The Ministry of Water and Environment in Bolivia has asked the Dutch Government for support in relation to the drought issues they face. Last week, a team consisting of team leader Otto de Keizer (Deltares) and Johannes Hunink (FutureWater) left for Bolivia. As a result of El Niño, the country is struggling with a long and extreme drought period, which in November 2016 led to an acute water shortage in the capital La Paz and other areas of the country.
The Dutch government together with the Dutch water sector founded the Dutch Risk Reduction Team (DRR-Team). With the DRR instrument the Netherlands is able to cover the entire disaster management cycle from mitigation, preparedness and response to recovery.
To address the drought problem in Bolivia, the DRR-Team has been asked to provide recommendations on drought early warning and drought information systems, both on technical aspects as well as on institutional issues. The team has held talks with the Ministry of Environment and Water, the La Paz and Potosí drinking water companies, and the municipality of La Paz. In addition, they also consulted with SENAMHI: the National Hydrometeorological Institute. The DRR-Team drew up with a team of experts of the World Bank that supports Bolivia with several necessary investments to reduce vulnerability to drought.
Groundwater is one of the most important freshwater resources for mankind and for ecosystems. Assessing groundwater resources and developing sustainable water management plans based on this resource is a major field of activity for science, water authorities and consultancies worldwide. Due to its fundamental role in the Earth’s water and energy cycles, groundwater has been declared as an Essential Climate Variable (ECV) by GCOS, the Global Climate Observing System. The Copernicus Services, however, do not yet deliver data on this fundamental resource, nor is there any other data source worldwide that operationally provides information on changing groundwater resources in a consistent way, observation-based, and with global coverage. This gap will be closed by G3P, the Global Gravity-based Groundwater Product.
The G3P consortium combines key expertise from science and industry across Europe that optimally allows to (1) capitalize from the unique capability of GRACE and GRACE-FO satellite gravimetry as the only remote sensing technology to monitor subsurface mass variations and thus groundwater storage change for large areas, (2) incorporate and advance a wealth of products on storage compartments of the water cycle that are part of the Copernicus portfolio, and (3) disseminate unprecedented information on changing groundwater storage to the global and European user community, including European-scale use cases of political relevance as a demonstrator for industry potential in the water sector. In combination, the G3P development is a novel and cross-cutting extension of the Copernicus portfolio towards essential information on the changing state of water resources at the European and global scale. G3P is timely given the recent launch of GRACE-FO that opens up the chance for gravity-based time series with sufficient length to monitor climate-induced and human-induced processes over more than 20 years, and to boost European space technology on board these satellites.
In this project, FutureWater is in charge of a case which aims to prototype and calibrate a Groundwater Drought Index based on the G3P product, and to integrate it into InfoSequia, the FutureWater’s in-house Drought Early Warning System. The new InfoSequia component will be tested for inherent reliability and flexibility at the basin level in a total area of about 145 000 km2 in Southern Spain which largely relies on groundwater resources. This pilot region comprises three large basins (Segura, Guadalquivir and Guadiana) with many aquifers and groundwater bodies where very severe dynamics of overexploitation and mining have been identified and declared. Unsustainable groundwater development threats the water security in the region, but also the ecological status and preservation of unique and highly protected ecosystems in Europe (e.g., Doñana National Park, Daimiel National Park, Mar Menor coastal lagoon).
To support a sustainable and equitable management of increasingly pressurised water resources, water authorities need to have access to up-to-date information on the availability and use of those resources. However, such information is often scarce, or may at best be only available as static data in reports. This may lead to sub-optimal decisions, particularly during critical situations such as droughts, may diminish water security, slow down economic and social development, and even lead to disputes and conflicts on water allocation.
HERMANA aims to foster the development of an integrated water management decision support system (DSS) that supports daily, tactical and strategic decision-making related to water resources in Colombia, and specifically in the Cauca Valley Basin. The HERMANA tool will be a comprehensive system able to provide valuable, relevant, and reliable groundwater and surface water data, and information to high level decision makers and specific users, to an appropriate level of detail and at the time that it is required. HERMANA, which is based on the example of such integrated real-time decision support systems recently developed at selected Water Boards in the Netherlands, it will be executed by a solid team of experts in water resources, DSS, operational, tactical, and strategic water management and governance, that can work together to support water managers and governments around the world.
