It is well-known that operating within the boundaries of a national park provides commercial actors with the opportunity to charge a price premium, though this has to a lesser degree been demonstrated for marine protected areas.
Knowledge of people's understanding of environmental problems is vital for the effective implementation of the ecosystem approach to marine management. This is especially relevant when conservation goals are aimed at ecosystems in the deep-sea that are remote to the consciousness of most people. This study explores public perceptions of the deep-sea environment among the Scottish and Norwegian public.
We measure people's pro-social behavior, in terms of voluntary money and labor contributions to an archetypical public good, a bridge, and in terms of voluntary money contributions in a public good game, using the same non-student sample in rural Vietnam at four different points in time from 2005 to 2011. Two of the observed events are actual voluntary contributions (one in terms of money and one in terms of labor), one is from a natural field experiment, and one is from an artefactual field experiment.
The prime objective of this paper is to estimate from a cross-country perspective the willingness to pay for marine turtle conservation using the contingent valuation method. A secondary objective is to investigate two methodological issues about contingent valuation study: scope effect and payment vehicle effect. Using a uniform survey instrument and protocol, a sample of 3680 respondents from Beijing (China), Davao City (Philippines), Bangkok (Thailand) and Ho Chi Minh/Hanoi (Vietnam) were interviewed.
This study measures the public preferences for cultivated land protection as a case study of Wenling City, China, using the choice experiment (CE) approach. The estimation results indicate that the most important attribute for cultivated land protection in Wenling City was land facility, followed by land fertility and then by landscape improvement.
While the compensatory model of choice dominates the environmental valuation literature, non-compensatory models, where individuals do not tradeoff one attribute for another, are sometimes found to be better representations of choice behavior. Most non-compensatory models employ “cutoffs”, the point at which utility abruptly changes. But cutoffs are usually elicited directly from respondents using a stated preference question. Such elicitation could be inaccurate and might introduce bias to the decision process. In this article, we develop a model that estimates cutoff levels endogenously.
This study investigates how factors that influence farmers’ intentions to adapt to climate change differ from each other in regions with different levels of vulnerability to climate change. Data were collected from interviews with 598 rice farmers in Dong Thap, Soc Trang and Long An provinces in the Mekong Delta, Vietnam. These provinces were identified respectively as highly, moderately and mildly vulnerable to climate change. Multi-group structural equation modelling was employed.
Chronic wasting disease (CWD) is a prion disease that affects deer, elk and other cervid wildlife species. Although there is no known link between the consumption of CWD affected meat and human health, hunters are advised to have animals from CWD affected areas tested and are advised against consuming meat from CWD infected animals (Government of Alberta 2010). We model hunter response to the knowledge that deer in a wildlife management unit have been found to have CWD in Alberta, Canada.
This research described in this article aimed to investigate international market potentials for Pangasius catfish (Pangasianodon hypopthalmus). The monthly export data from Vietnam, which accounts for more than 95% of the global export value, in the period 2007 to 2014, were used to estimate a non-linear Inverse Almost Ideal Demand System of the seven market regions.
