Elephants’ Fear Of Angry Bees Could Help To Protect Them
At a time when encroaching human development in former wildlife areas has compressed African elephants into ever smaller home ranges and increased levels of human-elephant conflict, a study in Current Biology, suggests that strategically placed beehives
might offer a low-tech elephant deterrent and conservation measure.
The researchers found that a significant majority of African elephants fled immediately after hearing the sound of bees, providing "strong support" for the idea that bees, and perhaps even their buzz alone, might keep elephants at bay. By contrast, the elephants
ignored a control recording of natural white-noise, the authors reported.
"We weren’t surprised that they responded to the threatening sound of disturbed bees, as elephants are intelligent animals that are intimately aware of their surroundings, but we were surprised at how quickly they responded to the sounds by running away,"
said Lucy King of the University of Oxford. "Almost half of our study herds started to move away within 10 seconds of the bee playback." King is also affiliated with Save the Elephants, a Kenya-based organization that aims to secure a future for elephants.
Earlier studies had suggested that elephants prefer to steer clear of bees. For instance, one report showed that elephant damage to acacia trees hosting occupied or empty beehives was significantly less than in trees without hives, the researchers said.
In Zimbabwe, scientists have also seen elephants forging new trails in an effort to avoid beehives.
This behavioral discovery suggests that bees might very well be a valuable addition to the toolbox of elephant deterrents used by farmers and conservation managers across Kenya, King said. She added that such innovative approaches are sorely needed "to avoid
extreme solutions such as shooting problem animals."
"But if we could use bees to reduce elephant crop raiding and tree destruction while at the same time enhancing local income through the sale of honey, this could be a significant and valuable step towards sustainable human-elephant coexistence."

BP Solar Decathlon
The BP Solar Decathlon is a parntered event by BP that has received 20 selected teams by the U.S. Department of Energy to work on this project. The teams are from various colleges and universities from around the world and will work together as teams competing
in a competition to design and build the most energy efficient and aesthetically appealing home powered by solar energy. The event started this month and will be based off of 10 different contests for the overall winner. The homes will ultimately be transported
to the national mall in Washington D.C. for viewing. The whole event is a great opportunity to showcase the young bright minds of new clean and renewable technology.
This is a great idea that could inspire many young and aspiring students for the new wave of alternative energy building methods and the new wave of green tech. For one, this is great PR for BP considering it got a lot of negative attention over its Oil
Refinery in Whiting, Indiana. Now this could a chance for BP to regain its name as a "green" company that truly cares about the environment.
With BP fully supporting this competition, they have designated an on-site reporter to which the reporter and the teams can all post about the challenges of the event. The whole idea is to have the competition get media coverage through the internet as well
as other means.
From an environmentalist point of view, this is a very good move for BP. It shows that it cares about the future of renewable energy and hopefully it convinces the many residents surrounding the Great lakes as well.

There are close to 300 windmills in Kutch area of Gujarat, India. Bird watchers attribute the decline in number of vultures found in this area (from 70 to 15) to the windmills.
Dr Vibhu Prakash, Principal Scientist, Bombay Natural History Society (BNHS) and in charge of the vulture breeding programme says, “Windmills do create problems for birds, especially for large birds like the raptors. They can get sucked into the windmills
and get injured. "

Corporate Revenge?
At the June 2007 annual meeting of the World Wildlife Fund in Bejing, soft drinks giant Coca Cola launched a multi-year partnership with WWF to conserve and protect fresh water resources.
The partnership will focus on " measurably conserving" China’s Yangtze, South East Asia’s Mekong, the Rio Grande/Rio Bravo of South West US and Mexico, the rivers nad streams of the Southern US, the water basins of the Mesoamerican Caribbean Reef, the East
Africa basin of Lake Malawi and Europe’s Danube River.
The $20 million plan skipped India, where Coca -Cola faces protests for allegedly depleting ground water.

For 15 years, Chewang Norphel, a retired civil engineer of Ladakh, has been building "artificial glaciers" to make life a little easier for the hard working but poverty-stricken farmers of Ladakh. He uses a network of pipes to capture and channel precious
snowmelt that would otherwise be wasted. First, water from an existing stream is diverted through iron pipes to a shady area of the valley. From there, the water flows out to a sloping hill at regular intervals along the mountain slope. Small stone embsnkments
impede the flow of water, creating shallow pools. During the winter, as temperatures drop, the water in these pools freezes. Once this cycle has been repeated over many weeks, a thick sheet of ice forms, resembling a glacier.
Norphel says an artificial glacier scores over a natural one in many ways. " It is closer to the village and at a comparatively lower altitude. "
Norphel can be contacted at Tel: 01982-252151

