The Eye in the Sky: Using Remote Sensing for Population-Environment Research
›May 28, 2010 // By Julien Katchinoff
A recently concluded web seminar hosted by the Population Environment Research Network (PERN) engaged social scientists and Geographic Information Systems (GIS) and remote sensing experts to appraise the role of remote sensing data collection in population and environment research, and identify effective methods for future collaboration.
As the population-environment relationship attracts more study, scholars should consider how remote sensing data will be integrated within existing research needs, as well as how new programs and sensors will help meet future needs. Invited expert Sean Sloan of the University of Melbourne wrote that the potential societal benefits of this research are “immense, albeit largely unrealized. In my view, the principal benefit is that, for the first time, policymakers may draw upon a rich, national-scale empirical basis to develop social/agricultural/economic policy relevant to large-scale environmental issues.”
Cyberseminar participants considered several questions and topics, from determining the most appropriate sensors and instruments for the measurement of population and environment interactions, to addressing the challenges of interdisciplinary research and data interoperability. The discussion also touched on land use and land-cover change, as well how to apply the technology to specific case studies, geographic regions, PE issues, or scalar resolutions.
Demographer Jack Baker of the University of New Mexico raised a tricky issue in his contribution to the discussion of using night-time missions such as Nightsat to calculate population growth and urban sprawl. For his study of remote hunter-gatherers in rural Paraguay, Baker found that “they don’t have electricity so I don’t think they would be captured in satellite views of the night sky. It would be interesting to see how these population estimates I made perform in comparison to an estimate made using night sky imagery …in reality I would like to see lots of these sorts of comparisons before really feeling like I had a grasp on what the strengths and weaknesses of night sky approaches are,” he wrote.
PRB’s Jason Bremner pointed out that despite the high value of remote sensing to understanding human dimensions of environmental change, “the insights remain largely confined to peer-reviewed journals and the academic community. Conservation and development practitioners and policymakers don’t have access to and don’t read the peer-reviewed journals.” In addition, the increasingly technical nature of these methods will require “finding new ways to communicate what we know to those with no technical knowledge of the field,” he said. He urged the participants “to consider what you are doing to overcome the divide between what we know and what others about understand and can use to make decisions.”
Direct dialogue like this between social scientists and remote sensing experts can help establish stronger, more effective ties between two disciplines that would benefit greatly from each other’s support. Such collaboration will be increasingly necessary to address the increasingly complex challenges of population-environment connections.

The Contradictions That Define China
›As a China follower who has visited the country numerous times over the past 40 years, I have an enduring love affair with the “old” China, which prided itself on balancing the harmony of nature with its decision-making. It is tragically ironic that despite this impressive historical and cultural backdrop, current choices have pushed the country’s harmony with nature beyond the tipping point.
The atmosphere in Chengdu, the capital of Sichuan Province in central China, tells a cautionary tale of China’s current emphasis on economic growth at the expense of its citizens’ health. With lower annual sunshine totals than London, Chengdu’s perpetually grey, cloudy horizon graphically illustrates the massive industrial waste and coal-fired pollution that plague this booming city.
In April, global health experts convened in Chengdu at the 5th International Academic Conference on Environmental and Occupational Medicine, which was co-sponsored by the U.S. Centers for Disease Control and Prevention and Chinese CDC offices, to report on the impact of climate change on public health.
Because of its geography, the mountain-encircled basin in which Chengdu sits is the natural point of release for daily deposits of air pollutants and dust blown in from India and other countries to the west. A rapid series of satellite views presented by John Petterson, director of the Sequoia Foundation, brought gasps from conference attendees, as these accumulated industrial wastes were shown concentrating against the massive southern Tibetan mountain range, then turning grey and black as they moved east, before being deposited on Sichuan’s vulnerable (and already heavily polluted) basin.
Environmental risk factors, especially air and water pollution, are a major–and worsening–source of death and illness in China. Air quality in China’s cities is among the worst in the world, and industrial water pollution is a widespread health hazard.
