An Investigation into Whether It Is Possible for ‘Fast Fashion’ to Adapt to Meet Social Sustainability Goals","authors":"Shakira Wanduragala","doi":"10.5539/jsd.v17n2p35","DOIUrl":"https://doi.org/10.5539/jsd.v17n2p35","url":null,"abstract":"In the last decade, there have been a number of fatal disasters in garment factories across the world, with many of these factories producing garments for the ‘fast fashion’ industry. With the ‘fast fashion’ industry continuing to grow at an exponential rate, it is important, now more than ever, to understand how garment workers at the heart of this growth can be protected in a socially sustainable way. The motivation of this study is to look into ways of empowering producers of the garments, not just those who wear them. The objective of this research is to understand whether it is possible for ‘fast fashion’ to meet social sustainability goals, or whether the model is inherently unsustainable. To address this question, a systematic literature review was conducted, which maps literature on ‘fast fashion’ and social sustainability. This review looks at the two concepts independently, then draws the literature together to explain the relationship, and outlines approaches that can be taken to ameliorate it. The paper presents an argument for how policymakers, businesses and consumers can play a part in making fast fashion more socially sustainable in the hope of one day being able to empower all. The conclusion of this review is that fast fashion is only capable of exhibiting ‘weak’ sustainability, and that systemic change would be needed across stakeholders to address social sustainability goals effectively.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"45 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139442337","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}

The study's objective enhanced the evaluation of the multiphase flow operations involved in hydrogen generation, and determined the key contributors to the multiphase flow in the production of hydrogen. The methodology of the study also involved the design and simulation of the multiphase flow operations involved in hydrogen production and showed the analysis of the flow properties, including pressure profile, velocity profile, concentration profile, and shear rate profile, thereby insights into the multiphase flow interactions. Additionally, the research results enabled an improved understanding of the multiphase flow interactions in hydrogen production and led to an improvement in the process operational conditions for the system. The inference of the study was based on the quantifiable results obtained from the simulation which provided a comprehensive analysis of the multiphase flow characteristics in hydrogen production. More importantly, the shear stress for water-hydrogen system and hydrogen were shown with the shear rate describing the gradient in velocity and the pressure profile, shear rate profile, and velocity profile were calculated for a 2D profile versus the arc length for each of these variables. Thereafter, the results of this research simulation demonstrated that high velocity profile for hydrogen flow was observed within the reactor; with the highest velocity observed in the reactor within the length of (0.5 – 6.5)m, hence indicating optimum length of the water-split reactor for maximum velocity flow. The results further indicated that the profile of water-hydrogen and hydrogen pressure becomes uniform at a distance of 1mm from the entrance and the maximum pressure flow for water-hydrogen and hydrogen fluids pressure are 17.8Pa and 238.27Pa which shows a sufficiently higher pressure of hydrogen.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"17 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138978795","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}

According to the Abuja declarations in the year 2000 during the formulation of Millenium Development Goals, the parties agreed to increase their healthcare budget to a whopping 15%. By the end of the Millennium Development Goals, partly no country had reached such a target. It is therefore imperative for Countries to make sure their healthcare budget can address the prevailing needs of their citizens. To make sure the set goals are achieved, it is thus incumbent upon the government to set achievable targets. The focus of this research was to ascertain how project planning plays a nexus role in supporting the healthcare system at level two. The major variable was to assess how the project scope affects such an endeavor and how the existing government policy intervenes in such achievements a case of Kenya Health Policy established in 2014 and running till 2030. The research will be guided by an exploratory research design since it will expedite both Quantitative and Qualitative data from a sample size of 100 respondents. Quantitative data was analysed using SPSS version 25 while Qualitative data was analyzed using the content analysis method. The study findings postulated that most projects were completed within budget while others were not. Delay of disbursement of Funds by the Government to the health facilities was picked as another cause of failure to meet the goal, politics was also noted to play a role in such endeavors. With such findings, the study thus recommended the establishment of a framework that supports better collaboration between the primary parties in the government and the health facilities. The study also acknowledges budget, cost, and planning attributes are crucial to the successful implementation of level-two health projects. This study focused on adding value to the existing body of knowledge and practice as enshrined in the Kenya Vision 2030 blueprint and Kenya Health Policy 2014-2030 blueprint.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"57 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138593683","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}

