In Saudi Arabia, center-pivot, swing-arm irrigated agriculture complexes such as the one imaged at Jabal Tuwayq (20.5N, 45.0 E) extract deep fossil water reserves to achieve food crop production self sufficiency in this desert environment. The significance of the Saudi expanded irrigated agriculture is that the depletion of this finite water resource is a short term solution to a long term need that will still exist when the water has been extracted.

STS035-73-082 (2-10 Dec 1990) --- This agricultural and ranching area, Rio Sao Francisco, Brazil (13.0S, 43.5W) has been under study for several years. See scene STS-31-92-045 for comparison. This area has many small single family subsistence farms, large square and rectangular commercial farms and pastures for livestock grazing. Over the several years of observation, the number and size of farms has increased and center-pivot, swing-arm irrigation systems have been installed.

Agriculture aircraft in Full Scale Tunnel (FST). -- Photographed on: 05/19/78.

The large field patterns in this view of the Rio Sao Francisco basin, Brazil, South America, (11.5S, 43.5W) indicate a commercial agriculture venture; family subsistence farms are much smaller and laid out in different patterns. Land clearing in Brazil has increased at an alarming rate in recent years and preliminary estimates suggest a 25 to 30% increase in deforestation since 1984. The long term impact on the ecological processes are still unknown.

Stark effects of a California drought on agriculture can be clearly seen in these two February images acquired in 2014 and 2003 by NASA Terra spacecraft.

iss072e574769 (Jan. 29, 2025) --- Agricultural activity, supported by the Toshka Lakes created by the overflow from nearby Lake Nasser in Egypt, is pictured from the International Space Station as it orbited 259 miles above.

This near vertical photograph illustrates the differences in agricultural land patterns typically seen in many parts of southwestern Brazil, near the Bolivian border. The larger rectangular field patterns reflect a mature, fully developed agricultural environment. The smaller areas are less well defined and indicate new agricultural development.

Evidence of a recent flash flood can be seen in the form of light brown sediment that flowed down gullies and mountain sides forming ponds of debris over agricultural areas in the broad valley near the town of Parras (26.5N, 102.5W). This part of Mexico has extensive vineyards, orchards and both dry land and irrigated agriculture. Based on the photo, it appears that flash flood waters damaged some 300 square miles of property in this area alone.

iss073e1197819 (Nov. 22, 2025) --- Myanmar’s (Burma) Irrawaddy Delta—an important agricultural region in Southeast Asia filled with mangrove forests, rice paddies, and swampy lowlands—empties into the Andaman Sea and is pictured from the International Space Station as it orbited 262 miles above.

Agricultural patterns are distinctly visible in this near-vertical false color infrared photography taken in November 1994. The area depicted on the photograph is south of Khartoum between the White and Blue Nile Rivers. By far the most important irrigation project in sub-Saharan Africa, both large and small scale agricultural enterprises have been developed using water transported from the perennial Nile Rivers. Hundreds of small rectangular fields and water-filled canals can be seen in this photograph.

SL2-03-200 (22 June 1973) --- The city of Phoenix, AZ (33.5N, 112.0W) can be seen in good detail in this color infrared scene. Situated among truck crop agriculture fields, the color infrared photo depicts the vegetated fields as shades of red making the agriculture stand out in this desert environment. To the east, Lake Theodore Roosevelt and dam can be easily seen. Photo credit: NASA

SL2-10-250 (May-June 1973) --- A vertical view of eastern Iowa and northwestern Illinois, as photographed from Skylab space station in Earth orbit. Davenport, Burlington and Muscatine, Iowa; and Rock Island and Moline, Illinois can be delineated on opposite sides of the Mississippi River. The Iowa River and tributaries of it can also be delineated. This photograph was taken with one of six lenses of the Itek-furnished Multispectral Photographic Facility Experiment S190-A mounted in the Multiple Docking Adapter (MDA) of the space station. A six-inch lens, using 70mm medium speed Ektachrome (SO-356) film, was used. Agencies participating with NASA on the EREP project are the Departments of Agriculture, Commerce and Interior; the Environmental Protection Agency and the Corps of Engineers. All EREP photography is available to the public through the Department of Interior's Earth Resources Observations Systems Data Center, Sioux Falls, South Dakota, 57198. Photo credit: NASA

This view of deforestation in Rondonia, far western Brazil, (10.0S, 63.0W) is part of an agricultural resettlement project which ultimately covers an area about 80% the size of France. The patterns of deforestation in this part of the Amazon River Basin are usually aligned adjacent to highways, secondary roads, and streams for ease of access and transportation. Compare this view with the earlier 51G-37-062 for a comparison of deforestation in the region.

