Finding the Right Paddle: Navigating Climate Change Adaptation and Mitigation Strategies
›June 14, 2011 // By Christina Daggett
After decades on the periphery, climate change has made its way onto the national security stage. Yet, while the worlds of science, policy, and defense are awakening to the threats of rising sea levels, stronger storms, and record temperatures, debate continues over the means and extent of adaptation and mitigation programs. In a world of possibilities, how to decide which paddle to use to navigate uncertain waters?

Helping Hands: An Integrated Approach to Development
›Originally featured in the Wilson Center’s Centerpoint, June 2011.
“At the moment, the agendas of the growing population of people and the environment are too separate. People are thinking about one or the other,” said Sir John Sulston, Nobel laureate and chair of the Institute for Science, Ethics, and Innovation at the University of Manchester, in an interview with the Environmental Change and Security Program (ECSP).
“People argue about, ‘Should we consume less or should we have fewer people?’ The point is it’s both. We need to draw it together. It’s people and their activities.”
Many who research and work on population, health, and environment (PHE) issues are increasingly advocating integrated solutions. Such issues as population growth, natural resource management, and food security, are interrelated challenges that, if addressed concurrently, likely will yield better results and community trust.
With this notion in mind, ECSP launched the five-year HELPS (health, environment, livelihoods, population, and security) project in October 2010. The project focuses on integrated PHE programs and demographic security linkages. HELPS also looks at population’s links to global environmental priorities, media coverage of population, and related issues like gender, youth, and equity.
Funded by USAID’s Office of Population and Reproductive Health through its IDEA (Informing Decision-makers to Act) grant, the HELPS project builds on ECSP’s 14-year history of exploring nontraditional security issues.
Population-Environment Connection
A February event in the HELPS series featured Sir John Sulston, who said dialogue between population and environmental communities has received renewed attention and is reappearing on national agendas.
The Royal Society’s People and the Planet study, which will be completed by early 2012, will “provide policy guidance to decision-makers as far as possible” and aims to facilitate dialogue, he said. The HELPS Project is helping the working group gather evidence of population-environment connections and to identify solutions.
“What we should be aiming to do is to ensure that every individual on the planet can come to enjoy the same high quality of life whilst living within the Earth’s natural limits,” said Sulston. People are happier, healthier, and wealthier than ever before, according to human development indexes. But, Sulston said, 200 million women worldwide have an unmet need for family planning, ecosystems are degraded, biodiversity has decreased, and there are widespread shortages of food and water.
“Many times we tackle different development challenges through single sector programs: health programs, agriculture programs, water programs. Those single sector approaches can make sense,” said ECSP Director Geoff Dabelko on the Wilson Center’s Dialogue television program. “But, of course, poor people are facing all those life and death challenges at once. We have to find ways to help them meet those challenges together in an integrated fashion.”
On the same program, Roger-Mark De Souza, vice president for research and director of the Climate Program for Population Action International, said the drive for integrated development stems from the communities being served, not necessarily from outside aid groups. “We’ve seen that there’s a greater impact because there’s longer sustainability for those efforts that have an integrated approach,” he said. “There’s a greater understanding and a greater appreciation of the value that [PHE] projects bring.”
At an April 7 ECSP event, De Souza said rural communities in developing countries understand that high population growth rates, poor health, and environmental degradation are connected. An integrated approach to development, he said, is a “cost-effective intervention that we can do very easily, that responds to community needs that will have a huge impact that’s felt within a short period of time.”
Proponents of integrated development face significant barriers, but the tide may be turning. To fully harness this momentum, former ECSP Senior Program Associate Gib Clarke argues in his FOCUS brief, “Helping Hands: A Livelihood Approach to Population, Health, and Environment Programs,” that the PHE community must solidify its research base, reach out to new partners, and push for flexible funding and programming. He suggested changing the name PHE to HELP – health, environment, livelihoods, and population. By adding livelihoods, the glue that binds population, health, and the environment, he said, the HELP moniker might broaden its appeal to new donors and practitioners.
Case Study: Madagascar
In Madagascar, a key country for integrated PHE programs, “today’s challenges are even greater than those faced 25 years ago,” said Lisa Gaylord, director of program development at the Wildlife Conservation Society, at a March 28 Wilson Center event. As the country’s political situation has deteriorated since 2009, the United States and other donors pulled most funding, and some PHE programs were forced to discontinue environmental efforts.
