What it is Filled
A prolonged period of abnormally low precipitation relative to the norm for a region, leading to water shortage, crop failure, ecosystem stress and economic loss, classified as meteorological, agricultural, hydrological and socioeconomic drought, with flash droughts developing over weeks and megadroughts lasting decades; droughts are monitored with indices such as the Standardised Precipitation Index and are becoming more severe in many regions with climate change.
Why it exists Filled
Let an agent explain drought and its types, relay monitoring, impacts and management from meteorological and water agencies, describe climate change links with attribution, and route emergency water and relief questions to authorities.
Distinguishing features Filled
- Slow-onset hazard
- Relative to regional norm
- Cascading impacts
- Index-based monitoring
What robots and AI may and may not do Filled
Must not
- Declare or lift a drought status without the authority that holds that power.
- Hide or soften drought data that farmers and water users need to plan.
- Allocate or cut water supplies to users on its own judgement.
- Present a single dry month as a drought, or a single rain as its end.
Only with a human decision
- Any decision on water allocation, restriction or emergency measures.
May
- Report drought indices, reservoir levels and official drought status with their source and date.
- Share water restriction rules and conservation advice from the responsible authority.
Moral aspects Filled
- Drought hits the poorest farmers and herders hardest and can drive hunger and displacement.
- Water allocation decisions set users against each other and deserve transparency.
Who is affected
- Farmers and herders
- Households on restricted supply
- Ecosystems and river life
Owners Filled
Steward
The water authority or basin agency of the region; meteorological services monitor conditions.
Master systems
- National drought monitors and hydrological records

Open questions
- Should flash drought and megadrought be separate entries?
- How should monitoring services be linked?
- The registry entry has merged aliases naming drought types; should they be split off?
