に伴って says one change comes with, or is caused by, another: 人口の増加に伴って、住宅が不足している, "along with population growth, there's a housing shortage".
It's a formal, written relative of につれて and とともに, and it's typical of news, reports and official explanations. 伴う means "to accompany".
It works for both gradual change (as the economy grows) and single events that bring consequences (the typhoon's approach, construction work).
Before a noun, it becomes に伴う: 工事に伴う騒音, "noise accompanying the construction". In formal writing, に伴い. On train and road notices, you'll often see 工事に伴い, "due to construction work".
