The emergence of Disaster Risk Financing

As extreme weather events become more frequent and severe, the impact on lives, livelihoods and economies is undeniable. Across the disaster risk management sector, there is increasing recognition that new financial solutions are needed to support resilience, response and recovery efforts.

The insurance and finance industry has a long history of assessing and managing risk. In recent years, we’ve seen how these skills can be applied to the challenges faced by climate vulnerable countries, helping to improve disaster preparedness and financial resilience. This has led to the emergence of disaster risk financing (DRF) – a structured approach to securing funding for disaster response. This approach reduces reliance on post-event appeals, uncertain aid flows and traditional insurance models that require post-disaster impact assessments before payments can be made.

How DRF works

At its core, DRF is about making sure that funding is available when and where it is needed most. Traditional humanitarian responses often rely on emergency appeals, which can result in delays that worsen the impacts of disasters. In contrast, DRF provides pre-arranged financial mechanisms that allow governments, humanitarian agencies and communities to respond faster and more effectively.

Key elements of DRF include:

  • Robust risk data – The frequency and intensity of events are assessed before they occur through high-quality modelling and analysis, forming the foundation for DRF schemes that are both effective and financially sustainable.
  • Pre-agreed financing – Funds are secured in advance, removing uncertainty and enabling early action.
  • Parametric triggers – Payouts are based on predefined thresholds, such as rainfall intensity or flood extent, ensuring rapid disbursement without the need for post-disaster damage assessments.

For example, a well-designed DRF scheme can release funding to a government or agency as soon as flood levels exceed a certain threshold. This means recovery efforts can begin immediately, rather than waiting for impact assessments and international appeals. The funds can be used to support government-led response efforts, channelled through local agencies, or even provided directly to affected communities. By using recognised risk analytics, these solutions also make it possible to transfer some of the financial burden to insurance and capital markets, reducing overall costs for governments and donors.

Challenges and opportunities in DRF

JBA has worked extensively with donor banks, humanitarian organisations and governments, applying our expertise in flood modelling to the design, pricing, implementation and monitoring of DRF instruments. Through this work, we’ve gained valuable insights into key challenges and opportunities:

  • Understanding flood hazard complexity – Flooding can take many forms. Some events develop gradually over large areas, such as the monsoon-driven flooding in Pakistan in 2022, which affected millions of people over several months. In contrast, flash floods can occur suddenly in steep-sided valleys following short but intense downpours. Capturing this full spectrum of flood risk requires high-resolution modelling and sophisticated analysis. This is why JBA has developed global flood mapping at 30 metres and continues to invest in comprehensive risk modelling.
  • Data availability and quality – Reliable risk analytics depend on accurate data. However, in many regions, river gauge networks are sparse, and satellite data is not always available at the frequency needed for real-time monitoring. Addressing these gaps is crucial for improving DRF solutions. JBA is actively working to strengthen forecasting and monitoring capabilities through hydrometeorological projects, such as our work in Sierra Leone, where we have supported the development of high-impact weather and flood forecasting systems. Additionally, our work in Vietnam has focused on strengthening integrated flood risk management, which contributes to enhanced forecasting and early warning efforts.
  • Integrating multiple tools for a holistic approach – Effective DRF solutions require combining various data sources, modelling approaches and financial mechanisms. JBA applies this approach through Integrated Flood Risk Management (IFRM), which combines structural measures, forecasting systems, institutional coordination and financial instruments to build resilience. By integrating these elements, we help governments and humanitarian organisations develop effective risk management strategies and make informed, timely decisions.
  • Stakeholder engagement and capacity building – Communities living in flood-prone areas have deep local knowledge of their risks. However, DRF mechanisms and financial risk modelling are often unfamiliar concepts. Clear communication, collaboration and capacity-building efforts are essential to ensure local agencies can make informed decisions and maximise the benefits of DRF.

Where next? Opportunities for DRF

With flood risk increasing in many regions, the need for solutions that strengthen resilience, reduce disaster impacts and accelerate recovery has never been greater.

Disaster risk financing is one of many tools available to governments, NGOs and humanitarian organisations. It provides transparent, structured and efficient financial solutions that can be quantified at inception and aligned with government priorities. By combining sophisticated flood risk modelling with financial mechanisms, DRF offers a proactive approach to disaster management and brings together the needs of governments and society with the resources of the private finance sector for mutual benefit.

As we continue to develop and refine DRF solutions, the focus will be on advancing risk analytics, strengthening financial innovation and helping to ensure that funding reaches those who need it most – when they need it most.
