The Earth Summit took place in Rio de Janeiro in 1992, marking a new direction in the teaching, diffusion and promotion of environmental awareness, mainly through the ‘Agenda 21’ document.  It proposed the reorientation of education towards sustainable development, increased public awareness, and the promotion of training.

A group of Argentines who took part in the meeting understood the need for these principles to be applied in their country.  They therefore decided to form an organisation which held caring for the environment as the main objective of its work.  On 18 June 1993 they founded the Asociación de Grupos de Recuperación Ecológica y Supervivencia Terrestre (Association of Groups for Ecological Recovery and Survival of the Earth), later called Fundación Agreste.
