European farmers no longer import some of their food because they have high efficiency farms and a food surplus. Because of this, some farmland has been set aside for nonfood crops, such as timber, oil-producing seeds, sports grasses, and plants and animals from which clothes are made. This British production shares creative and innovative uses of land formerly kept only for food crops.

At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of the plants featured in thousands of time-lapse movies Spalding has created over the past five years. The goal is to figure out how to grow crops optimally.
Offers a look at what kind of information satellites provide about our world. Satellite imagery has multiple uses: showing crops and pests, monitoring weather in all its forms, following forest fires and air pollutants, and more. Imagery notes climate changes, the ozone layer, and temperature of many things--all designed to predict and protect. These sensors present unusual windows to our world.
One of the fifteen parts of the "Farm to Market" series. Consumed by both people and animals, corn and rice are two of the most important food crops in the world. Shows how they are grown and harvested. Talks about different types of corn, such as popcorn. Planting rice in flooded fields from the perspective of a person in a rice-seeding plane is overviewed. Also shows how these crops have alternative and environmentally friendly uses, such as rice straw and fuel.
Learn how organic farmers diversify their crops and control pests with natural enemies in order to farm without chemicals. Viewers also explore the economics and impacts of traditional and organic farming. Part of "The Botany of Desire" series.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, author Michael Pollan defines monocrops and how these crops have changed agriculture. Part of the Nourish Short Films Series.
Superhero Autumn Ray must stop a storm before it destroys crops and damages property. As she works to stop the storm, she also explains how storms form. She and Dr. Mother Nature also discuss the different types of clouds. Part of "The Science of Climate" series.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, farmer Nigel Walker discusses how he decides from which plants to gather seeds. Theses seeds are used to produce future crops. Part of the Nourish Short Films Series.
Argentinean agriculture has one of the world’s highest productivity rates and is known for its soybean, corn and sunflower crops. However, the industry is also a significant contributor of greenhouse gas emissions. These climatic changes could in turn affect the productivity of the agricultural sector as well as impact economic aspects of the farmers’ lives. Chapter 3 of Air: Climate Change Series.
The mid-latitude and polar regions are two of earth's three climatic zones. The mid-latitude, or temperate, regions have definite seasonal changes in temperature and length of days and nights. Polar climates have extremely cold temperatures. Covers the climatic characteristics of the five subregions of the temperate and polar zones, noting also the vegetation, animal and human life, urban centers, and food crops.
This program from the acclaimed PBS Nature series, "Forces of the Wild," focuses on how the movements of the sun and moon create powerful rhythms which influence all living things on Earth: tides rise and fall, seasons change, creatures breed or migrate, and humans plant crops and celebrate holidays. Narrated by James Earl Jones.
Just like animals and humans, plants have their own microbiomes, which help them stay healthy and provide them with nutrients. Some of these microbiomes include symbiotic fungi that can help certain plants deal with tremendous environmental stress, including heat stress. Scientists are studying how fungi like this might be used to help alleviate the impacts of climate change on food crops. Part of the "I Contain Multitudes" series.

The Center for Advanced Forestry Systems is using forestry science and collaborations among universities, industry, and the government to make commercially grown forests more productive and sustainable. With support from the National Science Foundation (NSF), research teams at Virginia Tech, North Carolina State University, and the University of Washington have teamed up through the center to study how new slow-release fertilizers could improve growth and not destroy waterways.

In the 1950's, the Soviets decide to turn the vast desert steppes of Kazakhstan and Uzbekistan into fields of cotton and wheat. They diverted some of the rivers that feed the lake to irrigate the new crops. This depleted the Aral Sea, and in 1987, the level of the water falls so low that the sea splits into two bodies of water. It splits again in 2002. In 2014, the eastern part of the Aral Sea disappears forever, which causes an ecological disaster. Part of the "Butterfly Effect" series.
A chart of exponential growth shows that some things change faster over time. Back in 1798, Thomas Malthus noticed that not everything grows this way. This caused people to worry, and they were sure it would lead to massive death, starvation, and famine. However, the Green Revolution kept this from happening, and scientists are currently working to produce enough food for the current exploding population. Part of the “It’s Okay to Be Smart” series.
Welcome to the North Carolina State University (NCSU) Phytotron, a singular facility for growing plants under various combinations of strictly controlled environmental conditions. Scientists are able to conduct all types of plant research here, from studies of disease-resistant crops to drought-proof grasses to new biofuels. The NCSU Phytotron was built in the 1960s with support from the National Science Foundation (NSF), and was used a decade later to help prevent a collapse in the U.S. corn crop from fungal disease. Now, after more than a generation of such research breakthroughs, the Phytotron has received additional support from NSF for a 21st century makeover. The renovations include a new Biosafety Level 3 (BSL-3) lab with a greenhouse that houses high security research, such as experiments with viral and bacterial pathogens.

Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko wonders why all the clouds come and cry over his village at the same time. What makes them so sad? He questions the wise old man of the village, who suggests that he wait till the end of the rainy season for the answer. Once the rains are over, Moko goes back to see the old man. The old man tells him that the answer lies in the fields and the crops. Moko sees that the rain has allowed so many things to grow, and that the village has all the food it needs. So he realizes that the clouds are not sad when it rains, but rather that they give all their water to fertilize the soil.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko wants to know what lies beyond the forest and decides to go find out. Totemie comes along and after a long walk they find a mountain village. Moko, who hasn't seen the ocean in a long time, is dreaming of seeing it again, but realizes that it will be awhile before they cross this mountain and see the sea. But then, they see boats and barges. Why would there be boats on a mountain? An old man comes to them and tells them that if it is the ocean one seeks, sometimes it can be found even on a mountain. Curious, Moko and Totemie walk on into the forest and discover what can only be an ocean atop the mountain, only here they don't say ocean or sea, but rather they call it a lake. Moko believes that this lake is here in order to console the people who cannot live beside the ocean.
