Uzbekistan is highly sensitive to climate change which will cause changes in the water flows and distribution: water availability, use, reuse and return flows will be altered in many ways due to upstream changes in the high mountain regions, but also changes in water demand and use across the river basin. The resulting changes in intra-annual and seasonal variability will affect water security of Uzbekistan. Besides, climate change will increase extreme events which pose a risk to existing water resources infrastructure. An integrated climate adaptation approach is required to make the water resources system and the water users, including the environment, climate resilient.
This project will support the Ministry of Water Resources (MWR) of Uzbekistan in identifying key priorities for climate adaptation in the Amu Darya river basin and support the identification of investment areas within Amu Darya river basin. The work will be based on a basin-wide climate change risk assessment as well as on the government priorities with an explicit focus on reducing systemic vulnerability to climate change.
The project will undertake:
Climate change risk analysis and mapping on key water-related sectors, impacts on rural livelihoods, and critical water infrastructures.
Climate change adaptation strategic planning and identify barriers in scaling up adaptation measures at multiple scales with stakeholder consultation and capacity building approach.
Identification of priority measures and portfolios for integration into subproject development as well as for future adaptation investment in the Amu Darya river basin. The identification will cover shortlisting of potential investments, screening of economic feasibility, and potential funding opportunities.
FutureWater leads this assignment and develops the climate risk hotspot analysis, and coordinates the contribution of international and national experts, as well as the stakeholder consultation process.
Agriculture is the most water demanding and consuming sector, globally responsible for most of the human induced water withdrawals. This abstraction of water is a critical input for agricultural production and plays an important role in food security as irrigated agriculture represents about 20 percent of the total cultivated land while contributing by 40 percent of the total food produced worldwide.
The FAO Regional Office for Asia and the Pacific (FAO-RAP) is concerned about this increase in water use over the last decades that has led to water scarcity in many countries. This trend will continue as the gap between water demand and supply is projected to widen due to factors such as population growth and economic development, and environmental factors such as land degradation and climate change.
Unfortunately, solutions to overcome the current and future water crisis by looking at the agricultural sector are not simple and have often led to unrealistic expectations. Misconceptions and overly simplistic (and often erroneous) views have been flagged and described over the last recent decades. However, uptake of those new insights by decision makers and the irrigation sector itself has been limited.
The “Follow the Water” project will develop a Guidance Document that summarizes those aspects and, more importantly, quantifies the return flows that occurs in irrigated systems. Those return flows are collected from a wide range of experiments and are collected in a database to be used as reference for new and/or rehabilitation irrigation projects.
The FAO/FutureWater project will also develop a simple-to-use tool to track water in irrigated systems using so-called “virtual tracers”. The tool will respond to the demand for a better understanding the role of reuse of water in irrigated agriculture systems. An extensive training package, based on the Guidance and the Tool, is developed as well.
FAO plays an essential role in backstopping the development of the Guidance and the Tool and promoting. FutureWater takes the lead in development of the Guidance, the Tool and the training package. With this, FAO and FutureWater will contribute to a sustainable future of our water resources.
Pakistan is ranked as the 8th most climate vulnerable country in the world as per the Global Climate Risk Index (2019) and in recent years has been facing the worst brunt of climate change. Irregular and intense precipitation, heatwaves, droughts, and floods have severely impacted the agriculture and water sector. Approximately, 90% of the country’s freshwater resources are utilized by the agricultural sector. However, lack of information services makes it a challenge to implement a water accounting system for improved water resources management.
The GCF funded project titled “Transforming the Indus Basin with Climate Resilient Agriculture and Water Management” aims to shift agriculture and water management to a new paradigm in which processes are effectively adapting to climate change and are able to sustain livelihoods. FAO Pakistan, as per the request of the Ministry of Climate Change, has designed the project to develop the country’s capacity to enhance the resilience of the agricultural and water sector. There are three major components:
1. Enhancing information services for climate change adaptation in the water and agriculture sectors
2. Building on-farm resilience to climate change
3. Creating an enabling environment for continued transformation
FutureWater will be actively involved in Component 1 which focuses on facilitating the development of a water accounting system and improving the availability and use of information services. Given the limited data availability in the region, FutureWater will integrate the use of remote sensing technologies within the existing Water Accounting methodology to address this gap. A capacity and needs assessment will be conducted and a series of tailor-made trainings will be designed subsequently to enable key government stakeholders to use open-source geospatial analysis tools as well as models to estimate real water savings, particularly in the context of agriculture. The trainings will help build the country’s capacity to implement water accounting at different spatiotemporal scales and cope with the worsening impacts of climate change.
