“Population, Health and Human Settlements” is the second chapter in the Rwandan government’s Rwanda State of Environment and Outlook. The chapter highlights the Rwandan government’s recognition of the interconnections between population, health, and environment, noting that population “can influence the state of the environment” and pose strains “on available public infrastructure, limited land, and natural resources.” The chapter examines Rwanda’s population growth and distribution, the state of “environmental health” in rural and urban areas, and health indicators relating to child and maternal health and HIV/AIDS. It goes on to describe government strategies to “improve settlements and human welfare.” “As population pressure is one of the key drivers of environmental degradation and poverty,” the chapter’s authors write, “the implementation of the population policy, especially aspects that address high fertility rates, gender and reproductive health, migration and human settlements” is increasingly important.

The WWF and Equilibrium Research released a report on the interplay between the environment and human health. Vital Sites: The Contribution of Protected Areas to Human Health documents the environmental-human health connection, provides case studies from both the developed and developing worlds, and offers recommendations to enhance the health outcomes that can be gained from environmental good governance. “[P]rotected areas are not a luxury but are key sites to protect not only biodiversity, but also ecosystem services and our wider well-being,” the World Bank’s Kathy MacKinnon writes in the foreword.

Gorillas could disappear from the Congo basin in the next 10-15 years, according to a new report issued by the United Nations and Interpol. The Last Stand of the Gorilla – Environmental Crime and Conflict in the Congo Basin places responsibility for the decline of gorilla populations in the Democratic Republic of the Congo and its surrounding region squarely on the shoulders of resource-hungry militants, who poach gorilla bushmeat to feed hungry soldiers and mine workers and sell in local markets. Militants extract timber, charcoal, diamonds, and other resources to raise funds for arms, reducing gorilla territory.

Yet another rationale is retaliation against park rangers who attempt to limit their illegal activities within national parks. In the process, park rangers have found themselves, their parks, and their endangered charges targets of militant groups seeking to plunder and traffic goods through protected areas. “In Virunga Park alone, 190 park rangers have been killed in the last 15 years,” notes the report, which is also available in an interactive e-book edition.

Conflict with local communities also frequently leads to the slaughter of the gorillas and loss of their habitats. Displaced people and refugees also compete with gorillas for land. In several cases, gorillas facing shrinking natural domains have satisfied their appetites in banana plantations, and local farmers have struck back.

Strengthening Law Enforcement

Not all, however, is dire. The report finds several success stories stemming out of transboundary law enforcement collaboration and recommends increased training and support for local and international law enforcement groups. “The gorillas are yet another victim of the contempt shown by organized criminal gangs for national and international laws aimed at defending wildlife,” said David Higgins, Interpol’s Environmental Crime Programme Manager. “The law enforcement response must be internationally coordinated, strong, and united, and Interpol is uniquely placed to facilitate this.”

Law enforcement in the Congo Basin faces an uphill battle, in part due to conditions present in peace agreements between guerillas and the Congolese government. Removing vehicle checkpoints from important border crossings was key to the insurgents agreeing to peace. While these agreements reduced violence, they have created a highway for illegal exports. This trade props up the militant groups and undercuts the chances for peace on a regional scale. It is an example of how large remaining quantities of automatic weapons and turns to poaching by ex-militants can render post-conflict environments even more damaging to local wildlife than war itself.

Toward Coexistence

In some locations, conflicts between gorillas and local farmers are disappearing with the construction of natural barriers and as local populations realize the potential of ecotourism to generate greater revenue from thriving gorilla populations than collapsing ones. Greater international coordination and local commitment, however, are necessary. Turning threatening competition into beneficial cooperation is possible.

Yesterday Google and the World Bank expanded their data-sharing partnership, first initiated last fall, to include a subset of 54 World Development Indicators and enhanced visualization tools. Users can now interact with data—spanning a range of both environmental and population statistics, from forest coverage area to contraceptive prevalence—using line graphs, bar graphs, maps, and xy-plots. Each option also offers users the ability to follow the data changes over time.

An alternative to Google’s Public Data Explorer is the World Bank’s Data Visualizer. Although limiting data output to an xy-plot, the customization options go beyond those offered by the Public Data Explorer and achieve a good balance between flexibility and ease of use. Table colors and groupings are fully customizable, scales are adjustable, and the chart can be quickly printed or exported as a jpeg.

The journal Nature Geoscience recently published a study comparing the impacts of rural and urban population growth on deforestation. “Deforestation Driven by Urban Population Growth and Agricultural Trade in the Twenty-First Century” finds deforestation is positively correlated with urban population growth and agricultural exports to international markets. In rural areas, however, the link between deforestation and population growth was absent, indicating that urbanization and agricultural export-oriented economies were the primary drivers for forest loss. The study concludes that, rather than focusing on the activities of rural populations, deforestation reduction efforts should target “industrial-scale, export-oriented agricultural production, concomitant with efforts to increase yields in non-forested lands.” (SUBSCRIPTION ONLY)

According to the United Nations, 74 million acres of farmland in the developing world were acquired by foreign governments and investors over the first half of 2009 – an amount equal to half of Europe’s farmland.

A new tool from the Center for Global Development, Forest Monitoring for Action (FORMA) tool, uses satellite data to monitor tropical deforestation on a monthly basis. Using publicly available feeds from NASA and other sources, FORMA detects the spread of deforestation in areas as small as 1 square kilometer. The video above uses FORMA to animate the rapidly growing damage in Indonesia over the last four years.

Some advocates of geoengineering have touted fake, plastic “trees” as a promising technology for absorbing carbon. But other experts are promoting a solution that also filters water, encourages rainfall, prevents erosion and desertification, offers economic opportunities, and provides a vital source of food for a growing global population: real trees.
