decrease owing » decrease lodging (Expand search), decrease during (Expand search), decrease in (Expand search)
owing defense » in defense (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
