Located on the side of the San Juan Volcano, La Yerba is a small town of 800 people whose main income is tied to coffee and avocados. The community comprises 35 Ejidatarios–communal land designed for agricultural production. Each Ejidatario, or joint landowner/farmer, has rights to a plot of land that continues indefinitely down their family line, as long as the land is under constant cultivation. This ideology dates back to Aztecs.
