Assessment of the agricultural sustainability of Shaanxi Province,China

It is significant for the study on the sustainable development of regional agriculture to monitor and measurethe trend of agricultural development with an effective method. The sustainable development of regional agricultureshould accord with regional population, rural economic development, social progress, resource and environmentalsupport. This paper establishes the evaluating indicators system of sustainable development of regional agriculture,evaluates the agricultural sustainable development in Shaanxi Province with a comprehensive multi-indicator method,analyzes the support of resource and environment for regional agriculture by the resource-development index and theenvironment-development index, and gets the conclusion that the indicators, such as education level, the income gapbetween urban and rural residents, the per capita area under cultivation and the consumption of pesticides and chemicalfertilizers per hectare, are the main factors to restrict agricultural sustainability, and that the pressure of the developmentof subsystems of population, economy and society on the subsystems of resource and environment turns out to bestronger and stronger. Agricultural environment gets better, but resource becomes one of the important factors to restrictthe development of regional agriculture. In a word, this paper highlights the potentials and limitations of sustainableagriculture of Shaanxi and helps identify the development direction in the future.

Linking scenarios across geographical scales in international environmental assessments

The development and analysis of scenarios or plausible futures has evolved to be a useful approach for dealing with uncertainty about future developments in a structured and integrated manner. Commonly, scenario exercises have focussed on processes at one specific geographic scale. Recently scenario-based approaches have also been used to address multi-scale processes or to link scenarios developed at various geographical scales with each other in order to better understand the interaction of processes across scales.The level of interconnectedness across scales will vary, and depends largely on the approaches used to develop multi-scale scenarios. We distinguish five levels of interconnectedness scenarios may display across scales: (a) Equivalent, (b) Consistent, (c) Coherent, (d) Comparable, and (e) Complementary. Furthermore, we describe five different types of coupled scenario development processes: (a) Joint, (b) Parallel, (c) Iterative, (d) Consecutive, and (e) Independent.Based on this nomenclature, the relationship between the level of interconnectedness of scenarios and the degree of coupling of scenario development processes across geographical scales is discussed. Which process is best suited and how much interconnectedness is needed, will depend both on the focal issue and the primary purpose of the scenario exercise, i.e. whether the aim is education, scientific exploration, or decision-support.

Study on the clustering of a typical industry：a case of apple industry in Shaanxi Province, China

The apple industry in Shaanxi Province is a resource-based industry; compared to the best productiveregions at home and abroad, it is advantageous in high quality as well as geographical and natural resources. Currently,big changes have occurred in the apple market supply-demand relations; long-term and comprehensive shortage haspassed; the buyer＇s market has come into being; competitions in the domestic market are fierce. At the same time, theforeign apple will impact on the domestic market, increasing competitive pressure. Foreign anti-dumping measures,green barriers and technologies restrict the exportation of the domestic apple. Based on successful experience of otherindustrial clusters, this paper analyzes the existing problems in the development of Shaanxi apple industrial cluster,combining empirical analysis, qualitative analysis and quantitative analysis, proposes specific policy recommendationsand get the conclusions. First, the characteristics of the agricultural industrial cluster are analyzed; Shaanxi appleindustry is characterized by cluster. Second, the rapid development of Shaanxi apple industrial cluster exposes someproblems. Third, we need the government to control the disorderly competition of Shaanxi apple industry.
