IMPACTS OF POLICY REFORM ON SUSTAINABILITY OF HILL FARMING IN UK BY MEANS OF BIO-ECONOMIC MODELLING AgEcon
Acs, Szvetlana; Hanley, Nick; Dallimer, Martin; Robertson, Philip; Gaston, Kevin J.; Armsworth, Paul R..
Hill farming in UK is experiencing very difficult economic circumstances and many farmers rely on subsidies provided by the government for a large fraction of their income. The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes � in particular, the move from area- and headage-based payments to the Single Farm Payment, and how optimal business plans should respond to these changes. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms, in order to investigate how the land is managed on hill farms including ongoing policies and...

Eliciting public preferences for managing the public rights of way AgEcon
Morris, Joe; Colombo, Sergio; Angus, Andrew J.; Stacey, K.; Parsons, D.; Brawn, M.; Hanley, Nick.
Public Rights of Way (PROW) in England and Wales, provides a wide range of social and economic benefits to those other than owners of land. The protection and extension of PROW are an important way of encouraging people to engage in informal enjoyment of urban and rural areas, with beneficial consequences for health and welfare. In urban areas they provide networks of mobility and interaction for people at the community level, helping to reduce reliance on motorised transport. In the rural context they define access to the countryside, critically linked to recreation and tourism, as well as providing mobility networks for local residents. This study describes the use of a Choice Experiment (CE) to derive monetary estimates the social benefits of PROW in an...

The impacts of knowledge of the past on preferences for future landscape change AgEcon
Colombo, Sergio; Hanley, Nick; Ready, Richard C..
In this paper, we investigate whether people’s knowledge of the past influences their preferences and values towards future landscape change. “Knowledge of the past” is one aspect of the information set held by individuals, and a well-established finding in stated preference work is that changes in information can change preferences and values. The case studies used here relate to prospective changes in woodland cover in a UK national park the Lock Lomond and Trossachs. We find that people who are made aware that the landscape has changed over time are more likely to favour changes to the current landscape. Knowledge of the past therefore seems to have an impact on preferences for future landscapes.

What Determines Prediction Errors In “Benefits Transfer” Models? AgEcon
Colombo, Sergio; Hanley, Nick.
The aim of BT techniques is to provide decision makers with a monetary valuation of environmental goods and service in a cost-effective and timely manner, since original valuation studies are both expensive and time-consuming. Demands for environmental valuation estimates are rising in the policy community in both Europe and the US. In the UK, widespread use of benefits transfer has already occurred within policy making and regulatory bodies, for instance in the setting of water quality targets for private water companies and in the design of agrienvironmental policy. An important question is how big the errors are resulting from this practice, and how sensitive transfer errors are to how the benefits transfer is conducted. In this study we employ a choice...

Análisis de la metodología de los puntos de corte para la identificación de las respuestas “inconsistentes” en los modelos de elección discreta AgEcon
Colombo, Sergio; Hanley, Nick; Bush, Glenn.
En el método del experimento de elección se supone que el entrevistado es perfectamente racional, está informado y maximiza su utilidad siguiendo una regla de elección perfectamente compensatoria. Sin embargo, es posible que los individuos empleen otras reglas de decisión en sus elecciones para simplificar el esfuerzo cognitivo del ejercicio propuesto. En este trabajo se emplea la metodología de los valores de corte para incorporar en el experimento de elección reglas de decisión no compensatorias, y se amplia esta metodología para identificar respuestas inconsistentes. Los resultados indican que el empleo de los valores de corte mejora la capacidad descriptiva de los modelos de elección, y puede ser muy útil para la identificación de inconsistencias en la...

