As gardeners go, Mohammed Bin Abubakar holds a unique position. He has built a forest where once there were only rushed rocks and the unsightly remnants of an old gold mine.

He serves as the reclamation coordinator at Newmont Mining Corporation’s Brong Ahafo Gold Mine in Ghana which started production a few years ago. One Newmont employee, Gloria Dwummah-Adu, says Abubakar has made a beautiful forest out of this mining wasteland and that many should follow this model.

Fondly, she refers to this 75-acre site as “Bin’s garden.” Now birds sing and the shade from the rapidly growing forest is a welcome relief to all who enter these woods.

Abubakar’s reclamation work began some time ago when Australian-based Normandy Mining employed him. When Normandy was sold to Newmont in 2002, he began working for Newmont Ghana Gold, Ltd. This is a green, well-designed forest that invites exploration.

This July the Italian utility Enel unveiled “Archimede”, one of the most important developments in the emerging field of concentrating solar power (CSP). The launch showcases this power plant as the first CSP  plant in the world to use molten salts for heat transfer and storage.

Archimede, a 5 MW plant located in Priolo Gargallo (Sicily). The breakthrough project was co-developed by the utility, Enel, and ENEA, the Italian National Agency for New Technologies, Energy and Sustainable Economic Development. The name, “Archimede,” refers to the rows of huge parabolic mirrors used to capture the sun’s rays, recalling the “burning mirrors” that Archimedes is said to have used to set fire to the Roman ships besieging Syracuse during the Punic War of 212 BC.

TSC Global showcases ‘Roofs for the World’

by grmeyers

TSC Global's hypar roof is located next to the light ril tracks, just south of downtown Denver

Evidence of new buildings featuring an innovative and cost-effective roof can now be seen in a growing number of African nations, including Kenya, Rwanda, Tanzania, Uganda, and Sudan, as part of a Roofs for the World initiative.

This roof is called a Thin Shell Composite Hyperbolic Paraboloid, or TSC Hypar, thus the name, TSC Global, which proclaims  the building methodology using this roof has the potential for revolutionizing roofing and construction in the most impoverished and remote parts of the globe. TSC Global executive director, Brad Wells, says that compared to the corrugated steel roof structures seen everywhere in the developing world, TSC roof construction requires a minimum in cut lumber, demands no power machinery for construction, and leaves almost no carbon footprint. In addition, buildings featuring these roofs are significantly quieter in rain and windstorms, and can be earthquake resistant.

Denver-based TSC Global was created to build, promote and fully develop this construction method, with the belief that there is real potential to dramatically enhance the overall quality and affordability of structures used by millions if not billions of people worldwide. It is now focusing on a potential rebuilding program for Haiti.

Land monitoring

This June the Buckminster Fuller Institute (BFI), founded after the man who made the geodesic dome a household word, awarded its 2010 Buckminster Fuller Challenge prize of $110,000 to African-based Operation Hope for its promising work to transform degraded Zimbabwe grasslands and savannas into a sustainable environment.

The grand prize was well deserved. Here’s why: smart land management work like this can foster water and food security for millions of impoverished people that have suffered for years without such living basics. Read more of this >>

Building roofs-first

On one Denver, Colorado back lot a visitor will encounter an unorthodox-looking roof that just might help meet the housing needs of displaced people worldwide.

The roof, shaped like a hyperbolic paraboloid, was constructed on the ground and then lifted in place by African student builders who wanted to build similar structures in locales like Rwanda and Sudan.

Remarkably strong and weather resistant, this new age shelter contains few structural elements, can be constructed without electrical power, and costs very little money.

George Nez is the developer of this roof system, simply calling it a “hypar roof.” Those familiar with his work – especially those builders in Rwanda and Sudan – fondly refer to this structure as the “Nez roof.” The roof is built using latex-modified concrete that is painted over a mesh backing. A video interview with Mr. Nez can be seen here. Read more of this >>

Mathis Wackernagel of Global Footprint Network, is working with global leaders to help us understand and ultimately align our activities with the basic carrying capacity of the earth.

This 14-minute speech is very much worth seeing and sharing.

