The small tea growers (STGs) constitute a significant part of the tea industries in several tea producing countries in the world. STGs constitute 70 percent of the tea cultivation by area and 60 percent of the total tea production by volume. However, low profitability, limited marketing options, inefficient supply chain, and dependency on the large tea estates for processing has emerged as a serious threat to the sustainability of the STGs. Mostly, the STG’s role in the tea supply chain is confined merely to the cultivation of the tea leaves. In India too, the STGs are confronted with similar challenges. India is the second-largest tea producer in the world with about 50 percent of the total tea production coming from the STGs. Notably, considering the economic and environmental benefits, some of the STGs have taken to organic cultivation of tea. Further, some of them who adopted organic cultivation also took to processing and marketing of made tea like hand-made green tea, black tea, and other specialty products by themselves. This study seeks to understand and analyze the role of organic cultivation in providing market linkages and the development of value chain(s) for the STGs. The study was conducted in the state of Assam, which is recognized worldwide for the presence of one of the oldest and the largest tea industries. It used a qualitative value chain approach to analyze the current situation of the STGs involved in the production of organic tea. The study mostly relied on primary data collected from the various actors of the emerging tea value chain through a semi-structured interview schedule, in-depth interviews, and focused group discussions. The processing and marketing of tea by the organic STGs in Assam has indeed led to the development of tea value chain(s) for the STGs. Adoption of sustainable agriculture systems like organic cultivation has opened up new opportunities for the STGs to earn from tea processing and marketing by themselves. Although such developments are in a very initial stage, understandings from the present scenario add to the literature on the development of value chain and market linkages for the smallholders in the tea sector with implications for other agricultural sectors as well. Encouraging the STGs to produce orthodox tea products, especially green and black tea varieties, in larger quantity by mobilizing them for collective actions is likely to locate them in the global tea value chain. The study suggests such suitable policy measures to bring about transformations in the tea sub-sector. Appropriate institutional changes to develop sustainable tea value chain(s) controlled by the STGs would be the key to impart overall sustainability to the industry. Such developments are likely to help the tea industry in Assam and other tea producing regions to meet the changing consumer aspirations and sustain global competition.

On the one hand, organic food consumption has emerged as a rapidly growing consumption trend, juxtaposed against the unsustainability of industrialized food provisions. On the other hand, recent reports highlight that premium food consumption is one of the fastest growing luxury market segments worldwide. This paper draws on the theory of social practices in order investigate how organic food consumption can be understood as an emerging luxury fashion trend, comprised of multiple interrelated ‘nexuses of doings and sayings’ that represent the elements of, and situated within the broader context of consumer culture. In this endeavour, we have conducted a situated investigation of organic food consumption in South Korea. Our findings illustrate that Korean consumers engage in organic food consumption not merely for their superior health benefits or sustainability concerns. Instead, organic consumption conveys three distinct consumption value types – namely, functional (e.g., superior quality), experiential (e.g., feeling better about themselves because they purchase eco-friendly produce), and symbolic (e.g., allows them to convey their social status). Importantly, when these value types are taken together, they closely resemble the value derived from luxury fashion, which lead us to the conclusion that organic food consumption can be conceived as a particular type of luxury fashion trend. The paper concludes with the discussion of theoretical contributions and managerial implications.

