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.

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.

Hotspots: Population Growth in Areas of High Biodiversity
›More than one-fifth of the world’s population lives in biodiversity hotspots – “areas that are particularly rich in biodiversity and endemic species,” said John Williams of the University of California, Davis, at the Wilson Center on February 29. And those populations are growing faster than the global average. Add to that the fact that “biodiversity continues to decline globally, despite increasing investments in conservation,” said David Lopez-Carr of the University of California, Santa Barbara, and the need for new approaches to conservation becomes evident. [Video Below]
Williams and Lopez-Carr were joined by Dr. Vik Mohan, director of the sexual and reproductive health program for Blue Ventures, a London-based conservation nongovernment organization that works with communities on the remote western coast of Madagascar.
To respond to the demands of the communities and to better protect biodiversity hotspots, the speakers argued that conservation efforts need to incorporate health and livelihood services directed at the growing populations living nearby.
A Complex Relationship
“The relationship between population and biodiversity loss or conservation is a pretty complex relationship,” said Williams.
He offered Latin America and the Caribbean as an example of the multiple factors that can affect how population and biodiversity interact. Population growth in the region has slowed, and agricultural expansion is driving habitat loss as the population ages and urbanizes and as increasing per capita GDP contributes to higher levels of consumption.
In the Indo-Pacific region, stretching from East Asia to Australia, high population growth coupled with economic growth has coincided with an increase in the exploitation of rare species for illegal trade, according to Williams. And in Africa, where the population is growing quickly but without comparable economic growth and amid high levels of instability, subsistence drives ecological exploitation.
Biodiversity and Family Planning in Madagascar
“People who live in the biodiversity hotspots are typically poorer, typically have poorer access to healthcare than their counterparts in the cities or in the world at large, and typically have poorer health than those counterparts,” said Mohan.
Blue Ventures has been working in Madagascar since 2003. The island is one of the most biodiverse areas in the world; 80 percent of its plant and animal life is endemic, meaning it exists there and nowhere else, said Mohan. At the same time, Madagascar is one of sub-Saharan Africa’s fastest growing countries, with a population growth rate of 2.9 percent and an average total fertility rate of 4.6 children per woman.
Blue Ventures initially came to the country to improve conservation in the island’s coastal villages, where residents survive largely on subsistence fishing. But once there, the group quickly found that the population was “growing so rapidly that in spite of our best conservation efforts, the demand for those finite coastal resources [was] outstripping supply,” said Mohan.
“The number of people who are going out to catch fish to feed their to feed their families is going up exponentially, and those fisherman are having to work harder and harder to catch smaller fish that are farther and farther down the food web.”
Realizing that trend, Mohan said that “just by asking a few very basic questions, we unearthed a huge unmet need for healthcare and a huge unmet need for family planning in particular.”
In response, Mohan and his colleagues opened up a family planning clinic in Andavadoaka, one of the villages Blue Ventures serves. On the clinic’s first day, Mohan said, “20 percent of all women of reproductive age came asking for contraception.” Following that opening, they “rapidly found [that] this unmet need was mirrored in every single village along the coast that we worked in,” he said. Since then, modern contraceptive prevalence, initially about seven percent, has increased four-fold, while birth rates have fallen by about one-third. All in all, Mohan said, the population of the Velondriake region, where Blue Ventures operates, is five percent smaller now than it would have been without the group’s family planning services.
Rural Areas Driving Population Growth
Across the developing world, Lopez-Carr said that unmet need for family planning “remains significantly higher” in biodiversity hotspots. Given that high unmet need, especially in Africa, it is easy to infer that “conservation may be less sustainable…if it does not consider health,” he said.
In his ongoing research on population and biodiversity, Lopez-Carr looks at how fertility rates compare in and out of hotspot areas and between regional and local levels. At the country and province level, “high-value conservation areas do not have unusually high total fertility rates (TFRs),” he said. But at more localized levels, “in the most remote rural areas, TFRs remain high, and in many cases, in the most remote rural areas, the demand for family planning is still very low,” indicating that these areas are still in the early stages of their demographic transitions.
The fact that the sub-state picture can look so different from the state-level picture means that there is more work for researchers to do, said Lopez-Carr. “Where the fertility rates are highest is where we have the least data,” he said, and that has significant implications for understanding future population growth.
Looking at UN population projections, the world’s net population gains will be in its poorest cities, he said, but “virtually all this growth is going to be from migration, fueled by remaining high fertility in rural areas.” And “virtually all of that growth will be predicated upon the timing, magnitude, [and] pace of the fertility transition in rural areas.”
Better understanding the demographic picture in rural areas is therefore critical – not just to improving health and preserving biodiversity in the world’s hotspots, but to honing down more accurate global population projections as well.

