This hydrological assessment delivered river flow estimates for an intake location of a potential hydropower plant in the Lukhra river, Georgia. The assessment included a tuning of a hydrological model based on knowledge of neighboring basins, daily river discharge simulation for an extended period of record (1989-2019), and the derived flow duration curves and statistics to evaluate the flow operation of hydropower turbines. The daily flow calculations for the site can be used in the hydropower calculations, and to assess the overall profitability of the planned investment, considering energy prices, demand, etc.

In the Lukhra basin, snow model parameters were tuned to obtain accurate river flow predictions. Also, the latest technology of remote sensing data on precipitation and temperature (product ERA5-Land) was used to reduce potential errors in flow estimates. Even though these flow estimates are useful for short-medium term evaluations on profitability of the planned investment, climate change pose a challenge for long-term evaluations. Snow-fed systems, such as the Lukhra basin, are driven by a complex combination of temperature and precipitation. Due to future increasing temperature, and changing rainfall patterns, snow cover dynamics change under climate warming. This can lead to shifts in the flows, like a reduction in lowest flows, and higher discharge peaks when the hydrological system shifts towards a more rainfall-runoff influenced system (Lutz et al. 2016). This can jeopardize the sustainability of the project on the long-term. To provide a better understanding of future river flows, it is recommended to develop a climate change impact assessment.

Morocco is a country with extremely arid areas and a complex topography. The majority of climate change related studies predict increases in temperature and generalised decreases in precipitation, however the outputs of these studies are limited in that the resolution of the climate models used is relatively low and therefore often does not pick up variation over areas of complex topography (in which much of the population live). This study therefore helps generate a higher resolution, bias corrected climate dataset. It is also important that trends in precipitation, and more importantly drought, are better understood as Morocco is highly vulnerable to water scarcity. This study therefore focuses on the impacts of climate change on extreme low precipitation, which is directly linked to water shortages and drought events. The study adds valuable new insights to climate change impact analysis in Morocco and is the first to use downscaled climate data to focus on sector wise impact. The data outputs will be located at a number of universities and government ministries in Morocco.

Kyrgyzstan is a highly mountainous country with relatively high precipitation in upslope areas. This, alongside the development and deforestation of basins to make way for industry and agriculture means that land has become increasingly degraded and vulnerable to erosion over recent decades. Reservoirs in the country provide access to water resources and energy in the form of hydropower, but are highly susceptible to sedimentation by eroded material. Sedimentation necessitates increased maintenance costs, reduces storage capacity and disrupts hydropower generation. It is therefore proposed that landscape scale restoration measures (e.g. tree planting) can provide key ecosystem services by reducing vulnerability to erosion and decreasing sediment delivery to reservoirs. This project therefore identifies highly degraded areas of land and determines in which of these interventions are possible. With the outcomes of this study, the World Bank – in partnership with the government of Kyrgyzstan – can prioritise investments in terms of landscape restoration efforts. The outcomes of this project will therefore reduce maintenance costs for reservoirs and contribute to the afforestation and restoration of multiple areas in Kyrgyzstan.

The Sous-Massa basin is located in central Morocco. It represents an arid area that will likely face water resources challenges into the coming decades due to the influence of climate change and socioeconomic development. Indeed, increases in temperatures and decreases in precipitation are anticipated in the Sous-Massa region, alongside more extreme intense precipitation and drought events. It is therefore important the the impacts of climate change on water availability are better constrained to target resilience measures and better prepare for potential future water scarcity.

With the results of this project, IMWI will be able to apply the Water Accounting Plus framework to the Sous-Massa basin, helping to better constrain the likely impacts of climate change on future water availability. This project therefore helps support the targeting and prioritisation of climate resilient interventions which can be taken by the government and other members of the water sector in this area of Morocco.

Hydropower is essential to fulfill future energy demands. Water scarcity is likely to increase due to climate change and aase in water demand. Therefore, Climate Risk Assessments are required before large investments in new and large hydropower stations (>100 MW) are made. Small hydropower (1 – 20 MW) does not require these Climate Risk Assessments yet, but this will eventually happen in the future. Investors are highly interested in the profitability of these small hydropower stations, especially because of the uncertainty caused by future climate change. Current methods for Climate Risk Assessments (CRA) are however still too costly for these small-hydro projects because they are very labor intensive and require specific knowledge.

