A contextual framework for understanding good practice in integrated catchment management

Principles of good practice for collaborative resource management were derived from the literature and their use studied in a range of integrated catchment management processes. Desk-based reviews and interviews with participants allowed the principles to be refined and described within a framework that illustrates the interrelationships between core principles, enabling principles, precursors to a project and the influence of external factors on such collaborative processes. The findings illustrate the importance of these relationships in understanding how success is defined and under what conditions successful outcomes can be achieved. Understanding how these procedural aspects influence outcomes contributes to the wider literature on collaborative resource management that often treats processes separately from their context.     

Relation between management's behavioural intentions toward the environment and environmental actions

Drawing on Ajzen's Theory of Planned Behaviour, this paper analyses whether there is a relation between management's behavioural intentions toward an environmental problem and the company's specific actions in this area, and also considers the impact of the company size on these actions. For the data, a questionnaire was sent to 184 managers employed in industrial companies located in Spain which belonged to the automobile industry. The empirical analysis produces positive and significant regression coefficients and provides support for the hypotheses proposed. Specifically, the results show that the environmental actions carried out in the company respond at least in part to management's behavioural intentions toward these issues and the size of the firm.     

Stewardship among lifestyle oriented rural landowners

Changes in landownership associated with amenity migration are affecting the demographic, cadastral and ecological conditions of rural landscapes. These changes and concerns about their impacts on natural resource management, including ecological conservation, relate to both the structural consequences of landownership change, land subdivision and to the motivations, management ability and attitudes of lifestyle oriented rural landowners. Based on an Australian case study near Sydney, NSW, this paper examines the motivations and practices of such landowners, assesses potential consequences for vegetation and characterises the landowners according to three stewardship types.     

补充型过度捕捞的确认及其对渔业管理的启示

生物学参考点用来指导渔业管理决策,通常以捕捞死亡系数来表达。补充型过度捕捞常常被理解为一个种群被捕捞至补充量出现实质性减少或失败时才发生。该定义很含糊,不能建立生物学参考点,它与捕捞死亡系数挂钩。因此,提出从减少一个世代亲体量的捕捞压力水平出发,定义补充型过度捕捞即是捕捞死亡系数使产卵群体低于其亲代平均生物量的临界点。常规的模型和亲体补充量数据都可确定这一参考点,并与亲体量的更替联系起来,从而实现渔业资源的可持续发展。以印度洋黄鳍金枪鱼渔业为例,计算了其补充型过度捕捞的生物学参考点,提出限制围网诱鱼装置作业,减少幼鱼资源的过度开发,防止补充型过度捕捞发生引起资源的衰退。

Mapping Biological Resources in the Coastal Zone: An Evaluation of Methods in a Pioneering Study from Norway

For many years, the planning and management of terrestrial areas has been supported by a detailed knowledge of the distribution of habitats and their associated species. However, the detailed mapping of biological resources in extent coastal areas, such as the Norwegian coastal zone, is unrealistic due to its enormous coastline. Here, we present a useful and feasible approach and a set of simple, cost-effective methods which are suitable for providing a broad-scale overview of marine habitats and fish resources. This approach was developed in conjunction with a pioneer study conducted along the southern coast of the Skagerrak, where we combined knowledge gathered from local fishermen with scientific knowledge of important species and nature types to establish a coastal sea mapping program. GIS modeling tools were used in both the mapping program and to integrate local and scientific knowledge into digital maps made available to local area management. This multi-faceted approach, which combines local knowledge and scientific methods, provides valuable information with respect to marine biodiversity, and has been used extensively by local environmental management.

高氯酸钾项目生产过程中的环境风险及防范措施

根据国家环保总局发布的"高污染、高环境风险"产品名录(2009年),无机盐产品高氯酸钾属于高环境风险的产品,其生产存在较大风险。高氯酸钾项目在生产过程中的环境风险主要来源于强酸、强碱、有毒有害、易燃易爆等原辅材料、产品,运输、贮存和使用过程产生的燃爆、泄漏、贮运风险以及工艺废气治理措施失效等环节。识别项目产生的环境风险主要包括爆炸风险、泄漏风险、危险化学品贮运风险及氯气直排风险,并从生产管理、生产工艺及贮运等方面提出相应的防范措施。
