Perspectives on Rangeland Management Education and Research in Argentina

Economics of Land Degradation in Argentina

“…TME is a grazing plan developed after remote sensing assessment is done to determine the carrying capacity. The farmer is advised to manage grazing such that half of aboveground biomass preferred forage is left before animals are moved to another paddock (Anderson et al 2011).…”

“…In drier areas, livestock movement during this time is harder (ii) animal movement increases mortality of lambs and therefore is not preferable to farmers (iii) a cultural system of uncontrolled grazing is the major constraint to adoption of rotational grazing. For example, due to the strongly held traditional continuous grazing systems, only 6 % of sheep farmers in southern Patagonia have adopted TME (Anderson et al 2011). Below, we discuss a case study in Jacobacci to better understand the impact of land degradationand climate change.…”

“…This has led to migration of some sheep farmers to urban areas and job losses of farm workers. To address land degradation, the TME recommendation has been given but its adoption rate remains low (Anderson et al 2011). Diversification to wool and mutton (meat sheep) has also been one of the strategies to address the falling wool price.…”

Preselección De Germoplasma De Macroptilium Lathyroides (L.) Urb. Con Tolerancia Al Sombreado

“…La producción ganadera extensiva del centro-norte de Argentina se sustenta, principalmente, de los pastizales naturales (Anderson et al, 2011). Parte de estos pastizales ocurren en sectores de bosques, donde los planteos silvopastoriles, fundamentalmente para ganadería de cría, es la actividad productiva dominante.…”

Bases para una ley de pastizales de regiones áridas y semiáridas de la Argentina

“…Esta propuesta focaliza en los pastizales ubicados en regiones áridas y semiáridas (0.05<Índice de Aridez<0.5) (Reynolds et al 2007), que representan el 65% de la superficie global de las tierras secas (Safriel and Adeel 2005), y ocupan una proporción significativa del territorio de la Argentina. Su relevancia radica en que son fuente de múltiples servicios ecosistémicos de alto valor para la sociedad, tanto local como globalmente (Anderson et al 2011). En particular, proveen de forraje para el ganado, fuente de calor en viviendas (Cardoso et al 2012), flora ornamental y usos medicinales (Ladio and Lozada 2009).…”
