The Asian Development Bank (ADB) is considering supporting the (re)construction of four wastewater treatment plants in Stepnogorsk, Satpaev, Zhezkazgan, and Balkhash. Detailed engineering designs are being prepared by designers recruited by Vodokanals. Climate change impacts may exacerbate environmental pollution and other adverse effects of aging infrastructure on service delivery. FutureWater conducted a Climate Risk Assessment (CRA) to ensure that climate impacts are fully considered in the detailed design and construction phases.

The CRA identified the main vulnerability components for the four proposed wastewater treatment plants as: (i) extreme precipitation leading to stormwater runoff, (ii) low flows causing water quality problems, (iii) flooding of infrastructure (both fluvial and pluvial), (iv) power supply outages, and (v) heat stress. FutureWater’s risk assessment, which considered the combined effects of hazard, vulnerability, and exposure, concluded that all five major identified risks require attention. Since the draft designs already account for the current extreme climate conditions, and due to relatively modest projected climate changes (temperature, precipitation, wind), the need for additional adaptation measures will be relatively modest.

FutureWater’s assessment contributed to ensuring that the four wastewater treatment plants will be climate-resilient, thereby securing the investment.

Golovnaya hydropower plant is located 80 kilometers south of Dushanbe and has an installed generation capacity of 240 MW, making it the fourth largest hydropower plant in Tajikistan, after Nurek (3,000 MW), Sangtuda 1 (670 MW), and Baipaza (600 MW). Construction began in 1956, with the first unit commissioned in 1962. Since then, except for one unit, the plant has not undergone significant modernization or improvements to maintain its original performance in terms of efficiency, reliability, safety, or to reduce operation and maintenance costs. Consequently, most of the main electro-mechanical and hydro-mechanical equipment is now in poor condition.

The current project, for which FutureWater conducted a climate risk assessment (CRA), aims to include the rehabilitation of generation Unit 4 of the hydropower plant, which was not part of the ongoing efforts. Unit 4 is expected to add approximately 49 MW to the overall plant capacity. The CRA report evaluated the climate risk and adaptation prospects of the additional project and provides recommendations to enhance its adaptability and climate resilience, further securing this investment.

FutureWater supported this project by conducting a comprehensive review of climate and climate change research, studies, reports, and data related to the Golovnaya hydropower plant. Key findings include: (i) the project should be analyzed within the context of the entire Vakhsh River basin and system; (ii) the operations of upstream reservoirs and hydropower facilities will have a greater impact on Golovnaya than climate change itself; (iii) climate change will affect upstream facilities and thereby indirectly impact Golovnaya. The overall conclusion was that for the specific project (rehabilitating hydropower turbines), the climate risk is relatively low.

FutureWater’s impact was contributing to ensuring that the Golovnaya rehabilitation project will be climate-resilient, thereby securing the investment.

The Lower Chao Phraya region of Thailand is facing increasingly frequent and severe flooding events, which pose significant threats to the livelihoods, safety, and economic stability of local communities. These floods have caused extensive property damage, crop loss, and displacement, thereby hindering overall development in the region. Contributing to these climate-induced flood vulnerabilities are the aging irrigation canal systems, which are inadequate for managing more intense floods, thus exacerbating water-related risks and long-term economic losses. This inefficiency constrains agricultural productivity, perpetuates poverty, and impedes sustainable development.

In response to these challenges, the Asian Development Bank (ADB) is advancing the Enhancing Climate Resilience and Adaptation of the Lower Eastern Chao Phraya Water System Project. The project aims to modernize the aging irrigation infrastructure—comprising canals, regulation gates, and pumping stations—by repurposing them into climate-resilient flood mitigation systems. This initiative seeks to improve water resource management, enhance climate adaptation, mitigate environmental degradation, and mobilize resources for sustainable development.

