Water4Future Students Hackahon

The UNESCO ICIREWARD International Centre has developed Water4Future (W4F). This programme is divided into three formats: junior, high school and students.

The student version is an international competition: the Water4Future Students Hackathon. In teams of 5 to 7, they have 48 hours to set up an innovative, technical and social project addressing a water-related issue. Each year highlights a new theme.

The aim is to create a team project, encourage an entrepreneurialspirit, and come up with new tools, technologies or innovative services to protect our environment and improve people's everyday lives.

VEOLIA

Veolia manages every stage of the water cycle and addresses the wide range of challenges faced by local authorities and industry: resource management; the production and distribution of drinking water and industrial process water; the collection, treatment and recovery of wastewater from all sources and of by-products resulting from its treatment (organic matter, salts, metals, complex molecules and energy); customer relationship management, and the design and construction of treatment facilities and networks.

This extensive expertise enables Veolia to support its clients in implementing integrated and sustainable water resource management.

The Southern Region covers the departments of Aude, Aveyron, Gard, Hérault, Lozère and Pyrénées-Orientales. The operational organisation is thus divided into five entities known as ‘Territories’, located in: Narbonne, Rodez, Alès, Montpellier and Perpignan. These entities ensure, within their respective areas, the sustainable management of all the services entrusted to them.

Rivers are essential to life. The future of all forms of life and of our societies depends on their health. Yet they are particularly vulnerable and under threat from the effects of climate change and human activities.

This is why the NGO Initiatives pour l’Avenir des Grands Fleuves (IAGF) was founded in 2015 by Erik Orsenna and the Compagnie Nationale du Rhône, with the aim of raising awareness, mobilising action on the challenges and future of rivers, and encouraging more sustainable practices.  It is urgent that we act by promoting rivers as sources of solutions, life, bonds and development. This is why IAGF shares a multidisciplinary, systemic and balanced vision of the challenges and uses of rivers.

As a collective of multidisciplinary experts, IAGF provides a space for international dialogue and the exchange of knowledge, open to stakeholders from rivers around the world.

We focus on three areas of action:

Dialogue and expertise, Awareness-raising and advocacy, Promoting solutions.

AGF is delighted to be partnering with the UNESCO ICIREWARD International Centre and to contribute to this latest edition of the Water4Future Students Hackathon. This commitment lies at the heart of our mission: to educate, inspire and support a new generation capable of devising sustainable solutions for water and rivers. This hackathon stands out for its collaborative spirit and educational innovation, which enable participants to fundamentally rethink their relationship with water as future stewards of the planet. “Erik Orsenna, President of IAGF”
