Below-average rains began in late 2011 and resulted in drought conditions across the Sahel early in 2012. Based on poor vegetation growth, higher food prices, poor crop yields, and regional violence, there are predictions of widespread food insecurity throughout the region - with a particular focus on Mauritania, Mali, Burkina Faso, Niger, and Chad. Recent reports from UN have shown increased population movements in the region due to violence in Mali1. In areas where food insecurity and malnutrition are already chronic, there are predictions that food insecurity will grow as populations try to cope with the continuing drought conditions. The UN estimates over 15 million people are at risk2.
Rains only come once a year in the Sahel, last year they were below-average. Over 15 million people are at risk for food insecurity. In an effort to respond to early warnings, this tool is a collaboration to strengthen the data sharing in the region.

Description
This map summarizes the number of vegetation growing seasons affected by poor vegetation growth between 2006 and 2010, supporting the definition of the most vulnerable areas. Information has been extracted from MODIS NDVI time-series (2000-2010), only considering the first (or main) growing season for considered years and using the Seasonal Small Integral parameter in order to describe vegetation productivity. Pixel based results are proposed (0.05 degrees). Further information can be found on the ITHACA website.

This map shows the current vegetation growth deviations for the 2011 season by second-level administrative divisions. Information has been extracted from MODIS NDVI time-series (2000-2010), only considering the first (or main) growing season for considered years and using the Seasonal Small Integral parameter in order to describe vegetation productivity. Pixel based results are proposed (0.05 degrees). Results here are summarized using second-level administrative boundaries. Further information can be found on the ITHACA website.