And although air pollution is clearly a complex global problem, individual nation-states continue to approach this dilemma as though it lies between its borders alone.
Luckily, this conference was prefaced by a number of timely scientific articles on China in the Lancet. The predominantly Chinese authors clearly take the critical risks that we expect from the Lancet, which is a defender of accountability and transparency in global health. This issue brings shame to other publications who still consider their “place” to be protecting the conventional politico-economic emphasis on decision-making inherent to most industrialized countries.
At the conference, public health and climate experts openly voiced their frustration at the blatant privileging of economic priorities over the health of unknowing populations. China–the fastest growing economy in world history, with unprecedented growth driven by external “demand” and precipitous acceleration of domestic consumption–has become the poster-child for global ignorance. However, the West is an equal and essential partner, having moved their manufacturing to China for cheap labor, lax environmental regulations, and higher profits.
Dr. Mark Keim, senior advisor for the CDC’s National Center for Environmental Health, presented irrefutable evidence that root structure erosion from advancing saltwater has led to starvation in Polynesia, the first recorded evidence-based outcome measure of climate change’s public health effects.
At Mark’s request, I presented evidence on the worsening health impacts of rapid urbanization, specifically within urban enclaves that expand due to dense population growth before protective public health infrastructures and systems are in place (forthcoming in Prehospital and Disaster Medicine). Currently, the megacities in Asia and Africa–where sanitation is ignored and infectious disease is prevalent–now have the highest infant and under-age five mortality rates in the world.
Today, we face the largest gap in health indices between the haves and have-nots since the alarming days before the Alma-Ata Declaration. This new health data was an uncomfortable surprise to many conference attendees, most of whom were experts in the physical and environmental sciences.
We have become too “vertical” in our research over the past 50 years, and thus we fail to recognize that solutions to problems facing the global community must be trans-disciplinary and multi-sectoral, and serve multiple ministries and decision-makers.
If not undone by human decisions, global climate change and climate-warming greenhouse gases will rapidly intensify. This effort requires the best collaboration between science and the humanities, as well as the harmonious lessons of the “old” China.

Visualizing Human and Natural Resources
›In the policy world, statistics, percentages, and budgets on the order of millions and billions are routinely thrown around. But what do six and a half billion people, 957 tonnes per second, or three trillion dollars really look like?A visualization of London’s natural resources – grass, trees, and water only – by Adam Nieman.
Visual artist Adam Nieman recently received attention from The New York Time’s Dot Earth Blog for his illuminating scale models of hard-to-envision quantities such as the volume of oil being leaked from the Deepwater Horizon wells, global carbon emissions as measured in “UN Building units per second,” and the relatively small amount of air and water on Earth.
Demographers and sustainability experts often warn about the increasingly smaller allotment of natural resources per capita, but few have illustrated that reality at such a human scale as Nieman does.On a global level, Nieman’s work shows the tremendous population density of the world’s “urban island.” Over half of the global population now lives in cities, which is represented by the grey dot, just 616 km across in “Land-Cover Islands.”
Others seeking to improve quantitative visualizations include David McCandless of the site Information Is Beautiful. Among other things, McCandless has tackled the daunting task of accurately comparing spending in an age of trillion dollar budgets, with his “Billion Dollar Gram.”
Another group, the Dutch firm TD Architects, highlights the disparity between global demographics and the distribution of wealth with “Walled World.”
Nieman’s blog examines the confusion that often occurs at the interface between the political and scientific worlds. This confusion is amply demonstrated by debates over contentious issues such as budget priorities, population growth, and climate change.
Politicians often ask that complex problems be distilled into simple bullet points for speeches and policy documents. However, when it comes to problems of such complexity and scale, pictures like these may be worth a thousand bullet points.