Transferring the Benefits of Water Quality Enhancements in Small Catchments AgEcon
Black, Andrew; Colombo, Sergio; Hanley, Nick; Tinch, Dugald; Aftab, Ashar; Bergmann, E. Ariel.
The Water Framework Directive (WFD) sets targets of "Good Ecological Status" for water bodies across the EU. Environmental regulatory authorities must undertake economic analysis of all water bodies as part of the process of drawing up catchment management plans. In this paper, we test the transferability of benefit estimates across the kinds of smaller catchments where original benefits estimation is unlikely to be undertaken on grounds of costs. This is done in a context where agricultural-source nonpoint pollution and irrigation water abstraction are the main threats to ecological status.

Linking biodiversity, land-use and incomes at the farm level: an interdisciplinary modelling approach AgEcon
Acs, Szvetlana; Dallimer, Martin; Hanley, Nick; Gaston, Kevin J.; Armsworth, Paul R..
Recent decades have witnessed substantial losses in biodiversity in Europe, partly driven by the ecological changes associated with intensification of agricultural production. These changes have particularly affected biodiversity in marginal areas, such as the uplands in UK, since habitat change has been greater than in lowland zones. Livestock farming is the main land use in these areas, and economic viability of farmers substantially relies on income coming from agricultural subsidies and agrienvironmental payments. The production decisions have an effect on biodiversity, although the precise links are subject of much debate. To assess the effects of policy changes on farm incomes and biodiversity, we developed ecological-economic models for three...

The Social-Environmental Impacts Of Renewable Energy Expansion In Scotland AgEcon
Bergmann, E. Ariel; Colombo, Sergio; Hanley, Nick.
Investments in renewable energy, such as new wind farms and hydro schemes, are being promoted as a new means of diversifying rural employment in Scotland*. However, such investments are associated with a range of environmental impacts which might be detrimental to other economic activities, such as those based on nature tourism. When designing policy instruments for more sustainable energy futures, therefore, the main goal is to generate the lowest possible adverse socio-economic and environmental impacts ensuring a certain degree of economic efficiency. We use a Choice Experiment to quantify peoples’ preferences over these multiple impacts of renewable energy in Scotland. We find that landscape, wildlife and air pollution impacts are all significant for...

IMPACTS OF POLICY REFORM ON HILL FARM INCOMES IN UK AgEcon
Acs, Szvetlana; Dallimer, Martin; Hanley, Nick; Armsworth, Paul R..

The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes – in particular, the move from area- and headage-based payments to the Single Farm Payment. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms. Based on these surveys six representative farm linear programming models was developed, which represent typical farm types in the uplands in the Peak District....

Effect of decoupling and agri-environmental policy on biodiversity in the uplands in UK AgEcon
Acs, Szvetlana; Dallimer, Martin; Hanley, Nick; Gaston, Kevin J.; Armsworth, Paul R..
Recent decades have witnessed substantial losses in biodiversity in Europe, principally driven by the ecological changes associated with intensification of agricultural production. These changes especially affected the biodiversity in the marginal areas, such as the uplands in UK, since the habitat change was greater than in lowland zones. Livestock farming is the main land use in these areas, and economic viability of these farmers substantially relies on income coming from agricultural subsidies and different agri-environmental payments. The production decisions are influenced by these incentives and those have a subsequent effect on biodiversity. In order to address the problem of economic viability of farmers together with its impact on biodiversity...

Análisis econométrico de la heterogeneidad de las preferencias de los individuos: aplicación a la valoración económica de la conservación del paisaje agrícola de montaña AgEcon
Colombo, Sergio; Hanley, Nick.
The need to account for respondents’ preference heterogeneity in stated choice models has motivated researchers to apply random parameter logit and latent class models. In this paper we compare these three alternative ways of incorporating preference heterogeneity in stated choice models and evaluate how the choice of model affects welfare estimates in a given empirical application. Finally, we discuss what criteria to follow to decide which approach is most appropriate. RESUMEN: La necesidad de incorporar la heterogeneidad en las preferencias de los individuos en los modelos de elección discreta ha llevado a los investigadores a emplear siempre más frecuentemente modelos de parámetros aleatorios o de clases latentes. En este artículo se comparan tres...
