Zo Zatovonirina, PHE Champion
Improving Human Health and Conservation in Madagascar’s Forest Communities
›This PHE Champion profile was produced by the BALANCED Project.
Madagascar is one of the world’s most unique ecosystems, with a total of eight plant families, five bird families, and five primate families that live nowhere else on Earth. Madagascar’s tropical forests and marine environments are home to endemic species of flora and fauna, although tragically 15 species are now extinct. At the same time, Madagascar is rich in freshwater resources, yet more than 60 percent of the island’s 19.7 million people do not have access to safe drinking water.Since 2003, Zo Zatovonirina has worked for Conservation International (CI) in Madagascar, and he has seen up-close the challenges of reaching remote forest communities, often requiring one- or two-day hikes over treacherous roads. As coordinator for USAID’s Healthy Families, Healthy Forests Program, Zo worked with two Malagasy nongovernmental organizations (NGOs), MATEZA, and the Association for Health Action and Security, to implement integrated population, health, and environment (PHE) approaches in response to community needs in the Ankeniheny Zahamena forest corridor in eastern Madagascar.
From 2003-2008, CI and partners reached more than 25,000 village residents with PHE messages; increased contraceptive prevalence in target zones from 17 percent in 2005 to 30 percent in 2008; constructed 3,000 latrines; and improved environmental health in all priority sites.
Today, biodiversity in Madagascar is under increased pressure, in light of political instability since 2009 and continued population pressures. Recognizing CI and partner experience and investments in conservation efforts to improve human well-being, USAID Madagascar and World Learning recently awarded a new 15-month grant to CI Madagascar and two Malagasy NGO partners – Voahary Salama and Ny Tanintsika – to implement an integrated PHE project in the southeastern Ambositra Vondrozo forest corridor. All three organizations have implemented PHE projects in Madagascar, and they have established trusting relationships with the people living in these fragile ecosystems.
Madagascar has a rich history of implementing successful PHE projects, and this project represents a new PHE pilot phase in the midst of political uncertainty. According to Zo, PHE approaches remain constant – simultaneously addressing several complex and linked problems such as poverty, child survival, and unsustainable dependency on natural resources. In Zo’s experience, CI’s PHE approach touches on all these aspects and delivers a pragmatic, integrated package of interventions designed to increase community capacity to better manage their health and environment. Utilizing PHE approaches, CI, Voahary Salama, and Ny Tanintsika will strive to reach communities for the first time ever with family planning, water, sanitation, and hygiene services while helping them conserve their biological heritage.

Population, Health, and Environment Approaches in Tanzania
›“Quality of life, human health, food security, and biodiversity are all connected,” said Elin Torell, research associate for the BALANCED Project and the University of Rhode Island Coastal Resource Center. Torell was joined at the Wilson Center on July 19 by Patrick Kajubili from the Tanzania Coastal Management Partnership, and Alice Macharia, director of the East Africa Program at the Jane Goodall Institute to discuss the importance of integrated population, health, and environment (PHE) initiatives that work to simultaneously improve health and livelihoods, manage natural resources, and conserve ecosystems in Tanzania.
Building Resilient Coastal Communities
The Coastal Resources Center’s work in Tanzania’s Saadani National Park provides an example of an integrated PHE approach that sustains the flows of environmental goods and services, maintains biological diversity, and empowers and improves the wellbeing of local residents, said Torell. Since 1996, the CRC has focused on protecting sea turtles, promoting energy-saving stoves, and tracking elephants, while at the same time improving livelihoods through savings and credit associations, eco-tourism, and beekeeping.
“Adding family planning makes a whole lot of sense,” said Torell. There is a high unmet need for family planning in Tanzania and the population is growing rapidly with an average number of 5.6 children per woman. Family planning not only helps families limit and space births but indirectly works to improve food security and human health, reduce demand for scarce natural resources, and empower women, she said.
“Integration is key,” concluded Torell: A coordinated and synergistic approach that meets the varied needs of local communities will be more effective and sustainable than if interventions were delivered independently.
