“…Results of the Probit model without selection correction but considering V as an exogenous regressor are in the last column of Table 4. Details of the determinants of the selection equation are available in Garcia et al (2007). We only comment here on the estimation results concerning the DC question with sample correction.…”

“…We suspect that disturbances in each equation (decision to visit and DC question) are correlated. Garcia et al (2007) show efficiency gains in the estimation procedure using a simultaneous bivariate Probit equation model. If we want to compare the WTP of each group of respondents in the case where forest visitors and non-visitors are not drawn from the same population, then the sample selection problem should be accurately dealt with.…”

“…The background of this national survey of non-market goods and services in French forests has been given elsewhere (Peyron et al, 2002;Garcia et al, 2007). The main objectives of the survey were to (1) value recreation in French forests using travel cost methods and underline the differences between the main regions of France, considering households' visits over two consecutive years and (2) value biodiversity in French forests using a contingent valuation (CV) analysis.…”

In this article, we use two formats of contingent valuation (CV) questions to elicit willingness to pay (WTP) for maintaining biodiversity in forests: the dichotomous choice (DC) or referendum format and the open-ended (OE) question. A large population of French households were surveyed nationwide by phone. The sample of respondents was later divided into two subsamples: people who have recreational activities in forests and those who do not. This dichotomy potentially biases WTP as the decision to have recreational activities in forests is endogenous. We estimate a Probit model with sample selection to correct this bias in the DC question. With the OE question, a second source of selection bias related to non-random censoring is present: some respondents are unwilling to pay. We use an extension of Heckman's approach to the double selection problem. The empirical application shows that ARTICLE IN PRESS www.elsevier.de/jfe 1104-6899/$ -see front matter (S. Garcia).ignoring these sample selection problems leads to biased estimates of mean WTP for biodiversity in a national survey for France.

The effect of riparian woodland cover on ecosystem service delivery by river floodplains: a scenario assessment

et al. 2021

View full text Add to dashboard Cite

Sixteen ecosystem services were quantified for the riverine landscapes of the Nahe, Stever (Germany), Bresse plain, and Azergues (France), to assess the effects of riparian woodland cover. Future woodland cover in 2050 was modeled to reflect contrasting scenarios of river management aligned to the well‐established shared socioeconomic pathways. The scenarios are labeled as current, pessimistic, best practice, and ambitious riparian management practices (RMPs). We linked services to floodplain land use and river morphology and quantified them separately for spatial segments (0.5–1 km in length, n = 118–3419, depending on river length), using an analytical framework, the “Mononen cascade.” Conservative monetary value estimates were based on net producer income before tax and subsidy, a shadow market price for carbon, flood damage functions, or willingness to pay for recreation and non‐use. Most services were linked to land use, some affected the value of other services through simple rules (woodland shade affected trout survival hence angling benefit, a minimum of woodland affected pest regulation, hence crop productivity). In the current landscape state, provisioning, regulating, and cultural services all showed optimum curves with woodland cover: Provisioning services and cultural services were maximal around 45%, whereas this was around 30% for regulating services. More woodland was present in steeper near‐source segments. Averaged across rivers, mean total service provision was estimated at 1084 ± 4 €·ha−1·yr−1, with 40%, 36%, and 24% contributed by, respectively, provisioning, regulating, and cultural services. The three scenarios led to a limited change in total ecosystem service delivery, even if mean woodland cover was reduced from 27% to 17% in the pessimistic RMP and increased to 70% in the ambitious RMP for the most extreme case of the Stever. Provisioning services declined with increased woodland cover and cultural services increased. Regulating services did not change that much, because they are dominated by flood prevention in our assessment. The “best practice” scenario appeared to combine a modest increase in cultural services with a slight increase in provisioning service. An ambitious nature conservation objective as in the ambitious RMP appears possible without seriously compromising overall societal benefit.