Urbanization, Climate Change, and Indigenous Populations: Finding USAID’s Comparative Advantage
›May 26, 2010 // By Kayly Ober“Part of the outflow of migrants from rural areas of many Latin American countries has settled in remote rural areas, pushing the agricultural frontier further into the forest,” writes David López-Carr in a recent article in Population & Environment, “The population, agriculture, and environment nexus in Latin America.” In a May 4 presentation at the LAC Economic Growth and Environment Strategic Planning Workshop in Panama City, Panama, he discussed how to integrate family planning and environmental services in rural Latin America.
Latin America is one of the most highly urbanized continents in the world, with an average of 75 percent of the population living in cities. However, “there are two Latin Americas,” said López-Carr at the workshop, which was sponsored by the Woodrow Wilson Center’s Environmental Change and Security Program and Brazil Institute, as well as the U.S. Agency for International Development. Largely developed countries like Chile, Argentina, and Uruguay are close to 90 percent urbanized, while Guatemala, Ecuador, and Bolivia are about 50 percent. In less urbanized countries, rural-rural migrants in search of agricultural land remain a major driving force behind forest conversion, he said.
Between 1961 and 2001, Central America’s rural population increased by 59 percent, said Lopez-Carr. The increasing density of the rural population had a negative impact on forest reserves: a 15 percent increase in deforestation totaling some 13 million hectares.
“Rural areas of Latin America still have high fertility rates but (unlike much of rural Africa, for example) also have a high unmet demand for contraception, meaning that improved contraceptive availability would likely result in a rapid and cost-effective means to reduce population pressures in priority conservation areas,” he said. Additionally, remote rural areas with high population growth rates tend to be associated with indigenous populations located in close proximity to protected forests.
For example, in Guatemala, communities surrounding Sierra de Lacandon National Park have, since 1990, grown by 10 percent each year, with birthrates averaging eight children per woman. Larger communities and larger households have led to agricultural expansion, which infringes on the park and accelerates deforestation in one of the most biologically diverse biospheres in the world, said López-Carr.
Based on these demographic and environmental trends, López-Carr suggested USAID’s work in the region should focus on rural maternal and child health, and education – especially for girls. Not only does USAID already invest in such programs, but they only cost pennies per capita and could reduce the number of rural poor living in Latin American cities by tens of millions.
Given the strong links between population density and deforestation in Latin America, expanding access to family planning would also be a smart investment in forest conservation and climate mitigation, López-Carr concluded.

Look Beyond Islamabad To Solve Pakistan’s “Other” Threats
›After years of largely being ignored in Washington policy debates, Pakistan’s “other” threats – energy and water shortages, dismal education and healthcare systems, and rampant food insecurity – have finally moved to the front burner.
For several years, the Woodrow Wilson Center’s Asia Program has sought to bring these problems to the attention of the international donor community. Washington’s new determination to engage with Pakistan on its development challenges – as evidenced by President Obama’s signing of the Kerry-Lugar bill and USAID administrator Raj Shah’s comments on aid to Pakistan – are welcome, but long overdue.
The crux of the current debate on aid to Pakistan is how to maximize its effectiveness – that is, how to ensure that the aid gets to its intended recipients and is used for its intended purposes. Washington will not soon forget former Pakistani president Pervez Musharraf’s admission last year that $10 billion in American aid provided to fight the Taliban and al-Qaeda was instead diverted to strengthen Pakistani defenses against archrival India.
What Pakistani institutions will Washington use to channel its aid monies? In recent months, the U.S. government has considered both Pakistani NGOs and government agencies. It is now clear that Washington prefers to work with the latter, concluding that public institutions in Pakistan are better equipped to manage large infusions of capital and are more sustainable than those in civil society.
This conclusion is flawed. Simply putting all its aid eggs in the Pakistani government basket will not improve U.S. aid delivery to Pakistan, as Islamabad is seriously governance-challenged.
