Terres nourricières

S1 E9
·
2016

At the beginning of the 21st century, agriculture remains the most important activity for humanity: it employs more than 40% of the world's active population. And the challenge is huge: to feed the 9 billion human beings who will soon populate the world, while its resources are depleting and global warming threatens our environment. But before reaching a turning point, solutions exist. Their development mobilizes agronomists and farmers to hope to make the Earth a nourishing land. From ancient Egypt to nowadays, this documentary deals with the various techniques, know-how and technologies that make it possible to reach this objective.

E4 : À la conquête de l'autre rive

51min51s
Reaching the other side of the river, crossing the bay, a curiosity, then an obligation that pushed Man, from the first times of his history, to develop construction techniques to cross these obstacles. From the first liana bridges, through the Roman aqueducts to the Millau viaduct which spans the Tarn valley at a height of 270 m, man…

E6 : Les maîtres du rail

52min2s
Crossing landscapes at more than 300 km/h is obvious in the 21st century. However, very high speed is a feat and the result of two centuries of an incredible technological epic that has changed the history of mankind. Matthieu Barreau is an engineer and teacher in mechanical engineering at the IUT of Cachan. He will follow in the…

E7 : Les conquérants des sommets

52min31s
Until the end of the 17th century, mountains were simply considered as geographical obstacles, barren, useless and above all frightening lands. Scientists were the first to be seized by the desire to explore them. Among their first objectives were the prevention of avalanches, as well as the accessibility of the most remote areas…

E8 : Les conquérants des pôles

52min37s
For many years, the conquest of the poles has been a real competition: many have tried, many have failed, sometimes so close to the goal. Today, the challenge is no longer to reach the Arctic and Antarctic, but rather to study these two regions and find the real reasons for the melting ice. Witness a century of conquest and follow in…

Friend, but also enemy, fire is essential to life and human activity. From the Neolithic era to the conquest of space, the mastery of fire has allowed humanity to develop and ensure its evolution on the planet. How, over the millennia, has Man learned to recreate and master it, what sciences has he discovered, what techniques has he…
