The climate is changing. But what does this mean? What are the causes of climate change and what can we do about it?
What is rainwater harvesting?
Rainwater harvesting is a technique which prevents rainwater to run off.
Instead, the water is collected and stored, so it can be used by vegetation, animals or people.
Rainwater harvesting is mostly performed in arid or semi-arid climates, since these areas have low water contents in the soil. This causes water shortage for humans, animals and plants. There are two different ways by which rainwater can be harvested. The first one is to apply soil management strategies which enable direct capture of the rainwater within the soil. This prevents the water from running off and enhances the infiltration into the soil. It is also possible to harvest the rain on one place and store it at another. For example, capturing the rainwater from a rooftop and store it within a cistern. This water is mostly used for watering crops or drinking.
