• A key objective for the EO4SD on water resources management is to support the development of the required human, technical and institutional capacity to empower stakeholders with the ability to utilize the Earth Observation (EO) data and services in an independent and sustainable manner.

  • Today is the World Water Day and we would like to thank all our partners who work so tirelessly for the better management of water resources. Please be assured that the EO4SD team will keep supporting you in 2018.

  • Following our visit to Centre Regional AGRHYMET the EO4SD team continued the African user consultations with back-to-back workshops in Djibouti and Lusaka from 20th to 30th of September.

  • From 12th to 14th of September, the EO4SD on water resources was gathering more than 20 stakeholders at Centre Regional AGRHYMET in Niamey (Niger).

  • From 2 to 4 May, 2017 the EO4SD was in Dar es Salaam to present and discuss how Earth Observation can support the Zambezi Watercourse Commissions (ZAMCOM).

Global water resources are being rapidly exploited through unprecedented population growth and widespread unsustainable management practices. The current pace, magnitude and spatial reach of humankinds impact on water resources is now a very real concern for future development and peace. In simple terms this means that water resources are being polluted and over-exploited on scales never witnessed before. Currently, millions of people still live without access to safe drinking water, mainly in sub-Saharan Africa and Asia. Agricultural irrigation remains by far the largest consumer of freshwater resources, accounting for about 70% of freshwater use, with this number expected to increase by a further 20% by 2050.

In response to the widespread recognition of impending water scarcity, in January 2015, the World Economic Forum declared the water crisis as one of the highest global risks. However, despite this growing concern, a water crisis can be viewed as management crisis, that can be mitigated through the application of best-practices and sound water management policy.

Considering the significant risks of letting a potential water crisis unfold unabated, the new Sustainable Development Goals (SDGs), approved in September 2015, set specific targets for water (SDG 6). This ambitious SDG aims to ensure the availability and sustainable management of water and sanitation for all. One of the central pathways outlined to achieve this goal is through integrated water resources management (IWRM) at multiple levels, including transboundary cooperation (cf. SDG Target 6.5). The successful implementation and monitoring of IWRM initiatives requires access to reliable data and information on key water related challenges. There is now a growing awareness that Earth Observation (EO) data has the potential to serve these data needs. This is especially relevant in the context of Official Developing Assistance (ODA), which normally target regions where policies and management decisions are more often based on sparse and unreliable information.

Since 2008 the European Space Agency (ESA) has worked closely with International Financing Institutions (IFIs) and Client States to harness the benefits of EO for global sustainable development. Earth Observation for Sustainable Development (EO4SD) is a new ESA initiative which aims at increasing the uptake of EO-based information in regular development operations at the national and international level.

Objectives

Specifically, for water resource management the EO4SD will seek to demonstrate the benefits and utility of EO services in response to stakeholder requirements for water resources monitoring and management at local to basin scales.

Some of the key water related priority areas where EO-based geo-information is needed include:

  • River basin characterization and change monitoring (e.g. hydrological network mapping, long-term climate change analysis)
  • Water supply and sanitation (e.g. monitoring of water quality, extent and level of lakes and rivers to support management for agricultural, industrial and urban water use)
  • Hydrological management (e.g. modeling and forecasts of runoff, river discharge and groundwater abstraction)
  • Water productivity (e.g. mapping of biomass production, evapotranspiration and crop type)
  • Risk management of natural hydrological hazards (e.g. mapping and forecasting of flooding, drought, landslides)
  • Industrial activity assessment (e.g. monitoring of freshwater fisheries, aquaculture, hydropower and mining)

Portfolio

The EO4SD portfolio represent the EO-based information services which can support key priority issues for water resource management and planning.

  • Surface water monitoring

    Knowing the extent and levels of surface water bodies and wetlands is crucial for designing effective water management strategies.

  • Water quality monitoring

    Clean fresh water is a serious environmental challenge,and Earth Observation has become an increasingly important tool to monitor water quality on a regular basis.

  • Monitoring crop and vegetation water demand

    Information on irrigated areas and the water demands of crops helps to optimize crop production and the use of limited water resources.

  • Hydrological modelling and monitoring

    Knowing the expected flow of river systems helps to understand the seasonal dynamics of water availability. This information can be used for planning infrastructure and irrigation or used as an operation forecasting tool to predict river discharge.

  • Natural risk management

    Earth Observation offers innovative solutions to manage risks and reduce impacts from natural disasters such as drought, flooding and landslides.

  • Groundwater mapping and exploitation

    Sustainable use of groundwater resources ensures that the benefits from this valuable water source are preserved for long-term development goals.

  • Hydrological network mapping

    Changes in river courses and coastlines can cause disruption to navigation systems and can act as an indicator for areas vulnerable to erosion.

  • Industrial activity assessment

    Earth Observation can be used for more sustainable planning of industrial development and can monitor its environmental impact over time.

  • Vegetation and land cover characterization

    Vegetation and land cover are intrinsically coupled with the water cycle. Mapping the extent of specific land cover types and changes over time is made possible only through Earth Observation.

  • Settlement Characterisation

    Growing urban human settlements is one of the most significant global trends with wide reaching impact on freshwater resources.

  • Digital elevation models

    Accurate DEMs are arguably one of the most important sources of spatial information used for managing river basins.

  • Thematic base layers

    Using thematic base layers makes communication of maps and imagery to stakeholders more effective by fostering a common understanding of location and scale.
