Dust Plumes over Algeria and Niger |
| Description |
Plumes of dust blew through Algeria and Niger on July 31, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture the same day. In the northern- and easternmost portions of this image, buff-colored blurs of dust hide the landscape below. Where dust is absent, the ground appears in shades of tan and brown, with sharp ridges appearing in places. Where it hovers over the land, the dust plume presents a uniform color. Bright white clouds float above the plumes of dust. NASA image courtesy the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC.

Dust Storm from the Sahara Desert |
| Description |
On February 21, 2007, a dust storm several hundred kilometers across clogged the skies over Algeria and Mali. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite took this picture the same day. This image shows the dust cloud over the Sahara Desert. As the dust is only slightly lighter than the sand below, the storm is easiest to discern in the east, over more variegated terrain. The Sahara Desert ranks unsurprisingly among the world's most dust-prone regions. Dust from this desert not only crosses national boundaries, but can also travel across the Atlantic Ocean to the Caribbean.

Locusts Plague Northwest and
…
| Title |
Locusts Plague Northwest and Western Africa |
| Description |
A wet winter and spring settled over northwestern Africa in 2004, and the dry Sahel bloomed with life. As the desert turned green, the plentiful water nourished more than vegetation. Buried in the sandy soils were the eggs of desert locusts, waiting to absorb moisture and hatch. This year, there was enough water and vegetation to support large populations of young locusts, and by late summer, several large swarms had developed. Swarms of locusts can contain as many as 80 million locusts per square kilometer, and may cover several square kilometers. An adult locust can eat its own weight in food every day, about two grams, which means that, according to the Food and Agriculture Organization (FAO) of the United Nations, a small part of a typical swarm can eat as much food as 2,500 people in a single day. At these rates, the locusts consume most vegetation in their path and then must migrate to find new sources of food. The locust outbreak of 2004 began in Morocco and Algeria in northwestern Africa. While the locusts can't be seen in satellite imagery, the conditions that support them are clearly visible. The above image shows how vegetation differed from previous years. The image is a composite of Normalized Difference Vegetation Index (NDVI) data collected between April 6 and April 13, 2004. Green areas indicate that there was more vegetation in the region than the average of the past four years. Not surprisingly, these areas correlate well with the early breeding grounds of the locusts near the interface between dry desert land and wetter coastal land. When their numbers and the ending growing season forced the locusts to move, they traveled south and east on the summer winds. As of October 5, the locusts had expanded to the south in a band that stretched from Mauritania to Chad?a distance of roughly 4,000 kilometers. Currently, Mauritania is the worst affected, but Senegal, Mali, Burkina Faso, Niger, Chad, and the Cape Verde Islands have also been plagued with locusts. The swarms are now starting to move north again, this time into Libya and Algeria. On October 1, three to four million hectares of land were infested with locusts. As before, satellite imagery shows where locust swarms can migrate to find food by indicating where food is available. In the lower image, a composite of data collected between August 28 and September 4, 2004, pockets of green in southern Mauritania, Senegal, Mali, and Burkina Faso show where the locusts are finding food and breeding. The most recent information from FAO shows that these are indeed the areas where the locusts are concentrated. Though the locusts themselves are harmless, they can cause significant crop damage. The worst of the problem is in Mauritania, where dark clouds of locusts have swarmed over much of the country. Rainfall had been good, and farmers anticipated a better-than-average harvest until the locusts arrived. Mauritania?s national food security authority expected to lose up to 75, percent of the cereal crop, though the Food and Agriculture Oragnization (FOA) of the United Nations expected a smaller loss. Undoubtedly, the insects are causing considerable damage, but both the Foreign Agricultural Service [ http://www.fas.usda.gov/pecad/highlights/2004/08/west_africa/index.htm ] of the United States Department of Agriculture and the FAO say that it?s too early to quantify how the outbreak will impact overall production. Harvest began in September and continues through November, and the amount of crops that the locusts consume in the meantime will depend on how effective efforts to control them are and whether or not the locusts continue to breed. To read more about the current locust situation in Africa, please visit the Desert Locust Information Service [ http://www.fao.org/news/global/locusts/locuhome.htm ], a service provided by the Food and Agriculture Organization of the United Nations.

