IAI-Science-ISP3-077-004:Caracterizacion regional de los recursos forrajeros de las zonas templadas de Argentina mediante imagenes satelitarias
Listed in NASA Earthdata CMR
"A proper management of forage resources needs information on three fundamental characteristics of aboveground net primary production (ANPP): 1) the average ANPP, 2) the average seasonal variation of primary production and 3) the interannual variability of primary production.
Description
We present here an analysis of these characteristics for grasslands and shrublands of temperate Argentina based on the relationship between satellite data and ANPP developed for grassland ecosystems.
ANPP increases gradually from the Patagonian steppes (less than 0.2 Mg.ha-1.year-1) to the Flooding Pampa and Mesopotamic grasslands (more than 6 Mg ha-1.year-1). In most of the systems the average seasonal variation of primary production shows just one peak. The date and length of the peak varied across the region.

The interannual variability of primary production decreases exponentially with increases in average ANPP, suggesting that the relative uncertainty to plan forage uses will be high in the less productive environment. On going research on the use of satellite data will provide better estimates of ANPP and, eventually, will allow for the development of ANPP forecast systems".