Effective Integration in the Field
“Conceptual linking is not enough,” said Kajubili. “Integration also needs to happen at the organizational and field levels.”
On the ground, the Tanzania Coastal Management Partnership integrates family planning education and services into conservation work, said Kajubili. Peer educators deliver information about family planning, health, and coastal resources management; and community-based distributors deliver family planning services and supplies.
“Now people easily access reproductive health services,” said Kajubili. To date, the program has increased referrals to health centers, promoted contraceptive use, and reduced the distance that women need to travel to receive family planning services.
“Integration makes sense and cents,” said Kajubili. By combining resources, health and natural resource management organizations can potentially reach a broader population while sharing costs.
But “reinforcing the linkages between PHE of course takes time and education,” said Kajubili, highlighting a major challenge to implementing integrated approaches. “Advocacy is needed to overcome cultural and institutional barriers.”
“What About Our Needs?”
“Socio-economic development; family planning and AIDS education; sustainable forestry and agriculture practices; and water and sanitation all underpin and support sustainable natural resource management,” said Macharia.
The Lake Tanganyika Catchment Reforestation and Education Project (TACARE) led by the Jane Goodall Institute was initiated in 1994 to arrest the rapid degradation of land through tree planting and forest degradation, said Macharia. “But at some point, the communities raised the question: What about our own needs?” she said.
Community members prioritized the need for health services, education, clean water, and financial capital. But environmental degradation was not seen as a major issue, suggesting a need for a more integrated approach to TACARE’s conservation efforts.
“Integrated programs including population, health, and environment activities are cost-efficient and add value to conservation goals,” said Macharia. By responding to the needs of the community, the integrated approach adopted by TACARE has gained more credibility among local people, while a strong focus on building local capacity has helped to ensure sustainability of the program.
While there are many challenges to implementing and maintaining integrated PHE programs, “partnerships at the local, district, and national level are key to making this a success,” concluded Macharia.

Leona D’Agnes on Evaluating PHE Service Delivery in the Philippines
›“By reducing population growth, we are going to have a better chance of sustaining the gains of an environmental conservation project,” said Leona D’Agnes in this interview with ECSP. D’Agnes, a technical advisor to PATH Foundation Philippines, served as lead author on a research article published late last year in Environmental Conservation titled, “Integrated Management of Coastal Resources and Human Health Yields Added Value: A Comparative Study in Palawan (Philippines).” The study provided concrete statistical evidence that integrated development programming incorporating population, health, and the environment (PHE) can be more effective in lowering population growth rates and preserving critical coastal ecosystems than single-sector development interventions.
“What set this research apart from earlier work on integrated programming was the rigorous evaluation design that was applied,” said D’Agnes. “What this design aimed to do is to evaluate the integrated approach itself. Most of the previous evaluations that have been done on integrated programming were impact evaluations — they set out to evaluate the impact of the project.” This most recent research project, on the other hand, sought to evaluate the effectiveness of cross-sectoral interventions based on “whether or not synergies were produced,” said D’Agnes.Although it took her team six years to generate statistically significant findings in Palawan, D’Agnes reports that the synergies of PATH Foundation Philippines’ PHE intervention took the form of reduced income poverty, a decreased average number of children born to women of reproductive age, and the preservation of coastal resources, which helped bolster the region’s food security.
Going forward, D’Agnes said, an integrated approach to environmental conservation should also prove appealing because of its cost effectiveness. “This has huge implications for local governments in the Philippines, where they are struggling to meet the basic needs of their constituents in the face of very small internal revenue allotments that they get from the central government,” she said. “They can really pick up on this example to see that at the local level, if somehow they can do this integrated service delivery that was done in the Integrated Population and Coastal Resource Management (IPOPCORM) model, that they’ll be able to achieve the objectives of both their conservation and their health programs in a much more cost-effective way, and, in the process, generate some other [positive] outcomes that perhaps they didn’t anticipate.”
