Climate policy networks in South Korea: alliances and conflicts

A policy network analysis using a questionnaire survey was conducted to identify the main climate policy actors in South Korea and examine how they form alliances and come into conflict over four major issues. Generally, it was found that governmental organizations are the main actors in the South Korean climate policy arena and that they mediate between the business and civil sectors. In particular, key organizations in each sector play a leading role in the formation and maintenance of at least two distinct alliance networks: growth and environmental. In particular, the growth network has been stronger and more intense than the environmental network, with the exception of nuclear power policy. The crucial drivers of proactive policy discourse in South Korea have been scientific discourse and a consensus on the advent of anthropogenic climate change by the international scientific community, the international climate change negotiations and the pressure to commit to GHG emissions reduction, and low-carbon green growth strategy.

Policy relevance

The positions of South Korean governmental organizations (as well as other civil society organizations) on the four major issues of climate policy have not been aligned. The government has not acted as a unified body; instead it is an aggregated body composed of organizations with competing interests. If policy actors with different interests share the recognition of the state of the country within global society and understand international pressure as well as the urgency of combating climate change, then a common policy goal can be achieved. It is essential for the government to exert proactive leadership for climate policies in mediating the growth and environmental networks. It is important to boost environmental networks in order to overcome the alliance of growth networks. A more proactive response for combating climate change would establish open policy-making processes for environmental network actors and provide economic opportunities for climate actions.     

福建省县域可持续发展水平空间格局与动态变化研究

通过构建福建省县域可持续发展水平的评价指标体系并收集相关数据,采用主成分分析、方差分析与加权移动平均等方法对2003-2008年福建省县域可持续发展水平空间格局与动态变化进行分析。结果表明:1)福建省县域可持续发展水平整体两极分化明显,且两级差距扩大;高发展水平的县域间差异显著,而低发展水平的县域间差异不明显。2)福建省可持续发展空间格局由"沿海一级长轴"、"西部二级短轴"及广大低水平区域构成。"沿海一级长轴"范围稳定,等级结构优化;"西部二级短轴"范围变小,等级稳定,可持续发展水平空间不平衡有所减弱。3)在海峡西岸经济区建设过程中,应基于福建省可持续发展水平和空间特征,促进闽台多层次和全方位的分工与合作。     

不同深度围岩力学行为对矽卡岩型矿床成矿作用的影响——来自长江中下游成矿带龙角山钨矿床的证据

目前矽卡岩矿床的研究对象主要集中在成矿岩体和矽卡岩矿物,相对而言,控制矽卡岩矿床形成的另一个重要端员围岩的研究则明显薄弱。已有研究表明,不同深度围岩岩石力学性质决定了围岩在外力作用下发生形变的方式及规模,但仅限于定性研究,定量围岩力学性质研究及其对成矿作用制约则尚未开展。本文以长江中下游成矿带典型矽卡岩型钨矿床——龙角山矿床为研究对象,通过三轴压缩试验系统测定了不同赋矿深度围岩地层和成矿岩体的力学性质,探讨了不同深度围岩的力学行为及其对成矿作用的影响。灰岩的弹性模量E随深度增加呈现先降低再增加后降低的趋势,灰岩的三轴相对强度S随着深度增加呈现先增加后降低趋势。灰岩的硬化模量H和跌落模量M随深度的变化呈现非线性趋势,而花岗岩的弹性模量E、三轴相对强度S、硬化模量H和跌落模量M均呈现随深度增加而增加的趋势。灰岩的两类峰前塑性指标随深度的变化呈现先降低再增加后降低的趋势,可知地应力和矿物组分对灰岩的塑性特征影响存在博弈作用。不同深度的灰岩峰后塑性指标随深度的变化迥异,其中B_resStress和B_resStrain具有反向协同性,整体显示了灰岩具有脆...

Academics among farmers: Linking intervention to research

Geographers and other academics whose reputations and advancement depend on their work among developing country farmers have an obligation to assist the farmers in tangible ways. A project of the United Nations University which did this in 1993-2002 (PLEC)is described, with particular reference to Ghana, together with a follow-up project in the same country. Best methods of resource management were sought among the farmers themselves, and expert farmers were encouraged to instruct others in their methods. Moreover, in a project concerned with the conservation of biodiversity on farm, the farmers were also assisted in enterprises creating added value from biodiversity. Getting behind the farmers in their own enterprises can enrich academic research.