Food Security in a Climate-Altered Future, Part Two: Population Projections Are Not Destiny
›March 20, 2012 // By Kathleen MogelgaardRead part one, on the food-population-climate vulnerability dynamics of Malawi and other “hotspots,” here.
Too often, discussions about future food security make only a passing reference to population growth. It is frequently framed as an inevitable force, a foregone conclusion – and a single future number is reported as gospel: nine billion people in 2050. But adhering to a single path of future population growth misses the opportunity to think more holistically about food security challenges and solutions. Several recent food security reports illustrate this oft-overlooked issue.
Accounting for Population a Challenge
Oxfam International’s Growing a Better Future: Food Justice in a Resource-Constrained World is a thorough and fascinating examination of failures in our current food system and future challenges related to production, equity, and resilience. It reports newly-commissioned research, carried out by modelers at the Institute of Development Studies, to assess future agricultural productivity and food prices given the anticipated impacts of climate change.
But both the modeling work and the report text utilize a single projection for population growth: the UN’s 2008 medium variant projection of 9.1 billion by 2050 (which has since been revised by the UN up to 9.3 billion). Early on, the report does recognize some degree of uncertainty about this number: “Greater investment in solutions that increase women’s empowerment and security – by improving access to education and health care in particular – will slow population growth and achieve stabilization at a lower level.” But such investments do not appear in the report’s overall recommendations or Oxfam’s food security agenda. This is perhaps a missed opportunity, since the range of possibilities for future population growth is wide: the UN’s low variant for 2050 is 8.1 billion, and the high variant is 10.6 billion.
Food Security, Farming, and Climate Change to 2050: Scenarios, Results, and Policy Options is another frequently-cited report published by the International Food Policy Research Institute in 2010. In recognizing that economic growth and demographic change have important implications for future food security, IFPRI researchers modeled multiple scenarios for the future: an “optimistic” scenario which embodies high GDP growth and low population growth, a “pessimistic” scenario with low GDP growth and high population growth, and a “baseline” scenario which incorporates moderate GDP growth and the UN’s medium population projection. Each of these scenarios was then combined with five different climate change scenarios to better understand a range of possible futures.
Using different socioeconomic scenarios enabled researchers to better understand the significance of socioeconomic variables for future food security outcomes. The first key message from the report is that “broad-based economic development is central to improvements in human well-being, including sustainable food security and resilience to climate change.” This focus on economic development is based in part on the “optimistic scenario,” which counts on high GDP and low population growth (translating to high rates of per capita GDP growth).
Unfortunately, the socioeconomic scenario construction for this analysis doesn’t allow for an independent assessment of the significance of slower population growth, since high population growth is paired only with low GDP and lower population growth is paired only with high GDP. Therefore, none of the report’s recommendations includes reference to reproductive health, women’s empowerment, or other interventions that would contribute directly to a slower population growth path.
Expanding the Conversation to Better Inform Policy
Without a more nuanced treatment of population projections in technical analysis and popular reporting on food security, decision-makers in the realm of food security may not be exposed to the idea that population growth, a factor so critical in many areas where food security is already a challenge, is a phenomenon that is responsive to policy and programmatic interventions – interventions that are based on human rights and connected to well-established and accepted development goals.
There are some positive signs that this conversation is evolving. A new climate change, food security, and population model developed by the Futures Group enables policymakers and program managers to quickly and easily assess the impact of slower population growth on a country’s future food requirements and rates of childhood malnutrition. In the case of Ethiopia, for example, the model demonstrates that by 2050, a slower population growth path would make up for the caloric shortfall that is likely to arise from the impact of climate change on agriculture and would cut in half the number of underweight children.
And recently, we’ve begun to see some of this more nuanced treatment of population, family planning, and food security linkages in a riveting, year-long reporting series (though perhaps unfortunately named), Food for 9 Billion, a collaboration between American Public Media’s Marketplace, Homelands Productions, the Center for Investigative Reporting, and PBS NewsHour.
In January, reporter Sam Eaton highlighted the success of integrated population-health-environment programs in the Philippines, such as those initiated by PATH Foundation Philippines, that are seeing great success in delivering community-based programs that promote food security through a combination of fisheries management and family planning service delivery. Reporting from the Philippines in an in-depth piece for PBS NewsHour, Eaton concluded:So maybe solving the world’s food problem isn’t just about solving the world’s food problem. It’s also about giving women the tools they want, so they can make the decisions they want – here in the world’s poorest places.
Making clear connections of this nature between population issues and the most pressing challenges of our day may be the missing link that will help to mobilize the political will and financial resources to finally fully meet women’s needs for family planning around the world – an effort that, if started today, can have ongoing benefits that will become only more significant over time. Integrating reproductive health services into food security programs and strategies is an important start.
Back in Malawi, just before we turned off the highway to the Lilongwe airport, I asked the taxi driver to pull over in front of a big billboard. We both smiled as we looked at the huge government-sponsored image of a woman embracing an infant. The billboard proclaimed: “No woman should die while giving life. Everyone has a role to play.” Exactly. The reproductive health services that save women’s lives are the same services that can slow population growth and bring food security within closer reach.
