Beyond pastures, look at plastic: Using Sentinel-2 imagery to map silage bags to improve understanding of cattle intensity por Fernandez, Pedro David, Gärtner, Phillipp, Nasca, Jose Andres, Rojas, Tobias, Gasparri, Nestor Ignacio

“…Silage bag mapping is thus an opportunity to improve the overall understanding of livestock intensification and its productive and environmental impacts, particularly in highly seasonal rangelands. Following this metric could be a valuable indicator of the cattle ranching performance in terms of it resilience, production increase and impacts over natural ecosystems (related to Sustainable Development Goal 2-zero hunger and also in the 15-life on land).…”

Defoliation Frequency Effects on Shoots and Roots of Poa ligularis in Arid Patagonia, Argentina por Busso, Carlos Alberto, Gittins Lopez, Cecilia Gabriela, Becker, Guillermo Fernando

“…Poa ligularis is an important forage, perennial bunchgrass in Patagonian rangelands. We hypothesized that (1) root biomass in P. ligularis is not reduced by increased defoliation frequency, as carbon would be allocated similarly above- (for leaf and shoot regrowth) and belowground (to maintain the water uptake necessary for shoot regrowth), and (2) root survival is greater with increasing soil depth in the various defoliation treatments because shallow soils are characteristically more water-limited depending on seasonal precipitation. …”
