Modelling the value of a multifunctional landscape – A discrete choice experiment AgEcon
Borresch, Rene; Maas, Sarah; Schmitz, Kim; Schmitz, P. Michael.
In the context of today’s intensive discussion of landscape multifunctionality, one primary objective of the current European Union policy is to support the implementation of multifunctionaly within the EU. In order to assess the economical feasibility of the implementation of a multifunctional land use in the Wetterau region in Germany this study addresses the question whether the local population, which is above all affected by the degradation of landscapes, benefits from a change from today’s landscape dominated by intensive agricultural production towards a multifunctional landscape. Based on data obtained by discrete choice experiments in the Wetterau region, a cost-benefit-analysis is carried out using the modelling and assessment framework CHOICE....

Measuring Eco-efficiency of Agricultural Activity in European Countries: A Malmquist Index Analysis AgEcon
Serrao, Amilcar.
This paper develops an environmental performance index by applying the benefit of the doubt weighting and the Malmquist index concepts using Kuosmanen and Kortelainen’s approaches. The main difference between these approaches and other methods is that environmental performance is based on the definition of the eco-efficiency as the ratio of economic value added to the environmental damage index. The overall environmental performance index is also decomposed into two components representing changes due to technological progress (or regress) and due to changes in relative eco-efficiency. The dynamic environmental performance analysis is applied to 15 European agricultures from 1990 to 2004. Model results show that technical progress mostly explain...

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

Valuation Methods for Environmental Benefits in Forestry and Watershed Investment Projects AgEcon
Cavatassi, Romina.
The understatement or omission of the environmental costs and benefits associated with forest management options results in project evaluations and policy prescriptions that are less than socially optimal. The aim of this paper is to examine the full range of costs and benefits associated with forests, distinguishing between how these should, and actually are, included in economic analyses. The paper first describes the economic analysis undertaken in the project evaluation procedure of the World Bank. The second section deals with all costs and benefits that typically occur in forestry projects. Costs and benefits are classified as on-site private, on-site public or global according to their nature and area of impact and according to the Total Economic...

Abatement and Transaction Costs of Carbon-Sink Projects Involving Smallholders AgEcon
Cacho, Oscar J.; Lipper, Leslie.
Agroforestry projects have the potential to help mitigate global warming by acting as sinks for greenhouse gasses. However, participation in carbon-sink projects may be constrained by high costs. This problem may be particularly severe for projects involving smallholders in developing countries. Of particular concern are the transaction costs incurred in developing projects, measuring, certifying and selling the carbon-sequestration services generated by such projects. This paper addresses these issues by analysing the implications of transaction and abatement costs in carbon-sequestration projects. A model of project participation is developed, which accounts for the conditions under which both buyers and sellers would be willing to engage in a carbon...

The impact of changing agricultural policies on jointly used rough pastures in the Bavarian Pre-Alps - an economic and ecological scenario approach AgEcon
Roeder, Norbert; Lederbogen, Dirk; Trautner, Juergen; Bergamini, Ariel; Stofer, Silvia; Scheidegger, Christoph.
The following paper assesses the impact of different policy options on the land use and associated biodiversity values of jointly organized low intensity grazing systems (‘Allmende’) in Southern Bavaria. We use an integrated economic and ecological modelling approach to compare the results of the scenarios with a reference situation that reflects the Common Agricultural Policy prior to the Fischler Reform. The economic sub model is based on single farms which alter their land use in response to economic stimuli. Within the economic part, key factors like the farm’s endowment with machinery, quota and buildings but also the farmer’s attitude are regarded. Within the rule based ecological sub model we analyze three main parameters: (a) protected habitats...

What Are Ecosystem Services? The Need for Standardized Environmental Accounting Units AgEcon
Boyd, James; Banzhaf, H. Spencer.
This paper advocates consistently defined units of account to measure the contributions of nature to human welfare. We argue that such units have to date not been defined by environmental accounting advocates and that the term "ecosystem services" is too ad hoc to be of practical use in welfare accounting. We propose a definition, rooted in economic principles, of ecosystem service units. A goal of these units is comparability with the definition of conventional goods and services found in GDP and the other national accounts. We illustrate our definition of ecological units of account with concrete examples. We also argue that these same units of account provide an architecture for environmental performance measurement by governments, conservancies, and...

Effects of Great Barrier Reef Degradation on Recreational Demand: A Contingent Behaviour Approach AgEcon
Kragt, Marit Ellen; Roebeling, Peter C.; Ruijs, Arjan.
Agricultural run-off from the Great Barrier Reef catchment area may cause degradation of coral reefs, affecting the tourism sector that relies on healthy reefs for its income generation. A Contingent Behaviour approach is used to determine the effect of reef degradation on demand for recreational dive and snorkel trips, for a case study of the Great Barrier Reef (GBR) in Australia. We assessed how reef degradation affects GBR tourism and to what extent reef-trip demand depends on the visitors' socio-economic characteristics. A count data model is developed, and results indicate that an average visitor would undertake about 60% less trips to the GBR per year, given a combined 80%, 30% and 70% decrease in coral cover, coral diversity and fish diversity,...

