36 years ago, Martha "Pati" Ruiz Corzo sought a simpler way of life and moved with her husband and two sons from Querétaro city where she taught music in the JFKennedy School, to a rural community in the Sierra Gorda mountains. Co-founded Grupo Ecológico Sierra Gorda IAP in 1987 with local citizens to raise awareness about the biodiversity, the threats and the grassroots movement to build a regenerative future the region. In 1997, she was appointed federal director of the Sierra Gorda Biosphere Reserve by President Zedillo, serving until 2008 when she returned to the civil society organization located in Jalpan de Serra, Querétaro. The result has been the creation of a grassroots environmental movement that has transformed natural resource management practices of the local population and re-oriented public investment from government authorities through environmental education, solid waste management, regenerative practices in soils and forests, sustainable rural tourism, community microenterprise networks, and voluntary carbon offsets for the private sector and subnational climate action.
