Renewable means the resource replenishes at least as fast as the rate of use under stated conditions.
Compare extraction with recruitment, recharge or regrowth and include time scale and access.
A groundwater pump withdrawing 12 units while recharge is 8 creates a deficit despite rainfall.
When is a harvest renewable? when removal does not exceed recovery over the relevant period.
Renewable is conditional, not a permanent label.
