Agriculture Across California’s Great Central Valley, USA

USA - June 11th, 2012

California’s Central Valley is a large, flat valley that dominates the central portion of California. The valley stretches approximately 450 miles (720 km) from northwest to southeast inland and parallel to the Pacific Ocean coast.

The ‘Central Valley Grassland’ is the Nearctic temperate and subtropical grasslands, savannas, and shrublands ecoregion which was once a diverse grassland containing areas of desert grassland (at the southern end), prairie, savanna, riverside woodland, marsh, several types of seasonal vernal pool and large lakes.

However much of the Central Valley environment has been removed or altered by human activity including the introduction of exotic plants, especially grasses. It is home to California’s most productive agricultural areas.¬†The wetlands have been the target of rescue operations to restore areas nearly destroyed by agriculture

From the Salton Sea to the White Sands Dune Fields, Mexico and USA

Mexico - April 15th, 2011

The Salton Sea appears as a small, dark blue, pear-shaped  mark in near the upper left corner of this thumbnail image near the California-Mexico border, although it and the agriculture to the south of it can be viewed in great detail in the full image.

Continuing southeastward along the agricultural zones, one passes the sandy Desierto de Altar before coming to the Sea of Cortez (Gulf of California), whose northermost reaches are green due to the influx of sediments from the Colorado River.

Moving over to the upper right corner, in New Mexico, one can see the White Sands National Monument, a white sand dune field, and the Carrizozo Malpais, a large lava flow that appears as a dark brown line north of the dune field. Both are best observed in the full image.

Brazil - December 31st, 2010

This APM image shows part of the Brazilian state of Mato Grosso, meaning “Thick Woods”. Despite its name, the state actually has three different ecosystems: Cerrado, Pantanal and the Amazon Rainforest.

Open pasture vegetation covers 40% of the state. This image highlights fields and areas of agriculture, as they stand out as orange, green and grey geometrical shapes, while uncultivated lands appear bright yellow. Rivers appear as dark green ribbons.

Agriculture Around Mississippi River From Northern to Southern USA – November 8th, 2010

USA - October 14th, 2010

The image stretches through the central part of the United States of America, from the Great Lakes (the tip of Lake Michigan can be seen at the very top) to near the Gulf of Mexico.

The Mississippi River, running through the middle of the image from top to bottom, is the largest river system in North America, with a length of about 2,320 miles (3,730 km).

Much of the land in the Mississippi River Valley and around the river and its tributaries appears tan here, while the land further west and east appears green and vegetated. This tan color is probably due to the land around the river being used for agriculture.

Agriculture in the Western USA – August 2nd, 2010

Despite the arid desert stretching across most of this image of the western United States and northwestern Mexico, quite a few areas of agriculture can be observed. The most evident are those of the Great Central Valley in California, on the left hand side of the image.

Upon opening the full image, more agriculture, created by irrigation schemes, can be seen near the Salton Sea, a lake visible at the bottom center, and at the top center of the image. These fields appear mostly rounded, with varying shades of green.

Another important body of water visible here is Lake Mead, on the Colorado River. The lake is situated just to the right of the image center, and can be quickly found thanks to its three-armed shape.
