| Sumario: | A dynamic systems model is presented, showing the relationship and interdependence between climate—defined as a quasi-stable natural resource—and all other natural and artificial resources.
This model aims to highlight how the use of such resources feeds back into climate as an ultimate determinant for humanity, a fact now widely recognized worldwide. Under the same framework of dependence, the potential production and historical evolution of forestry, agriculture, and livestock production in Latin America were studied in a general way, in relation to population growth.
Based on these antecedents, and notwithstanding the lack of more systematic experiences, several case studies were used to illustrate how the impact of different land uses—which may degrade or improve the environment in Latin America—can be understood in terms of their effects on climate.
The direction of change in local and regional climates was analyzed by examining alterations to the main biomes of tropical humid climates. These cases included the development of agriculture and the introduction of pasturelands in mountainous and highland rainforests; the flooding of várzeas and coastal mangroves; improvements to monsoonic savannas through deferred flooding and irrigation; and the amelioration of semiarid and arid lands through irrigation. Conversely, cases were considered in which desertification was exacerbated by soil mismanagement and overgrazing in semiarid and arid rangelands. |
