Evaluation is the lifeblood of any development effort – it’s how implementers know if they’re making a difference, determine what to do more or less of, and enables funders to evaluate cost-effectiveness. But it’s also an inexact science, no more so than when it comes to complex interventions that cut across sectors. [Video Below]

Half the world’s pigs – 476 million – reside in China. Increasingly prosperous consumers are eating fewer grains and demanding a more protein-rich diet, ballooning the pork industry to 15 times its 1960s-era size.

Outside of donor and humanitarian aid, South Sudan’s economy is almost entirely dependent on the oil sector – and that sector is in crisis.

Despite the fact that with proper interventions, the likelihood of mother-to-child transmission of HIV is less than five percent, expectant mothers with HIV or AIDS often face intense stigma and marginalization from health care providers around the world.

The emerging subfield of “security demographics” is interested in how demographic trends, such as youth bulges, high or low fertility rates, and sex ratios affect the security and stability of nation-states and regions. In our research, Andrea Den Boer and I have attempted to show that abnormally high sex ratios – situations where there are significantly more men than women – have been a security concern in the past and may affect security and stability in the future.
