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.     

高校图书馆虚拟嵌入事实性主题的信息素养服务模式研究

随着高校图书馆用户信息需求变化趋势呈现学习时空泛在化、知识认知建构制和信息需求多样性特征,逐渐表现出与高校图书馆传统信息素养服务供给模式不匹配或错位,导致服务绩效低下。根据高校图书馆用户信息需求变化趋势特征,针对大学生日常生活和专业学习中的事实性知识获取需求,提出以用户为中心,利用虚拟嵌入平台和支架抛锚兼同级同侪互助教学策略的信息素养服务模式。

高校图书馆基于IC的知识管理与虚拟学习社区融合研究

知识管理与虚拟学习具有相关性与互补性,高校图书馆信息共享空间为知识管理与虚拟学习社区的融合创造了有利条件,因此知识管理与虚拟学习社区的融合是可行的,但是面临来自于观念、技术、功能、内容、交互性等方面的障碍。图书馆应尽可能地采用现代信息技术将知识管理系统与虚拟学习社区集成在一个IC内,进而提升自身的服务水平。

Development of a crop knowledge base for Europe

This paper describes the development of a Crop Knowledge Base System for use in crop modelling and yield forecasting. The inherent limitations of databases can cause problems for dealing effectively with geo-referenced data sets. The system described here includes all the normal database operations but also handles richer types of data. Values of queried attributes can be deduced through the use of heritability within hierarchies and by the application of rules that summarise sets of empirical observations. The system is able to reason about similar locations, so that where no information exists in the knowledge base for a particular location, then an alternative location, subject to similar meteorological and agricultural conditions, will be sought.     

Public perceptions of natural disturbance in Canada’s national parks: The case of the mountain pine beetle (Dendroctonus ponderosae Hopkins)

Since the 1990s, the mountain pine beetle (MPB) population has exploded in western Canada. In national parks, MPB has the potential to impact visual quality and safety of visitors, and to spread beyond park boundaries to the industrial forest landbase. Control measures have been initiated in some parks to lessen these impacts. A study was undertaken to examine public attitudes, knowledge, issue salience, and management preferences for MPB in Banff and Kootenay national parks. Data were collected by mail survey in 2003 from 1385 residents living in or near the parks. MPB was an important issue for the majority of respondents and they had low knowledge of MPB, expressed negative attitudes towards it, and supported measures to control it. Preferred control measures included those directed at the current infestation. Proactive approaches in uninfested forests were generally not supported. Issue salience and knowledge were the best predictors of attitudes toward the MPB. Attitudes were the best predictors of support for no intervention in beetle infestations in national parks. Management implications include the lack of knowledge and support for natural disturbance and ecological integrity policies in national parks.
