Abstract
The ecological theory has been developing for many years in the same conceptual and methodological framework as the general theory of Systems (Hernández, 1991). Ecosystems, as complex systems, are in many cases difficult to study, but much more when they are subjected to human interventions during many centuries. Such is the case of Agrosystems. the agricultural landscape is the expression in space and time of human effort in search for his daily nourishment. But since the landscape is a complex system of relationships, it is necessary to analyse its components so as to understand the past and their processes of development.KeywordsSoil Seed BankConservation PracticeSemiarid EnvironmentSoil Conservation PracticeEcological ThoughtThese keywords were added by machine and not by the authors.
