Valuation of non-priced amenities provided by the biological resources within the Monteverde Cloud Forest Preserve, Costa Rica

International Ecotourism and the Valuation of Tropical Rainforests in Costa Rica

“…This resulted in a total yearly U.S. ecotourism value of $4·5 million for the Monteverde Cloud Forest Reserve. This result is greater than that found by Echeverria et al (1995), who used contingent valuation to estimate an annual ecotourism value of $2 million for Monteverde.…”

Estimation of conservation value of myrtle (Myrtus communis) using a contingent valuation method: a case study in a Dooreh forest area, Lorestan Province, Iran

“…In contrast, people with low incomes were rather more concerned to give priority to satisfy their basic needs. This results was consistent with what many investigators such as Echeverria et al (1995), Lehtonen et al (2003), Leong et al (2005) Furthermore, smaller households with their relatively lower daily expenditures were willing to pay more for myrtle habitat conservation compared to larger households. All the same, if larger households had a higher level of income, they were also willing to pay more despite their relatively larger family size.…”

“…In general, the higher their education, the higher their WTP and the more their tendency to preserve the environment. Similar results were found by Echeverria et al (1995), Lehtonen et al (2003), Leong et al (2005), Tao et al (2012), Chukwone andOkorji (2008), Peron and Esmeili (2010), Molaei (2009), and Khosravi and Sabouhi (2011).…”

“…In contrast, the estimated WTP per household per year and the conservation value per hectare estimated by us were higher than those mentioned by Echeverria et al (1995) and Molaei (2009), apparently because these studies were more recent than those mentioned earlier.…”

“…For example, Echeverria et al (1995) estimated the value of existence benefits in Costa Rica's forests, based on a Contingent Valuation (CV) method and came up with a value of $238 per hectare of forest per year. Lehtonen et al (2003) estimated the average conservation value of forests in southern Finland in terms of the willingness to pay at $23.80 per household per year, using CV in conjunction with Double Bounded Dichotomous questionnaires and a logit regression model.…”
