Estimating the non-market monetary values of urban amenities has become commonplace in urban planning research, particularly following Rosen’s seminal article on hedonic theory in 1974. As a revealed preference method, the hedonic approach decouples the market price of a house into price components that are attributable to housing characteristics. Despite the potential contribution of this theory in a planning context, three main limitations exist in the conventional applications: (1) variable measurement issues, (2) model misspecification, and (3) the problematic common use of global regression. These flaws problematically skew our understanding of the urban structure and spatial distribution of amenities, leading to misinformed policy interventions and poor amenity planning decisions. In this article, we propose a coherent conceptual framework that addresses measurement, specification, and scale challenges to generate consistent economic estimates of local amenities. Finally, we argue that, by paying greater attention to the spatial equity of amenity values, governments can provide greater equality of opportunities in cities.

Important Challenge

An important challenge of integrated water resources management (IWRM) is to balance water allocation between different users. While economically and/or politically powerful users have well developed methods for quantifying and justifying their water needs, this is not the case for ecosystems—the silent water user. A promising way of placing aquatic ecosystems on the water agenda is by economic valuation of services sustained by ecosystems. In developing countries, the livelihoods of rural people often depend directly on the provision of aquatic ecosystem services. In such situations, economic valuation of ecosystem services becomes particularly challenging. This paper reviews recent literature on economic valuation of aquatic ecosystem services in developing countries. “Market price” is the most widespread method used for valuating marketed ecosystem services in developing countries. “Cost based” and “revealed preference” methods are frequently used when ecosystem services are non-marketed. A review of 27 existing valuation studies reveals a considerable range of estimated total economic value of aquatic ecosystem services in developing countries, that is from US$30 to 3,000/ha/year. The paper concludes that economic valuation is vital for bringing ecosystems to decision-making agendas in developing countries and that great effort must be made to bridge the gap between scientists and decision makers.

PurposeThe paper aims to explore consumer preferences for novel and other quality attributes in processed foods. It focuses on preferences for product origin, certification on food quality and standards and tradeoffs between novelty (fortification and highly processed) and other quality attributes.Design/methodology/approachIn total, 317 consumers were randomly selected at a high-end supermarket and a traditional local market in Dar es Salaam, Tanzania. Stated and revealed preference approaches were used to investigate their preferences for different attributes in processed foods. A hypothetical choice experiment was used to assess consumer preference for six baby food attributes and the tradeoffs between the attributes, while the revealed preference method included questions on consumer's actual processed food purchasing and consumption habits. In addition, consumers were asked a series of hierarchical questions assessing the motivation underpinning their choices for different products attributes.FindingsWhen making choices for processed food attributes, consumers are reluctant to choose novel technologies and have a strong preference for natural, nutritious, tasty and quality processed food attributes. However, they are willing to forego their preference for naturalness and to overcome their reluctance to trying novel technologies when the novelty is embedded with such quality benefits as nutrition, but not so when the embedded benefit is convenience. They are also willing to trade off their preference for nutrition for a sensory taste. This suggests that micronutrient deficiencies can be reduced among women and children under five by employing the appropriate strategies in processed food formulation. Further, the preference for product origin highlights the opportunity for national brands to fill the gap created by the increasing demand for processed foods in Tanzania.Research limitations/implicationsThe study claims a developing country perspective but is only representing consumers in one city in a developing country. However, this study speculates that consumers with representative characteristics in such context are likely to behave the same. Furthermore, although this study controlled for a hypothetical bias, having a hypothetical choice experiment with non-shoppers (non-purchasers) could have triggered the hypothetical bias, making participants concentrate more on non-price than price attributes.Originality/valueThe paper offers a developing country perspective on consumers' preferences for novelty in processed foods and tradeoffs with other quality attributes.

Abstract: The objective of this paper is to develop arguments that compare the dynamics of financial capital and urban space. It is first argued that financial services follow a concentration-centralization logic, with highly specialized services being offered at central places in urban space, and less complex services with a more dispersed pattern. This characteristic simultaneously promotes a centralized-deconcentration effect on the urban structure: the dispersal of services and urban amenities reduces transport costs and improves urban balance in a few places, while complex services are usually highly centralized, therefore promoting unbalanced (centre-periphery) urban development. In order to understand the balance between these two effects, this paper proposes a preliminary investigation that examines the localization of banks, income and other socioeconomic features in the metropolitan area of Belo Horizonte, in Brazil.

Cooked Rice

Abstract Background Rice is one of the few cereals consumed as a whole grain, and therefore the appearance of the final milled product, both before and after cooking, strongly influences the consumer’s perception of product quality. Matching consumer preference for rice grain quality is a key component of rice variety development programs, as the quality drives demand, which in turn drives variety adoption, market price, and profitability. The quality of cooked rice is normally evaluated indirectly, through measurement of key elements driving quality as well as more directly by sensory evaluation, but remains a complex trait conditioned by the genetic complexity of factors driving quality, changes wrought by environment, and the complexity of consumer preferences. Result In this study, we evaluated 17 traits, including the taste value obtained by glossiness of cooked rice (TV), to explain rice eating quality by statistical methods and identified QTLs associated with TV. To explain the correlation among traits, exploratory factor analysis was performed for 2 years. The overall eating quality (OE) was correlated with TV and protein content loading at the same factor (PA1) in 2017, and there was a relationship between the OE (PA1) and the TV (PA2) in 2018 (PA1:PA2, r = 0.3). In QTL analysis using 174 RILs, three QTLs for TV derived from Wandoaengmi6 were detected on chromosomes 4, 6, and 9. The QTL qTV9 delimited within Id9007180 and 9,851,330 on chromosome 9 was detected in both years, explaining approximately 17% of the variation, on average. Through the use of fine mapping, qTV9 was delimited to an approximately 34-Kbp segment flanked by the DNA markers CTV9_9 and CTV9_13, and nine ORFs were listed in the target region as candidate genes associated with TV. In the evaluation of qTV9’s effect on OE, the lines with qTV9 showed a significant increase in correlation coefficiency compared to the negative lines. These data will apply to functional analysis on the glossiness and the MAS breeding program to improve the eating quality of japonica as a donor line. Conclusion In this paper we report a number of QTL associated with changes in glossiness of cooked rice, and these may have utility in the development of MAS in breeding programs with a specific focus on cooked grain quality.