STS060-92-082 (3-11 Feb 1994) --- This cloud-free view is centered on the city of Baghdad, Iraq. Baghdad has had a reputation for scholarship and learning from ancient times in the Islamic world. Modern Baghdad is a city with a typical urban land use patterns. The color of Tigris river flowing through the city indicates the heavily sediment laden waters of the river. Agricultural land uses are evident in the surrounding areas of the city.

Mt. Pinatubo on the island of Luzon (15.0N, 120.0E) erupted catastrophically in June 1991 after over 600 years of inactivity. In this vertical view, the full extent of the eruption is obvious. Thick layers of ash completely surrounds the crater and the effect of mudflows in this previously heavily forested and agricultural region can be traced as ribbons flowing downhill. Clark AFB, once the crossroads of the SW Pacific can only partially be seen.

Often, the names of features on planetary bodies are connected through a specific theme -- for example, many features on the Moon have been named after famous scientists. NASA's Dawn mission, together with the International Astronomical Union, established that craters on Ceres would be named for agricultural deities from all over the world, and other features would be named for agricultural festivals. Ceres itself was named after the Roman goddess of corn and harvests by its discoverer, Giuseppe Piazzi, who spotted it with his telescope in 1801. Since March 2015, Dawn has been orbiting Ceres and sending back many intriguing images and other data about its features. Using suggestions from the Dawn team, the IAU recently approved 25 new Ceres feature names tied to theme of agricultural deities, marked in yellow on the map. Emesh Crater, for example, is named for the Sumerian god of vegetation and agriculture. Jumi is the Latvian god of fertility of the field. The newly named surface features vary in size. Thrud, for example, is a crater with a diameter of 4.8 miles (7.8 kilometers) within the larger crater Zadeni, while Mlezi has a diameter of 28 miles (42 kilometers). For more information, the characteristics of these and other features on Ceres can be found in the IAU's Gazetteer of Planetary Nomenclature. https://photojournal.jpl.nasa.gov/catalog/PIA21755

STS054-152-189 (13-19 Jan. 1993) --- This near-vertical color photograph shows the very diverse landscape that is part of the great Sahara Desert of north Africa. Specifically, the vast expanse of sand dunes, located in the extreme southwestern corner of Libya, is known as the Murzuk Sand Sea. Close inspection of this photograph shows the agricultural village of Murzuk as evidenced by the numerous center pivot irrigation patterns at the edge of the Murzuk Sand Sea. The very rugged, dissected terrain to the west of this sand sea is the eastern tip of the Tassili N'ajjer Mountains and the Tadrart Plateau that are in neighboring Algeria. Several smaller areas of sand dunes are interspersed between the major areas of rock outcrops. The photograph was taken with a Linhof camera.

This oblique view of Lake Chad was taken by the STS-66 crew in November 1994. This lake lies mainly in the Republic of Chad and partly in Nigeria, Cameroon and Niger. The size of Lake Chad varies seasonally and is actually divided into north and south basins; neither of which is generally more than 25 feet (7.6 meters) deep. In this photograph, all the water appears to be located in the southern basin with the northern and eastern edges of both basins covered with sand dunes which have invaded the area where the water once stood. The prevailing wind direction can be seen from the agriculture burning in both basins to be from the east.

Achita Crater on Ceres was named for the Nigerian god of agriculture. NASA Dawn spacecraft took this image of the crater on January 15, 2016. Achita is located in the northern hemisphere.

Located in the fertile agricultural region of Argentina Pampas is a guitar-shaped forest made up of cypress and eucalyptus trees as seen by NASA Terra spacecraft.

The Central Valley, CA is one of the most productive agricultural regions in the United States and the world. As California is in a continuing drought, it is important to monitor agricultural plant life to ensure maximized productivity. ECOSTRESS has the ability to monitor Evapotranspiration over agricultural fields. This Evapotranspiration image was captured by ECOSTRESS on May 22, 2022 at 06:04 PM PDT. Blue indicates high water use while brown indicates dry conditions. ECOSTRESS is a thermal instrument on the International Space Station that measures the temperature of the ground, which is hotter than the air temperature during the day. It was launched to the space station in 2018. Its primary mission is to identify critical thresholds of water use and water stress in plants and to detect the timing, location, and predictive factors leading to plant water uptake decline and/or cessation. The nature of the high-resolution data provided by ECOSTRESS allows it to record heat related phenomena such as heat waves and wildfires. https://photojournal.jpl.nasa.gov/catalog/PIA25488

Rectangular fields of the agriculturally rich Santa Clara River Valley are visible in this perspective view generated by using data from the Shuttle Radar Topography Mission and an enhanced Landsat image.

