Climate Change, Risk and Grain Yields in China

引用

Journal of Integrative Agriculture 2013年第7期12卷 1279-1291页

作者： Rainer Holst Xiaohua Yu carola Grün Courant Research Center 'Poverty Equity and Growth' Georg-August-University of Goettingen World Bank

Adopting Just and Pope （1978, 1979） style yield functions, this paper proposes a method to analyze the impacts of regional climate change on grain production in China. We find that changes in climate will affect grain production in North and South China differently. Specifically, it emerges that a 1℃ increase in annual average temperature could reduce national grain output by 1.45% （1.74% reduction in North China and 1.19% reduction in South China）, while an increase in total annual precipitation of around 100 mm could increase national grain output by 1.31% （3.0% increase in North China and 0.59% reduction in South China）.

Industrial Structural Changes in Hong Kong,China under One Country,Two Systems Framework

作者： Simon Xiaobin ZHAO carola B RAMóN-BERJANO International Center for China Development Studies & Department of Geography Faculty of Social Sciencesthe University of Hong KongHong KongChina

Hong Kong has undergone substantial economic transformations and developed into a sophisticated busi- ness and financial center in the Asia-Pacific region, since the return of sovereignty to China as a Special Administrative Region under the One Country Two Systems （OCTS） in 1997. This paper discusses and analyzes the industrial struc- tural changes of Hong Kong in recent decades as well as its future challenges and opportunities, The data and finding reveal that even though Hong Kong will face fierce competition from the Mainland＇s cities as the rise of China, the important role as a bridge between China and the rest of the world wilt brace Hong Kong itself under the OCTS for developing into a service hub for business and trade in the Asia-Pacific region.

Southeast Asian primate communities:the effects of ecology and Pleistocene refuges on species richness

We examined historical and ecological factors affecting current primate biodiversity in Southeast *** Africa,Madagascar and South America,but not Southeast Asia,primate species richness is positively associated with average rainfall and distance from the equator(latitude).We predicted that Southeast Asia’s non-conformance may be due to the effect of dispersed Pleistocene refuges(locations of constricted tropical forests during glacial maxima which today are at least 305 m in altitude).Based on 45 forested sites(13 on large islands;32 on the mainland)of at least 100 km^(2) to minimize recent human impact,we determined correlations between extant primate species richness and rainfall,latitude and supplementary ecological variables,while controlling for refuges and *** found that refuge sites had significantly higher primate species richness than non-refuges(t=-2.76,P<0.05),and distance from the nearest Pleistocene refuge was negatively correlated with species richness for non-refuge sites(r=-0.51,P<0.05).There was no difference in species richness between sites on large islands and the mainland(t=-1.4,P=0.16).The expected positive relationship between rainfall and species richness was not found(r=0.17,P=0.28).As predicted,primate species richness was negatively correlated with latitude(r=-0.39,P<0.05)and positively correlated with mean temperature(r=0.45,P<0.05).General linear models indicated that a site’s latitude(F_(1,38)=6.18,P<0.05)and Pleistocene refuge classification(F_(1,42)=5.96,P<0.05)were the best predictors of species *** ecological and historical factors contribute to present day primate species richness in Southeast Asia,making its biodiversity less of an outlier than previously believed.