But other PHE programs are expanding: Based in southwestern Madagascar, the Blue Ventures program began as an ecotourism outfit, said Program Coordinator Matt Erdman, but has since grown to incorporate marine conservation, family planning, and alternative livelihoods. A major challenge is its rapidly growing population, which threatens the residents’ health and food security, as well as the natural resources on which they depend. More than half the island’s population is younger than 15, and the infant and maternal mortality rates are high, Erdman said.
In response, Blue Ventures set up a family planning program. The program uses a combination of clinics, peer educators, theater presentations, and sporting events, such as soccer tournaments, to spread information about health and family planning. The HELPS project will soon publish a Focus brief on Blue Ventures’ family planning efforts, titled: “To Live with the Sea.”
Erdman said, “If you have good health, and family size is based on quality, families can be smaller and [there will be] less demand for natural resources, leading to a healthier environment.”
Demographic Security
A country’s age structure can pose a challenge, said Jennifer Dabbs Sciubba, the Mellon Environmental Fellow with the Department of International Studies at Rhodes College, at a March 14 Wilson Center event. Countries with a large percentage of people younger than 30 “are [much] more likely to experience civil conflict than states with more mature age structures.”
Tunisia’s recent revolution, Sciubba said, could be understood as a “story about demography.” Countries with transitional age structures, such as India, Brazil, and South Africa, face different security challenges. With a majority of their populations between 15 and 60 years old, more people are contributing to the economy than are taking away, which could bolster these countries economically and politically. Global institutions will have to reform and include these countries, she advised, “or else become irrelevant.”
“Understanding population is critical to our success in being able to prevent conflict, and also managing conflict and crises once we’re involved,” said Kathleen Hicks, Deputy Undersecretary at the Department of Defense (DOD). However, the DOD does not “treat demographics as destiny,” she said, but instead as “one of several key trends, the complex interplay of which may spark or exacerbate future conflicts.”
Demography can also help predict political trends. In 2008, demographer Richard Cincotta predicted that between 2010 and 2020 the states along the northern rim of Africa – Morocco, Algeria, Tunisia, Libya, and Egypt – would each reach a demographically measurable point where the presence of at least one liberal democracy among the five would be probable. Recent months have brought possible first steps to validate that prediction.
Mathew Burrows, counselor at the National Intelligence Council, said Cincotta’s work demonstrates that “the demographic tool is essential” to analysts and policymakers. “There is a real appetite among policymakers” for understanding demography, he said, because it gives them more structure than political science narratives.
Yemen is another example of this trend. In March, tens of thousands of youth-led demonstrators demanded that their president resign. While numerous factors have sparked the “Arab Spring,” one driving force is Yemen’s dire demographic and environmental situation. Some experts say Yemen may be the first country to run out of groundwater. The average Yemeni woman has more than five children, and 45 percent of its population is below age 15. On May 18, Yemeni and international experts discussed these issues at the Wilson Center. Upcoming HELPS events include daylong conferences on Afghanistan and Nigeria.
There are solutions that can break the links between “youth bulges” and insecurity. In a recent video interview discussing the connection between demography and civil conflict, Elizabeth Leahy Madsen, a senior research associate at Population Action International, said, “Policies that have a major impact over time are ensuring education, especially for girls, and providing employment opportunities to the large and growing numbers of young people today.”

Global Climate Change Vulnerability and the Risk of Conflict
›In a study from the Center for Sustainable Development at Uppsala University in Sweden titled “Climate Change and the Risk of Violent Conflicts in Southern Africa,” authors Ashok Swain, Ranjula Bali Swain, Anders Themnér, and Florian Krampe examine the potential for climate change and variability to act as a “threat multiplier” in the Zambezi River Basin. The report argues that “socio-economic and political problems are disproportionately multiplied by climate change/variability.” A reliance on agriculture, poor governance, weak institutions, polarized social identities, and economic challenges in the region are issues that may combine with climate change to increase the potential for conflict. Specifically, the report concludes that the Matableleland-North Province in Zimbabwe and Zambezia Province in Mozambique are the areas in the region most likely to experience climate-induced conflicts in the near future.The “Climate Vulnerability Monitor 2010: The State of the Climate Crisis,” published by Madrid-based DARA and the Climate Vulnerable Forum, is a comprehensive atlas of climate change vulnerability around the world. The report examines country vulnerability in four impact areas – health, weather disasters, habitat loss, and economic stress – and compares current levels of vulnerability with those expected in 2030. Of the 184 assessed countries, nearly all registered high vulnerability to at least one impact area. The report estimates that there are 350,000 “climate-related deaths” each year, almost 80 percent of which are children living in South Asia and sub-Saharan Africa. Finally, the report features an overview of climate change basics, country profiles, and reviews on the effectiveness of several climate adaptation methods. -
Book Launch: ‘Human Population: Its Influence on Biological Diversity’
›Measurements of “human population density and growth can be used to identify changes in the viability of native species, and more directly, in changes in ecological systems or habitat quality,” said Richard Cincotta, consultant at the Environmental Change and Security Program and demographer-in-residence at the Stimson Center, speaking at the book launch of Human Population: Its Influence on Biological Diversity.