Acquired by NASA Terra spacecraft on in 2011, this image shows the Wadi As-Sirhan Basin in northwest Saudi Arabia, which has been steadily developing agricultural fields using center pivot irrigation by tapping into fossil ground water.

On Oct. 25, 2011, the Chao Phraya River was in flood stage as NASA Terra spacecraft imaged flooded agricultural fields and villages depicted here in dark blue, and the sediment-laden water in shades of tan.

This image captured by NASA Terra spacecraft is of the Jizzax Province in eastern Uzbekistan, one of the main agricultural regions of the country. Uzbekistan is the world sixth largest producer and second-largest exporter of cotton.

STS059-S-086 (18 April 1994) --- This is a three-frequency false-color image of Flevoland, the Netherlands, centered at 52.4 degrees north latitude, and 5.4 degrees east longitude. This image was acquired by the Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the Space Shuttle Endeavour on April 14, 1994. It was produced by combining data from the X-Band, C-Band and L-Band radar's. The area shown is approximately 25 by 28 kilometers (15 1/2 by 17 1/2 miles). Flevoland, which fills the lower two-thirds of the image, is a very flat area that is made up of reclaimed land that is used for agriculture and forestry. At the top of the image, across the canal from Flevoland, is an older forest shown in red; the city of Harderwijk is shown in white on the shore of the canal. At this time of the year, the agricultural fields are bare soil, and they show up in this images in blue. The changes in the brightness of the blue areas are equal to the changes in roughness. The dark blue areas are water and the small dots in the canal are boats. This SIR-C/X-SAR supersite is being used for both calibration and agricultural studies. Several soil and crop ground-truth studies will be conducted during the Shuttle flight. In addition, about 10 calibration devices and 10 corner reflectors have been deployed to calibrate and monitor the radar signal. One of these transponders can be seen as a bright star in the lower right quadrant of the image. This false-color image was made using L-Band total power in the red channel, C-Band total power in the green channel, and X-Band VV polarization in the blue channel. SIR-C/X-SAR is part of NASA's Mission to Planet Earth (MTPE). SIR-C/X-SAR radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-Band (24 cm), C-Band (6 cm), and X-Band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory (JPL). X-SAR was developed by the Dornire and Alenia Spazio Companies for the German Space Agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian Space Agency, Agenzia Spaziale Italiana (ASI).

SL4-92-300 (February 1974) --- A near vertical view of the Mobile Bay, Alabama area is seen in this Skylab 4 Earth Resources Experiments Package S190-B (five-inch earth terrain camera) photograph taken from the Skylab space station in Earth orbit. North of Mobile the Tombigbee and Alabama Rivers join to form the Mobile River. Detailed configuration of the individual stream channels and boundaries can be defined as the Mobile River flows into Mobile Bay, and thence into the Gulf of Mexico. The Mobile River Valley with its numerous stream channels is a distinct light shade in contrast to the dark green shade of the adjacent areas. The red coloration of Mobile Bay reflects the sediment load carried into the Bay by the rivers. Variations in red color indicate sediment load and the current paths within Mobile Bay. The waterly movement of the along shore currents at the mouth of Mobile Bay is shown by the contrasting light blue of the sediment-laden current and the blue of the Gulf predominately. Agricultural areas east and west of Mobile Bay are characterized by a rectangular pattern in green to white shades. Color variations may reflect the type and growth cycle of crops. Agricultural areas (light gray-greens) are also clearly visible in other parts of the photograph. Interstate 10 extends from near Pascagoula, Mississippi eastward through Mobile to the outskirts of Pensacola, Florida. Analysis of the EREP photographic data will be undertaken by the U.S. Corps of Engineers to determine bay dynamic processes. Federal agencies participating with NASA on the EREP project are the Departments of Agriculture, Commerce, Interior, the Environmental Protection Agency and the Corps of Engineers. All EREP photography is available to the public through the Department of Interior's Earth Resources Observations Systems Data Center, Sioux Falls, South Dakota. 57198 Photo credit: NASA