FutureWater has carried out a feasibility study to assess the possibilities for the development of a “Small-Hydro Climate Risk Assessment tool” (SH-CRA) that can make CRA’s for small-hydro projects cost effective. The starting point of this project to develop the SH-CRA is the recent change in the approach to CRA’s: until a few years ago, these were based purely on climate models, also known as the “Top-down” approach. Nowadays however, investors require a more pragmatic approach in which climate risks are balanced against other risks and presented in a clear way. This new “Bottom-up” approach makes it possible for small-hydro projects to include climate risks in the investment decision.

This feasibility project has therefore investigated whether the “bottom-up” climate risk analysis approach can make it possible to develop such a SH-CRA solution, based on a combination of literature research, an inventory of available technology and potential partners, and competition analysis.

Scientists from around the world have assessed the planet’s 78 mountain glacier–based water systems and, for the first time, ranked them in order of their importance to adjacent lowland communities, as well as their vulnerability to future environmental and socioeconomic changes. These systems, known as mountain water towers, store and transport water via glaciers, snow packs, lakes and streams, thereby supplying invaluable water resources to 1.9 billion people globally—roughly a quarter of the world’s population.

The research, published in the prestigious scientific journal Nature, provides evidence that global water towers are at risk, in many cases critically, due to the threats of climate change, growing populations, mismanagement of water resources, and other geopolitical factors. Further, the authors conclude that it is essential to develop international, mountain-specific conservation and climate change adaptation policies and strategies to safeguard both ecosystems and people downstream.

Globally, the most relied-upon mountain system is the Indus water tower in Asia, according to their research. The Indus water tower—made up of vast areas of the Himalayan mountain range and covering portions of Afghanistan, China, India and Pakistan—is also one of the most vulnerable. High-ranking water tower systems on other continents are the southern Andes, the Rocky Mountains and the European Alps.

To determine the importance of these 78 water towers, researchers analyzed the various factors that determine how reliant downstream communities are upon the supplies of water from these systems. They also assessed each water tower to determine the vulnerability of the water resources, as well as the people and ecosystems that depend on them, based on predictions of future climate and socioeconomic changes.

Of the 78 global water towers identified, the following are the five most relied-upon systems by continent:

  • Asia: Indus, Tarim, Amu Darya, Syr Darya, Ganges-Brahmaputra
  • Europe: Rhône, Po, Rhine, Black Sea North Coast, Caspian Sea Coast
  • North America: Fraser, Columbia and Northwest United States, Pacific and Arctic Coast, Saskatchewan-Nelson, North America-Colorado
  • South America: South Chile, South Argentina, Negro, La Puna region, North Chile

The study, which was authored by 32 scientists from around the world, was led by Prof. Walter Immerzeel (Utrecht University) and Dr. Arthur Lutz (Utrecht University and FutureWater), longtime researchers of water and climate change in high mountain Asia.


In 2017, AFD approved to finance the Water Resources Management and Agro-ecological Transition for Cambodia “WAT4CAM” Program Phase 1. This program will contribute to reduce poverty, develop the economy and reduce the vulnerability of rural populations to climate change by implementing a hydro-agricultural infrastructures rehabilitation program through an integrated approach, targeting the whole chain of water resources management, water services and agricultural production.

The strategy is to achieve intensification of cropping, modernization and climate smart practices to provide farmers with secure access to water. This is a challenging objective and a good understanding of the hydraulics of water flows in dry and wet season is needed. A consortium led by FutureWater was hired to perform WAT4CAM subcomponent 3.1, which concentrates on providing this understanding of both flood and dry season flows, demands and balance in the Preks intended for rehabilitation.

The initial stages of the project include the identification of current data, models and previous work, as well as a field survey with stakeholders. This information will be used to create an accurate and reliable modelling ensemble that makes maximum use of existing capacity in Cambodia. In addition, the consortium will use satellite-derived data products to (i) provide input to the simulation models, and (ii) calibrate and validate model results. Various sources of satellite imagery will be explored to map floods and irrigation practices, to implement an integrated “space hydrology” approach.

The modelling and knowledge generation from this study must support the other WAT4CAM components for the successful implementation of the Prek irrigation system improvements. The modelling itself is thus not the ultimate purpose, but rather the understanding and knowledge imparted to MoWRAM and the other components of the WAT4CAM program.

