The government has recognized the concept of Environmental Planning as one of its principal instruments for the establishment of a comprehensive system which seeks to conserve, rehabilitate and develop the physical environment and natural resources; and, for the translation into physical and spatial considerations policies on land capability, urbanization, agricultural development and natural development resources.