The economic assessment of changes in ecosystem services: and application of the CGE methodology AgEcon
Bosello, Francesco; Eboli, Fabio; Parrado, Ramiro; Nunes, Paulo A.L.D.; Ding, Helen; Rosa, Renato.
The present study integrates Computable General Equilibrium (CGE) modelling with biodiversity services, proposing a possible methodology for assessing climate-change impacts on ecosystems. The assessment focuses on climate change impacts on carbon sequestration services provided by European forest, cropland and grassland ecosystems and on provisioning services, but provided by forest and cropland ecosystems only. To do this via a CGE model it is necessary to identify first the role that these ecosystem services play in marketable transactions; then how climate change can impact these services; and finally how the economic system reacts to those changes by adjusting demand and supply across sectors, domestically and internationally

CAN DOMESTICATION OF WILDLIFE LEAD TO CONSERVATION? THE ECONOMICS OF TIGER FARMING IN CHINA AgEcon
Abbott, Brant; van Kooten, G. Cornelis.
Tigers are a threatened species that might soon disappear in the wild. Not only are tigers threatened by deteriorating and declining habitat, but poachers continue to kill tigers for traditional medicine, decoration pieces and so on. Although international trade in tiger products has been banned since 1987 and domestic trade within China since 1993, tigers continue to be poached and Chinese entrepreneurs have established tiger farms in anticipation of their demise. While China desires to permit sale of tiger products from captive-bred tigers, this is opposed on the grounds that it likely encourages illegal killing. Instead, wildlife conservationists lobby for more spending on anti-poaching and trade-ban enforcement. In this study, a mathematical...

Optimal Management of a Potential Invader: The Case of Zebra Mussels in Florida AgEcon
Lee, Donna J.; Adams, Damian C.; Rossi, Frederick J..
Dominant users of Lake Okeechobee water resources are agricultural producers and recreational anglers. These uses will be directly affected, should the lake become infested with zebra mussels. We employ a probabilistic bioeconomic simulation model to estimate the potential impact of zebra mussels on consumptive water uses, recreational angling, and wetland ecosystem services under alternative public management scenarios. Without public management, the expected net economic impact from zebra mussels is - $244.1 million over 20 years. Public investment in prevention and eradication will yield a net expected gain of +$188.7 million, a superior strategy to either prevention or eradication alone.

Assessing the impact of rural policy on biodiversity: High Nature Value Farming in Italy AgEcon
Trisorio, Antonella; Borlizzi, Andrea.
Farming practices and the conservation value of farmland are intimately interconnected. The recent policy debate has shed light on the need to address farming activities towards a more sustainable path, and has advocated for a reallocation of payments towards farming systems that provide public goods. This paper aims to explore likely HNV farms policy needs through the use of HNV farming system indicators.

Educational Function of Agriculture and Farm Diversification: Evidence from Dairy Farming Experience Services in Japan AgEcon
Ohe, Yasuo.
To promote multifunctional activity, it is crucial to clarify how jointness is formed in connection with farm structure. This paper examines the relationship between multifunctional activity and farm structure by focusing on the educational function of dairy farming, i.e., farming experience services, in Japan. The main findings were as follows. First, from our conceptual consideration we can say that the educational function is determined by technical and institutional jointness and there is a U-shaped relationship between farm diversification and provision of farming experience services. In addition, the national program aimed at promoting this educational function was effective in enhancing this function. Second, however, from the empirical evaluation...

Quantifizierung „gesellschaftlich gewünschter, nicht marktgängiger Leistungen“ der Landwirtschaft AgEcon
Plankl, Reiner; Weingarten, Peter; Nieberg, Hiltrud; Zimmer, Yelto; Isermeyer, Folkhard; Krug, Janina; Haxsen, Gerhard.
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...

The Survival of a Forest-dependent Species and the Economics of Intensity of Logging: A Note AgEcon
Tisdell, Clement A..
Analyses the economics of alternative land-use allocations for a forested area that ensure a targeted viable population of a forest-dependent species, such as the orangutan. The alternative of setting aside a sufficient fully protected portion of the forested area allowing the rest to be used for intensive forestry (or another intensive land use) in which the focal species is unable to survive is compared with that of fully protecting none of the forested area but allowing a sufficient portion of it to be lightly logged to ensure the survival of the targeted population of the focal species with the remainder of the land area (if any) being available for intensive use. The conditions for determining the least cost option (the one that minimizes profit...

Beyond Economic Efficiency in Biodiversity Conservation AgEcon
Gatzweiler, Franz W.; Volkmann, Jorg.
This paper aims at explaining the importance of the democracy stance as compared to the efficiency stance in order to deal with complexity in biodiversity conservation. While the efficiency stance refers to the realm of relatively simple systems, individual rationality, and instrumental values, the complexity stance transcends these boundaries into the realm of complex systems, social rationality and intrinsic values. We argue that the task of biodiversity conservation is impossible to achieve in economically efficient ways, because (a) it is impossible to come to a (fully informed) complete account of all values, not only because it is costly but also because (b) moral values are involved which (by their nature) exclude themselves from being accounted...

Agricultural land management strategies to reduce phosphorus loads in the Gippsland Lakes, Australia AgEcon
Roberts, Anna M.; Pannell, David J.; Doole, Graeme J.; Vigiak, Olga.
A target to reduce phosphorus flows into the Gippsland Lakes in south-eastern Australia by 40 per cent to improve water quality has previously been established by stakeholders. An integrated analysis at the catchment scale is undertaken to assess the agricultural land management changes required to achieve this target, and to evaluate the cost-effectiveness of these changes. It appears technically feasible to achieve a 40 per cent reduction in P load entering the lakes, but the least-costly way of doing so would require around A$1 billion over 20 years, a dramatic increase in the current levels of funding provided for management. On the other hand, a 20 per cent P reduction could be achieved at much lower cost: around $80 million over 20 years and...

The Rule of The Jungle in Pakistan: A Case Study on Corruption and Forest Management in Swat AgEcon
Pellegrini, Lorenzo.
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...
