Colonies in Space: Chapter 9 – Up on the FarmVIDEO ON THE TOPIC: Building A Lunar Greenhouse - Space Documentary
Agriculture is one of the oldest and most pervasive human impacts on the planet. Estimates of the land surface affected worldwide range up to 50 percent. But while driving through the seemingly endless monotony of wheat fields in Kansas may give you some insight into the magnitude of the change to the landscape, it doesn't compare to the view from above.
When seen from space, those same boring wheat fields are transformed into a strange and even beautiful pattern. Some of the most arresting agricultural landscapes occur in the Midwestern United States in areas that rely on center-pivot irrigation shown at right. The area pictured above near Garden City, Kansas, is being farmed to the point of resembling abstract art or a Magic Eye illusion.
Groundwater from the Ogallala Aquifer is used to grow corn, wheat and sorghum in the region. The red areas actually represent the greenest vegetation. Bare soil or dead vegetation ranges from white to green or brown. Bright greens are healthy, leafy crops such as corn; sorghum would be less mature at this time of year and probably a bit paler; wheat is ready for harvest and appears a bright gold; brown fields have been recently harvested.
The circles are perfectly round and measure a mile or a half mile in diameter. In this gallery, we've collected some of the most interesting views of crops from space, including rice paddies in Thailand, cotton fields in Kazakhstan and alfalfa growing in the middle of the Libyan desert.
Bolivia The star-shaped patterns pictured above are radial soybean fields that are part of a planned settlement east of Santa Cruz de la Sierra in Bolivia. The stars radiate from small towns shown at right three miles apart and are separated from neighboring stars by a small stretch of the dry tropical forest that used to cover the area.
The image above was taken Aug. The area has been rapidly deforested to accommodate people that have been resettled from the Altiplano, the high planes of the Andes. Each small community has a school, a church, a bar and a soccer field. The deforestation of the Amazon Basin in Bolivia can also be seen in the false color image below, taken by the Landsat 7 satellite on Aug. Long paths are the result of logging and large blocks have been cleared for herds to graze. Green, healthy vegetation shows up as red in this image.
Images: 1 NASA. Sudan This interesting arrangement of rectangular fields is south of Khartoum. The crops are fed by thousands of miles of canals and irrigation ditches running from the Blue Nile. The irrigation project was started by the British during colonial times. The area pictured above is a closer look at one piece of the image below. Image: NASA. Brazil Central pivot fields are interspersed with regular grid fields and small streams in this true-color image above of Brazil south of the city of Perdizes, taken by astronauts on the International Space Station on Feb.
The crops include sunflowers, wheat, potatoes, coffee, rice, soybeans and corn. The reddish and tan areas are fallow fields. Below is an image of enormous fields in the woodland-savanna region known as the Cerrado in southern Brazil, taken Apr. Images: NASA. Libya The lonely green circles in this image are center-pivot fields 0. Virtually no area of Libya receives enough rainwater to grow crops, and the fields here are irrigated with water from an underground aquifer.
The image was made by astronauts aboard the International Space Station on Oct. The Netherlands The southernmost coastal province of The Netherlands, known as Zeeland meaning Sea Land , is made up of islands linked by dikes and seawalls that protect the vulnerable agricultural and urban areas.
Rivers and estuaries have been walled off from the North Sea to become enclosed lakes. Kazakhstan The floodplain of the Syr Darya river in Kazakhstan is an important cotton-growing region for central Asia. In this image, taken by astronauts aboard the International Space Station on Sep. In the upper left, an older stretch of floodplain is checkered with darker cotton fields.
The crops are watered from canals leading directly from the river and from a reservoir upstream. Thailand Outside of Bangkok, the landscape is dominated by stripes of narrow rice paddies fed by canals. In this simulated-true-color image, taken Sept. California The Sacramento River Delta is the main drainage for the entire state of California, funneling rain and snowmelt from the Sierra Nevada mountains toward the San Francisco Bay.
This inverted delta, where the channeling and river braiding occurs before the river reaches its outlet, has created a fertile agricultural area.
Water is pumped through canals to irrigate the fields and serve many cities in the Central Valley. The state depends on the food grown here, but pumping so much water for crops has threatened fish populations, such as the delta smelt, and long-fought legal battles continue over water rights.
This image, taken by the Landsat-7 satellite, shows the confluence of the Sacramento top and San Joaquin center Rivers and the city of Antioch bottom left. Minnesota Northwestern Minnesota is dominated by rectangular agricultural fields growing crops such as wheat, soybeans, corn, hay, alfalfa, flax, barley, sugar beets and potatoes.
In the true-color image above, taken Sept. Harvested fields are brown and tan. Farmers in the area use false-color satellite images, like the infrared view of the same area below, to assess the health of their fields and keep an eye on flooding, hail-damage, pesticides and weeds.
Egypt The Nile river supports a striking swath of agriculture in Egypt. This image was taken by the Landsat-7 satellite on Oct. The line between the two is sharp because the fertile stretch is contained within the walls of the river valley, which can't be seen because the shot was made from directly above the river.
Light green patches are crops, dark green is forest, grey is bare soil or urban areas, and the bright blue and white striped area is the mine.
The mines in the area are worked by the Bagger , the largest machine in the world. The bucket-wheel excavator is twice as long as a soccer field and as tall as a story building It digs up 30 million tons of lignite per year.

