Ecological Footprint Accounting: Measuring Environmental Supply and Demand
›September 12, 2012 // By Kate Diamond
Twenty-five years have passed since the Brundtland Commission first brought sustainable development to international prominence. Today, the United Nations appears on track to replace the soon-to-expire Millennium Development Goals with “Sustainable Development Goals,” marking the extent to which the international community has embraced the concept. And yet, in spite of its prominence, a specific and measureable definition of sustainability remains lacking.

Resource Revolution: Supplying a Growing World in the Face of Scarcity and Volatility
›August 24, 2012 // By Kate DiamondOver the next two decades, as many as three billion people will join the middle class, even as billions more live without electricity, modern cooking fuel, and safe and reliable access to food and water. Resources are becoming more scarce and more difficult to extract, and combined with environmental factors ranging from climate change to soil erosion, those changes will make meeting middle class demand all the more difficult while leaving the world’s poorest more vulnerable to price shocks and resource shortages. In a recent report, the McKinsey Global Institute concludes that nothing less than a “step change” in how resources are managed will be required if individuals, businesses, and governments are to overcome these trends and pave the way for a more sustainable and equitable future.

Linking Water, Sanitation, and Biodiversity Conservation in Sub-Saharan Africa
›July 25, 2012 // By Kate DiamondWater, poverty, and the environment are “intrinsically connected,” and the development programs targeting them should be as well, writes David Bonnardeaux in Linking Biodiversity Conservation and Water, Sanitation, and Hygiene: Experiences From sub-Saharan Africa, a new Africa Biodiversity Collaborative Group briefing. In a review of 43 programs across sub-Saharan Africa, including four in-depth case studies, Bonnardeaux finds that natural synergies between water, sanitation, and hygiene (WASH) programming and conservation work provide opportunities for greater effectiveness in addressing both.
Integrating WASH and Conservation: A Natural Match
“WASH interventions are generally reliant on natural resources and processes, whether indirectly or directly,” he writes, and “WASH services produce outputs that are potentially detrimental to the environment if not managed properly.” At the same time, poor ecosystem management can “threaten biodiversity and jeopardize the vital services that these ecosystems in turn provide to humanity, in the form of regulation of stream flow, erosion prevention, water filtration, aquifer recharge, carbon sequestration, wildlife habitat, outdoor recreation, and flood abatement.”
Given the connections between the two, WASH and conservation efforts would benefit from programmatic integration, according to Bonnardeaux. To bring the two closer together, he recommends three tools for policymakers and development programmers: integrated river basin management and basin planning; payments for watershed services (also known as payments for environmental services); and population, health, and environment (PHE) programming.
A Whole-of-Basin Perspective
“The causal link between WASH and ecosystem health and integrity is most accentuated when
dealing with freshwater ecosystems,” writes Bonnardeaux.
In Tanzania’s Pangani River Basin, one of his in-depth case studies, a growing reliance on hydropower, urbanization, and increased agricultural demand is altering a valuable ecosystem marked by endemism and iconic landscapes, including Mount Kilimanjaro.
In response, the government and international organizations are partnering through the Pangani River Basin Management Project to developing a greater understanding of the basin’s hydrology and ecosystem, how local populations interact with that ecosystem, and how potential development scenarios could impact the basin in the future. That knowledge, paired with an intensive training program for local water officials, is enabling stronger integrated resource management, which in turn could lay the groundwork for integrating WASH and conservation interventions, writes Bonnardeaux.
Economic incentives – in this case, payments for watershed services – offer another valuable tool for building support for conservation efforts, especially when upstream communities bear a disproportionate burden of safeguarding watersheds.
In South Africa, another case study country, “increased economic development and urbanization have taken its toll on” the country’s wetlands, while unemployment and poverty have remained a persistent problem in slum areas, writes Bonnardeaux. Through the government-run Working for Wetlands program, both the environmental and socioeconomic problems of development are being targeted for improvement. The program hires “the most marginalized from society” to clear wetlands of invasive plants in order to improve its natural filtration capabilities and, in turn, improves the quality of water feeding the burgeoning urban areas.
Although Working for Wetlands, now 17 years old, has been “hugely successful,” Bonnardeaux warns that such economic incentive programs are, more often than not, extremely difficult to carry out effectively. “While there is great potential for this incentive-based conservation approach,” Bonnardeaux notes, “the reality is there are many barriers to its effective implementation.”
