The Greening of Art describes the shifts in position between art and nature which took place during the past fifty years, to set out re-establishing a new relationship between art and the landscape-environment, and attempt in various ways to re-connect art with nature. From the 1960s onward, when artists went outdoors to explore the environment as extended space of the self, via land reclamation projects and collaborations with landscape architects in redesigning whole parks to the present day, with its recent development of urban gardening projects.

Marga Bijvoet, art historian, has worked amongst others at the Long Beach Museum of Art, the Rijksakademie van Beeldende Kunsten and Time Based Arts Amsterdam, and published on art and technology in the United States in the 1960es and 70es (Art as Investigation).
