Valuing riparian forests restoration: a CVM application in Corumbatai river basin

Abstract

Abstract:This study is an application of CVM to a specific area in Brazil, the Corumbatai river basin, in the state of Sao Paulo, aiming to estimate the value attached by affected people to a hypothetical riparian forest restoration project. The method used was the double bounded dichotomous choice under a logit model. Data were obtained by street-intercept interviews with a net sample of 930 individuals, 20 years or older, living in seven municipalities (cities and respective rural areas) that contain the basin. Protest bid responses were not excluded in a first approximation, resulting in a R$ 2.06 mean willingness to pay (WTP) for the riparian forest restoration, equivalent to approximately R$ 274,000 per month (R$ 1.00 equivalent to US$ 0.52 at the survey period) when accounting for about 133,000 residences in the area. It was observed an expressive number of "no-no" responses from people ascribing the problem to government and farmers and suspecting on misuse of funds by the official agencies involved. Key

Evaluation of Forest Preservation in Cambodian Rural Villages

“…First, studies by Yoeu et al (2010), Muranaka and Terawaki (2005), Linde-Rahr (2008), and Amiri et al (2015) show household income to be a significant positive variable for participation in forest preservation. In contrast, Brugnaro (2010) reports household income as a significant negative variable. Yoeu et al (2010) measured farmers' willingness to pay (WTP) with regard to the flooded forests in Cambodia's Tonlé Sap Lake region using single-bounded dichotomous-format CVM.…”

“…On the other hand, Brugnaro (2010) reported that household income was a significant negative variable. He investigated local residents' WTP to restore the forests of the Corumbatai river basin in Brazil.…”

“…The selection of the exogenous variables from the abovementioned model is based on the works of Poe et al (2002), Silva (2003), Horton et al (2003), Cirino and Lima (2008), Brugnaro (2010), Bhandari and Heshmati (2010).…”

Evaluation of the Visitation Rate in the Park by the Travel Cost Method in Parque Do Sabiá Complex, Uberlândia, Minas Gerais, Brazil

“…1-Leisure, with recreational and sports activities; 2-Environmental, due to the presence of flora and fauna, with contemplation activities; and 3-Economic, when there is prominence for free and unrestricted use of the various areas of the park 1 According to Botti (2010). 2 According to IBGE methodology (2010). 3 The smaller numeric value is the zone or neighborhood closest to the park, and it increases as the zone or the neighborhood is further from the park and the access routes more difficult.…”
