ABSTRACT. Most of Uruguay land is under agricultural use, which remarks the necessity to think about lands with productive systems within a general strategy for biodiversity conservation and ecosystem services preservation. Extensive livestock production is able to reach this objectives but needs to improve productivity for not to compromise economic viability. We present a model for evaluate sustainability in a co-innovation work with 16 pilot farms distributed all around the country.

The present study'ss objective is to characterize behaviour of three different Holstein steers production systems and it implication for husbandry strategies.

The aim of the present study is to characterize general and social pig behavior under two different production systems and to draw inferences about possible implications for the design of husbandry strategies.

En Uruguay los pastizales naturales son el sustento de la ganadería y por lo tanto el principal recurso natural renovable del país. El mantenimiento de la biodiversidad en estos sistemas es valioso para garantizar la provisión de diversos servicios ecosistémicos. Las arañas como grupo mega-diverso son excelentes modelos de estudio para la evaluación de impactos ambientales de este tipo. El primer objetivo de este estudio fue describir la comunidad de arañas de los pastizales naturales en sistemas ganaderos de Uruguay.

Esta cartilla ha sido elaborada por los técnicos que participaron de la experiencia de Validación de Tecnología de Producción de Cerdos para Industria (Proyecto FPTA 220), que se llevó a cabo entre los años 2009 y 2010 en tres predios de productores familiares de la zona de Castillos (dpto. de Rocha).

Abstract: One of the main driving forces of the Apis mellifera colony losses reported worldwide is the nutritional stress associated with monoculture areas. We previously demonstrated under field conditions that nutritional stress that occurred during the fall impacts honey bee colony strength and health in the short and long-term. Pollen supplementation to colonies during a nutritionally stressful period increased adult and brood populations and decreased the infection level of Nosema ceranae.

ABSTRACT. As the biodiversity crisis worsens, its impact on economic and social development is becoming increasingly apparent. Strategies to tackle environmental degradation and climate change must therefore focus on ensuring that ecosystems can respond to high levels of pressure while continuing to provide services indispensable to human development and to life. Evidence is pointing to a bleak outlook if we continue on our current trajectory.

Existe un volumen importante de información que corrobora que en nuestro país el estado de los sistemas hídricos y la calidad de las aguas en zonas rurales sufren crecientes procesos de degradación. Esta degradación es consecuencia, en gran medida, de los impactos de la intensificación agropecuaria.
