Upstream-Downstream focuses on climate-related information in decision-making at the community level. The game can be especially useful for  neighbouring upstream and downstream communities – the game shows what results cooperation in managing the consequences of flood, drought and deforestation could bring forth for a public good.


Facilitator sets the game and explain the rules.

Players make decision in groups how to act in face of the climate change.

The magnitude of the flood or drought is set by a roll of dice.

Facilitator ends the game with debriefing and discussion with the players.


Decision-making. Flood. Disaster risk.


Upstream-Downstream can help understand how decisions made in an upstream community can affect a downstream community and vice versa how information about probability of drought or flood can affect decision-making the benefits and tradeoffs related to risk preparedness in the context of climate variability and change.
