Homo sapiens), the activity of agriculture takes place within the confines of the ecological laws that apply everywhere and the activity of humans within that system is part of the system itself. Agroecology is an alternative syndrome, itself eclectic and diverse, but focusing on some simple ideas: farming with nature rather than trying to dominate it, conserving biodiversity and ecosystem functions, promoting such human values as justice and equality, respecting not only the laws of nature but also the traditions of the human societies and cultures involved in that nature.
39 With help from USAID, coffee intensification (also called “coffee technification”) became one of the cornerstones of their recovery plan. Incentives were established to eliminate shade trees and to plant coffee varieties, like caturra and catuai, that were higher yielding and could better tolerate being grown in the open. 40 In 1988, when we were teaching a field course to a group of Latin American students, the coffee technification program had reached its zenith in Costa Rica. Having become accustomed to the forest-like traditional plantations that were so common in Costa Rica, we started wondering how much diversity was being lost with the elimination of the shade trees.
Unfortunately, it is a question too infrequently pursued in agroecology, but fundamental for the sustainable management of agroecosystems. There is an enormous literature on this classical ecological question (see any textbook in ecology). Although debates on the details continue to rage, elementary theory in ecology provides us with a very simple dichotomy of mechanisms. , if birds nest in trees, the number of trees in a system at least partially determines how many birds can survive). This is the first part of the dichotomy, frequently referred to as the “carrying capacity” of the environment for that particular population.
