The corn is a traditional food in Mexico that has been influenced by the current dynamics of the markets, causing the replacement of creole varieties by improved varieties and hybrids. Foods are characterized by a set of attributes that can be associated with a subjective evaluation, from which it is possible to approximate a utility function and determine elements for its evaluation. The objective of this work was to evaluate the Mexican consumer's willingness to pay for various types of corn and to determine which of them have a higher valuation. The methodology was based on a contingent valuation study, with a total of 356 consumers selected by snowball sampling (95% reliability and 7% error) and answering a questionnaire designed in Google forms, addressing consumer sociodemographic information, characteristics corn and their willingness to pay. The willingness to pay extra for corn was significantly influenced when the consumer determined that it is important to know if the corn comes from Creole or modified seed and if it has any certification. Creole and imported corn obtained a greater willingness to pay, giving higher valuation to these products. In conclusion, the present work explores the economic valuation of corn, where significant factors can be used to induce an effect on consumers, particularly in the revaluation of creole corn.

Abstract. Melak A, Belayhun T, Kefyalew E, Hailu A, Mustefa A, Assefa A. 2020. Farmers' willingness to pay for Sinar donkey conservation in selected districts of Metekel and Assosa zones, northwest Ethiopia: a contingent valuation study. Biodiversitas 21: 3373-3379. A survey was conducted through single field visits and interviews with 160 respondents in selected districts of Assosa and Metekel Zones, Northwestern Ethiopia, to elicit farmers' willingness to pay for Sinar donkey conservation. Two districts namely Guba and Sherkole were purposively selected from the zones based on the availability of Sinar donkey breeds. Eight representative kebeles were selected from the two districts. A total of 160 households (each district 80 households) were selected randomly. Structured and semi-structured questionnaires were prepared to collect data on socio-economic and farming system characteristics. Descriptive statistics were employed to summarize data and average means were compared using SPSS version 23.0 software. Logistic regression was applied to see the effect of independent variables on the dependent variable. The contingent valuation method was used to know farmers' willingness to pay for conservation of the Sinar donkey breed. The average willingness to pay for the conservation was 98.25 Ethiopian Birr or 3.265US dollars for the conservation program per household per annum. The cash income of the respondents influenced the willingness to pay for the conservation program. This study supports the view that the economic valuation of donkey genetic resources can assist policymakers in setting conservation priorities.

Environmentally Sound

Management of Waste Electric and Electronic Equipment (WEEE also called e-waste) has become an issue of critical importance recently also in the frame of industrial ecology besides waste management per se, mostly due to their content in hazardous materials and the extensive implications of any intervention in a broad industrial spectrum. The effectiveness of any landfill diversion scheme depends on its acceptance by the local community and the industry, as well as adequate funding. This paper presents a contingent valuation approach in order to examine public environmental awareness and to assess the willingness-to-pay (WTP) for the environmentally sound management of WEEE in Greece, based on a suitable, customized and easy-to-comprehend questionnaire. The survey revealed a still relative public ignorance on the subject and a reluctantly limited WTP. The latter is mostly triggered by the fact that respondents believed that associated expenses should be covered either by authorities or manufacturers (protest votes). However, based on the responses of those declaring a positive WTP, the average fee respondents are willing to pay exceeds the current recycling fee. Thus, existing recycling fees could be potentially increased in order to cover additional expenses for the development of infrastructure in areas not currently included in the national WEEE recycling program, as well as to provide the public with a dense network of disposal sites/bins in an effort to boost participation and WEEE recycling rates.

Soil contamination caused by economic growth through industrialization and urbanization has been progressed inKorea. Soil polluted with heavy metals and chemicals makes significantly negative effects on human and wildlife health. This paper attempts to measure the economic benefits from the contaminated soil remediation policy using a specific case study ofKorea. To this end, the contingent valuation (CV) method is employed. A CV national survey of randomly selected 500 households was implemented using person-to-person interviewing in May 2105.  To elicit the willingness to pay (WTP), we apply one-and-one-half bound dichotomous choice question format to reduce the potential for response bias and spike model to deal with zero willingness to pay (WTP). The mean WTP for the policy is estimated to be KRW 1,357 (USD 1.2) for next ten years per household per year and statistically significant at the 1% level. Expanding the value to the national population gives us KRW 25.4 billion (USD 22.9 million) per year. We can judge that the Korean public places a significant value and be utilized in assessing the total benefits from the policy.
