    Example text

    This sidesteps the possibility that it is causing serious negative consequences right now, in the present. Conversely, arguing for the desirability of a system or practice because it is “sustainable” is really to say that its major benefit would be its durability over time—that we could expect it to still exist at some time in the future. This by itself does not ensure that the system or practice mitigates or reverses harms to people or natural systems. And underlying these drawbacks is a very real practical problem with the concept of sustainability: because sustainability per se can never be demonstrated in the present, its proof always remains in the future, out of reach.

    Although we have accumulated a great deal of knowledge about the ecological relationships underlying sustainable food production, that knowledge has seen relatively little application, and industrial agriculture has meanwhile strengthened its dominance of the world food system. Transforming agriculture in a fundamental way—putting it on a sustainable path—is going to be a tremendous challenge. A basic assumption of this textbook is that agroecologists can hope to meet this challenge only if we approach it on three different fronts simultaneously.

    Role of Agroecology Many scientists, researchers, and educators in the field of agroecology, and their colleagues in disciplines like agronomy, have long believed that their role is to come up with agricultural methods and systems that are more sustainable, more environmentally friendly, less input dependent, and less technology intensive than those of industrial agriculture. The assumption is that these methods and systems will then be adopted because they are superior when judged by any of various sets of criteria.
