The Nomad Garden is an ode to the impossible. A young Sahrawi refugee shows how he grows organic vegetables and herbs in one of the most inhospitable places on Earth, overcoming challenges like the lack of water, extreme temperatures and a barren soil.

Taleb, who came to a refugee camp at the age of five in 1975 and returned there after his studies abroad, tells of his life as a displaced person, his gratitude for the reception and support in Algeria, and his hope that the Sahrawis may one day return to their homeland. For Taleb, this hope drives him to actively prepare for better times: as a graduate in agricultural sciences, he conceived a successful small-scale closed-loop economy in a desert under the most difficult conditions, producing enough food for self-sufficiency.

Sahrawi artist and visual poet Mohamed Sleiman Labat follows the story of the emerging phenomenon of small scale family gardens in his local community in the Hamada Desert. The film features the story of four families in Samara Camp with small scale gardens, their practices and the knowledge they develop as part of their practices in the garden. The camps are located in a very harsh environment with extreme climate conditions, and the Sahrawi are still dependent on international food aid.

Thule, Greenland, also called Qaanaaqis, one of the northernmost towns in the world. As the climate warms and the ice caps begin to melt, the gentle balance of life for the people of this community is in jeopardy. On the other side of the globe, the melting ice caps are raising sea levels around the Polynesian island nation of Tuvalu, threatening to wipe the island right off the map. Though a world apart, these two communities are intricately connected as environmental balance begins to tip and traditional ways of life are threatened. 'ThuleTuvalu' is a stunning documentary addressing the high price of a hundred years of development and how two very different communities are now bound together in facing an uncertain future.
