Improving technology transfer through national systems of innovation: climate relevant innovation-system builders (CRIBs)     

David Ockwell  Rob Byrne 《Climate Policy》2016,16(7):836-854

The Technology Executive Committee (TEC) of the United Nations Framework Convention on Climate Change (UNFCCC) recently convened a workshop seeking to understand how strengthening national systems of innovation (NSIs) might help to foster the transfer of climate technologies to developing countries. This article reviews insights from the literatures on Innovation Studies and Socio-Technical Transitions to demonstrate why this focus on fostering innovation systems has potential to be more transformative as an international policy mechanism for climate technology transfer than anything the UNFCCC has considered to date. Based on insights from empirical research, the article also articulates how the existing architecture of the UNFCCC Technology Mechanism could be usefully extended by supporting the establishment of CRIBs (climate relevant innovation-system builders) in developing countries – key institutions focused on nurturing the climate-relevant innovation systems and building technological capabilities that form the bedrock of transformative, climate-compatible technological change and development.

Policy relevance

This article makes a direct contribution to current work by the TEC of the UNFCCC on enhancing enabling environments for and addressing barriers to technology development and transfer (specifically, it will contribute to Activity 4.3 of the TEC's 2014–15 rolling workplan ‘Further work on enablers and barriers, taking into account the outcomes of the workshop on NSIs’). The article articulates both the conceptual basis that justifies a focus on NSIs in relation to climate technology transfer and makes concrete recommendations as to how this can be implemented under the Convention as a Party-driven extension to the existing architecture of the Technology Mechanism.  相似文献   

基于多视图协同的时空数据可视分析方法     

刘明超  吴升  余劲松弟 《测绘科学技术学报》2017,34(2)

针对时空数据可视分析中存在的问题,提出了由可视分析模型(VAM)和交互协同模型(ICM)组成的多视图协同可视分析模型,将可视分析过程划分为数据变换、数据分析、可视映射和可视绘制4个过程;以可视分析过程中的参数作为协同主题,利用观察者模式,实现关联视图在交互过程中的协同一致;设计了Web环境下,基于"图数协同"和"图图协同"交互模式的多视图协同可视分析架构;构建了犯罪时空数据可视分析原型系统,并利用系统分析了福州市扒窃案的时空分布规律,对涉案价值较高的扒窃案进行了犯罪模式分析。  相似文献

Climate variability and tropical tuna: Management challenges for highly migratory fish stocks     

Kathleen A. Miller 《Marine Policy》2007

The 1995 United Nations Fish Stocks Agreement facilitates the creation of regional fishery management organizations (RFMOs) to govern harvests of straddling and highly migratory fish stocks. The stability and success of these organizations will depend, in part, on how effectively they can maintain member nations’ incentives to cooperate despite the uncertainties and shifting opportunities that may result from climate-driven changes in the productivity, migratory behavior, or catchability of the fish stocks governed by the RFMO. Such climatic impacts may intensify incentives for opportunism, and create other management challenges for the RFMOs now governing tropical tuna fisheries in the Pacific and Indian Oceans.  相似文献   

Governmentality and the climate-development nexus: The case of the EU Global Climate Change Alliance     

《Global Environmental Change》2019

This article uses a governmentality perspective to uncover the power effects of the external climate change adaptation assistance provided by the European Union (EU) through its flagship initiative in this regard: the Global Climate Change Alliance. By drawing upon a body of literature that conceptualizes the established international architecture in this regard as rooted in power relations, this article opens up our current perspective of the EU as an international climate actor. An analysis of policy documents and targeted semi-structured interviews reveals that the EU discursively emphasizes the responsibility of partner countries to manage risk and become ‘resilient’ to climate impacts, while downplaying the transformative potential of adaptation for development. We see this dynamic further reflected in GCCA policy techniques, which promote the production of quantified and depoliticized knowledge on adaptation. This in its turn further guides the allocation of GCCA support and is instrumentalized in order to establish a stable identity for the organization and reproduce the EU as a climate leader in this regard.  相似文献

Expert System for Statistical Prediction of Mineral Deposits on Middle and Large Scales     

Zhao Pengda Hu Guangdao Li XinzhongFaculty of Mineral Resources  China University of Geosciences  Wuhan 《中国地质大学学报(英文版)》1995,(2)

The expert system for statistical prediction of mineral deposits on middle and large scales takes the system of scientific exploration theories, criteria and methods proposed by Professor Zhao Pengda as the field expert knowledge. At present the developed system focuses on two aspects: synthetic exploration and quantitative exploration. Among the three basic theories for the prediction of deposits, it highlights the applications of seeking anomaly theory. This system is characteristic in the determination of geological background, the study of geological anomalies and the delineation of geological background, the study of geological anomalies and the delineation of mineralization anomalies. The system combines closely the knowledge base, method base and database ,integrates the input and output information of multi-sources and multi-variables, data , graphs and imagine processing system and inquiring system as a whole . So the system can meet in general all kinds of demands in statistical prediction of m  相似文献