Cincotta was joined by coeditor L.J. Gorenflo, associate professor of landscape architecture at Penn State University, and contributing author Christopher Small, research professor at the Lamont-Doherty Earth Observatory and adjunct professor at Columbia University, to discuss the book’s objectives, its diverse and multidisciplinary contributors, and its policy implications. [Video Below]
Establishing a Handbook for the Field
“Human Population: Its Influence on Biological Diversity establishes a handbook for the field,” said Cincotta. While the scientific volume is specifically geared towards researchers and conservation managers rather than policymakers, “there are a few Washington-type policy messages that are useful,” he added.
Human population affects biological diversity in multiple ways. While population density alone can be strongly indicative of the viability of different populations of native species, human activities and their chemical and energetic byproducts can also have a strong impact, even when human population density is low, said Cincotta.
Conserving Biodiversity in Different Settings
“Planned solutions, based on strategic actions, increasingly are essential,” said Gorenflo, a professor at Penn State University. “The days of letting nature take care itself are probably gone.” Gorenflo presented results from the two chapters he worked on: “Human Demography and Conservation in the Apache Highlands Ecoregion, U.S.-Mexico Borderlands” and “Exploring the Association Between People and Deforestation in Madagascar.”
“Population density seems to be a reasonably good indicator of biodiversity loss,” said Gorenflo. Data from the Apache Highland Ecoregion (a 12 million-hectare area located along the U.S.-Mexico border) indicate that biodiversity tends to drop off at population densities of more than 10 people per square kilometer. Conservation efforts in areas within the ecoregion that are at, or close to, this density threshold will likely encounter challenges to maintaining biodiversity, he said.
Human mobility is a major consideration, said Gorenflo: “Whereas high fertility can create population growth over generations, high mobility can create population growth in a matter of months or years.” In the Apache Highlands, for example, the 40 percent increase in population between 1990 and 2000 was largely caused by migration into U.S. cities in the region.
In Madagascar, Gorenflo and colleagues examined whether population growth and poverty were systematically driving deforestation and loss of biodiversity. Using data from the 1990s, they found that higher population density only slightly raises rates of deforestation and large increases in income only modestly decrease deforestation.
Not surprisingly, they found that the likelihood of deforestation decreased dramatically in protected areas. In addition, proximity to roads or footpaths was associated with significantly higher rates of deforestation. “Roads, footpaths, and protected areas are all policy decisions,” Gorenflo pointed out. “So when bilateral or multilateral organizations decide to invest in development in a place like Madagascar, they can look at these sorts of investments as being important.”
While there are some similarities to be drawn between regions’ experience with population and biodiversity, said Gorenflo, “every locality likely has a slightly different story; you need to do context-specific studies to get a real handle on what is going on.”
The Human Habitat
In his chapter, “The Human Habitat,” Christopher Small of the Lamont-Doherty Earth Observatory said his goal was “to set the stage for some of the more detailed studies by taking a look at the global distribution of human population.”
Using census data and satellite-derived maps of night lights to serve as a “proxy for development,” Small found that “people are everywhere, but they are not evenly distributed.”
At least half the world’s population lives on less than three percent of the inhabitable land, and most people live at densities between 100 and 1000 people per square kilometer. At both local and global scales, population density and city size are dominated by extremes: There are large numbers of small groups of people, and small numbers of large groups of people, he said.
“The environments where people live are more strongly correlated with features of the landscape than they are with climatic parameters,” said Small. While humans have effectively adapted to a range of climates, the majority of people tend to cluster close to rivers, at low elevations, and close to coastlines. Although it was once thought that three-quarters of the world’s population lived in coastal regions, Small’s results show that the actual number is close to half of these previous assumptions.
Understanding the spatial and environmental distribution of population and managing population growth may therefore help minimize negative impacts on specific habitats and biomes, said Small.

