Where? When? How much? These are some of the most frequently asked questions about rice cultivation that we face as part of the GIS lab team at the International Rice Research Institute. In the last issue, we featured a global perspective on the rice calendar. Here, we zoom in on the details in the major rice-growing areas of Luzon, Philippines. These 12 maps—derived from satellite images—show the progression of the rice crop month by month. The areas in blue are freshly planted and the areas in green are mid- or late-season rice. The areas in light gray show the maximum extent of rice grown in Luzon. The dry-season crop is planted in December to January (blue). Most rice crops are well established (green) by March and are harvested in April or May.
