Title : Suitaiology — systematic precision control of waters secures the environment and agriculture in mountains


Mountains are the most abundant biodiversity with vertical zoning, and are the ecological
barriers of the entire watershed. Mountain agriculture and forestry play an irreplaceable role in
the agricultural economic system. Bare rocks, valleys, forests, pastures and alpine snow areas
provide rich tourism and leisure resources. Mountains are also recharge areas of surface and
underground water resources in basins. The negative troubles that mountains bring to humans are
all related to water. With too little rain in the dry season, mountains cannot provide enough water
resources for themselves and the downstream. On the other hand, too much rain can easily make
mountains a source of floods. Rainwater hits mountains, carving out the most complex landform
in the watershed, which may often induce geological disasters such as mud rock flows, landslides
and collapses. Today, extreme weather occurs frequently, seriously endangering the mountain
environment and ecology. Although natural change is a natural process, for a human society that
expects stable development, something needs to be done to alleviate the adverse natural change.
People are trying hard to combat drought and flood, but no one systematically integrates the
research on the function of mountain water including rainwater with protecting mountains,
eliminating induced geological disasters, stabilizing water source functions of mountains,
obviating floods originating in mountains, the preserving mountain ecology, and developing
mountain agriculture. Our Suitaiology science uniquely differentiates mountains into small units
to study how rainwater acts on each piece, how its situation is transformed, and how to
systematically and precisely control the situations of mountain waters, so as to provide theories,
methods and technologies for comprehensively securing mountain environment and mountain
agriculture. The water situation refers to the situation and state of the trend of water action,
which is related to the state of water itself, the objects subjected to water action and the
environment, and is a dynamic vector. Mountains are complex and diverse. This speech just
gives a general outline of our research.

What will audience learn from your presentation?
(Try to list 3-5 specific items)
• A systematic concept, principle, approach, and method will help the audience in their job.
• A short-sighted act may cause long-term harm, and the solution of one problem may lead to
another new problem. It is essential to determine the long-term goals, keep a macro mind
overview the related issues which form a system, find the core connection of the problem froma higher perspective than this system, and then use a relatively micro method to conduct in-
depth analysis and implement precise actions.
• Following such a set of research processes, there will naturally be methods and technologies to
solve problems, which are fast and precise, and can prevent other adverse side effects.



Dr. Dachang Zhang received the 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 in 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 released at the 1st Edition of Global Conference on Agriculture and Horticulture (AGRI 2021) in 2021.
