Half-dry ISDN: average vegetation indices for the month of March 2008 for rain-fed and grassland areas
Description
The data set of monthly average vegetation indexes of the month of March 2008 of NDVI of rainfed (Normalized Difference Vegetation Index) of the study of Monitoring of the Annual Evolution of crops and Harvests represents the vegetation indexes with the average value of the month of March, obtained in the agricultural campaign of 2008, for the entire area of rainfed land and grasslands of the regions studied.
These monthly average indices intersect with thematic cartography and are compared with the average monthly data of the historical series.
To obtain these results, the Ministry of Agriculture and Fisheries, Food and Environment (MAPAMA) has a system for monitoring the evolution of rainfed crops and grasslands, based mainly on the information provided by vegetation indices (NDVI) generated with daily satellite images NOAA-AVHRR. This system has been in operation since 1993, paying particular attention to the detection and localization of drought situations throughout the successive agricultural years, in order to provide for the necessary measures to be taken to mitigate its effects. The system is in operation between the months of January and June, the period in which the studied crops are developed.
The study is carried out in the autonomous communities of Navarra, Aragón, Cataluña, Castilla y León, La Rioja, Madrid, Castilla-La Mancha, Comunidad Valenciana, Andalucía, Región Murciana, Extremadura and Baleares, as they comprise almost all rainfed crops and grasslands.