FutureWater has supported this project by conducting a comprehensive review of significant climate and climate change research, studies, reports, data, and information related to floods and droughts in Thailand from both governmental and non-governmental entities. This included analyzing the availability, quality, and accessibility of climate-related data collected across various regions in Thailand, and identifying data gaps. Additionally, FutureWater evaluated the methodologies, tools, and technologies used for climate data collection, analysis, and modeling to assess their reliability and effectiveness.

FutureWater’s contributions included: (i) identifying strengths and weaknesses in Thailand’s national and international climate commitments, (ii) highlighting the importance of distinguishing between pluvial and fluvial flooding, and (iii) assessing current and projected return periods for temperature, rainfall, and sea level rise. Recommendations were provided regarding the direction in which a comprehensive Climate Risk Assessment should be developed during the design phase of the project.

Uzbekistan is one of the fastest-growing economies in Central Asia, driving a steady rise in energy demand. However, the country faces significant power shortages due to increasing consumption, declining efficiency of aging power plants, and mounting climate pressures, particularly in regions like Tashkent, Samarkand, and Sirdarya. In response, Uzbekistan is prioritizing renewable energy development, especially solar power, to reduce its reliance on fossil fuels. With its abundant sunlight, the country is well-positioned to harness solar energy, and several large-scale photovoltaic (PV) projects are currently in progress.

With the support of the Asian Development Bank, Uzbekistan aims to strengthen energy security and promote environmental sustainability by developing three solar PV plants (100 MW, 400 MW, and 500 MW), two substations, two battery energy storage system (BESS) facilities, and associated transmission lines across Samarkand, Bukhara, Jizzakh, Sirdarya, and Tashkent provinces. To identify the exposures and vulnerabilities of these project components to potential climate risks, FutureWater will utilize advanced downscaled Coupled Model Intercomparison Project Phase 6 (CMIP6) ensembles, along with relevant hazard data and local information, to conduct a rapid Climate Risk Assessment (CRA). The insights gained will enable the Asian Development Bank (ADB) to implement effective adaptation measures and ensure climate-resilient development.

The Rogun HPP is a project that will have a large reservoir capable of providing seasonal regulation. It will supply firm energy during the winter months when demand for electricity is the highest in Tajikistan and will allow for exports of clean electricity to the Central Asia (CA) region and beyond. The Project could play the role of a balancing plant for Tajikistan and the broader Central Asia region to help integrate significant new solar PV and wind generation capacity into the network.

The Rogun HPP was initially designed in the 1970s as part of the development of the Vakhsh River cascade for integrated economic development in the Central Asian republics of the Soviet Union. Construction of Rogun HPP began in 1982 and was then interrupted by political changes resulting from the independence of Tajikistan and the other Central Asia countries. The World Bank in 2011 provided funding to the Government of Tajikistan to conduct a Technical and Economic Assessment Study and an Environmental and Social Impact Assessment. The Government of Tajikistan proceeded with construction without development partners’ involvement. In 2023 a technical assistance grant was approved by World Bank to improve the financial and commercial frameworks of the Rogun HPP Project and to enhance its technical, environmental and social sustainability.

ADB is committed under Strategy 2030 operating priority 3 to support its Developing Member Countries to ensure a comprehensive approach to build climate and disaster resilience. The climate risk management approach of the ADB aims to reduce risks resulting from climate change to investment projects by identifying climate change risks to project performance in the early stages of project development and incorporating adaptation measures in the design.

FutureWater will undertake a climate risk and vulnerability assessment for the Rogun HPP project. Technical studies assessing Rogun HPP’s exposure to natural hazards, hydrology, sedimentation, and
the impact of climate change projections have been completed. These findings are incorporated into the detailed technical design of the project. FutureWater will review all existing studies and any
related studies from reputable sources and consolidate the findings into a climate risk and vulnerability assessment (CRVA) for the project. FutureWater will ensure the methodological approach and technical rigor of the existing evidence base is sufficient, flagging potential insufficiencies which may have a material impact on the conclusions of the assessments. Related tasks to support due diligence will also include a Paris Alignment Assessment in accordance with ADB guidelines, a climate financing accounting estimate, a lifecycle greenhouse gas emission estimate, and Climate Change Assessment summarizing the CRVA findings.

