Ecology of Agricultural Systems
Sustainable Development Goals
2. To identify negative externalities and environmental impacts related to different agricultural systems.
3. To provide fundamentals of ecology upon which the agricultural systems should stand, encouraging the students to propose measures and actions compatible with the wise use of agro resources, which is the main goal of this curricular unit.
2. The second great human impact on biosphere: the invention of agriculture. Characterizing different agricultural productive process, namely in what concerns: energy flow, matter cycling and biodiversity across hierarchical levels of organization - within species, alpha, beta and gamma.
3. Ecosystems attributes versus agricultural systems attributes: complexity/simplicity; diversity/monotony; homeostasis and resilience/regulation by man. Negative externalities and environmental impacts of different agricultural productive processes: greenhouse warming, degradation of habitats and deserts spreading. The implications of agricultural systems on biotopes naturalness and sensitivity.
4. A false dilemma - to produce or to conserve: ways of overcome this apparent problem; examples.
Two written tests. Final examination.
