TURRENT-FERNANDEZ, Antonio et al. Climate change and some agricultural strategies to strengthen food security in Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.7, pp.1727-1739. ISSN 2007-0934.

This essay explores the possible security with food sovereignty of Mexico in the first half of the century XXI, given the impending climate change. The initial conditions include a national population growth, increasing food dependence, and a model of exploitation of natural resources extractive historically, which has led to its significant degradation. It is assumed, that agricultural technology available to the field will be obsolete within the first half of the century due to climate change, with the availability of water for crops and their genetic tolerance to drought and extreme temperatures core variables food production. The fragility of half the arable land in hillside climate change, due to its exposure to soil erosion due to lack of protection is highlighted. The urgent to resource management are discussed to correct deferred investment accumulation of protective adaptations. The research plans intermediate-term (5-10 years) and long term (20 to 40 years) is analyzed. The first to develop transition technologies and the second to develop appropriate advanced stages of climate change technology. The need is observed 1) multiobjective technologies as a MIAF for agricultural management slopes observed; 2) recirculation of elite germplasm of annual crops within and between regions; 3) real-time search and use of native germplasm with genetic adaptation to drought and extreme temperatures; and 4) the development of perennity in the cultivation of corn.