The Lunyangwa Dam is the source of water supply for Mzuzu City, Ekwendi Town and surrounding areas. Currently, the yield of the dam is lower than the annual average daily water demand from the dam. A quick intervention for this problem is to raise the spillway of the Lunyangwe Dam.
In order to determine the height of the redesigned spillway, FutureWater conducted a hydrological study for the Lunyangwa Dam Catchment to determine flood extremes for several return periods. HEC-HMS was used for calculating the peak volumes and discharges. The input for the HEC-HMS model was retrieved using satellite-based datasets for rainfall and terrain. Furthermore, the flood routing was simulated with an elevation-storage curve. The output of this study will be used for the redesign of the spillway.
The Mediterranean Region is facing growing challenges to ensure food and water supply as countries experience increasing demand and decreasing availability of natural resources. The nexus approach aims at managing and leveraging synergies across sectors with an efficient and integrated management of the Water, Energy, Food, and Ecosystems Nexus (WEFE).
BONEX objectives are to provide practical and adapted tools, examine concrete and context-adapted technological innovations, enhance policies and governance and facilitate WEFE Nexus practical implementation that balances the social, economic, and ecological trade-offs.
The project aims at producing a novel, transdisciplinary, diagnostic WEFE Bridging Framework, which combines methods in a context-specific manner and going beyond disciplinary silos. The diagnostic tools supporting the framework will be developed and tested in seven selected demonstration projects in the region which pilot innovative technologies (agrivoltaics, wastewater reuse systems, etc.).
As a result, BONEX will provide policymakers and practitioners with an interactive decision-making tool to evaluate trade-offs, synergies, and nexus solutions approaches in a transdisciplinary manner. Further, it will produce valuable experiences with tailoring innovative WEFE Nexus technologies that provides new business opportunities. The WEFE nexus approach is required to implement sustainable agri-food systems and preserve ecosystems.
Within BONEX FutureWater will actively contribute to the package of diagnostic tools. A simple water accounting tool (REWAS) will be used to evaluate if ‘Real Water Savings’ are achieved with innovative technologies. The water accounting tool evaluates water flows at field level and irrigation district scale and determines if any ‘real savings’ are achieved. The tool also incorporates the aspects of food production (crop yield) and will introduce components for evaluating energy and water quality aspects to complement the WEFE Nexus aspects. The seven demonstration projects will be used to demonstrate and iteratively develop this water accounting tool. A hydrological analysis is performed in selected locations to also evaluate the impact at basin (watershed) scale. Eventually the results from these analyses will be translated into policy implications and achievements of SDG’s (sustainable development goals).
This project is part of the PRIMA programme supported by the European Union.
In irrigated agriculture options to save water tend to focus on improved irrigation techniques such as drip and sprinkler irrigation. These irrigation techniques are promoted as legitimate means of increasing water efficiency and “saving water” for other uses (such as domestic use and the environment). However, a growing body of evidence, including a key report by FAO (Perry and Steduto, 2017) shows that in most cases, water “savings” at field scale translate into an increase in water consumption at system and basin scale. Yet despite the growing and irrefutable body of evidence, false “water savings” technologies continue to be promoted, subsidized and implemented as a solution to water scarcity in agriculture.
The goal is to stop false “water savings” technologies to be promoted, subsidized and implemented. To achieve this, it is important to quantify the hydrologic impacts of any new investment or policy in the water sector. Normally, irrigation engineers and planners are trained to look at field scale efficiencies or irrigation system efficiencies at the most. Also, many of the tools used by irrigation engineers are field scale oriented (e.g. FAO AquaCrop model). The serious consequences of these actions are to worsen water scarcity, increase vulnerability to drought, and threaten food security.
There is an urgent need to develop simple and pragmatic tools that can evaluate the impact of field scale crop-water interventions at larger scales (e.g. irrigation systems and basins). Although basin scale hydrological models exist, many of these are either overly complex and unable to be used by practitioners, or not specifically designed for the upscaling from field interventions to basin scale impacts. Moreover, achieving results from the widely-used FAO models such as AquaCrop into a basin-wide impact model is time-consuming, complex and expensive. Therefore, FutureWater developed a simple but robust tool to enhance usability and reach, transparency, transferability in data input and output. The tool is based on proven concepts of water productivity, water accounting and the appropriate water terminology, as promoted by FAO globally (FAO, 2013). Hence, the water use is separated in consumptive use, non-consumptive use, and change in storage.
