KULeuvenX: As above, so below: An introduction to soils, ecosystems and livelihoods in the Tropics

The tropics are as beautiful and diverse below-ground as they are above-ground. Learn how to use knowledge about the natural variability in soil properties for the sustainable management of ecosystems and farms.

About this course

Skip About this course

Soils form the foundation of sustainable development. They grow our food, fiber and fuel, are a habitat for organisms, buffer and purify water and safeguard archaeological legacies. It is therefore of vital importance to understand how soil properties vary across tropical ecosystems and landscapes, and how these properties affect biodiversity and livelihoods. So if you want to understand tropical soils and want to learn how to keep those soils healthy, this course is for you! You'll need basic knowledge of life sciences.

In this course, we will go on virtual excursions to explore the major soils of five biomes: forests, mountains, grasslands, deserts, and wetlands. With the support of JRC and FAO, instructors from KU Leuven and ISRIC will explain which soils develop under certain conditions, what their most important traits are and how those insights can make land use more sustainable. Our partners from different research projects all over the tropics moreover will introduce you to their work and show you real-life examples of how they apply soil knowledge through engaging videos and case studies.

Through this course you will:

  • Understand how soils are formed and why they occur in certain climates and landscape positions
  • Learn to recognize and classify the major soils of the world (WRB 2016)
  • Learn to determine the opportunities and challenges of each soil type in relation to biodiversity, livelihoods, and management

"As an outsider of the discipline, I couldn't find a better opportunity to both resume my basics and enrich them with more insights on soils in the Tropics. An important strength of the course was how it wonderfully linked knowledge on soil properties to the livelihoods of people inhabiting and/or using the landscape. This has put great emphasis on the importance of a constant 'knowledge cooperation' with local populations and on enhancing a responsible use of natural resources." - Previous learner
