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.","PeriodicalId":137433,"journal":{"name":"International Journal of Environmental Science & Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116233055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":137433,"journal":{"name":"International Journal of Environmental Science & Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132874091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Public squares and streets became important places of interaction. ‘Historic core,’ especially had public spaces meant for various socioeconomic groups. city is a blend of a harmonious past and a vivacious present. Number of historical and architecturally important buildings were built during Muslim and Moghul rules. One of the first built structures within the walled city is the fort, a citadel founded by sultan Ahmed Shah in 1411 with a huge public square in front, developed for purpose of procession and gathering. This precinct went through various layers of transformation in different eras and now have become vulnerabledue to congestion and encroachment. Though, a need for intervention was felt to bring back the lost vitality of the precinct, it was realized that a comprehensive approach would be the necessity. Conservation and sensitive development approach was taken to tackle this problem through pedestrianization of the precinct, re-routing of traffic and restoration of fort. Larger level traffic and parking issues were also considered beyond the site. Alternative use of fort as tourist information center was considered. Urban design guidelines were proposed for harmonious development in the surrounding area. This proposal was considered for funding under Jawaharlal Nehru National Urban Renewal Mission (JnNURM) and was implemented. Many issues were faced during implementation of project due to contextualization of informal commercial, religious and other cultural activities. Political, social and administrative factors also played immense role in implementation of proposal. Now since Ahmedabad has achieved the status of World Heritage City through UNESCO certification further implementation of this project will be relatively easy due to envisaged strong political and administrative support.","PeriodicalId":137433,"journal":{"name":"International Journal of Environmental Science & Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131185261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such an urban context there is a need for an efficient tool that contributes positively to the enhancement of the QUL, meanwhile to provide the best use of the rare vacant lands.This study argues that urban architecture as a design field offers a distinctive approach to a special type of buildings made for an urban setting, thus it can enhance the QUL in UPA through community projects.The study is based on an analytical study of selected cases of community projects in UPA that represents examples of how urban architecture through its potentials has a positive impact on its urban context, notably through community projects that strongly linked to real community needs.

Can innovation affect the improvement of the quality of life inside urban areas? This research question comes from the consideration that usually innovation and growth in general are considered sources of conflict in affecting the livability of large cities. The objective of the paper is to design a model — the “SustaIn-Led” - to connect levels of environmental sustainability, quality of life, and economic development inside metropolitan areas, taking into account also innovation processes, activated by the innovation policies and by the knowledge economy. The study takes in consideration the 53 largest United States metropolitan areas with a population over 1 million, with a time series from the years 2000 through 2015. This has been done because of a two-fold reason: (1) the US among high-income countries is the one with the highest number of universities, patents, and citations; (2) several studies have shown that innovation occurs in large cities. The first part of the present study has carried out the identification of the variables to represent and significantly explain the phenomena – local economic development, innovation, and environmental sustainability – linked to the design of the SustaIn-LED model. Environmental sustainability in urban areas in this paper is represented by means of the Air Quality Index (AQI), while the number of workers synthetically quantifies local economic development. Correlation and multiple regression analyses are conducted in order to examine the relationship between the three main indicators. The multiple regressions for the year 2015 produced a low p-value, indicating that the predictors are significant in the regression analysis. Similar results of p-value are shown in all the years from 2000 to 2013. For 2015, the results showed that part of the variance in the measure of total workers of the metropolitan areas could be predicted by measures of innovation and air quality. Higher R² values have been registered for the years from 2000 through 2013. The development of the SustaIn-LED model could be utilized in urban regeneration processes to help in the design of new urban planning policies inside large cities by means of a better comprehension of environmental and economic implications caused by the implementation of innovation policies.","PeriodicalId":137433,"journal":{"name":"International Journal of Environmental Science & Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122483624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
