A metafrontier approach to measuring technical efficiencies across the UK dairy sector 31
Barnes, Andrew Peter; Revoredo-Giha, Cesar; Sauer, Johannes.
A regional approach is applied to measure technical efficiencies on dairy farms which employs the deterministic metafrontier approach. We construct six super regions for the UK, i.e. Eastern, Western, Northern England, Wales, Scotland and Northern Ireland. Data are collected through three different administrative systems, all be it under the same FADN guidance. We find for dairy farming comparative indicators of performance in all three data sets. The stochastic frontier approach is applied to construct 6 regional frontiers and a pooled (UK) dataset for comparison. A likelihood ratio test rejects the null hypothesis that these regions operate under a common frontier which may indicate bias in previous attempts to measure dairying efficiency at the country...

A Structural Equation Model of Farmers Operating within Nitrate Vulnerable Zones (NVZ) in Scotland 31
Toma, Luiza; Barnes, Andrew Peter; Willock, J.; Hall, Clare.
Structural Equation Modelling (SEM) offers a theoretical basis for developing an understanding of the relationships between attitudes and behaviour. This paper imposes the SEM framework to a compulsory regulation which focuses on reducing diffuse water pollution, namely Nitrate Vulnerable Zones (NVZ). We use a data set collected through a farm survey within NVZs in Scotland in 2007. The model includes six latent variables expressing farmers’ nitrate reducing behaviour, nitrate reducing and profit maximizing behavioural propensities and the underlying determining factors, namely attitude (risk perception) and socio-economic latent variables (access to information and stocking density). The results indicate that the model has an adequate fit to the data and...

MARGINAL ABATEMENT COST CURVES FOR UK AGRICULTURAL GREENHOUSE GAS EMISSIONS 31
Moran, Dominic; MacLeod, Michael J.; Wall, Eileen; Eory, Vera; McVittie, Alistair; Barnes, Andrew Peter; Rees, Robert; Topp, Cairistiona; Moxey, Andrew.
This paper addresses the challenge of developing a ‘bottom-up’ marginal abatement cost curve (MACC) for greenhouse gas emissions from UK agriculture. A MACC illustrates the costs of specific crop, soil, and livestock abatement measures against a ‘‘business as usual’’ scenario. The results indicate that in 2022 under a specific policy scenario, around 5.38 MtCO2 equivalent (e) could be abated at negative or zero cost. A further 17% of agricultural GHG emissions (7.85 MtCO2e) could be abated at a lower unit cost than the UK Government’s 2022 shadow price of carbon (£34 (tCO2e)-1). The paper discusses a range of methodological hurdles that complicate cost-effectiveness appraisal of abatement in agriculture relative to other sectors.

Measuring the Sustainability of the UK Food Chain 31
Barnes, Andrew Peter; McVittie, Alistair.
Recent policy interest has been directed at the sustainability of food industries, in particular the post-farm gate food chain. This comprises of manufacturing, wholesaling, retailing and catering. In order to measure sustainability Byerlee and Murgai (2001) have argued that productivity measures, alongside key indicators of resource quality trends, should be used to indicate sustainable growth. This paper adopts this approach by presenting Fisher indexes of both Total Factor Productivity (TFP) index and for prominent externalities emerging from the food chain over the period 1998 to 2002. TFP shows an average annual growth rate of –0.52% per annum. Input growth, in particular intermediate purchases, has outstripped output growth over the entirety of this...

A Total Factor Productivity Index for Scottish Agriculture 1973-2004 31
Barnes, Andrew Peter.
Thirtle et al (2003) have provided a Total Factor Productivity (TFP) index for UK agriculture. This note follows a similar methodology to construct a TFP index for Scottish agriculture beginning in 1973 and ending in 2004. Essentially, Scottish agricultural growth grew strongly during the 1970s but then fell to negative levels over the period 1984-2004. In comparison to the UK Index, Scotland has performed poorly and is only showing signs of a positive recovery from 2000 onwards.

Technical Efficiency Estimates of Scottish Agriculture: Evidence from the dairy, sheep and cereals sector 31
Barnes, Andrew Peter.
Technical efficiency, the ratio of physical inputs to outputs, is a popular means of assessing agricultural performance. Benchmarking of these efficiencies is a fundamental tool for the farming industry. More sophisticated techniques have been developed recently which offer a greater degree of complexity for measuring technical efficiency. This paper adopts a parametric approach, referred to as stochastic production frontiers (SPF), to study three major sectors the Scottish agricultural economy, namely i) cereals, ii) dairy, and iii) sheep, over the period 1989 to 2004.