Building Long-Term Support for Conservation With Near-Term PHE Successes
Building support for conservation can be a difficult task. The impacts of conservation programming are “often undervalued,” Bonnardeaux writes, in part because results tend to become apparent only over the longer term. By pairing conservation efforts with nearer-term programming, like PHE efforts targeting immediate health needs, development workers can foster the kind of local support that is essential for pursuing long term goals.
The Jane Goodall Institute’s Lake Tanganyika Catchment Reforestation and Education Project (TACARE), in northwest Tanzania, offers a case in point. Established in 1994, TACARE began as a conservation program meant to protect the areas around Gombe National Park, where Goodall first began her chimpanzee research in the 1960s. Local communities, however, were more interested in better health, “with an emphasis on clear water and reduction in water-borne diseases like cholera,” writes Bonnardeaux.
By adopting local health and poverty priorities, he writes, TACARE was able to establish trust and goodwill with the communities it served, which in turn enabled it to pursue longer-term conservation goals aimed at protecting the region’s natural biodiversity.
Bonnardeaux’s work shows that regardless of how policymakers choose to combine WASH and conservation goals, well-implemented integration can yield immense benefits for practitioners, funders, and local communities.
“Linking various sectors such as WASH, forestry, agriculture, population, and community development,” he writes, “can result in cost and effort sharing which in turn can increase the effectiveness of the project including improved conservation and improved livelihoods and health.”

Center for American Progress Takes on Climate Change, Migration, and Why They Matter to U.S. National Security
›July 19, 2012 // By Kayly OberIn early 2012, the Center for American Progress (CAP) released Climate Change, Migration, and Conflict: Addressing Complex Crisis Scenarios in the 21st Century. Although generally in line with climate-migration pieces before it (“It is difficult to fully understand the detailed causes of migration and economic and political instability, but the growing evidence of links between climate change, migration, and conflict raise plenty of reasons for concern”), the report strays from the usual by focusing on U.S. national security interests and four particular sub-regions of concern.
Northwest Africa
The first region examined – and the one perhaps most on the radar of security analysts at the moment – is Northwest Africa. Here the already-tenuous political stability left in the wake of the Arab Spring will most certainly be exacerbated by climate change, authors Michael Werz and Laura Conley write. “Northwest Africa is crisscrossed with climate, migration, and security challenges…rising coastal sea level, desertification, drought, and the numerous other potential effects of climate change have the potential to increase the numbers of migrants.” All of these factors combine to create what Werz and Conley define as an “arc of tension,” that will strengthen organizations that thrive on chaos, like Al Qaeda in the Islamic Maghreb, which has already taken advantage of the regional power vacuum left by Muammar Gaddafi’s ouster.
CAP investigates this arc of tension more fully in a more focused, separate brief on Northwest Africa, drilling down on Nigeria, Niger, Algeria, and Morocco. They find that these countries already grapple with a complex set of issues, including population pressures, drought, land degradation, large-scale migration, and natural resource conflicts. Climate change exacerbates all of these. Particularly worrying is the threat it poses to traditional pastoral and agricultural livelihoods, which could translate into “increasing numbers of disenfranchised youth, who security experts believe are more easily recruited to assist [terrorist groups] in return for money and food.”But environmental pressures and related conflict are not new in these areas, so how do we parse out the slow-onset climate change factors from the usual variety? That question is left unanswered and remains an open – and hotly debated – problem for researchers. The multi-faceted nature of migration, in particular, makes it hard to define the exact causes of movement.
On a larger scale, flagging the environment as the principal reason for migration has its problems, especially under the umbrella of “refugee” status. According to respected migration experts, using the term “refugee” in the case of environmental or climate scenarios is incorrect, since the environment is often simply one “push” factor, while economic opportunities make for a heavier “pull.” Furthermore, applying the term refugee in this case, they say, is misleading and undermines true political refugees.
CAP uses the less polarizing term “climate migrants” in their paper, saying “no universally accepted concepts, much less legal categories, exist to describe or define climate migrants. There is agreement, however, that factors such as drought, flooding, severe weather, and environmental degradation can cause human mobility in large numbers that are certain to increase in the near future.”
South Asia
In a case like Bangladesh and India, the second sub-region to be examined, the international community is preoccupied with rising sea levels, which is considered a more concrete example of climate change affecting migration. Ultimately, as CAP notes, it’s also a security issue:In December 2008 the National Defense University in Washington, D.C., ran an exercise that explored the impact of a flood that sent hundreds of thousands of refugees into neighboring India. The result: the exercise predicted a new wave of migration would touch off religious conflicts, encourage the spread of contagious diseases, and cause vast damage to infrastructure.
