Urban ecology in a developing world: why advanced socioecological theory needs Africa

Journal Articles & Books
Décembre, 2013
Afrique du Sud

Afrique australe

Socioecological theory, developed through the study of urban environments, has recently led to a proliferation of research focusing on comparative analyses of cities. This research emphasis has been concentrated in the more developed countries of the Northern Hemisphere (often referred to as the “Global North”), yet urbanization is now occurring mostly in the developing world, with the fastest rates of growth in sub‐Saharan Africa.

Modelling urban growth evolution and land-use changes using GIS based cellular automata and SLEUTH models: the case of Sana’a metropolitan city, Yemen

Journal Articles & Books
Décembre, 2013
Yémen

An effective and efficient planning of an urban growth and land use changes and its impact on the environment requires information about growth trends and patterns amongst other important information. Over the years, many urban growth models have been developed and used in the developed countries for forecasting growth patterns. In the developing countries however, there exist a very few studies showing the application of these models and their performances.

integrated approach to environmental quality assessment in a coastal setting in Campania (Southern Italy)

Journal Articles & Books
Décembre, 2013
Italie

The coastal region of Southern Italy’s Caserta province, known as the Litorale Domitio (Domitia coast) has been subjected to increasing pressure from unsustainably fast economic and urban growth in the last century, that resulted in a induced serious land degradation. To obtain a comprehensive picture of the ecological status of the Domitia coastal zone (Campania, Southern Italy), a holistic methodology has been applied. Sedimentological, geochemical, and biological analyses of the surface sediments and water samples were performed along the submerged beach.

Land-use change in the ‘edgelands’: Policies and pressures in London's rural–urban fringe

Journal Articles & Books
Décembre, 2011
Royaume-Uni

Green Belt policies have helped to create chaotic landscapes at the rural–urban interfaces of the United Kingdom's largest cities. Their prime functions, to control urban sprawl and preserve an encircling green girdle to separate the urban from the open countryside, have created ‘edgelands’ that have been remarkably dynamic despite relatively strong controls on certain types of development.

Multi-agent based modeling of spatiotemporal dynamical urban growth in developing countries: simulating future scenarios of Lianyungang city, China

Journal Articles & Books
Décembre, 2015
Chine

Urbanization is the most typical form of land use/cover change, and exploration of the driving mechanism of urban growth and the prediction of its future changes are very important for achieving urban sustainable development. In view of the ability of a multi-agent system to simulate a complex spatial system and from the perspective of combining macroscopic and microscopic decision-making behaviors of agents, a spatiotemporal dynamical urban growth simulation model based on the multi-agent systems has been developed.

Monitoring land-use change-associated land development using multitemporal Landsat data and geoinformatics in Kom Ombo area, South Egypt

Journal Articles & Books
Décembre, 2012
Égypte

Due to the progressive increase in population, sustainable development of desert land in Egypt has become a strategic priority in order to meet the increasing demands of a growing population for food and housing. Such obligations require efficient compilation of accurate land-cover information in addition to detailed analysis of archival land-use changes over an extended time span. In this study, we applied a methodology for mapping land cover and monitoring change in patterns related to agricultural development and urban expansion in the desert of the Kom Ombo area.

Emergy-based evaluation of peri-urban ecosystem services

Journal Articles & Books
Décembre, 2011
Global

Peri-urban areas are often characterized by valuable natural environments that provide essential life-support functions and ecosystem services for urban residents. Global environmental change has raised concerns over how urbanization and land use and land cover change affect ecosystem services. This study applied systems ecology theory and ecological energetic analysis to value the worth of natural environment and ecosystem services to a socioeconomic system. We begin with a general discussion of peri-urban areas and their ecosystem services.

Determining misuse of agricultural lands in Yenimahalle district of Ankara using GIS and remote sensing techniques

Policy Papers & Briefs
Décembre, 2012

This study is carried out to determine land use changes by Geographic Information Systems and Remote sensing methods in Yenimahalle district of Ankara province. Changes in land use were identified between 2000-2005 and 2000-2010. For the study Landsat-5 image of year 2000, Ikonos image of year 2005, and SPOT image of year 2010 were used. 1:25000 scale topo maps and soil maps, and CORINE land use data were also used. GPS data collected from field were used for ground truth studies.

Improved monitoring of urbanization processes in China for regional climate impact assessment

Journal Articles & Books
Décembre, 2015
Chine

Regional climate is influenced by land surface processes through energy exchange between land and atmosphere at various scales. The performance of climate model simulation is largely influenced by land cover parameterization, especially over areas that experience rapid change of land surface characterization. Accurate land cover datasets suited for climate modeling are urgently needed to improve model parameterization for better simulation.

Implementing GIS regression trees for generating the spatial distribution of copper in Mediterranean environments: the case study of Lebanon

Journal Articles & Books
Décembre, 2013
Liban

Soil contamination by heavy metals has become a widespread dangerous problem in many parts of the world, including the Mediterranean environments. This is closely related to the increase irrigation by waste waters, to the uncontrolled application of sewage sludge, industrial effluents, pesticides and fertilizers, to the rapid urbanization, to the atmospheric deposition of dust and aerosols, to the vehicular emissions and to many other negative human activities.

impacts of urbanization on air quality over the Pearl River Delta in winter: roles of urban land use and emission distribution

Journal Articles & Books
Décembre, 2014

In this study, ideal but realistic numerical experiments are performed to explore the relative effects of changes in land use and emission distribution on air quality in the Pearl River Delta (PRD) region in winter. The experiments are accomplished using the Lagrangian particle transport and dispersion model FLEXPART coupled with the Weather Research and Forecasting model under different scenarios.

Managing urban growth in a transforming China: Evidence from Beijing

Journal Articles & Books
Décembre, 2011
Chine

Managing urban growth in the current rapid urbanization process has become a key issue for land use policy in transformation China. This paper maps and assesses the performance of urban containment strategies in China, looking at the case of Beijing over a 19-year period (1990–2009). The analysis shows that to a large extent containment strategies perform well in terms of concentrating urban growth in planned suburban areas and promoting compact development.
