urbanisation

México ha transitado por un proceso de cambios territoriales importantes en las últimas décadas; sin embargo, las políticas de vivienda de los últimos años, las modificaciones constitucionales sobre la propiedad agraria y la falta de una aplicación rigurosa de los instrumentos de planeación y de Ordenamiento Territorial (OT), entre otros factores, aceleraron la expansión urbana sobre áreas agrí

Countries in Southeast Asia have been developing quickly from a predominantly rural to predominantly urban society, leading to a rapid increase in urban land. This increase in urban land has mainly occurred in river deltas and floodplains, exposing humans and human assets to flood hazard.

Today, the Coalition for Urban Transitions releases a new report ‘Seizing the Urban Opportunity’, which provides insights from six emerging economies on how national governments can recover from COVID-19, tackle the climate crisis and secure shared prosperity through cities.

This study assesses the global mountain population, population change over the 1975–2015 time-range, and urbanisation for 2015. The work uses the World Conservation Monitoring Centre (WCMC) definition of mountain areas combined with that of mountain range outlines generated by the Global Mountain Biodiversity Assessment (GMBA).

Suzhou city was the cultural centre of ancient south China. It continues the urban pattern of more than 800 years ago. Suzhou gardens are the essence of Chinese gardening art, as well as the valuable world cultural heritage site.

Indicator 11.3.1: Ratio of land consumption rate to population growth rate
 

La ville de N’Djamena, capitale de la République du Tchad connaît sans cesse, depuis sa création en 1900, une extension urbaine qui se traduit par une consommation démesurée de l’espace. Un état de fait rendu possible durant des décennies par différents facteurs antagonistes issus de l’absence et/ou de l’insuffisance de l’autorité de l’Etat.

The process of urbanization in China has been accompanied by the conflict of land expropriation, which is not conducive to social stability.

Urbanization is changing land use–land cover (LULC) transforming green spaces (GS) and bodies of water into built-up areas. LULC change is affecting ecosystem services (ES) in urban areas, such as by decreasing of the water retention capacity, the urban temperature regulation capacity and the carbon sequestration.

Compared with traditional urbanization, new urbanization is more closely aligned with China’s basic national conditions and reflects the basic goal of sustainable development. As the main method of new urbanization, in situ urbanization can make up for the shortcomings of traditional urbanization.

As the global population continues to urbanize, increasing pressure is put upon urban centers and the carrying capacity of the already built-up areas. One way to meet these demands is horizontal expansion, which requires new lands to become incorporated into urban centers. In most cases, this demand is met by converting peri-urban land into urban land as the urban center expands.

This paper, examining the Pilot Free Trade Zone Lin-Gang Special Area in China (Shanghai), identifies the relationship between urban expansion and habitat change and analyzes the influence mechanism of habitat quality (HQ) on spatiotemporal distribution.
