Mikael D. Wolfe transforms our understanding of Mexican agrarian reform through an environmental and technological history of water management in the emblematic Laguna region. Drawing on extensive archival research in Mexico and the United States, Wolfe shows how during the long Mexican Revolution (1910-1940) engineers' distribution of the water paradoxically undermined land distribution. In so doing, he highlights the intrinsic tension engineers faced between the urgent need for water conservation and the imperative for development during the contentious modernization of the Laguna's existing flood irrigation method into one regulated by high dams, concrete-lined canals, and motorized groundwater pumps. This tension generally resolved in favor of development, which unintentionally diminished and contaminated the water supply while deepening existing rural social inequalities by dividing people into water haves and have-nots, regardless of their access to land. By uncovering the varied motivations behind the Mexican government's decision to use invasive and damaging technologies despite knowing they were ecologically unsustainable, Wolfe tells a cautionary tale of the long-term consequences of short-sighted development policies.

Agriculture is expected to face increasing water risks that will impact production, markets, trade and food security - risks that can be mitigated with targeted policy actions on water hotspots. This report develops the hotspot approach, provides an application at the global scale, and presents a mitigation policy action plan. The People's Republic of China, India and the United States are identified as countries facing the greatest water risks for agriculture production globally. A global simulation shows that, in the absence of action, water risks in Northeast China, Northwest India and the Southwest United States in particular could have significant production, price and trade consequences. Agriculture water risks could also result in broader socio-economic and food security concerns. Farmers, agro food companies, and governments can all play a role in responding to water risks at hotspot locations. A three-tier policy action plan is proposed to confront water risk hotspots, encompassing targeted responses, adapted national policies, strengthened market integration and international collaboration.
