Desertification and land degradation

(Referents Prof. Giovanna Seddaiu and Giovanni Garau)

The lines of research mostly concern:

The research topics of this curriculum are dedicated on all the forms of land degradation, intended as the loss of actual or potential land productivity or utility as a result of natural or anthropic factors which affect food production and safety, livelihoods, and the production and provision of other ecosystem goods and services. In this context, desertification is a form of land degradation occurring in arid, semi-arid and dry sub-humid areas worldwide.

The specific research lines of the curriculum are:

-       Factors and forces leading to land degradation and desertification

-       Impacts of climate change on land degradation and desertification

-       Monitoring and assessment methodologies at different scales (from field to landscape)

-       Mitigation and adaptation strategies to cope with land degradation and desertification

-       Socio-economic and policy dimensions of land degradation and desertification

 

Common objectives

The common objective of the Course is to deepen interdisciplinary competences of the Agricultural Sciences, acquired in specific laboratories and in the open field (experimental companies) as well as in liaison with affiliated agencies and research agencies, under the supervision of an academic mentor. The PhD program in Agricultural Sciences also promotes internationalization through the carrying out of research periods abroad, the preparation of co-tutoring agreements with foreign researchers, the stipulation of agreements with foreign universities and research institutions and the presence in the board of professors of researchers from National and International universities and research institutions.

Teaching goals

The course aims to train experts in research and high professional qualifications in the following fields (albeit not exclusively): agrometeorology and plant ecophysiology; cropping systems; plant health; management and protection of agricultural and forest production systems; conservation, protection and enhancement of natural resources; sustainable water management; biotechnologies aimed at regional, national and international production needs; breeding techniques, livestock feeding, selection and selection of livestock animals also with the use of molecular biology techniques, quality and safety of food and feed products; desertification and soil degradation, economics of land degradation.

In the three years the PhD students acquire the scientific method and the skills for the preparation of experimental projects, the conduct of experimental plans and laboratory activities, the processing of data and the evaluation of statistical-experimental inferences, the disclosure of the facts of the research. according to international standards.

Language

A good command of English is required for admission to the course. This includes 3 compulsory common courses taught entirely in English to improve communication and oral comprehension and use of scientific English in terms of: i) reading and understanding of scientific texts; ii) writing of scientific texts; iii) oral communication in scientific forums.

All courses are taught with bilingual material - Italian / English - and teachers use both languages during lessons. PhD students can attend the University Linguistic Center for a linguistic study.

 

TEACHING

The training of the Course is divided into three years and aims to train figures able to contribute to innovation and to the scientific and technological development of society. Every year for the new Doctoral Cycle activated, the Teaching Plan is formulated for a period of three years.

The preparation of the PhD students is aimed at research oriented both towards university teaching and for inclusion in public and private research institutions, both in the industrial and service world.

The total teaching commitment is 180 Research Training Credits (CFR). For admission to the second year, 42 CFR are required and admission to the third 102 CFR. All CFR must be achieved within the third year of the course. For courses which are common to the addresses and specific to the 1CFR address = 8 hours of teaching and 25 hours of the doctoral candidate's total commitment. Attendance is mandatory. A maximum of 25% is allowed on the total time of the scheduled lessons, with attendance of at least 75% for each course.

For PhD students without scholarship, the compulsory attendance is at least 30% of each course.

To encourage stays abroad and internships, doctoral students who do not attend scheduled classes as they are engaged in research activities elsewhere are admitted and must still take the final exams. In addition, the PhD student who has attended courses like those of the Course, arranged by the host institution, can request the evaluation of the accrued CFR. The decision on the evaluation will be taken by the Board of the Course.

They can be evaluated among the CFRs at the choice of the PhD student courses used outside the Course. Courses that require access to the master's degree and which include a final exam are eligible. The recognition of the number of CFR is delegated to the Board of the Course.

At the end of each academic year the student must produce a report of the activities carried out during the year. The report is evaluated by the Board for admission to the following year and the recognition of the CFR for the research activity.
