Contributions of park constructions to residents' demands of ecosystem services consumption: A case study of urban public parks in Beijing.

ABSTRACT: Urban public parks can provide convenience for residents to get close to nature and provide places for daily ecosystem services. It is of practical and theoretical significance to choose urban public parks as the entry point to explore the changing trends and supply paths of urban residents' daily ecosystem service consumption. Based on the government 's research? of urban public parks in Beijing from 1993 to 2018, this study explores the residents' ecosystem services consumption demands and the contributions of park constructions to these demands. The results show that: (1) in the past 25 years, the frequency, duration, participation rate, and evaluation of people's daily ecosystem service consumption have increased significantly. In other words, the ecosystem services demands are increasing. (2) different constructions of a park have distinct contributions to the increasing demands of ecosystem service consumption. The contributions from constructions of the natural landscape and the infrastructure have been in decline since 1993, yet they contribute the most to the demands of residents' ecosystem services consumption until 2018. The contributions made by constructions of management and maintenance, and transportation around urban public parks have been on the rise and the significant points occurring after the 2008 Olympic Games. Our research proposes a method to determine the relation between the demands of residents' ecosystem services consumption and the contributions of park constructions to these demands, which has significant implications for optimizing the constructions of urban public parks to better meet the demands of ecosystem services consumption.

Project description:When balancing environmental preservation and economic development, it is critical to evaluate how taxpayers value national park land and for what they are valuing it. One key component of this evaluation is to calculate a "passive use value," or the willingness to pay (WTP), for protection of land that may never directly be used, and to determine what benefits of land protection motivate this passive use value. We estimated the WTP for a 5% expansion of Denali National Park in Alaska (an expansion of 325,340 acres) using a questionnaire and the contingent valuation method. The survey first educated respondents on Alaskan geography, the current status of protected land and wildlife in Alaska, and common arguments for and against National Park expansion. The survey then described a proposal to expand the Denali National Park and asked a series of questions designed to bound the respondents WTP. Finally, the survey asked respondents to answer questions about what motivated their support or disapproval for the program. Multiple methodologies were used to estimate the national average WTP, resulting in a WTP range of a single payment of $77 to $409. This is estimated to be a total WTP of $15.1 billion to $79.3 billion for all individuals aged 18 to 64 in the United States, or $363.1 million to $1.91 billion per year in 2017 dollars. Respondents to the survey indicated that their support is driven primarily by increased protection from oil spills (85.8% deemed this very important or important), by increasing and protecting Alaska's biodiversity (84.3%), and preserving Alaska's beauty (84.2%). These results can help inform recent, current, and future debates about land use. President Obama significantly expanded land protections, while President Trump is continuing to scale back land protections, including opening up untouched land in Alaska in the Arctic National Wildlife Refuge for oil drilling. These results suggest that there are significant passive use values that should be considered when deciding whether to expand or reduce protection of land. Given that passive use values are significant, this suggests that the economic benefits must be large to tip a cost-benefit analysis in favor of reduced land protections.
