Desertification

Course manual 2021/2022

Course content

This course aims at learning the principles of geo-ecological field inventory and field measurements techniques. This will be illustrated within a field area where desertification is an important process. The course is a part of the semester focusing on water-related issues. In this course the results of water shortage, as expressed by groundwater over-drafting, irrigation, salinization, desiccation, and land degradation problems will be studied in the field. It addresses typical water-related issues in dryland regions, which is in contrast to the ecosystems which have an excess of water, and that are being dealt with in the other courses in the program. The course has also a function in providing a translation of landscape properties from the classroom to the field. As such it integrates earlier theoretically studied objects with real-world field conditions by carrying out an integrated landscape field inventory and analysis. Field experience is an important part of the education of earth and ecosystem science students and this course enables the development of required field skills. GIS techniques are used to handle field spatial data, both by preparation of pre-field material, as well as for collecting and processing field data and by implementing field knowledge into a model-based scenario study on the effects of climate change on desertification and biomass production.

General Layout

Introduction into the theoretical aspects of drylands and their threats such as desertification (land degradation, desiccation, salinization) in general and more specific for the field area to be studied. This is divided into the following sub-sets:

-In the course introduction an earth and ecosystem sciences framework for the landscape studied will be provided.

-Instruction and application of fieldwork in which geo-ecological field inventory techniques, along an illustrative gradient of landscapes including areas with different degrees of desertification vulnerability.

-Carrying out a climate scenario study using a simulation model for some of the sites studied in the field with emphasis on water availability and crop growth

-An introduction into measurement techniques to quantify soil degradation, desiccation, water quality parameters, and desertification processes and patterns, and the application of one or more of these methods in a spatial setting.

-Providing an explanation of the produced geo-ecological maps and elucidating the areas’ vulnerability to desertification

Objectives

• Apply theoretical concepts of earth and ecosystem sciences in a landscape study.
• Make an inventory of landscapes in order to relate substratum-soil-geomorphology-vegetation, land use and water availability.
• Integrate field observations in thematic maps with a written explanation of the produced maps.
• Understand the impact of climate and land use change on soil and vegetation with respect to desertification.
• Effectively co-operate in small research teams to efficiently collect and integrate data, and report results.
• Conduct vulnerability assessments of desertification threatened areas, using field data and quantitative approaches.
• Organize and integrate data in a clear and structured way.
• Apply field inventory techniques.

Attendance

Programme's requirements concerning attendance (OER-B):

• Participation in fieldwork is compulsory and cannot be replaced by assignments or other courses.
• In case of practical sessions, the student is obliged to attend at least of 90% of the sessions and to prepare himself adequately, unless indicated otherwise in the course manual. In case the student attends less than 90%, the practical sessions should be redone entirely.
• In case of tutorials/seminars with assignments, the student is obliged to attend at least 7 out of 8 seminars and to prepare thoroughly for these meetings, unless indicated otherwise in the course manual. If the course has more than 8 seminars, the student can miss up to 1 extra meeting for every (part of) 8 tutorials/seminars. If the students attends less than the mandatory tutorials/seminars, the course cannot be completed.

Additional requirements for this course:

The maximum number of practicals and laptop practicals that can be missed is 2. The entire fieldwork practical is mandatory.

Assessment

Assignments

Final Report

• The report is written jointly by the field team,

  Halfway through the reporting period feedback will be given on the draft report

  Feed-back will provided after the report has been submitted

Geo-database

• The geo-database is constructed by the field team and comprises the collector app data, and the GIS-based data

  The collector app data will be evaluated during and directly after the fieldwork. Halfway through the reporting period feedback will be given on the draft database

  Feedback will provided after the final version  has been submitted

Final field maps

• The final concept field maps have to be ready and approved before leaving the fieldwork area and will be assessed under part Field work 2

Fraud and plagiarism

The 'Regulations governing fraud and plagiarism for UvA students' applies to this course. This will be monitored carefully. Upon suspicion of fraud or plagiarism the Examinations Board of the programme will be informed. For the 'Regulations governing fraud and plagiarism for UvA students' see: www.student.uva.nl

Additional information

During the course, you will stay almost 2 weeks abroad continuously

The courses Plant-Soil Interactions, as well as Digital Earth, should have been followed for enrollment. The report of the Plant-Soil Practical course should be passed with at least a 6.0.

Maximum capacity: approx. 75 students