Video presented by: Sustainable Life Media:

“We may finally be on the verge of a tipping point wherein mainstream attention to identifying and mitigating a company’s carbon impact will become a core strategic priority for all businesses. But what comes next? The reality is, global warming is just one of the detrimental impacts of unchecked business activity. During this time of seismic shift in awareness of the interconnectedness of things, the opportunity is to take a longer, more systemic view of the many ways our activities impact the world around us.

“By doing so, we will begin to anticipate and respond more quickly to both the needs and the enormous world of possibility in front of us to innovate for a whole, healed world. Be inspired by this thought leader who is working with leaders around the globe to help us all understand and ultimately align our activities with the basic carrying capacity of the earth.

Nature Communications launches

by grmeyers

Nature Communications, the seventeenth publication from Nature Publishing Group was launched this month.. This publication will be different, says the publisher.

Nature Communications differs in being multidisciplinary,” reports the Nature announcement. “It aims not to compete with the established Nature journals, but to publish rigorous and comprehensive papers that represent advances of significance to specialists within each field. In addition, it welcomes submissions in fields that are not represented by a dedicated Nature research journal — for example, developmental biology, plant science, microbiology, ecology and evolution, palaeontology, astronomy and high-energy physics. ”

Using nanotube wires for hybrid fuel cells has renewed promise Source: Nature Communications

One current article discusses hybrid nanotubes as a part of miniaturizing fuel cells for biological applications.

“Now Gao and coworkers show that electrodes made with porous microfibers composed of oriented carbon nanotubes are capable of delivering fast mass transport of the reagents and greatly enhanced currents,” the magazine reports.

Many readers may find much of these works from Nature to be highly academic in nature — even heady sometimes — but such information provides a solid barometer for scientific research and development trends.

Weeds as a cash crop

by grmeyers

Praise for Ghanaian micro business

Weeds rarely are welcome in the garden soil. Getting rid of them is normally an arduous procedure with more bad sides than good sides, including blisters, aching backs, and time passed, which might have been better spent elsewhere. The one good side from weeding is probably the dead-tired, ‘sweat on your brow’ reward of seeing your garden rid of the unwelcome invasion.

But if you’re an itinerant farmer in Ghana, living near the Brong Ahafo gold mine of Newmont Ghana Gold Limited, one weed features another good side: it is being converted into a cash crop.

This weed, called Broussonetia papyrifera, or York, can consume arable land in a short time, growing 25-meter trees and a system of seeds and shoots that turns food-producing areas into wastelands.  Ghanaians may once have called it Devil’s Teak, now they see it as a raw material that can bring income to the villagers of Techeyre, who operate a micro business making biodegradable matting that is used for erosion control and slope stabilization at the nearby mining operation.

This micro business jute mat operation was conceived by Muhammad Bin Abubakar, an outspoken Newmont nursery manager who has left behind a large trail of good work, including growing a shaded forest where once there were only mining tailings. Bin, as he is known, says he learned of a way to use the tree when he worked at Newmont’s Indonesian operations.  According to Bin, one farmer, Amoafo Darkwah had to abandon his family’s two-acre cassava farm because of York infestation.

In the village of Techeyre, some 800 people, including Darkwah, join in stripping bark from these trees.  Bark stripped, the trees die within two weeks and will stop producing seeds. The dead timber can be used for minor construction needs or for cooking fuel, and much of the sawdust is used for growing at Bin’s nursery.

Then it’s time to treat the moneymaker, the bark. The fibrous material, taken from the bottom part of the tree, measures an average of one meter by five meters. This solid piece is first hammered flat so the fibrous structure can be pulled out, or woven into a continuous net material. The hammering process, where large hand-hewn mallets are used, resonates throughout the village with the sound of drums.

As Bin describes it, “ The mat is then woven into a mesh, just like chicken mesh, thus giving it the ability to trap eroded soil particles during storm periods.”

Beyond the environmental functionality of the jute mats, there is the micro business that has provided income for some 800 people where money or paying work are as scarce as the York is plentiful.

The difficulties posed by the York have been transformed into a solution, says Bin.

“So the jute mats are used for controlling erosion in our mining areas. Which now accounts for 800 people – ladies, men, and students in this area. And they are getting their livelihood from this work.”

We hope more micro businesses such as this one Bin has started begin popping up across Africa and other developing areas of the planet.