Currently, Pakistan’s energy mix consists of 58.8% thermal, 25.8% hydel, 8.6% nuclear, and 6.8% alternative sources, reflecting efforts to diversify from fossil fuels. Pakistan’s installed electricity generation capacity reached 41,557 MW by 2022, with significant growth in transmission line length over the past 5 years. However, the T&D system has not kept pace with the nearly 15,000 MW capacity added during 2017-2021 (ADB, 2024). Despite investments, transmission and distribution losses averaged about 18% over the last 5 years, exceeding the National Electric Power Regulatory Authority’s (NEPRA) 15.3% target. In 2020, 23.7% of generated energy was lost during transmission, distribution, and delivery (ADB, 2024). Notably, transmission and distribution losses exceed 25%, far higher than in comparable countries (GoP, 2017). Therefore, there is an urgent need to upgrade the existing distribution infrastructure to fulfill the energy demands and ensure steady socioeconomic development in the country. ADB will provide financing for four underperforming DISCOs, selected in consultation with the Ministry of Energy: Sukkur Electric Power Company (SEPCO), Hyderabad Electric Supply Company (HESCO), the Multan Electric Power Company (MEPCO), and the Lahore Electric Supply Company (LESCO) to:

  1. to upgrade the critical infrastructure of these DISCOs to reduce technical losses.
  2. to implement revenue protection measures to improve collections. Additionally, the project design includes embedded climate resilience and reform measures to enhance institutional capacity and financial sustainability.

These rehabilitation efforts will also take into account and address the growing impacts of climate change in four DISCOs. FutureWater will make use of state-of-the-art downscaled Coupled Model Intercomparison Project Phase 6 (CMIP6) ensembles, and other relevant hazards and local information to develop this CRA. Insights from the CRA will be used to devise adaptation strategies. Additionally, FutureWater will be reviewing the existing meteorological monitoring network and recommending additional potential monitoring sites for improved surveillance in the country. To further assist the Government of Pakistan, in actualizing its second Nationally Determined Contribution (NDC) agenda which seeks to reduce greenhouse gas (GHG) emissions per unit of GDP by 50% (compared to the level in 2016), by the year 2030, FutureWater will also develop a GHG account and prepare a Paris Agreement alignment assessment.

Most recent research has focused on identifying historical megadroughts based on paleo-records and understanding their climatic causes, or on the study of “modern” events and their impacts, generally in lowland and plain regions. However, high-mountain regions and snow-dependent catchments have been little studied, and little is known about the impact of megadroughts on the state and dynamics of the cryosphere in mountain water towers.  

In general, catchments dependent on high mountain systems have an intrinsic capacity to buffer the lack of precipitation and excess evapotranspiration that depends on the water reserves stored in the cryosphere (snow, glaciers and permafrost). It is presumed that the this buffer capacity is limited until a tipping point is reached from which the impacts of water shortages and temperature extremes may be amplified and jeopardize the functioning of ecosystems and water resource systems. 

MegaWat has a two-fold objective: 1) to address the knowledge gaps around the hydro-climatic causes of extreme droughts and their impact on the water balance of Europe’s mountain water towers, with special emphasis on the concurrence of compound events and cascading and multi-scale effects, and 2) to develop and propose new adaptation strategies to cope with the duration, extent and severity of future megadroughts and their potential impacts on environmental and socio-economic assets.  

For its implementation, MegaWat focuses on Europe’s high mountain regions and their dependent-catchments. MegaWat aims to develop three products:  

  • Product 1. A methodological framework for the identification and characterization of historical megadroughts during the instrumental period, and the assessment of the role of the cryosphere in supporting the landscape development of downstream areas, or in buffering climate change impacts. Product 1 relies on a combination of climate regionalization, surface energy balance modelling, hydrological simulation, and water evaluation and allocation analysis at the catchment level (Figure 1).  
  • Product 2. A high-resolution, open-access regionalized climate database.  
  • Product 3. A list of potential adaptation strategies useful for the prevention and mitigation of drought impacts, and the enhancement of the water security and resilience of high mountain regions and dependent catchments. These scenarios will be agreed with regional and local actors and stakeholders, and their effectiveness will be evaluated under extreme drought scenarios in three pilot regions in Europe. These pilot regions will be previously selected following criteria of representativeness, strategic importance and vulnerability to droughts.  