The study aimed to analyze gas exchange in tomato, in full production, in plants cultivated under different water management. The experiment was conducted in a completely randomized design with two water conditions during cultivation (with deficit and without deficit). The management of the water deficit adopted using different depths of water replacement, under water deficit the replacement of 60% of the crop evapotranspiration (ETc) was carried out while in the condition without deficit there was replacement of 100% of the ETc. The determination of gas exchanges, in a period with full production, was performed at 70 and 71 days after transplanting, determining photosynthesis (A), stomatal conductance (Gs), internal CO2 (Ci) and transpiration (E). From the A/E ratio, the intrinsic water use efficiency (iWUE) was calculated. The data were submitted to analysis of variances and the means compared by the Tukey test with 5% of significance. There is significant variation in gas exchange rates depending on the water management adopted and evaluation period. Water deficit has a cumulative effect on plants. Tomato plants cultivated with water deficit (60% of ETc) have lower rates of gas exchange, with no full recovery of rates even after irrigation. Tomato plants grown without water deficit (100% of ETc) show adaptation and compensation in gas exchange due to soil drying.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"42 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138595344","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}

The experiment was conducted using a completely randomized design, with four treatments and eight repetitions. The treatments involved two methods of application: aerial (RPA, 10 L ha-1) and ground (backpack sprayer, 100 L ha-1); and two types of nozzles: the standard flat fan nozzle XR 11001 and the air induction flat fan nozzle AirMix 11001. To study the quality of the application, the deposition was evaluated using a tracer and spectrophotometry, and the droplet spectrum, evaluated through the analysis of water-sensitive paper. Furthermore, a study on application quality was conducted using the Statistical Process Control methodology. The results demonstrated that with RPA, the deposition was higher, and the AirMix 11001 nozzle also stood out in this variable. No non-random behavior was observed in the deposition. Ground application showed the best performance in terms of target coverage and droplet density. The XR 11001 nozzle resulted in a higher droplet density. Overall, the XR11001 nozzle and the RPA application showed smaller volume median diameters (VMDs), indicating a higher potential for drift, which should be taken into account. Given the results obtained, it can be stated that the use of RPAs for agricultural spraying is viable for application.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":" 38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138612278","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}

A categorical regression analysis was conducted on quantitative data that were randomly collected from 308 respondents. The pluralistic agriculture extension service accounted for a 40% and 32% change in social and economic resilience respectively. The main factors that had positive and significant effects on socioeconomic resilience were the management style of extension agents and participatory monitoring and evaluation of smallholder farmer extension activities that caused less than half a unit fold of increment in socioeconomic resilience. Although small, they form the ground for farmers’ capacity to buffer, adapt to changes, and cope with stresses and disturbances. The F-values in the regression models are important in the prioritization of the significant factors during the design and implementation of extension models. The paper contributes to the ongoing discussion on the role the pluralistic agriculture extension system plays in enhancing farmer resilience and the use of quantitative methodological procedures in identifying the strength of the relationship between the factors.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139234249","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}

As such, one of the significant aspects in this context is the residential satisfaction from the residents’ perspective. Having this mind, residential satisfaction among the city dwellers in most urban areas become highly unclear and for Mashhad’s urban areas, there is dearth of knowledge. Therefore, the current study was an endeavor to explore the level of residential satisfaction among the residents in District 11 of Mashhad, Iran and to explore whether residential satisfaction rates differed according to demographic information including gender, job type, age, and residency history. A questionnaire on Residential Satisfaction examining four categories of body, facilities, utilities, and economy using 22 questions, which showed a reliability of 0.81 was completed by 70 participants. The Statistical analyses revealed that residential satisfaction level among the participants of this study was above average and the highest satisfaction rate belonged to the body of the apartment whereas the lowest category went for utilities. Moreover, the residents showed dissatisfaction with parking, followed by garbage collection, and the asphalt in the neighborhood as the biggest concerns; yet, they were highly satisfied with water, electricity, gas, telecommunication and drainage system. As for the demographic data of the residents, it was found that there was no statistically significant difference between males and females in terms of their satisfaction rate, and that no significant difference was found in terms of job type, i.e. governmental or private, while the same results was found concerning the age. Finally, there was no significant difference between residency history and residential satisfaction level.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"38 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139260599","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}

The experimental design was a randomized complete block in a 3x6 factorial arrangement, with three potassium rates (0, 80, and 160 kg ha-1 kg of N) and six corn hybrids (20A55Hx, 30A77PW, AG1051, MG652PW, NS90VTPro2, and NS92VTPro), with three replicates. The data were analyzed through the analysis of canonical variables. Nitrogen doses interfere directly with the tolerance and resistance conferred by the Cry proteins of the plants in corn hybrids, altering the control of the caterpillar Spodoptera frugiperda and possibly favoring the breakdown of resistance in low availability. The corn hybrids showed divergent performance regarding proteins under low nitrogen availability (0 and 80 kg ha-1), and it was impossible to state which would be the most efficient protein. However, pyramiding has greater control under the recommended dose (160 kg ha-1 of N), with damage in the opposite direction to the transgenics.","PeriodicalId":91562,"journal":{"name":"Journal of sustainable development","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135390046","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}
