Commercial road would disrupt world's greatest migration

The Wildlife Conservation Society (WCS) and the Zoological Society of London (ZSL) are requesting that the Government of Tanzania reconsider the proposed construction of a commercial road through the world's best known wildlife sanctuary—Serengeti National Park—and recommend that alternative routes be used that can meet the transportation needs of the region without disrupting the greatest remaining migration of large land animals in the world.

At issue is the proposed Arusha-Musoma highway, slated for construction in 2012. According to the proposed route, the highway would bisect the northern portion of the park and jeopardize the annual migration of wildebeest and zebra, a spectacle comprising nearly two million animals. The Serengeti is a World Heritage Site and is universally regarded as one of world's great natural wonders.

"The Serengeti is the site of one of the last great ungulate migrations left on Earth, the pre-eminent symbol of wild nature for millions of visitors and TV viewers, and a hugely important source of income for the people of Tanzania through ecotourism," said Dr. James Deutsch, Executive Director of the WCS's Africa Program. "To threaten this natural marvel with a road would be a tragedy. We implore the Tanzanian government—known around the world for its commitment to conservation—to reconsider this proposal and explore other options."

"A commercial road would not only result in wildlife collisions and human injuries, but would serve to fragment the landscape and undermine the ecosystem in a variety of ways," said Prof. Jonathan Baillie, Director of Conservation Programmes for ZSL, which partners with WCS in the long-term monitoring and conservation of Serengeti's cheetahs. "To diminish this natural wonder would be a terrible loss for Tanzania and all future generations."

WCS and ZSL are two of numerous organizations—including the Frankfurt Zoological Society (FZS)—in growing opposition to the proposed road.

Supporters of the proposed road point to the need for linkage between the districts of Serengeti and Loliondo and the national road system, as well as a need for increased transport infrastructure between the coast and the hinterland. However it is possible to achieve these objectives without bisecting the Serengeti.

Conservationists predict that building the road through Serengeti National Park would not only result in a catastrophic decrease in numbers of wildebeest, zebra, and other species as a result of the interruption of the migration. It could also potentially cut Kenya's Masaai Mara National Reserve off from the migration, jeopardizing that country's most important tourism destination.

WCS, ZSL, and other conservation groups acknowledge and support Tanzania's need for infrastructure development, specifically to benefit the country's industries and agricultural markets. An alternative southern route, they assert, would better meet these objectives, and provide more benefits for more people while maintaining the integrity of Tanzania's foremost wildlife attraction and the tourism dollars it generates.

"We recognize that there is an obvious need for infrastructure development in Tanzania," said Markus Borner, Africa Program Director for FZS which has worked in the Serengeti since the 1950s. "A far better option than the current proposal is placing a road to the south of the park. Such a road would be both cheaper to construct and would serve a much larger number of people without interrupting the migration and jeopardizing the iconic status of the Serengeti National Park."

Notes for Editors

Measuring some 5,700 square miles in size, Serengeti National Park is characterized by a mix of grasslands and plains, riverine forests, and woodlands. Its most noteworthy attraction is the migration of two species—the white-bearded wildebeest and the plains zebra.
The movements of the herds are driven by the dry and wet seasons, with the vast herds setting out for the perennially wet northern landscape when the south becomes dry.
Access to the Mara River in the north—a critical water source during the dry season—would become severed by the road and cause the wildebeest population to collapse.
The landscape also contains many globally important populations of threatened species—cheetahs, lions, leopards, wild dogs, elephants, rhinos—and is the traditional home of the Maasai, a nomadic cattle-herding people who have co-existed with the region's wildlife for millennia.
The name Serengeti is based on the word Siringitu, which means "the place where the land moves on forever."

The Serengeti National Park itself is part of a larger landscape that includes the Ngorongoro Conservation Area, the Maasai Mara National Reserve in Kenya, and several adjacent game reserves. The area draws more than 90,000 tourists to the region every year.

The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes towards nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth. For further information please visit:

Founded in 1826, the Zoological Society of London (ZSL) is an international scientific, conservation and educational charity: our key role is the conservation of animals and their habitats. The Society runs ZSL London Zoo and ZSL Whipsnade Zoo, carries out scientific research at the Institute of Zoology and is actively involved in field conservation overseas.

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
