Environmentally sustainable development in cities, with an emphasis on urban agriculture approach

Abstract

In the contemporary capitalism, the city is considered as a good and urbanization place as a way of desirable life. Permeate and influence of the culture of capitalism in the Third World, including Iran is caused non-heterogeneous urban concentration and rapid urban population growth of massive migration of rural-urban: a process which in fact led to the transfer of mainly poor population in cities. A clear example of this type of confrontation can be seen in old and rural tissues of modern cities. Migration from rural areas to urban areas is a global phenomenon which is led to immensely growing of cities and marginalization. Important reason for migration from rural to urban areas is economic pressure. Rural landscape and urban peripheries which is includes farmland, orchards or wasteland, is of particular importance depending on the geographical situation of the city, historical background and ecological aspect of a land that seems often to be exposed to devaluing the local values, agricultural, ecological and increasing its value for urban development demand because of the spurt growth. Understanding and maintaining the ecological systems as well as maintaining ecological diversity and ensuring environmental sustainability, especially for arid and semi-arid regions, is important due to limited natural resources. Maintaining ecosystems is valuable for sustainable development and survival and a place where rapid and often irreversible environmental degradation begins, Justifying the need for attention to it. In this regard, Participation and communication approach that is includes local preferences and needs and consistent with local and regional context, is the main mechanism, redefining mentioned areas and the way of its design.
