Landscape of Evin-Darake
Brief/
During recent decades, Tehran County has faced a considerable growth in urban dwellers. This huge rate of urbanism and subsequent use of land for urban habitation, without taking the environmental potentials into account, has caused serious consequences and has led to environmental destruction in Tehran and a disruption of the balance between the county and the environment.

Urban river valleys, as one of the elements of ecological structure of cities, can play an efficient role in creating a balance between the human-made city structure and nature, but their widespread use has caused a hyper-pressure on the natural environment resulting in the waste of natural elements such as trees, vegetation, water pollution, etc. Thus, providing and increasing recreational places, planning natural environments in order to save and revive natural ecosystems and the optimum exploitation of them appears to be absolutely vital.
