Earth’s climate is changing, whether you like it or not. As it does, other changes – like rising sea levels or falling crop yields – follow. It is easy to see how this might lead to conflict. Competition for ever scarcer resources such as arable land and its bounty can turn ugly. As the price of food rises the poor, who spend more of their income on it, are hit more than the rich, exacerbating income inequality and leading to disaffection, resentment and, possibly, violence.

In a recent post on the new United Nations population projections, I discussed the risk in assuming that countries in sub-Saharan Africa will progress through the demographic transition at a pace similar to other regions. Making this assumption is questionable because fertility decline in Africa has generally proceeded more slowly than in other parts of the world, with several cases of “stalls” and even small fertility increases over time.

Water, energy, and food – this “nexus” of interrelated resource issues continues to garner attention from analysts, policymakers, and the media. Over the next four decades global population is projected to increase to about 9.6 billion and, worldwide, demand for water is projected to increase 55 percent; energy, 80 percent; and food, 60 percent. In a new video about the first of a series of workshops on this nexus, the International Union for Conservation on Nature and the International Water Association explain how they are working to bring together private and public sector water infrastructure experts from across Africa and the world to build partnerships and create some consensus on a “nexus-based approach” to managing scarce resources.

During the Gezi Park protests last month in Istanbul, Turks and Kurds dismissed historical mistrust and banded together against Prime Minister Erdogan’s growing authoritarianism. Some have suggested the newly unifying cause has strengthened momentum for a long-standing solution to Kurdish autonomy and rights in Turkey. Still it may be water that the fate of Kurdish ambitions is most tied to, rather than officials in Ankara or protestors in Istanbul.

June and July are traditionally slow in Washington, but not this year: ECSP and GHI hosted several big events at the Wilson Center, Roger-Mark traveled to the ICPD Human Rights Conference, and the UN released new population projections – coverage of which all made the top 10 most popular posts last month. Also joining the top 10 were two posts from the China Environment Forum and a cross-post from ChinaDialogue. Clearly China’s natural resource and climate change challenges are the minds of many. The final newcomer is Elizabeth L. Chalecki’s preview of her new primer on environmental security.

Cambodia to grow by nearly one-third by 2050; Kenya to more than double; Mali to swell to three times its current size. These were the population projections available when Feed the Future, President Obama’s global hunger and food security initiative, was beginning implementation in 19 focus countries around the globe in 2010.
