The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of the Watershead Restoration and Erosion Control Projects of the Aljibe Basin (Almería) Spain, presented here. The results obtained show that, in this case study, application of Contingent Valuation ascribes greater social profitability of the project, with 5.23 % of IRR (Internal Rate of Return), compared to the value obtained using classic methodology of 2.25%, thus enabling us to draw closer to the true socio-environmental value of this type of project. In any case, both possibilities rather than alternatives can be considered as complementary, by focusing on the valuation from different perspectives.

The Common Agricultural Policy (CAP) intervenes in most agricultural systems that provide positive environmental externalities using both direct payments and agrienvironmental schemes. In this context, the objective of this paper is to compare the efficiency of the current intervention system versus intervening using agri-environmental payments as a sole instrument. The cereal steppes agroecosystem of Tierra de Campos (Valladolid, Spain) has been selected to develop this comparison. A farm survey and a Positive Mathematical Programming Model have been combined to provide results of both alternative instruments. The farm survey was used to ask the farmers their payments demands to participate in the alternative instrument, supplying also qualitative information about how it is perceived by farmers. The payments demanded were simulated in the model to get environmental and economic indicators for both instruments. Instruments were evaluated using a cost-effectiveness approach were total public expenditure was conserved constant for both. The main conclusion of this research is that policy intervention effectiveness could be potentially increased using an agri-environmental scheme as the unique intervention instrument. Considering this finding, results transferability to other agricultural systems and policy consequences in the context of the CAP are finally discussed.

Participatory approaches in natural resource management are increasingly being criticized for their tendency to neglect power relations and conflicts of interests. Negotiation approaches have been proposed as a strategy to overcome such shortcomings. The increasing practical relevance of negotiation in natural resource management requires the development of theoretical concepts for analyzing the nature and outcome of such negotiation processes. Using the case of negotiations concerning crop-livestock conflicts in Sri Lanka as an empirical example, this paper applies the concept of political capital in combination with game theoretical modeling for an analysis of negotiation processes in natural resource management. An extended form game is used to examine the incentive structure of the resource users and the political decision-makers involved in the negotiation process. The pay-off of the resource users is measured in economic terms, while the pay-off of the political decision-makers is expressed in terms of political capital. The modeling exercise shows how the incentives of the resource users and the politicians depend on the probability that the public administration enforces a negotiated outcome. The paper discusses potential extensions of the model and concludes that the concept of political capital, in combination with game theoretical modeling, provides a useful tool for the analysis of negotiation approaches in natural resource management.

Water availability in semiarid regions commonly exhibits patterns of extreme variability. Even in basins with large infrastructure development, some users are subject to low levels of water reliability, incurring economic losses during periods of scarcity. More flexible instruments, such as voluntary exchanges of water among users, may help users reduce their risk exposure. Recent changes in the Spanish water Law have given an initial impulse to allow for lease-out contracts of water use rights. This paper analyses, from theoretical and empirical standpoints, the effect that establishing water markets has on the economic risk caused by water availability variations.

The empirical study is performed on an irrigation district of the Guadalquivir Valley (Spain) with fair levels of average water availability but a high probability of periods of extreme scarcity. A non-linear programming model is used to simulate irrigators’ behaviour and derive water demand functions. Another spatial equilibrium model is used to compute market exchange and equilibrium. These programming models are combined with statistical simulation techniques. It is shown that the probability distribution of profits for a representative irrigator is modified if water exchanges are authorised, resulting in unambiguous risk reductions. Results also suggests that if the market would be extended to several irrigation districts and users, each characterised by different hydrological risk exposure, the occurrence of extremely low benefits events would become more unlikely. In sum, it is shown that exchanging water in annual spot markets allows for the reduction of farmers’ economic vulnerability caused by the variability of water supply across irrigation seasons.

The United States is the leading country in the application of biotechnology to agricultural methods. One of the principal reasons for this is the flexibility of its legislation on Genetically Modified Organisms (GMO). A significant part of its production of soya or corn is already genetically modified, so that its companies need to avoid technical barriers to their exports in the world markets?. In the EU, negative public opinion has contributed to the adoption by the authorities of exigent legislation in order to avoid the possible risks to human health and the environment posed by GMO. The EU’s authorisation procedure for these organisms is long and meticulous.

Furthermore, a compulsory labelling system has been adopted for products, which contain GMO or genetically modified materials (GM materials). In 1998, American interests started to be adversely affected by European legislation. The USA Administration threatened to sue the EU before the World Trade Organisation (WTO). These threats have yet to be followed up with any action. The rules of international trade are regulated by agreements signed up to by the members of the WTO. The EU can argue that its authorisation procedure is designed to reduce the risks to health and the environment. This line of argument is compatible with the Agreements on Sanitary and Phytosanitary Measures (SPS) and Technical Barriers to Trade (TBT). The compulsory labelling system is also compatible with the Agreement on TBT if the WTO accepts that a product in which GM material is detected is not similar to a conventional one. The Protocol of Biosafety further supports the EU position since it advocates a cautious approach exemplified by the fact that the Protocol permits consideration of non-scientific risks during risk assessment. However, the Protocol is not yet in force, it is pending ratification by at least 50 countries and, now more than ever, it is uncertain whether the United States will be willing to ratify the Protocol. However, we cannot be sure that there will be future commercial controversy, which will show the contradictions between the commercial agreement and the environmental one.

