9-6 PREVENTION OF DESERTIFICATION: A DEMONSTRATION PROJECT IN CHINA

9-6


Project Scope and Relationship to China's Agenda 21

Project Scope and Relationship to China's Agenda 21

This project is based on programme areas 16A, 16B, 16C, 14B, 14C, 14D, and 14E of China's Agenda 21. The specific objectives addressed are to establish systems for desert control and prevention, information monitoring systems, and to reduce the expansion of desertification due to human destruction.

1. Background

Desertification is a serious problem in China. It is estimated that about 76.6 million hectares or 8% of the total area are currently affected by desertification. Desertification caused by water erosion accounts for 47.9%, wind erosion for 43.6% and saminization for 8.5%. Another 4.7 million hectares are potentially susceptible to desertification. The problems are concentrated in the agropastoral regions and loess plateau in the arid and semi-arid areas of Northern China, and in the hilly and mountainous regions of southern China, and in the Huanghuaihai Plain region.

The rate of desertification is increasing due to the impact of population growth and human activities, especially in recent decades. The rate of desertification is up to 210,000 hectares per year in Northern China, and 1.0%-1.5% per year in Southern China. Human activities are the dominant causes for desertification. In Northern China, 25.4% of desertification is caused by over-cultivation, 28.3% by over-grazing, 31.8% by denudation, 9.0% by industrial and transportation projects and 5.5% by sand dune encroachment.

In recent decades, research on desertification in China has helped to develop the technical know-how for prevention of desertification and provide information by remote sensing techniques. However, further work is necessary to apply these research findings in practical demonstration areas as well as disseminating the information to those directly affected and those able to implement the required actions. In other words, there is a need for information diffusion and capacity building in affected areas, particularly for applied research and extension activities.

2. Objectives

3. Activities

The implementing agencies of this project will be the State Planning Commission, the State Sciences and Technology Commission, the Chinese Academy of Sciences, and other related agencies.

4. Inputs

5. Benefits

The project will improve research, rehabilitation technologies and management ability of desertification amelioration in China. In a short term, the project will provide valuable information for the national and local economic planning, and demonstration for effective amelioration. In a long term, it will help the sustainable development of the country.

By the year of 2000, the economic benefits from the project includes a reduction of 20% in loss of production from desertification (current levels are about 50 million yuan), and an increase of some RMB 1 billion yuan in regional income.

The project will help develop and disseminate techniques for prevention, control and amelioration at the local and community levels thus helping to build local capacity. At the national level, the project will help decision-making and management departments in the central and local governments. The data bases and management model bases can be connected with those by the National Planning Committee and the Science and Technology Committee, which provide consultation service for the Agriculture Department, Forestry Department, National Environmental Protection Agency and Land Management Agency, and technological service for regional desertification research.

The project will also yield international benefits in sharing information about causes of and trends in desertification and methods of prevention, control and restoration.
