This study assessed the value chain analysis of large cardamom (Amomum subulatum Roxb) in Taplejung district, Nepal and explored the functional linkage and upgrading strategies among the key value chain actors. One hundred and sixty farmers were surveyed purposely along with 5 local and district level traders, 5 regional level traders and exporters and 5 enablers who were sampled using rapid market appraisal in March 2018. The study presents a comparative analysis among large holders (n=72) and smallholders (n=88) large cardamom farmers using SPSS and MS-Excel. The majority of farmers used suckers as propagating materials which was a major source of disease conduction. 62.5% of farmers adopted traditional dryers for curing, which reduced the quality of large cardamom whereas about 30% of them used improved dryers for curing that enhanced quality. The majority of farmers had not adopted value addition practices like tail cutting, grading and packaging which were carried out at trader level. Large cardamom prices were normally determined by the export market of India. The average land area of large cardamom per household was 21.56 ropani with 36.74 ropani for the large landholder farmers and 9.14 ropani for the smallholders. The key problems faced by farmers and traders were high price swing, lack of disease-free propagating materials, reliance on the Indian market, aged orchards, shrinking productivity, and minimal collaboration among the chain actors. Therefore, adoption of Good Management Practices (GMPs)- upgraded bhattis, transfer of tail cutting technology and storage management, along with value addition activities like grading (color and size), tail cutting and packaging need to be adopted with strong adherence to export quality. This study revealed that necessary action needs to be taken to maintain a high level of collaboration among the value chain actors thereby increasing the value chain efficiency of Nepalese large cardamom.

There is a widespread consensus that energy efficiency of buildings is an essential component of sustainable development and several kinds of renewable energy technologies have been widely used to achieve this sustainable goal. As a rapidly developing country, China’s manufacturing industry still occupies a prominent position, with a large number of industrial buildings that are also a crucial part of urban planning. Compared with multi-story and high-rise commercial buildings, large industrial sheds have a much more usable roof area, where rooftop photovoltaic (PV) systems are increasingly used. However, due to the small structural margins of the lightweight steel-structured (LSS) industrial buildings and the large initial investment of the thin-film PV system, few case studies are available for this kind of industrial buildings. In this research, three representative cities in China, with varying levels of solar radiation availability, are selected as typical external design factors. Taking a typical LSS industrial building with an added thin-film rooftop PV system as an example, a life-cycle cost-benefit analysis is conducted from environmental and economic aspects. The results of the analysis demonstrate the effectiveness of the rooftop thin-film PV system as a means to increase the energy efficiency of the LSS industrial buildings.

Despite the growing interest in sustainability, negative associations of this term with naïve discourses, green-washing, or low-quality design are still common within some areas in the discipline of architecture. Through a literature review and an examination of the programs of the top ten architecture schools, this article explores the causes and implications of this slight but persistent discredit of sustainability in the field of architecture. The article discusses how some of the perceived downsides of sustainability are reflected on the university curricula, as the fragmented understanding of environmental problems or the overly technical approach to their solution within technology and design. The discussion also addresses the improvements brought by recent multidisciplinary explorations of environmental issues made within the architectural humanities, that provide students a comprehensive historical, social, and cultural understanding of the issue.

In recent years, the growing awareness of the possibilities of biomimetic and adaptive materials in architecture has assumed a fundamental importance in the scientific domain, for the high performance of the building façades from an environmental point of view. To meet the housing and comfort needs in climates, such as the ones in the Mediterranean zones, characterized by ever-increasing temperatures, architectural technology must collaborate with nature in an even more decisive way, through increasingly smart and sustainable solutions. The paper reviews a collection of good practice examples of advances in material science, and the method used is to analyze the current performance of and building envelopes with smart façade skins, in order to suggest some potential applications in the Mediterranean basin and regions of the world with similar climatic characteristics. The latter case studies, especially, show built examples of adaptive buildings that could be adopted for use in Mediterranean regions. When the climate characteristics are somehow different, the good practices from elsewhere can be implemented in an innovative way.

Water begets intricate and profound linkages between multiple systems. Quantitative limits to freshwater availability for human needs, variabilities in the water cycle and environmental water requirements interact with water source pollution. The arising tensions are a great challenge of immense contemporary significance that can best be described as a wicked problem – a problem with multiple dimensions that presents unexpected consequences when engaged. Water challenges make vivid the compromises that must be made between the environment and development. These compromises surface in the conflict between ecocentric and technocentric discourse. Globally, there is evidence of numerous disciplinary and interdisciplinary water-related studies both in the past and ongoing. But there is no meta-mapping of various dimensions of such research to give a clear overview of what has been and what needs to be done. Consequences of this oversight may include unnecessary duplication of research, difficulty in articulating knowledge gaps, and inability to see beyond disciplinary boundaries. The author suggests an outline of how these difficulties can be engaged. This is done through a wide-ranging literature review to identify a range of issues of focus, which issues are then themed into imperatives for water research. These imperatives are subsequently systematised using four normative descriptors: problem, drivers, and mitigation measures. In combination, these descriptors articulate a spectrum of the key issues around water research. The key issues are mapped onto various academic disciplines and societal partners to outline a schema for the positioning of water research. The proposed mapping can facilitate interdisciplinary and transdisciplinary (IDTD) research by allowing researchers to benefit from relevant existing bodies of knowledge while also making explicit knowledge gaps and opportunities for collaboration. By locating academic fields within different worldviews, the outlined schema reveals common ground beyond disciplinary confines around which IDTD research can be instigated.
