Investments that boost a country's gross domestic product do little to alleviate child malnutrition, with each 5% increase in GDP reducing stunting by less than 1%, says a study led by Subu Subramanian, a Harvard School of Public Health professor. More investment needs to be made in sanitation, clean water, promotion of breast-feeding and food aid programs, the study says.
As lawmakers consider revamping the U.S. immigration system, some are concerned about the possible impact of giving people who are living in the country illegally a way to become citizens. But others suggest such a policy is unlikely to cause a significant uptick in illegal immigration because birthrates in Mexico have dropped in recent years, U.S. jobs are no longer plentiful and crossing the border has become increasingly difficult. "It's a new Mexico, it's a new United States, and the interaction between them is new," said Vanderbilt University sociologist Katharine Donato.
Development aid from wealthy countries dipped for the second year in a row, declining by 4% in 2012, says the Organisation for Economic Cooperation and Development. However, "nine countries still managed to increase their aid," says Angel Gurría, the OECD secretary-general. Aid assistance shifted toward middle-income countries such as China, India and Indonesia, OECD says.
Development experts say tactics such as a homegrown food supply, empowerment of women and school food programs are strategies that can help protect impoverished Bangladeshis from higher food prices. Bangladesh faces serious challenges from chronic and acute malnutrition, with 60% of Bangladeshi households without access to sufficient food supply in 2010, according to studies.
The U.N. projects that the world population will reach 10.1 billion by 2100. Nearer-term projections include 9.3 billion people by 2050 and 7 billion on Oct. 31. "High-fertility countries" such as India and in sub-Saharan Africa, in particular, will fuel the expected increases, U.N. officials said.
