Urbanization and forest degradation in east Africa - a case study around Dar es Salaam, Tanzania

2016

In this paper we examine the impact of the growing urbanization of Dar es Salaam, Tanzania, on the forest areas around the city. Since 1990 the city has seen an annual population growth rate of over 4%. We document the expansion of the city over the last 30 using the Global Human Settlement Layers, derived from the global Landsat archive. At the same time we show the depletion, of the surrounding forests that has occurred to meet the growing demand for agricultural land, fuel wood and construction material over the same period. The impact on these forests as a result of the demand from an expanding urban conglomeration is higher than would be expected from a dispersed population increase. T…

Influenza del cambiamento climatico e dell’urbanizzazione sull’idrologia dei bacini idrografici

2019

I cambiamenti climatici e il fenomeno del consumo del suolo sono senz’altro i fattori che più influenzano la risposta idrologica di un bacino sia in contesti urbani che extraurbani. L’aumento del grado di urbanizzazione dei bacini naturali, inteso come aumento della frazione impermeabile del suolo derivante della costante copertura di aree del bacino con materiali impermeabili artificiali come asfalto e cemento, è un fenomeno in costante crescita a livello globale. A tali cambiamenti si sovrappongono i cambiamenti climatici in atto che, fra gli effetti principali, tendono a modificare la quantità e la modalità con cui le piogge arrivano al suolo e, al contempo, inducono alterazioni al regim…

Mutations urbaines et logiques de localisation des emplois: le cas de la Communauté de l'agglomération dijonnaise (1990, 1999).

2004

The aim of this paper is to analyze the spatial changes in the Dijon urban area (COMADI) by studying in particular the new tendencies of localization of the high order producer services. Our results display a multicentric structure of the COMADI which exhibits several employment poles. Not only the economic composition of these poles differs between the central pole and the peripheral ones but this composition changes over the study period (1990-1999). New localization logics appear for the high order services : if the historical center remains specialized in financial activities, insurance and real estate (FIRE), the other producer services are more likely to be localized in the periphery.…

The airport as edge city : the case of Paris' Charles de Gaulle airport

2005

International audience; Most of the recent research about airports has considered them in their role as points within airline networks,and the focus has been generally on hub airports. But airports are also places offering many similarities with cities, particularly with edge cities. They are places of human diversity and job centers for surrounding areas. Traffic jams are common on ground facilities as they are on taxiways, runways and airways. Often divided in specialized districts, such as cargo warehousing, hotel rows, rental car parking lots or office clusters, they are also urban organisms exerting strong demands on the local environment. In the post 9-11era, their importance for econ…

Emerging Trends, Issues, and Challenges in Big Data and Its Implementation toward Future Smart Cities

2017

The articles in this special section focus on Big Data as it impacts future smart cities. The world is experiencing a period of extreme urbanization. Moreover, this process will continue, and the global urban population is expected to double by 2050. Smart city has been proposed to improve the efficiency of services and meet residents’ needs for better quality of life. Essentially, smart city integrates the Internet of Things and emerging communication technologies such as fifth generation (5G) solutions to manage the citys’ assets, including transportation systems, hospitals, water supply networks, waste management, and so on. Therefore, smart city is driving innovation and new technologie…

Regional Policy Lessons from Finland

2005

The Finnish economy and society has long been dominated by primary production. Post-war economic development was rapid and welfare gaps between the much more developed economies and Finland narrowed and were even partly reversed. Rapid economic expansion together with structural change has had the effect of centralizing both economic activity and population. The trend has been towards the southern and central regions where the metropolitan area of Helsinki and most of the other larger towns and urban centres are located. Together with vigorous technological progress in agriculture and forestry the rapid urbanization and industrialization of the 1960s and 1970s the fastest in Europe altered …

URBANIZATION PROCESSES AND ITS SPECIFICS IN LATGALE

2010

<p>Urbanization is an important demo-geographical process and a complex social phenomenon under impact of which changes are made not only to the global, regional or national settlement systems, but all socio-economic processes are also substantially transformed. Changes caused by urbanization have an impact on traditional way of life, cultural particularity, community and individual psychology and other aspects of spiritual life, therefore expressions and regularities of this process might be of interest not only for demographers, geographers and economists, but also for representatives of the field of humanities.</p><p>Paper presents the progress of urbanization processes…

Changes in spatial and sectoral patterns of employment in Ile-de-France, 1978-1997

2006

International audience; This paper investigates the spatial distribution of employment in the region of Ile-de-France in 1978 and 1997. Exploratory spatial data analysis is used to identify employment centres and a sectoral analysis of the central business district (CBD) and sub-centres is performed. The results highlight a process of suburbanisation of employment in Ile-de-France between 1978 and 1997. A more polarised space emerges in 1997 than in 1978, with several employment centres specialised in different activities. Moreover, even if the spatial influence of the CBD declines over the study period, the CBD maintains its economic leadership by concentrating a large variety of high-orde…