Aquaculture’s Promise for Food-Insecure Pakistan
›June 7, 2011 // By Wilson Center StaffThe original version of this article, by Michael Kugelman, appeared on Dawn.
“Give a man a fish and you feed him for a day,” the ancient Chinese philosopher Lao Tzu famously said. “Teach a man to fish and you feed him for a lifetime.”
For years, this adage has helped frame debates across a variety of disciplines. However, while globally influential, it is by no means universally applicable – as the sad realities of Sindh make painfully clear. In this parched, food-insecure region flush with fishermen and farmers, people have long known how to fish. The problem is that with water bodies shriveling up, there are increasingly fewer fish to catch. Many impoverished residents would be grateful for a single fish, given their struggles to secure a day’s worth of food.
Pakistan’s natural resource constraints know no provincial borders, yet they are notably severe in Sindh. Water tables are plummeting, with great volumes of Indus River flows diverted upstream to satiate agricultural and urban demand in Punjab.
Sindh’s water security is further threatened by population growth and global warming, and by the water-intensive, large-scale farming envisioned by foreign investors jockeying for agricultural land.
With surface water supplies threatened, users are increasingly tapping groundwater resources – yet according to the Pakistan Council of Research in Water Resources, a staggering 95 percent of the province’s shallow groundwater supplies are bacteriologically contaminated. This is unsurprising, given the technical deficiencies and inefficiency that characterize Sindh’s water treatment facilities.
In a province where so many livelihoods are tied to water availability and food production, water stress aggravates food insecurity and threatens economic well-being. A recent World Bank report concludes that Pakistan’s poorest spend at least 70 percent of their meager incomes on food – and undoubtedly many of them hail from Sindh. According to data from the Pakistan Agricultural Research Council, some of the province’s small farmers spend a whopping 87 percent of their incomes on food.

Measuring Ecosystem Vitality and Public Health With the Environmental Performance Index
›The Environmental Performance Index (EPI) is a comparative analytic tool for policymakers created jointly by Yale and Columbia Universities in collaboration with the World Economic Forum and Joint Research Centre of the European Commission. The EPI was created in 2006 and is updated biannually. Data is drawn from 25 performance indicators that fall under 10 well-established policy categories, including the environmental burden of disease, the effects of water on human health, and agriculture. The indicators serve as a “gauge at a national government scale of how close countries are to established environmental [and health] policy goals,” write the authors.
The EPI draws data from a diverse array of sources, such as the World Health Organization, Food and Agriculture Organization, University of New Hampshire, and World Resources Institute. Users can view visualizations of the compiled data via an interactive map and the data is also available in the form of rankings charts, individual country profiles, and country group comparisons. The interactive map also allows users to isolate performance indicators or policy categories in order to compare an individual country’s performance with global trends. Furthermore, indicators may be scaled to visually reflect a country’s performance in relation to drivers of environmental performance, like gross domestic product, level of corruption, and government effectiveness.
This tool is particularly useful because users can effectively leverage points for policy change by identifying linkages between environmental policy and other issue areas, such as public health or sanitation. The EPI enables policymakers to visually conceptualize problematic regions, optimize investments in environmental protection, and identify best practices.
The index’s greatest weakness is its inability to track changes in performance over time. A pilot project was launched last year that tracks whether a country has progressed or deteriorated in an area of environmental performance, but the authors note that the project has “raised more questions than answers,” particularly concerning data availability and interpretation. Additionally, there are gaps in the data. Although these gaps signify a data quality weakness, they also support the continued calls for increased data collection by governments and other organizations to better inform environmental decision-making. -
Yemen Beyond the Headlines: Losing the Battle to Balance Water Supply and Population Growth
›Part three of the “Yemen Beyond the Headlines: Population, Health, Natural Resources, and Institutions” event, held at the Wilson Center on May 18.
Overlooked in most news coverage of Yemen’s crisis is the country’s struggle to manage its limited natural resources – particularly its rapidly depleting groundwater – in the face of soaring population growth. At the recent Wilson Center event, “Yemen: Beyond the Headlines,” Yemen’s ambassador to Germany, Mohammed Al-Eryani, and Daniel Egel of the RAND Corporation outlined Yemen’s shaky prospects for economic development without more sustainable agricultural practices and more efficient water management. [Video Below]
With a population of more than 24 million and a total fertility rate (TFR) of 5.5 – nearly double the average TFR for the region – Yemen’s population is projected to grow to 36.7 million by 2025 and jump further to 61.6 million by mid-century, according to the latest UN projections. While those figures may not seem large by global standards, given Yemen’s already limited stocks of arable land and groundwater, the country’s rapid rate of growth may quickly outpace its resources.
