Degraded land gets more rain than we think. In the Netherlands about 650mm of rain falls per year. Degraded land in Monterrey Mexico gets 680mm of rainfall per year. How is it that the Netherlands has less rainfall but the soil is more fertile?
The problem in these degraded areas is not the amount, but the problem is that the rain falls in peaks of about a couple of weeks. The next problem is that the rain falls on slopes through which it then flows into streams and rivers which flow into the sea. All this scarce fresh water disappears. When areas are eroded and degraded, there is often hard ground and only 20 to 25% of the water can infiltrate the ground.
When we look at history, traditional local communities took a much smarter approach. They solved this problem by creating terraces on slopes and mountains. When rain falls on these terraces, it gets a chance to sink into the ground. As a result, the water stays in the mountain and does not flow into rivers. If we do it the same way as traditional local communities, water infiltration will be much higher.
Existing terraces are being lost due to moving from rural areas to cities. Therefore, we have developed another way where you get the same result as the historical terraces. With the Groasis Terracedixx we can guarantee you that the rainwater no longer runs off the slope, but infiltrates the soil on a slope or mountain.
We are inspired by the traditional way of making terraces and therefore it brings an equal result. However, there are two important differences:
Instead of terracing manually, the Terracedixx creates a 'crack' 60cm deep with a channel next to it. This way we can break open the so-called hard top layer, allowing oxygen and water to easily infiltrate the soil. The channel collects the rainwater that flows down from the steep slopes and helps infiltrate into the ground. In addition, trees are planted in the 'crack' and thus have more water available to the tree.
For example, if you take an area where the average rainfall is 200mm per year, you have 2,000,000 liters per hectare at your disposal. Without terraces, 80% of the water is lost and flows into rivers. As a result, you lose 1,600,000 liters of water per hectare, while only 400,000 liters are available for trees.
With the mini terraces made with the Groasis Terracedixx, 20% of the rainfall is lost and flows away. There will then be not 400,000 liters available for the trees, but 1,600,000 liters.
This is an improvement of 1,200,000 liters per hectare = 300% more water available for trees!
Our goal is to plant 1 billion trees by 2035, helping restore ecosystems, combat climate change, and create sustainable communities worldwide.
Through innovative tree planting, we capture 40,000 kg of CO2 per hectare each year, reducing greenhouse gases and promoting a healthier climate.
We restore ecosystems and enhance biodiversity through sustainable practices, improving habitats for wildlife and ensuring a healthier planet for future generations.