Policy Implications of a Behavioural Economics Analysis of Land Use Determinants in Rural Scotland 31
Toma, Luiza; Sutherland, Lee-Ann; Barnes, Andrew Peter; Renwick, Alan W.; McCrum, Gillian; Blackstock, Kirsty.
The paper analyses the land use behaviour of Scottish land managers and the factors influencing it in the current context of the EU rural land use policies. The analysis employs a frequently used behavioural economics method, namely structural equation modelling (SEM). Central to the empirical analysis in this paper is a cross-section database containing data collected in May to June 2009 through telephone interviews of 600 land managers in Scotland. The model tests and estimates the relationships between land use behaviour, i.e., behavioural intentions to change the size of business/holding, and several of its a priori determinants found significant in the scientific literature. The results indicate that a stronger propensity to change size of their...

Farmer Responses to Nitrate Vulnerable Zone Designation in Scotland 31
Barnes, Andrew Peter; Willock, J.; Hall, Clare; Luiza, Toma.
Nitrate Vulnerable Zones (NVZ) were introduced in response to the Nitrates Directive (91/676/EEC) which states that all EU countries must reduce the nitrate in drinking water to a maximum of 50mg/l. Farmers within a designated NVZ must adhere to strict rules over the timing and application of nitrogen from organic and inorganic sources. In Scotland, four NVZ regions were designated in 2003, covering around 14% of the land area. This paper outlines the results of a recent study to understand farmer activities in response to and attitudes towards NVZ regulations. A telephone survey of 177 farmers was administered, supplemented by four workshops held in each NVZ region. This was to explore, both quantitatively and qualitatively, farmer behaviour and attitudes...

An analysis of milk quota abolition impact on Scottish farmers’ behaviour 31
Toma, Luiza; Barnes, Andrew Peter; Renwick, Alan W..
This paper analyses factors influencing Scottish dairy farmers’ intentions to change size of business in response to milk quota abolition. The analysis uses structural equation modelling and is based on survey data collected in 2009 through telephone interviews with 533 farmers. Results suggest that farmers who (1) intend to leave their farm to children; (2) have not inherited their farm from previous generation; (3) perceive a lower impact of milk quota abolition on business; (4) have less negative attitudes towards policies/regulations; and (5) perceived a lower influence of policies/markets on business during the past decade are most likely to increase farm size.

A Metafrontier Analysis of Technical Efficiency of Selected European Agricultures 31
Barnes, Andrew Peter; Revoredo-Giha, Cesar.
Technical efficiency refers to the situation where it is impossible for a firm to produce, with the given know-how, (1) a larger output from the same inputs or (2) the same output with less of one or more inputs without increasing the amount of other inputs. In practice, the interest is on the relative position in terms of efficiency of a particular firm with respect to others. Therefore, technical efficiency is characterised by the relationship between observed production and some ideal or potential production (Greene, 1993). Although the beginning of the efficiency work can be traced to the 1950s (Farrell, 1957), there have been a growing interest on its use in benchmarking performance, predominantly as a means of identifying best practice and improving...

A Total Social Factor Productivity Index for the UK Food Chain Post-Farm Gate 31
Barnes, Andrew Peter; McVittie, Alistair.
The UK post-farm gate food chain comprises manufacturing, wholesaling , retailing and catering. Current turnover is around £250 billion per annum. Total factor productivity measures the ratio of inputs to outputs. However, most studies have only included the marketable inputs and outputs within the system. Following criticisms of the negative effects of the food chain this paper adopts a n index based approach to measuring Total Social Factor Productivity, which includes the major externalities within the food chain. Generally, whilst TFP growth rates are low over the period 1998-2002, these have reduced even further when negative externalities are included.

Marginal abatement cost curves for UK agriculture, forestry, land-use and land-use change sector out to 2022 31
Moran, Dominic; MacLeod, Michael J.; Wall, Eileen; Eory, Vera; McVittie, Alistair; Barnes, Andrew Peter; Rees, Bob; Smith, Peter; Moxey, Andrew.
Greenhouse gas emissions from agriculture, land use, land use change and forestry (ALULUCF) are a significant percentage of UK industrial emissions. The UK Government is committed to ambitious targets for reducing emissions and all significant industrial sources are coming under increasing scrutiny. The task of allocating shares of future reductions falls to the newly appointed Committee on Climate Change (CCC), which needs to consider efficient mitigation potential across a range of sectors. Marginal abatement cost curves are derived for a range of mitigation measures in the agriculture and forestry sectors over a range of adoption scenarios and for the years 2012, 2017 and 2022. The results indicate that in 2022 around 6.36 MtCO2e could be abated at...
