Blue Ventures’ Integrated PHE Initiative in Madagascar
›In the small coastal village of Andavadoaka, Madagascar, the village elders offer a bottle of rum and two cigarettes to their ancestors before the men and their sons launch their wooden dugout canoes into the sea. Leaning over the side, their masked faces scour the water for their prey.
Meanwhile, the women – with babies on back and spears in hand – set out on foot into the shallow waters. One probes a small hole with her spear, and a tentacle reaches out to grapple with it. After careful coaxing, she pulls out an octopus, kills it, and adds it to her collection, which she tows on a string behind her.
In total, more than 1,850 pounds of octopus are collected on the opening day of the octopus harvest, a seasonal occurrence in Velondriake, the Indian Ocean’s first locally managed marine area.
Velondriake, which means “to live with the sea,” stretches along more than 40 km of southwestern Madagascar’s coast. The region encompasses 25 villages and is home to more than 8,000 people of the Vezo ethnic group, who are almost entirely dependent on marine resources, such as octopus, fish, and mangrove forests, for subsistence and income. But these resources are quickly disappearing due in large part to over-harvesting.
Blue Ventures Conservation – the London-based NGO I work for – has been working in the area since 2003 to protect the region’s coral reefs and mangroves, as well as their biological diversity, sustainability, and productivity, while also improving the quality of life of the local community.
To this end, Blue Ventures helped the community create a series of coastal marine reserves. Several permanent reserves protect the biodiversity of the coral reefs and mangroves, and help fish populations recover; while nearly 50 temporary reserves have increased the productivity of the octopus and crab fisheries. Octopuses reproduce quickly and juveniles grow at a nearly exponential rate, so a brief harvesting hiatus can lead to significant increases in yield. Increased yields translate to increased profits – something greatly welcomed by the people of this impoverished region.
The people of the region are also reproducing quickly: the average total fertility rate in Velondriake is 6.7 children per woman, according to our data. On average women are only 15 years old when they first conceive. To compound this problem, a majority of the population is under the age of 15 – at or approaching reproductive age. At the current growth rate, the local population will double in only 10 to 15 years. The local food sources, already heavily depleted, barely feed the current population, let alone twice that amount. Without enabling these coastal communities to stabilize their population growth, efforts to improve the state of marine resources and the community’s food security are considerably hindered.
In August 2007, Blue Ventures launched its Population, Health, & Environment (PHE) program as a weekly family planning clinic in Andavadoaka, which provided access to ingestible and injectable birth control options, as well as condoms. The clinic increased the village’s contraceptive prevalence rate (CPR) from 9.4 percent to 36.3 percent, and the Velondriake region’s CPR from 11.0 percent to 15.1 percent, in its first two years. (CPR data for the third year is not yet available, but should be notably higher, especially at the regional level.)
In 2009, Blue Ventures opened two more clinics and began holding quarterly outreach clinics in all Velondriake villages. We started offering long-acting, reversible contraceptive options, including Implanon and IUDs. Most recently, we have implemented a community-based distributor (CBD) program to provide wider access to contraceptives around the region, particularly for villagers that could not easily reach one of the clinic sites. These expansions paid dividends: the number of patients increased almost four-fold between the second and third years, with a cumulative total for all three years of just under 1,700 patients.
Recently, the PHE program began a partnership with the UN Population Fund (UNFPA), becoming the first PHE project to receive support from the UNFPA within Madagascar. The UNFPA funds will allow us to add new regional clinics; launch a behavior change campaign, including a regional theater tour and educational events; and further develop the CBD program.
UNFPA’s support of this initiative represents an important endorsement of Blue Ventures’ integrated approach to the challenges of marine sustainability, food security, reproductive health, and population growth. Funding applications to focus on improving maternal and infant health and to conduct a full health-needs assessment of the Velondriake region are pending.
In taking a population, health, and environment approach, Blue Ventures creates synergies that allow for the more effective achievement of health and conservation outcomes. Through providing family planning and health options – services the community really wants – Blue Ventures generates more support for all of its other initiatives, such as conservation and aquaculture programs.
This integrated multi-pronged approach also helps speed up the move towards a more sustainable future. By empowering and enabling couples to take control of their fertility, couples are able to have the size family they want. The use of family planning helps lower the population growth rate, and lower growth rates decrease pressures on natural resources. Decreased pressures on natural resources lead to healthier ecosystems; healthier ecosystems mean more natural resources available; and more resources lead to healthier families.
