Regional Agricultural Drought Adaptation and Its Policy-driven Forces in Agriculture-pasturage Ecotone of Northern China

1. Yanyu YIN School of Geography ， Beijing Normal University Key Lab of Regional Geography 2010.05.31 Regional Agricultural Drought Adaptation and Its Policy-driven Forces in Agriculture-pasturage Ecotone of Northern China —— Taking Xinghe County in Inner Mongolia as an Example

2. Contents 1. Introduction 2. The models for drought adaptation formed in the long historical periods in the agriculture-pasturage ecotone 3. The drought adaptation strateg ies adopted yet in agriculture-pasturage ecotone 4. Case study in X inghe C ounty , Inner Mongolia, China 5. Conclusions

5. (Fu Zongbin,Ma Zhuguo, 2008) 1.2 Aridification in northern China puts forward the urgent need to develop the drought adaptation ability the global climate change has posed Northern China an obvious drought tendency.

6. In the arid and semi-arid climate type areas, Frequent drought, almost once every year. People who live here have developed a successful survival strategies to adapt to the frequent drought. 1.3 the agriculture-pasturage ecotone in northern China (Fu Zongbin,Ma Zhuguo, 2008) Fig the variation the extreme drought events frequency during 1950-2002 Fig the location of agriculture -pasturage ecotone of northern China

7. R researches on the drought adaptation of the drought-prone areas and explore the driving forces background will help to build a better adaptive strategy to coop with the increasingly obvious situation of warming and drying trend in northern China. Of course, drought adaptation is influenced by many factors. This study tries to probe into the problems in policy-driven forces of drought adaptation and takes a pilot study on the policy strategy of drought adaptation in Xinghe County of northern China, in order to provide experience and guidance for Chinese to equip them better to adapt the warmer and dryer climate.

8. 2 . the models for drought adaptation of the agriculture-pasturage ecotone in northern China in historical periods The modern demarcation line of the monsoon region and the non-monsoon region The demarcation would change along with the strength of the monsoon and its impacts. So the precipitation varies a lot in different time. Shi peijun et al(1989) Modern Location covers the ecotone between the farming area of northeast and north China, and pastoral areas of natural grassland ecotone in northwest. Physical conditions in the tail-end of monsoon , 250-300mm, uneven distribution of precipitation in time and space scale With lots of ecological security problems, is a weak strip

13. 4 . Case study: agricultural drought adaptation policy-driven analysis in Xinghe county Xinghe county is located in the middle of agriculture-pasturage ecotone of northern C hina, is a typical rain-fed agricultural areas with more than 90% of its arable land are dry land .

16. Land use structure adjustment Ecological status markedly improved Liberate the labor force engaged in agricultural production Industrial structure adjustment Planting structure adjustment Income structure adjustment Increase the income of household Increase the yield of the crop Decrease the drought vulnerability and the loss due to drought There are complex interactions between those drought adaptation strategies and even the effects of theirs. It is hard to identify the contribution to the drought adaptation on earth.
