Widespread agricultural burn
…
7/24/09
| Description |
Widespread agricultural burning is common in the dry season in Africa. As the rainy season migrates north and south across the continent each year, a wave of widespread fires precedes its arrival. This image of the Kasai region of Democratic Republic of the Congo shows hundreds of active fires (marked in red) burning on July 20, 2009. The tan and light green landscapes are likely a mixture of agricultural land, grassland, and savanna, while the deep green areas between the Sankuru and Kasai Rivers are tropical forest. Although many of the fires that occur each year during Africa's dry season occur in landscapes where people have been living and farming for generations, the growing population is also using fire to clear new agricultural land out of Africa's tropical forests. Many of the fires in the image have only small smoke plumes, and some appear to be making no smoke. Dry grass or crop residue would generate less smoke than live or recently cut trees. The large amount of smoke coming from the fires along the margins of the forests, however, may indicate that forest is being cleared. The large version of the image shows fires are burning across a wider area, including parts of Angola (southwest), Zambia (southeast), and Tanzania (east). The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite.

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.

The agricultural burning season was solidly underway in central Africa on May 18, 2005, when this image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua satellite. Each red dot in this image marks a location where MODIS detected a fire. Fires are scattered across much of Angola, Democratic Republic of Congo, and Zambia. The widespread nature of the fires, their location, and the time of year all suggest that people are intentionally setting most of these fires for agricultural purposes. Though not necessarily hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources.

Fire Season in Central and Southern Africa |
| Description |
The annual southern Africa burning season is fully underway in late July 2005. Each year, farmers and herders set fire to fields and grasslands to create soil-fertilizing ash, stop woody shrubs from encroaching on grasslands, and stimulate new plant growth. For those who don't live or travel there, it can be hard to imagine a continent on fire from coast to coast for several months a year. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite shows the immense spatial scale of the seasonal burning in Southern Africa. Thousands of active fires were detected by MODIS across Angola (left), Democratic Republic of Congo (top), and Zambia (right), their locations are marked with red dots. Though these fires are not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources.

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 in Central Africa |
| Description |
The fire season in central Africa roared to life in the first week of May. When the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua satellite passed over the region on the afternoon of May 6, 2004, it captured this image along with nearly 4,000 fire detections (marked in yellow) in southern Democratic Republic of Congo (top right) and northern Angola (bottom left). Each year, the region experiences widespread agricultural burning (for example, pasture renewal and land clearing.) The widespread nature of the fires pictured here and the time of year suggest that the fires are being set intentionally for agricultural purposes. Though not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources.

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.

MODIS also detected fires (locations marked in red) in Zambia (bottom right). Widespread agricultural burning (clearing old vegetation or brush from pasture and croplands) occurs in the dry season in this part of Africa. The start and stop date of the dry and rainy seasons varies, in northern Angola, for example, the dry season usually begins in May and lasts until September or October. Fires are a well-established, and in many cases natural, part of the savanna landscapes of Africa south of the Sahara.

On July 10, 2006, thousands of fires were burning across the savannas of central and southern Africa when the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite passed overhead. Each place where MODIS detected an actively burning fire has been marked in red in this scene, which spans parts of Angola, Democratic Republic of Congo, and Zambia. Some of the fires had distinct smoke plumes, which winds were blowing northwest. At upper left, the skies are so smoky that the features of the landscape below are indistinct. Even the clouds in the scene at left and upper right appear dirty. No landscape on Earth experiences such extensive burning as the savannas of Africa. For thousands of years, people in Africa have used fire in their agricultural activities. They burn grassland to clear it for crops, to keep woody plants and trees from invading pasture areas, and to renew pasture grass. People have also used fire to drive game and facilitate hunting. Although fire has been integral to the ecosystems of southern Africa for millennia, increasing populations and demands on the landscape may change the frequency and intensity of burning. Such widespread burning, while not necessarily immediately hazardous, can have a strong impact on climate, human health, and natural resources.

