Zusammenfassung: In den Diskussionen über die Gemeinsame Agrarpolitik nach 2013 nimmt die Honorierung nicht marktgängiger gesellschaftlicher Leistungen der Landwirtschaft eine zentrale Rolle ein. Unterschiedliche Ansichten bestehen darüber, was unter diesen Leistungen genau zu verstehen ist und wie sie quantifiziert und monetarisiert werden können. Die hierzu durchgeführte Auswertung von rund 80 Studien zeigt einerseits, dass in der Bevölkerung eine generelle Zahlungsbereitschaft für solche Leistungen besteht, und andererseits, dass die ausgewerteten Fallstudien nicht auf Deutschland hochgerechnet werden können. Die Leistung „Offenhaltung der Landschaft“ verursacht - wenn sie nicht als Koppelprodukt unentgeltlich anfällt - Kosten, deren Höhe in starkem...

Rainfall or Price Variability: What Determines Rangeland Management Decisions? A Simulation-Optimization Approach to South African Savannas

Börner, Jan; Higgins, Steven Ian; Kantelhardt, Jochen; Scheiter, Simon.

Savannas cover the greater part of Africa and Australia and almost half of South America and contribute to the livelihoods of more than 350 million people. With the intensification of land use during the second half of the 20th century, savannas have become increasingly degraded through bush encroachment as a consequence of increased grazing pressure. Research on rangeland dynamics, however, provides contradicting answers with regard to the causes and possible remedies of bush encroachment. In this paper we present results from an application of a simulation-optimization model to the case of extensive rangeland management in South Africa. Our model differs from previous approaches in that it explicitly accounts for the influence of stochastic prices and...

Ecosystem Services Beyond Valuation, Regulation and Philanthropy: Integrating Consumer Values into the Economy

Tisdell, Clement A..

Analyzes the economics of alternative allocations of forested land for uses (dominant-use vs. multiple use) to ensure the survival of a viable population of a forest-dependent species, e.g. the orangutan. The alternatives are (1) setting aside a sufficient fully protected portion of the forest and allowing the rest to be used for intensive logging and (2) fully protecting none of the forested area but allowing a sufficient portion of it to be lightly (selectively) logged to ensure the survival of the population of the focal species with the remaining land (if any) being available for intensive use.

Can Dispersed Biomass Processing Protect the Environment and Cover the Bottom Line for Biofuel?

Egbendewe-Mondzozo, Aklesso; Swinton, Scott M.; Bals, Bryan D.; Dale, Bruce E..

This paper compares environmental and profitability outcomes for a centralized biorefinery for cellulosic ethanol that does all processing versus a biorefinery linked to a decentralized array of local depots that pretreat biomass into concentrated briquettes. The analysis uses a spatial bioeconomic model that maximizes predicted profit from crop and energy products, subject to the requirement that the biorefinery must be operated at full capacity. The model draws upon biophysical crop input-output coefficients simulated with the EPIC model, as well as input and output prices, spatial transportation costs, ethanol yields from biomass, and biorefinery capital and operational costs. The model was applied to 82 cropping systems simulated across 37...

In recent times, there has been increasing demand in the Canterbury region of New Zealand for the abstraction of water from rivers. The impact of this demand has lead to unacceptable minimum river flows and has adversely affected river ecology. In an effort to resolve these issues dams have been constructed. To evaluate the impact of these dam projects on all river values, an ecosystem services approach is developed. This ecosystem services approach coupled with various evaluation methods are applied for the purposes of assessing the cost-effectiveness of the Opuha Dam and the sustainability of the Opihi river system now modified by the Opuha Dam. To evaluate the cost-effectiveness of this dam project cost utility analysis is applied through the...

Economic Impacts of Yellow Starthistle on California Ranchers

Longhitano, Davide.

The main objective of this communication is to review the theoretical ecosystem and agroecosystem services assessment’s methods and to propose a thermoeconomic approach. The logic of thermoeconomic approach consists in analysing the use of natural resources during the production process, interpreting it as a thermodynamic conversion in order to assess the overall specific energy consumption of the systemic components arriving at estimates of fluxes and energy costs. This study analyses comparatively the main thermoeconomic-based approaches to verify the feasibility of the "energy value" as an appraisal criterion of agroecosystem services. In particularly among the reviewed approaches the Emergy synthesis seems the most appropriate tool to be empirically...

While the significant ecosystem damage caused by invasive weeds has been well documented, the economic impacts of specific invasive weed species are poorly understood. Yellow starthistle (Centaurea solstitialis L., hereafter YST) is the most widespread non-crop weed in California, resulting in serious damage to forage on natural range and improved pasture. A survey was administered to California cattle ranchers to investigate YST infestation rates, loss of forage quantity and value, and control or eradication efforts. The results were used to estimate county-wide economic losses for three focus counties, as well as state-wide economic losses, due to YST in California. Total losses of livestock forage value due to YST on private land for the state of...

Sauer, Johannes; Wossink, Ada.

We provide a new approach for assessing the cost of marginal ecosystem changes and the effectiveness of agri-environmental schemes. The approach is based on a theoretical and empirical analysis of the bio-economic production interactions between marketed outputs and non-marketed ecosystem services at the micro level. To frame the economic nature of the problem, we employ a generalized joint production model in combination with cost minimization. The generalized joint production framework allows for the consideration of complementary, substitutive and competitive relationships between agricultural production and non-marketed ecosystem services generation and avoids double counting. From this theoretical model we distinguish three theoretical cases depending...

