Predicting Droughts – SEED-FD Progress Insight

The SEED-FD project is addressing critical gaps in drought forecasting by developing advanced tools, including flash drought and seasonal drought forecast products, as well as a drought tracking algorithm. These innovations aim at supporting timely responses and effective resource management, particularly in regions vulnerable to water shortages and extreme weather.

Understanding the Challenges of Drought Forecasting

Droughts are complex natural phenomena that evolve over time, and forecasting them involves significant challenges. Flash droughts, for example, develop rapidly within days or weeks, making them difficult to predict and leaving little time for action. Seasonal droughts, on the other hand, require long-term weather forecast data and must account for diverse regional conditions.

Limited data availability, especially in vulnerable regions, and the inherent uncertainty in weather forecast models further complicate accurate predictions. Addressing these gaps is critical to reducing societal and economic vulnerabilities.

Innovative Solutions by SEED-FD

The SEED-FD project is developing three key drought forecasting tools to fill current service gaps:

  1. Flash Drought Forecasts: This tool identifies areas at risk of rapid-onset droughts up to 20 days in advance, enabling proactive measures to protect agriculture and water supplies.
  2. Seasonal Drought Forecasts: By analyzing river discharge anomalies, this product delivers predictions up to six months ahead, supporting long-term planning for water resources.
  3. Drought Tracking Algorithm: The project is integrating reanalysis and seasonal forecasts into a tracking algorithm to analyze the evolution of droughts in time and space. This tool will provide a clearer picture of how droughts evolve, supporting dynamic management strategies.

The Methodology Behind the Developments

SEED-FD’s methodological framework begins by assessing the predictability of drought conditions using the CEMS dataset (Copernicus Emergency Management Service). This involves analyzing historical data to understand patterns and testing potential indicators to predict droughts. Each product follows a tailored approach to address the unique characteristics of drought events.

Once predictability is established, specific indicators are developed to forecast the targeted drought events. These indicators are first tested on a global scale and subsequently refined through focused analyses in SEED-FD’s use case study regions, like the Paraná, Danube and Bhima river basins. These regions cover diverse hydrological challenges and provide valuable insights into the dynamics and vulnerabilities of droughts.

In the coming months, the most suitable indicators for the three drought products will be thoroughly tested. Following this, prototypes will be created to apply these indicators to real forecast data. This crucial step will transition the project from retrospective analyses to practical applications, paving the way for more accurate and actionable drought forecasting tools.

Impacts on Stakeholders and Disaster Resilience

The new forecasting products developed by SEED-FD address critical timeframes in drought management:

  • Short-Term: Flash drought forecasts allow local governments and farmers to respond quickly, protecting crops and conserving water.
  • Long-Term: Seasonal forecasts aid in strategic planning, from reservoir operations to emergency preparedness in water-scarce regions.

For communities in vulnerable areas, these advancements mean improved resilience against drought-induced crises, safeguarding livelihoods and ecosystems.

Predicting Droughts – Conclusion and Outlook

SEED-FD is advancing drought forecasting by combining scientific methods with practical applications. In the coming months, the project will finalize its prototypes, transitioning to real-time applications in its test regions. The new tools are expected to enhance disaster management and resource planning, ensuring a stronger response to the challenges of drought in a changing climate.
