The climate crisis is creating severe problems in Cameroon. Desertification and floods generate thousands of displaced people every year who end up in cities unable to provide drinking water for all.

Uncontrolled urban growth destroys water around it, creating a serious supply problem. Many cities around the world need to search for water further and further away.

The short filmRaindrops, by Stephen Okoth, finalist of the We Art Water Film Festival 5, recreates a real common story in Kibera and in all marginal neighborhoods around the world.

Will algorithms and big data be able to control the 42,000 km³of usable fresh water all around the world? Will they be able to monitor its efficient use worldwide?

These are not science-fiction questions; in the smart world that is already underway, they point towards a future that is the goal of the current technological development based on big data and artificial intelligence.

In all activities carried out during this hard year, we have been faced with human suffering, but we have also found hope. Hope generated by the knowledge of being understood and helped; the one generated by the enthusiasm and generosity of the institutions we collaborate with. These have redoubled their efforts despite all difficulties and deserve our admiration and gratitude. We will continue to be there, collaborating to overcome them, because we share the conviction that solidarity is a never ending asset.

The health emergency poses new challenges to urban planning.
