Scientists have evidence supporting the widespread perception that trees make rain, that growing more vegetation, is how we get more rain.[1]

By growing more trees and other plant biomass across our landscapes, in our farms, gardens, and community open spaces, more water infiltrates and gets stored in our soil and vegetation. Retaining this water in our catchments, more water is then available for evaporation from the soil, leaf surfaces, and transpiration from plants. As a result, cloud cover increases, and we get more rainfall.

All great in principle – but forests are being cleared at a faster rate than at any time in history. How can we possibly reverse this by getting everybody to grow more plants? There’s 3 things we need to share:

  1. Science supporting the widespread perception that trees and other vegetation make rain
  2. Practical how-to for farmers and gardeners
  3. Economic benefits

Economic Benefits of growing Extra Vegetation

  1. Drought-Proofing – farmers and gardeners increase the amount of water infiltrating and stored in their soil, reducing irrigation, water, and stock feed costs.
  2. Yields improve and farmers and gardeners use the extra layers of vegetation to grow additional crops.
  3. Reduced fertiliser costs – as the structure and functioning of soil ecosystems improve so does the natural availability of plant nutrients in our soils.