SL3-88-053 (July-September 1973) --- A near vertical view of the Tennessee-Virginia-Kentucky border area is seen in this Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The clock is in the most southerly corner of the picture. Interstate 81 under construction extends northeast-southwest across the bottom portion of the photograph. The larger urban area nearest the center of the picture is Kingsport, Tennessee. On the southern side of I-80 and east of Kingsport is the city of Bristol, Tennessee-Virginia. Johnson City, Tennessee is the urban area near the edge of the picture southeast of Kingsport. The Holston River, a tributary of the Tennessee River, meanders through the Kingsport area. The characteristic ridge and valley features in the Cumberland Plateau of Kentucky, Tennessee and Virginia are clearly visible. Forests (dark green) occur on the ridges and clearly outline the folded and faulted rock formations. The valleys (light) were formed in the softer rocks as a result of erosion. Agricultural areas are indicated by the characteristic rectangular patterns. Coal production is an important industry of this area; and it is mined by surface open pit operations. The irregular light areas in the Kentucky-Virginia border area are the strip mines which follow the contour of the land. Reclamation of the strip mine areas is aided through accurate knowledge of the mine and drainage systems. Dr. Ronald Brooks of the Wolf Research and Development Corporation can use this photograph in study of strip mine areas in the east central U.S. Federal agencies participating with NASA on the EREP project are the Departments of Agriculture, Commerce, Interior, the Environmental Protection Agency and the Corps of Engineers.

SL3-88-004 (July-September 1973) --- A vertical view of the Salinas River Valley area south of Monterey Bay, California area is seen in this Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The valley is an irrigated agricultural area, and is indicated by the dark-green and light-gray rectangular patterns in the centre of the picture. The city of Salinas is barely visible under the cloud cover at the top (north) end of the valley. The dark mass on the left (west) side of the valley is the Santa Lucia mountain range. The Big Sur area is on the left and partly covered by clouds. The Diablo Range forms the dark mass in the lower right (southeast) corner of the photograph. The town of Hollister is the gray area in the dark-green rectangular farm tracts which occupy the floor of the San Benito Valley in the upper right (northeast) corner of the photograph. The Salinas River flows northwestward toward Monterey Bay. The towns of Soledad, Greenfield and King City appear as gray areas along U.S. 101 in the Salinas Valley. The geology of the area is complex, and has been racked by several earthquakes resulting from movement along the San Andreas and subsidiary faults. Here, the surface expression of the San Andreas Fault can be traced from a point just west of Hollister at the contrast of dark brown and tan to a point about one inch left of the lower right (southeast) corner of the picture. Subsidiary faults are indicated by the curving trend of the rocks along the right side. The photograph will provide detailed information on land use patterns (Dr. R. Colwell, University of California, Berkeley) and fault tectonics (Dr. P. Merifield, Earth Science Res., Inc. and Dr. M. Abdel-Gawad, Rockwell International).

ISS026-E-025373 (10 Feb. 2011) --- Agricultural fields near Perdizes, Minas Gerais, Brazil are featured in this image photographed by an Expedition 26 crew member on the International Space Station. This detailed photograph illustrates diverse agricultural landscape patterns in the western part of the Brazilian State of Minas Gerais. Perhaps most widely known for its mineral wealth, Minas Gerais is also a large agricultural producer in Brazil. The fields in the image are located to the southwest of the city of Perdizes, which means “partridges” in Portuguese. A mix of regularly-gridded polygonal fields, and circular center-pivot fields, marks the human land use of the region. Small tributary streams (and their adjacent floodplains) of the Araguari River extend like fingers throughout the agricultural landscape. The visual diversity of field forms is matched by the variety of crops produced here: sunflowers, wheat, potatoes, coffee, rice, soybeans, and corn are among the agricultural products of the region. While the Northern Hemisphere is still in the grip of winter, crops are growing in the Southern Hemisphere as indicated by the many green fields in the image. Fallow fields—fields not in active agricultural use—display the violet, reddish to light tan soils common to this part of Brazil. The darker soils are often rich in iron and aluminum oxides, and are typical of highly weathered soil material that forms in hot, humid climates.

The Central Valley, CA is one of the most productive agricultural regions in the United States and the world. As California is in a continuing drought, it is important to monitor agricultural plant life to ensure maximized productivity. ECOSTRESS has the ability to monitor Evapotranspiration over agricultural fields. This Evapotranspiration image on the right was captured on June 09, 2022 at 06:12 PM PDT. The image on the left was captured by ECOSTRESS on June 15, 2022 at 08:27 AM PDT. Blue indicates high water use while brown indicates dry conditions. ECOSTRESS is a thermal instrument on the International Space Station that measures the temperature of the ground, which is hotter than the air temperature during the day.