FutureWater plays an important role in MegaWat by coordinating the Work Package which aims to develop and test simulation tools that help to adapt to megadroughts and support the decision making process. Two specific objectives are pursued in this Work Package: a) the development of a methodological prototype for quantifying impacts and identifying tipping points for water security in snow-dependent downstream catchments, and b) the generation and the integration of snow drought indicators in the FW’s Drought Early Warning System called InfoSequia (Figure 2).

This project has received funding from the Water4All programme with co-funding from CDTI (Spanish Office for Science and Technology) and the EU’s Horizon Europe Framework Programme for Research and Innovation”. 

The project prepares robust climate mitigation and adaptation pipelines aligned with the Paris Agreement and responsive to DMCs climate change priorities. The TA will support interventions on departmental, sectoral and country levels with key activities including development of a regional strategy, upstream climate assessments, climate pipeline development, government dialogues and capacity building. As part of this project, FutureWater conducts a regional climate risk assessment for ten countries. This includes an assessment of baseline and future climate hazards, exposure and vulnerability and addressing sectoral impacts and adaptation options for a wide range of sectors. In addition country profiles summarizing climate risks for the ten countries are generated. The reginal climate risk assessment feeds into the climate strategy.

Urban flood management in Laos is typically based on a limited, hard infrastructure approach. With the aim to shift this paradigm towards an integrated approach that enhances climate resilience, the project “Building resilience of urban populations with ecosystem-based solutions in Lao PDR” was approved by the Green Climate Fund Board in November 2019 with a GCF grant of US$10 million. United Nations Environment Programme (UNEP) serves as the Accredited Entity for the project. Activities are executed by the State of Lao PDR through the Ministry of Finance and Ministry of Natural Resources and Environment (MONRE) as well as UNEP. The project is implemented across five years (2020-2025) covering four provincial capitals in the country: Vientiane, Paksan, Savannakhet, and Pakse.

One component of the project involves technical and institutional capacity building to plan, design, implement and maintain integrated urban Ecosystems-based Adaptation (EbA) interventions for the reduction of climate change induced flooding. As a part of Integrated Climate-resilient Flood Management Strategy (ICFMS) development, the project conducts hydrological, hydraulic and climate risk assessments to inform climate change adaptation solutions for risk reduction in Vientiane, Paksan, Savannakhet and Pakse.

A consortium of FutureWater, Mekong Modelling Associates (MMA) and Lao Consulting Group (LCG) was contracted by MONRE to implement the related activities. FutureWater leads and coordinates this assignment and contributes remote sensing analyses with state-of-the-art innovative tools, climate risk assessments, and training activities. To ensure sustainability and effective technology transfer, the modelling and mapping infrastructure and trained staff will be hosted within MONRE and a knowledge hub that is established within the National University of Laos.

 

Analysis of the historical climate data and future model projections indicates significant shifts in rainfall patterns. These shifts could influence water availability within the upstream river basins, which are vital for irrigation practices and ecological balance. Furthermore, the study explores variations in temperature -including average, minimum, and maximum values- and evaluates their potential consequences on water demand due to increased evaporation rates and altered crop water needs.

Additionally, this scoping research touches upon the effects of these climatic factors on olive crop phenology and productivity. The study also considers the likelihood of extreme weather events, such as heatwaves and droughts, and their potential to disrupt traditional farming cycles and water resource management strategies.

The outcomes of this analysis are aimed at providing an olive producing firm with insights and strategies to mitigate the adverse effects of climate change on olive production in these targeted regions of Andalucia. By foreseeing potential challenges and preparing for them, a decision can be made on whether to invest or not in order to maintain a leading olive producer on the global stage.