Granted, Islamabad is not hopelessly corrupt. It was not in the bottom 20 percent of Transparency International’s 2009 Corruption Perceptions Index (Pakistan ranked 139 out of 180), and enjoyed the highest ranking of any South Asian country in the World Bank’s 2010 Doing Business report.
At the same time, the Pakistani state repeatedly fails to provide basic services to its population – not just in the tribal areas, but also in cities like Karachi, where 30,000 people die each year from consuming unsafe water.
Where basic services are provided, Islamabad favors wealthy, landed, and politically connected interests over those of the most needy – the very people with the most desperate need for international aid. Last year, government authorities established a computerized lottery that was supposed to award thousands of free tractors to randomly selected small farmers across Pakistan. However, among the “winners” were large landowners – including family members of a Pakistani parliamentarian.
Working through Islamabad on aid provision is essential. However, the United States also needs to diversify its aid partners in Pakistan.
For starters, Washington should look within civil society. This rich and vibrant sector is greatly underappreciated in Washington. The Hisaar Foundation, for example, is one of the only organizations in Pakistan focusing on water, food, and livelihood security.
The country’s Islamic charities also play a crucial role. Much of the aid rendered to health facilities and schools in Pakistan comes from Muslim welfare associations. Perhaps the most well-known such charity in Pakistan – the Edhi Foundation – receives tens of millions of dollars each year in unsolicited funds.
Washington should also be targeting venture capital groups. The Acumen Fund is a nonprofit venture fund that seeks to create markets for essential goods and services where they do not exist. The fund has launched an initiative with a Pakistani nonprofit organization to bring water-conserving drip irrigation to 20,000-30,000 Pakistani small farmers in the parched province of Sindh.
Such collaborative investment is a far cry from the opaque, exploitative foreign private investment cropping up in Pakistan these days – particularly in the context of agricultural financing – and deserves a closer look.
With all the talk in Washington about developing a strategic dialogue with Islamabad and ensuring the latter plays a central part in U.S. aid provision to Pakistan, it is easy to forget that Pakistan’s 175 million people have much to offer as well. These ample human resources – and their institutions in civil society – should be embraced and be better integrated into international aid programs.
While Pakistan’s rapidly growing population may be impoverished, it is also tremendously youthful. If the masses can be properly educated and successfully integrated into the labor force, Pakistan could experience a “demographic dividend,” allowing it to defuse what many describe as the country’s population time bomb.
A demographic dividend in Pakistan, the subject of an upcoming Wilson Center conference, has the potential to reduce all of Pakistan’s threats – and to enable the country to move away from its deep, but very necessary, dependence on international aid.

Securing Food in Insecure Areas
›May 25, 2010 // By Dan Asin“Of the 1 billion people who are in food-stressed situations today, a significant proportion live in conflict-ridden countries,” said Raymond Gilpin of the U.S. Institute of Peace at last Thursday’s launch of USAID’s Feed the Future initiative. “Most of them live in fear for their lives, in uncertain environments, and without clear hope for a better tomorrow.”
According to data from the World Food Programme and the UCDP/PRIO Armed Conflict Database, of the countries with moderately to very high hunger rates in 2009, nearly a quarter experienced violent conflict in the previous year, and nearly half in the preceding two decades.
Gilpin said those working toward food security need to develop “conflict-sensitive” approaches, because “a lot of fundamentals that underlie this problem have a lot to do with conflict.” He noted several points, from production to purchasing power, at which conflict enters to disrupt the farm to mouth food cycle:- Production: Be it forced or voluntary, internal or external, conflict often results in displacement. Farmers are not exempt, and when they’re not on their land they cannot produce.
- Delivery: “Food security isn’t always an issue of food availability; it’s an issue of accessibility,” he said. “When violent conflict affects a community or a region…it destroys infrastructure and weakens institutions.”
- Market access: In conflict zones, it is solitary or competing armed contingents, rather than the market’s invisible hand, that control access to supplies. “Groups who usually have the monopoly of force, control livelihoods and food and services,” he said.
