The purpose of this note is to set out the underlying philosophy of the ecosystem services approach as it is applied in UK policy circles. The aim is to clarify some flexible "ground rules" which should guide both the use of this type of decision support tool itself, and the interpretation of...

Ricardian models predicting the impact of climate change on agriculture are typically estimated on data aggregated across counties and assuming additively separable effects of temperature and precipitation. We investigate the potential bias induced by such assumptions by using a large panel of...

Arguably the greatest challenge to contemporary research is to capture the inter-relatedness and complexity of the real world environment within models so at to better inform decision makers of the accurate and complete consequences of differing options. The paper presents an integrated model of...

In this paper we present a novel methodology to determine the annual value of recreational visit flows to different habitat types in Great Britain. We combine different empirical models to predict the spatial distributions of recreational value across Great Britain. The models use a combination...

The opportunity Value of Travel Time (VTT) is one of the most important parts of the total cost of recreation day-trips and arguably the most difficult to estimate. Most studies build upon the theoretical framework proposed by Becker's (1965) by using a combination of revealed and stated...
