    En este trabajo se describe una experiencia de diseño, desarrollo y cálculo de un índice de evaluación de la sustentabilidad agropecuaria. Este índice, que se denominó ISAP (Índice de Sustentabilidad Agropecuaria), se estimó en siete establecimientos agropecuarios del departamento de Anta de la provincia de Salta, en el noroeste de Argentina. El ISAP se construyó mediante la estimación de indicadores previamente seleccionados de manera conjunta con los productores agropecuarios locales durante tres series de encuestas estructuradas y semiestructuradas realizadas entre los años 2012 y 2014.

    Most sedimentary plains occupied by semiarid woody ecosystems have low groundwater recharge rates and high vadose zone salt accumulation. Their cultivation has often led to drainage of water below root zone, displacement of solutes, and rising water tables, affecting, in most extreme cases, long-term viability of agriculture. To explore this possibility in semiarid plains of South America, we characterized vadose flow using chloride data in dry forests of central Argentina, in an area that has been subject to intense deforestation and agricultural expansion during the last century.