- Purchasing power: Conflict disrupts economic activity, degrading both incomes and real wealth. Those remaining in the conflict area suffer from fewer opportunities to conduct business, while those choosing to migrate relinquish their assets. In instances where food is available to purchase, conflict reduces the number of individuals who can afford it.

‘NATO 2020’ Recommendations Avoid “New Security” Challenges
›May 25, 2010 // By Schuyler NullA recently released report, NATO 2020, outlines expert recommendations for the alliance’s new strategic concept. However, while pointing to a nighttime satellite image of the globe at a Wilson Center conference last week, Professor Peter Liotta of Salve Regina University said the report focuses too much on conventional self-defense, when most of the new security challenges of the 21st century will come from areas of the world “where the lights are out.”
In an interview with New Security Beat, Liotta criticized NATO 2020’s emphasis on what he sees as a reactive, rather than a proactive, stance. By ignoring “new security” vulnerabilities such as environmental and demographic challenges, NATO may end up creating more threats for itself down the line, he said.
The report briefly acknowledges that demographic change and environmental degradation represent sources of uncertainty in forecasting global trends. However, neither are included as major threats to the alliance. Instead, the authors say the most probable threats are nuclear or non-nuclear armed ballistic missiles, terror attacks, and cyber intrusion.
Discussions about non-traditional security vulnerabilities often produce contentious and conflicting viewpoints, which makes it easier to ignore them, said Liotta. However, it is important for NATO to realize that security threats – even more conventional ones – do not exist in isolation.
Liotta said the continued focus on NATO’s Article 5, the invocation of collective self-defense, overshadows other important foundations of the alliance. For example, Article 2, which encourages “promoting conditions of stability,” could be invoked to help the alliance address non-traditional security threats.
In his presentation, Liotta, formerly of the U.S. Naval War College, cited mass migration, water scarcity, and low probability, high-risk events, such as rapid sea-level rise from Arctic ice melt, as examples of challenges that NATO should be preparing to meet. He also drew attention to the security challenges of a burgeoning global population, saying that rapid growth and urbanization will produce 600 cities with more than one million people by 2025.
Such extreme events as the 2008 earthquake in Sichuan, China, which killed about 90,000 people and left five million homeless, might be a symptom of the strain our growing population has placed on the Earth’s natural systems, said Liotta. Scientists point out that an earthquake of such magnitude has never been seen in Sichuan and that large construction projects – particularly a large dam and reservoir that lie within 550 yards of the fault line – have likely had a considerable effect on local geology.
In Europe’s current deployment-adverse, difficult fiscal environment, it is perhaps understandable that NATO planners would focus on concrete threats rather than emerging vulnerabilities. But, as Liotta argues, the consequences for ignoring these new security challenges could be no less dire.

21st Century Water
›The Economist published this week For Want of a Drink, its special report on water. The report, a compilation of 11 articles, is a mix of surveys of global management strategies, health impacts, and economic considerations on the one hand, and deeper looks into specific practices in Singapore, India, and China on the other. Most interesting for New Security Beat readers is the article “To the Last Drop: How to Avoid Water Wars.” The article states there have been “no true water wars,” but goes on to question whether the pressures of climate change and population growth could generate different outcomes in the future. While the challenges laid out are manifold, the article concludes that potential for cooperation is equally present. “The secret is to look for benefits and then try to share them. If that is done, water can bring competitors together.”Global Change: Impacts on Water and Food Security, published by IFPRI in collaboration with CGIAR and the Third World Centre for Water Management, is an anthology of focused articles studying “the interplay between globalization, water management, and food security.” While heavily focused on trade and finance, the articles span the spectrum of food and water challenges, from biofuels to the global fish trade. Overall, the book finds that “global change provides more opportunities than challenges,” but taking advantage of globalization’s opportunities demands “comprehensive water and food policy reforms.”
