Recent soundscape research is notable owing to the increasing demand for “multisensory” tourism experiences. However, the traditional economic value assessment of tourism destinations mostly takes each type of landscape as a whole for measurement, and it has been challenging to separate the soundscape from the whole landscape. Therefore, research on the economic value of soundscapes is still lacking. This study chose the characteristic soundscape of the Qiantang River tide as the research object, and tried to apply the pairwise comparison method to calculate the separation coefficient of the soundscape from the overall landscape. The results showed that the separation coefficient of the soundscape was 0.138 and the economic value of the Qiantang River tide soundscape was between CNY 315.145 million (USD 48.7 million) and CNY 333.841 million CNY (USD 51.6 million). Finally, we discuss the effectiveness of the separation methods, the differences in willingness to pay between the interviewees, and the sustainable use of the natural soundscape resources in tourism destinations.

Abstract Garbage or waste is basically a residual material resulting from human activities and natural processes that have no economic value anymore. The volume of waste in Malang City and Malang Regency every year always increases, so the existing waste final processing site will no longer be able to accommodate the pile of garbage. Therefore the Malang City Government plans to collaborate with the Malang Regency Government in making an integrated regional waste landfill and processing site. In this study, an analysis of the determination of the appropriate location for regional waste final processing for Malang City and Malang Regency was carried out using the Simple Additive Weighting (SAW) method. The SAW method is a weighted summation method, which can make a more precise assessment, based on the predetermined criteria and preference weights. Preference weights were determined by pairwise comparison method. The criteria used are geological hazardous areas, distance from drinking water sources, land slope level, distance from settlements, protected areas and distance from airports. The final result in this study is a map of the appropriate location for a regional waste final processing site and an analysis of the location for the best regional final processing site. The location map is classified into three, namely: not feasible with a total area of 54,774.33 ha, less feasible with a total area of 170,846.49 ha and feasible with a total area of 130,096.63 ha.

In light of the increased importance of sustainability issues in the world economy, this study calculates the economic value of the swampy wetlands in Ghana’s Northern and Ashanti region, based on rice farmers’ and community members’ willingness to pay (WTP) for the sustainable use of the wetlands. It also examines the factors influencing this WTP. Data from 160 rice farmers and community members in four districts were collected via a questionnaire survey. A logistic regression model was employed to determine the significance of the influencing factors, while the respondents’ WTP was estimated by the contingent valuation method. The results revealed that 89.4% of the respondents were willing to contribute about 54.90–213.11 USD/household/ha/year and an aggregated 0.298–1.158 million USD/year to ensure swampy wetland sustainability. On an average, they were willing to pay 180.17 USD/household/ha/year and an aggregated 0.979 million USD/year. Gender, household size, household disposable income, and knowledge of the importance of wetlands were found to be the determinants of WTP. We recommend that farmers and the public be educated on wetland ecosystems and family planning. In addition, reducing household size and providing rice farmers with adequate irrigation and postharvest facilities are worthwhile conservation measures.

Proposed Model

Introduction: Large-scale human-computer systems involving people of various skills and motivation into the information processing process are currently used in a wide spectrum of applications. An acute problem in such systems is assessing the expected quality of each contributor; for example, in order to penalize incompetent or inaccurate ones and to promote diligent ones.Purpose: To develop a method of assessing the expected contributor’s quality in community tagging systems. This method should only use generally unreliable and incomplete information provided by contributors (with ground truth tags unknown).Results:A mathematical model is proposed for community image tagging (including the model of a contributor), along with a method of assessing the expected contributor’s quality. The method is based on comparing tag sets provided by different contributors for the same images, being a modification of pairwise comparison method with preference relation replaced by a special domination characteristic. Expected contributors’ quality is evaluated as a positive eigenvector of a pairwise domination characteristic matrix. Community tagging simulation has confirmed that the proposed method allows you to adequately estimate the expected quality of community tagging system contributors (provided that the contributors' behavior fits the proposed model).Practical relevance: The obtained results can be used in the development of systems based on coordinated efforts of community (primarily, community tagging systems).

Developing understanding of the economic value that communities ascribe to improved operations and maintenance (O&M) services has emerged as a key factor in achieving financial sustainability for rural water systems. The present study elicits household willingness to pay (WTP) for improved O&M services in eight gravity-fed water schemes in Idjwi Island (Democratic Republic of the Congo, DRC). A contingent valuation survey was implemented through an open-ended format questionnaire to 1105 heads of household and a log-linear regression model was employed to assess the factors influencing higher values. Findings show an average willingness to pay of 327 Congolese Francs (CDF) per month and 36 CDF per bucket. Results also indicate a significant WTP differential among studied schemes. The analysis of the conditioning factors reveals that the level of excludability, the participation in management meetings and the time employed in fetching water from an improved source are contingent with their WTP. The findings of this study are important for development agents trying to establish acceptable, affordable and practicable tariffs that help finance reliable rural water systems in Idjwi.

