    Land use change resulted in land degradation is a focus of research on global environmental changes and plays a significant role in the stability and economic development of oases in arid regions of China. Jinta Oasis, a typical oasis of temperate arid zone in northwestern China, was investigated to assess land-use change dynamics during 1988-2003 with the aid of satellite remote sensing and GIS, and to explore the interaction between these changes and oasis environment.

    This paper presents a macro-micro analysis of the impact of policy reforms in China on agricultural production, input use and soil quality change for a major rice-producing area, namely Jiangxi province. This is done in three steps. First, a quantitative assessment is made of the impact of market liberalization policies on the economic environment of farm households in Jiangxi province. Econometric analyses based on provincial, national and world market data are used to explain changes in rice and fertilizer prices in Jiangxi province over time.

    As a global and regional environmental problem, desertification assessment is an instrumental component in developing global/regional actions plans aimed at preventing and/or eradicating desertification issues. Using a landscape assessment approach allows for relatively quick assessments of desertification that can then be used in developing practicable application plans at the regional level in desertification prevention planning and decision-making.

    Japon

    Japan, with a population of about 125 million, is a major importer of agricultural products. Japan's mountainous topography limits the area available for farming, with a total cultivated land area of around 4.8 million hectares. Farm holdings are small, averaging just over 1.5 hectares.Japan has producer support levels among the highest in OECD, driven in part by food security concerns and memories of food shortages during World War II and its aftermath.

    Our aim was to produce a uniform 'regional' land-cover map of South and Southeast Asia based on 'sub-regional' mapping results generated in the context of the Global Land Cover 2000 project. The 'region' of tropical and sub-tropical South and Southeast Asia stretches from the Himalayas and the southern border of China in the north, to Sri Lanka and Indonesia in the south, and from Pakistan in the west to the islands of New Guinea in the far east. The regional land-cover map is based on sub-regional digital mapping results derived from SPOT-VEGETATION satellite data for the years 1998-2000.
