浙江省内河水网对水运物流的影响

首先分析浙江省域范围内主要内河水网的河道总长度长、等级内内河航道里程总量大、内河河道主要分布在经济较为发到的地区等优势,接着讨论汛期水量大枯水期水量小、潮汐影响大、等级航道比例不高、内河通航里程逐年减少等不足。然后结合浙江省水运物流的现实情况,归纳水运物流目前的货物量持续增长、水运量占总货运量的比例变化不大、水运货物多为大宗低值商品等发展特点。最后提出航道信息系统建设及航道资料公布、财税政策适当向航运企业倾斜、错位发展、加大航道投资、增加通航里程,提高通航级别、协调水库蓄水,形成阶梯布局航道等建议。

公共品单向外溢下地方政府间演化博弈——以跨区域水资源生态补偿为例

水资源作为典型的公共品具有很强的外溢性,而且其外溢性具有单向流动的特征,围绕水资源生态补偿引发的流域上下游地方政府间矛盾日益突显.基于演化博弈理论,分析我国跨区域上下游地方政府的博弈过程以及影响因素.研究表明,流域上下游地方政府达成合作的局面长期内主要受上游地方政府惩罚值、下游地方政府惩罚值、下游地方政府对上游地方政府的补偿收益以及上游地方政府保护水资源的成本等四个方面因素影响,而与下游地方政府因水资源受到保护而获得生态收益无关.高层级政府解决水资源补偿问题时,不能仅考虑下游地方政府获得生态收益,而应该综合考虑上游地方政府惩罚值、下游地方政府惩罚值、下游地方政府对上游地方政府的补偿收益以及上游地方政府保护水资源的成本等多方面因素.     

Assessing adaptive capacity of water management organizations. The case study of the municipality of Tomave (Bolivia)

Climate change is only one of several pressure and drivers, such as natural disasters, improvements in technologies and changing customers’ behaviors that water organizations have to relate and adapt to. This places new challenges (e.g. dealing with increased exposure, vulnerability, and uncertainty) to water management and require water organizations to change their perspective on how to deal with water issues. This paper builds on a literature review to identify dimensions and criteria of adaptive capacity and presents a conceptual framework to assess organizational adaptive capacity. The developed framework has been tested within the Municipality of Tomave (Bolivia). The paper results emphasize the incapacity to transform routines as the context is changing leads to the construction of barriers and to the inability of an organization to support the process of change of the society. In addition, the study emphasis that the development of a working system based on cooperation requires first that an organization acquires skills and adapt its routines to the new working system. Furthermore, the development of a participatory process of planning and implementation of policies would help to reduce the trade-offs and conflicts related to water management. Linked to this, the development of a system for monitoring and evaluation of policies implemented organization can contribute to build an iterative mechanism so to allow a redefinition and improvement of such policies.     

Financializing Desalination: Rethinking the Returns of Big Infrastructure

Against the trend prevalent during the 1990s and 2000s, large‐scale infrastructural projects have made a comeback in the water sector. Although sometimes framed as part of a broader sustainable transition, the return of big infrastructure is a much more complicated story in which finance has played a crucial role. In the following article, we explore this encounter between finance and water infrastructure using the case of Britain's first experiment in desalination technologies, the Thames Water Desalination Plant (TWDP). On the surface, the plant appears to be a classic example of the successes of normative industrial ecology, in which sustainability challenges have been met with forward‐thinking green innovations. However, the TWDP is utterly dependent on a byzantine financial model, which has shaped Thames Water's investment strategy over the last decade. This article returns to the fundamental question of whether London ever needed a desalination plant in the first place. Deploying an urban political ecology approach, we demonstrate how the plant is simultaneously an iconic illustration of ecological modernization and a fragile example of an infrastructure‐heavy solution to the demands of financialization. Understanding the development of the TWDP requires a focus on the scalar interactions between flows of finance, waste, energy and water that are woven through the hydrosocial cycle of London.