The main objective of the paper is to study the importance of regional preferences in financing agri-environmental programs. The analysis is based on results of a case study conducted in South-eastern Poland. As environmental protection in agriculture is complex and often considered in political strategies, it is worth analyzing the differences in perception of the respective environmental objectives from a regional perspective. Taking into account natural conditions and the economic situation in agriculture in the voivodship Podkarpackie, the question is, how regional objectives could be achieved effectively with a given budget. Using linear programming, we discuss in this paper, how regional preferences would guide budget allocation.

Rural development in the European Union has to face several challenges. Negative effects of old and new challenges (if these challenges are not faced effectively) might enhance and accelerate those processes that are taking place slowly for the present but that are definitely irreversible. On the basis of sector-specific approach problems related to agriculture should be focused on. It has to be, however, highlighted that there is an ongoing paradigm change: there is a shift from the agricultural policy aiming at food self sufficiency and income parity towards a sustainable rural policy with spatial focus. The shift itself is considered a continuous challenge, too. The following questions as objectives of the paper arise: - Are there policy instruments...

This study aims to estimate the recreational use values of Great Lakes beaches using a two-level nested logit Random Utility Model. The choice set contains all 594 public Great Lakes beaches in Michigan. Beach sites located in the same Great Lakes water body are arranged into a nest. The trip data were obtained from a 2006 online survey using a web-panel of Michigan adults accessed through Survey Sampling International (SSI). The variables that affect the amount of utility derived from a particular site are the travel cost and site quality variables, which include beach length, days of beach advisory, and days of beach closure in 2006. We report the economic loss of permanently losing an individual beach site or a group of beach sites as well as benefits...

The main objective of the paper is to investigate effective financing scenarios for agri-environmental measures with regard to the environmental benefit, considering regional policy priorities. By means of the Analytic Hierarchy Process (AHP) and a Linear Programming (LP) approach we conduct multicriteria analysis and investigate conflicts between environmental objectives as well as their influence on financing scenarios for agri-environmental measures. The analysis is based on an explorative case study conducted in Poland in the Subcarpathia region and on interviews with agricultural experts. The results show that the budget allocation for agri-environmental measures is considerably dependent on preferences given to environmental objectives within...

This paper reports on and interprets the results of a survey of visitors to the Jourama Falls Section of the Paluma Range National Park located in Northern Queensland. It reports, amongst other things, on how much knowledge visitors to the site had about it before their visit, the procedures they adopted in deciding to visit it and how generally they go about deciding to visit tourist sites when on holidays. The results are consistent with those predicted by theories of bounded rationality and behavioural economics. Information is also provided on the value visitors placed on attractions at the Jourama Falls sites, their attitudes to the private supply of tourist/visitor services and facilities in national parks, the importance of wildlife as an attraction...

This study was conducted with the main objective of determining the linkages between poverty and land management practices in Uganda. The study used the 2002/03 Uganda National Household Survey (UNHS) and more focused data collected from a sub-sample of 851 households of the 2002/03 UNHS sample households. We found that farmers in Uganda deplete about 1.2 percent of the nutrient stock stored in the topsoil per year, which leads to a predicted 0.31 percent reduction in crop productivity. The value of replacing the depleted nutrients using the cheapest inorganic fertilizers is equivalent to about 20 percent of household income obtained from agricultural production. Econometric analysis of the survey results provides evidence of linkages between poverty and...

Incentive-based programs to reduce deforestation are expected to play an increasingly important role in global efforts to protect ecosystems and sequester carbon but their environmental effectiveness is not clear. We investigate program effectiveness and slippage in the context of Mexico's national payments for hydrological services program, which pays private and communal landowners to maintain forest cover on enrolled lands. To measure program impacts, we use matched controls drawn from the program applicant pool to establish counterfactual deforestation rates in the absence of payments. We find statistically significant but small to moderate avoided deforestation impacts. To examine slippage of deforestation to nonenrolled lands, we develop a model of...

Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

Herein we model the widespread dispersal and management of an invasive species as a weak-link public good. The risk of introduction is driven in part by economic activity, is influenced by policies directed at the risk, and economic activity responds/adapts to the risk. Framed around recent introductions and rapid spread of dreissenid mussels in the Western United States, we find three key results. First, partial equilibrium estimates of welfare loss are significantly overestimated relative to general equilibrium estimates. If ecosystem services and market goods are substitutes the partial equilibrium bias is greater than if they are compliments. Second, well-intended policies do not necessarily reduce overall risk; risk reduction actions can transfer risk...

Corruption in the forest sector of Swat, Pakistan is impairing the sustainable management of forest. We analyze corruption in a case study setting against the backdrop of the reform options that are most often cited as possible solutions. As we highlight in this study, the crime and punishment approach is not feasibly implemented if the overall institutional environment is weak. Since countrywide overhaul of corruption through sweeping reform programs, the other reform approach, is a difficult and lengthy task, there is a need for an alternative kind of reform. In the case of a corruption-ridden centralised forest management regime, institutional reform should move away from enforcement of existing institutions and promote communal management of natural...
