Worshipping the Tiger: Modeling Non-use Existence Values of Wildlife Spiritual Services
研究了印度索利加部落因崇拜老虎而产生的精神存在价值，构建生态经济模型估算老虎的存在价值，并分析不同管理情景下老虎种群动态，为保护政策提供参考。
Abstract Several indigenous tribes around the world derive spiritual value from revering fauna and flora species. Species conservation is not a prime objective of such traditions but can be an unintended consequence. Conventional species conservation practices ignore this spiritual value and tribes are often evicted from protected areas. We use the existence value framework to develop a coupled ecological-economic model of the use and non-use, existence values of wildlife for a tribe that derives spiritual value from a wildlife population. We calibrate the model for the Biligiri Rangaswamy Temple (BRT) Tiger Reserve in India with the resident Soligas tribe who consider tigers as sacred and back out an existence value of tigers in this reserve from a tribe manager’s perspective. The model ascertains tiger population dynamics under several management scenarios. Steady-state convergence is observed under secure property rights for the Soligas. Scenarios in which they are evicted from the BRT reserve and lose their property rights yields localized tiger extinction. Finally, we generate a marginal existence value function and discuss the potential for using existence value estimates in guiding conservation policy.
