In 2019, María del Carmen Ventura Patiño wrote about the rental of farmland in Relaciones, the journal of El Colegio de Michoacán. She described it as “un trato de palabra que se celebra entre las partes” (a deal by word made between the parties). For this reason, she noted, there is hardly a reliable record of it. She cited the agricultural census of 2007, which counted 2,667,000 rented hectares.