Relationships between the greenhouse effect and agricultural activity are usually and firstly considered in terms of the impact of climate change on agriculture. But in reverse, farmers and herders may react to a climate policy imposing a carbon price to GHG-emitting activities, and possibly contribute to the emissions mitigation as well as to carbon sequestration. The degree of efficiency of the reactions will vary across regions of the world and across activities. A methodology considering risk associated with technology changes is proposed for estimating and accounting these reactions under production and resource constraints. For a business-as-usual scenario quantified by the integrated assessment model Image, decisions concerning land-use and alternative practices are modeled. Results indicate that main agricultural activities provide little room for manoeuvre for emissions mitigation.

This paper examines the factors influencing farmers' participation in several agri-environmental schemes. A multinominal logit model is used to separate between participating and nonparticipating farmers. In addition this model allows to predict farmers participation in one measure as well as in different measures simultaneously. Data stems from a survey conducted in eight European countries and includes a description of both farmer and farm characteristics. Three categories of schemes have been analysed: landscape maintenance, biodiversity protection and restriction of intensive farming practices. The combination of these three types of schemes provides eight possible packages which can be selected by eligible farmers.

The multinominal logit model shows the importance of both farm and farmer as well as attitudinal characteristics on the participation in different combinations of schemes. For instance, the environmental concern favours landscape maintenance and biodiversity protection as well as their combinations with schemes requiring restrictions of intensive practices. However, it has a negative effect on the single participation in schemes requiring restrictions of intensive practices only. Our analysis confirms a number of previous findings. In addition, it shows the importance for policy makers to take into account that farmers have the opportunity to enter several schemes simultaneously. Indeed, due to cost complementarities, joint participation provides both private and public benefits.

The new Rural Development Regulation of the EU reflects the shift of attention within rural areas from agricultural production towards rural development and embraces both, farmers and non-farm residents. While agricultural production is required to comply with environmental standards, rural areas also have to fulfil the growing demand for landscape, outdoor recreation and wildlife conservation. This paper develops a model of a rural area where farmers and non-farm residents live together. A central government uses a combination of two-policy instruments - direct compensation payments and public services - aimed at encouraging farmers to adopt environmentally beneficial practices and at the same time to increase the provision of country-side amenities and the sustained vitality of the rural area. The optimal mix of the policy instruments is evaluated under various governmental objectives. The analysis suggests that a combination of direct payments to farmers with the supply of local public services is a promising tool for rural policy development initiatives in the EU.

This paper analyses the effect of environmental and quality improvement practices on the value added of the fruit and vegetable sector. These practices form part of the incentive-based programmes established by the Common Agricultural Policy. Taking the investment in quality-environmental activities as knowledge capital, we propose a specific analysis that evaluates the effect of the factors of the production function and of the current subsidies over the value added. In general, the share of qualityenvironmental activities in the rise of the product's market value is quite high. The analysis reflects that the expenditure on these activities is still higher than their benefit, and that the current subsidies can hardly be considered encouraging factors for the development of the above-mentioned practices.

Organic farming is increasingly considered in the European Common Agricultural Policy. Sound evaluations of the effects of policy measures on organic farms in the EU are needed to face the challenges in future policy design. The effects of various policy scenarios on profitability and development strategies of typical organic arable and dairy farms are analysed for the EU countries Germany, Denmark, the United Kingdom and Italy. Based on an approach which integrates simulation modelling and focus groups, profitability of model farms is analysed ex-post for year the 1999 and their potential development simulated until 2008 under Agenda 2000 and three alternative policy scenarios. For each policy scenario potential farm adaptation strategies are analysed.

Size, structure, productivity, achieved output prices and policy surrounding of typical organic farms differ widely between countries and farm types. Great differences in the contribution of payments to total farm profit and farm family labour remuneration are observed. Dairy model farms are expected to slightly benefit from Agenda 2000, while arable farms are more susceptible to price reductions realised in the Agenda 2000 package. In adaptation to Agenda 2000 organic dairy farms are expected to grow, while arable farms are more likely to diversify production or envisage valued adding strategies. The effects of alternative policy scenarios on profitability of typical farms are similar in all countries. The choice of adaptation strategy of farmers in the different countries, however, vary significantly, mainly due to the current market situation.

In this article, we investigate welfare economic aspects of multifunctional agriculture, putting emphasis on the provision of rural environmental benefits. The formal analysis shows that the efficiency prices of agricultural and forest land include important amenity and non-use values that exhibit the character of undepletable externalities. Thus, to achieve a socially optimal land allocation these externalities must be internalised. We propose the compensation to agricultural and forest managers according to the marginal external benefit of their land, and a charge-subsidy scheme to improve rural water quality. Altogether, this is consistent with the requirement of optimal land allocation and would not cause additional market distortions. Moreover, it would leave the property right on the land and landscape benefits with the farmers, and assign the right on clean air and water to the consumers.

A new method for analysing environmental efficiency, based on the materials balance, is proposed. With this method, an environmental allocative efficiency measure can be defined analogously to the more commonly used economic allocative efficiency. Nutrient surplus in pig fattening, a typical balance indicator, is used to illustrate the concept in a two input - one output case. The materials balance based efficiency analysis is elaborated using data envelopment analysis (DEA). Results are compared with those of more common, merely input or output oriented DEA approaches. A main conclusion is that, ignoring the balance feature of environmental issues such as nutrient surplus might be a main reason why traditional integral analyses of economic and environmental efficiency yield contradictory conclusions.
