摘要

保护野生动植物是当前最紧迫的问题之一,但由于缺乏市场价格,野生动植物保护的经济价值往往被忽视,因为为生物多样性或整个生态系统设定经济价值是一项挑战。尽管如此,对野生动物进行估值对于改善保护领域的决策具有重要意义,因为它可以提供一个基于经济原则的补充视角。观鲸为野生动物的经济估值提供了一个机会。具体来说,它提供了一个框架,在这个框架中,经济收入可以通过购买观鲸游的游客的直接和间接支出来估算目标鲸目动物的经济价值。在此,我们根据直布罗陀海峡(西班牙)观鲸公司的三个主要目标物种:长鳍领航鲸(Globicephala melas)、普通海豚(Delphinus delphis)和虎鲸(Orcinus orca)的种群丰度进行了经济分析。这些物种的年总收入分别为 4 089 056 欧元、1 876 833 欧元和 505 389 欧元,每个个体每年平均收入分别为 14 048 欧元、951 欧元和 36 099 欧元。考虑到预期寿命,这相当于人口一生的总价值分别为 112,426,185 欧元、16,685,147 欧元和 19,171,107 欧元。这些价值说明了鲸类动物对当地经济的潜在贡献,但只代表其基于旅游业的非消费价值。我们的研究结果强化了这样一种观点,即应根据《关于养护、可持续利用海洋生物多样性公约》(ACCOBAMS)的高质量观鲸要求,促进可持续的高质量观鲸文化,以确保直布罗陀海峡鲸目动物种群的可持续发展、稳定的经济收入和生存能力。

The non-consumptive economic value of wildlife: the case of three cetacean species
The conservation of wildlife is one of the most pressing issues in the current times, but wildlife conservation economic values have often been largely ignored due to an absence of market prices, as setting an economic value on biodiversity or whole ecosystems can be challenging. Nevertheless, valuing wildlife can be of great significance to improve decision-making in the conservation field, as it can provide a complementary perspective based on economic principles. Whale-watching provides an opportunity for the economic valuation of wildlife. Specifically, it offers a framework in which the economic revenue allows the economic valuation of the targeted cetaceans to be estimated through the direct and indirect expenditure of the tourists who purchase whale-watching tours. Here, we performed an economic analysis based on population abundances of the three main species targeted by the whale-watching companies in the Strait of Gibraltar (Spain): long-finned pilot whales (Globicephala melas), common dolphins (Delphinus delphis) and killer whales (Orcinus orca). These species generated a total annual income of €4,089,056, €1,876,833, and €505,389, respectively, and each individual would generate an average of €14,048, €951, and €36,099 each year, respectively. Incorporating life expectancy, this corresponded to a total population value of €112,426,185, €16,685,147, and €19,171,107, respectively, over their lifetime. These values provide an idea of the potential contribution of cetaceans to the local economy but only represent their non-consumptive value based on tourism. Our results reinforce the idea that a sustainable, high-quality whale-watching culture, under ACCOBAMS High-Quality Whale-Watching requirements, should be promoted to ensure a sustainable industry, stable economic income and the viability of cetacean populations in the Strait of Gibraltar.
