Regenerative means able to or tending to regenerate—to regrow or be renewed or restored, especially after being damaged or lost.
In the natural sciences
Regeneration, in biology, refers to the process by which some organisms replace or restore lost or amputated body parts. Regeneration, as one aspect of the general process of growth, is a primary attribute of all living systems. Without it there could be no life, for the very maintenance of an organism depends upon the incessant turnover by which all tissues and organs constantly renew themselves.
In social sciences
Regeneration recognises that human and planetary health are deeply interwoven, and actively seeks to enable the flourishing of human and non-human life, on an ongoing basis, forever.
