"The Land Institute has worked for over 20 years on the problem of agriculture. Our purpose is to develop an agricultural system with the ecological stability of the prairie and a grain yield comparable to that from annual crops. We have researched, published in refereed scientific journals, given hundreds of public presentations here and abroad, and hosted countless intellectuals and scientists. Our work is frequently cited, most recently in Science and Nature, the most prestigious scientific journals. We are now assembling a team of advisors which includes members of the National Academy of Sciences. These scientists understand our work and stand ready to endorse the feasibility of what we have come to call Natural Systems Agriculture."
