The Berlin blockade was an attempt by the Soviet Union to block the roads to the French, British and American sectors of the city of Berlin. The Soviet Union wanted these Western powers to relinquish their claims to parts of Berlin. These sectors were within the Russian-occupied East Germany. It is considered the first major clash between the Soviet Union and the USA during the Cold War. This blockade was instituted three years after the end of the Second World War. Eventually, the French, British and Americans airlifted supplies into West Berlin. 

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
