Mondal, Pragya Sharma, Debolina Kundu, Sarita Bansal","doi":"10.1177/09754253211007830","DOIUrl":"https://doi.org/10.1177/09754253211007830","url":null,"abstract":"Urbanization is considered as the key driver for land use and land cover (LULC) changes across the globe and Delhi is no exception to this phenomenon. The population of Delhi has almost doubled from 8.4 million in 1991 to 16.3 million in 2011. Correspondingly, the built-up area has also increased from 336.82 to 598.22 km 2 during 1999–2018. This urban expansion has led to emergence of serious ecological risk and fragmentation of the landscape. In this context, it is imperative to analyse the level of risks induced by such urban expansion and its underlying associations with other factors. This article quantifies the LULC changes in Delhi during 1999–2018 using Landsat 5 (TM) and Landsat 8 (OLI) data. A spatio-temporal sprawl induced risk assessment index has been developed by combining landscape fragmentation score and land use land cover vulnerability score. The landscape fragmentation score was based on four landscape metrics, whereas the vulnerability score was computed from LULC data. The article also assesses the association between risk areas and economic activities, environmental and infrastructural amenities that are considered key drivers of urban expansion in Delhi. To estimate spatio-temporal variability between risk areas and key drivers, ordinary least square regression and geographical weighted regression (GWR) were used. The GWR results reveal that sprawl-induced ecological risk in Delhi is strongly associated with economic activity, infrastructural accessibility and environmental amenities. This spatial empirical assessment also shows that urban growth incentives or services such as roads, metro rail, schools and hospitals can also create pressure on the landscape if local authorities arbitrarily provide these services across space without considering the associated risks.","PeriodicalId":44690,"journal":{"name":"Environment and Urbanization ASIA","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/09754253211007830","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45943415","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}

While the demand for fossil energy increases during the process of urbanization, different nations rely upon different sources of fossil energy. As such, a one-size-fits-all approach in reducing the consumption of fossil fuels to improve the quality of the environment is neither logical, nor practical. This study investigates the short-term and long-term effects of urbanization in relation to fossil energy consumption from coal, gas and oil. The auto-regressive distributed lag (ARDL) is employed on the sample of five emerging ASEAN nations in the 1985–2018 period. The findings reveal that that urbanization in Indonesia, Malaysia and Thailand appears to be associated with an increase in coal consumption in the short run. In Vietnam, gas consumption will increase with urbanization. However, in the long run, urbanization in Thailand and Vietnam is linked to an increase in oil consumption. Urbanization in Indonesia, Malaysia and the Philippines leads to the reduction of coal consumption in the long run. Policy implications have emerged based on the findings of this study.","PeriodicalId":44690,"journal":{"name":"Environment and Urbanization ASIA","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/0975425321990378","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48354110","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}

This article highlights the limits of analysing densification at the city scale and advocates for a more granular approach. The case study of Cape Town shows how overall consolidation has been mainly driven by poor households crowding into already dense neighbourhoods on the urban periphery. This has aggravated historic segregation and intensified urban management challenges. Meanwhile, formal private sector driven densification strengthens the social and economic vibrancy of affluent neighbourhoods. This article argues that uneven residential patterns reflect deep-seated social inequalities that are amplified through labour and property markets. Satellite data also illustrates how Cape Town’s built-up area has changed between 1998 and 2019. Based on geo-spatial analyses, the article suggests that taking these drivers seriously is crucial to promoting a denser and more equitable urban form. Aligning housing policies with spatial transformation and economic development objectives offer possibilities for change.","PeriodicalId":44690,"journal":{"name":"Environment and Urbanization ASIA","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/0975425321998026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47177730","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}
