United Nations officials say Brasilia, the capital of Brazil, is one of a growing number of cities with water shortages. A U.N. report says water is in demand around the world as temperatures on Earth’s surface rise and demand grows along with populations. The report was released this week at the World Water Forum in Brasilia. The conference has been described as the world’s largest water-related event. Federal District Governor Rodrigo Rollemberg spoke at a panel discussion on Tuesday at the forum. He described water shortages as a worldwide problem. “Here in Brasilia, it is no different,” he added. The public water supply has less water because of low rainfall as well as fast and disorderly growth in Brasilia, which is part of the Federal District, Rollemberg said. In January 2016, after three years of little rain, district officials began limiting how much water people could use.