Through recognizing this inextricable link between communities, their health, and the environment they live in, Blue Ventures hopes to preserve not just the local coral reefs and mangroves, but the Vezo seafaring lifestyle. This way, the sons on the boats and the babies on the women’s backs may still have enough octopus and fish to harvest when they take their own children out to sea.

Assessing Our Impact on the World’s Rivers
›In a special “Rivers in Crisis” issue of Nature, the lead article, “Global Threats to Human Water Security and River Biodiversity,” presents damning evidence that manipulation of river systems — through the construction of canals, levees, hydroelectric projects, and other infrastructure — has caused serious and lasting biological damage to watersheds throughout both the developing and developed worlds. The authors (all 11 of them!) report that key rivers have become shadows of their former selves in terms of the amount of aquatic life they can support. Without drastically improved stewardship of waterways, “we are pushing these river systems toward catastrophe,” warns Peter McIntyre, an article co-author.The human impact on the world’s river systems will be hard to reverse, says Margaret Palmer, author of a second Nature article on freshwater biodiversity loss, “Beyond Infrastructure.” Human-induced changes to watersheds affect local hydrology at a fundamental level, she contends, weakening rivers’ ability to deliver crucial “ecological goods and services” — such as clean water and nutrient-rich sediment loads — that help maintain the health of local environments and the human populations that depend on them. To fully understand the scope of the problem, Palmer says more research is needed to explore the linkages between biodiversity levels and “ecosystem services” that healthy rivers provide. -
The Tenth Parallel: Dispatches From the Fault Line Between Christianity and Islam
›The latitudinal tenth parallel — located 700 miles above the equator — constitutes a “faith-based fault line” between Islam and Christianity, said Eliza Griswold at the launch of her latest book, The Tenth Parallel: Dispatches from the Fault Line Between Christianity and Islam at the Wilson Center on September 16, 2010. The former Wilson Center public policy scholar traveled more than 9,000 miles to six countries along the line. One quarter of the world’s Muslim population lives north of the line, while one-fourth of the world’s Christian population lives south of it.
Religious Conflict and Environmental Peacemaking
The tenth parallel is vulnerable to intense religious conflicts, exacerbated by the imposition of colonial-era national borders. Griswold collected stories from tribal leaders, presidents, and missionaries that reveal subtle linkages between religious conflict, politics, and environmental change. “Every single religious conflict I saw had a worldly trigger, whether land, oil, or water,” she said, because these groups tend to self-identify along lines of religion, “even over any kind of ethnicity.”
In the town of Abiay, Sudan, Griswold described a fight “over who’s going to get that oil, and how they’re going to divide themselves. Religion comes in as an overlay, because the north pushes the people of the south farther south by saying, ‘Guess what? We need that land, and why? Because our Muslim people need that land for their cattle,’ but underneath that land runs a river of oil.”
But in these origins of conflict Griswold finds an avenue to peace: “Environmental challenges seem to work well in areas of religious conflict” as a neutral meeting ground, she said.
For example, in the Nigerian city Kaduna, where Christians and Muslims have clashed violently, two former mortal enemies and self-avowed fundamentalists work together to deprogram the youth they trained to protect their faith through violence. At the Interfaith Reconciliation Center, Pastor James (who lost an arm to a group of Muslims) and Imam Muhammed Nurayn Ashafa use practical aspects of living to encourage interfaith dialogue. During Griswold’s visit, it was fuel-efficient cookstoves, “because that’s one of the things Christians and Muslims fight about…whether land, water, oil.”
Such concrete examples of environmental peacemaking offer future policy options for mitigating conflicts in other areas. “The tenth parallel is one of the most sensitive environmental zones in the world…so do I think it’s replicable? Absolutely,” said Griswold.
The Changing Demographics of Religion
Today, “four out of five of the world’s one billion Muslims don’t live in the Middle East; they live in Africa and they live in Asia. More than half of them live along the tenth parallel, and about half of the world’s two billion Christians also live along the tenth parallel,” sais Griswold.
She explained that the migration of Islam to Africa stopped along the tenth parallel because of the tsetse flies and the devastating sleeping sickness they carried.
Later, colonial-era European missionaries arrived, many with “the express purpose of stopping Islam from winning Africa, from spreading south of the tenth parallel,” she said. For example, Britain’s division of Sudan restricted Muslims to the north and Christians to the south, where missionaries developed and constructed the southern Sudanese state.
“Many of these places are failed states…and religion has come in largely to fill the gaps,” said Griswold. “The world is breaking down on tribal lines and religion is the largest tribe there is, more so than ethnicity, more so than other global markers.”