The main objective of this project is to develop an integrated water management decision support system, HERMANA, which will enable CVC to make more informed decisions related to water management in the Cauca Valley. This project will contribute primarily to better informed and more transparent decision-making in managing water resources, in particular through the incorporation of the dynamic nature of groundwater resources and use, considering these as an integral part of the water resources in a river basin. This will contribute to a more balanced management of surface and groundwater resources and lead to improved water security. The goal is that this system will foster IWRM, as well as improving water use and efficiency.
Concretely, the goals of this project are to:
Provide CVC with an instrument to communicate with stakeholders;
Advance in the process of involving stakeholders in water-related decision-making;
Progress in the co-design of integrated water resources management tools and evaluate the lessons learned that can also be applied in the Netherlands;
Strengthen the cooperation between the consortium partners for future collaboration;
Develop a product to support IWRM that combines the complementary expertise of the Dutch water sector, including businesses (HydroLogic, FutureWater), a knowledge institute (Deltares), and public authorities (DWA), which can be replicated elsewhere; and
Develop a business case to show the viability of this system so that it can be implemented in other river basins in Colombia and elsewhere around the world.
Role of FutureWater
In this project, FutureWater has the mission to bridge the gap between scientific knowledge and practical applications for drought monitoring and sustainable water management. FutureWater will configurate and implement the InfoSequia drought monitoring system (www.infosequia.es) as part of HERMANA, and will contribute to the definition of scenarios and strategies for water management in the Cauca Valley region, and to the overall evaluation of existing tools and models available in HERMANA.
IMPREX exploits the idea that understanding present-day risks is an effective starting point for adapting to unprecedented future events. Taking into account potential climate trajectories and a collection of experiences in various vulnerable water-related sectors, IMPREX will put current management decisions and practices in the context of an emergent future. In addition, the way in which current operational forecasts of potentially high-impact events at various time scales are utilized can still be improved, not only by enhancing the forecasting skill, but also by customizing the information to the stakeholders’ needs, practice and decision context.
The core elements of IMPREX consist of three interconnected science- and user-oriented actions: (a) an improvement in the forecasting and foresighting tools and climatologies of hydrological extremes, (b) application of these developments in the daily practice of stakeholders across different sectors and regions, and (c) dissemination of the experience gained from the sectoral impact analyses to a wider audience by means of user-friendly assessment summaries of impact and adaptation strategies, periodic risk outlooks, and bulletins for public communication.
IMPREX will deliver:
A measurable improvement in forecast skill of meteorological and hydrological extremes in Europe and their impacts
A demonstration of the value of the information on hydrological impacts to relevant stakeholders through a set of representative case studies.
Novel risk assessment concepts that respond to limitations of current methods and practices
A pan-European assessment of existing and adapted risk management and adaptation strategies
A periodic outlook of expected hydrological and water resources (trans-)sectoral risks in Europe linking outputs to existing systems such as the European Flood Awareness System and the European Drought Observatory.
FutureWater leads the coordination of the “Agriculture and Drought” sectoral Work Package. This WP specifically aims to study and evaluate the use of IMPREX weather forecasts and predictions, climate variability, and drought indicators to assess agricultural drought risk and impacts over four case studies and at the pan-European level. An special emphasis will be placed in:
improving our understanding on the relationships between climate variability, hydrological drought indicators, and agricultural production and losses and, finding these relations in four Mediterranean case basins
developing downscaling methods in order to provide agricultural drought indicators useful at the basin level and according to the specific needs of the case study basins and their currently operational drought management systems.
designing appropriate tools and communication/dissemination channels for generating effective and transparent drought alerts to water managers and stakeholders in the agricultural sector.
quantifying the impact of changing rainfall, evapotranspiration and atmospheric recycling dynamics on water fluxes, flows, stocks, consumption and the provision of services to agriculture for the major basins of Europe using a generic analytical framework (WA+).