Hybrid Methodology

The concept of multi-sensory perception of cities is one of the elements shaping the complete image of the city. It is an aspect as important to the recipient as the urban structure. The study of the multisensory record of public spaces gives a better chance to understand: the identity of the place, the changing dimensions of cultural heritage, local social problems, and even conditions influencing spatial decisions. Multisensory research has an implementation value and can be an important, previously unaccounted for factor, influencing the revitalization program and planning decisions. Therefore, it is so important to analyze the available literature on the subject, conduct scientific observation of the research area, create a proposal for a hybrid research methodology on multi-sensory recording of space and determine their relationship with activities in the field of urban planning. The trial area – selected public spaces of the Praga – Północ district in Warsaw was adopted according to predetermined criteria, the most important of which were: authentic urban tissue, downtown area, architectural and functional diversity of buildings.

AbstractThis paper examines Chinese consumer preference for major animal products and assesses the potential impacts of a reduction in China's import tariff on its pork and poultry demand and net import. Our analysis suggests that China's demand for animal products will continue to grow as income increases. Using a trade model, results of our scenario analysis indicate that a reduction in China's import tariffs will significantly increase its net pork and poultry imports and the U.S. will capture most of the increases. Nevertheless, the impact on the market price in China and the U.S. is likely to be very small.

Farmers’ acceptance of and preference for crop varieties depend to a large extent on consumption value and market price. Therefore, food quality considerations are crucial for extension of high-yield varieties. We explored whether several new sorghum of varieties that have been found to have high agronomic performance are acceptable for consumption by using them in two foods commonly prepared from sorghum (kamu and tango). All the improved varieties made acceptable kamu and tango. They met the expectations of consumers for colour, appearance, flavour, taste, and texture and did nor pose obvious processing and milling problems. There is a need to monitor these varieties and subject them to further consumer preference tests using quantitative techniques and the combined effects of the major factors that commonly affect acceptance of crops for production and use, namely, expected yield or income, labour requirement, technical feasibility, nutritional value, and acceptability to consumers.

Housing Preferences

The concept of residential housing preferences has been studied across multiple disciplines, with extensive literature supporting both stated and revealed preference methods. This study argues that both preference types, stated and revealed, should be assessed concurrently to achieve a more comprehensive understanding of residential housing choices. To provide evidence, this research used findings from a public participation GIS survey that identified the stated housing preferences associated with three categories of urban residents, which were called urban “tribes”. We implemented an analytical framework using fuzzy modelling to relate stated preferences with revealed preferences for the same individuals using empirical data describing the urban structure in Tampere, Finland. Following an analysis of the relationships between residents’ revealed preferences and urban structural variables, we examined the consistency of stated housing preferences with revealed preferences. The results show considerable mismatch between the stated and revealed preferences for the urban tribes that were examined i.e., the preferred housing environment was significantly different from the actual living environment. Further, the stated preferences showed disequilibrium within the current structure of the housing supply in Tampere. The findings can have important implications for housing policy making in Tampere. Further, the use of a novel fuzzy model approach demonstrated a flexible and tolerant method for working with imprecise and variable social data to capture subtle differences. Finally, this study elaborately discusses the remaining limitations and suggests how they should be addressed in future research.

Sorghum Grain

Sorghum is grown the world over for both human and animal consumption. Recently, the increase in grain production has slowed; simultaneously, its marketability has declined. Grain size is one of the most important determinants of grain yield and market price in India. One important factor responsible for the decline in consumption of sorghum in India is the inferior quality of rainy season produce. Consumers prefer post rainy season sorghums as the grains are bold, round and lustrous in appearance. Any improvement in the quality of rainy season sorghum grain would help it to fetch higher market prices.In the present study, the genetics of important grain quality characteristics such as grain size, grain shape and lustre were studied using two crosses based on elite sorghum lines 463B and AKMS 14B, and a germplasm line, IS 17600, during 2001 at the National Research Centre for Sorghum, Hyderabad, India. Generation mean analysis and frequency distribution studies revealed that grain size is governed by dominant genes that are polygenic in nature. Predominance of dominance and epistatic interactions in both crosses indicates that selection for higher grain size would be more effective if the dominance and epistatic effects are first reduced by a few generations of selfing. Biparental mating is suggested for developing homozygous bold grain lines. Round grain shape is governed by a single dominant gene and grain lustre by two complementary recessive genes. The study suggested that developing a sorghum hybrid with bold, round grain is feasible provided either of the parents has bold and/or round grain. However, for the hybrid to be lustrous, both parents need to be lustrous and homozygous for the alleles conferring grain lustre at a common locus. With the possibility of development of sorghum hybrids with bold, round and lustrous grain, there is scope for improvement in consumer preference of rainy season sorghum grain.