ISS030-E-019144 (29 Dec. 2011) --- Agricultural patterns in Quebec, Canada are featured in this image photographed by an Expedition 30 crew member on the International Space Station. The region shown in the image, known as the Chaudiere-Appalaches, is located midway between Quebec City (the provincial capital) and the international border with the United States (specifically, the State of Maine). Agriculture is a significant component of Quebec’s industries, with over 50 per cent of the food produced or processed consumed within the province as of 2008 (source: Agriculture and Agri-Food Canada). The tapestry-like pattern is due to the fact that the agricultural fields in the region are closely tied to access roads, with rectangular fields extending outwards perpendicular to the roadways. A similar pattern—embedded within a different social, historical, and economic context—can be seen in the Rondonia region of western Brazil. Snow cover highlights the rectangular fields interspersed with dark green forested patches. The urban area of Saint Georges (left) is visible as a light gray region along the Chaudiere River. The Parc national de Frontenac borders parts of Lac (lake) St.-Francois at upper center, providing an area for outdoor recreation within the intensive agricultural landscape.

SL3-84-202 (July-September 1973) --- A vertical view of the Montevideo, Uruguay area of South America is seen in this Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The large body of water is Rio de la Plata which flows into the South Atlantic Ocean at the bottom of the picture. The red plum in the Rio de la Plata is probably sediment moving seaward. The Santa Lucia River enters the Rio de la Plata west of Montevideo and is the major drainage for the region. Note the small Isla del Tigre at the mouth of the Santa Lucia. The white beach and sand dune areas are plainly visible along the coast. A major airport can be seen immediately east of downtown Montevideo. Major thoroughfares and residential areas, such as the bright one in the suburbs, are clearly visible, also. Farm tracts in green and grey rectangular patterns indicate agricultural regions.

STS-56 Earth observation of the northeastern Nile Delta was photographed from the Earth-orbiting Discovery, Orbiter Vehicle (OV) 103. The branch of the Nile featured in the frame is Daimietta. The Suez Canal marks the boundary of the Nile Delta agriculture and the Sinai Desert to the right. Lake Masada, the dark waterlogged area to the west (left) of Port Said is becoming more saline as the Aswan Dam has reduced sediment downstream. This sediment reduction, according to NASA scientists studying the STS-56 photography, has resulted in increased coastal erosion and the intrusion of a salt-water lens to the ground water, particularly in the northeastern portions of the delta. Center pivot irrigation fields are located along either side of the Ramses Canal, which connects the Daimietta Nile with Great Bitter Lake. This canal has been re-dug three or four times in the past 3,000 years. Historians note that the canal's most famous use was as the departure point of the fleet of Pharaoh Necho. The fleet circumnavigated Africa clockwise from the head of the Red Sea to the Mediterranean coast of the Nile (probably the Rosetta Nile) in a three-year voyage circa 660 BC.

ISS030-E-090918 (21 Feb. 2012) --- Agricultural fields in the Wadi As-Sirhan Basin in Saudi Arabia are featured in this image photographed by an Expedition 30 crew member on the International Space Station. Northern Saudi Arabia hosts some of the most extensive sand and gravel deserts in the world, but modern agricultural technology has changed the face of some of them. This photograph presents the almost surreal image of abundant green fields in the midst of a barren desert ? specifically the Wadi As-Sirhan Basin of northwestern Saudi Arabia. As recently as 1986 there was little to no agricultural activity in the area, but over the subsequent 26 years agricultural fields have been steadily developed, largely as a result of investment of oil industry revenues by the Saudi government. The fields use water pumped from subsurface aquifers and is distributed in rotation about a center point within a circular field ? a technique known as center-pivot agriculture. This technique affords certain benefits relative to more traditional surface irrigation such as better control of water use and application of fertilizers. The use of this so-called ?precision agriculture? is particularly important in regions subject to high evaporative water loss; by better controlling the amount and timing of water application, evaporative losses can be minimized. Crops grown in the area include fruits, vegetables, and wheat. For a sense of scale, agricultural fields in active use (dark green) and fallow (brown to tan), are approximately one kilometer in diameter. While much of the Wadi As-Sirhan Basin shown here is sandy (light tan to brown surfaces) and relatively flat, low hills and rocky outcrops (dark gray) of underlying sedimentary rocks are visible at left and right.

