The aboveground net primary productivity ( ANPP) of bofedales is one the most important indicators for provision ecosystem services in high Andean areas. In case bofedales, evaluation ANPP supply capacity as a service on spatial and temporal scale through remote sensing has been little addressed. capacity, intra interannual, to provide wetlands was quantified at level sensing. normalized difference vegetation index NDVI) MODIS sensor used according Monteith model (1972), product incident photosynthetically active radiation, fraction absorbed efficiency using radiation calibrated with dry matter sampling field. Results show an prediction R 2 0.52 (p < 0.05), no significant between field samples. When applying model, intra-annual temporary presents maximum average 160.54 kg DM·ha –1·month –1 rainy season (December–May) 81.17 (June–October). 2003–2020, interannual presented values 1100–1700 –1·year –1. This makes it possible not affect sustainability prevent their depletion degradation. Understanding can favour efficient use resource indirectly benefit its conservation.
