林业电子政务信息系统企业架构框架总体设计

该文设计了6层林业电子政务企业架构框架静态模型FSM,以及FSM各层次中包含的参考模型,这些参考模型可用于描述构建林业电子政务信息系统的方法、技术标准规范和用于交互的信息。FSM各参考模型中包含的信息被存储在数据库中并通过网络发布,以便各林业管理机构能够共享企业架构信息。该企业架构设计可以帮助决策者对IT项目进行选择,对IT投资进行评估;能够帮助林业管理机构实现软件重用,进而降低系统TCO;能够帮助林业管理机构实现机构之间的互操作性或信息共享。

国土空间生态修复关键区域系统识别与修复

基于生态系统问题诊断与生态安全格局构建,探索国土空间生态修复关键区域识别与修复的方法路径。以武汉市蔡甸区为研究区域,从数量、质量、空间格局等3个方面系统诊断了生态系统的退化程度、退化类型及其空间分布。基于生态源地的识别,并以土地覆盖类型、距离水源距离、植被覆盖度、坡度、高程等5种因子构建生态阻力面,通过最小阻力模型识别潜在生态廊道,进而构建生态安全格局。在此基础上,综合生态系统问题诊断与生态安全格局需求,系统地辨识出了武汉市蔡甸区的生态保育区、自然修复区、人工修复区和生态廊道建设区。结果显示,共提取出1 901.52 hm²林地和水体作为生态源地,识别出18 168.12 m潜在生态廊道。从生态保育、自然修复、人工修复、生态廊道建设4个方面提出了对应的生态保护修复措施。     

Networking of integrated pest management: A powerful approach to address common challenges in agriculture

Integrated pest management (IPM) is facing both external and internal challenges. External challenges include increasing needs to manage pests (pathogens, animal pests and weeds) due to climate change, evolution of pesticide resistance as well as virulence matching host resistance. The complexity of designing effective pest management strategies, which rely less heavily on the use of conventional pesticides, is another external challenge. Internal challenges include organizational aspects such as decreasing trend in budget allocated to IPM research, increasing scarcity of human expertise, lack of knowledge transfer into practice and the communication gap both at country level and between countries, and lack of multi-, inter- and transdisciplinary IPM research. There is an increasing awareness that trans-national networking is one means to overcome such challenges and to address common priorities in agriculture. A large number of stakeholders (researchers, policy makers, growers and industries) are involved in the sector of crop protection, which needs to be coordinated through effective communications and dynamic collaboration to make any IPM strategy successful. Here we discuss a decade-long IPM networking experiences in Europe emphasizing how IPM research, implementation and adoption in Europe may benefit from a broader level networking.     

The routes to fruit: Governance of urban food trees in Canada

Interest in planting urban food trees (UFTs) in public spaces is growing in popularity as a form of urban greening and a potential food source. Currently there is minimal research on the governance and policy aspects of integrating food trees into cities. To fill this gap, we investigated the characteristics of UFT site governance and how it compares to current urban forest governance. Semi-structured interviews were conducted with relevant municipal officials in Calgary, Edmonton, Toronto and Victoria about their perspectives and involvement with UFT sites in their city. A scan of policy documents was completed to supplement the interviews. The interviews were analyzed using a deductive coding framework based on the Policy Arrangement Approach. We found that key actors at the UFT sites were local organizations and site champions, with minimal municipal engagement. Most site resources provided by municipalities were in-kind. There are also basic knowledge gaps about how to care for UFTs. Currently municipal by-laws prohibit the harvesting and removal of plant material, and are at odds with the purpose of UFT sites, with few municipalities fully integrating UFTs in policies. The primary discussion around UFTs centre concerns for public health and safety, management, and use of public space with limited discussions of benefits. This research demonstrates the value of co-governance models to support UFTs, while a shift in focus from risks to benefits could encourage additional resources and policy integration. Further, including UFTs into policy would also support foraging and food tree maintenance in public spaces, and more fully reflect the plurality of urban forest engagement.