Based on population projections, Griswold pointed out that “the center of Christianity, in 2050 will be on the tenth parallel…in Muslim Nigeria.”
Historical Echoes
Historically, aid and development work along the tenth parallel “was not a secular enterprise,” Griswold said, since most of the aid workers were Christian missionaries. “So there is a very long history and a very strong association between the West and Christianity in many, many places,” she pointed out.
This history has long affected American foreign policy and perceptions of the United States abroad. According to Griswold, “foreign policy [has] come to reflect the interests of selective groups of Americans.” For that reason, “we really need to call for caution in how we allow ourselves to be represented and in the diversity of voices that get out there,” she advised.
For example, the evangelical preacher Franklin Graham met with Bashir in 2003 to ask for the right to proselytize in northern Sudan. In exchange, Bashir hoped to avoid being added to “the American ‘hit list’ after Afghanistan and Iraq,” reported Griswold. Graham told her that in response he took out a George W. Bush re-election pin and said, “Mr. President, I understand you’ll be talking to my president later today. Why don’t you tell him you’re his first voter here in the Sudan?”
In the same vein, Griswold cautioned against perpetuating American ignorance of Muslim culture:We, especially in America, are extremely aware of this fight over who speaks for God. Because I think, when we see what’s happening on the steps of the Lincoln Memorial or at Ground Zero, we’re looking at a struggle inside of a broader Christian context between Franklin Graham and Barack Obama over who a true Christian is. And Islam becomes the easiest bogeyman. The quickest way to whip up fear in followers is to create a shared enemy.
“The single most important finding of the book,” Griswold concluded, “was that the clashes within religions, the clashes between Christians and Christians, Muslims and Muslims, over who has the right to speak for God, are the most important and most overlooked religious conflicts going on today.”

Rough Waters Ahead: Our Changing Ocean
›From the ocean-themed June issue of Science comes “Sea-Level Rise and Its Impact on Coastal Zones“, by Robert J. Nicholls and Anny Cazenave. While sea-level rise will “almost certainly accelerate through the 21st century and beyond because of global warming,” Nicholls and Cazenave state that its magnitude remains uncertain. Small islands as well as the coasts of Africa, India, Southeast Asia, and China are identified as vulnerable areas because of their “dense populations, low elevations, appreciable rates of subsidence, and/or inadequate adaptive capacity.” Nicholls and Cazenave call for more research and analysis into adaptation, which “remains a major uncertainty.”“Ocean Acidification: Unprecedented, Unsettling,” by Richard A. Kerr, also appears in the June issue of Science. “Humans are caught up in a grand planetary experiment of lowering the ocean’s pH, with a potentially devastating toll on marine life,” begins Kerr, who aims to convince climate change-focused readers to also look at the world’s oceans. Rising pH levels, caused by ocean waters absorbing higher levels of carbon dioxide, are damaging shelled creatures, coral, and the organisms that rely on them for sustenance (which includes people, especially coastal populations dependent on the oceans for protein). An Australian survey recently found that calcification in the Great Barrier Reef had declined 14.2 percent since 1990 – a severe decline that has not been matched in the last 400 years. Kerr claims that “aside from the dinosaur-killing asteroid impact, the world has probably never seen the likes of what’s brewing in today’s oceans.” -
Protect Nature to Protect Us: Biodiversity and Adaptation to Climate Change
›June 17, 2010 // By Dan Asin“We believe that changes in biodiversity, either through local extinction or biological invasions, is the single most important and dramatic problem in contemporary ecology,” reads the mission of the Naeem Lab, led by Professor Shahid Naeem of Columbia University and editor of Biodiversity, Ecosystems Functioning, and Human Wellbeing: An Ecological and Economic Perspective. As Naeem told a group of USAID employees last week, this problem is even more important today, because biodiversity is a key factor in determining the resilience of life–and could be an important ally in the fight against the impacts of climate change.
At the talk, Naeem described an experiment funded by the National Science Foundation that tested the effect of carbon dioxide, nitrogen, and diversity of plant species on rates of plant growth. The scientists found both carbon dioxide and nitrogen exposure to increase plant growth, but the impact of biodiversity to be even greater.
In the monoculture trials, exposure to carbon dioxide, nitrogen, and both increased vegetation growth by by 7 percent, 2 percent, and 17 percent, respectively. When the plot was expanded to include 16 species, however, rates of plant growth jumped to 22, 25, and 36 percent.
