A drought is a type of disaster in Civilization VI: Gathering Storm. It affects Plains and Grassland terrain and it is the longest lasting disaster in the game. At the same time its sheer destructive power is far smaller than other disasters.
- Will damage all food-related improvements in its AOE (Farms, Pastures, Plantations, Camps). Extreme Droughts have 30% chance to also remove these altogether!
- Damaged Improvements cannot be Repaired while the Drought lasts; new food-related Improvements cannot be constructed in the affected area.
- Reduces the Food potential of affected tiles by -1 for the duration of the Drought.
- The presence of vegetation (Woods, Rainforest, Marsh) can prevent Drought occurrence altogether; otherwise tiles which such features which happen to be in the Drought area will be unaffected by Food loss.
- Having an Aqueduct or a Dam in the nearby city will protect all city tiles from Food loss.
There are two different levels of Droughts: Major and Extreme (aka 'Withering'). The first one lasts for 5 turns, the second one - for 10 turns.
Note that after the Antarctic Late Summer Update Droughts gain an additional destructive effect past Climate Change level 5, called desertification. This effect consists of removing tile yields gained earlier in the game from other disasters! The chance of this occurring is 15% for level 5 Climate change, plus additional 15% per each successive level. This makes them potentially even more destructive at this latest stage of the game.