Increased manufacturing activity has an impact on environmental quality degradation. Waste generated from manufacturing activities is one of the causes. Previous studies have referred to this waste as value uncaptured. Minimizing value uncaptured is a solution to improve environmental quality. This study aims to reduce value uncaptured by converting it into value captured. This process requires a value proposition design approach because of its advantages. One of the advantages of this approach is that it can improve existing or future products/services. To do so, this research uses a case study of a furniture company. To implement a converting process, a sustainable business model is proposed to solve this problem. This business model combines several methods: value proposition design, house of value and the product sustainability index matrix. Recently, the existing value proposition problem-solving has been using the value proposition design method. This research proposed implementing a house of value to replace the fitting process. The questionnaire is developed to obtain various value uncaptured in the company. To the weight of the value uncaptured, this research utilized the pairwise comparison method. Then, the weights could represent the importance of jobs. Based on the highest weight of these jobs, the alternative gains would be selected. To provide the weight of the gain creators and value captured, the house of value method is developed. Referring to three pillars of sustainability, the value captured should be considered. This research proposed implementing a product sustainability index which in turn produces eco-friendly products. This study produces “eco-friendly products” as sustainability value captured. The sustainability business model could be an alternative policy to minimize the existence of value uncaptured.

Toxicological Studies

An integrated and interdisciplinary research programme with native medicinal plants from tropical forests has been performed in order to obtain new forest products for sustainable use in regional markets vis-à-vis ecosystem conservation. For the success of this programme ethnopharmacological studies are very important with respect to (i) identification of useful plants including medicinal and aromatic species; (ii) recuperation and preservation of traditional knowledge about native plants; and (iii) identification of potential plants with economic value. The plants are selected with a view to evaluate efficacy and safety (pharmacological and toxicological studies), and phytochemical profile and quality control (phytochemical and chromatographic characterization). These studies are very important to add value to plant products and also to mitigate unscrupulous exploitation of medicinal plants by local communities, since multiple use of plants represents an excellent strategy for sustaining the tropical ecosystem through ex situ and in situ conservation. Thus, conservation of tropical resources is possible in conjunction with improvements in the quality of life of the traditional communities and production of new products with therapeutic, cosmetic and ‘cosmeceutic’ value.

The evaluation of design concepts is a time consuming and resource intensive process. Crowdsourcing evaluations has been examined in previous work as a means to reduce the need for expert raters, while achieving similar evaluation results. This paper examines the impact of empathically priming novice raters on their evaluation of alternative design concepts. The rating system is based on a pairwise comparison method that requires minimal training of novice raters. In a pilot study the pairwise method for crowdsourcing evaluations is compared with crowdsourced evaluations using non-pairwise rating scales and with the evaluations of expert raters. The primary study incorporates written and empathic priming strategies to determine their impact on novice raters’ evaluation of concepts. Raters are asked to consider several criteria, including novelty, feasibility, clarity (of the concept), usefulness, ease of use, and overall worthiness of further development. Results offer insight into the criteria that are most relevant to novice raters and whether empathic priming has a significant effect on those evaluations.

<p>Ecosystem services that are not traded on markets contribute to human wellbeing however their economic value is not well known and research is required to reveal it. This paper reports on a study of willingness to pay (WTP) for the maintenance of Mount Wilhelm by urban residents and socio-economic factors influencing it. The possibility of developing an ecotourism strategy that could generate benefits for local are discussed. The data were obtained from questionnaire and personal interviews of residents of Kundiawa, which is the capital of Simbu Province, Papua New Guinea. The data were analysed using descriptive statistics and binary logit regression model. The results showed that 92% of the respondents were willing to pay for maintenance of Mount Wilhelm and they would pay an average of 7.4 Papua New Guinea Kina (US$ 2.5) each year. The respondents who belonged to high income group had the highest WTP, followed by those who were willing to give out part of their land for conservation. Approximately 62% of the respondents would pay ≥10 Papua New Guinea Kina (PGK), which is equivalent to the amount charged as access fee to Mount Wilhelm by the locals living around it. The willingness to pay ≥10 PGK was influenced by income, education, importance of forests and willingness to give up land for conservation. The findings will contribute to land use planning and design of nature-based recreation that meets societal demands.</p>
