IRRI-GATE

Once upon a time, there were farmers in Engaruka, Tanzania, who created a very efficient and articulated irrigation system from the river Engaruka, but at one point the society collapsed. WHAT happened? Archeologist and environmental scientists have been studied it for the last 30 years, but a conclusive explanation has not been found yet…climate change, environment degradation, population growth, conflicts..what happened??

we chose this story to show up the our research group activities at Yornight, the European night of researchers and engage kids in playing with water and an irrigation model, to simulate the effect of rainfall (climate) and forest on water flow..

can the study of the past teach us something about the future?

“forested” sponges worked perfectly as gates to divert the water, showing the importance of forests in draining water.

No surprise, lots of fun in playing with water!!

can young generation find solutions for the planet Earth?