A complete training package was developed which includes a training manual and an inventory of possible field level interventions. The training manual includes the following aspects:
Introduce and present the real water savings tool
Describe the theory underlying the tool and demonstrating some typical applications
Learn how-to prepare the data required for the tool for your own area of interest
Learn when real water savings occur at system and basin scale with field interventions
The study will focus on selection of key traded crops between the EU and Africa and their key producing regions. The tasks will include overall analysis of current practices and the background in the regions, determination of key sensitive parameters in order to select key crops and food products and map hotspot regions. In addition, project team will assess climate risks for these hotspots on key crops and food products and link these risks with the importing countries. Climate risks will be assessed by identifying the multiple climate sensitivities on the food systems in each region, assessing changes predicted by a CMIP6 (latest) climate model ensemble on key agriculture-related climate indices, and analysing impacts on production-related indices, distinguishing between rainfed and irrigated production systems. It will be focused on country specific case studies in each partner country. The impacts of climate change on trade patterns will be evaluated to assess the carbon- and water footprints and virtual water profiles of key traded commodities of these countries. At the end, the project team will focus on policy relevance and assessment of adaptation strategies and identify interventions that will be needed, at which point in the system, and from which sector (or actor) is of interest.
The outcomes of CREATE will be used to increase awareness of the risks that climate change poses to the agro-food trade and the broader economy at large. They can contribute to efforts by the governments (macro-scale), the communities (meso-scale), as well as relevant agricultural producers (micro scale) in the case study countries, by providing essential information for promoting actions towards mitigating the negative consequences of climate change on agro-food trade.
The “Integrated Strategic Water Resources Planning and Management for Rwanda” consultancy project will assess and evaluate the availability and vulnerability of the country’s water resources up to around 2050 taking climate change into consideration.
Based on this, prioritization of investment options in grey and green infrastructure will take place, in order to formulate water resources investment plans. A revised water resources policy will be prepared that is in line with water security targets and SDG 6.
In more detail, the hydrological modelling assessment will result in update water accounts per sub-catchment up to 2050. Field work for assessing groundwater resources in key areas across the country is also performed. A detailed water allocation assessment will be performed using a water resources system model (WEAP), addressing water needs for the various users up to 2050. Water allocation plans will be developed from this modelling work, incorporating stakeholder inputs.
Then, a scenario analysis is performed to evaluate the potential of additional storage in the landscape: grey (reservoirs) and green (through Nature-based Solutions). This analysis will be complemented by field work and a pre-feasibility analysis will be performed on the prioritized options. A SWOT analysis will then lead to a number of possible flagship projects which of which a concept note is prepared.
Support to the revised national policy for water resources management will also be provided by defining new policy statements and actions informed by the results from the previous tasks and developing a new water resources policy that will guide the country towards achieving the NST1 and Vision 2050 targets.
The Swiss Agency for Development and Cooperation’s (SDCs) Global Programme Climate Change and Environment (GP CCE) India is supporting the operationalization of climate change adaptation actions in the mountain states of Uttarakhand, Sikkim and Himachal Pradesh through the phase two of the “Strengthening State Strategies for Climate Action” (3SCA) project that was launched in 2020. The second phase of 3SCA (2020-23), known as the Strengthening Climate Change Adaptation in Himalayas (SCA-Himalayas), while building on the experience and achievements of Phase 1, aims to showcase mountain ecosystem appropriate scalable approaches for climate resilience in water and disaster risk management sectors; using these efforts to enhance the capacities of the institutions across the Indian Himalayan Region (IHR) to plan, implement and mainstream adaptation actions into their programmes and policy frameworks; and disseminating the experiences and lessons at the regional and global level.
Within this programme, SDC has granted a project to FutureWater, together with Utrecht University, The Energy and Resources Institute (TERI), the University of Geneva and a few individual experts. The activities in this project focus on the development and application of climate responsive models and approaches for integrated water resources management (IWRM) for a selected glacier-fed sub-basin system in Uttarakhand and that at the same will find place in relevant policy frameworks paving way for their replication across IHR and other mountainous regions. This will allow the policy makers from the mountain states in India to manage the available water resources in an efficient and effective manner, benefiting the populations depending on these resources.
