Monitoring of Agricultural Landscapes

04-GEO-APP2

Lecturer

Christopher Conrad

ECTS

5 ECTS

 

Aim

The module addresses methods on how Earth Observation and the use of geoinformation can support different fields of land and water management. Focus is set on remote sensing based concepts and methods for monitoring and supporting resource management in agricultural landscapes. Achievements and challenges are elaborated. The students will be guided to gain knowledge in selected practical examples.

 

Content

Mapping the parameters

  • Mapping cropland extent, cropland use, and cropping intensity at different scales
  • Rainfed agriculture, irrigated cropland or pasture? Disentangling of complex vegetation classes
  • Quantification of cropland production, status quo and developments
  • Aproaches to mapping land abandonment
  • More crop per drop? Assessing land and water use in irrigated landscapes

Remote sensing contributions to multi-sector assessments

  • Population growth and the competition for land in rural areas
  • Understanding the role of lakes and wetlands in agricultural landscapes
  • Vulnerabillity of agricultural landscapes under changing climate conditions
  • Crop yield predictions

Practical part on cropland use intensity in irrigation systems in Central Asia.

Coding

Small classification codes in R will be written (classification and accuracy assessment).

Software
