Adaptive management of natural resources--framework and issues

Adaptive management, an approach for simultaneously managing and learning about natural resources, has been around for several decades. Interest in adaptive decision making has grown steadily over that time, and by now many in natural resources conservation claim that adaptive management is the approach they use in meeting their resource management responsibilities. Yet there remains considerable ambiguity about what adaptive management actually is, and how it is to be implemented by practitioners. The objective of this paper is to present a framework and conditions for adaptive decision making, and discuss some important challenges in its application. Adaptive management is described as a two-phase process of deliberative and iterative phases, which are implemented sequentially over the timeframe of an application. Key elements, processes, and issues in adaptive decision making are highlighted in terms of this framework. Special emphasis is given to the question of geographic scale, the difficulties presented by non-stationarity, and organizational challenges in implementing adaptive management.     

Adaptive management for a turbulent future

The challenges that face humanity today differ from the past because as the scale of human influence has increased, our biggest challenges have become global in nature, and formerly local problems that could be addressed by shifting populations or switching resources, now aggregate (i.e., "scale up") limiting potential management options. Adaptive management is an approach to natural resource management that emphasizes learning through management based on the philosophy that knowledge is incomplete and much of what we think we know is actually wrong. Adaptive management has explicit structure, including careful elucidation of goals, identification of alternative management objectives and hypotheses of causation, and procedures for the collection of data followed by evaluation and reiteration. It is evident that adaptive management has matured, but it has also reached a crossroads. Practitioners and scientists have developed adaptive management and structured decision making techniques, and mathematicians have developed methods to reduce the uncertainties encountered in resource management, yet there continues to be misapplication of the method and misunderstanding of its purpose. Ironically, the confusion over the term "adaptive management" may stem from the flexibility inherent in the approach, which has resulted in multiple interpretations of "adaptive management" that fall along a continuum of complexity and a priori design. Adaptive management is not a panacea for the navigation of 'wicked problems' as it does not produce easy answers, and is only appropriate in a subset of natural resource management problems where both uncertainty and controllability are high. Nonetheless, the conceptual underpinnings of adaptive management are simple; there will always be inherent uncertainty and unpredictability in the dynamics and behavior of complex social-ecological systems, but management decisions must still be made, and whenever possible, we should incorporate learning into management.     

中国流域水资源生态补偿的法律问题与对策

随着我国经济社会的不断发展,水资源不足和水质污染引起的水危机已经成为许多地区可持续发展中的重要制约因素。在这种背景下,为了平衡环境、社会和经济多元利益,寻求先进的法律机制来调节平衡、保护流域生态环境、促进流域的可持续发展已成为一种共识。开展流域水资源生态补偿是实现流域上下游之间等相关方利益公平的关键所在。但由于我国缺乏生态补偿立法和相应的制度安排,流域水资源生态补偿目前仍面临许多问题：我国流域水资源生态补偿进展缓慢、法律制度滞后、部分法律法规彼此之间矛盾和相互冲突、流域水资源生态补偿的法律制度缺位、立法模式不适合当今流域生态环境问题解决等。本文通过对我国有关涉水法律中存在问题的分析,提出一些有关流域水资源生态补偿法律制度建设和完善的对策,以期对中国流域水资源生态补偿的推进和进一步实现水资源的可持续利用有所帮助。     

中央—地区二元结构的煤炭城市可持续发展战略选择与路径

煤炭在未来相当长的时间内仍是我国的基本能源。构建了中央—地区二元结构的煤炭城市可持续发展战略匹配集,根据煤炭资源的开采程度将煤炭城市分成幼年期、成长期、成熟期、衰退期四个阶段,基于三维综合判断对不同阶段的煤炭城市提出了不同的战略选择,明晰了不同发展战略的战略目标及发展的支持性政策措施。     

煤矿安全管理要素探讨

通过对煤矿安全管理要素的分析强调了以人为本的安全管理思路,针对目前煤矿安全管理中存在的一些误区,结合企业实际和其它煤炭企业管理经验,以及安全管理要素相互作用的理论,提出了以＂人＂为本、以＂物＂保＂人＂、以＂环境＂影响＂人＂的管理方法和工作措施。     

煤工尘肺患者生存质量与家庭功能和社会支持的关系研究

为了解煤工尘肺患者的生存质量的现状及其与家庭功能和社会支持之间的关系,采用SF-36量表、家庭功能评定量表和社会支持评定量表对212名煤工尘肺患者进行问卷调查。单因素分析显示,煤工尘肺患者在SF-36量表的躯体疼痛、总体健康、活力、情感职能、精神健康5个维度的得分与对照组的差异有统计学意义（p〈0.05）。生存质量得分与家庭功能得分呈负相关,生存质量得分与社会支持得分呈正相关。以生存质量得分为因变量,以家庭功能和社会支持的分量表得分为自变量进行多元逐步回归分析显示,生存质量的影响因素为社会支持利用度、家庭功能的总的功能、情感介入、社会支持的客观支持和问题解决。研究结果表明,煤工尘肺患者生存质量较低,与其家庭功能和社会支持有密切关系,需要从家庭功能和社会支持采取综合措施,提高煤工尘肺患者的生存质量。     

构建煤炭企业负责人培训考核长效机制研究

针对我国煤矿普遍存在的规模差异较大、生产条件复杂、煤炭企业负责人文化素质和专业素质都相对较差的实际情况,对我国现在实施的培训和发证的相关政策和措施进行了分析和研究;指出现行的培训考核机制对煤炭企业负责人能力和水平的差异缺乏针对性,对煤炭企业可持续发展对管理人才的知识结构需求缺乏系统性,对煤矿企业主要负责人的综合素质的提高缺乏强制性;提出了现行开展的对煤炭企业负责人的培训考核机制应该结合煤矿矿长安全培训、矿长资格培训和煤炭职业经理人培训所提出的综合素质要求,结合地区和企业的煤炭行业的实际和发展需要,实行统筹规划、分段培训、分级考核和发证,以构建符合我国实际的培训考核长效机制;并按照这一设想进行了长期的探索和实践,取得了一些可以借鉴的经验和成果。
