“…One possible avenue to capture and evaluate the true willingness-to-accept (WTA) compensation is to use stated preference methods (Bakkegaard et al, 2012). Despite a growing application of stated preference studies addressing WTA payments in the form of CV (de Groot and Hermans, 2009;Gadaud and Rambonilaza, 2010;Bakkegaard et al, 2012;Bush et al, 2013), studies attempting to assess the WTA in the form of CE are highly uncommon, with Casey et al (2008) being one exception.…”

-Protection of mangrove forests entails the decrease and restriction of their injudicious uses by local people and therefore imposes opportunity costs on poor local communities, which often depend on these forest resources for their subsistence. This study aims to quantify the economic opportunity cost of conservation for coastal communities living in areas adjacent to mangrove forests in the southern coasts of Iran. The main commercial uses of the mangrove forests in this area are restricted to fishing, tourist boating trips, and limited leaves cutting. We applied a choice experiment method to measure the costs of the forest exploitation reduction under hypothetical protection scenarios in which local users would receive monetary compensation to lessen or forgo mangrove forest utilization. The results showed that local communities are willing to accept lower compensation when the protection is meant to decrease the frequency of Hara cutting and fishing, as opposed to banning recreational opportunities. The mean WTA was estimated to be 55 662 500 IRR.hsld −1 .yr −1 (2026 USD), which was generally lower than opportunity costs in the form of foregone income. Before implementing any policies related to equity, our findings can provide policymakers with useful prior knowledge and prescription.

La protection des forêts de mangroves entraîne la diminution et la restriction de leurs utilisations excessives par les populations locales et impose donc des coûts d'opportunité sur les communautés locales pauvres, qui dépendent souvent de ces ressources forestières pour leur subsistance. Cette étude vise à quantifier le coût d'opportunité économique de la conservation pour les communautés côtières qui vivent dans les zones adjacentes aux forêts de mangroves dans les côtes du sud de l'Iran. Les principales utilisations commerciales des forêts de mangroves dans cette région sont limitées à la pêche, aux voyages en bateau de tourisme, et à la coupe de feuilles réglementée. Nous avons appliqué une méthode d'expérimentation des choix pour mesurer les coûts de la réduction de l'exploitation forestière dans des scénarios hypothétiques de protection dans lesquels les utilisateurs locaux recevraient une compensation monétaire pour réduire ou renoncer à l'utilisation de la forêt de mangrove. Les résultats ont montré que les communautés locales sont prêtes à accepter une compensation inférieure lorsque la protection est destinée à diminuer la fréquence de la coupe du Hara et la pêche, par opposition à l'interdiction de possibilités de loisirs. La WTA moyenne a été estimée à 55.662.500 IRR.hsld −1 .yr −1 (2026 USD), ce qui était généralement plus bas que les coûts d'opportunité sous forme de manque à gagner. Avant la mise en oeuvre des politiques relatives à l'équité, nos résul...

“…However, the latter derives the WTP responses indirectly. Casey et al [23] employed the choice experiment method to assess the public WTP for avoiding the environmental risks caused by oil transport in the Amazon River. The marginal WTP estimates from reducing the chance of oil spills, reducing the size of oil spills, compensation for the education problems caused by oil spills, and compensation for the health problems caused by oil spills were USD 472, 214, 260, and 129 per household per year, respectively.…”

“…The SP methods usually ask people to state their WTP for consuming the goods or services concerned. Two representative approaches belonging to SP methods are the contingent valuation (CV) approach (e.g., [19][20][21][22]) and choice experiment (CE) approach (e.g., [23,24]). The former elicits the WTP response directly.…”

The Public Value of Reducing the Incidence of Oil Spill Accidents in Korean Rivers

2018

Oil spill accidents involving cars or boats for transport in rivers can contaminate drinking water sources. During the past ten years, an annual average of forty-six cases of oil spill accidents have occurred in Korean rivers. Because of this, the Korean government is seeking to reduce the incidence of oil spill accidents in rivers by half. This article aims to evaluate the public value of the reduction. Household willingness to pay (WTP) for the reduction was investigated, applying the contingent valuation approach. A survey of 1000 households was carried out in Korea. The data on the WTP were gathered using a dichotomous choice question and analyzed employing the spike model. The mean WTP estimate is obtained as KRW 6188 (USD 5.28) per household per annum, which is statistically meaningful. The total public value expanded to the population amounts to KRW 120.8 billion (USD 103.0 million) per year. The information can be utilized in policy-making and decision-making about the reduction of the incidence of oil spill accidents in rivers by half.

“…In general, oil and gas exploitation in the Amazon rainforest have caused environmental and social impacts (Killeen, 2007;Casey et al, 2008;Orta-Martínez and Finer, 2010). Oil in its raw state, also called "crude oil," is a complex mixture of hydrocarbons.…”

Tests of chronic and acute toxicity of crude oil on larvae of Chironomus kiiensis Tokunaga (Diptera: Chironomidae)

The Amazon region, known for its mega-biodiversity, also holds large reserves of petroleum and natural gas. The increasing exploitation of natural gas and crude oil in the Amazon has not been accompanied by studies evaluating the impact of these pollutants on local biological communities, particularly aquatic organisms. The aim of the present study was to determine the values of acute and chronic toxicity of crude oil from Urucu to larvae of Chironomus kiiensis Tokunaga, 1936. The LD50 48h of crude oil for second-instar larvae of C. kiiensis was 26.5 mg/L, and mortality for the majority of concentrations tested was greatest during the first 24 hours of the experiment. The survival of eggs of C. kiiensis exposed to concentrations of crude oil was also evaluated but did not differ significantly among the treatments. Despite the high tolerance observed for the species in the experiments, there is a possibility that in the natural environment the oil interacts with other factors, leading to synergistic effects, so further studies are needed to assess the effects of this pollutant on aquatic insect species.Keywords: petroleum, LC50, Chironomidae, Urucu, Amazon.Teste de toxicidade aguda e crônica de óleo cru em larvas de Chironomus kiiensis Tokunaga (Diptera: Chironomidae) ResumoA região Amazônica, conhecida por sua megabiodiversidade, também é detentora de grandes reservas de petróleo e gás natural. A crescente exploração de gás natural e óleo cru na Amazônia não é acompanhada de estudos avaliando o impacto destes poluentes nas comunidades biológicas locais, especialmente organismos aquáticos. Neste trabalho, o objetivo das autoras foi determinar os valores de toxicidade aguda e crônica de óleo cru proveniente de Urucu para larvas da espécie Chironomus kiiensis Tokunaga, 1936. A CL50 48h de óleo cru para larvas de segundo instar de C. kiiensis foi de 26,5 mg/L e a mortalidade para a maioria das concentrações testadas foi maior durante as 24 primeiras horas do experimento. A sobrevivência dos ovos de C. kiiensis expostos a concentrações de óleo cru também foi avaliada, porém sem diferença significativa entre os tratamentos. Apesar da alta tolerância da espécie observada nos experimentos, em ambiente natural existe a possibilidade do óleo interagir com outros fatores, apresentando efeito sinérgico, e mais estudos avaliando o efeitos deste poluente sobre insetos aquáticos são necessários.Palavras-chave: petróleo, CL50, Chironomidae, Urucu, Amazônia.
