The landscape, in crisis because of the abstraction process of Human and Nature relationship, requires tools able to face the distance and the loss of character and materiality of our life environments. Countries are reduced to open spaces and parks to green spaces. The opposition between full-void shapes landscapes becomming objects without meaning. The sustainable development, a new green revolution, might become a new slogan of consumer's society. The horizontal glance allows to find new methods of reading and writing to decode the environment materiality, awakening the body to tactile perception. The project as an open work permits the evolution of intentions and integrates Nature, time and mutation as elements of landscape co-generation. Observation, sites practice and awareness become the active material of the landscape project.Peer reviewe
