The students are expected:
-To recognize, in a historical perspective, the influence of agricultural practices in the shaping of mountain landscapes.
-To recognize the main resources and conditions influencing cultivated plant growth.
-To be able to quantify the different variables influencing mountain agricultural systems in the viewpoint of an efficient, sustainable agriculture.
-To be able of organize simple experiments in order to quantify plant and animal impacts on the agroecosystems.
-To be able of conceive scenarios with modifications in land use and climate, for the optimization of the agricultural system services in a changing world.

-The mountain landscapes as affected by historical land use. Formations created and maintained by human activities.                                                                           –Different cultivation approaches in mountain ranges: organic and conventional agriculture.                                                                                                                      -Optimization of the resource use efficiency in cultivated ecosystems. Best management practices.  Assessment of sustainability in agriculture.                                                                                              
-The animal and human-induced impacts on ecosystem functioning. Interactions between ecosystem biotic components: direct and indirect interactions.                                                                                                                                                                                                                                       -The trade-off between agricultural production, biodiversity and regulation of biogeochemical cycles.
-The application of the concept of ecosystem in the study of biotic/abiotic interactions. The solar radiation and the atmosphere. The Liebig’s law and the limiting factors. Favourable and unfavourable, direct and indirect biotic interactions.
-The energy budget and its quantification. The available energy, the albedo, the Stefan-Boltzman law.
-The hydrological budget and its quantification, with special reference to evapotranspiration. The Penman-Monteith equation.
-The carbon budget and its quantification. The net ecosystem production and the net ecosystem carbon balance.                                                                              -The measurement and modelling of ecosystem properties and functions: direct measurement, proximal sensing and remote sensing.
-The measurement of matter and energy exchange at leaf and canopy level. Reflectance indices. Fluorescence based estimates of vegetation activity. Biogeochemical modelling. Model-data fusion.

The course will be composed of two-thirds frontal lectures with PowerPoint presentation slides, one-third field excursions, laboratory and computational activities.