D’Agnes expects the study’s results will prompt a fresh look at cross-sectoral PHE programming. “I hope that this evidence from this study will help to change the thinking in the conservation community about integrated approaches to conservation and development,” she said.

In FOCUS: To Live With the Sea: Reproductive Health Care and Marine Conservation in Madagascar
›July 12, 2011 // By Wilson Center StaffDownload FOCUS Issue 23: “To Live With the Sea: Reproductive Health Care and Marine Conservation in Madagascar,” from the Wilson Center.
Christine does not know how old she is. She has 16 children and lives on a remote island off the southwestern coast of Madagascar. She and her children, like other members of the Vezo ethnic group, depend entirely on the ocean for their survival. Her husband, a fisherman, struggles to catch enough to feed his family.
In this isolated area, most girls have their first child before the age of 18, and families with 10 children or more are commonplace. But since the marine conservation NGO Blue Ventures launched a family planning program in 2007, couples and women like Christine are able to make their own reproductive health choices.
Blue Ventures’ Vik Mohan, Rebecca Hill, and Alasdair Harris argue that their integrated approach, which combines reproductive health care and education with conservation and alternative livelihoods, offers these communities – and the marine environment on which they depend – the best possible chances of survival. -

A Death Foretold
›June 23, 2011 // By Wilson Center StaffThe original version of this article, by Scott Wallace, appeared on National Geographic News Watch.
Late last month the Brazilian Congress passed a bill that if it becomes law would ease restrictions on rain-forest clearing and make it easier than ever to mow down the Amazon. That same day, 800 miles north of the parliamentary chamber in Brasilia, assailants ambushed and killed a married couple whose opposition to environmental crimes had placed them in the crosshairs of those who most stand to gain from the new legislation.
It’s a nauseatingly familiar story. Over the past 20 years, there have been more than 1,200 murders related to land conflict in Brazil’s Amazon region. Most of the victims, like the married activists Zé Claudio Ribeiro and Maria do Espírito Santo, were defenders of the rain forest – people seeking sustainable alternatives to the plunder-for-profit schemes that characterize much of what passes for “development” in the Amazon.
The state of Pará – where Zé Claudio and Maria were ambushed on their motorbike as they crossed a rickety bridge – holds an especially notorious reputation for environmental destruction and organized violence. Pará is the bloodiest state in Brazil, accounting for nearly half of all land-related deaths in recent decades. It sprawls across an area larger than the states of Texas, Oklahoma, and New Mexico combined. Picture a tropical version of the Wild West, stripped of the romance, where loggers and ranchers muscle their way onto public land as though they own the place and impose a law of the jungle with their hired thugs. Those who have the nerve to protest soon find themselves the targets of escalating threats. If they persist, they find themselves staring down the gun barrels of those come to make good on the threats.

Food Security in Kenya’s Yala Swamp
›June 21, 2011 // By Wilson Center StaffThe original version of this article, by Tim Siegenbeek van Heukelom, appeared on State-of-Affairs.
In West Kenya on the Northeastern shore of Lake Victoria, the Yala swamp wetland is one of Kenya’s biodiversity hotspots. The Yala swamp also supports several communities that utilize the wetland’s natural resources to support their families and secure their livelihoods. Even more, many people recognize the swamp’s extraordinary potential as agricultural land to significantly boost Kenya’s food security. These are three widely diverse interests, which may seem to be difficult to reconcile. Yet, with proper management, sufficient investment and effective communication, a differentiated utilization of the Yala swamp can be realized through a system of multiple land use. This will be a difficult but certainly not unrealistic objective.
A Brief History
The most recent development of the Yala swamp was undertaken by Dominion Farms, a subsidiary of a privately held company from the United States investing in agricultural development. The reclamation and development of the swamp, however, is far from a new phenomenon.
The intention of the Kenyan government to transform parts of the Yala swamp into agricultural land for food production goes back as far as the early 1970s. Around that time, the Ministry of Foreign Affairs of the Netherlands was consulted extensively by the Kenyan government for technical assistance on reclamation of the swamp and the feasibility of agricultural production.
