This report focuses on making the case for climate adaptation, providing specific insights and recommendations in key sectors: food security, the natural environment, water, cities and urban areas, infrastructure, disaster risk management, and finance. It is designed to inspire action among decision-makers, including heads of state and government officials, mayors, business executives, investors, and community leaders.

Consider:
• Without adaptation, climate change may depress growth in global agriculture yields up to 30 percent by 2050. The 500
million small farms around the world will be most affected.
• The number of people who may lack sufficient water, at least one month per year, will soar from 3.6 billion today to
more than 5 billion by 2050.
• Rising seas and greater storm surges could force hundreds of millions of people in coastal cities from their homes,
with a total cost to coastal urban areas of more than $1 trillion each year by 2050.
• Climate change could push more than 100 million people within developing countries below the poverty line by 2030.
The costs of climate change on people and the economy are clear. The toll on human life is irrefutable. The question is how will the world respond: Will we delay and pay more or plan ahead and prosper?
