A Cautionary Note on Individual Transferable Quotas Ecology and Society
Sumaila, U. Rashid; UBC Fisheries Centre, University of British Columbia; r.sumaila@fisheries.ubc.ca.
Individual transferable quotas (ITQs) are a type of catch share system, which is a tool used by some governments to manage fisheries. Technical reasons for taking a rather cautious approach to the implementation of ITQs have been provided previously. In the current contribution, I first highlight the strengths and weaknesses of ITQs and then provide suggestions on how to design and implement these quotas to mitigate their weaknesses. ITQs need to be designed carefully as part of a broad ecosystem-based management scheme to meet the three generally accepted objectives of modern fisheries management: ecological, economic, and social sustainability.

A CHOICE-EXPERIMENT BASED ANALYSIS OF PROTECTION MOTIVATION THEORY: HEALTH RELATED BEHAVIOR OF CONSUMERS WITH CELIAC DISEASE AgEcon
Zhang, Jing; Steiner, Bodo E..
The underlying components of protection motivation theory (PMT; Rogers 1983) are explored through choice experiment-based analysis within a random utility framework, to account for some of the motivational, cognitive, and affective processes that likely affect celiacs’ propensity to use a novel health-risk reducing product. Those four groups of variables that are aimed to capture threat appraisal and coping appraisal processes as part of the standard PMT (Rogers 1975, 1983; Floyd et al. 2000) are found to contribute significantly to explaining the adaptive response of celiacs. Self-assessed vulnerability and perceived product efficacy form a most significant part of respondents’ threat appraisal process. Standard socio-demographic and lifestyle...

A Collaborative Breeding Strategy for Organic Potatoes in the Netherlands Organic Eprints
Lammerts van Bueren, E.T..
The ability of the organic farmer’s agronomic toolbox to reduce the susceptibility of a potato crop to late blight is limited, certainly under the Dutch climatic conditions. Conventional breeding programs do not generate either a sufficient number nor appropriate types of resistant varieties for organic systems; and a separate breeding program for the limited area of organic potato production is simply not viable. Therefore, all concerned forces have joined together in an umbrella program called Bioimpuls for organic potato improvement.

Brief biographical data is given, of the artists, engravers and collectors named on the plates. The French and Dutch publications are not only translated re-editions, but emended, complementary editions of the German work. Many figures of the plates are iconotypes.

A colonização do mundo rural e a emergência de novos atores. Organic Eprints
Brandenburg, Alfio.
Este texto tem por objetivo problematizar a noção de mundo rural e analisar as condições de emergência de novos atores. A partir da ideia de colonização do rural, os personagens que reagem ao processo de racionalização unilateral da vida social e biológica são definidos como novos atores, na medida em que reconstroem relações com o ambiente social e natural. A ação de novos atores inscreve-se no contexto de um campo de disputa de linguagens ecossociais e de distintas ruralidades, construindo-se uma racionalidade que se contrapõe ao domínio da racionalidade instrumental: a racionalidade ambiental ou ecológica.

A community of biocurators Nature Precedings
Pascale Gaudet.
Biocuration is a difficult mission: biological data is highly heterogeneous, and there are few areas where guidelines for data preservation and exchange exist. This has hampered the speed, quantity and diversity of data possible to capture. Hence, a major challenge for the biocuration community is to explore innovative ways to capture, represent and display information. It is also essential to increase the involvement of researchers, publishers and funding agencies in this process. I will discuss the work of the International Society for Biocuration to build a community of biocurators to achieve these goals.

A co-modelling process of social and natural dynamics on the isle of Ouessant: Sheep, turf and bikes ArchiMer
Rouan, Mathias; Kerbiriou, Christian; Levrel, Harold; Etienne, M.
An interdisciplinary team has applied the multi-agent system formalism to study shrub encroachment in the Biosphere Reserve on the isle of Ouessant. The main goals were (1) to understand vegetation dynamics, and (2) to represent how main agents, or actors view the dynamics of natural resources in relation to their own living practices. The management strategies established for each type of stakeholders were formalised and the impact of these strategies on biodiversity was analyzed at various temporal and spatial scales. Following a short description of the model, three aspects of the modelling process are discussed in more detail: the use of the chough (Pyrrhocorax pyrrhocorax) population as a representative variable for the interactions between...

A comparative study of farm nutrient budgets and nutrients flows of certified organic and non-organic farms in China, Brazil and Egypt Organic Eprints
Oelofse, Myles; Høgh-Jensen, Henning; de Abreu, L.S.; de Almeira, G.F.; Hui, Q.Y.; de Neergaard, Andreas.
Increased demand for certified organic products has led to an increase in the number of certified organic farms in developing countries. Knowledge of farmer nutrient management practices on certified organic farms in developing countries is limited. Thus, the aim of this study was to investigate the impact of the adoption of certified organic agriculture on farm nutrient flows and nutrient budgets, and evaluate to which degree organic farms comply with organic principles relating to nutrient management. The study is based on five case studies of different types of certified organic farming systems in Brazil, Egypt and China. Farm nutrient flows and nutrient budgets for nitrogen, phosphorous and potassium were created for each farm. Four of the five...

A Comparison of Methodologies for Valuing Decreased Health Effects from Wildfire Smoke AgEcon
Richardson, Leslie; Loomis, John B.; Champ, Patricia A..
Wildfire seasons are becoming longer and more intense throughout the world, making it increasingly important to monetize the full damages caused by wildfires when analyzing various fire management policies. We estimate the economic costs of the health effects associated with exposure to wildfire smoke using a simple cost of illness approach and for the first time to our knowledge we estimate willingness-to-pay (WTP) for a decrease in symptom days from wildfire smoke using the contingent valuation method and the averting behavior method. Comparing estimates across all three common approaches for estimating the economic cost of exposure to an air pollutant is an important contribution to the literature. This study uses data from the largest wildfire in Los...

A Comparison of Parametric Approximation Techniques to Continuous-Time Stochastic Dynamic Programming Problems AgEcon
Kompas, Tom; Chu, Long.
We compare three parametric techniques to approximate Hamilton-Jacobi-Bellman equations via unidimensional and multidimensional problems. The linear programming technique is very efficient for unidimensional problems and offers a balance of speed and accuracy for multidimensional problems. A comparable projection technique is shown to be slow, but has stable accuracy, whereas a perturbation technique has the least accuracy although its speed suffers least from the curse of dimensionality. The linear programming technique is also shown to be suitable for problems in resource management, including applications to biosecurity and marine reserve design.
