Status and Trends in Land Degradation in Asia

Abstract

Land degradation is a universal problem; it has cumulative effects at regional and global scales. This paper, based on the 500-meter resolution satellite image (band 1∼7), which was acquired in 2003, and the correlative statistical data, examines the status of land degradation and desertification in the Asian Region. The perspective trends of land degradation are analyzed and indicated. The primary purpose of this study was to assess the major causes of land degradation and desertification in Asia, to suggest procedures and methods for combating desertification and mitigating the effects of land degradation and promote sustainable development.
