oasis
Let an agent explain oases and their formation, describe kinds and notable examples, relay water management, agriculture and conservation from geographic and development sources, and distinguish oases from other desert features.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain oases and their formation, describe kinds and notable examples, relay water management, agriculture and conservation from geographic and development sources, and distinguish oases from other desert features.
A fertile area in a desert or semi-desert where water from springs, wells, rivers or aquifers supports vegetation and often permanent settlement, from small palm groves to large cultivated regions such as the oases of Morocco, Egypt, the Sahara and Central Asia; oases have been nodes of trade routes and agriculture for millennia, depend on careful water management such as qanats and foggaras, and are threatened by groundwater depletion, salinisation and climate change.
What it is for: Water, agriculture and settlement in deserts.
It can be explain formation and kinds; describe notable examples; relay water management and threats; distinguish from related features.
Distinguishing features
Water source in aridity
Date palm agriculture
Trade route nodes
Fragile water balance
What it looks like
A green patch of palms and fields amid arid land, often around a spring or pool.
Physical character
Al-Ahsa oasis area: about 85 km2 - among the largest
Moroccan oases: hundreds count - Draa, Tafilalet and others
How it is recognised
Fertile water-fed area in desert
Spring, well, river and aquifer oases, Moroccan and Saharan oases
A wadi is a dry riverbed; an irrigated desert farm without natural water source is not a traditional oasis

What the second pass must settle
- Should notable oases be separate entries?
- How should water and heritage sources be linked?
- The registry entry has a merged alias naming a national set of oases; should it be split off?
