Assessing programmes for the provision of agri-environmental services – An efficiency analysis realized in Southern Germany 31
Kantelhardt, Jochen; Eckstein, Karin; Hoffmann, Helmut.
Agricultural land use does not only concern farmers, but is of high relevance for the environment. Agri-environmental programmes aim to foster the environmental soundness of agricultural production. The aim of this study is to analyse the impact of agri-environmental programmes on the economic and the environmental performance of farms. Using the nonparametric method of Data Envelopment Analysis (DEA), we calculated the economic as well as the environmental efficiencies of farms and examined whether farms are able to succeed in combining environmental and economic efficiency. As study object serves a South German agri-environmental programme, the Bavarian KULAP. A farm survey was conducted covering a total of 102 farmers. The results show that farmers who...

Environmental Efficiency Among Corn Ethanol Plants 31
Sesmero, Juan P.; Perrin, Richard K.; Fulginiti, Lilyan E..
Economic viability of the US corn ethanol industry depends on prices, technical and economic efficiency of plants and on continuation of policy support. Public policy support is tied to the environmental efficiency of plants measured as their impact on emissions of greenhouse gases. This study evaluates the environmental efficiency of seven recently constructed ethanol plants in the North Central region of the U.S., using nonparametric data envelopment analysis (DEA). The minimum level of GHG emissions feasible with the available technology is calculated for each plant and this level is used to decompose environmental efficiency into its technical and allocative sources. Results show that, on average, plants in our sample may be able to reduce GHG...

Evaluierung von Agrarumweltprogrammen auf Grundlage der Umwelteffizienz landwirtschaftlicher Betriebe 31
Francksen, Tammo; Latacz-Lohmann, Uwe.
This paper sets out to develop an economic framework for ex post evaluations of agri-environmental schemes. We begin by developing a non-parametric model for estimating farm-level environmental efficiency scores. We then use this efficiency framework to devise a set of economic criteria for evaluating agri-environmental schemes. One key criterion is whether an environmental scheme has given rise to an increase in environmental efficiency scores across participating farms, relative to a counterfactual group of non participants. We finally demonstrate the potential usefulness of the framework by applying it to a fictitious multiple-objective conservation programme. The dataset is made up of 100 fictitious farms, half of which participate in the environmental...

Bayesian Estimation of Technical Efficiency of a Single Input 31
Kurkalova, Lyubov A.; Carriquiry, Alicia L..
We propose estimation of a stochastic production frontier model within a Bayesian framework to obtain the posterior distribution of single-input-oriented technical efficiency at the firm level. The proposed method is applicable to the estimation of environmental efficiency of agricultural production when the technology interaction with the environment is modeled via public inputs such as soil quality and environmental conditions. All computations are carried out using Markov chain Monte Carlo methods. We illustrate the approach by applying it to production data from Ukrainian collective farms.

Voluntary Agreements and the Environmental Efficiency of Participating Farms 31
Roosen, Jutta; Ordonez, Andrea.
Voluntary environmental agreements have been popular with government agencies in several countries. However, many questions remain about their efficiency as a regulatory tool. Recent analyses suggest that they are more effective than conventional regulatory or economic approaches when dealing with diffuse pollution and when innovation processes at the source are necessary to define effective regulation. This paper applies an activity-based framework to assess the contribution of such a voluntary agreement to the environmental performance of farms participating in a whole farm plan in the Southern part of Belgium. Using a cross-section of 52 farms, our results show that farms entering into environmental agreements are environmentally more efficient than...

Common moist diet replacement to promote sustainable Cobia Rachycentron canadum (Linnaeus) near- shore farming in Brazil 63
Landuci,Felipe Schwahofer; Rombenso,Artur Nishioka; Pontes,Marcelo Duarte; Maia,Marcelo Pereira; Eler,Giselle; Araujo,Bruno Cavalheiro; Poersch,Luis Henrique da Silva.
ABSTRACT: Cobia is one of the most promising warm water aquaculture species. In Brazil, cobia farming began in 2008 in the state of Rio de Janeiro from experimental scale facilities to regular near-shore farms based on fresh/frozen fish diets composed mostly of Sardinella sp. Despite the encouraging results achieved in the promotion of sustainable cobia farming, we advocate the replacement of fresh/frozen fish by a practical formulated feed. This experiment evaluated the zootechnical performance and environmental efficiency of moist and practical formulated feeds in early grow-out phases in the cycle of cobia nearshore cage culture. Four hundred and twenty juvenile cobia (151 ± 7 g) were fed with moist feed and practical formulated feed for 56 days....
