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.

This publication helps guide investment planning and financing across key urban infrastructure sectors of Azerbaijan. It aims to improve the performance of cities—with a focus on economy, equity, and environment. The National Urban Assessment for Azerbaijan is among a series prepared by ADB for selected developing countries under its Urban Operational Plan 2012–2020.

À Madingou, la question de la gestion foncière se pose avec acuité, car le développement des espaces urbains empiète sur les terres dévolues à l’agriculture périurbaine. Ce phénomène reconnu par les autorités municipales et les populations est à la fois à l’origine de la croissance anarchique de la ville et au rétrécissement préoccupant des superficies agricoles périurbaines. L’objectif de cette étude est d’analyser l’impact de la gestion foncière sur l’agriculture périurbaine à Madingou. Elle est réalisée entre janvier et mars 2017.

ncreasing flood risks in Thailand are leading to new challenges for flood management and subsequently for livelihoods, which are still significantly agricultural. Policy makers prefer building flood protection infrastructure over utilizing non-structural measures like urban planning regulations to mitigate risks. We argue that unplanned urbanization intensifies flood risks and livelihood vulnerability and may even create new poverty patterns in peri-urban areas.

Urbanization contributes to the emerging urban areas across the world. The importance of geology to ensure sustainability, has led to many research publications in the urban geology. This paper aims to discover the research trends through a bibliometric analysis of articles indexed within the Scopus database from 1950 to 2018 on topics related to geology and urban. The analysis found a significant increase in publications during 1999-2016, especially after the 2004 Indian Ocean earthquake and tsunami disaster.

Under certain circumstances, land titling, property regime changes, and land‐use conversions yield substantial profits. Yet few people possess the wealth, knowledge, and networks to benefit from these procedures. In the Yucatán Peninsula, a region recently targeted as a prominent investment location by the Mexican national government (mainly with the “Tren Maya” megaproject) and the private capital, forestlands collectively owned as ejidos by Mayan peasants are on the trend to complete privatization.

The recent increase in rainstorm waterlogging disasters has acutely threatened sustainable urban development in China. Traditional strategy to solve this problem is drainage capacity enhancing projects, which aims at enlarging the discharge of water. Recently, there is a new countermeasure emerged in Chinese cities: ‘Sponge City’, which aims at enlarging the absorption of water by increasing the curves of urban land.

Taking the Bohai Economic Rim as the research area and 44 prefecture-level cities as research objects, on the basis of deepening the connotation of urban land use morphology, we constructed a multi-dimensional indicator system for urban land use transition based on the dominant and recessive morphologies of land use.

The development of social production and the agglomeration of the urban population have brought tremendous pressure to transportation infrastructure. However, the impacts of transportation development on urban land use systems have not been well investigated. Under the pressure of limited land resources, the impact of transportation infrastructure on urban land use efficiency (ULUE) is receiving increasing attention from scholars and needs to be explored.

To understand the urbanization process, it is essential to detect urban spatial growth and to study relations with social development. In this study, we take Wuhan as a case to examine urban land growth patterns and how social factors relate to the urban land evolution between 1990, 2000, and 2010. We first classify land cover using Landsat images and examine the urban growth patterns during various stages based on landscape metrics regarding the area, density, and shape. Afterwards, principal component analysis and census data are used to extract key social factors.

Strong national institutional arrangements in the geospatial information management are essential for successful implementation of sustainable land administration system. However, it is not only the existence of institutions but also their effectiveness that leads to the intended goals and reaching of objectives.

Land use planning as strategic instruments to guide urban dynamics faces particular challenges in the Global South, including Sub-Saharan Africa, where urgent interventions are required to improve urban and environmental sustainability. This study investigated and identified key challenges of land use planning and its environmental assessments to improve the urban and environmental sustainability of city-regions.
