AGRONOMIC PRACTICES FOR SOIL CONSERVATION

Academic Year 2024/2025 - Teacher: SARA LOMBARDO

Expected Learning Outcomes

The discipline aims to provide students with the knowledge and the ability to understand the elements of agronomic and environmental analysis of Mediterranean agroecosystems and the methodologies for soil protection and the fight against desertification. Part of the course aims at providing agronomic skills and the ability to understand and apply them for the identification and contrast to the processes of erosion and desertification in a context of safeguarding the territory, the environment, and the landscape, with particular reference to the Mediterranean environment. The course, therefore, aims to provide students with the ability to apply the knowledge acquired in future work contexts through the ability to find and use the data necessary to formulate solutions to concrete or abstract problems with independent judgment. During the course, group activities will be promoted aimed at deepening some issues and communicating with their peers, promoting communication skills, and undertaking advanced studies that can be used independently in working and academic contexts.

In particular, upon completion of the course, students will be able to: (i) represent the acquired knowledge and understanding skills related Principles and basic concepts of agronomy and agroecology; the relationships between erosion and desertification processes with organic matter and microorganisms in the soil; and possible agronomic strategies to mitigate soil fertility loss processes through conservation agriculture techniques.  (ii) apply the knowledge and understanding skills acquired to designs aimed at solving environmental and agricultural problems by maximizing the ecosystem services provided by soil conservation arrangements (windbreaks, mulching, grassing (cover crops) intercropping), at field, urban, farm and land scales;  (iii) collecting and interpreting data and information aimed at independently analyzing the dynamics, processes, and effects of interventions taking place in the area of intervention (Mediterranean environment) where anti-erosive interventions are designed and implemented spatial and temporal levels. Evaluating both their functional role and landscape aspect; critically assessing their environmental and social impact and any scientific and ethical implications, valuing systems management in regenerative soil fertility and resilient agro-ecological system in which they operate; (iv) The course thus aims to provide students with the ability to apply the knowledge acquired in future work contexts through the ability to find and use the necessary data to formulate solutions to problems of a concrete or abstract type with autonomous judgment, having the ability to communicate them to specialists and non-specialists; (v) develop, with specific reference to the contents of the discipline, learning skills that enable students to continue their university studies in subsequent cycles with a high degree of autonomy.

Course Structure

For teaching, various teaching models will be adopted based on: frontal lectures which will be accompanied, with the involvement of the class, by a cooperative learning approach with exercises and in-depth seminars conducted by professionals. To achieve an ability to apply knowledge, group work is planned with the possible preparation of papers and analysis of case studies.
If teaching were given remotely or in mixed mode, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Information for students with special needs, Specific Learning Disorders (SLD) and social anxiety.
To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the didactic objectives and specific needs.