Real-World Implications
Naeem’s message aligned with an earlier World Bank report, Biodiversity, Climate Change, and Adaptation, which in 2008 noted that “Climate change is already impacting on ecosystems and livelihoods, but enhanced protection and management of biological resources can mitigate these impacts and contribute to solutions.”
The report, which examines the importance of biodiversity to mitigating and adapting to climate change, cites real-world examples, such an analysis of a forest management project in Madagascar that would cost $97 million but generate $150-180 million in revenue from direct payments for conservation activities, ecotourism, and watershed protection.
Another example focuses on a farmer in South Africa’s Bokkeveld Plateau, who 30 years ago switched from cultivating cereals and pasture crops to nurturing indigenous vegetation. “With the diversity of indigenous plants, McGregor was able to maintain productivity for much longer through the dry summer season,” the report says. Further, he was able to eliminate the need for pesticides and increase the productivity of sheep grazing. The flowering of the natural plants attracted tourists to his farm, generating greater income for both himself and his district, and has since become South Africa’s ninth botanical garden.
Bringing Science to Bear on Policy
Still, Naeem said that although the scientific evidence connecting biodiversity, resilience, and adaptation has long been established, it is in large part failing to affect environmental and development policy. Naeem said scientists have completed their leg of the race but aren’t able to reach the policymakers who need to carry-on the baton. Along the chain connecting research and policy-making the message becomes lost or diluted.
“How do we translate the science?” Naeem asked the USAID practitioners in the audience. The knowledge of biodiversity’s important role in climate adaptation is available, but how can scientists ensure that it impacts policy? Members of the audience cited both Congressional funding mandates and departmental silos as significant barriers to efforts to address the link between biodiversity and adaptation.
One promising avenue could be programs that already work across departmental silos to integrate environment and health initiatives in areas of the world with high biodiversity. These population-health-environment (PHE) programs, which seek to preserve biodiversity while improving community livelihoods and human health, could be effective mechanisms for exploring the contribution of biodiversity to climate adaptation.

Population and Sustainability
›“The MAHB, the Culture Gap, and Some Really Inconvenient Truths,” authored by Paul Ehrlich and appearing in the most recent edition of PLoS Biology, is a call for greater participation in the Millennium Assessment of Human Behavior (MAHB). MAHB was created, he writes, because societies understand the magnitude of environmental challenges, yet often still fail to act. “The urgent need now is clearly not for more natural science…but rather for better understanding of human behaviors and how they can be altered to direct Homo sapiens onto a course toward a sustainable society.” MAHB aims to create an inclusive global discussion of “the human predicament, what people desire, and what goals are possible to achieve in a sustainable society” in the hopes of encouraging a “rapid modification” in human behavior.The BALANCED Project, lead by the Coastal Resource Center at the University of Rhode Island, released its first “BALANCED Newsletter.” To be published biannually, the newsletter highlights recent PHE fieldwork, unpacks aspects of particular PHE projects, and shares best practices in an effort to advance the BALANCED Project’s goal: promoting PHE approaches to safeguard areas of high biodiversity threatened by population pressures. The current edition examines the integration of family planning and reproductive health projects into marine conservation projects in Kenya and Madagascar, a theater-based youth education program in the Philippines, and the combining of family planning services with gorilla conservation work in Uganda. The newsletter also profiles two “PHE Champions,” Gezahegh Guedta Shana of Ethiopia and Ramadhani Zuberi of Tanzania.“Human population growth is perhaps the most significant cause of the complex problems the world faces,” write authors Jason Collodi and Freida M’Cormack in “Population Growth, Environment and Food Security: What Does the Future Hold?,” the first issue of the Institute of Development Studies‘ Horizon series. The impacts of climate change, poverty, and resource scarcity, they write, are not far behind. Collodi and M’Cormack highlight trends in, and projections for, population growth, the environment, and food security, and offer bulleted policy recommendations for each. Offering greater access to family planning; levying global taxes on carbon; introducing selective water pricing; and removing subsidies for first-generation biofuels are each examples of suggestions advanced by the authors to meet the interrelated challenges. -
Philippines’ Bohol Province: Elin Torell Reports on Integrating Population, Health, and Environment
›For 10 years, I have been working on marine conservation in Tanzania with the University of Rhode Island’s Coastal Resources Center. As part of that effort, I’ve helped forge links between HIV/AIDS prevention in vulnerable fishing communities and marine conservation. However, family planning and reproductive health (FP/RH) were relatively new to me. But a recent study tour of an integrated Population, Health, and Environment (PHE) program in the Philippines helped me understand that combining family planning services and marine conservation can help reduce overfishing and improve food security.
