Desert Traffic: The Dynamics of the Drug Trade in Northwestern Mexico

The semiarid expanses of northern Mexico have long been a haven for drug trafficking and shipment into the southwestern United States. During the past 3 decades, a more specialized and dedicated drug industry has used the long U.S.-Mexican border to move illicit narcotics. Northern Mexico is not a heavily indigenous zone, and yet some native populations have been adversely affected by this recent industry, and not just a few have taken a role in it. Two states in northern Mexico that still have indigenous peoples are Sonora and Chihuahua. Both of these semiarid states are more sparsely populated than the rest of Mexico, yet both share a long, expansive border with the United States. Thus, neither state has escaped the activities of the drug industry, and some of the major drug cartels are located in this region (figure 8.1), the largest in urban areas such as Ciudad Juarez in the state of Chihuahua and Culiacán in the state of Sinaloa. Although these urban areas are the economic and logistical centers of two large cartels, an aspect frequently ignored in the literature, and certainly in policy circles, is the variety of scales of production in this industry. Aside from these giant cartels, drug cultivation, production, and transportation are also common at lesser scales, and the difficulties and dangers associated with drug production and trafficking extend to these small farmers. Small plots of marijuana (Cannabis sativa) and poppies (Papaver somniferum) dot the northern Mexican landscape, especially in the foothills and high peaks of the Sierra Madre. Most of the poppy production lies further south, in the states of Michoacan, Guerrero, and Oaxaca. Marijuana (Cannabis) is by far the more common of the two illicit crops grown in Mexico, partly because of its longer history of cultivation in the country’s mountainous regions and partly because of its greater ease of integration into agriculture. Poppy fields are a lot harder to hide, both from neighbors and from more interested authorities. Marijuana is also more easily intercropped with more common agricultural crops. Intercropping is the practice of growing two or more crops in the same field or parcel of land, and it is common when farmers need to maximize total output per unit of area (Wilken 1987: 248). I have seen marijuana integrated with corn, bean, squash, sunflower, and tomato plants.
