Start with the good news from this week’s finance for development conference in Addis Ababa: at least it got the narrative right.

Fear of mother-to-child transmission of HIV and other infectious diseases has been used as an excuse to deny women health care around the world. Some women living with HIV have even been sterilized without their knowledge. But with proper treatment, the chances of transmission to an unborn child are very low in many cases. The World Health Organization (WHO), in fact, just declared Cuba the first country to eliminate mother-to-child transmission of HIV and syphilis.

In 2007, the world crossed a threshold:  for the first time in human history, the majority of people lived in urban areas. Today, Africa and Asia are the only remaining continents where the rural population outnumbers urban, but they are urbanizing at unprecedented rates. This rapid growth is a double-edged sword. While urbanization spurs economic opportunity and often increases access to infrastructure, it is also widening disparities in health and development, according to a new data sheet by the Population Reference Bureau.

“With current neglect of family planning, the UN’s recent projection of a 2100 world population of up to 12.3 billion is a possibility,” says a report from the University of California, San Francisco’s Bixby Center for Global Reproductive Health. Increased voluntary family planning efforts are needed, the authors contend, to meet existing demand for contraceptives, stabilize the threat of global food insecurity, and reduce carbon emissions that contribute to climate change.

Since President Lyndon B. Johnson created the USAID population program in 1965, it has evolved in tandem with the global discourse on population and demography. “The agency’s family planning program is as relevant today as it ever was, and is necessary,” said Jennifer Adams, deputy assistant administrator of the U.S. Agency of International Development’s Bureau for Global Health. The bureau houses the Office of Population and Reproductive Health, which implements U.S. development and relief efforts to expand access to modern contraceptives, fight HIV/AIDS, reduce unsafe abortions, and protect the health of women and children.

Karachi, the world’s second largest city by population, is emerging from the grips of a deadly heatwave. A persistent low pressure system camped over the Arabian Sea stifled ocean breezes and brought temperatures in excess of 113°F (45°C) to the city of 23 million people in June. The searing heat disrupted electricity and water service, making life nearly unbearable. All told, officials estimate the heatwave killed at least 1,200 Pakistanis, more than twice as many as have died in terrorist attacks this year.

Iran is poised to reap a vast “demographic dividend” if the appropriate national and international policies are adopted, including a nuclear deal with the P5+1 (five permanent members of the UN Security Council, plus Germany).