With the popularization of the issues of global warming and climate change, more and more people are aware of environmental damages caused by human behavior. The fundamental living necessities of humans, such as food, water, clothing, housing and transportation, all take place on the Earth. Many environmentalists and governments worldwide have started to promote low carbon and green concepts. Such a green urgency is sweeping the world. Based on the surveys conducted by the Organic Trade Association (OTA) in 2013, over 40% of those surveyed in US households have a higher level of motivation to purchase organic products, for the sake of their own and their family's health. In addition, 97% of organic product buyers had purchased organic fruits or vegetables in the past six months. We can also see this kind of situation in Taiwan, where about 80% of consumers are willing to pay more money to purchase environmentally friendly products. The OTA even maintains that, except for Japan, Taiwan is the fastest growing organic market in Asia. Therefore, this study aims to explore the consumers' purchase behaviour behind the organic market in Taiwan. The organic market in Taiwan covers the products from agriculture, food processing, textiles, apparels, and even personal care products and cleaning supplies. Following this green trend that seeks to enhance human health and to maintain a sustainable earth to live on, organic stores in Taiwan have become an emerging industry and there seem to be endless business opportunities in this potential organic market. In order to acquire a significant market share, it is necessary for enterprise managers to understand consumers' perceived value of organic products and how this determinant, perceived value, impact their purchase intention. Perceived value is the overall purchase experience of consumers. It is based on the consumers' comparison between the quality and quantity of products received and paid out, and their objective and subjective consideration of certain factors (Schechter, 1984; Zeithaml, 1988). Perceived value varies with the type of products and services and consumers' personal traits (Zeithaml, 1988). Perceived value is a complicated construct and, therefore, its impact on consumers' purchase intentions toward products cannot be judged from a single dimension only (Bolton & Drew, 1991). Literature on perceived value divides it into utilitarian and hedonic values. Utilitarian value refers to the perceived value acquired by consumers after their purchasing goals have been achieved in the process of consumption. That is to say, utilitarian value is the task- and rationalization-oriented decisions of consumers. On the other hand, hedonic value is affiliated to the individual emotional and irrationality phase of consumers, which usually occur during the process of consumption. Consumers commonly feel pleasant emotions and feelings of motivation and accomplishment, or can even fulfill their desire for escape (Babin & Attaway, 2000; Babin, Darden, & Griffin, 1994; Bae, 2008). Past studies have pointed out that perceived value has a direct impact on the purchase intention (Grewal, Monroe, & Krishnan, 1998). However, in the Value-Attitude-Behavior Model, Homer and Kahle (1988) indicated that perceived value affects consumers' purchase intention through the mediating effect sourced from their attitude. The Theory of Planned Behavior (TPB) has been commonly used to explain a variety of human behaviour (Cunningham and Kwon,2003; Andrews, Silk and Eneli,2010; Kim & Chung, 2011). The TPB mainly focuses on the influence of three behavioural intention dimensions of individuals: attitude, subjective norm and perceived behavioural control. In short, following the fundamental concept of TPB (Ajzen, 1985), this study explored the variables of (1) consumers' attitude towards organic products, (2) the subjective norm, represented by the pressure from family members and close friends, and (3) the perceived behavioural control, presenting perceived ability to control the availability and accessibility of organic products. The ultimate goal of this research is to find out the critical determinants influencing consumers' purchase intentions towards organic products. In order to explore the consumers' possible decisive path from perceived values to purchase intention toward organic products (see figure 1), this study includes the variables utilitarian value and hedonic value as the antecedents, attitude as the mediating factor, and both subjective norm and perceived behavioural control as other influential factors. Figure 1: Conceptual framework and hypotheses This study mainly targeted the consumer behavior toward organic products in the Taipei area of Taiwan. Totally 565 samples were collected. Excluding invalid questionnaires (73 samples), the number of valid questionnaires was 492. The valid response rate was 87%. The SEM is a statistical technique combining both factor analysis and path analysis and is widely used in social and behavioural science studies. Therefore, this study adopted the SEM as the analytical tool to explore the causal relationship among the latent variables discussed above. In sum, this study revealed that the proposed model could well predict consumers’ purchase intentions toward organic products. The empirical research results of this study are summarized as follows. First, the findings of this study confirmed the claims proposed by many scholars that perceived value is a critical determinant affecting the purchase intention of consumers (Zeithaml, 1988). The empirical results of this study show perceived value is an important antecedent driving consumers to purchase organic products in Taiwan. Nevertheless, perceived value is a multi-dimensional construct. As Ryu et al. (2010) suggested in order to explain all consumptive phenomena, we should consider consumers' overall evaluation of utilitarian and hedonic values that are taken into account during their consumption experience. This study found that utilitarian and hedonic values are, indeed, the important driving antecedents for consumers to purchase organic products. Moreover, utilitarian value, compared to hedonic value, has a higher level of impact on the consumers’ purchase intention toward organic products. With regard to the sale of organic products, in addition to the emphasis on the interesting and exciting experience acquired from the purchase or use of organic products, what is more important is that managers can directly emphasize the quality, practical value of organic products, and the contribution that organic products make to people’s health and environmental protection. This not only directly drives consumers to purchase organic products but also further promotes the degree of satisfaction of consumers towards organic products, subsequently increasing the chances for organic products to be purchased. In particular, this study also finds that the main reason for people who never purchase organic products is that they do not yet have a preference toward organic products. For enterprises which want to extend the organic market in Taiwan, this study suggests that managers make consumer to be fond of organic products by driving hedonic and utilitarian value that can be provided by the organic products. Second, the influence of perceived behavioral control and attitude on purchase intention, as mentioned in the TPB in previous studies, was also supported in this study. In other words, when consumers purchase organic products, they have been deeply affected by factors regarding the degree of their knowledge of organic products or the accessibility of the organic products. In that case, the channel strategy and the store coverage of organic products should be very critical in the ever-booming organic products market in Taiwan. Besides, this investigation finds that a certain proportion of consumers do not purchase organic products because they do not understand the organic products, which is also a very important clue for the companies that intend to penetrate the market. They could spread environmental protection knowledge via the advertisements to educate consumers about the benefits (such as protecting the environment, and being good to health, etc.) of the usage of organic products. In that way, the potential consumers could be encouraged to purchase organic products and this will be beneficial for the development of total organic product market.

As economic growth and development of the living standard causes increasing production of organic waste, the desire to take advantage of organic waste to produce energy is also increasing. Organic waste-to-energy can contribute to improving energy independence through domestic energy security as well as improving the environment by reducing the need for landfills. This paper attempts to quantitatively analyze the non-market benefits arising from the organic waste-to-energy policy. To this end, we apply a contingent valuation (CV) that is most widely used to measure the nonmarket benefits. As for the willingness to pay (WTP) elicitation method, we employed the one-and-one-half-bounded dichotomous choice (DC) model, which produces higher statistical efficiency than the single-bounded DC model and yields greater consistency than the double-bounded DC model. In the CV survey result of 1000 Korean households, a total of 586 households (58.6%) revealed zero WTP. This implies that the use of the mixture model to deal with zero WTP responses was a suitable approach in our study. The yearly mean WTP was computed as KRW 3598 for the next ten years per household, which is statistically significant at the 1% level. Expanding the value to the national population gives us KRW 67.3 billion per year and this value demonstrates the non-market benefits of the organic waste-to-energy policy. This quantitative information could be utilized as a significant reference in the implementation of the organic waste-to-energy policy.
