Since its founding in 1996, one of the objectives of the EHZ festival has been to support associations and social movements that share common values. They stress that they do so in different ways: "Publicizing the struggles of Euskal Herria, practicing a society based on equality, Basque culture, ecology, the defense of precarious social classes, or directly supporting associations".

And so, another year, part of the festival's benefits have been donated to an association: To Lurzaindia, "the occupation of the Berros de Arbona, the struggle for the land of the Marienia de Cambo to continue to be cultivated and every day for the work in the shade performed by different crops and militants".

The members of the RSI emphasize that through the work of Lurzaindia it has been allowed to protect certain crops from land speculation, redistributing them to peasants. And beyond the actions of Lurzaindia, they wanted to highlight a value they defend: the land belongs to all. "Nowadays, in Euskal Herria and abroad, cultivation is sold according to the capitalist market logic, while the work of Lurzaindia follows a reverse logic, cultivation emerges from the logic of supply and demand and is managed collectively so that the soil that grows us does not lose its function, putting general interests before private interests".
