Rubber plantations are encroaching the indigenous rain forests at a large scale and a high speed in Xishuangbanna. Many rare plant and animal species are endangered by this development, the natural water management is disturbed, and even the microclimate in this region has changed over the past years. The present study aims at an assessment of the environmental benefits accruing from a reforestation project partly reversing the deforestation that has taken place over the past years. To this end, a Contingent Valuation survey has been conducted in Xishuangbanna to elicit local residents' willingness to pay for this reforestation program that converts existing rubber plantations back into forest. It is shown that local people's awareness of the environmental problems caused b...

In CVM studies, the social value of a project is typically assessed as the aggregate willingness to pay of the affected households for this project. However, the transferability of this method from the socio-economic context of industrialized countries, where it was originally applied, to developing and emerging countries must be scrutinized. This paper highlights a number of problematic issues that arise in the context of applying the CVM in developing and emerging countries. The theoretical considerations are exemplified by two practical valuation studies conducted in northern Thailand as a representative of an emerging country and in a rural area of the Philippines as a representative of a developing country.

The philosophy that subsidies for the agricultural sector should be calculated not only by agricultural market production but also according to agricultural noncommodity production like e.g. the conservation of the countryside, makes it

Yet, it is still an open question whether this practice biases contingent valuation survey responses, especially stated willingness to pay (WTP) for the respective environmental good. This study employs a set of field experiments to investigate the effect of respondent incentives in the form of monetary and in-kind gifts on responses in a contingent valuation survey. It is analyzed how these different kinds of incentives affect (1) respondents’ diligence when answering CVM questions, (2) the likelihood of a respondent to state a positive WTP, and (3) the amount of stated WTP. Results show that with respect to raising respondents’ diligence in the survey interview a moderate monetary ...

These differences as well as the overall extent of benefits should be analysed before the implementation of public projects in order to consider not only the efficiency aspects of such a project but also its distributional effects. In Southwest China we are facing a rapid deforestation for the development of rubber cultivation and at the same time find an ethnically highly diverse population. This Contingent Valuation study tries to assess the short-term and long-term benefits accruing from a public reforestation programme in Xishuangbanna and their distribution among different ethnic groups living in that region. The results show that different ethnic groups value short-term and future benefits of reforestation differently and that these differences can be explained by the different cultural and historical backgrounds of ...