STS060-93-081 (3-11 Feb 1994)--- The Imperial Valley was documented using three films - color visible (seen here), the American infrared film (Kodak Aerochrome 2443), and the Russian panchromatic infrared film (SN-10). Results of this test still await detailed science analysis. However it does appear that good data was acquired of the region, and this data will be complemented by photography acquired by the Mir cosmonauts. In this frame, the U.S.-Mexico border goes from the upper left to the middle right. It is discernible as a vegetation line between Calexico, California and Mexicali, Mexico. The darker vegetation north of that line is due to different agricultural practices, heavier uses of fertilizers and pesticides, and lined (tiled) agricultural fields allowing subterraneean runoff of saline irrigation runoff. South of the line, the more polluted water draining out of the U.S. agricultural areas into the Mexican area has resulted in higher soil salinities and a consequent reduction in agricultural productivity. At the center of the frame, a large settling and desalinization plant has been built to attempt to purify, to some degree, the polluted irrigation waters draining south out of California. The All-American Canal, which brings in water from the Colorado River (off the frame, to the right), is located in the middle right hand portion of the frame. To the upper left is the normally dry Laguna Salada.

STS083-747-033 (4-8 April 1997) --- Center Pivot Irrigation, in Saudi Arabia. This irrigation project in Saudi Arabia is typical of many isolated irrigation projects scattered throughout the arid and hyper-arid regions of the Earth. Fossil water is mined from depths as great as 3,000 feet, pumped to the surface, and distributed via large center pivot irrigation feeds. The circles of green irrigated vegetation may comprise a variety of agricultural commodities from alfalfa to wheat. Diameters of the normally circular fields range from a few hundred meters to as much as 2 miles. The projects often trace out a narrow, sinuous, and seemingly random path. Actually, engineers generally seek ancient river channels now buried by the sand seas. The fossil waters mined in these projects accumulated during periods of wetter climate in the Pleistocene glacial epochs, between 10,000 to 2 million years ago, and are not being replenished under current climatic conditions. The projects, therefore, will have limited production as the reservoirs are drained. Water, of course, is the key to agriculture in Saudi Arabia. The Kingdom has implemented a multifaceted program to provide the vast supplies of water necessary to achieve the spectacular growth of the agricultural sector. A network of dams has been built to trap and utilize precious seasonal floods. Vast underground water reservoirs have been tapped through deep wells. Desalination plants have been built to produce fresh water from the sea for urban and industrial use, thereby freeing other sources for agriculture. Facilities have also been put into place to treat urban and industrial run-off for agricultural irrigation. These efforts collectively have helped transform vast tracts of the desert into fertile farmland. Land under cultivation has grown from under 400,000 acres in 1976 to more than 8 million acres in 1993.

STS111-E-5224 (12 June 2002) --- Southern California’s Salton Sea is routinely a prominent visual for astronauts passing overhead on the shuttle or International Space Station (ISS). This large lake, photographed from the station while docked to the Space Shuttle Endeavour by one of the STS-111 crew members, supports the rich agricultural fields of the Imperial, Coachella and Mexicali Valleys in the California and Mexico desert. According to geologists, the Salton Sea formed by accident in 1905 when an irrigation canal ruptured, allowing the Colorado River to flood the Salton Basin. Today the Sea performs an important function as the sink for agricultural runoff. Water levels are maintained by the runoff from the surrounding agricultural valleys. The Salton Sea salinity is high -- nearly 1/4 saltier than ocean water --but it remains an important stopover point for migratory water birds, including several endangered species. Scientists also noted that the region experiences several environmental problems. The recent increased demands for the limited Colorado River water, the scientists point out, threatens the amount of water allowed to flow into the Salton Sea, and increased salinity with decreased water levels could trigger several regional environmental crises. The agricultural flow into the Sea includes nutrients and agricultural by-products, increasing the productivity and likelihood of algae blooms. This image shows either a bloom, or suspended sediment (usually highly organic) in the water that has been stirred up by winds.

The border between Belize and Guatemala illustrates striking differences in land use practices. In a study of deforestation published in 2016, Chicas and co-authors found that in their study area between 1991 and 2014, on the Guatemalan side of the border forested land declined 32%; in Belize, forested area declined 11%. In part of their study area shown in this image, the difference is more dramatic: near-pristine forest in Belize on the right, and agricultural fields in Guatemala on the left. The image was acquired May 10, 2016, covers an area of 27 by 41 km, and is located at 16.7 degrees north, 89.2 degrees west. https://photojournal.jpl.nasa.gov/catalog/PIA21826
