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.

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.

‘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.” -

Interplays Between Demographic and Climatic Changes
›“Impacts of Population Change on Vulnerability and the Capacity to Adapt to Climate Change and Variability: A Typology Based on Lessons from ‘a Hard Country,’” appearing in the journal Population and Environment, is a study of societal resilience by Robert McLeman from the University of Ottawa. Beginning with a literature review of the connections between population growth and greenhouse gas emissions, McLeman then details how demographic changes can negatively affect resilience–the ability of societies to cope and adapt to climate changes. Based on empirical studies of small communities undergoing local climate and demographic changes in eastern Ontario, McLeman finds that simultaneous demographic and climatic change “increased stress on local social networks…critical to climate adaptation.”“Climate Change and Population Migration in Brazil’s Northeast: Scenarios for 2025–2050,” also appearing in the journal Population and Environment, examines “demographic dynamics–particularly migration–driven by changes in the performance of the economy due to climate changes.” The region of study was chosen for its high levels of both population and poverty and its dry climate, “which will be severely impacted by growing temperatures.” The study concludes that predicted climate change impacts on agriculture are potential push migration factors and offers policy and planning recommendations to reduce migrant vulnerabilities.
Both articles are part of Population and Environment‘s special issue on “Climate Change: Understanding Anthropogenic Contributions and Responses.” -
Coffee and Contraception: Combining Agribusiness and Community Health Projects in Rwanda
›“Population pressures and diminishing land holdings – due to high fertility rates, war and genocide, and subsequent migration – have caused a rapid decrease in the forested and protected areas and increased soil infertility and food insecurity” in Rwanda, USAID’s Irene Kitzantides told a Wilson Center audience.
Kitzantides, a population, health, and environment advisor and global health fellow, said “the population is projected to reach over 14 million by 2025” – nearly one-third more than today, due to the country’s high fertility rate of nearly 5.5 children per women–which could continue to negatively impact forests and food supplies.
In response to these challenges, USAID supported the Sustaining Partnerships to Enhance Rural Enterprise and Agribusiness Development (SPREAD) Project. SPREAD uses an integrated population-health-environment (PHE) approach to develop the coffee agribusiness and bring family planning, HIV/AIDS, and reproductive health services to coffee workers.
Combining income generation with health services was thought an effective way to “fulfill the overall SPREAD goal of improving lives and livelihoods,” said Kitzantides.
A SPREADing Mandate: Integrating Health and Agribusiness
SPREAD follows USAID’s PEARL I and II Projects, which focused exclusively on agricultural development. Coffee is still at the center of SPREAD’s activities, with $5 million of the project’s $6 million USAID budget earmarked for agricultural development.
However, a broader mandate to include health services emerged after recognition that greater income alone does not ensure greater quality of life. The additional health funding leverages SPREAD’s already established relationships with farming cooperatives to bring health services to traditionally underserved rural communities.
“We really tried to build on the existing assets of the cooperative,” said Kitzantides. “We also really tried to complement local and national public health policy and partners.”
The integration of health with agricultural goals, and the use of already established in-country health programs, has made SPREAD extremely cost-effective, with HIV/AIDS prevention education costing less than $2 per person.
Examples of SPREAD’s integrated work include:Combined health and agricultural lessons: Kitzantides and her colleagues trained nearly 400 animateurs de café, cooperative employees running the agricultural education programs, to incorporate public health objectives into their activities. Combining health and agricultural education into one session takes advantage of workers already trained during previous USAID programs. The combination also attracts more male participants, who traditionally shunned HIV/AIDS, family planning, and reproductive health campaigns and services.
Radio programming: SPREAD worked with the agricultural radio program Imbere Heza (“Bright Future”) to incorporate health messaging at the end of each program.
- Mobile clinics: SPREAD works with cooperatives and local health centers to bring convenient services to farmers when they gather at sales or processing stations during harvests.
Community theater: SPREAD hires local theater groups to perform skits on health. The farming communities “really love community theater and always ask for it,” said Kitzantides.
In its relatively short existence, SPREAD’s health activities have reached over 120,000 people with HIV/AIDS prevention messages; nearly 90,000 with messages discussing family planning/reproductive health; and almost 40,000 about maternal and child health. The project counts 347 women as new users of family planning services.
Lessons learned – which will be examined in more detail in an upcoming issue of Focus – include the importance of using community-based approaches to overcome perceived social barriers; the advantages of integrating cross-cutting activities at the outset of a program; and the need for strong monitoring and evaluation systems to measure the effort’s outcomes.Jason Bremner of the Population Research Bureau said PHE projects such as SPREAD go “beyond what the health sector itself can do and find new ways of reaching underserved remote populations.” He presented a soon-to-be-released PRB map plotting the location of more than 40 PHE projects in Africa.
The success of SPREAD and similar projects demonstrates the potential for PHE approaches to bring reproductive health and family planning services to rural areas, Bremner noted, but there is still much work to be done to scale up this integrated approach – and to document its successes.
Sustaining SPREAD
Kitzantides said it took several years to integrate health activities with the already established agricultural programs. Since USAID funding for the program is scheduled to end in 2011, she is uncertain that the time remaining will be enough for SPREAD’s health partners to develop the logistical and financial capacities to become self-sustaining. But SPREAD has changed attitudes and beliefs, two key objectives that do not require sustained funding.
“We used to talk about growing coffee, making money, buying material things like bikes – not about problems like malaria, HIV/AIDS, etc.,” said one SPREAD agricultural business manager during the program’s evaluation. “Someone could have 5 million Rwandan francs in the house but could suffer from malaria where medicine costs 500 Rwandan francs, due to ignorance. You have to teach people about production, you have to also think of their health to improve their lives.”
