Growing crops in the mountainous rural areas of Guatemala presents unique challenges, and farmers there rely on a mix of Indigenous practice and new experimental treatments of bio-inputs, infused with micro-organisms. Nathan Einbinder writes about the farmers he met in Guatemala who are innovating collaboratively within their communities to instil resilience and sustainability on their farms.Nathan Einbinder is a lecturer and researcher specializing in agroecology and food systems. Since 2009, he has worked with Indigenous farmers and organizations in the Maya-Achí territory of Guatemala, on issues related to community development, traditional knowledge and soil health, and more recently, homemade biological inputs. This research was conducted while the author was working at the University of Plymouth.Also published in Spanish.https://www.doi.org/10.56661/cf0704b0
