The Softest Power
Green Wall is a landscape strategy to control and reduce the severity of wind storms along roadways and across other open landscapes. The sheet metal wind breaks calm and reduce dust transport in winds and structure a suitable microhabitat for the propagation of new trees, which when full grown, will replace the function of the sheet metal walls.
The ubiquitous corrugated metal sheets used for perimeter security barrier walls are here redeployed to make an instant shelterbelt. The effect of wind calming results in dust deposition and supports vegetal growth, in this case almond trees are established. The almond tree is a traditionally plant which was widely cultivated in Afghanistan. The Kabul North International Airport Road acts as a first line of defense and demonstrates how vegetation can mitigate wind storms, while improving airport safety, local mobility, and can provide economic development opportunities.
