加强市县级农业气象业务信息化与自动化建设,可有效提升直通式农业气象服务水平。本文面向基层气象为农服务需求,依托省级农业气象业务服务平台,构建基于Web-GIS市县级农业气象业务服务系统。系统首先应用ArcSDE技术,将省级农业气象业务服务平台输出的农业气象监测、灾害诊断和利弊影响分析等数据产品,转换为空间数据库;采用ArcGIS Server for Flex API开发技术,在浏览器端实现对农业气象数据产品的空间分析。通过拓展省级农业气象周年服务方案、农业气象指标库及农业气象灾害防御对策等知识库,构建农业气象知识库在线维护与服务平台。并基于Internet平台,为县级气象为农服务人员,提供基础数据统计分析及省、市、县三级农业气象业务服务产品共享等功能。系统基于B/S结构,便于推广应用,可为基层直通式农业气象服务提供重要技术支撑。 相似文献
The role of technology in combatting climate change through mitigation and adaptation to its inevitable impacts has been acknowledged and highlighted by the Parties to the United Nations Framework Convention on Climate Change (UNFCCC). In the developing world, this has received particular attention through the technology needs assessment (TNA) process. As Parties put forward their national pledges to combat climate change, the scarcity of resources makes it important to assess (i) whether national processes designed to tackle climate change are working together and (ii) whether existing national processes should be terminated with the initiation of new ones. This study presents an assessment of the existing TNA process and its linkages to the nationally determined contributions (NDCs) under the Paris Agreement. The conclusions stem from an assessment of the TNAs completed to date, as well as 71 NDCs from developing countries at various stages of the TNA process. The analyses show that further developing the TNAs could play a vital role in filling gaps in the existing NDCs, specifically those relating to identifying appropriate technologies, their required enabling framework conditions and preparing implementation plans for their transfer and diffusion.
Key policy insights
The full potential of the TNAs has still to be rolled out in many countries.
Developing countries can maximize the potential of their TNAs by further developing them to explicitly analyse what is needed to implement existing NDCs, including by better aligning their focus, scope and up-to-dateness with the priority sectors included in the NDCs.
Requests of developing countries for international assistance, through technology transfer, will be better guided by the completion of the TNA process.
Policies for strengthening the NDCs will benefit from the results of completed, ongoing and future TNA processes.
Agriculture is responsible for the bulk of Ireland’s greenhouse gas (GHG) emissions. However, the potential to mitigate some of these emissions through the adoption of more efficient farm management practices may be hampered by farmers’ awareness and attitude towards climate change and agriculture’s role in contributing to GHG emissions. This paper presents results from a survey of 746 Irish farmers in 2014, with a view to understanding farmers’ awareness of, and attitudes to, climate change and GHG emissions. Survey results show that there was a general uncertainty towards a number of questions related to agricultural GHG emissions, e.g. if tilling of land causes GHG emissions, and that farmers were reluctant to take action to reduce GHG emissions on their farm. To further explore farmers’ attitudes towards climate change, a multinomial logit model was used to examine the socio-economic factors that affect farmers’ willingness to adopt an advisory tool that would show the potential reduction in GHG emissions from the adoption of new technologies. Results show that farmers’ awareness of human-induced global climate change was positively related to the tool’s adoption.
Key policy insights
Irish farmers are generally not sufficiently aware of the impact of their activities on climate change.
A quarter of farmers believed that climate change will only impact on their business in the long-term; such an attitude may lead to a reluctance amongst these farmers to adopt management practices that reduce GHG emissions.
Awareness of climate change affects positively the adoption of new tools to reduce GHG emissions on farmers’ farms.
IT literacy affects willingness to adopt new tools to address GHG emissions.
Reception of agri-environmental advice can have a positive influence on farmers’ willingness to adopt new GHG emission abatement tools.
Farmers in receipt of environmental subsidies are more likely to adopt new abatement tools, either because they are more environmentally conscious or because the subsidy raised their environmentally consciousness.
Willingness to adopt differs between different farm enterprises; operating dairy enterprise increases the willingness to adopt new advisory mitigation tools.
