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.

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.

According to the UN, the planet has warmed faster since the turn of the century than any other period on record. Sea-level rise has also increased pace to 0.12 inches a year – almost double the rate observed during the 20^th century. This “unprecedented” rate of climate change is expected to disproportionally impact developing countries, whose socio-economic, political, and physical landscapes make them particularly vulnerable to the effects. The GAIN Index, an interactive mapping tool recently acquired by the University of Notre Dame, can help policymakers prepare for these changes by comparing the climate change vulnerability and readiness of countries around the world.

A newly released nationwide health survey of Haiti shows continuing positive trends on key health-care indicators in particular those of Haitian women and children. The latest survey, undertaken by the Haitian Ministry of Public Health and Population, was conducted in 2012 and compares with the prior survey done in 2006. It shows steady improvements among key indicators despite significant health challenges in Haiti due to the 2010 earthquake and cholera outbreak. Of note were improved indicators for child vaccination and malnutrition, infant and child mortality, women’s health, and contraception use. The report indicated no increase in HIV prevalence, which remained steady.

Fire needs oxygen to burn. When a fire starts inside a building, the floors, ceilings, walls, doors, and windows can constrict the flow of air. Breaking in to fight the fire thus carries the risk of opening a new airway. If that happens, a smoldering fire can expand explosively, bursting into roaring flames as it sucks air in through the new passageway. This sudden inrush of air to fuel a burst of fire has a name: backdraft.

I first visited Peru’s Alto Mayo Protected Forest in 2008. At the time, deforestation rates there were among the highest in the country. CI-Peru wanted to find a way to help communities and Peru’s National Service of Natural Protected Areas (SERNANP) keep their trees standing.
