We are interested in three related questions: (1) How should accounting prices be estimated? (2) How should we evaluate policy change in an imperfect economy? (3) How can we check whether intergenerational well-being will be sustained along a projected economic programme? We do not presume that...

This paper considers the relationship between natural resource management and poverty by analysing a specific example: an inland fishery in Bangladesh. The analysis involves substantial extensions to standard models and allows the simulation of market distortions and alternative management...

When economic agents decide their optimal environmental behavior, they have to take into account non continuos evolutionary trends and irreversible changes characterising environmental phenomena. Given the still non perfect biophysical and economic knowledge, decisions have to be taken in an...

The purpose of the present paper is to describe the role of uncertainty and technical change in an environmental context. Which impact does ecological uncertainty have on physical and R&D investments' decisions? How are pollution trajectories modified when uncertainty is taken into account? To...

The intrinsic complexity of the sustainability concept challenges research towards more sophisticated ways to model and assess the dimensions underlying it. However, currently adopted modelling techniques and indicators frameworks are not able to give an integrated assessment through the...

The Nostrum-DSS EU funded Co-ordination Action (CA) aims at contributing to the achievement of improved governance and planning in the field of sustainable water management within the Mediterranean Basin by establishing a network between the science, policy, and civil society spheres and through...

Funding adaptation requires adequate governance and there are different ways to organise and channel the funds to where it is most efficient and most necessary. This paper investigates this issue and studies the practical implementation of a development under conditionality, namely...

Farmland values have traditionally been valued using seasonal temperature and precipitation. A new strand of the literature uses degree days over the growing season to predict farmland value. We find that degree days and daily temperature are interchangeable over the growing season. However, the...

Agricultural biodiversity is a crucial environmental resource. Much of the agricultural biodiversity remaining today is found on the semi-subsistence farms of poorer countries and on the small-scale farms and home gardens of more industrialised nations. The traditional Hungarian home gardens,...

Many nonmarket valuation models, such as the Ricardian model, have been estimated using cross sectional methods with a single year of data. Although multiple years of data should increase the robustness of such methods, repeated cross sections suggest the results are not stable. We argue that...
