Better global water information through the Global Hydrological Status and Outlook System (HydroSOS) & Reporting

World Meteorological Organization (WMO) (
Intergovernmental organization
)
#SDGAction51142
    Description
    Description

    We cannot manage something well that we don’t measure. The capacity to monitor and manage water resources is fragmented and inadequate. WMO and partners endeavor to improve global water information through a Hydrological Status and Outlook System (HydroSOS) and an annual State of Global Water Resources Report.

    The initiative will (1) enhance the capacities of countries to produce hydrological status assessments and outlooks at seasonal to sub-seasonal scale; (2) integrate such products for policy and decision-making at the national, regional, and global level; and (3) release a yearly global report presenting an overall status of the water resources. Member States, Decision-makers and Stakeholders will be able to respond to questions, such as: “How much water is available in my basin or region at the moment?”; "Is the current situation normal or significantly above/below normal conditions?"; and "How might the local and regional flood/drought situation change in the coming weeks to months?”.

    The initiative focuses on implementing HydroSOS at various scales (regional, national and global) by assessing existing capacities, further developing those capacities and technical applications, and establishing WMO HydroSOS Centers embedded within the WMO Integrated Processing and Prediction System (WIPPS). HydroSOS aspires to build a sustainable and robust global framework for hydrological status and outlook information which is centered on locally produced analysis, supplemented by products from global hydrological models and data centers. HydroSOS portals will ensure the products are open and accessible for WMO Members and other stakeholders.

    The first global report was launched in 2022 which gave an overall picture of the water resources, changes in hydrological storages (groundwater, snow and ice) and major hydrological extreme events and associated losses. The report provided hydrological information to enhance, guide and support water-related decision-making by planners, managers, and policymakers at all levels of government. Once HydroSOS is operational, the Annual State of Water Resources report will present information derived from HydroSOS and serve as a summary of information to guide policy development, climate change mitigation, and adaptation action.

    The governance is overseen by the two technical commissions of WMO and is coordinated by the Hydrological Coordination Panel. The work streams are divided into Technical Development, Implementation, and Coordination, constituted by teams of experts from partners and WMO staff. HydroSOS implementation is also supported by the other WMO activities like the HydroHub (focusing on innovation to increase capacities of Member states), and WHOS (WMO Hydrological Observing System which works as a broker for effective data/information transfer)

    The HydroSOS and the State of Global Water Resources report are elements included in the WMO Plan of Action for Water based on a decadal Vision and Strategy for Hydrology with eight Ambitions that support the operational hydrological community. Specifically, “By 2030 a cooperative global community is successfully addressing the growing challenges related to hydrological extremes, water availability and quality, and food security, by advancing operational hydrology through enhanced science, infrastructure, capacity-building and related services, in the context of sustainable development and enhanced resilience.”

    Expected Impact

    WMO’s objective is to help us, and future generations to understand better how water availability and the frequency of floods and droughts respond to the changing climate and anthropogenic activities and the resulting impact on the water-energy-food-ecosystem nexus (SDG 6, 2, 7, 11, 13, and 15).
    HydroSOS is currently being implemented at global, regional, and national/local scales. Over three years, it is expected that HydroSOS will be functional and share the hydrological status of at least 50 countries and the hydrological outlooks of at least 20 countries. Complementing HydroSOS, the annual State of Water Resources report is fed by the information from countries participating in HydroSOS, helping to reduce the gaps in information at the global scale by taking action at the national/regional scales.

    Several socioeconomic sectors, if not all, depend on water. Making hydrological information available is the first step to empower stakeholders to make informed decisions. HydroSOS will inform planning, decision and policy-making, addressing current gaps in the availability of water information. Understanding water resource availability allows better planning and support for safe drinking water and sanitation (SDG 6) and informs impacts on people (SDG 1, 2, 3, 4 and 5), industries (SDG 9), and the environment (SDG 14 and 15). Providing baselines and projections on changes to water resources, also informs mitigation and adaptation to climate change and its impacts on society (SDG 13), as well as potential security issues (SDG 16). HydroSOS empowers national and international water management and catalyzes international cooperation through trusted water data, assessments, and outlooks.

    Improved global water information through HydroSOS will accelerate the implementation of the SDGs by fostering international and regional cooperation among countries and ministries (SDG 17). Shared information products will support decision-makers and river basin-wide collaboration. National Meteorological and Hydrological Services (NMHS) will support ministries of environment, water, climate change, transport, etc., by providing timely information on the state of their water resources. This will further provide an integrated regional/global overview of the resource to assist the aid & development sector, NGOs and UN entities in their anticipatory action and response to water-related hazards (SDG 11.5). The HydroSOS framework is an enabler for establishing Early Warning for all (EW4ALL) by strengthening the monitoring and forecasting capacities for floods and droughts of the Members through various implementation levels.

    Finally, better water data and information is paramount in guiding intergovernmental discussions regarding shared water resources. This initiative underscores the integral role of Member States in achieving this and strongly encourages Members to strengthen their monitoring network for timely data collection of the various components of the water cycle – groundwater, soil moisture, streamflow and snow and ice, etc. – to share the data obtained under the WMO Unified Data Policy encouraging open data and knowledge.

    Partners

    The Global Hydrological Status and Outlook System (HydroSOS) is being implemented through collaboration with different partners, including National Meteorological and Hydrological Services (NMHS) and affiliated water departments, transboundary basin organizations, research organizations, and with consultations with stakeholders from various sectors, including agriculture, energy, disaster risk reduction (DRR), dam operators, etc.
