As one of the most climate-vulnerable countries and heavily dependent on the Indus River system for agriculture, Pakistan faces growing risks from rising temperatures, shifting precipitation, and increasing seasonal variability in snow and glacier melt. Modelling of climate change scenarios indicates that, under a business-as-usual pathway, these pressures will pose serious threats to farmer livelihoods and the wider agricultural sector. Reliable, transparent, and sector-disaggregated information on where water comes from, how it is stored, and how it is consumed is essential for shifting the basin toward a more resilient and sustainable water management pathway.

With support from FAO, the project will develop a water accounting system that maximizes the use of satellite remote sensing, complemented by in-situ data for inputs and validation. The work covers four key outputs:

  1. Critically reviewing existing draft water accounting reports and training materials produced by stakeholders, identifying gaps in methodology and datasets
  2. Developing a holistic WA methodology that accounts for available water resources, changes in storage, outflows, water use, and demand across agricultural, industrial, domestic, and environmental sectors
  3. Building a calibrated and validated water accounting system of models and codes, based on free and open-source software, capable of generating water accounting results for the Indus Basin and two provinces
  4. Producing water accounting reports for the Indus Basin, Punjab, and Sindh, including historical supply-demand gaps, water balances, and spatial distribution maps.

To ensure the system is sustainable and locally owned, FutureWater will deliver comprehensive hands-on training to government officials, enabling them not only to run the models but also to understand the underlying theory and modify the system in the future. By integrating advanced hydrological modelling, energy-based evapotranspiration estimation, and the latest land use classification, the resulting water accounting system will provide the Government of Pakistan with a powerful, replicable tool to support climate-resilient agriculture and water management across the Indus Basin.

I-DIP builds on InfoSequia, an advanced toolbox that integrates satellite data, local observations, and machine learning to monitor and forecast droughts. A new flash drought indicator, tailored to Pakistan’s climate, will be developed and embedded within NDMC’s existing system. The project will enhance early warning capacities, safeguard food and water security, and contribute to national climate adaptation efforts, paving the way for I-DIP’s upscaling across Pakistan.

Beyond monitoring, I-DIP will connect its forecasts to decision-making tools. Impact information will be disseminated through advisory bulletins and the inFarmer app (developed by WaterSprint), already widely used among farming communities. Field facilitators deployed by the Better Cotton Initiative will translate these insights into actionable guidance for farmers, enabling them to adapt irrigation practices, adjust cropping calendars, and mitigate potential losses. This integration of cutting-edge drought science with established communication networks ensures that early warnings are transformed into practical actions at the field level.

By embedding I-DIP within NDMC’s operational system, the project directly strengthens Pakistan’s early warning capacity for droughts, aligns with national climate policies, and supports the country’s commitments under the Sustainable Development Goals. In the longer term, the pilot is expected to catalyse scaling of I-DIP across Pakistan, offering authorities a state-of-the-art tool to anticipate and manage such extreme events.

The approach of FutureWater and Galayr is designed to be both scientifically rigorous and contextually grounded, ensuring that the developed drought model is locally relevant, sustainable, and fully integrated into existing national systems such as those of SODMA and NADFOR. The model will merge top-down (data-driven, machine learning-enabled) and bottom-up (stakeholder-informed) approaches, combining satellite data, climate indices, and indigenous knowledge to co-develop impact-based forecasts and consensus-based triggers for anticipatory action.

For the development of the drought forecasting model and the knowledge transfer we will focus on the following pillars:

  • A phased work plan that spans institutional capacity assessments, model development, validation, stakeholder consultations, and hands-on capacity building.
  • Application of state-of-the-art forecasting models ranging from ARIMA and regression to more advanced machine learning techniques, while maintaining focus on usability and institutional adoption.
  • A strong emphasis on knowledge transfer, including training programs and the establishment of a collaborative knowledge-sharing platform using the FutureWater Academy platform
  • A robust risk management plan, including mitigation strategies for data scarcity, stakeholder disengagement, and institutional turnover.

 

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 double 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 below).
  • 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 FutureWater’s Drought Early Warning System called InfoSequia (figure below).
