Resumen:

This chapter analyses water management in Mexico in the context of global environmental change (GEC) and dual environmental and social vulnerability. The research questions are as follows: How can Mexico overcome the present unequal access of water without further destroying the precarious water and food security, and how could small-scale farmers depending now on rainfed agriculture support the recovery of the food sovereignty in the country? To answer this question this chapter studies the development model of integrated water management to explore the nexus between water and food. Mexico has an unequal supply of water: Only 31 % of water is available for 77 % of the population and produces 87 % of the GDP. Furthermore, 77 % of water is used in agriculture often with low efficiency in the arid northern region by agribusiness for exporting vegetables to the USA. The present situation of food insecurity in Mexico is also related to increasing food imports (virtual water) within the framework of the North American Free Trade Agreement (NAFTA). To a large extent, climate change (CC) induces floods and droughts, which are exacerbated by unsustainable urban development, where the Metropolitan Valley of Mexico City (MVMC) overuses existing aquifers. Therefore, only an environmentally sustainable management of water, recycling and reuse of treated water, will offer this densely populated country food and water security in the future. © Springer International Publishing Switzerland 2015.