Throughout the 1980s numerous reports were commissioned by the Kenyan Ministry for Energy and Regional Development and the Lake Basin Development Authority to the Dutch Ministry of Foreign Affairs. Reports like the “Yala Integrated Development Plan” and the “Yala Swamp Reclamation and Development Project” focused in depth on the potential of the development of the swamp and made recommendations on practical matters, such as drainage and irrigation, soil analysis, agriculture, marketing, environmental aspects, employment opportunities, human settlement, management, and financial planning.
As a result, small-scale reclamation and development of the swamp land was undertaken throughout the 1980s and 1990s under the supervision of the Lake Basin Development Authority. The development of the swamp was partially successful, yet its scale was small and financial benefits were too marginal. Major investment was therefore required to extend the scale of the project.
Then, in 2003, an American investor expressed interest to make significant long-term investments into bringing parts of the swamp into agricultural production. Subsequently, a lease for 45 years was negotiated between Dominion Farms and the Siaya and Bondo County Councils to bring into agricultural production some 7,000 hectares of the Yala swamp. The whole Yala swamp wetland covers 17,500 hectares, which means that Dominion Farms is allowed to reclaim and develop roughly 40 percent of the swamp.
Protracted Conflict
Since the early days of the arrival of the foreign investor in 2004, there has been lingering tension and occasional flares of conflict between the communities surrounding the project site, third parties (i.e. government officials, politicians, NGOs, CBOs, environmentalists), and the investor.
The most commonly touted complaint is that Dominion Farms “grabbed” the communities’ land. While it is hard to trace back the exact procedures and individuals that were involved, there are clear contracts with the Siaya and Bondo County Councils that substantiate the transfer of land-use to Dominion Farms for a period of 45 years. Some claim, however, that the negotiation process for the lease was entrenched in bribery and corruption, yet no one has been able to show this author a single trace of evidence to substantiate these accusations. Similarly, there are complaints by local residents that they were never consulted in the negotiation process – where they should have been, as they rightly point out that the swamp is community trust land. However, the land is held in trust by the relevant county council for the community. The county council should therefore initiate consultations with the local communities and residents to get their approval to lease the land to third parties. So it appears that some of the resentment over the loss of parts of the swamp should not be directed at the foreign investor but rather target the local county council and their procedures.

Book Launch: ‘Human Population: Its Influence on Biological Diversity’
›Measurements of “human population density and growth can be used to identify changes in the viability of native species, and more directly, in changes in ecological systems or habitat quality,” said Richard Cincotta, consultant at the Environmental Change and Security Program and demographer-in-residence at the Stimson Center, speaking at the book launch of Human Population: Its Influence on Biological Diversity.
Cincotta was joined by coeditor L.J. Gorenflo, associate professor of landscape architecture at Penn State University, and contributing author Christopher Small, research professor at the Lamont-Doherty Earth Observatory and adjunct professor at Columbia University, to discuss the book’s objectives, its diverse and multidisciplinary contributors, and its policy implications. [Video Below]
Establishing a Handbook for the Field
“Human Population: Its Influence on Biological Diversity establishes a handbook for the field,” said Cincotta. While the scientific volume is specifically geared towards researchers and conservation managers rather than policymakers, “there are a few Washington-type policy messages that are useful,” he added.
Human population affects biological diversity in multiple ways. While population density alone can be strongly indicative of the viability of different populations of native species, human activities and their chemical and energetic byproducts can also have a strong impact, even when human population density is low, said Cincotta.
Conserving Biodiversity in Different Settings
“Planned solutions, based on strategic actions, increasingly are essential,” said Gorenflo, a professor at Penn State University. “The days of letting nature take care itself are probably gone.” Gorenflo presented results from the two chapters he worked on: “Human Demography and Conservation in the Apache Highlands Ecoregion, U.S.-Mexico Borderlands” and “Exploring the Association Between People and Deforestation in Madagascar.”
