Integrated water resources management (IWRM) relies on co-ordination, co-operation and sharing of collected data amongst relevant organizations. This article presents the results of systematic research into non-technical barriers that influence IWRM-related data sharing in transboundary contexts, with a focus on the Mekong River Commission’s procedures for data sharing in Thailand. The current extent of data sharing is quite limited. The main bottlenecks hindering relevant Thai organizations’ sharing data across national boundaries appear to be a perception of limited gains, and concerns for national security. The article concludes that data sharing for IWRM implementation cannot be radically improved without significant changes in the mindsets of the relevant organizations, and suggests how to achieve this.  相似文献

In this paper, we examine the benefits and costs of hydropower development in the Mekong River Basin. We compare four major reports—the Mekong River Commission's (MRC's) Basin Development Plan Programme, Phase 2 (BDP2), the Strategic Environmental Assessment of Hydropower on the Mekong Mainstream (SEA), the Study on the Impacts of Mainstream Hydropower on the Mekong River (MDS), and the MRC's recent council study (CS)—in order to provide the basis for a comparative analysis of the major impact evaluation literature on mainstream dam construction in the Mekong River Basin for the period of 2010–2018. The primary objective of the review is to identify points of agreement, disagreement, inconsistency, and knowledge gaps. Both Mekong River Commission reports (BDP2 and CS) suggest extensive economic benefits for proposed hydropower development, whereas the SEA and MDS indicate that the net impact would be negative. The projected impacts of hydropower development on fisheries, sediment flows, and ecosystems vary widely both in economic and biophysical terms. However, all four reports point to decreased food security and loss of local livelihoods for millions of people as major concerns related to dam development. While considerable resources have been devoted to producing these important studies, the lack of standardization across reports, especially assumptions and methodologies for economic impacts, frustrates efforts at meaningful comparison of their findings and precludes the prospect of clear analytical outcomes or policy impacts. This article is categorized under:
  • Engineering Water > Planning Water
  • Human Water > Value of Water
  • Engineering Water > Methods

Abstract

During the last decade, leaders of the Mekong Countries have found it mutually advantageous to open up the Mekong Sub‐Region (MR) for development and trade, which promises some degree of political stability and regional security. Within the present political, cultural, and economic dynamics, the Mekong River Basin (MRB) ‐ one of the major international river basins in MR ‐ is a powerful catalyst for regional cooperation that facilitates sustainable development and regional stability; if, that is, the effective management intervention is in place to make sure that the benefits and costs of river basin development are spread equitably and peacefully. Nonetheless, there are numerous stumbling blocks in achieving integrated and balanced MRB management, such as limited success in real basin wide planning, implementation and monitoring and a poor knowledge base for supporting informed decision making and, finally, political impediments.

A workable and truly regional cooperative mechanism for integrated management of the MRB is yet to be developed, regardless of the existence of numerous regional institutions and organizations. The present paper proposes new schemes with (re)designing principles and performance determinants for a regional cooperative mechanism.  相似文献

Hydropower development may result in water conflicts among the riparian nations, which, however, can be resolved by benefit sharing. An optimization framework is proposed for a transboundary sub-basin following a cooperative game theoretical approach. A broad range of factors at different levels of cooperation between the riparian countries has been used in the optimization model. As an illustration, the framework is implemented in the Sesan and Sre Pok sub-basins of the Lower Mekong Basin. Higher levels of cooperation lead to greater total net benefits as well as greater benefits to individual countries.  相似文献

Abstract

It is generally accepted that conflicting demands over international rivers will intensify. There is an active debate on whether this will lead to “water wars” or to unprecedented cooperation. Framing the debate in this manner, however, tends to cast the concept of cooperation as all-or-nothing, implying that “cooperation” is an extreme, in direct opposition to “war.” This conceptual construct obscures the many practical levels of cooperation that states can undertake to their mutual advantage. It is important to recognize that it is entirely rational that states will always have a “national agenda” for a river that they share with other states, and that they will cooperate if it serves that national agenda. In practice, there can be a continuum of levels of cooperation, from simple information sharing, to joint ownership and management of infrastructure investments. Furthermore, it may not necessarily be the case that “more” cooperation reaps “more” benefits in all river basins. There are many different types of benefits that can be secured through the cooperative management of international waters, with each individual basin offering different potential cooperative benefits with different associated costs. For each international basin, the optimal mode of cooperation will depend on a mix of factors including hydrologic characteristics, the economics of cooperative investments, numbers and the relationships of riparians, and the costs of parties coming together.  相似文献

