"Decades of practice in our country show that urban development plans based on expansionist principles have not succeeded in preserving the biological essences of our cities. In contrast, the work of myself and my colleagues across various projects has demonstrated that the biological essences of cities — which are considered fundamental and generational assets of the citizens — must be protected through active stewardship. This requires studies grounded in ecological research and environmental design. Within the framework of the dos and don’ts that these disciplines define, appropriate options can be selected. It is only within this framework — which constitutes a foundation of sustainable development — that urban planning and implementation should proceed."
