With the help of international aid, foreign land grabs in the Gambella region of Ethiopia have resulted in environmental degradation, more severe economic and social inequality, and human rights abuses, according to a new study by the Oakland Institute. We Say The Land Is Not Yours collects testimony from victims of “villagization,” a policy of forced displacement started under the military Derg dictatorship and, according to many, continued to this day under the guise of land investment.

Among the few bright spots in the 2015 Freedom in the World Report, the brightest may be Tunisia, which for the first time was assessed as “free” – Freedom House’s highest “freedom status” and for many political scientists the definitive indication of a liberal democracy. Tunisia is the only North African state to have been assessed as free since Freedom House began its worldwide assessment of political rights and civil liberties in 1972, and only the second Arab-majority state since Lebanon was rated free from 1974 to 1976.

Sub-Saharan Africa is often characterized as an outlier in terms of population dynamics and reproductive health. While women are having fewer children around the world, even prompting some places to begin worrying about aging populations, the demographic transition is proceeding more slowly in Africa. Fertility rates in North and Southern Africa have declined to around three children per woman, but the three other sub-regions of the continent – East, Central, and West Africa – retain much higher fertility, between five and six children per woman. Whether, and how quickly, fertility rates decline in these regions over the next few decades will in large part determine the peak of world population. These regions’ demographic trajectories also have important implications for health, governance, food security, economic development, land use, climate vulnerability, and even security.

I distinctly remember the night I saw An Inconvenient Truth in 2006. The film essentially did what no high school teacher could: gave me a purpose to structure my studies, setting me on course to earn a degree in environmental studies, an advanced degree in natural resource conservation, and eventually working here, at the Wilson Center.

If you were on a mission to improve the plight of humankind, no less, would you care about how many people are living, where they are, and how old they are? You probably would, for it would obviously make it easier for you to estimate the challenge you face. However, the international community did not.

Global trends, from climate change and population dynamics to food, water, and energy scarcity, threaten to complicate global security, diplomatic efforts, and development policy. In the United States we are increasingly responding to these trends, rather than anticipating and planning for them.
