Yesterday, in a post on his Dot Earth blog, New York Times science reporter Andrew Revkin called attention to the fact that 2.6 billion people lack access to sanitation facilities—and that includes pit latrines, not just flush toilets. The World Health Organization estimates that inadequate water, sanitation, and hygiene are responsible for 4 percent of all deaths worldwide and 5.7 percent of the total global disease burden (including premature death and years lost to disability caused by disease). Children are the most acutely affected by poor sanitation: 1.5 million children die each year from diseases—primarily diarrhea—caused by inadequate sanitation.

Tomorrow is World Water Day, and in honor of 2008 being the International Year of Sanitation, the United Nations and other organizations will strive to raise people’s awareness of sanitation, combat the taboos against discussing it, and galvanize efforts to halve the number of people without access to sanitation by 2015—a Millennium Development Goal.

The Environmental Change and Security Program’s (ECSP) Navigating Peace Initiative seeks to call attention to the importance of water and sanitation issues. ECSP’s Water Stories Flash website includes a multimedia presentation on dry sanitation in Mexico, while “Low-Cost Sanitation: An Overview of Available Methods,” an article by Alicia Hope Herron in ECSP’s recent report Water Stories: Expanding Opportunities in Small-Scale Water and Sanitation, analyzes the pros and cons of the numerous inexpensive, innovative sanitation technologies currently available.

New research suggests that strengthening local natural resource management (NRM) can also improve governance and reduce the risk of violent conflict. Community involvement in governing natural resources is vital to successful conflict prevention, however. In this ECSP podcast, Masego Madzwamuse of the World Conservation Union’s (IUCN) Region of Southern Africa office describes how IUCN’s Community-Based Natural Resource Management (CBNRM) Support Programme in Botswana helps communities manage their own rangeland, forests, and water. Illustrating NRM-governance-conflict connections in a different part of the world, David Bray of Florida International University recounts his work in two adjacent watersheds in Guerrero, Mexico—one where strong community-led NRM helped prevent conflict, and another where weak community institutions contributed to violent situations.

The Kenyan army launched a major assault on the Sabaot Land Defence Force (SLDF) yesterday, said officials. More than 500 people have been killed in land clashes involving the SLDF over the past year and a half, including 13 last week.

Land clashes lie at the heart of a recent outbreak of violence at the foot of Mount Elgon in western Kenya that left at least a dozen people—including several children—dead. Although President Mwai Kibaki and opposition leader Raila Odinga reached a power-sharing agreement last week, BBC News reports that post-election strife continues to reignite pre-existing conflicts over land and livelihoods in the country. Regions with longstanding violent feuds over land have been hit worst by the latest bloodshed.

According to Bernard Muli, a local police chief, the Sabaot Land Defence Force (SLDF) is responsible for the latest wave of attacks. The SLDF seeks to avenge alleged discrimination against the Soy clan in the government’s Chebyuk Settlement Scheme, which redistributed land in the area. The SLDF is one of the most powerful and best-armed non-state groups in Kenya, according to the International Crisis Group.

Many analysts have noted the links between historical land grievances in Kenya and the violence that followed the country’s multi-party elections in the 1990s. In a recent blog post on the New Security Beat, Colin Kahl notes how this unresolved issue resurfaced again during the latest elections.

Norman Borlaug’s innovative plant breeding techniques—which he used to develop varieties of wheat resistant to stem rust—spawned the Green Revolution and earned him the Nobel Peace Prize in 1970. An article in MIT Technology Review (free registration required) discusses why the Green Revolution did not spread to Africa and which policies and techniques could strengthen African agriculture.

Rwanda, Uganda, and the Democratic Republic of the Congo (DRC) announced an unprecedented joint effort to save the critically endangered mountain gorilla on February 20, 2008. As part of the 10-year Transboundary Strategic Plan, the countries will develop and adhere to a consistent set of conservation policies and laws in Virunga National Park, which overlaps the three countries and is home to more than half of the world’s 700 remaining mountain gorillas.

Nigerian Senator David Dafinone argued yesterday that the Nigerian government should abandon plans to allocate 444.6 billion Nigerian nairas in the 2008 budget to security in the conflict-ravaged Niger Delta. “Dedicating such huge amount to policing the Niger Delta will be counter productive because resentment of the state and the oil companies by the people will continue to deepen,” said Dafinone, who hails from the Delta. “There is urgent need to reorder the political, social and economic development of the Niger Delta,” he continued. “The root cause of the crisis in the region remains the denial of the peoples’ right to land and its content.”

“In Kenya’s highly competitive landscape, land has become the battleground,” argued Kenyan environmentalist and 2004 Nobel Peace Prize laureate Wangari Maathai in a recent op-ed in The Washington Post. Maathai joins a growing group of experts who emphasize that recent violence in Kenya stems not only from ethnic divisions, but also from longstanding tensions over resource allocation. Earlier this year, guest contributor Colin Kahl asserted that the struggles between the Kikuyu, Luo, and Kalenjin tribes are partly based on disparate levels of property ownership.

The media sometimes portray the violence in Kenya as a simple manifestation of ethnic friction, but many commentators note the importance of land distribution and other factors. Maina Kiai, chairman of the Kenya National Commission on Human Rights and a visiting public policy scholar at the Wilson Center, told The New York Times, “You have to understand that these issues are much deeper than ethnic. They are political…they go back to land.” In a similar vein, Oxford University’s David Anderson told Newsweek, “If this violence is really driven by ethnic hatred, why is it that violence breaks out in specific places that are utterly predictable? This violence…is provoked in areas that have a history of violence because of other issues, like land.”

Looking forward, Harvard professor Calestous Juma says that if mediation talks are to be effective, they will have to avoid “the template [of thinking] about Africa in terms of ethnic differences.” Similarly, Maathai emphasizes that “ruling elites must devote time, energy and resources to ensuring…equitable distribution of resources.”
