fever to livestock and the highly pathogenic avian influenza outbreak in UK poultry.
