At last year's United Nations General Assembly summit, world leaders promised to cooperate on ensuring safe, orderly, regular and responsible migration. This year, they need to do more to realize that pledge.

U.N. member states have acknowledged migration's many benefits, including its role in stabilizing global labor markets, spreading knowledge and ideas, creating diasporas that spur increased trade and investment, and sustaining economies worldwide through remittances, which pay for family members' health care, education and housing back home.

But these benefits are easily squandered if, as we've seen recently with crises in the Mediterranean Sea, the Andaman Sea, the Central American corridor, the Sahel and the Horn of Africa, migration is not governed responsibly and cooperatively.
