Humus per la Biosfera – A new Pond: Retention Basin, Water Reservoir and Habitat
In the winter of 2022/23, we created an irrigation pond in the upper area of our agricultural trial field near Bronte, opposite Mount Etna. This measure in preparation for the establishment of multifunctional hedges also has multiple benefits: As a retention basin, the pond holds back water in times of heavy rainfall and prevents soil erosion, it stores carbon and has a balancing effect on the microclimate, and it promotes biodiversity, e.g. as a spawning ground for amphibians in spring or a settlement site for moisture-loving spontaneous vegetation.
In summer, the pond provides the collected rainwater for plant irrigation as an alternative to the usual water extraction from the Simeto River in this area. The slope of the terrain allows the water to be directed to the plants without a pump. It will reach each hedge plant individually via a low-evaporation drip irrigation system and save them through the hot summers until they will be big enough to take care of themselves after a few years.