B rent Bierbaum climbs into the ditch running alongside one of his corn fields and dips a nitrate testing strip into the water. He checks the strip: the reading is somewhere between 10 and 20 parts per million. It confirms the water running off this field contains nitrates at levels that would be unsafe, and illegal, in drinking water. Brent, whose family have been farming in this part of south-west Iowa for five generations, never used to worry about the runoff from his fields. Things changed when his local town, Griswold, started having problems with their drinking water.
Maximize Your Space: The Case For Micro-farming
One of 46 leaflets produced as part of the European AGFORWARD project, this covers how to make the most of space in an agroforestry cropping system, particularly focusing on managing the understorey, which can often be underutilised and lead to problems with weed control. It can be put to productive use through planting crops that are adapted to shady conditions, and can be a resource for biodiversity; providing a habitat for beneficial insects and a food resource for crop pollinators. The leaflet looks at different understorey crop options, focusing particularly on trials carried out by Iain Tolhurst in his horticultural agroforestry system. It also looks at advantages of growing additional crops in the tree understorey, information on yields, establishment and management, and biodiversity and pest control impacts. You are here Home.
Supersmart satellites reveal crops and fields like never before
A new facility to assist advances in crop science is taking shape in the Norfolk countryside. The field experimental station at Church Farm, Bawburgh, will allow scientists at the John Innes Centre to carry out ground-breaking research in crop improvements. Bringing together lab and field research in one location will further research in understanding how genes control plant growth in the field. The aim is to create tools for plant breeders to produce new varieties that are more reliable, nutritious and resilient to pests and diseases.

The Farms of the Future Were Built for Outer Space. Will They Work on Earth?
Organic agriculture provides healthy food and protects the environment by practising methods that avoid the widespread dissemination of chemicals. ESA is now helping to develop the use of satellite images for certifying crops as organic. Products can be labelled 'organic' only if they are produced according to a set of standards, undergo an evaluation and pass a yearly inspection. Since organic and conventional crops are treated differently, their characteristics are also different.
These revolutionary vertical farming innovations can soon replace the traditional agriculture techniques. Many have wondered for years if vertical farming is really the answer to the shortage of food in the world. However strange the concept of vertical farming might seem to many startups, it is an ingenious method to produce food in environments where arable land is unavailable or rare at the most. This method is especially handy for challenging environments such as deserts, mountainside towns, and cities where many diverse types of vegetables and fruits are grown using precision agriculture methods and skyscraper-like designs. This innovation in the field of agriculture with sustainability as its motto is making more and more heads turn today with its eco-friendly methods and making the possibility of farming real in difficult environs. Let us check out the top 13 vertical farming innovations that could end up in your plate in the near future! Hydroponics is a predominant system of growing that is used in vertical farming, and it is slowly but steadily, gaining importance. It involves around the growth of plants in solutions of nutrients that are essentially free of soil. In this vertical farming innovation, the roots of the plants are submerged in a solution of nutrients. This is frequently circulated and monitored in order to ensure that there is the maintenance of the correct chemical composition in the nutrient solution.
Crop Tops: Strange Agricultural Landscapes Seen From Space
The most important effect of temperature is that it affects the rate at which plants develop through their stages p 8 and produce their leaves, tillers and other components. Everything goes progressively faster as temperature rises between a base and an optimum temperature p 81 , and similarly development slows at lower temperatures. Calculating the size of these effects is discussed later p Good farm management can do more to counter the negative effects of high temperature than it can with low temperature and particularly frosts. Development slows at lower temperature. But when temperatures are low enough for frosts, severe damage is done to young tissues. The consequences to yield of two or more successive frosts from spike emergence Z5. Official Stephenson Screen temperatures p 90 of 1. A single night frost during this period may not be overwhelming because only the new tissue that has been exposed to the air during the last few days is killed. This is seen as banding of dead and live spikelets on the spikes.

In an old carpet factory on the outskirts of the Belgian city of Kortrijk, an agricultural upheaval is being plotted: growing crops indoors, not out on a farm, stacked layer after layer under candy-coloured lights in an area the size of a studio flat. In its case, a large frame is designed to hold conveyor belt-shunted trays of young plants under gently glowing blue and red LEDs in this former carpet factory. But their system, largely automated, is still a work in progress. When I visit, a software update, scheduled at short notice, means that none of the machinery is working.
Farm building , any of the structures used in farming operations, which may include buildings to house families and workers, as well as livestock, machinery, and crops. The basic unit of commercial agricultural operation, throughout history and worldwide, is the farm. Because farming systems differ widely, there are important variations in the nature and arrangements of farm facilities.
