Title : Suitaiology: Environmental protection, water resource creation and agricultural development in mountainous areas


Water, humans and the environment constitute the WHE system. The dynamic state and dynamic development trend of dynamic interactions between water and other members of the system is the so-called water situation. From the perspective of suitaiology, the natural situation of water is mainly destructive, and floods and droughts are two opposite extreme water situations. We must protect the environment while preventing floods and droughts. This is an asymmetrical competition with the dynamic Nature’s forces. Although humans have tried countless methods and technologies for thousands of years, conventional existing static water science is not enough to help us understand and deal with this dynamic asymmetric competition. New dynamic scientific theories and thinking are needed to provide guidance on strategies and techniques. Brand-new suitaiology profoundly reveals that the destructive natural situation of water is achieved through dimensionality reduction attacks. Therefore, it is clear that the key to effectively alleviating or even eliminating floods, droughts and and induced geological disasters to a large extent, creating water resources, and maintaining the delicate balance within the WHE system is to adjust the water dimensions and change the water situation through reverse operations. The methods and technologies that have been effective in the past are precisely because they conform to the scientific theory and thinking of suitaiology, but they are not enough. Facing with extreme weather challenges such as heavy rains, floods, and droughts, mountainous areas are the most vulnerable areas, but they are often ignored. We must realize that mountainous areas are the sources of floods and serve as the “water towers” of a river basin. Our goal is to minimize the formation of floods and convert excess surface water into water resources in mountainous areas. This plays a vital role in flood control, drought relief, agriculture, forestry, tourism and water supply throughout the basin. The scientific theory and thinking of suitaiology proposes two fundamental principles, namely, dimension promotion and potential adjustment. Cultivating good vegetation and building appropriate interceptions and deceleration facilities or diversion facilities on slopes to increase the dimension of water activities can significantly weaken or even eliminate the destructive effects of water. The highest art of war is not only to weaken or eliminate unfavorable situations, but more importantly, to turn unfavorable situations into favorable ones. Combining groundwater storage facilities with the control systems of the above-mentioned dimension promotion converts the originally destructive water flow into valuable water resources, effectively turning the mountainous area into an ecological "water tower" for natural water storage and energy-free water supply. During the construction of these facilities, both new agricultural lands and ecological zones can be created. The environment of each mountainous area has its own characteristics, and the methods and measures to change the water situation are also different. This time only a general discussion is given. Typical examples in different types of mountains will be gradually discussed at other times in the future.

Audiance Takeaway:

  • The audience will learn a novel scientific theory, Suitaiology, which recognizes that combating  climate change is an asymmetrical competition with the Nature’s forces, the natural situation of water is to damage the environment through dimensionality reduction attacks, dimension promotion and potential adjustment can effectively solve the water problems.
  • The audience will learn how to grasp the core points of a dynamically changing research object, and guide our actions and efforts with appropriate scientific theories that can cope with dynamic changes. If no such scientific theory is found, how to create a new one to instead.
  • The audience will learn a systematic concept, principle and approach to help them in their job.


Dr. Dachang Zhang received his B.S. and M.S. degrees in hydrogeology & Engineering Geology from the Changchun Institute of Geology and Chinese Academy of Sciences in 1982 and 1985 respectively, then became a researcher at Chinese Academy of Sciences. After his PhD degree in geography from the University of Vienna in 1996 with significant contributions to a national water project of Austria, he was a postdoctoral fellowship and researcher at the University of Waterloo, Canada from 1997-2000. And then, he worked as a consultant in Canada and U.S.A. and become a License Professional Geologist of the State of California since 2007. He also worked for the University of Bijie, China, as a Professor and the Deputy Dean of the Academy for Bijie Experimental Region for water management and rural development in impoverished mountainous areas from 2008 to 2014. He is the Founder and President of the Water &Eco Crisis Foundation, USA, since 2010. In 2012, Dr. Dachang Zhang and his team set out to create a new water science—Suitaiology, which was first officially released at the 1st Edition of Global Conference on Agriculture and Horticulture (AGRI 2021) in 2021.
