of cities are showing symptoms of environmental and socioeconomic stress. In many parts of

the world especially in the South, urbanization was rapid in the past few decades but it was

not planned properly, thus producing unorganized-infrastucture cluster of communities rather

than� proper ones. Without careful attention to the creation of sustainable human settlements,

the goals of sustainability will be impossible to realize. Extension of cities often results in loss

of agricultural area, greenbelts, natural ecosystems and animal habitats. It also deplete

resources from and transfer of wastes to rural areas.� While surrounding indigenous cultures

are altered as a consequence of urban lifestyles, inside the city itself poverty increases and

overpopulation localizes. Existing facilities are unable to serve influx of immigrants who hope

for job opportunities and better lives in the city which their native land as well, with originally

low resources endowed, failed to provide sufficient yields. Many amenity are overburdened,

hence quality and quantity of services decline. For poor countries, the probability to get

unfuntional facilities replaced or at least get them refurbished is quixotic since such public

facilities require a lump sum of fiscal. Where the country cannot provide basic needs to

sustain the poor adequately, it is irrational to ask for a loan to construct new transportation

option in the city as far as the current ones still move. In contrary, rich countries have never

decelerated their modern development. Innovation per se is precious but decent

implementation is prior. While current technology and facilities is proper enough, Upgrading

to obtain higher performance may lead to wasteful consumption of resources unless it is the

energy optimization technology. Thus despite of its small population, urbanization as such