While true that India is “not in a position to absorb climate-induced pressures,” as Werz and Conley write, it’s not quite true that “foreign climate migrants” would be necessarily be an immediate problem, as they suggest.
India has a history of taking in Bangladeshi migration, with an estimated 10 to 20 million illegal Bangladeshis currently living in India, according to the Institute for Defence Studies and Analyses, an Indian think tank. Traditionally, Bangladeshis have migrated for a myriad of socioeconomic reasons, but most alluring are land availability and a stronger Indian economy. In any case, Bangladesh-India migration would not be new phenomenon.
The environment has also been a part of the equation, but in the case of large-scale sea level rise, its effect on migration can be a bit more nuanced. As the International Food Policy Research Institute noted in its study “Environmental Migrants: A Myth?,” Bangladeshis often have “risk-sharing and informal lending arrangements” to deal with idiosyncratic shocks, which include flooding. Instead, crop failure actually has the strongest effect on mobility. This suggests that it’s not just sea level rise that observers worried about environmentally-driven migration need to track in Bangladesh, but also drought and rain-induced flooding.
The Andes
The third region, the Andes of South America, also suffers from a slightly myopic security lens. Here, it’s all about melting glaciers and snowcaps. Retreating glaciers would spell disaster for countries which rely heavily on seasonal melt for agriculture and hydroelectric power. Most vulnerable are those with weak governance systems and infrastructure like Peru, Bolivia, Ecuador, and Colombia. For reference, hydropower supplies a whopping 80 percent of Peru’s electricity. However, there are more subtle impacts that could portend bigger trouble for the region.
Regional security experts concede that higher temperatures are already affecting crop production in rural Colombia, harming the ability to consolidate the security gains made by Plan Colombia over the last decade, for example. And a recent report from EUROCLIMA, the European Union’s program on climate change in Latin America, paints an even bleaker picture for agricultural production in the face of desertification and drought:Natural ecosystems, agriculture, water resources, and human health in Latin America have been impacted by unusual extreme weather events reported in the past years. For example, droughts related to El Niño impacts on the flows of the Colombia Andean region basins (particularly in the Cauca river basin), are causing a 30 percent reduction in the mean flow, with a maximum of 80 percent loss in some tributaries. Consequently, soil moisture, and vegetation activity are strongly reduced.
Perhaps more worrying is the impact on the biodiversity in the region. Considering that Latin America represents 16 percent of the world’s surface but 40 percent of its biodiversity this could have serious implications for the biomedical field and others. In a recent Nature study, scientists discovered that in situations where glacial coverage is reduced to the point where it only covers 30 to 50 percent of the drainage basin, several species begin to disappear. They calculated that the entire melting of the glaciers in these areas would result in a huge loss of biodiversity, where between 11 and 38 percent of animal and plant species could go extinct, including many of endemic species that can be found only in these areas.
China and the Third Pole
Finally, China is now in its fourth decade of ever-growing internal migration, some of it driven in recent years by environmental change. Today, across its vast territory, China continues to experience the full spectrum of climate change-related consequences that have the potential to drive migration. CAP finds that the consequences of climate change and continued internal migration in China include “water stress; increased droughts, flooding, or other severe events; increased coastal erosion and saltwater inundation; glacial melt in the Himalayas that could affect hundreds of millions; and shifting agricultural zones” – all of which will affect food supplies and the country’s seemingly relentless pace of development. Still, the most unique factor of migration in China is the power of the central government to be the main “push factor,” as in the case of the Three Gorges Dam.
Agreeing to Agree
Though they might sacrifice some nuance in the regional breakdowns, the core of CAP’s argument for why climate migration matters to U.S. national security is solid. The United States has a “vested interest in helping ensure that areas with weak or absent governance structures – where poverty, environmental degradation, and grievances over central governments and energy production coincide – do not become future recruiting grounds for extremists,” write Werz and Conley. “The possible impacts of climate-related migration in such fragile situations could be destabilizing.” Invest in people rather than just military might; invest in poverty reduction, economic development, and alternative livelihoods.Jon Barnett on migration as adaptation
In the context of climate change, this means accepting that migration is a form of adaptation. As Jon Barnett notes in an interview with ECSP:In some circumstances it might be appropriate to [invest in traditional adaptation projects like] infrastructure and hard options where we’re very certain about the nature of the risk…but in other cases, expanding the range of choices and freedoms and opportunities that people have to deal with climate change in the future is perhaps the better strategy.
