Disasters are an inevitable part of Banished. Fires can destroy buildings, disease can decimate your population, and starvation can wipe out your town. To mitigate fires, build a Well near clusters of buildings. For disease, a Herbalist and later a Hospital are crucial. Ensure a diverse food supply to prevent malnutrition-related illnesses.
The most common disaster is starvation, often caused by poor planning or harsh winters. Always have a significant food surplus (at least a year's worth) stored in your barns. If a disaster strikes, pause the game, assess the damage, and reallocate workers to address the most pressing issues. Prioritize rebuilding essential structures and ensuring food and firewood supplies are restored quickly.
