Urban Heat

The increasing population density in urban areas simultaneously impacts the trend of energy consumption in building sectors and the urban heat island (UHI) effects of urban infrastructure. Accordingly, passive design strategies to create sustainable buildings play a major role in addressing these issues, while solar envelopes prove to be a relevant concept that specifically considers the environmental performance aspects of a proposed building given their local contexts. As significant advances have been made over the past decades regarding the development and implementation of computational solar envelopes, this study presents a comprehensive review of solar envelopes while specifically taking into account design parameters, digital tools, and the implementation of case studies in various contextual settings. This extensive review is conducted in several stages. First, an investigation of the scope and procedural steps of the review is conducted to frame the boundary of the topic to be analyzed within the conceptual framework of solar envelopes. Second, comparative analyses between categorized design methods in parallel with a database of design parameters are conducted, followed by an in-depth discussion of the criteria for the digital tools and case studies extracted from the selected references. Third, knowledge gaps are identified, and the future development of solar envelopes is discussed to complete the review. This study ultimately provides an inclusive understanding for designers and architects regarding the progressive methods of the development of solar envelopes during the conceptual design stage.

The Impact

The deposition of air pollutants on glazing can significantly affect the daylight transmittance of building fenestration systems in urban areas. This study presents a simulation analysis of the impact of air pollution and glazing visual transmittance on indoor daylight availability in an open-plan office in London. First, the direct links between glazing visual transmittance and daylighting conditions were developed and assessed. Second, several simple algorithms were established to estimate the loss of daylight availability due to the pollutant deposition at the external surface of vertical glazing. Finally, some conclusions and design strategies to support facade planning at the early design stage of an urban building project were developed.

Global warming and undeniable climatic change in the world have led to decreasing thermal comfort for humans. Urban heat island (UHI) is the most documented phenomenon which has led to the increasing temperature in urban areas. It has received much focus in the past few decades to evaluate the main effective criteria of UHI. Street heat has negative effects on human health and will only worsen in future; these negative effects would double in hot and dry urban area. This paper investigates the effects of UHI in these cities and illustrates the important factors which make them extremely hot. The outcome of this study can be used to determine the key guidelines for urban designers, urban planners, architects and landscape designers to recline the UHI impressions in urban areas and make more thermal comfort for Burgher.

Significant increase in municipal solid waste in Nepal has led to build up of few landfill sites in urban areas. Among several problems existing in the landfill sites, groundwater and soil contamination are the major problems. The major causes of contamination are generation of leachate, improper design and selection of materials in the landfill sites. Therefore, understanding on physical and chemical behavior of the leachate with the fill material, and the landfill site design parameters is required to solve the problem. Three landfill sites (Gokarna, Sisdol and Pokhara) were studied as case studied to identify leakage problems in view of controlling leachate migration. Hydraulic conductivity, particle size distribution and shape of basement material were studied. Gokarna Landfill Site did not have proper clay lining or other technology that prevents groundwater contamination. The Sisdol and the Pokhara landfill sites were improved sites but were devoid of clay lining. To control leachate migration, proper basement and other design is required. The slope of the basement clay liner should be adjusted properly according to the hydraulic conductivity of the clay to prevent leachate movement downward. Similarly, selection of shape and size of drainage material is important for aeration, and to prevent from leachate clogging and puncturing the basal clay or geo-membrane. The case studies suggested need of some improvements for basal design of landfill sites for future. Besides the basement design, design of leachate suction well and vegetative technology for leachate treatment are necessary. A basement design is proposed that will be economic and suitable for developing countries. This paper discusses about some drawbacks in technical practices in some landfill sites in Nepal and suggests possible methods that can be applied in constructing landfill sites for reducing contamination.   doi: 10.3126/bdg.v11i0.1542 Bulletin of the Department of Geology, Tribhuvan University, Kathmandu, Nepal, Vol. 11, 2008, pp. 51-60

<p>The water, energy, and food security nexus (WEF Nexus) is the interlinkage between water security, energy security, and food security. An increasing world population is projected to increase energy and food requirements, which will increase the need for freshwater drastically in the coming decades. Projected climate change impacts will aggravate water availability, especially in urban areas. Nature-based solutions (NBS) have proven to generate multiple benefits that defuse the expected merging tensions within the WEF Nexus. This paper outlines the theories, provides examples, and discusses the potential of NBS to address the future WEF Nexus. For this purpose we reviewed recent papers on the theories of WE, WF, EF, and WEF Nexus, we described and summarized 19 representative real-life case studies, and we identified the knowledge gap within the theory and the case studies. We provide quantitative potentials and qualitative benefits for NBS described in the literature over the past decades. Our review demonstrated the impressive potential of NBS to address the projected challenges within the WEF Nexus. The study concludes by recommending NBS for specific WEF Nexus challenges and highlighting the need for decision-makers to consider the implementation of NBS in urban planings.</p>