The combination of future climate change and socio-economic development poses great challenges for water security in areas depending on mountain water (Immerzeel et al., 2019). Climate change affects Asia’s high mountain water supply by its impact on the cryosphere. Changes in glacier ice storage, snow dynamics, evaporation rates lead to changes in runoff composition, overall water availability, seasonal shifts in hydrographs, and increases in extremely high and low flows (Huss and Hock, 2018; Lutz et al., 2014a). On the other and, downstream water demand in South Asia increases rapidly under population growth and increasing welfare boosting the demand for and electricity generation through hydropower. To address and adapt to these challenges integrated water resource management (IWRM) approaches and decision support systems (DSS) tailored to glacier- and snow-fed subbasins are required.
To fulfil the mandate outlined by SDC a framework is presented for IWRM and DSS for Himalayan subbasins consisting of three integrated platforms. (i) A modelling and decision support platform built around a multi-scale modelling framework for glacier and snow fed subbasins, based on state-of-the art and “easy to use” modelling technology. (ii) A stakeholder engagement platform to consult key stakeholders, identify key IWRM issues and co-design a new IWRM plan for Bhagirathi subbasin. (iii) A capacity building platform with on-site training and e-learning modules for the key project components: glacio-hydrological modelling, IWRM and DSS, to ensure the sustainability of the approach and pave the way for upscaling to other subbasins in the Indian Himalayan Region.
The three platforms are designed designed to be flexible, integrated and interactive. Moreover they align with the three outcomes of the project, thus contributing to: develop and validate an integrated climate resilient water resource management approach (Outcome 1); increase technical and institutional capacity in the fields of hydrological modelling, IWRM and DSS (Outcome 2); support the embedding of the IWRM approach tailored to glacier-fed Indian Himalayan subbasins in policies, and provide generic outputs and guidelines to facilitate upscaling to other subbasins in the Indian Himalayan Region (Outcome 3).
The modelling and decision support platform is designed for operation under the data scarce conditions faced in Himalayan catchments, and yields reliable outputs and projections. The modelling toolset covers the Bhagirathi watershed (Figure below) and consists of 3 hydrological models: (i) a high resolution glacio-hydrological model for the Dokriani glacier catchment (SPHY-Dokriani). Key parameters derived with this model are upscaled to (ii) a distributed glacio-hydrological model that covers the Bhagirathi subbasin (SPHYBhagirathi). Outputs of this model feed into (iii) a water allocation model that overlays the SPHY-Bhagirathi model in the downstream parts of the basin, where water demands are located (WEAP–PODIUMSIM Bhagirathi). This modelling toolset is forced with downscaled climate change projections and socio-economic projections to simulate future changes in water supply and demand in the subbasin. On the basis of stakeholder inputs, adaptation options are identified and implemented in the water allocation model for scenario analysis. Thus, socio-economic projections and adaptation options are co-designed with the stakeholders to ensure maximum applicability, and are tailored to the requirements for formulation of the new IWRM plan. The outputs of the modelling toolset feed into the Decision Support System, where they are presented in such a way that they can truly support decision making in this subbasin. Results of the modelling, decision support and stakeholder engagement platforms jointly support the co-design of an IWRM plan for the subbasin. Capacity in glacio-hydrological modelling, IWRM and the use of DSS is built through a combination of on-site training and e-learning; replicable training modules are developed for glacio-hydrological modelling, IWRM and DSS in general and for this particular approach to support implementation and sustainability.
The objectives of the Norfolk Water Fund is to secure good quality, long-term water resources for all water users, while protecting the environment and showcasing the county as an international exemplar for collaborative water management. The programme seeks to demonstrate how cross-sector, integrated water management and can deliver multiple benefits and help achieve the county’s net zero targets.
Water Funds are a well-established model for facilitating collective action to address water security challenges through the implementation of nature-based solutions (NBS) as a complement for more traditional so-called ‘grey’ infrastructure such as pipelines and treatment plants. Norfolk is one of two European pilots selected for Water Funds by The Nature Conservancy (TNC), to add to their global portfolio of Water Funds.
To deliver this programme, a variety of technical activities are required. These include assessing Water Security Challenges in the county, identifying the most relevant NBS to the context, and prioritising the most effective locations and strategies for their implementation. FutureWater will support these technical activities with NBS and water resources expertise alongside coordinating technical partners.