采用实测水文资料分析了湄公河流域的洪水特性。结果表明:湄公河流域的洪水主要由暴雨形成,干流水文站年最大洪水主要发生在7~10月;由于河流走向、流域形状与季风活动路线基本平行,全流域性洪水出现的几率很小;老挝境内左岸支流和公河、桑河、斯雷博河汇集而成的\"3S\"河由于地处降雨高值区,多年平均汛期来水量占柬埔寨上丁站的一半以上;我国境内洪水与万象洪水过程同步性几率较大,与上丁站短历时洪水过程同步几率较大,但仍是上丁站长历时洪水过程的重要组成部分。  相似文献

湄公河流域是我国实施\"一带一路\"战略、发展周边外交的重要区域。因此,了解该流域的自然灾害的特征,对于各国增信释疑及我国构建稳固的周边外交关系具有十分重要的意义。本文以比利时EM-DAT数据库为依据,通过统计分析湄公河流域5国1900-2017年的自然灾害数据,初步揭示了自然灾害的时间分布特征和空间分布特征。通过研究可以得到如下结论:洪水、风暴是对湄公河流域国家危害最大的自然灾害,其中,洪水是最主要的致灾因子;从对流域人口生命影响角度看,对湄公河流域国家人口死亡影响最大的自然灾害前3位分别是风暴、洪水和流行病;各国自然灾害的构成大体相同,但不同国家有所区别。2011年GDP15%。  相似文献

This article analyzes key factors affecting transboundary water cooperation in the Brahmaputra River basin at multiple scales. The analysis of multi-track diplomacy reaffirms the potential of actor-inclusive approaches, arguing for a need to go beyond purely focusing on formal legal norms and consider the possibilities of cultural norms of informal processes of cooperation. Various ‘windows of opportunity’ exist in the current phase of the Brahmaputra basin’s development, leading to exploration of a Zone of Possible Effective Cooperation, arising from the effort to scale up multi-track initiatives as well as broader geo-political-economic changes happening across and beyond the basin.  相似文献

随着工业化与城市化不断深化,流域开发对水资源需求总量与质量要求不断提高,但是工业废水、生活污水、禽畜养殖废水等排放量迅速增加,大量未经处理的污废水直接排入周围水体,造成水体利用功能下降,危及水资源安全。在潭江流域水资源调查中发现,目前潭江流域面临着流域发展对资源需求增加与水质下降双重问题,流域饮用水源地优先保护与水资源持续利用已成为潭江流域开发研究的重要内容。通过对潭江流域水资源利用现状、特点与存在问题的分析,提出了水资源持续利用与饮用水源地保护的对策与措施。  相似文献

从历史上看,生态环境意识的变迁决定着水资源管理在生态环境保护中的地位和作用。50年来,由于人口猛增,加上改造自然的能力有了质的飞跃,人类不断地侵夺生态环境用水,从而造成了海河流域生态环境的恶化。为了恢复生态环境,必须建立健全水权管理体制,加强生态环境用水的权属管理,实施水资源分类分级优化配置。  相似文献

为给区域因地制宜布局和发展新质生产力、制定有针对性的新质生产力协调发展政策提供依据,基于新型劳动者、新型劳动资料、新型劳动对象3个维度构建反映新质生产力发展水平的综合评价指标体系,并从流域视角出发,采用2015—2022年21个省(市、自治区)相关数据,运用熵权法、Dagum基尼系数及其分解法、Kernel核密度估计法实证考察长江、黄河、珠江三大流域新质生产力发展水平、区域差异及其动态演进趋势。结果表明:1)在时空分布上,三大流域新质生产力发展水平整体呈上升趋势,长江流域新质生产力及其构成要素的发展处于较高水平,珠江流域处于居中水平,黄河流域处于最低水平;2)在区域差异上,长江流域新质生产力内部差异最小,珠江流域内部差异最大,黄河流域与长江流域间差异最大,流域间差异是三大流域新质生产力总体差异的主要来源;3)在动态演进上,三大流域新质生产力发展水平的流域内差异均呈现减小趋势,尤其是长江流域新质生产力均衡化发展趋势更为明显,珠江流域新质生产力发展的非均衡问题较为突出,黄河流域非均衡发展问题虽然呈现减弱趋势,但总体发展水平相对较低,发展新质生产力任务更为艰巨。  相似文献
