    Besides India, there are a few other countries like Mexico, Spain, Pakistan, Bangladesh and China which also make intensive use of groundwater. This highlight reviews groundwater institutions and policies in these countries, with a special focus on the interlinkages between energy and groundwater. It finds that while there are useful lessons from international experience, none of the other countries offer unmetered electricity to farmers as India does. It is this lack of energy accounting and resistance to metering that is at the heart of the invidious energy-irrigation nexus in India.

    En los sistemas extensivos para la producción de caprinos en el Norte de México, existe una fuerte problemática debido a que la alimentación del ganado está sumamente restringida en los agostaderos dada a la baja disponibilidad de forraje de especies nativas como consecuencia del sobrepastoreo, aunado a las escasas lluvias que en los últimos años se han presentado en el país. El objetivo del presente estudio fue evaluar la calidad de la alimentación de ganado caprino en un Sistema Agrosilvopastoril para satisfacer los requerimientos nutricionales de los caprinos durante todo el año.

    The authors examine the impact of migration on educational attainment in rural Mexico. Using historical migration rates by state to instrument for current migration, they find evidence of a significant negative effect of migration on schooling attendance and attainment of 12 to 18 year-old boys and 16 to 18 year-old girls. IV-Censored Ordered Probit results show that living in a migrant household lowers the chances of boys completing junior high school and of boys and girls completing high school.

    El pasto ovillo es una de las gramíneas mas usadas en la producción animal, en la zona templada de México.

El objetivo de este estudio fue determinar la frecuencia e intensidad de pastoreo que proporcione mayor rendimiento de forraje en una pradera de pasto ovillo (Dactylis glomerata L.).

    Agriculture must expand production for a growing population while simultaneously reducing its environmental impacts. These goals need not be in tension with one another. Here we outline a vision for improving both the productivity and environmental performance of agriculture in the US Corn Belt. Mean annual precipitation has increased throughout the region over the past 50 years, consistent with climate models that attribute it to a warming troposphere.
