A social-ecological perspective for emerging cities: The case of Corniche promenade, “urban majlis” of Doha

In the past decade, the capital city of Doha of the State of Qatar has experienced rapid urban expansion and other changes due to globalization, which has caused (i) the loss of a compact urban pattern, (ii) landscape fragmentation, and (iii) deficiency of green spaces. Therefore, as envisioned by Qatar National Vision 2030 (QNV-2030), the State of Qatar plans to invest substantial funds into the urban regeneration of the built environment, along with the development of large areas of public parks as a means of promoting more sustainable urban development and enhancing city residents’ well-being. Accessibility contributes to the usability of public facilities on the part of the neighborhood community, thus enhancing city dwellers’ well-being. Nonetheless, the authors argue, the urban network along Doha’s Corniche promenade, the dominant open public space and the spine of the city, lacks connectivity at various scales of space. Therefore, this research study aimed to assess the existing conditions of Doha’s Corniche and recommend strategies for implementing its integration into the newly emerging city’s urban fabric. The findings, revealed through a network-analysis investigation based on graph theory, allowed us to generate a framework for shaping open public spaces, promoting higher living standards through a green network system planned at the city scale. The proposed framework addresses social-ecological challenges of distinctive open public spaces and helps define an approach for (i) tailoring the accessibility of open public spaces to their surroundings, and (ii) enhancing city dwellers’ well-being.

Urban livability and contextual uncertainties: An assessment of livability through the lens of urban dwellers in Guwahati, India

The frenetic pace of urban growth in India has caused major concerns regarding the quality of urban livability. Thus, constructing livable cities has become a major goal for new urbanization in India. But urban livability as a behavioral function of the interaction between urban environment and individual characteristics is still understudied. Therefore, to enhance urban livability and construct people-oriented livable cities, this research study aimed to understand the perception of the residents of Guwahati, India, on urban livability and its determinants. Following the notion of uncertain geographic context problem (UGCoP), the current study developed an appropriate conceptual and methodological framework that evaluated the residents’ satisfaction with urban livability and the effect of its dimensions using statistical methods, which were exploratory factor analysis, structural equation modeling and Spearman’s rank correlation. The empirical results of the study indicate that residents’ mean satisfaction with the city’s livable condition is above dissatisfaction level (2.735) and the four examined dimensions have a positive influence upon residents’ satisfaction with urban livability. Additionally, different socio-economic attributes also exert significant effects on the overall satisfaction with urban livability. Therefore, this study is a practical example and model reference for enhancing urban livability in India, particularly for fast-growing cities.

India’s demographic dividend or disaster? Mismanaged factors of production—Land, labor, infrastructure, cities

India entered its so-called demographic dividend around 2005—expected to last until 2055. India has already utilized almost a third of the period of its demographic dividend—it saw a period of explosive growth from 2003–2012—but has not been able to sustain that growth. And since 2012, growth has generated less and less employment, as it has turned inward, and so it is not helping the working-age population get usefully employed. The labor force participation rate for women has been low and is now falling. What can be done to use India’s underlying factors of production better to generate greater, more inclusive, and sustained prosperity for its citizens? These second-generation reforms are not easy, as they need cooperative federalism and much broader consensus, but without them India’s demographic dividend may become a disaster.

Advances in atom transfer radical polymerization of modified grain

Atom transfer radical polymerization (ATRP) is a kind of controllable reactive radical polymerization method with potential application value. The modification of graphene oxide (GO) by ATRP reaction can eﬀectively control various graft polymer molecules Chain length and graft density, giving GO diﬀerent functionality, such as good solvent dispersibility, environmental sensitive stimulus responsiveness, biocompatibility, and the like. In this paper, ATRP reaction and GO surface non-covalent bonding ATRP polymer molecular chain were directly initiated from GO surface immobilization initiator. The ATRP reaction modified GO was reviewed, and the process conditions and research methods of ATRP modification reaction were summarized, as well as pointed out the functional characteristics and application prospect of GO functionalized composites.

Graphene and nanocomposites—Imprints on environmentally sustainable production and applications based on ecological aspects

Graphene, an innovative nanocarbon, has been discovered as a significant technological material. Increasing utilization of graphene has moved research towards the development of sustainable green techniques to synthesize graphene and related nanomaterials. This review article is basically designed to highlight the significant sustainability aspects of graphene. Consequently, the sustainability vision is presented for graphene and graphene nanocomposites. Environmentally sustainable production of graphene and ensuing nanomaterials has been studied. The formation of graphene, graphene oxide, reduced graphene oxide, and other derivatives has been synthesized using ecological carbon and green sources, green solvents, non-toxic reagents, and green routes. Furthermore, the utilization of graphene for the conversion of industrial polymers to sustainable recycled polymers has been studied. In addition, the recycled polymers have also been used to form graphene as a sustainable method. The implication of graphene in the sustainable energy systems has been investigated. Specifically, high specific capacitance and capacitance retention were observed for graphene-based supercapacitor systems. Subsequently, graphene may act as a multi-functional, high performance, green nanomaterial with low weight, low price, and environmental friendliness for sustainable engineering and green energy storage applications. However, existing challenges regarding advanced material design, processing, recyclability, and commercial scale production need to be overcome to unveil the true sustainability aspects of graphene in the environmental and energy sectors.
