Welcome to Part 3 of the interactive lecture on Soil, Water and Food Security by Prof. Dr.-Ing. Ralf Otterpohl. In this part, you learn more about regenerative agriculture. The following key questions and more will be answered in this lecture:

• How do we define organic agriculture?
• What is regenerative agriculture?
• What is agroforestry?
• Why do we need reproductive seeds?
• What are rainwater harvesting techniques?

Therefore, this lecture introduces regenerative agricultural practices, such as organic agriculture, agroforestry, rainwater harvesting and keyline systems. Additional aspects of regenerative agriculture, such as the building of humus, the potential role of mycorrhiza fungi, or avoidance of tillage practices are discussed, among other.
