Summary
La intensificación agraria transforma el territorio y amenaza la actividad de ganaderos familiares que alternan el pastoreo dentro y fuera del área protegida Esteros de Farrapos (APEF), en lãs inundaciones. Con el objetivo de analizar la disponibilidad real de tierras de pastoreo en la cuenca Del APEF, se evaluó entre 1998/2011: el cambio de uso del suelo, la intensificación con un índice de intensificación, en cuenca, planicies bajas y paleocosta; la diversidad estructural con el índice de Shannon, la variación de superficie del pastizal, su fragmentación y dispersión con el índice de Moran y las distancias de remanentes de pastizal al APEF. En 13 años, los usos menos intensivos pasaron de 60 a 20 % y los más intensivos de 40 a 80%. Tomando como base 1998, los bosques disminuyeron 92% y el pastizal 52%. La diversidad estructural disminuye, el pastizal se fragmenta y dispersa. Los remanentes de pastizal próximos al APEF son pequeños y dispersos. Los indicadores muestran la dinámica de intensificación. Desde la Agroecología se cuestiona el uso del territorio que separa producción – conservación, para plantear su integración.
Summary translation
Agricultural intensification has generated deep territorial transformations in Uruguay. It has decreased grazing lands and is threatening the activity of small livestock producers who alternated grazing in and out of the protected area, and are now facing conservation requirements within the area and a land decrease outside it. It is described the change in the basin as a factor of threat, evaluating, during 1998–2011, the intensification and structural diversity, as well as variation in pasture area and its fragmentation. The intensification was evaluated through an intensification index, the structural diversity using the Shannon index and the dispersion of grassland by the Moran index. In 1998, 60% show less intensive uses, and 40% more intensive uses. In 2011, this ratio changed to 20% and 80% respectively, forestry decreased 92% and grasslands 52%. The basin’s structural diversity decreases, grassland is fragmented and dispersed. Indicators show the dynamics of intensification and the actual decrease in grazing lands. From Agroecology, it is discussed land use which separates production-conservation, to raise one that integrates both functions.
