This paper will survey how things have changed over nearly 50 years of operational research (OR) applied to agriculture. The first ‘OR group’ was set up at the National Institute of Agricultural Engineering by Dan Boyce in 1969 and is now at Cranfield University. It will examine how, and what, factors have influenced the type of work and the method...

Modelling is key to adapting agriculture to climate change (CC), facilitating evaluation of the impacts andefficacy of adaptation measures, and the design of optimal strategies. Although there are many challenges tomodelling agricultural CC adaptation, it is unclear whether these are novel or, whether adaptation merely addsnew motivations to old ch...
Article
Full-text available
Responses to future changes in climatic and socio-economic conditions can be expected to vary between sectors and regions, reflecting differential sensitivity to these highly uncertain factors. A sensitivity analysis was conducted using a suite of impact models (for health, agriculture, biodiversity, land use, floods and forestry) across Europe wit...
Article
Full-text available
The Paris Agreement established the 1.5 and 2 °C targets based on the recognition “that this would significantly reduce the risks and impacts of climate change”. We tested this assertion by comparing impacts at the regional scale between low-end (< 2 °C; RCP2.6) and high-end (> 4 °C; RCP8.5) climate change scenarios accounting for interactions acro...
Article
Full-text available
The European Union Effort Sharing Regulation (ESR) will require a 30% reduction in greenhouse gas (GHG) emissions by 2030 compared with 2005 from the sectors not included in the European Emissions Trading Scheme, including agriculture. This will require the estimation of current and future emissions from agriculture, including dairy cattle producti...

This policy booklet, High-End Climate Change in Europe, is based on “work in progress” by researchers from the IMPRESSIONS, HELIX and RISES-AM projects.
Article
Full-text available
The global land system is facing unprecedented pressures from growing human populations and climatic change. Understanding the effects these pressures may have is necessary to designing land management strategies that ensure food security, ecosystem service provision and successful climate mitigation and adaptation. However, the number of complex,...

Socio-economic drivers and additional model outputs.
Article
Full-text available
Grassland-based ruminant production systems are integral to sustainable food production in Europe, converting plant materials indigestible to humans into nutritious food, while providing a range of environmental and cultural benefits. Climate change poses significant challenges for such systems, their productivity and the wider benefits they supply...
Article
Full-text available
Climate change has the potential to impair livestock health, with consequences for animal welfare, productivity, greenhouse gas emissions, and human livelihoods and health. Modelling has an important role in assessing the impacts of climate change on livestock systems and the efficacy of potential adaptation strategies, to support decision making f...
Conference Paper
Full-text available
Farm-scale models quantify the cycling of nitrogen (N) and carbon (C) so are powerful tools for assessing the impact of management-related decisions on greenhouse gas (GHG) emissions, especially on dairy cattle farms, where the internal cycling is particularly important. Farm models range in focus (economic, environmental) and the detail with which...
Article
Full-text available
Studies of climate change impacts on agricultural land use generally consider sets of climates combined with fixed socio-economic scenarios, making it impossible to compare the impact of specific factors within these scenario sets. Analysis of the impact of specific scenario factors is extremely difficult due to prohibitively long run-times of the...
Technical Report
Full-text available
Ammonia (NH3) emissions to the atmosphere increased significantly during the 20th century, largely due to the intensification of agricultural production. Ammonia is a soluble and reactive gas that is emitted by volatilization from various agricultural nitrogen forms including urea, uric acid and mineral fertilizers. Emissions are dependent on vario...
Chapter
Full-text available
Climate change mitigation and adaptation have generally been considered in separate settings for both scientific and policy viewpoints. Recently, it has been stressed (e.g. by the latest IPCC reports) the importance to consider both mitigation and adaptation from land management together. To date, although there is already large amount of studies c...

1. Key findings This study examines the land use and greenhouse gas implications of UK food consumption change away from carbon intensive products. It shows that the UK agricultural land base can support increased consumption of plant-based products arising from the reduced consumption of livestock products. A 50% reduction in livestock product...
Article
Full-text available
This paper discusses the future of operational research (OR) for the agricultural industries in a broad sense, including horticulture and viticulture during a period of increased pressure on natural resources. The authors use their experience in the field along with published literature, to draw insights into new opportunities for OR, and how the O...
Article
Full-text available
Developing models to predict the effects of social and economic change on agricultural landscapes is an important challenge. Model development often involves making decisions about which aspects of the system require detailed description and which are reasonably insensitive to the assumptions. However, important components of the system are often l...

Full-text available
Background, aims and scope Food production is essential to life. Modern farming uses considerable resources to produce arable crops. Analysing the environmental burdens of alternative crop production methods is a vital tool for policymakers. The paper describes the production burdens (calculated by life cycle analysis) of three key arable crops: br...
Article
This group, which represents the reformed Operational Research (OR) Society's Agriculture and Related Industries group (http://www.orsoc.org.uk), promotes the use of OR (or the application of the scientific method) in solving management and governance problems within this sector. The theme of this meeting was to look at models concerned with making...
Article
This working group, which is concerned with operational research methods and applications to agricultural science in its broad meaning (i.e. including Forest Management and Fisheries), was formed in 2003 within the European Association of Operational Research Societies (EURO). The first meeting of the group was held at the former Silsoe Research In...
Article
1. Answering many of the critical questions in conservation, development and environmental management requires integrating the social and natural sciences. However, understanding the array of available quantitative methods and their associated terminology presents a major barrier to successful collaboration. 2. We provide an overview of quantitativ...

Full-text available
Environmental life cycle assessment (LCA) is a holistic way of calculating the environmental burdens resulting from the production of a commodity. It provides a way of objectively comparing alterative methods of production and, to a lesser extent, comparing commodities themselves. The two general types of burdens on the environment are resource use...
Article
Full-text available
Production of 10 major commodities in England and Wales was studied using Life Cycle Analysis (LCA). Organic and non-organic (contemporary conventional) systems were compared. Organic production was generally less energy consuming, except for poultry meat, eggs and tomatoes. Environmental burdens, such as global warming po-tential or eutrophication...

this paper, we summarise how the MEASURES Framework was constructed and give some results from the application of it, particularly for manure management on farms
Article
Full-text available
A model is described that analyses both the economic and long-term environmental performance of whole farms. The Silsoe Whole Farm Model was combined with mechanistic calculations of environmental burdens (nitrate, ammonia and nitrous oxide and methane) to produce the MEASURES Framework. MEASURES responds to changes in soil type, rainfall and farm...
Article
Full-text available
An environmental Life Cycle Assessment (LCA) procedure is constructed to compare the total emissions from different techniques for managing livestock wastes. Life Cycle Assessment is a method of holistically and systematically accounting for the environmental benefits and burdens of the production of goods and services including consequential burde...
Article
The options for abating ammonia emissions from livestock buildings and waste stores under UK conditions have been assessed. There is increasing interest in reducing such emissions, which contribute to long-range atmospheric pollution problems, and which, via subsequent deposition, can also harm sensitive ecosystems.A literature review was first car...
Article
Full-text available
Interdisciplinarity played an essential role at the foundation of Operational Research, which is itself a relatively recent inter-discipline. The interdisciplinary character of OR has not thrived since due in part to pressures within a predominantly mono- disciplinary academia. The need for interdisciplinarity never went away and is now gaining mor...
Article
Jerome believed that the task of the commentator was to convey what others have said, not to advance his own interpretations. However, an examination of his commentaries on the Prophets shows that their contents are arranged so as to construct a powerful, but tacit, position of authority for their compiler. By juxtaposing Jewish and Greek Christian...
