Responses to JPR Climate and Conflict Special Issue: François Gemenne (Sciences Po)
›
If you want a government to address something, make it a defense issue. No need to hold a PhD in political science to know that governments tend to give the highest priority to issues that involve national security interests – one can complain and whine about it, but that’s the way it is.

Much Ado About Conflict? Climate’s Links to Violence Reexamined
›Violence is on the wane in human affairs, even if slowly and irregularly. Could climate change reverse this trend? Pundits and politicians have raised the specter of havoc caused by rising temperature, erratic patterns of rainfall, and rising sea levels. In this way, so the story goes, climate change will produce famine and mass migration that threatens political stability and provokes violence. However, to date there is little evidence that the meteorological or agricultural conditions associated with climate change are actually a major source of violence.

Demography, Climate in the Spotlight at Planet Under Pressure
›March 27, 2012 // By Kayly OberLondon’s 2012 Planet Under Pressure conference, on all things global change – including climate, population, global risks, and food security – kicked off with a bang on March 26 and ECSP was there to cover it. We’ll be here throughout the week following all of the most pertinent population, health, and security events – we invite you to visit our booth if you happen to be in London, join the conversation on Twitter (#Planet2012), and/or watch the livestream.
During the opening plenaries, UK Scientific Advisor and all-around environmental all-star Sir John Beddington was the first to introduce population into the discussion.
Speaking on “The Planet in 2050” panel, Beddington immediately noted that really 2050 is too far out and instead we should focus on the next two decades. Within these 20 years the trajectory of greenhouse gas emissions and climate change will be determined by the extent and manner of urbanization and demographic changes, particularly in Africa.
“How are we going to generate an infrastructure to feed 500 million Africans in the next 13 years?” Beddington asked.
Beddington’s talk could be considered a rejoinder to his famous “perfect storm” analogy, outlined in The Guardian in 2009:Our food reserves are at a 50-year low, but by 2030 we need to be producing 50 percent more food. At the same time, we will need 50 percent more energy, and 30 percent more freshwater.
In a later session, “Securing Global Biodiversity,” Simon Stuart, chair of the species survival commission of the International Union for Conservation of Nature (IUCN), expanded on this “perfect storm” analogy.
There are dramatic problems out there, particularly with water and food, but energy also, and they are all intimately connected. You can’t think about dealing with one without considering the others. We must deal with all of these together.
He agreed that the global challenge of our day hinged on how human needs add pressures to the natural environment. Rising demand for energy, food, and freshwater not only influences climate change but also exerts unprecedented pressure on soil quality and biodiversity.
But although we’re impeded by major challenges, including “unsustainable economic models,” a lack of public support, and a massive need for investment in conservation, we have made some strides, Stuart said. The Convention on Biological Diversity’s strategic plan for biodiversity, established in 2010, sets 20 targets for biodiversity conservation by 2020. Stuart believes this is the beginning of acknowledging the urgency of addressing the threat to biodiversity.
Tim Coulson, professor of population biology at Imperial College London, compared the efficiency of either reducing fertility rates or per capita consumption to determine the best way to reduce humanity’s impact on the planet.
Coulson ran two simple simulations using India and the United States as case studies. In one model, he changed fertility rates by one percent per year for 50 years. In the other, he decreased per capita consumption by one percent per year for 50 years. What he found in both cases was that decreasing per capita consumption achieved the most rapid change in human impact on the environment. Nevertheless, he acknowledged that a longer-term course of action of declining fertility rates was needed to keep impact stable.
Readers beware, however – this type of experiment is an incredibly simplified exercise in the intersection of people and the environment. A more varied set of scenarios would produce more useful results. As Beddington mentioned, populations in sub-Saharan Africa have both the highest growth rates and the most direct impact on the environment due to their higher reliance on natural resources for livelihoods.
And, perhaps most importantly, as one commentator noted, these scenarios do not take into account cost factors. For instance, in order to reduce greenhouse gas emissions through more energy efficient buildings and transport, the United States would need to invest $1.1 trillion through 2030. Alternatively, the cost to provide for the 215 million women in developing countries who want to avoid pregnancy but are not using an effective means of contraception is estimated at $3.6 billion. Using the “wedge” climate model, meeting unmet family planning needs would be equivalent to the amount of greenhouse gas emissions saved by converting entirely to electric vehicles – at a fraction (about five percent) of the cost.
Stay tuned for more updates from ECSP at the Planet Under Pressure Conference. We’ll also be posting pictures from the conference to our Facebook and Flickr pages.

