As of 2014, 54% of the earth’s population resides in urban areas, and it is steadily increasing, expecting to reach 66% by 2050. Urban areas range from small cities with tens of thousands of people to megacities with greater than 10 million people. Roughly 12% of the global population today lives in 28 megacities, and at least 40 are projected by 2030. At these scales, the urban infrastructure ...

Soils in older areas of cities are highly contaminated by lead, due largely to past use of lead additives in gasoline, the use of lead in exterior paints, and industrial lead sources. Soils are not passive repositories and periodic re-suspension of fine lead contaminated soil dust particulates (or aerosols) may create seasonal variations of lead exposure for urban dwellers. Atmospheric soil and...

As the population continues to increase, many problems arise which make the PTS an unreliable and inefficient service provider. So, providing a good PTS is r...

Health problems linked to urban growth are current major concerns of developing countries. In 2002 and 2005, an interdisciplinary program “Populations et Espaces à Risques SANitaires” (PERSAN) was set up under the patronage of the Development and Research Institute. Centered on health in Cameroon’s urban environment, the program mainly sought to (i) identify diarrhoea risk factors in Yaoundé, (...

The proliferation of mobile communication and digital media has altered our presence in the urban environment and the way we perceive the city. The topology of our sensory domain has been rendered steadily more complexly connected, recapitulating deployments of wearable and ubiquitous technologies, as today we are frequently in one location but engaged (using one or more senses) with people and...
