The first ―International symposium on Soil Erosion and Dry-land Farming‖ was held in
September of 1997. More than 150 participants from 28 countries attended this meeting.
Participants shared experiences, accomplishments, and issues in soil erosion management and
dry-land farming. With increasing concerns of the effects of global climate change on food
and fiber production, new questions and challenges have arisen concerning our ability to
sustain our limited land and water resources. In recent years, prolonged drought and frequent
flooding have been attributed to global climate change and the deterioration of the
environment. On the Chinese Loess Plateau, for example, a sustainable agriculture is being
challenged by limited water resources, severe erosion and drought. How to balance and
harmonize economic development and environmental protection in resource-limited areas is
becoming a world-wide concern. Whether current conservation practices and farming
techniques can provide food security under increasing population, diminishing resources and
climate instability needs to be addressed. This symposium provides an opportunity for
scientists world-wide to share their experiences, progress made, and achievements in soil
erosion/conservation and dry-land farming in past years. Specifically, the Symposium will
address the following.

   To share and exchange the experiences, progresses made and achievements in soil erosion
    and dry-land farming.
   To promote new knowledge about controlling soil and water losses and providing food
   To show new technologies in soil conservation and dry-land farming.
   To develop long-term strategies and partnership for scientific cooperation.

   Soil erosion processes, assessment, and control
   Mechanism and techniques of ecological rehabilitation
   Sustainable soil and water resource management in semi-arid areas
   Improved water use efficiency in dry-land farming systems
   Impacts of global climate change on soil erosion and dry-land farming
   New technologies in soil conservation and dry-land agriculture

                                 General Introduction of Yangling

      More than 4000 years ago, it was here in Yangling that Houji-agricultural ancestor of the Chinese
nation taught the people how to grow crops and to learn cultivation techniques of five cereals and
established a precedent of the Chinese farming civilizations.
     In 1934, it was here in Yangling that Mr. Yu Youren and General Yang Hucheng, et al. initiated to
establish the earliest agricultural institution of higher learning -"the National Northwestern Faculty of
Agriculture and Forestry" in the northwestern areas in China.
     In July 1997, approved of by the state council, Yangling became only one of National Grade of
Agriculture High-Tech industry demonstration Zone.
     In July 2000, Yangling Demonstration Zone was approved of by the state as the open-up sci-tech
industrial park for China to Asia-Pacific Economic Cooperation (APEC).
     Yangling Demonstration Zone covers a total areas of 94 km2, and under its jurisdiction, there is
Yangling district (county level), with a total population of 136,000. The planned area of the
newly-constructed zone is 22.12 km2, consisting of such 7 functional districts as agro-science garden
district, modern agricultural and rural construction demonstration garden district, agricultural high-tech
industrial garden district, agricultural comprehension garden district, agricultural intermediate experiment
garden district, living service garden district and agricultural sight-seeing and recreation belt, etc.
     Yangling Demonstration Zone enjoys each item of preferential policies set for national high-tech
industrial development zones at the state level and the policies inclining to and backing agriculture as well
as each item of preferential policies set for developing the western areas in China. The administrative
Committee of Yangling Demonstration Zone is the agency under the direct levels and provincial economic
management right as well as part of provincial administrative right.
     For 7 years since its establishment, Yangling Demonstration Zone has developed so rapidly that the
fixed asset investments completed have been 1.56 billion RBM yuan. The synchronous development of
high-tech industries and infrastructure construction has been on the high starting point and high standard
requirements in construction. Accordingly, Water Sports Center, Yangling International Exhibition and
Convention Center, Thermal Power Plant and Yangling Information Port with highly speed breadth bands,
etc. have been completed in succession so that the city framework has been initially formed. Also, a batch
of the important high sci-tech projects with the international advanced standards, and having
self-independent intellectual properties have settled in Yangling one after another so that an industrial
pattern with the fine crop variety and animal breed breeding, manufacturing of water-saving irrigation
equipment, bioengineering, pharmaceutical production, agriculturally-used chemical industry and
agro-production, agro-products integrated processing as the representative undertakings has been initially
formed. As a result, eco-city and industrial city with functions of having innovation spirit and bringing
about the motivation, radiation and demonstration is gradually being turned into reality in this beautiful
environment with complete functions and full of business opportunities.