“Population density seems to be a reasonably good indicator of biodiversity loss,” said Gorenflo. Data from the Apache Highland Ecoregion (a 12 million-hectare area located along the U.S.-Mexico border) indicate that biodiversity tends to drop off at population densities of more than 10 people per square kilometer. Conservation efforts in areas within the ecoregion that are at, or close to, this density threshold will likely encounter challenges to maintaining biodiversity, he said.
Human mobility is a major consideration, said Gorenflo: “Whereas high fertility can create population growth over generations, high mobility can create population growth in a matter of months or years.” In the Apache Highlands, for example, the 40 percent increase in population between 1990 and 2000 was largely caused by migration into U.S. cities in the region.
In Madagascar, Gorenflo and colleagues examined whether population growth and poverty were systematically driving deforestation and loss of biodiversity. Using data from the 1990s, they found that higher population density only slightly raises rates of deforestation and large increases in income only modestly decrease deforestation.
Not surprisingly, they found that the likelihood of deforestation decreased dramatically in protected areas. In addition, proximity to roads or footpaths was associated with significantly higher rates of deforestation. “Roads, footpaths, and protected areas are all policy decisions,” Gorenflo pointed out. “So when bilateral or multilateral organizations decide to invest in development in a place like Madagascar, they can look at these sorts of investments as being important.”
While there are some similarities to be drawn between regions’ experience with population and biodiversity, said Gorenflo, “every locality likely has a slightly different story; you need to do context-specific studies to get a real handle on what is going on.”
The Human Habitat
In his chapter, “The Human Habitat,” Christopher Small of the Lamont-Doherty Earth Observatory said his goal was “to set the stage for some of the more detailed studies by taking a look at the global distribution of human population.”
Using census data and satellite-derived maps of night lights to serve as a “proxy for development,” Small found that “people are everywhere, but they are not evenly distributed.”
At least half the world’s population lives on less than three percent of the inhabitable land, and most people live at densities between 100 and 1000 people per square kilometer. At both local and global scales, population density and city size are dominated by extremes: There are large numbers of small groups of people, and small numbers of large groups of people, he said.
“The environments where people live are more strongly correlated with features of the landscape than they are with climatic parameters,” said Small. While humans have effectively adapted to a range of climates, the majority of people tend to cluster close to rivers, at low elevations, and close to coastlines. Although it was once thought that three-quarters of the world’s population lived in coastal regions, Small’s results show that the actual number is close to half of these previous assumptions.
Understanding the spatial and environmental distribution of population and managing population growth may therefore help minimize negative impacts on specific habitats and biomes, said Small.

Population Growth and its Relation to Poverty, the Environment, and Human Rights
›“Population, Poverty, Environment, and Climate Dynamics in the Developing World,” in the Interdisciplinary Environmental Review, by Jason Bremner, David Lopez-Carr, Laurel Suter, and Jason Davis, attempts to illuminate and clarify the complex relationships between environmental degradation, population dynamics, and poverty. Population growth is a key driver for the degradation of ecosystem services which has a direct impact on livelihoods and human well-being, write the authors, especially for the poor. They argue that “population growth itself, however, remains an insufficient explanation of the relationship between population, ecosystems, and poverty.” While the field has a come a long way since its “original Malthusian roots,” they write, the relationships between these dynamics differ greatly depending on the area in question, and much work remains to be done on the less well-studied ecosystems.In “An End to Population Growth: Why Family Planning Is Key to a Sustainable Future” from the Solutions Journal, Robert Engelman reminds us that population projections are not set in stone and that the widespread belief that population has to reach nine billion before leveling off is wrong. Nor is coercive “population control” necessary, he writes: “Population growth rates and average family size worldwide have fallen by roughly half over the past four decades, as modern contraception has become more accessible and popular.” Unfortunately, there remains a large number of people around the world without access to family planning, the majority of whom live in developing countries. Engelman points out that while the number of people of reproductive age has steadily increased in these countries over the last decade, donor support has declined. He argues that research, courage, and creativity are needed to reverse this situation, but in a world where most of all pregnancies were intended, population growth would slow long before reaching nine billion.
