On a warm January afternoon, Tesema Merga, a village elder in Endibir, Ethiopia, surveyed the latest improvements to the long dirt road just outside his house. Eventually this road will be paved, which will bring significant changes to the community.

Frequent readers of New Security Beat are no strangers to the PHE approach to development – projects, often community-based, that integrate population, health, and environmental programming in a single intervention. Practitioners suggest that such integrated programming is more effective and efficient than running simultaneous siloed projects, each focusing on a narrower objective. But does the evidence support this conclusion? How effective is the PHE approach?

East African countries like Kenya have made great strides in recent decades in increasing access to modern contraception, leading to marked declines in fertility rates. But disparities remain.

In high-income countries, as many as 10 to 15 percent of women experience depression, anxiety, or other non-psychotic mental health challenges during pregnancy or the year after giving birth. In developing countries, the chances rise to 16 percent of pregnant women and 20 percent of post-natal women, according to Jane Fisher, professor of women’s health at Monash University in Melbourne, Australia. [Video Below]

The state of maternal health in South Asia is difficult to assess. Although rates of maternal mortality are declining between 2 and 2.5 percent a year overall, the region’s massive population – one fifth of the world and over 1 billion people in India alone – means it still accounts for one out of three maternal deaths. [Video Below]

As “resilience” builds as a theme for the development community, a few key concepts are rising to the top of the conversation. [Video Below]

In 1941, glacial Lake Palcacocha in the Peruvian Andes burst its moraine dam of earth and stones, sending a torrent of water through the city of Huaraz and killing an estimated 5,000 people. Between 1941 and 1950, two more glacial lake outburst floods, or GLOFs, which can occur after enough water fills in behind a glacier’s end moraine, killed another 5,000 people in the Cordillera Blanca. In response, the government set up one of the most effective glaciological units in the world with the goal of preventing future outburst floods. Using drain pipes, reinforced terminal moraine dams, sophisticated tunnels, and valve systems, they drained or contained 34 lakes in the region. As a result, thousands of lives were saved.
