Analysis of Social Networks of Water-Use-Related Information in the Rio Mayo Irrigation District (038) in Northern Mexico: Ethnicity, Land Tenure and Land Use

Abstract

(1) Background: In Mexico, 76% of water consumed is used for crop irrigation, and close to half of this is used in 86 irrigation districts for agroindustry throughout the nation. The present study combines a political ecology approach with social networks analysis to identify how water-use-related information networks are structured according to the ethnicity (indigenous and non-indigenous) of the users of the Rio Mayo Irrigation District 038 (RMID) and how these networks are influenced by users’ type of land tenure and land use. (2) Methods: The study involved three stages: identification of social actors that influence water management (SAIWM); application of 118 structured interviews with users of RMID; and ethnographic fieldwork. (3) Results: Thirty SAIWM were identified. Only 11.8% of RMID users interviewed were indigenous farmers and only 5% were indigenous holders of collective landholdings. The information network metrics indicate that indigenous users have less access to information than non-indigenous users. (4) Conclusions: Ethnicity as well as land tenure and land use influence the structure of information networks and determine whether RMID users work as land-holding farmers or as hired labor.
