Learning outcomes
The program aims to develop an interdisciplinary knowledge and technical skills base for understanding soils resources and sustainable land management in a rural development context and from a systems perspective.
During the program problems of soil erosion, soil conservation, environmental degradation, sustainability and rural development issues are addressed from the farm to the catchment scale .
Course contents
