Stacks of timber that had to be cut because of the draught in recent years and the infestation with the bark-beetle are pictured in the Westerwald mountain region near Weyerbusch, some 40 km east of Bonn, Germany, May 30, 2021. The construction sector is facing delivery problems partly linked to the strong economic rebound in many countries, which has pushed up global demand for timber, steel and other building materials.
