Article
CONTEXT: Agroforestry is gaining interest in in Europe however the trade-offs associated with its uptake are still uncertain. OBJECTIVE: The objective of this study was to explore the sustainability trade-offs and synergies associated with a range of agroforestry systems in Europe and assess the underlying reasons for different performance regardin...
Article
Full-text available
Organic agriculture is widely accepted as a strategy to reduce the environmental impacts of food production and help achieve global climate and biodiversity targets. However, studies concluding that organic farming could satisfy global food demand have overlooked the key role that nitrogen plays in sustaining crop yields. Using a spatially explicit...
Article
Sustainability assessment is a complex field and its uptake amongst agricultural producers limited. Furthermore, the scope of current sustainability assessment tools does not extend to systems in which food production is integrated with production of non-food biomass (e.g. agroforestry). Participatory approaches to tool development offer a means to...
Article
Full-text available
Agroforestry systems have multifunctional roles in enhancing agronomic productivity, co-production of diversity of food and non-food products and provision of ecosystem services. The knowledge of the performance of agroforestry systems compared with monoculture is scarce and scattered. Hence, the objective of the study was to analyze the agronomic...

Full-text available
European sheep and goat farming faces diverse challenges at global or local scales and constitutes an important sector for many countries, playing important sociocultural, economic and environmental roles. A closer examination of the overall sustainability of the sector is necessary to assess the performance of different farm types in various geogr...
Article
Full-text available
Agriculture is a major contributor to global greenhouse gas (GHG) emissions and must feature in efforts to reduce emissions. Organic farming might contribute to this through decreased use of farm inputs and increased soil carbon sequestration, but it might also exacerbate emissions through greater food production elsewhere to make up for lower orga...
Article
Estimates of soil carbon changes, biodiversity and ecotoxicity have often been missing from life cycle assessment based studies of organic dairy products, despite evidence that the impacts of organic and conventional management may differ greatly within these areas. The aim of the present work was therefore to investigate the agnitude of including...
Article
Full-text available
Sustainable intensification is a process by which agricultural productivity is enhanced whilst also creating environmental and social benefits. We aimed to identify practices likely to deliver sustainable intensification, currently available for UK farms but not yet widely adopted. We compiled a list of 18 farm management practices with the greates...
Article
Full-text available
We assess the production impacts of a 100% conversion to organic agriculture in England and Wales using a large-scale linear programming model. The model includes a range of typical farm structures, scaled up across the available land area, with the objective of maximising food production. The effects of soil and rainfall, nitrogen (N) supply/offta...
Conference Paper
Full-text available
Assessing the sustainability of small ruminant systems is crucial to ensure their long-term viability, to identify potential areas of improvement, to uncover trade-offs between different aspects of performance and to, potentially, demonstrate benefits of particular management strategies. However, there is scarce literature and guidance regarding op...

The Public Goods Tool (PGT) assesses the agriculture related public goods” provided by a farm. The assessment was trialled on an initial pilot of seven agroforestry farms from five countries (UK, Italy, Poland, Romania, Denmark).
Article
Full-text available
Agroecological approaches to food production, including organic farming, rely on improved understanding of ecological principles and their application to the management of agroecosystems in order to reduce agrochemical use and improve the environmental impact of the production systems. Agroecological approaches place increased reliance on biologica...
Article
Full-text available
When trying to optimize the sustainability performance of farms and farming systems, a consideration of trade-offs and synergies between different themes and dimensions is required. The aim of this paper is to perform a systematic analysis of trade-offs and synergies across all dimensions and themes. To achieve this aim we used the Sustainability M...
Article
Full-text available
The dynamic model Nitrogen Dynamics in Crop rotations in Ecological Agriculture (NDICEA) was used to assess the nitrogen (N), phosphorus (P) and potassium (K) balance of long-term organic cropping trials and typical organic crop rotations on a range of soil types and rainfall zones in the UK. The measurements of soil N taken at each of the organic...
Article
Dairy farming is the largest agricultural contributor to greenhouse gas emissions in Europe. In this study, the carbon footprint of organic dairying was evaluated by means of a life cycle assessment, based on real farm data from six European countries: Austria, Belgium, Denmark, Finland, Italy and United Kingdom. A total of 34 farms were analysed....

Conference Paper
Full-text available
Of all anthropogenic greenhouse gas (GHG) emissions 18 % is estimated to originate in agriculture and the largest agricultural contributor to these emissions is the cattle farming (FAO 2006). According to Gerber et al. (2013) global cattle farming contributes an annual total of 4.6 Gt of CO 2 equivalents, dairy farmings' contribution to this being...
Article
Growing populations and a constrained fossil-manufactured energy supply present a major challenge for society and there is a real need to develop forms of agriculture that are less dependent on finite energy sources. It has been suggested that organic agriculture can provide a more energy efficient approach due to its focus on sustainable productio...
Article
Full-text available
Resource use and environmental impacts of a small-scale low-input organic vegetable supply system in the United Kingdom were assessed by emergy accounting and Life Cycle Assessment (LCA). The system consisted of a farm with high crop diversity and a related box-scheme distribution system. We compared empirical data from this case system with two mo...
Article
Purpose – The purpose of this paper is to consider whether UK consumers recognise and trust organic certification logos and whether the presence of these logos on a product increases consumer willingness to pay for that product. Design/methodology/approach – To ascertain the reaction of UK consumers to organic certification logos commonly used in...
Chapter
There has recently been an increase in interest in the “public goods” that could be provided by a farm alongside its primary function of agricultural production. This paper reviews recent reports on the topic of public goods and, in particular, the public goods provided by agriculture and then goes on to discuss the development of a tool which can...
Article
Full-text available
Climate change mitigation is urgent, and adaptation to climate change is crucial, particularly in agriculture, where food security is at stake. Agriculture, currently responsible for 20-30% of global greenhouse gas emissions (counting direct and indirect agricultural emissions), can however contribute to both climate change mitigation and adaptatio...

Full-text available
The introduction on the 1st July of the new mandatory EU logo for organic food and farming presents a new challenge for the various existing organic certification schemes in Europe. Details of the logo and its use can be found on http://ec.europa.eu/agriculture/organic/eu-policy/logo_en. A very helpful guidance note has been produced by OF&G and ca...

RELIVESTOCK will understand and mobilise the adoption of innovative practices, applied across-scales (animal, herd/farm, sector and region), to reduce the greenhouse gas emissions of livestock farming and increase climate change adptation capacity.
Project
REFOREST will use existing knowledge of temperate agroforestry systems to co-create solutions to key barriers that hinder wider adoption of AF by farmers in the EU and associated countries. The strategic objective is to enhance agroforestry and the sustainability of food production by internalising the value of carbon and biodiversity in farming business models.
