How to run a tabletop exercise for disaster preparedness

A tabletop exercise is the simplest way to test a disaster plan before you need it. Teams gather around a table, work through a realistic emergency scenario and identify gaps before a real disaster exposes them. This guide shows conservation teams how to run one, from choosing a credible scenario to capturing the gaps that would otherwise surface in the middle of a wildfire or flood.

Disaster management runs in a cycle from mitigation through preparedness and response to recovery. A tabletop exercise is a preparedness activity, something teams do before a crisis to test how they’ll handle one. A facilitator guides a discussion-based walkthrough of an emergency scenario, allowing the people who would respond to talk through who acts, what information they need and where the plan breaks down. No equipment or personnel are deployed to the field. The only cost is an hour or two and an honest conversation.

During an actual emergency, conservation organizations usually aren't running the response. They're coordinating with whichever agency is in command. While you can write a strong response plan on paper, a tabletop is how you learn whether it survives contact with a live decision. For conservation teams protecting landscapes exposed to fire, flood and storm, it is one of the most useful preparedness activities they can undertake.

Start with a scenario grounded in your hazards

A good exercise begins with a plausible scenario, not a generic one. Choose the hazard most likely to test your landscape, then make it specific. Free data helps you pick something credible: NASA FIRMS shows where active fires appear in your region, flood forecasts show how rivers, streams and drainage systems may behave and a map of your assets in OpenStreetMap shows what sits in harm's way.

Write the scenario as a short brief: what is happening, where and the moment the exercise begins. "A fire is detected fifteen kilometers upwind on a dry, windy afternoon" gives the group something concrete to react to. "A wildfire happens" does not.

Run the session, step by step

The structure is simple and repeatable.

Assign roles. One person facilitates and keeps time. One person takes notes on every gap. Everyone else plays themselves, making the decisions they would make on the day.
Set the scene. Read the scenario brief and the starting conditions, then ask the group what they do first.
Add injects. As the discussion moves, the facilitator introduces new developments, called injects. For example, the wind shifts, the access road floods, a key partner is unreachable, a reporter calls. Each one pressure-tests a different part of the plan.
Ask the same questions at every turn. Who makes this decision? What information do they need? Who do they have to reach, and how? What is missing?
Keep it moving. An hour to ninety minutes is plenty. The goal is to surface gaps, not to script a perfect response.

Walk through a conservation example

Picture a reserve that holds the last local population of a ground-nesting bird. In this scenario, a fire is detected fifteen kilometers away with the wind pushing toward the reserve, late in a dry season.

The group starts confidently, then the gaps appear. No one is certain who has authority to make decisions on the reserve, or who talks to the lead agency once it takes command. The fastest access road crosses a wash that floods after the storms that often precede fire weather. The team's nesting map is a year old, so they cannot say where the birds are this season. The wind turns, and a second agency wants to stage equipment on the reserve. Does the team decide who can operate on the reserve, or does the agency now leading the response?

Finding those gaps around a table costs nothing. However, each one is expensive, or even dangerous, to discover during a fire. That is the whole point of the exercise.

Close with a hotwash, then fix what you found

End every exercise with a frank review, sometimes called a hotwash. While it is fresh, go around the group and name what worked and what did not. The note-taker's list of gaps becomes an action list: assign one owner and a due date to each item, and put the next exercise on the calendar.

This is where a tabletop earns its keep. The exercise is not the deliverable. The closed gaps are, and they feed straight back into the mitigation and preparedness work that lowers your risk before the next season.

A structured way to build these skills

If you want to develop these skills in one place, Conservation Futures Academy offers a short course on disaster mapping and environmental data for conservation. Over about five self-paced hours, you build a preparedness framework, work with open mapping tools and design a tabletop exercise you can run with your team, with no GIS background required.

The course is part of the Academy's practitioner track and is taught by Patricia Solís, executive director of the Knowledge Exchange for Resilience and director of YouthMappers, a rapidly growing consortium of student-led chapters on more than 420 university campuses in 80 countries who create and use open spatial data for humanitarian and development needs.

Conservation Futures Academy is part of ASU's Rob Walton School of Conservation Futures. The course includes a certificate and a digital badge.