Contemporary Archaeology and the City foregrounds the archaeological study of post-industrial and other urban transformations through a diverse, international collection of case studies. Over the past decade contemporary archaeology has emerged as a dynamic force for dissecting and contextualizing the material complexities of present-day societies. Contemporary archaeology challenges conventional anthropological and archaeological conceptions of the past by pushing temporal boundaries closer to, if not into, the present. The volume is organized around three themes that highlight the multifaceted character of urban transitions in present-day cities - creativity, ruination, and political action. The case studies offer comparative perspectives on transformative global urban processes in local contexts through research conducted in the struggling, post-industrial cities of Detroit, Belfast, Indianapolis, Berlin, Liverpool, Belem, and post-Apartheid Cape Town, as well as the thriving urban centres of Melbourne, New York City, London, Chicago, and Istanbul. Together, the volume contributions demonstrate how the contemporary city is an urban palimpsest comprised by archaeological assemblages - of the built environment, the surface, and buried sub-surface - that are traces of the various pasts entangled with one another in the present. This volume aims to position the city as one of the most important and dynamic arenas for archaeological studies of the contemporary by presenting a range of theoretically-engaged case studies that highlight some of the major issues that the study of contemporary cities pose for archaeologists.

Different Parts

The issue of design and democracy is an urgent and rather controversial one. Democracy has always been a core theme in design research, but in the past years it has shifted in meaning. The current discourse in design research that has been working in a participatory way on common issues in given local contexts, has developed an enhanced focus on rethinking democracy. This is the topic of some recent design conferences, such PDC2018, Nordes2017 and DRS2018, and of the DESIS Philosophy Talk #6 “Regenerating Democracy?” (www.desis-philosophytalks.org), from which this track originates. To reflect on the role and responsibility of designers in a time where democracy in its various forms is often put at risk seems an urgent matter to us. The concern for the ways in which the democratic discourse is put at risk in many different parts of the word is registered outside the design community (for instance by philosophers such as Noam Chomsky), as well as within (see for instance Manzini’s and Margolin’s call Design Stand Up (http://www.democracy-design.org). Therefore, the need to articulate a discussion on this difficult matter, and to find a common vocabulary we can share to talk about it. One of the difficulties encountered for instance when discussing this issue, is that the word “democracy” is understood in different ways, in relation to the traditions and contexts in which it is framed. Philosophically speaking, there are diverse discourses on democracy that currently inspire design researchers and theorists, such as Arendt, Dewey, Negri and Hardt, Schmitt, Mouffe, Rancière, Agamben, Rawls, Habermas, Latour, Gramsci, whose positions on this topic are very diverse. How can these authors guide us to further articulate this discussion? In which ways can these philosophers support and enrich design’s innovation discourses on design and democracy, and guide our thinking in addressing sensitive and yet timely questions, such as what design can do in what seems to be dark times for democracy, and whether design can possibly contribute to enrich the current democratic ecosystems, making them more strong and resilient?

Yongding River

Abstract Yongding River is one of the five major river systems in Beijing. It is located to the west of Beijing. It has influenced culture along its basin. The river supports both rural and urban areas. Furthermore, it influences economic development, water conservation, and the natural environment. However, during the past few decades, due to the combined effect of increasing population and economic activities, a series of changes have led to problems such as the reduction in water volume and the exposure of the riverbed. In this study, remote sensing images were used to derive land cover maps and compare spatiotemporal changes during the past 40 years. As a result, the following data were found: forest changed least; cropland area increased to a large extent; bareland area was reduced by a maximum of 63%; surface water area in the study area was lower from 1989 to 1999 because of the excessive use of water in human activities, but it increased by 92% from 2010 to 2018 as awareness about protecting the environment arose; there was a small increase in the built-up area, but this was more planned. These results reveal that water conservancy construction, agroforestry activities, and increasing urbanization have a great impact on the surrounding environment of the Yongding River (Beijing section). This study discusses in detail how the current situation can be attributed to of human activities, policies, economic development, and ecological conservation Furthermore, it suggests improvement by strengthening the governance of the riverbed and the riverside. These results and discussion can be a reference and provide decision support for the management of southwest Beijing or similar river basins in peri-urban areas.

This review of the Literacy and Education Bklletin1 of the 1961 Census is fourth in the series of review articles published in this journal2. The Bulletin under review forms a part of the interim report on the characteristics of the population of Pakistan. It gives information on the number of illiterate and literate persons by age and sex for rural and urban areas on division and district basis; illiterate and literate.population in selected cities and towns; and the educational levels attained by the literate population by age and sex for divisions and districts. Relevant statistical notes and statements precede the tables in the Bulletin. The objective of this review is to describe the meaningfulness and significance of literacy statistics. To this end, a distinction is made between formal and functional levels of literacy. Comparisons of the 1951 and 1961 census figures are undertaken to indicate the progress of literacy and education during the past decade with reference to the effect of intercensal rate of population growth on such progress. Certain questions regarding the reliability of data are raised, which emphasize the need for caution in the interpretation of literacy statistics.
