Based on a case study carried out on the Lac Saint-Pierre (LSP) World Biosphere Reserve (Québec, Canada), this paper estimates ecosystem service loss, more precisely the loss related to cultural and recreational activities of the LSP due to the fall of its water level under the pressure of climate change. We measure two dimensions of this loss. As a first step, the extrapolation of our representative survey reports $100 million annual loss in terms of recreation revenue due to the trip reduction to LSP, which is about 60% of current level. Subsequently, the travel-cost data and the contingent behavior data are combined in a revealed and stated behavior panel random-effect estimation, which reports an additional loss measured by consumer surplus that visitors can obtain from their trips up to $232 million, signifying 42% of reduction in their current value.

用公开和陈述的行为数据衡量气候变化下的娱乐效益损失：Lac Saint-Pierre 世界生物圈保护区的案例（加拿大魁北克）

本文基于对 Lac Saint-Pierre (LSP) 世界生物圈保护区（加拿大魁北克）进行的案例研究，估算了生态系统服务损失，更准确地说是由于其水位在气候变化的压力下。我们测量了这种损失的两个维度。作为第一步，我们的代表性调查的推断报告称，由于 LSP 旅行减少，娱乐收入每年损失 1 亿美元，约为当前水平的 60%。随后，将旅行成本数据和或有行为数据结合在一个揭示和陈述的行为面板随机效应估计中，该估计报告了以消费者剩余衡量的额外损失，游客可以从他们的旅行中获得高达 2.32 亿美元的损失，
