Social Desirability and Environmental Valuation

Socially desirable responding (SDR) is an often-reported source of bias in survey interviews. It describes the tendency of a respondent to answer in a way that is socially desirable rather than to answer truthfully. This response bias also threatens the reliability and validity of survey-based environmental valuation techniques such as the Contingent Valuation Method (CVM). Therefore, the study deals with the assessment of the conditions for the occurrence of SDR in CVM interviews. A behavioral model is devised to take into account a set of factors triggering SDR responses. The impact of these factors of SDR on willingness to pay (WTP) responses is tested. The results reveal that the relevant factors do not affect WTP statements simultaneously but rather influence them in an independent manner. These findings can improve future CVM studies by identifying respondents who are prone to be influenced by SDR

The ecological price of getting rich in a green desert : a contingent valuation study in rural Southwest China

The cultivation of rubber trees in Xishuangbanna Prefecture in China?s Yunnan Province has triggered an unprecedented economic development but it is also associated with severe environmental problems. Rubber plantations are encroaching the indigenous rainforests 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 these environmental costs of the economic progress in Xishuangbanna. To this end a Contingent Valuation survey is conducted to elicit local residents? willingness to pay for a reforestation program that converts existing rubber plantations back into forest. It is shown that though local people's awareness of the environmental problems caused by increasing rubber plantation is quite high their willingness to pay in order to change things is rather low. It seems that from the perspective of local residents the economic advantages of rubber cultivation outweigh the resulting environmental threats. Another explanation of the low willingness to pay stated in this survey might be the fact that many respondents consider taxes and fees already too high in China so that they are not willing to make any further contributions to whatever purpose

The influence of ethnicity and culture on the valuation of environmental improvements : results from a CVM study in Southwest China

The provision of environmental goods by government creates social benefits which might vary between citizen groups with different cultural and ethnic backgrounds. 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 these ethnic groups

Valuing conservation benefits of an offshore marine protected area

Increasing anthropogenic pressure in the offshore marine environment highlights the need for improved management and conservation of offshore ecosystems. This study scrutinises the applicability of a discrete choice experiment to value the expected benefits arising from the conservation of an offshore sandbank in UK waters. The valuation scenario refers to the UK part of the Dogger Bank, in the southern North Sea, and is based on real-world management options for fisheries, wind farms and marine protection currently under discussion for the site. It is assessed to what extent the general public perceive and value conservation benefits arising from an offshore marine protected area. The survey reveals support for marine conservation measures despite the general public's limited prior knowledge of current marine planning. Results further show significant values for an increase in species diversity, the protection of certain charismatic species and a restriction in the spread of invasive species across the site. Implications for policy and management with respect to commercial fishing, wind farm construction and nature conservation are discussed

Assessing costs and benefits of measures to achieve good environmental status in European regional seas: challenges, opportunities, and lessons learnt

The EU Marine Strategy Framework Directive (MSFD) requires Member States to assess the costs and benefits of Programmes of Measures (PoMs) put in place to ensure that European marine waters achieve Good Environmental Status by 2020. An interdisciplinary approach is needed to carry out such an assessment whereby economic analysis is used to evaluate the outputs from ecological analysis that determines the expected effects of such management measures. This paper applies and tests an existing six-step approach to assess costs and benefits of management measures with potential to support the overall goal of the MSFD and discusses a range of ecological and economic analytical tools applicable to this task. Environmental cost-benefit analyses are considered for selected PoMs in three European case studies: Baltic Sea (Finland), East Coast Marine Plan area (UK), and the Bay of Biscay (Spain). These contrasting case studies are used to investigate the application of environmental cost-benefit analysis (CBA) including the challenges, opportunities and lessons learnt from using this approach. This paper demonstrates that there are opportunities in applying the six-step environmental CBA framework presented to assess the impact of PoMs. However, given demonstrated limitations of knowledge and data availability, application of other economic techniques should also be considered (although not applied here) to complement the more formal environmental CBA approach
