Migration is an expanding global reality which allows millions of people to seek new opportunities, but it also involves challenges for migrants and societies. Are there specific policy directions that governments should keep in mind to maximize the opportunities migration brings while minimizing its challenges? Can investments help make migration a voluntary choice and not a desperate need or a last resort? By looking at how internal and international migratory flows link to economic development, demographic change, and natural-resource pressure, The State of Food and Agriculture 2018, explores answers to these questions. The report also provides a thorough analysis of the factors which contribute to migration decisions and recommends tailored policy and investment responses to make migration work for all.
