The Land Institute is working to develop perennial grains, pulses, and oilseed-bearing plants to be grown in ecologically intensified, diverse crop mixtures under its Natural Systems Agriculture program.

In tandem with these sustainable agriculture efforts, the Ecosphere Studies program seeks to change the way people think about the world and their place in it, through educational and cultural projects with a perennial perspective.

Now in its fourth decade, The Land Institute is beginning to demonstrate progress in developing the perennial crops called for in the Natural Systems Agriculture model.