Together with developing country representatives from seven African and Asian countries, I spent two weeks in February visiting three PHE learning sites and a marine protected area in Bohol province in the central Philippines, as part of a South-to-South study tour sponsored by the USAID-funded BALANCED Project, for which I work. The tour focused on the activities of the 10-year-old Integrated Population and Coastal Resource Management Initiative (IPOPCORM) project, which is run by PATH Foundation Philippines, Inc. (PFPI).
IPOPCORM has garnered a wealth of lessons learned and best practices to share with PHE newbies like me. Its integrated programs train people to be community-based distributers (CBDs) of contraceptives and PHE peer educators, as well as work with local and regional government officials to build support for family planning as a means to improve food security.
I was most impressed with the ways in which PFPI identifies and cultivates dynamic and motivated local leaders–men, women, and especially youth–to reach out to the members of their community who are highly dependent on marine resources for their survival. My Tanzanian colleagues and I would like to foster the volunteer spirit and “can do” attitudes we experienced through our work in East Africa. (Similar PHE peer educators are successfully working in Ethiopia’s Bale Mountains, as reported by Cassie Gardener in a previous edition of the “Beat on the Ground.”
My favorite part of the tour was a trip to the Verde Island Passage to see PFPI’s efforts in this fragile hotspot. The insights my Tanzanian colleagues and I gained from talking to the field practitioners in the Verde Islands helped us refine our ideas for translating some of the PHE techniques used in the Philippines to the Tanzanian cultural context, including an action plan for strengthening our existing PHE efforts with CBDs and peer educators.
Thanks to the study tour, I now have a better understanding of how to address population pressures in the context of conservation. Overall, my Tanzanian colleagues and I were inspired by the successes we saw firsthand and hope to emulate them to some degree in our own projects.

High Altitude Turbulence: Challenges to the Cordillera del Cóndor of Peru
›In 1998, Peru and Ecuador settled a long-running border dispute in the Cordillera del Cóndor mountain range that had killed and wounded dozens on both sides in 1995. In addition to pledging renewed cooperation on deciding the final placement of the border, the agreement, the Acta Presidencial de Brasilia, committed both sides to establishing extensive ecological protection reserves on both sides of the border: A peace park of sorts was born.
But now, indigenous groups fear that extractive industries in the area could threaten both the biodiversity and the ecological integrity of the forests and streams that they rely upon for their survival. They detail these charges in a new report, Peru: A Chronicle of Deception, and in a new video documentary, “Amazonia for Sale.”
Located on the eastern slopes of the Equatorial Andes, the area is a recognized global biodiversity hotspot with large areas of pristine montane habitat. In 1993-4, Conservation International led a biodiversity assessment trip to the area and identified dozens of species new to science. Their report, The Cordillera del Cóndor Region of Ecuador and Peru: A Biological Assessment, noted the “spectacular” biodiversity of the area, and its key role in the hydrological cycle linking the Andes with the Amazon.
Recognizing the region’s importance, the Acta Presidencial de Brasilia stipulated the need to create and update mechanisms to “lead to economic and social development and strengthen the cultural identity of native populations, as well as aid the conservation of biological biodiversity and the sustainable use of the ecosystems of the common border,” wrote Martin Alcade et al. in the ECSP Report.
Indigenous communities in Peru are accusing the Peruvian government of reneging on those promises by allowing extractive industries extensive access to the region. They charge that the government gave in to gold mining interests who want to reduce the size of the protected area in the Cordillera del Cóndor. They also claim that the Peruvian government is violating promises made to include indigenous peoples in the governance and management of the area.
Carefully managing extractive activities was a key priority for Peru and Ecuador when they negotiated an end to their border dispute. A management plan for the area with strong protection for key biodiversity areas was supposed to ensure everyone’s interests.
However, Peru’s current president, Alan Garcia, has been aggressive in promoting extractive industries in Peru,to the point of inciting significant popular opposition among many indigenous peoples. Less than a year ago, protests over oil exploration in Amazonian lowlands city of Bagua killed and wounded dozens of Peruvians. This violence followed years of social conflict over mining development in a number of communities in Peru’s Andean highlands.
Earlier this decade, Peru made some progress in resolving extractive disputes. But Garcia’s strong promotion of the extractive sector in the face of indigenous opposition, like we currently see in the Cordillera del Cóndor region, suggests years of confrontations to come.