South of the Sahara Desert, agricultural burning dominates the savanna landscape in Africa in the dry season. Vast areas of the continent burn every year as people set fire to range and crop lands to clear or renew them for the next growing season. A clear day over central Africa on July 30, 2006, revealed the widespread areas burned by agricultural fires so far this season. 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 it uses MODIS' observations of shortwave and near-infrared light along with visible light to make the burned areas stand out from unburned vegetation. Across Angola, Democratic Republic of Congo, and Zambia, deep red burn scars mingle with the unburned bright green vegetation. Water is dark blue, and naturally bare or sparsely vegetated ground appears light (sometimes pinkish) tan. Places where MODIS detected actively burning fires are marked in red.

Seasonal floods along the Zambezi River |
| Description |
Heavy rains through the month of March have pushed a section of Africa?s Zambezi River to its highest level since 1958. Just as the mighty river turns east in its path to the Indian Ocean, and immediately before it thunders over the Victoria Falls, it passes through the low-lying plains of Namibia?s Caprivi Strip. This section of the river floods often as the wet-season rains fill the river. This year, the floods have come earlier than normal, and are rising to levels not seen in nearly 50 years. The Namibian government expects to evacuate 40,000 to 50,000 people from the region as the flood waters continue to rise, though only 20,000 have been affected as of April 1. In comparison, last year?s floods, which at the time were declared the worst the region had seen since 1958, forced 12,000 people from their homes. On March 31, 2004, the waters reached 6.89 meters, surpassing the peak of last year?s flood, 6.64 meters. So far, two people have died in this year?s floods. The Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) on the Aqua [ http://aqua.nasa.gov/ ] satellite captured this view of the flood in the Caprivi Strip on March 30, 2004. The false color image shows the flood water in an inky black in sharp contrast to the bright green vegetation. Bare ground is tan and clouds are light blue. The image is available in true-color [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004090-0330/Caprivi.A2004090.1205 ] and additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004090-0330/Caprivi.A2004090.1205.721 ]. The Zambezi River forms at a spring in northern Zambia, and flows south through Zambia and Angola before turning east in Namibia?s Caprivi Strip and flowing through Zimbabwe, Zambia, and Mozambique to the Indian Ocean. It is Africa?s fourth largest river system after the Nile, Zaire, and Niger Rivers. The high-resolution image also shows floods along the northern section of the river in Zambia at MODIS maximum resolution of 250 meters per pixel.

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.

Flooding on the Zambezi River |
| Description |
Nearly every April, Africa's Zambezi River swells with seasonal rain, spreading across its broad flood plain in Angola and Namibia. Some of the people most seriously affected by the regular floods live in Namibia's Caprivi Strip. As of April 11, 2006, seven settlements in the flood-prone region were surrounded by water, reported the New Era, a Namibian newspaper. The region was clearly flooded in a false-color satellite image taken on April 11 (top), by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. In this image, water is black and dark blue, clouds are pale blue, plant-covered land is green, and bare earth is tan. In the three and a half weeks that passed between the time the top image was acquired and the time the lower image was acquired, the eastern tip of the Caprivi Strip turned into a vast shallow lake. Though the river was still rising, the floods were nowhere near the record-setting levels seen in 2004 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12081 ].

Flooding on the Zambezi Rive
…
| Title |
Flooding on the Zambezi River |
| Description |
Nearly every April, Africa's Zambezi River swells with seasonal rain, spreading across its broad flood plain in Angola and Namibia. Some of the people most seriously affected by the regular floods live in Namibia's Caprivi Strip. As of April 11, 2006, seven settlements in the flood-prone region were surrounded by water, reported the New Era, a Namibian newspaper. The region was clearly flooded in a false-color satellite image taken on April 11 (top), by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. In this image, water is black and dark blue, clouds are pale blue, plant-covered land is green, and bare earth is tan. In the three and a half weeks that passed between the time the top image was acquired and the time the lower image was acquired, the eastern tip of the Caprivi Strip turned into a vast shallow lake. Though the river was still rising, the floods were nowhere near the record-setting levels seen in 2004 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12081 ].
