The study site (around 60 km * 60 km) is located near Antsirabe, in the Highlands Region of Madagascar. In this region, like in the whole country, the main crop is rice, mainly cultivated under irrigation, on terraces or basins. Nevertheless, rainfed rice started to develop on the hills since the recent spreading of new resistant varieties. Information is missing on cropped surfaces, their distribution and production in a country touched by food insecurity.
