Sustainable Rangeland Management in Southwest Iran: Understanding Changes in Experts’ Attitudes Toward Livelihood Alternatives

The importance of knowledge sharing, as an integral part of decision making, has been highly acknowledged by many authors. However, the process in which knowledge sharing should be conducted has remained a debatable issue. In this study, changes in experts’ attitudes, as a result of the knowledge-sharing process, in the context of rangeland management were assessed. We demonstrated a three-step knowledge-sharing process while recognizing collaborative knowledge sharing systems, which involves knowledge-sharing tools including face-to-face and virtual approaches. The process was applied to explore experts’ attitudes regarding livelihood alternatives in the Bazoft region of southwestern Iran. Sixty experts were selected from three groups categorized as key local stakeholders, practitioners, and scientists. First, the experts were independently given the task of ranking livelihood alternatives. Next, for a better understanding of alternatives and enhancing their view, additional knowledge and information were provided. Thereafter, their attitudes in the final step were assessed. According to the findings, change in the experts’ attitudes could take place, which eventually resulted in the prioritization of livelihood alternatives to approach sustainable rangeland management (SRM). The synergy of experts’ knowledge, which can be realized through a collaborative knowledge sharing process, can be further pursued by devising a workable policy framework to approach SRM.

基于农业时空多模态知识图谱的水稻精准施肥决策方法

为构建基于农业时空大数据的管理系统，实现田间养分精细化管理，提出了一种面向精准施肥的农业时空多模态知识图谱的构建及其控制与决策方法。通过基于深度学习的子图匹配方法，将地块待查询图和农业时空多模态知识图谱中的节点和关系嵌入表示；利用向量相似度计算获取候选子图，并从存储历史数据信息的子图中获取适合查询地块的施肥模型数据。结果显示，基于实例化后的待施肥地块查询图，在农业时空多模态知识图谱中可获取与给定地块查询图同构的子图，并从存储历史决策信息的子图中，获得适合当前地块的农业施肥模型。结果表明，基于农业时空多模态知识图谱的农业模型自动化选择结果可为精准施肥任务提供新思路和决策支撑。