Activists making use of various visual mediums
to create awareness on the project’s impact -Mysore
With Minister for Energy H.D. Revanna asserting that the
Government has no option but to go ahead with its decision to set up
the 1,000-mw coal-fired thermal power plant at Chamalapura to meet the
increasing demand for power in the State, the movement opposing the
decision is being intensified in the urban and rural parts of Mysore.
Chamalapura Ushna Vidyut Sthavara Virodhi Horata Samanvaya Samithi is
making use of various visual mediums to educate farmers and people on
the impact of the project. While environmental organisations such as
the Mysore Amateur Naturalists is engaged in giving power point
presentations on how the project would affect flora and fauna in the
area, besides the life of poor farmers, students of Chamarajendra
Academy of Visual Arts (CAVA) are engaged in preparing publicity
material for the agitation.
A CAVA student has made use of an old building in Kukkarahalli village
to project the impact of the project. "Nirantara", a cultural
organisation, has produced "Baduki-Badukalu Bidi", a mini-documentary,
and is screening it in schools and colleges.
Farmers themselves have arranged the screening of "Matad Matadu
Mallige" which dwells on the plight of flower-growing farmers and how
they succeed in their fight. "Power V/S People: Struggle of
Chamalapura farmers", a documentary produced by Chandrashekar
Ramenahalli, is making waves in Chamalapura and surrounding villages.
As part of the campaign to create awareness among farmers,
Chandrashekar Ramenahalli, who has worked with Medha Patkar in the
Narmada Bachao Andolan, has produced the film with support from the
Chamalapura Anti-Thermal Plant Struggle Committee.
Chandrashekar Ramenahalli, a student of sociology, produced the
documentary in 15 days. The 35-minute documentary, which records the
opinions of farmers and energy experts, also throws light on the lush
green fields in the 12 villages where farmers harvest up to three
crops a year.

One tonne of scrap from discarded computers contains more gold than can be produced from 17 tonne of gold ore. Mumbai alone throws away 19,00 tonne of electronic waste a year, excluding the large e-waste imports from developed nations through its port.
The projected growth for the e-waste generation for India is about 34% year on year.
India already has a few small scale regional recycling programs-’Eparisara’ and’Trishyiraya’ are two such outfits.

"Badabon-er Katha": A tale of the Sundarbans
The Sundarbans, the largest mangrove forest in the world, lies on the Southwestern coastal areas of Bangladesh, forming a seaward fringe of the delta. The Sundarbans is intersected by a complex network of waterways, mudflats and small islands covered with mangrove forests, and presents an excellent example of ongoing ecological processes. The area is known for its wide range of fauna. There are about 334 species of trees and plants and 450 species of animals in this forest - a repository of diversity. Of these, there are 47 species of mammals, 270 species of birds, 45 species of reptiles and 200 species of fish.
A documentary film on the Sundarbans, titled Badabon-er Katha, was premiered on August 18 at National Museum Auditorium. Under the supervision of Manzarehassin Murad, Moynul Huda has directed the documentary. It is a joint venture by Steps Towards Development and Rupantor.
The documentary presents the scenic beauty of the Sundarbans in different seasons, as well as the dependency of humans to the forest for making their living.
Badabon-er Katha begins with images of spectacular beauty of the majestic forest. The documentary features the diverse lifestyles of people living in the Sundarbans, including fishermen, honey collectors and others. Badabon-er Katha also highlights some natural and man-made changes that are fast becoming threats to the existence of the Sundarbans.
Prior to the screening of the film a discussion was held. Professor Abdullah Abu Sayeed, Dr. Ainun Nishat (country representative of The World Conservation Union Bangladesh), Ranjan Karmokar (executive director of Steps Towards Development), Swapan Guha (CEO of Rupantar), filmmaker Manzarehassin Murad and director of Badabon-er Katha, Moynul Huda spoke at the event.
Referring to the Sundarbans as the "only sweet-water mangrove forest in the world", Dr. Ainun Nishat said, "Three points of the forest are listed as a UNESCO World Heritage site. However, this rare heritage site is under threat."
Professor Abdullah Abu Sayeed said, "This documentary will be a record of the Sundarbans, if ever the largest mangrove forest in the world is lost."

Water Hyacinth- economic potential
Water hyacinth is considered a scourge on water bodies. Yet, we only have to look at our neighbours to see the economic potential of this weed.
In Bangladesh, water hyacinth fibre is dried and mixed with jute to create paper and pressed into fibre boards used for partitions.
Yarn made from the fibre is used to make furniture in Bangladesh and baskets in Philippines.
Water hyacinth is used for water purification as it is capable of absorbing heavy metals, organic compounds and pathogens from water.
In Srilanka, water hyacinth is mixed with organic municipal waste, ash and soil, composted and sold to local farmers.
