      On October 31, 2022, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Aqua satellite acquired a true-color image of   
      central Mali, showing the Inland Niger Delta wetlands flush with   
      vegetation after a long and wet rainy season. Each year, this   
      emerald-colored jewel fills with floodwaters from the Niger River, the   
      Bani River, and a network of smaller streams during the wet season   
      (July through October), growing to about 7,700 square miles (20,000   
      square kilometers). As rains cease and the dry season progresses,   
      rising temperatures speed evaporation to shrink this inland delta to   
      about 1,500 square miles (3,900 square miles).   
      
      In typical years, the inundated delta attracts a wide array of animals   
      and birds to the freshened wetlands, while the waters help fertilize   
      soils and aid farming efforts in the region. Unfortunately, 2022 was   
      not a typical year in the Central Sahel. According to the United   
      Nations High Commissioner for Refugees (UNHCR), in the countries of the   
      Central Sahel (Niger, Mali, and Burkina Faso), above-average rains and   
      floodings brought disaster to residents, and “have killed hundreds,   
      displaced thousands, and decimated over one million hectares of   
      cropland.” They estimate that more than 41,000 people have been   
      affected by the excess flooding throughout Mali. In 2021, damaging   
      flooding affected 10,511 people in the same region.   
      
      The true-color image, above, effectively shows a snapshot of Mali on a   
      single overpass on a single day. Sometimes, especially with cyclical   
      changes that affect a region, much more information can be gleaned from   
      looking at changes over time. The NASA Worldview app makes comparisons   
      quick and easy.

      region simply click here . The first image is our Image of the Day   
      collected on October 31, 2022, at the end of the wet season. The other   
      was acquired on June 2, 2022, at the end of the dry season and before   
      rains began. The difference is dramatic.
