#Horticulture is in serious jeopardy in #Iran, particularly over its #semi-arid and #arid Central Plateau. We used time series of #Landsat, #climate and field #piezometer data to monitor retrospective and #predict future #drought in #pistachio orchards. Link:

Just came across this interesting article reporting an update on #iranveg database, the first national vegetation database in Iran. Access to the database is subject to a formal request to the database manager.
