Across Australia the water cycle is broken. Extreme events, hot days, floods, droughts have increased. The pattern and nature of rainfall has changed. Particularly of the winter rain. What has caused this change, and it is not Greenhouse Gases, it is how water is held on the land which causes the loss of the small or local water cycle. This directly relates to how we have managed agricultural land in the last 30 years. The science of landscape hydration and the process of reversal is discussed. Particularly attention will be paid to the process of the impact of biology on the intensity and amount of rain.
Landscape rehydration has occurred both here and around the world. Lessons from these examples are presented with particularly regard to their biogeomorphological impact on hydration.
In this HydroTerra webinar, Phil Mulvey presents the argument that to better manage floods, we must focus on the upper catchment to reduce rainfall intensity and increase infiltration; prioritising water retention, slowing river flow, and recharging alluvium.

Soil pH affects everything—from plant growth to stock health. But many farmers don’t realise how dramatic the impacts are… or how to test for it properly. In this episode, we dive into the fundamentals of soil pH, how it works, and how to measure it right on your farm.
