淡水对生命至关重要。平均而言,如果没有水,一个人最多存活三天。水对牲畜、农业、以及对生产几乎所有的产品和服务都是必不可少的。水是最重要和最广泛使用的可再生能源;水电占全世界总发电量的16%。

淡水资源正在人口和气候压力下不断减少并恶化。负责淡水资源可持续发展的决策者们需要获得准确可靠的水数据。 WMO支持以综合、多学科方法管理水资源。

WMO促进由国家水文部门开展的水资源评价,国家水文部门又反过来提供国内蓄水需求规划、农业活动、水力发电和城市发展所需的预报。

WMO世界水文循环观测系统(WHYCOS)旨在协助国家水文部门建立和维护获取和分发准确及时与水相关信息的系统,而这种信息对于形成水资源综合管理战略至关重要。有了更好的水文信息、评估和预测,会员都能够独立评估其水资源并对洪水和干旱威胁做出响应。

水文和水资源计划(HWRP)旨在促进水资源评估,并支持国家水文部门、流域管理机构和负责水资源管理的其他机构开展一系列活动。其目标是提高水文在可持续发展中的有效利用,以降低洪水或干旱等水相关灾害的风险和影响,并在各个层面上支持有效的环境管理。“质量管理框架 - 水文”为国家水文部门提供了战略、咨询、指导和工具,以在其运行中实现高质量、高效率和高效益。

Floods

In many parts of the world, flooding is a major problem. In the period from 1970 to 2012, storms and floods caused over one million deaths. Flood plains are often attractive areas for human development and a vast share of the world’s population depends, whether directly or indirectly, on a number of key natural resources that are generally provided by floodplains. 

Drought

Drought is a prolonged dry period in the natural climate cylce that can occur anywhere in the world. It is a slow on-set phenomenon caused by a lack of rainfall. Compounding factors, such as poverty and inappropriate land use, increase vulnerability to drought. When drought causes water and food shortages, there can be many impacts on the health of the population, which may increase morbidity and result in death.
