La présente contribution tente d’élucider la problématique foncière en relation avec la corruption des élites urbaines, des courtiers politiques et des acteurs de l’arène politico-administrative. En effet, il n’y a presque pas de régime politique sans scandales de corruption, sans pillage de l’économie en général et de l’économie agraire en particulier. La corruption foncière est bien organisée dans les arcanes du pouvoir aussi bien au niveau local, intermédiaire que central. On pourrait parler d’une « chaîne de corruption » foncière.

En Afrique de l’Ouest, les débats politiques autour du foncier mettent souvent en opposition deux modes d’accès à la terre et de rapports à la possession du sol : la coutume d’une part, organisant l’usage de la terre par une communauté en vertu de références sacrées, et la loi d’origine coloniale d’autre part, définissant l’attribution aux individus de la pleine propriété privée (Lavigne-Delville 2010). Nous entendons démontrer, à l’aide d’une étude empirique des stratégies citadines d’accès à la terre au Sud-Bénin1, que la situation est plus complexe dans les zones à urbanisation rapide.

La population du Sahara algérien continue, depuis plus d’un demi-siècle, à s’accroître plus rapidement que celle de l’Algérie du Nord. Plus d’un Algérien sur dix vit actuellement au Sahara, contre un sur quinze à la veille de l’Indépendance. Cette population est de plus en plus citadine et les villes importantes ne sont plus rares aujourd’hui au Sahara.

A ciência tem mostrado nas últimas décadas que a conta- minação por mercúrio (Hg) é um problema ambiental e de saúde pública. Uma importante fonte poluidora é o garim- po ilegal de ouro, que vem crescendo vertiginosamente, deixando um rastro de destruição. Outras atividades rea- lizadas por seres humanos, incluindo o desmatamento, a queimada de florestas e a construção de hidrelétricas, au- mentam os níveis de contaminação por mercúrio em cor- pos d’agua e no ambiente.

Urban planners are entrusted with the power to make critically important, long-term decisions that determine the future development of cities and towns around the world. The decisions they take shape the urban environment and directly affect the lives and livelihoods of entire communities.

Informal Land Subdivisions And Their Effects On Spatial Development In Peri Urban Areas:The Case Of Kichangani Suward In Kigamboni Municipality, Dar Es Salaam, Tanzania

Context and background               Residing in areas of flood risk informal settlements is more or less normal among low-income households in most cities of the developing countries. While living in such settlements present challenge to quality of life, many among the urban poor offer these areas.Goal and objectives:This paper analyses factors that drive urban residents to acquire land and build houses in flood prone areas.

Context and backgroundExtreme heat is one of the challenges facing urban areas. Though this constitutes a global urban challenge, especially large cities in the world, Urban studies have barely paid attention to urban heat.Goal and Objectives:This study attempts to respond to the research gap through drawing on early warning systems to explore community and governments to extreme heat, in particular, how residents adapt to extreme heat in Dar es Salaam.Methodology:Kigogo ward in the city of Dar es Salaam was selected as a case study area.

In Tanzania, the increase in the number of commercial motorcycles operating in the urban areas has resulted to the establishment of informal parking spaces in various parts of towns and cities. This research aimed to explore the criteria used by commercial motorcycle operators to establish informal motorcycle parking spaces in urban areas. The study on the influence of land use on the spatial distribution of informal motorcycle parking spaces applied triangulation techniques to ensure the validity and reliability of the collected data.

Context and background: Cities in developing world are experiencing rapid urbanization characterized by rapid population growth. Tanzania like many other most of urban areas face poor public transport which force city dwellers to use alternative transport including walking.
