Introduction to Impact-based Forecasting (IBF) for Early Action

26 February 2023
10 am to 4 pm
Institute of Disaster Management (IDM), Khulna University of Engineering and Technology (KUET)

The training on Introduction to Impact-based Forecasting (IBF) for Early Action was held in collaboration between Intellectuals Center, Nepal, and Khulna University of Engineering & Technology, Bangladesh to increase the conceptual understanding and knowledge of Master students on Impact Based Forecasting approach to the early warning system.

Overview of Impact-based Forecasting

By predicting the impacts of the hazard as well as the event itself, one can act early, in a more precise and concerted way to minimize the potential impacts of a disaster where it occurs.

Impact–based forecasting (IBF) translates meteorological and hydrological information into location–specific impacts; these more targeted and meaningful warnings can trigger anticipatory actions. IBF moves from the traditional way of forecasting “what the weather will be” to a new type of service focused on “what the weather will do”. IBF combines a weather or climate forecast of a hydrometeorological hazard with information about people and places at risk, to anticipate sector- specific and context-specific impacts. IBF breaks the silos of forecasting that exist between hydro- meteorologists and people who can take early action, allowing for the development of more efficient sectoral responses. By focusing on impacts and communicating these, it is expected that the population at risk and the responding professionals will have a better understanding of potential disruptions, which can be used to develop triggers to identify when and where to take appropriate early actions.

Objectives of the training

  • Introducing the key steps in an Impact Based Forecasting (IBF) approach to early warnings
  • Apply the concepts of an IBF approach to fictional scenarios, understanding and considering which components and processes could be most readily adopted in Bangladesh


  • Master Students (Disaster Management, Civil Engineering, Environment and so on)
  • Faculties

Training’s outputs

By the end of the training, the students were able to

  • Explain the rationale for using an Impact Based Forecasting (IBF) approach to warnings
  • List different steps required for implementing the IBF approach
  • Define common terminology associated with IBF approaches
  • Identify hazards related to meteorology and hydrology
  • Determine vulnerability and exposure to these hazards to assess risk
  • Understand the components of a risk matrix
  • Understand how a risk matrix can be used to inform guidance and/or advice