FutureWater’s role in the project is the overall project coordination and administration, as well as the implementation of satellite remote sensing and climate change analyses in support of the modelling components.

To meet the challenges of regional development and climate change that the Panama Canal river basin faces, the Panama Canal Authority (ACP) has launched the preparation of a land use plan. For this plan, a roadmap will be established (Green Pathway 2050) that should secure water for the population, sustains socio-economic development, enables reliable operations of the Panama Canal, and preserves the ecosystem services of the basin.

The technical cooperation offered through this project will allow the ACP and the IADB to design an intervention implementation program at the strategic and project level to promote the sustainable development of the river basin.

The project is executed in 4 phases (see Figure 1):

  1. Diagnosis: sectoral and comprehensive characterization of the current river basin and regional planning
  2. Prospects: a robust decision making methodology will be applied to quantify the vulnerability of the current and possible future states of the system, considering climate change, socio-economic development scenarios and climate adaptation.
  3. Strategy development: the so-called “Green Pathway 2050” will be developed together with stakeholders, including priority actions, mitigation and adaptation strategies.
  4. Land Use Plan: the plan will address the implementation aspects related to regional zoning, pre-feasibility studies, and a monitoring and evaluation program
Figure 1. Phases of the Project “Formulation of the Land Use Plan for the Panama Canal river basin”.

FutureWater is responsible for assessing, in collaboration with stakeholders, realistic land use scenarios considering the uncertainties imposed by climate change and non-climate factors. A Robust Decision Making (RDM) approach will be applied for this purpose. The work will include the development of a supply-demand model using the WEAP tool and a technical training of ACP staff. Climate change vulnerabilities will be assessed through a bottom-up approach, including stakeholders´inputs from the start of the analysis. The climate change-uncertainties of the land use scenarios will be visualized to stakeholders and a realistic sub-set of scenarios, including adaptation options, will be produced.

The Paris Agreement requests each country to outline and communicate their post-2020 climate actions, known as their NDCs. These embody efforts by each country to reduce national emissions and adapt to the impacts of climate change. As ratifying parties, Armenia, Georgia and Uzbekistan must therefore outline how they intend to implement their NDCs and provide information on what the focus of this spending will be. To support this effort, the Asian Development Bank (ADB) is implementing a knowledge and support technical assistance cluster which will help enhance capacities of developing member countries (DMCs) in meeting their climate objectives by assisting in refining and translating nationally determined contributions (NDCs) into climate investment plans.

In this work package, ADB aims to support Georgia, Armenia, and Uzbekistan with the implementation of their NDCs through developing urban climate assessments (UCAs) and mainstreaming low carbon and climate resilience measures into urban planning processes. FutureWater contributed to this effort by supporting knowledge creation in relation to climate change and adaptation which will help each country to make more informed climate investment decisions.This was accomplished by conducting analysis of downscaled climate model ensembles for different climate change scenarios and synthesising data related to urban climate risk.

Climate change trend assessments were conducted using the NASA-NEX downscaled climate model ensemble combined with ERA-5 climate reanalysis products. To determine climate risk at the urban level, a number of openly available datasets were analysed and compiled using a spatial aggregation approach for 16 cities in the area. Results were presented as user-friendly climate risk profiles at the national and urban scales, allowing for insights into climate trends and risks over the coming century. These will be presented to non-expert decision makers to help support Armenia, Georgia and Uzbekistan develop targeted and informed NDCs.

The overall aim of the Guidance is to supporting adaptation decision making for climate-resilient investments with the main objective to scale-up ADB’s investments in climate change adaptation in Asia and the Pacific. The Good Practice Guidance on climate-resilient infrastructure design and associated training modules will help project teams to incorporate climate projections information into project design. The guideline is based both on insights gained by experts in supporting climate-resilient project development, and on state-of-the-art reviews of emerging engineering design and decision-making protocols that reflect the impacts of climate change. Sector guidance will be provided for agriculture and food security, energy, transport, urban development, and water. FutureWater takes the lead in the water sector guidance.

Training modules targeting member countries officials and ADB operational staff involved in the design of resilient infrastructure projects will be developed to facilitate the wider dissemination of, and capacity building around, the good practice guidance and enhanced availability of climate projections data. Training modules will be developed for both in person delivery at training sessions and distance learning to enable on-demand technical capacity building. The format of the in-person training sessions will be determined in consultation with the operational teams and could take a “training of trainers” approach.