“Already in a Crisis”: The Groundwater Deficit
Yemen’s per capita water supply is falling fast in the face of booming population growth and agricultural consumption, said Al-Eryani, a water engineer who founded Yemen’s Ministry of Water and the Environment. While the commonly accepted threshold for water scarcity is 1700 cubic meters or less per capita, Yemen’s per capita renewable water availability is now in the neighborhood of 120 cubic meters, he said.
Meanwhile, water scarcity has been exacerbated by erratic precipitation that has hit rainfall-dependent farmers especially hard. In a country with no real rivers or perennial streams, rainfall harvesting has long enabled agricultural production, as evidenced by the country’s many intricately terraced hillsides – “the food baskets of Yemen,” said Al-Eryani.
Yemenis have coped with shifting precipitation patterns by drawing more groundwater for irrigation and other domestic uses. While drilling wells has provided some short-term relief, the practice is unsustainable in the long term, creating a “water deficit,” Al-Eryani said, that continues to grow each year.
In the populous Sanaa basin, home to the Yemeni capital, consumption outweighs the aquifer’s natural rate of recharge by a factor of five to one and groundwater levels have been plummeting at six meters per year, he said. With only minimal government regulation of drilling, the country’s groundwater situation is poised to worsen, one of the reasons Al-Eryani declared his country is “already in a crisis.”
Stalled Economic Development
Yemen’s stalled economic development is particularly pronounced outside of urban areas, “where the resources are,” said Daniel Egel, citing the country’s failure to build modern transportation infrastructure and develop other economic activities besides farming. He called for the international development community to focus on creating jobs in rural areas, particularly by increasing the financing available for non-agricultural businesses and by improving secondary roads. In addition, he warned development actors to be aware of how gender inequality and local social structures, such as tribes, affect development efforts.
Given the country’s dependence on agriculture, water scarcity poses a threat to Yemen’s food security and its economic development. Three out of every four Yemeni villages depend on rainfall for irrigation, Egel said, making them highly vulnerable to unexpected climate change-induced shifts in precipitation patterns. Water scarcity also weakens the financial stability of Yemeni households, with the cost of water “accounting for about 10 percent of income during the dry season,” he said.
Averting a “Domino Effect”
Al-Eryani asserted that water management policies will “have to be designed in piecemeal fashion,” as no one single action will avert a catastrophe. He suggested a number of steps to alleviate the country’s growing water crunch, including:- Focus on the rural population, which makes up 70 percent of the population, has the highest fertility rates, and are the most reliant on agriculture;
- Move development efforts outside of Sanaa to other regions of the country;
- Increase investment in desalination technology for coastal areas;
- Increase water conservation in the agricultural sector; and,
- Exploit fossil groundwater aquifers in Yemen’s sparsely populated eastern reaches.
“The battle to strike a sustainable balance between population growth and sustainable water supplies was lost many years ago,” Al-Eryani said. “But maybe we can still win the war if we can undertake some of these measures.”

Watch: Janani Vivekananda on Climate Change and Stability in Fragile States
›At International Alert, the starting point for thinking about how climate change affects stability is recognizing that climate change will interact with and amplify existing social, economic, and political stressors in fragile communities, said Janani Vivekananda in this interview with the ECSP.
“Rather than climate change being this single, direct causal factor which will spark conflict at the national level,” Vivekananda said, these stressors “will shift the tipping point at which conflict might ignite.” In places that are already weakened by instability and conflict, climate change will simply be an additional challenge.
To address this additional challenge, Vivekananda said two things must be understood about the effects of climate change on fragile states: 1) Environmental, social, economic, and political stressors will be most evident at the household and community level; and 2) Those stressors are interrelated.
“You can’t address one of these things in isolation from the others. You have to understand how they all interact together to be able to respond appropriately,” she said. “We can’t think about food security, for example, without thinking about land degradation.” In addition, responses need to be relevant to their context, and that context “can only be understood through very sub-national, context-specific evidence.” Vivekanada explained that this kind of evidence can only come from a “bottom-up” approach, which should be coordinated as part of a broader effort.
For more on the connections between climate change and stability, see The New Security Beat’s summary of “Connections Between Climate and Stability: Lessons From Asia and Africa,” with Janani Vivekanada, Jeffrey Stark of the Foundation for Environmental Security and Sustainability, and Cynthia Brady of USAID speaking at the Woodrow Wilson Center on May 10.
