This paper examined consumers’experiences in and preferences for plant-based meat(PBM)food and their respective correlates,based on data from an online survey of 579 consumers in four major cities in China in early 2021.We first described consumers’experiences in consuming and purchasing PBM food and their correlates,and then analyzed consumer preferences using hypothetical choice experiment.The experiment offered consumers various options to purchase burgers made from PBM or animal-based meat(ABM),combined with different countries of origin(COO),taste labels,and prices.Our data showed that respondents hold overall positive attitudes toward PBM food;85 and 82%of respondents reported experience in eating and purchasing PBM food,respectively.More than half of them ate PBM food because they wanted to try new food(58%),or were interested in healthy food(56%).Income,religion,and dietary restrictions were significantly correlated with consumers’experiences in PBM food consumption.Results from the Random Parameter Logit Model based on the hypothetical choice experiment data showed that 79%of respondents chose PBM burgers and were willing to pay an average of 88 CNY for a PBM burger.We also found that 99.8 and 83%of respondents are willing to buy burgers made in China and those with a taste label,with a willingness to pay(WTP)of 208 and 120 CNY,respectively.The heterogeneity test revealed that females and those with at least a bachelor’s degree,higher income,religious beliefs,and dietary restrictions are more likely to buy PBM burgers than their counterparts.

Understanding Farmers’ Preferences Towards Insurance Schemes that Promote Biosecurity Best Management Practices

International Journal of Disaster Risk Science 2022年第5期13卷 705-715页

Plant pest and disease outbreaks,which occur with increasing frequency and intensity,cause catastrophic losses and threaten food security in many areas around the world.These impacts are expected to be exacerbated by climate change.Tackling this challenge requires mechanisms that ensure the financial security of farmers while incentivizing private biosecurity efforts to prevent future outbreaks.This study explored crop producers’ preferences for a subsidized insurance scheme as an instrument to manage novel biotic risks.Specific ally,we developed a choice experiment to evaluate Spanish growers’ willingness to pay for a crop insurance product that promotes compliance with best biosecurity management practices.Our results show that while growers are willing to pay more for high coverage products that increase the resilience of crops to potential catastrophic outbreaks,there is neither a strong demand nor widespread availability of such tools.Farmers required reductions in premiums before undertaking risk prevention measures;they are more willing to pay for schemes that link their eligibility to access to ad hoc funds in the eventuality of a catastrophic outbreak than they are to purchase insurance.Our findings also suggest that Spanish growers prefer expanding the eligible risks covered by insurance and envisage a role for insurance in offering biosecurity protection.

Tree diversity and nectar composition affect arthropod visitors on extrafloral nectaries in a diversity experiment

Journal of Plant Ecology 2017年第1期10卷 201-212页

Aims Plants with extrafloral nectaries(EFNs)are common in tropical and subtropical habitats and,despite many other arthropods also forage for EFN,most studies solely focused on the defense mutualisms between EFN plants and ants.This study aims at a quantitative assessment of the entire arthropod community that visits EFN trees to compare visitor communities between different tree species to disentangle the mechanisms that may drive EFN visitor community composition.We also test for tree diversity effects on EFN visitors,as it is unknown if local tree species richness relates to the abundance and species richness of arthropods foraging for EFN.Methods We sampled EFN-visiting arthropods in the experimental tree species richness gradient of the BEF-China experiment,the currently largest forest diversity experiment in the world,and tested if tree species richness affects EFN visitors and if visitor community composition differs between EFN tree species.In a second step,we analyzed the EFN of Ailanthus altissima and Triadica cochinchinensis,the two EFN tree species with highest visitor abundance,for sugars and amino acids(AA)to test if tree species-specific differences in nectar chemistry translate to differing visitor communities.Lastly,we conducted a choice experiment using different artificial nectar solutions to test if nectar quality affects foraging decisions of ants,the most frequent EFN visitors in our study sites.Important Findings EFN trees in young successional forests in subtropical South-East China are visited by a diverse assemblage of arthropods including ants,beetles,flies,and spiders.Albeit ants accounted for about 75%of all individuals,non-ant visitors were by far more species rich.Visitor abundance and species richness declined with increasing tree species richness,suggesting a resource dilution effect,because plots with more tree species had proportionally less EFN tree individuals and thus lower nectar availability.Ailanthus altissima and T.cochinchinensis were visited by different arthropods and

A Comparison of Value Elicitation Question Formats in Multiple-Good Contingent Valuation

This paper provides a convergent validity test of two types of multinomial choice questions vis-a-vis a dichotomous choice question by formally testing whether these stated preference elicitation question formats provide comparable welfare estimates. In particular, a dichotomous choice question, a traditional multinomial choice question, and a modified multinomial choice question suggested by Carson and Groves （2007） were applied in split samples to assess the influence of the informational and incentive properties on the respondents＇ annual willingness to accept compensation for adopting costly conservation practices in agriculture that benefit the environment. Our findings suggest that the two multinomial choice question formats elicit a similar mean willingness to accept distributions, but they are both different from a standarddichotomous choice question. Further, the willingness to accept distributions derived from the multinomial choice question formats are more dispersed than those from the dichotomous choice question.

Despite the number of studies focusing on the financial analysis of production activities, conducting on technical solutions, and improving water quality, no study has been conducted on the application of economic instruments that apply to water quality management in craft villages, and several studies of WTP also. This study aimed to estimate the households’ willingness-to-pay for wastewater treatment in selected traditional agro-food processing villages in Nhue-Day River Basin, Vietnam. A pilot choice experiment (CE) technique in choice Modelling (CM) approach was applied for this study with 267 selected agro-food processing households by using the conditional logit (CL) and random parameter logit (RPL) models. The results showed that total annual environmental fee for wastewater treatment from agro-food processing households is estimated as 1089 million VND (equal to US$47,868 per year) for the total of 902 agro-food processing households in three research sites in Nhue-Day River Basin. This estimated budget for wastewater treatment accounted for 55.85% of total annual operation and maintenance costs only. In addition, the technology is improved to enable 90% of treated wastewater. Overall, the results of this study suggest the new wastewater treatment plant construction and improved wastewater collection system by increasing the investment in order to improve the water quality in Nhue-Day River Basin that brings about the reducing environmental degradation, biodiversity loss and human health risks.

鉴于传统旅游承载力以游客数量作为承载对象可能存在的不足和缺陷，提出以环境状态作为承载对象的旅游承载力定义。在评价方法上，在可接受变化限度理论框架下，运用陈述性偏好方法，根据游客在游憩活动中的成本效益作为环境状态可接受程度的评价标准。通过选择试验和条件logit模型得出潜在环境状态下游客对环境质量变化的边际效用和敏感程度。研究结果表明，游客对“拥挤程度”最为敏感，其次是“人文景观的保护程度”，而“植被覆盖率”对游客效用的影响较弱。另外，给出了25个潜在环境属性集的环境状态情况，包括承载力状态，最优与最差状态，以及可接受与不可接受状态。