Saharan Dust Across West Afr
…
| Title |
Saharan Dust Across West Africa |
| Description |
A long line of Sahara dust swept across Mali, Mauritania, and Western Sahara and out over the Canary Islands on March 3, 2004. The dust appears to have originated in Algeria. Winter and spring dust storms are common in Western Africa when the sirocco winds, hot, dry, dust-laden winds, blow north and northwest out of the Sahara desert. This image was taken by the Terra [ http://terra.nasa.gov/ ] satellite. Later on the same day, the Aqua [ http://aqua.nasa.gov/ ] satellite recorded a similar scene. As the day progressed, the dust grew thicker and the storm extended farther west. The high resolution image provided above is at MODIS' maximum resolution of 250 meters per pixel. The scene is available in additional resolutions. Image courtesy Jacques Descloitres, MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC |

Saharan Dust over Italy |
| Description |
*Saharan Dust over Italy* A thick plume of Saharan Desert dust blew toward the northeast over Algeria and Tunisia and across the Mediterranean Sea on February 22, 2004. The dust was so thick it almost completely obscured the view of the surface in this true-color image acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite. The path of the dust storm carried it directly over the island of Sicily and Italy's southern mainland. The tan color of the dust makes it easy to distinguish from the much brighter, white clouds in the scene. The high-resolution copy of the image above is 500 meters per pixel. This scene is also available at additional resolutions. Image courtesy Jacques Descloitres, MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC |

Snow over Northern Africa
| Title |
Snow over Northern Africa |
| Description |
Winter weather descended on Northern Africa on January 26 and 27, 2005, leaving parts of Algeria and Morroco white with snow. This rare storm—the worst in over 50 years—brought chaos to the roadways of the normally arid region. As the clouds began to move away on January 28, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured these images of the snow. The top image shows the region in true color, as the human eye would see it. In this image, light clouds blend with the snow-covered ground, making it difficult to tell how much snow is present. The lower image shows the same scene in both visible and short wave infrared light. The infrared bands separate cloud and ice, with cloud appearing peach and orange, and ice and snow appearing dark red. Vegetation is a dark green, while the bare desert is turquoise. In this image, the snow extends from the Mediterranean Coast in the north to the northern reaches of the Sahara Desert in the south.

Both the true and false color images are available in additional resolutions. |

Flooding in Algeria

Flooding in Algeria |
| Description |
Heavy rains in eastern Algeria over the past few weeks have led to flooding that has killed more than 30 people and left hundreds homeless. This false-color image of Algeria (bottom) was taken on August 29, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra satellite. Most of the deaths were due to flash floods in the towns along the Algerian-Tunisian border, which runs down the center of the image. These floodwaters have made their way to the low-lying, desert wetlands of Algeria, clearly visible in the MODIS image (bottom). Although water levels have gone down over the past two days in these oasis-like formations, they normally cannot be seen at all in MODIS imagery (top, acquired on August 6, 2002).

Flooding in Tunisia |
| Description |
In early January 2003 heavy rains in Tunisia have led to floods that have displaced over 3,000 people. The floods can be seen in this false-color image (bottom) acquired on January 19, 2003, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Terra spacecraft. The most devastating floods occurred in the northern and central parts of Tunisia. Most of the houses affected were built of soil and provided ample protection from the normally hot, arid conditions. In the unusually heavy rains and floods of the past few weeks, however, these dwellings simply crumbled. Cattle and food stocks have also been lost. Normally, the salt pans of Tunisia and Algeria contain little or no water (top, acquired January 4, 2003). In this false-color image water is blue and black. Snow, which has also fallen in unusual abundance in the higher altitudes, appears as a bright cyan and can be seen along the Algeria mountains and ridges. Clouds appear as pale blue and white, and land is green and tan. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC |
