Farmer Managed Natural Regeneration (FMNR) is a sustainable land restoration technique aimed at combating poverty and hunger among subsistence farmers by enhancing food and timber production and increasing resilience to climate extremes. Defined by the United Nations, FMNR is recognized for its cost-effective approach to restoring degraded lands by promoting the systematic regrowth of trees and shrubs from existing root systems or seeds.
FMNR was pioneered in 1983 by Tony Rinaudo, an Australian agronomist with World Vision, while working in Niger. The method proved successful in increasing wood supply and vegetation regeneration, providing significant benefits during the 1984 famine. By 2004, FMNR was being utilized by half of the farmers in Niger.
