The National Green Tribunal on March 22, 2016 sought re-demarcation and exact classification of Gram Sabha land encroached by BSES at Village Asola in Delhi.
This study investigated impacts of urban forms on the future thermal environment over Beijing, the capital city of China. Beijing is experiencing remarkable urban expansion and is planned to undergo the transformation of urban forms from single-centric (compact-city)to poly-centric city (dispersedcity). Impacts of urban forms on the future thermal environment were compared and evaluated by conducting numerical experiments based on a regional atmospheric model coupled with a singlelayer urban canopy model as well as future climate forcing output from a global climate model.
Given the increasing impacts of flooding in Jakarta, methods for assessing current and future flood risk are required. In this paper, we use the Damagescanner-Jakarta risk model to project changes in future river flood risk under scenarios of climate change, land subsidence, and land use change. We estimate current flood risk at USD 143 million p.a. Combining all future scenarios, we simulate a median increase in risk of +263 % by 2030. The single driver with the largest contribution to that increase is land subsidence (+173 %).
Urbanization, a major driver of global change, profoundly impacts our physical and social world, for example, altering not just water and carbon cycling, biodiversity, and climate, but also demography, public health, and economy. Understanding these consequences for better scientific insights and effective decision-making unarguably requires accurate information on urban extent and its spatial distributions.
Urban sprawl costs the American economy more than US$1 trillion annually, according to a new study by the New Climate Economy. These costs include greater spending on infrastructure, public service delivery and transportation. The study finds that Americans living in sprawled communities directly bear an astounding $625 billion in extra costs.
Cities in developing countries are experiencing unprecedented urban growth. Unfortunately, this is often accompanied by the negative impacts of sprawl as a result of rapid motorization such as congestion, air pollution, greenhouse gas emissions, inefficient use of energy and time, and unequal accessibility.
Intense urban and agricultural development alters habitats, increases fragmentation, and may decouple trophic interactions if plants or animals cannot disperse to needed resources. Specialist insects represent a substantial proportion of global biodiversity and their fidelity to discrete microhabitats provides a powerful framework for investigating organismal responses to human land use.
A new report recommends that China curb rapid urban sprawl by reforming land requisition, give migrants urban residency and equal access to basic public services, and reform local finances by finding stable revenues and by allowing local governments to borrow directly within strict central rules.
Conversion to urban landforms has consequences for regional climate and the many inhabitants living within the built environment. The purpose of our investigation was to explore hydroclimatic impacts of 21st century urban expansion across the United States and examine the efficacy of commonly proposed urban adaptation strategies in context of long-term global climate change.