This requires higher-level thinking by states to concede that migration will happen and it isn’t necessarily a bad thing. Migration bolsters origin communities through remittances and education and technology sharing. But this thinking has yet to permeate policymaking, with obvious political reasons. Until then, states that are committed to preventing migration are actually cutting off important community responses.
Ultimately, what we consider adaptation and development needs to evolve. By investing in an integrated, multi-sector development approach, we can prevent violent responses to migration at the source rather than relying on reactionary and military solutions. Or, as CAP’s Michael Werz and Laura Conley put it more boldly, “our security can no longer be guaranteed by military strength or economic clout alone, but only by our ability to compel collective action.”

Local Experts Needed to Protect Congo Basin Rainforests Amid Conflict, Development Challenges
›July 13, 2012 // By Wilson Center StaffThe original version of this article, by Ingrid Schulze, appeared on Mongabay.
This summer, the Democratic Republic of Congo (DRC) is expected to approve a new higher education strategy which the country has developed with the World Bank and other international donors. The shape of this educational reform initiative will be critical to Congo’s future in many ways. It could finally offer Congo’s long-suffering people a route into the 21st century. It will also help determine the future of the DRC’s forests.
Nearly half of the Congo Basin’s remaining rainforest is in the DRC – yet the critical role of Congolese experts in forestry, agricultural science, wildlife management and other rural sciences in protecting this forest is not widely recognized.As one Congolese graduate student observed, the DRC has a “void” in agricultural and forestry research. Due to years of war and decades of economic crisis and mismanagement, most of Congo’s colleges and universities are severely underfunded and in disrepair. The country is short of experts who can investigate the ecology and economic potential of Congo’s forests and their biota, and provide an objective basis for setting priorities for protection and use of forest resources. While universities in Kinshasa and Kisangani do have some internationally funded programs to increase the number of biologists and other specialists, the number of graduates is nowhere near what is needed. Foreign scientists and consultants are not a substitute for Congolese experts.
Moreover, competent rural science graduates who can advise local farmers, communities and administrators on forestry, sustainable agriculture, wildlife management, and rural development issues are also desperately needed. The DRC’s national agricultural extension service, which should be integral to this process, has been broken for decades. A 1990 USAID report described it as underfunded, without the means to provide farmers with proven crop varieties and advice on agricultural practices, and tasked more with imposing particular crops on farmers and collecting taxes than helping them. There is little evidence that this has changed significantly since the end of the Congo war in 2003.

Imelda Abano on Environmental Reporting in the Philippines
›“What we are trying to do is to explore more strategies on how to improve environmental reporting in the Philippines – and on how to reach the government and communities as well,” said Imelda Abano, president of the Philippine Network of Environmental Journalists, Inc. (PNEJ) and senior correspondent at Business Mirror, in an interview with ECSP.
With an overwhelmingly coastal population of around 95 million, the 7,150 island archipelago of the Philippines is seen as highly vulnerable to environmental and climate-related threats. One of Albano’s major aims as president of the PNEJ is therefore to “empower local journalists to report more on environmental issues like biodiversity, climate change, disaster, and other environmental challenges in the Philippines,” she said.
Compelling reporting, she said, comes from “try[ing] to understand what the government is trying to say or what researchers or other organizations are trying to say,” and then relating that information back to the people “in the layman’s terms.”
Environmental issues require a lot of context, she said. One of the most important related issues in the Philippines is population growth.
“When you talk about environment issues, it really resonates or links to population issues,” Abano said. Current UN projections estimate that by 2050, the population could balloon to nearly 155 million. “This really affects our jobs, women, culture, and of course the population around the coastal areas.” -
Philippines’ Bohol Island Demonstrates Benefits of Integrated Conservation and Health Development
›In March 2012, I participated in a study tour to the island of Bohol, near the unique Danajon double barrier reef ecosystem – the only one of its kind in the Philippines and one of only three in the Indian and Pacific Oceans. Nowhere is the connection between population dynamics and biodiversity more evident than in the Philippines, one of the most densely-populated countries on the planet, with more than 300 people per square kilometer. Nearly every major species of fish in the region shows signs of overfishing, according to the World Bank.

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.
