Participatory GIS for strengthening transboundary marine governance in SIDS

In this paper we explore the challenges involved in engaging the full range of stakeholders needed for effective marine resource management in the transboundary Grenadine Islands shared by the small island developing States (SIDS) of Saint Vincent and the Grenadines and Grenada. The study describes the ways stakeholders were engaged in the development of participatory geographic information systems (PGIS), both in terms of the research approach (process) and the final geodatabase (product); it illustrates how the approach provides a practical means to strengthen aspects of marine governance, particularly in a SIDS context. We found that PGIS can provide a foundation for ecosystem‐based transboundary marine governance. The advantages of this approach are two‐fold: it provides the fullest possible range of information as input for the management of marine resources and it engages the stakeholders. This engagement takes several forms: capacity to participate in research; ownership of information produced; increased stakeholder understanding; empowerment through access to information; capacity to interact with other stakeholders for information and problem‐solving; and competence to participate in actual governance processes. Lastly, we discuss considerations for other practitioners contemplating using PGIS, particularly those working in similar resource‐limited SIDS environments.     

New tools in local energy planning: experimenting with scenarios,public participation and environmental assessment

This article presents a model for local energy planning and its application in a full-scale experiment in a Swedish municipality. The model is based on legal requirement, research findings and standards of good practice and includes a combination of analytical and procedural tools intended to support rational decision-making: external scenarios, a citizens’ panel, life cycle analysis and qualitative environmental assessment (EA). The application of the model indicates that the decision-support tools selected can give several new and valuable inputs to local energy planning, such as local knowledge and values through citizen dialogue and comprehensive EAs. However, the experiment also shows that there are several challenges involved in applying the tools, for example, it is difficult to get citizens and the industry to participate and that it is complicated to combine several different tools for decision-making into a single planning process. Moreover, the experiences from the application suggest that the model for local energy planning show great potential but needs to be improved before it can be used as a standard of good practice.     

Closing the knowledge-action gap in conservation with open science

The knowledge-action gap in conservation science and practice occurs when research outputs do not result in actions to protect or restore biodiversity. Among the diverse and complex reasons for this gap, three barriers are fundamental: knowledge is often unavailable to practitioners and challenging to interpret or difficult to use or both. Problems of availability, interpretability, and useability are solvable with open science practices. We considered the benefits and challenges of three open science practices for use by conservation scientists and practitioners. First, open access publishing makes the scientific literature available to all. Second, open materials (detailed methods, data, code, and software) increase the transparency and use of research findings. Third, open education resources allow conservation scientists and practitioners to acquire the skills needed to use research outputs. The long-term adoption of open science practices would help researchers and practitioners achieve conservation goals more quickly and efficiently and reduce inequities in information sharing. However, short-term costs for individual researchers (insufficient institutional incentives to engage in open science and knowledge mobilization) remain a challenge. We caution against a passive approach to sharing that simply involves making information available. We advocate a proactive stance toward transparency, communication, collaboration, and capacity building that involves seeking out and engaging with potential users to maximize the environmental and societal impact of conservation science.

基于气象灾害预报的作物种植类型决策方法

干旱、雨涝是农业生态方面重要的水文气象灾害,科学地根据水文气象预报来选择种植作物品种,一直是农业管理者、生产者非常关心的问题,传统的决策方法是根据农业总体区划、作物种植习惯和耕作习惯确定的,具有一定的局限性。提出了基于气象灾害预报对错概率的作物种植类型决策新方法,综合考虑了农业气象预报的误报概率和作物适应性,克服了传统方法的不足。对绥棱农场某种植区20年的水文气象资料进行了分析,计算了旱涝预报与实况联合概率矩阵,推导出水文气象预报对错概率矩阵;根据作物品种在不同天气状况的产量,确定了决策失误损失矩阵。实证分析表明,所提决策方法可有效地减少因旱涝灾害给粮食产量带来的损失,对作物品种的选择具有很好的实用参考价值。     

基于博弈论的安全决策信息融合

安全信息融合的研究涉及多源信息的表示、内在联系和运动规律的研究。冗余和互补的多源信息在融合系统中不可避免地存在着相互竞争和协同作用,因而多源融合系统中的信息冲突与合作的分析成为信息融合理论研究中的核心与实质问题。博弈理论对冲突和合作局势分析与研究提供了一种定量工具,其研究成果成功地解释了多局中人在“交互决策”过程如何构造博弈的“均衡点”,以及“均衡点”所具有的各种特性。笔者在研究了博弈理论的基础上,以博弈论的观点和方法解决安全信息融合系统冲突信息环境下的融合系统决策问题,并建立了相应的模型并应用了融合算法。
