Urbanization

<p>Urbanization is the study of the socialpolitical and economic relationships in cities and someone specializing in urban sociology studies those relationships. In some ways cities can be microcosms of universal human behavior while in others &nbsp;they provide a unique environment that yields its own brand of human behavior. There is no strict dividing line between rural<br/>and urban; rather there is a continuum where one bleeds into the other. However once a geographically concentrated population has reached approximately 100000 people it typically behaves like a city regardless of<br/>what its designation might be. Urban development covers infrastructure for<br/>education health justice solid waste markets street pavements and cultural heritage protection. These constructions usually form part of specific sector programmed including capacity building measures. Special attention is also paid to slums of large cities. Rehabilitation and reconstruction comprises in particular social infrastructure following natural disasters or conflicts.</p><p></p>
