Floods in Southern Africa |
| Description |
A black web of water surrounds the Zambezi River in the top image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite on February 10, 2007. Mozambique was experiencing its worst floods in six years when the Zambezi flowed over its banks in January and February 2007, reported the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/RWB.NSF/db900SID/YZHG-6YCQR4?OpenDocument&rc=1&emid=FL-2007-000011-ZMB ]). As of February 12, an estimated 29 people had died and 60,000 had been evacuated from the river's banks. Early and heavy rains fell over the entire Zambezi Basin, pushing the Zambezi and many of its tributaries into flood stage. The floods are likely to worsen as the 2,574-kilometer-long river receives water from its swollen tributaries in Angola, Namibia, Zambia, and Malawi. Releases from the massive Cahora Bassa Reservoir, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14110 ] which is reaching its capacity, are also expected to make flooding worse along the lower Zambezi. These images show the lower Zambezi where it meets the Shire River flowing south from Malawi, one of the most severely affected regions in Mozambique. The top image provides a remarkably cloud-free view of the floods, while the lower image, taken on December 31, 2006, shows the region before the rains started in January. The images were made with a combination of infrared and visible light to highlight the presence of water on the ground. Water is black or dark blue, while plant-covered land is green. Bare earth is tan and pink, and clouds are pale blue and white. Fires are outlined in red. Images such as these and photo-like, true-color images are provided by the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_SMozambique/2007041 ] on a daily basis.

Floods in Southern Africa |
| Description |
The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite acquired these two images of the Zambezi River in central Mozambique in February 2007 just four days apart. Over the course of a weekend, floods along the lower Zambezi River in Mozambique spread to a nearby branch, the Cuecue River. According to local news reports released by the Agencia de Informacao de Mocambique, the floods along the Zambezi started to drop on February 20, though water levels on the lower Zambezi, shown here, remained high. As the top image shows, some of the water is draining into smaller offshoots along the river valley and into the Indian Ocean. These images use both visible and infrared light to increase the contrast between water and land. In this color combination, water is black or dark blue, while bare ground is tan and plant-covered land is green. Clouds are blue and white. The Sun's reflection off the surface of the water turns the river pale blue in the top image, and a web of flood water surrounds the dark line cut by the Zambezi River across the center of both images. South of the fresh floods on the Cuecue River, several dark spots along the Zambezi indicate additional flooding. To see daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Mozambique/2007051 ] of the flood area in central Mozambique, please visit the MODIS Rapid Response web site. The floods started when unusually early and heavy rain pounded southern Africa in January and February 2007. The rains triggered floods that affected nearly 170,000 people in Angola, Madagascar, Malawi, Mozambique, Zambia, and Zimbabwe, said the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/RWB.NSF/db900SID/YSAR-6YLNES?OpenDocument ]). In Mozambique, the United Nations and other organizations were providing food to more than 120,000 evacuees as of February 20, said OCHA.

Fires in Angola
| Title |
Fires in Angola |
| Description |
In southern Africa's tropical savannas, fires set by humans are widespread for many months each year. During the dry season, people use the fires to clear brush, pasture, or old croplands, and also to drive game and livestock. In Angola, burning often begins sometime in May and becomes more and more widespread through mid-year, tapering off in September or October. This image of Angola, Democratic Republic of Congo, and Zambia was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on July 9, 2007. Fires (locations marked in red) blanket the scene. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response [ http://rapidfire.sci.gsfc.nasa.gov/ ] team. |

Fires in Central Africa
| Title |
Fires in Central Africa |
| Description |
In Africa south of the equator, fires are ubiquitous during the annual dry season. The exact length and timing of the dry season vary in different locations, but it generally falls between May and October. During that time, people use fire to clear brush and crop stubble, to control the growth of undesirable plants in crop or grazing areas, and to drive grazing animals from one pasture area to another. This image shows early dry-season burning across a large swath of central Africa south of the equator on May 28, 2007. The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite, and shows places the sensor detected active fires marked with red dots. Hundreds of fires dot the tropical savannas (ecosystems dominated by grasses and scattered trees and shrubs) of Angola, Democratic Republic of Congo, and Zambia. Although these fires are not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources. For example, the fires create large amounts of ozone and other air pollutants, and the too-frequent use of fire combined with other pressures such as overgrazing may degrade the soil and prevent some plant species from regenerating. You can download a 250-meter-resolution Central Africa fires KMZ file [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/May2007/cafrica_amo_2007148.kmz ] for use with Google Earth.

Fires in Central Africa |
| Description |
In central Africa the annual fire season was underway in mid-June 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite passed overhead and captured this image. Hundreds of agricultural fires were scattered across the savannas of Angola, Democratic Republic of Congo, Zambia, and Tanzania, their locations are marked with red dots. Although it is not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources.

| Title |
Flooding in the Zambezi Valley |
| Description |
The ribbon of blue flood water that surrounds the Zambezi River in the top image is not unusual. Every year, when the rainy season sets in over southern Angola and western Zambia, the river rises and spreads wide across its flood plain. The intense rains that fell from mid-December through March 2007 caused widespread flooding across southern Africa [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14125 ] from Angola to Mozambique. The floods caused dozens of deaths, displaced thousands, and caused extensive damage to both agriculture and infrastructure, said the Dartmouth Flood Observatory. [ http://www.dartmouth.edu/%7efloods/Archives/2007sum.htm ] Many of the deadly floods have occurred along various sections of the Zambezi and its tributaries. The floods shown here caused agricultural losses. In additional to being heavier than normal, the rains also came early, reported the Dartmouth Flood Observatory. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on March 4, 2007. The lower image was taken on December 1, 2006, by the MODIS sensor flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, and is provided here to show the river during the dry season. The images were made with visible and infrared light to highlight the presence of water on the ground. Water is dark blue, while the surrounding plant-covered land is green. Bare or lightly vegetated ground is tan, and clouds are pale blue and white.
