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 agrícolas y naturales. Si bien los procesos de urbanización y metropolización han favorecido el desarrollo económico del país, también han tenido efectos negativos, tales como un aumento de la desigualdad

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. Here we present an assessment of current and future flood risk in five countries of mainland Southeast Asia, using a new modeling approach that accounts for differences in urban land systems.

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. Launching as a call to action for national governments ahead of COP26 in Glasgow, it builds on the Coalition’s flagship 2019 report: Climate Emergency, Urban Opportunity.

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). We estimated population change from the Global Human Settlement Layer Population spatial grids, a set of population density layers used to measure human presence and urbanisation on planet Earth.

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. This paper compared the evolution in the distribution and scale of Suzhou gardens among five historical periods, and discussed the influence of urbanization on gardening.

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. Par ailleurs,d’autres facteurs contextuels s’invitent pour donner lieu à des effets irréversibles tels que: la prolifération de quartiers sousintégrés.

The process of urbanization in China has been accompanied by the conflict of land expropriation, which is not conducive to social stability. Different from the previous angles and methods of studying the conflict of agricultural land expropriation, this study puts forward a new behavioral perspective on the basis of game theory, and constructs an evolutionary game model of the conflict of agricultural land expropriation in China from the perspective of multi-dimensional preference.

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. The relation between LULC change and ES is still poorly examined and quantified using actual field data. In most ES studies, GS is perceived as lumped areas instead of distributed areas, implicitly ignoring landscape patterns (LP), such as connectivity and aggregation.

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. The establishment of national new urbanization pilot areas is an important element of the new urbanization policy. This paper tests the policy effect of the National New-type Urbanization Plan (2014–2020) on in situ urban development through the establishment of pilot areas.

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. These processes of expansion into the peri-urban, however, create tension regarding land use and land rights, and may foster tenure insecurity if not well managed.

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. The results show the following: (1) From 2002 to 2019, the HQ in the study area decreased significantly, and the spatial differences gradually expanded over time. The HQ was low in the southwest and high in the northeast, and low-level habitats gradually moved to the southwest.