Global Water Security Calls for U.S. Leadership, Says Intelligence Assessment
›March 26, 2012 // By Schuyler NullAlongside and in support of Secretary Clinton’s announcement of a new State Department-led water security initiative last week was the release of a global water security assessment by the National Intelligence Council and Director of National Intelligence. The aim of the report? Answer the question: “How will water problems (shortages, poor water quality, or floods) impact U.S. national security interests over the next 30 years?”

Fourth World Water Development Report Released by UN
›The beginning of last week’s World Water Forum in Marseille also marked the release of UNESCO’s fourth edition of the World Water Development Report. Chief amongst the challenges outlined in the new report are meeting demand from growing population and consumption. Agriculture accounts for 70 percent of water usage, according to the report, and globally we will require 70 percent more food over the next 40 years, introducing the possibility of overtaxing already-stressed water resources – all while adapting to climate change. There are substantial gains to be had in increasing farm-to-table efficiency, especially in developing countries, the authors sagely point out, but the supply challenge remains a huge one.
This year’s edition also adds several new sections, including on women and water. “The crisis of scarcity, deteriorating water quality, the linkages between water and food security, and the need for improved governance are the most significant in the context of gender differences in access to and control over water resources,” write the authors. “These challenges are expected to become more intense in the future.”
The integrated nature of today’s water issues is a highlight throughout the report. “Accelerated change” will create new threats and “interconnected forces” create uncertainty and risk, but UNESCO emphasizes that if policymakers are made aware of these issues, ultimately “these forces can be managed effectively and can even generate vital opportunities and benefits through innovative approaches to allocation, use, and management of water.”

PBS ‘NewsHour’ and Pulitzer Center Examine Water Shortage and Health Issues in Ghana and Nigeria
›The PBS NewsHour continued its collaboration with the Pulitzer Center on Crisis Reporting on international reporting last week with an episode on water infrastructure in Ghana and Nigeria. The coverage is especially apropos on World Water Day.
Correspondent Steve Sapienza spoke to reporters in Ghana and Nigeria to highlight long-running access and sanitation issues in both countries caused by poor infrastructure that has not kept up with growth.
Ameto Akpe is a local reporter for Nigeria’s BusinessDay, where her stories “target the contradiction of a country with immense oil wealth and great water resources that are not reaching their citizens.” In the city of Makurdi, capital of the north-central Benue State, she reports on the hundreds of thousands of people who rely on either high-priced water delivery or untreated water drawn straight from the Benue River.
“The previous attempt to build a water treatment plant ended in scandal in 2008,” says Sapienza, “with an unfinished treatment facility and city officials unable to account for $6 million.”
“Unfortunately, the waterworks is only half of the solution to Makurdi’s water problem,” writes Akpe on the Pulitzer Center. “The other half is a system of pipes to deliver the water to the people – and that project is just a twinkle in the eye of a handful of contractors and bureaucrats.”
In Ghana, metro TV reporter Samuel Agyemang explains similar access and sanitation issues in the capitol of Accra and its suburb of Teshie, where some residents have waited decades for piped water, despite substantial foreign investments.
The Pulitzer Center’s Peter Sawyer explains in a companion piece that “the population of Accra has grown enormously in the past several decades. But the water supply system has not grown with it.” As a result, the Ghana Water Company is constantly playing catch-up to provide water to communities, many of whom do not understand how to demand accountability from their officials, says Agyemang.
According to UN estimates, Ghana’s population has increased by more than 10 million people since 1990. Nigeria is one of the fastest growing countries in the world, with 158 million people currently and the UN medium projection estimating a possible 389 million by mid-century.
Reporter Ameto Akpe will be speaking about Nigeria’s water and sanitation problems at an upcoming all-day event on Nigeria at the Wilson Center, scheduled for April 25.
