Planet in question wants to reverse our gaze on the idea of development: with environmental, financial and economic crises, the concept of development is now open to the main planetary themes to form today the concept of sustainable development. In our globalized world, our fate is tied to that of others and it is important today to understand what connects us. In this context, multiple initiatives are born in the South and call into question the concept of development advocated by the North. These initiatives come to life in an individual or local way and by their pragmatism, their very concrete inventiveness, they are a means of effective and appropriate battle for a better life. Planet in question wants to question and open the debate by focusing on these new and original ideas, born in a particular context all around the world, but carrying great promises for humankind. "Mokoomba: from one shore to an other" by François Ducat and Frank Dalmat: How can one be a musician when his family has nothing and needs each of its members to contribute regularly? The film offers a reflection on the impact of music in the lives of African musicians. In a country where even the ants live in poverty, to make music like a cricket is a challenge which may give some original answers. "The Elastic Forest" by Jean-Philippe Martin: In Laos, where still today one of the last primeval forests of Asia remains, deforestation has experienced in recent years a dramatic development. This because of the exponential growth of areas planted with rubber trees. "Campus Congo" by Ronnie Ramirez and Gauthier Jacob: The University of Lubumbashi is not on an equal footing with the universities in developing countries. Industrial countries always provide help but they don’t bring the real emancipation that this country needs. If the Congo does not have proper universities it will not have doctors, engineers, vets, agronomists, development. There is no future without education. "The Harvest of Hunger" by Marie-France Collard: Through the story of a wheat harvest, between sowing and harvesting, import and export, between transformation into foodstuff and consumption, the film crosses the destinies of very different farmers in the North – France and Belgium – and in the South-Bolivia, Venezuela, Columbia.
