On the beginning of 20th century, cities become synonymous for progress, wealth and increasing opportunities when compared with the rural regions. Based on some UN information‘s, 30% of world population was urban in 1950, this percentage increase to 47% in 2000, and expectations are that in 2030 60% of population will live in cities. If changes in space organization do not happen until 2030, total earth population will increase to 8,1 billion and 5 billion people will live in urban regions with the 2,67 billion that will not have place to live. This change of the world, from rural to predominantly urban is continuous and cannot convert again, so these changes affect using of water, energy, earth and other nature resources. In the same time cities are primary victims of climate changes. Half of the population lives in urban regions, but they consume 80% of global energy production. Urban theorists saying that city is dead. In the future we can talk about two models of the cities that are totally different: ecological conscious city that becomes sustainable with the own resources and „ slum city ― that is fighting for the healthier life. How to deal with challenges of the global age that are barrier for progress and sustainability, and in same time keep own identity and diversity? The cities are kind‘s social - ecological systems that have a wider range of articulation with ecology. How to produce positive results – results which enabling contribution of sustainability of environment in cities? Cities are complex systems of consumption and production and that complexity makes them essential for finding solutions. Differences of the cities come from different politics of the governments, basic economy, and ordinary cultural life of the citizen‘s. One of those facts is that whole energy flow and materials of the economy become pollution and waste of ecosphere just in different shape. Are the global ecological conditions result of the urban agglomeration and density, or are they result of specific urban system types? Long time ago cities become places for innovations, development and starting of complex physical and organization systems. It is important to find solution for the big number of ecological damage and formula for reconfiguration of social – ecological systems that are made because of urbanization.
