The search for solutions to the pollution caused by mercury used in artisanal gold mining reveals how difficult it is to deal with a semi-clandestine activity widespread in many developing countries, often generating an informal economy. Mercury causes death and keeps more than one million people worldwide chronically and silently ill. Developing global ethics for the gold market is essential to end dumping and provide justice for miners.

Millions of households around the world need water from tanker trucks to live. Droughts, overexploitation, pollution, and lack of investment in infrastructure make this population grow by the day. It is an essential type of supply when all else fails, but it is often informal, unregulated, and without health guarantees. We must consider this so that this solution is fair for everyone and does not jeopardize the future of access to water. 

In many rural communities in El Salvador, poor governance, industrial overexploitation, and pollution leave them without access to water. The short film Private Waters, a finalist of the fifth edition of the We Art Water Film Festival, shows how the El Rodeo community has organized itself to guarantee its survival and health.

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. The short film Mami Wata, a micro-documentary finalist at the We Art Water Film Festival 5, provides a testimony of the vulnerability of millions of Cameroonians who survive in one of the most water-deficient African countries.

Success stories in the fight for access to basic sanitation are a source of lessons to attain the SDG 6. The webinar “Valuing toilets beyond visible” showcased three experiences that provide valuable knowledge on the complex relationship between defecation and sanitation: the fight against open defecation, the use of feces and the healthiness of slums.

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. In the short film Los Conductores del Agua - The Drivers of Water, a micro-documentary finalist at the We Art Water Film Festival 5, the so-called “piperos”, the water carriers, bear witness to this problem in the Mexican city of Morelia.

Migration due to poverty, violence and neglect has led to the overcrowding of hundreds of thousands of people within a few kilometers of the center of Nairobi, Kenya’s capital. The causes of the creation of slums follow a universal pattern that show us where to find the shortcomings of the universal justice we wish to create. 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? Will they guarantee universal access to water? Will they create inequalities in decision-making to face the climate crisis? 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.
