With over 400 people per square kilometer, the highest rate on the African mainland, population density is perhaps the most widely-discussed factor of Rwanda’s demography. Some scholars, notably Jared Diamond, have argued that it played a primary role in sparking the 1994 genocide through competition for land (although others present a more complex theory based in policies and governance).

“The traditional strategies for improving the health system include the horizontal approach, which prioritizes non-communicable diseases, and the vertical approach which prioritizes communicable diseases such as HIV/AIDS,” said John Townsend, vice president of reproductive health programs at Population Council, during a webcast discussion – the second in a series – between the Woodrow Wilson Center in Washington, DC, and maternal health experts in Nairobi, Kenya.

Mr. Pascal Gakwaya Kalisa has produced coffee in the densely populated country of Rwanda for the past nine years. A proud member of the 1,200 member Maraba Coffee Cooperative in Huye District in the Southern Province of Rwanda, Kalisa knows that a larger income alone does not ensure a better quality of life for his fellow coffee farmers and their families. He also knows that a successful coffee growing/exporting enterprise depends on preserving the fragile Rwandan soils, as well as on the health and well-being of farming families and communities. Therefore, Kalisa and other cooperative members treat the land and trees with a level of personal care that is necessary for optimum organic production and soil preservation.

The world’s women will determine whether the global population in 2050 is as low as 8 billion or as high as 11 billion through their choices (or lack thereof) about the number and timing of their children. Women in developing regions of the world will have the greatest effect on these potential population trajectories. Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged.

The mwami remembers when he was a king of sorts. His judgment was sovereign, his power unassailable. Since 1954 he, like his father and grandfather before him, has been the head of the Bashali chiefdom in the Masisi District, an undulating pastoral region in eastern Democratic Republic of the Congo (DRC). Though his name is Sylvestre Bashali Mokoto, the other chiefs address him as simply doyen – seniormost. For much of his adult life, the mwami received newcomers to his district. They brought him livestock or other gifts. He in turn parceled out land as he saw fit.

In a two–part Water International special report on water, food, and poverty, examining 10 of the world’s major river basins, a team of researchers say that instead of worrying about having enough water to sustain the world’s growing demand, policymakers should be concerned with understanding how to manage what they already have.

The Rwanda 2010 Demographic Health Survey is the latest in a regular series of DHS surveys that began in 1992, although hostilities had delayed the next survey until 2000. The 2010 survey interviewed 13,671 women ages 15 to 49 and 6,329 men ages 15 to 59 from September 2010 to March 2011. The total fertility rate (TFR – the average number of children would bear in her lifetime if the birth rate of a particular year were to remain constant) obtained in the survey was 4.6 for the three-year period preceding the survey. For urban women, the TFR was 3.4 and for rural women, who were 85 percent of the sample, 4.8.

From a demographic perspective, the global distribution of intrastate conflicts is not what it used to be. During the latter half of the 20th century, the states with the most youthful populations (median age of 25.0 years or less) were consistently the most at risk of being engaged in civil or ethnoreligious conflict (circumstances where either ethnic or religious factors, or both, come into play). However, this tight relationship has loosened over the past decade, with the propensity of conflict rising significantly for countries with intermediate age structures (median age 25.1 to 35.0 years) and actually dipping for those with youthful age structures (see Figure 1 below).
