North America: Its Rivers(1971)

Joseph Vallot, geographer, naturalist and mountaineer born in 1854 in Lodève, was a visionary man, full of humor and whose curiosity was insatiable. He had spent some forty years of his life studying the Mont Blanc massif, sacrificing a good part of his fortune to this multifaceted passion. He was notably the first to demonstrate that one could sleep, work and even do science at an altitude of over 4000 meters, at a time when ascents to the summit of Western Europe were still adventurous expeditions. This documentary tribute follows in his footsteps, via the route taken at the time, on foot from Chamonix via the Grands Mulets refuge to the summit of Mont Blanc to the Joseph Vallot observatory nestled at an altitude of 4400m, with a team of guides, journalists and scientists.

Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.

Although it crosses six countries and is over 3,500 kilometers long, the Zambezi is one of the least known rivers in the world. So it's time to take to the water and discover this mystical, ever-changing river, whose mood changes from day to day, kilometer to kilometer, and which is the very essence of life for millions of animals and people in this often drought-stricken, water-scarce region!

A panoptic film on water, energy and climate, SunGanges (SuryaGanga) is a wild and intense ride three filmmakers take across the vast Indian landscape in an attempt to connect the dots between vanishing rivers, massive energy projects and the quiet rise of renewable energy.

It shows the Neretva river from its source to the shores of the Adriatic Sea. The document also captures the original four-hundred-year-old bridge in Mostar.

The Balkans cradles Europe's last wild rivers and supports abundant wildlife and healthy, intact ecosystems. These rivers are "The Undamaged" – clean, pristine, and undammed. With over 2,700 small and large hydro power plants planned or under construction in the Balkans, corruption and greed are destroying the last free-flowing rivers of Europe. Follow the Balkan Rivers Tour, a rowdy crew of whitewater kayakers, filmers, photographers and friends who decided to stand up for the rivers, travelling from Slovenia to Albania for 36 days, kayaking 23 rivers in 6 countries to protest the dams and show the world the secret wild rivers of the Balkans. The film honours everyday people and local activists who are fighting to defend rivers and aims to spread the word of the plight of these rivers, showing a new style of nature conservation that is fun, energetic and effective.

Yaku: water; aya: essence, blood. Yakuaya is a non-verbal documentary about the descent of water and life that follows the journey of a drop of water from its birth on a glacier until its arrival at the sea. Along the way, water influences the life of a peasant, locks himself in the rhythm of a bottling factory, brings people together in the city, transforms the life of a woman, leads a river navigator, awakens hope in a desert and welcomes the innocence of two children in the sea.

A New Yorker journeys to the jungle in the Darien Gap of Panama to reconnect with an indigenous tribe he met and photographed 20 years ago. Their reunion highlights the profound power of photos and the human connection that transcends cultural barriers.

In Tacony Creek Park, home to one of Philadelphia's lesser-known watersheds, Julie Slavet and Malcolm Bundy reflect on their involvement with and love for the park, made bittersweet by the continuous and increasing amount of pollution that flows into its river. Combined wastewater and stormwater sewage outfalls have affected Philadelphia's rivers for years, but as one innovative program mitigates this for the Schuylkill and Delaware, Tacony gets left behind. Scientist Laura Toran educates the audience on green infrastructure and its potential positive impacts, while Slavet and Bundy discuss how they're still waiting—not without hope—for those impacts to reach their community.
