The Wilson Center Policy Briefs are a series of short analyses of critical global issues facing the next administration that will run until inauguration day.

Seven billion people now live on Earth, only a dozen years after the global population hit six billion. But this milestone is not about sheer numbers. Demographic trends will significantly affect the planet’s resources and people’s security.

Despite progress over the years, Ethiopia’s Guraghe zone, located in the Southern Nations, Nationalities, and People’s Region, faces many development challenges. As senior monitoring and evaluation officer in the Guraghe People’s Self-help Development Organization (GPSDO), I have been working in this region for more than five years trying to reduce poverty and improve socio-economic development.

In the tiny tortillerias of this city, people complain ceaselessly about the high price of corn. Just three years ago, one quetzal – about 15 cents – bought eight tortillas; today it buys only four. And eggs have tripled in price because chickens eat corn feed.

Last month, Oxfam made an extraordinary request. It asked the World Bank to freeze its investments in agricultural land.

Stahl was one of three graduate students presenting their winning papers for an annual academic paper competition, “Reducing Urban Poverty,” co-sponsored by the Wilson Center, USAID, International Housing Coalition, Cities Alliance, and the World Bank.
