Climate change is predicted to have major impacts on small-scale farmers in Mexico whose livelihoods depend on rain-fed maize. We examined the capacity of traditional maize seed systems to provide these farmers with appropriate genetic material under predicted agro-ecological conditions associated with climate change. We studied the structure and spatial scope of seed systems of 20 communities in four transects across an altitudinal gradient from 10–2,980 m above sea level in five states of eastern Mexico.

The Climate Action Tracker (CAT) compares and assesses national and global action against a range of different climate targets across all relevant time frames. This report assesses whether Mexico’s current policies and climate action pledges meet the country's targets and approach the targets required for a global 2°C or lower pathway. According to the report, Mexico is among the countries most advanced in reducing emissions from deforestation and ensuring afforestation through payment for environmental services.

El mundo no puede eliminar el hambre sin cerrar la brecha que existe en la agricultura entre hombres y mujeres. Con igual acceso a recursos productivos y servicios como tierra, agua y crédito, las mujeres agricultoras pueden producir entre un 20 y 30 por ciento más de alimentos, suficientes para sacar del hambre a 150 millones de personas.

En muchos países en vías de desarrollo, las mujeres producen la mayor parte de los alimentos para el autoconsumo. Las campesinas, al igual que sus familias, viven principalmente de la agricultura aunque las condiciones para desarrollar esta actividad sean poco favorables.

Unprecedented pressures on land have been created as new areas are cultivated, taken over by expanding urban centres or are abandoned due to degradation, climate change and conflict. These developments have strained the rules, processes and institutions that determine which land resources are used, by whom, for how long and under what conditions.

Se analiza la forma de propiedad que ha regido a los recursos fósiles en México bajo una perspectiva histórica que va desde el Porfiriato hasta la Reforma energética de 2008. Se intenta asociar el régimen de propiedad al papel económico-social asignado a PEMEX y sus modificaciones, el desempeño de la industria y las estrategias neoliberales para hacer transitar la industria de un control estatal a uno en favor de las corporaciones internacionales y el sector privado nacional bajo la administración del presidente Felipe Calderón Hinojosa (2006-2012).

Land use/cover change (LUCC) is one of the main factors that control the terrestrial carbon (C) cycle. We examined the effect of LUCC on topsoil C, microbial biomass C (MBC) and microbes mediated processes related to C circulation and their relationship with other soil properties in low-latitude mountain temperate forests. We selected three sites in the northwest of Cofre de Perote volcano (Mexico) in an altitudinal gradient (piedmont, lower mountain slope and mid slope).

Carrying capacity estimates based on digestible protein (DP) and energy (DE) are useful in comparing effects of land management practices or the ability of different vegetation communities to support herbivores. Plant secondary compounds that negatively affect forage quality would be expected to change nutritionally based estimates of carrying capacity. We evaluated the effect of plant secondary compounds on nutritionally based carrying capacity estimates of white-tailed deer (Odocoileus virginianus Zimmerman) in Tamaulipan thorn scrub of northern Mexico.
