However, Europe's cities appear to be experiencing problems related to modernization and technology. Illustrative are comments of Turin's and Cologne's mayors. That is a slow and difficult long-term process that needs time and the participation of the whole city system. The risk of such urban transformation is to forget large parts of the population. Urban unemployment causes poverty, and because of such poverty, people are not capable of paying for services such as health and education.
Some African mayors link unemployment to problems related to idle youth.
Young men of Bobo-Dioulasso spend most of their time drinking tea. They don't want to work. Gaza's mayor also emphasizes inadequate housing, whereas Rafah's mayor emphasizes not enough paved roads, as other serious problems. It is predicted that Kawasaki's population over 65 years will double by the year 2010. The mayors of both Kathmandu and Tansing, Nepal, also cite water supply as their most serious problems.
