About two kilometers from the Dead Sea and two from where Jesus was christened, in the country of Jordan, Geoff Lawton of the Permaculture Research Institute and his crew created a near miracle turning desert into a lush permaculture garden.

In August in this location, Lawton says that temperatures could rise above 50 degrees Celsius (122 degrees Fahrenheit). People farming there were farming under plastic strips and using tons of synthetic chemicals and fertilizers. The idea to grow a lush forest or garden of edible plants would probably make people laugh or roll their eyes. Nonetheless, the permaculture crew had exactly this vision in mind and a little funding to help them to do it.

In a first, researchers at the University of Washington in Seattle have developed a completely tree-powered electrical circuit.

The nano-scale device—approximately 130 nanometers [a nanometer is one billionth of a meter] in size—consumes just 10 billionths of a watt (10 nanowatts).

Unlike the legendary science fair experiment in which a potato-based electric circuit is created using two electrodes (each electrode being a different metal, which react with the starch, causing a potential difference and thus a current), the UW device utilizes electrodes comprised of the same metal, and is able to generate (output) 1.1 volts. “As far as we know, this is the first peer-reviewed paper of someone powering something entirely by sticking electrodes into a tree,” according to paper co-author Babak Parviz, associate professor of electrical engineering at the UW.

The World Agroforestry Centre has recently released a paper titled ” Trees on Farm: Analysis of Global Extent and Geographical Patterns of Agroforestry.” The researchers used five global geodata sets to estimate the percent tree cover on 22 million square kilometers of agricultural land around the world.  They were surprised to find that nearly half of that land had 10% or more tree cover (which is considered “significant” from an agroforestry point of view).  The area involved is vast - as large as the Amazon basin.

Even for North America, the percentages were surprisingly high (39% over 10% cover, 17% over 30%).  Values in Europe were similar. The highest levels are in central America (98% above 10% cover), South America (81%), and Southeast Asia (82%).  Overall, the lowest tree cover is in the most arid areas, but even there >20% of the farmland has 10% tree cover.

The destruction of 150 trees by a programme that has made real impacts on South Africa’s environment is regrettable but not really serious, until the underlying cause is questioned.

Removing Invasive Alien Plants

Water is a precious resource in short supply in South Africa. One of the activities directed at the problem is the Work for Water Programme, that works to remove alien invasive species which use large quantities of water unproductively.

Invasive alien plants (IAPs) are those introduced into countries from elsewhere, that then out-compete the indigenous species. They pose a direct threat to biological diversity, water security, the ecological functioning of natural systems and the productive use of land. They intensify the impact of fires and floods and increase soil erosion. IAPs can divert enormous amounts of water from more productive uses.

You’re waiting at a red light, your engine idling lightly. You check the crosswalk signal: 20 seconds, you have some time. You turn your classical music up a notch to the perfect volume and you close your eyes, relaxing on your way home from work. But your moment of relaxation is interrupted by the thump thump of bass coming from the car next to you. You look over at the car, the tinted windows keep you from seeing the driver. But the car’s engine revs. The light changes green and, as you lightly press the gas, the car next to you squeals past you, burning rubber.

Now, there is a lot of that situation that you would probably change. But I wonder if rubber made it high on your list. Well, it’s high on the list of researchers at Oregon State University. Their idea is not to do away with rubber altogether, but they are looking at the possibility of using trees in the tire-making process, which means that you and I could drive around on tires made partially out of trees some day.

Wood science researchers at Oregon State University have made some surprising findings about the potential of microcrystalline cellulose – a product made easily from almost any type of plant fibers – to partially replace silica as a reinforcing filler in the manufacture of rubber tires.

We’ve all heard the legend of Johnny Appleseed, the legendary apple tree planter of the United States. He walked across the country with his walking stick, and a bucket of seeds, just walking and planting as he went. Everywhere he went, apple trees sprouted up. And he was a hero. It is such a hero that Yosemite is looking for now.

The number of large trees is falling in Yosemite National Park, but no Johnny can be found. And the decrease is bad news for many species, including spotted owls, mosses, orchids and fishers (a carnivore related to weasels). These species, as well as others, are losing their habitat with the loss of the trees.

London’s mayor announced a new 2 million tree plan to help fight climate change and keep Londoners cool.

The plan is designed to counteract the “urban heat island effect” in which urban areas absorb and release more heat than surrounding areas, due to having more pavement, traffic and power demand.

One of the teams’ challenges in constructing a working sensor was that the device had to spend considerable time in “sleep mode” to conserve its limited power supply. This was problematic in that something was needed to “wake” the system up so it can do what it was intended to do. To solve this problem, the team invented a tiny clock mechanism to periodically wake the device up. The clock runs continuously on just 1 nanowatt of power, and, when fully turned on, uses just 350 millivolts (about one quarter the power of a AA battery).

Parviz points out that the nano-scale is not just a matter of size, but also one of power usage, and he anticipates more uses for such devices as a new generation of nano-electronics comes on-line.

The exact cause of this electrical tree power is not entirely understood but may involve the flow of dissolved mineral ions in the tree’s xylem–the specialized cells just inside of the tree’s cambium layer that transport water. And although too weak to ever replace solar power, tree-power can be used to monitor forest health, one tree at a time, and perhaps also monitor other signals from the environment (such as soil oxygen content, chemical signals from disease-causing pathogens, or heat increases that might indicate fire).

Additional co-authors of the paper include Eric Carlson and Ryan Ricchiuti, also of the UW. Research was funded in part by the National Science Foundation.

I love bears. Polar, Panda, Brown - you name it. Therefore I was immediately was fond of our books this week - a children’s book that takes place in a little bears’ heaven and where the main characters are bears (and very funny ones!).

Our book this week is:

The Legend of Honey Hollow

We mentioned it firstly last month when we announced on a collaboration with the author who plant a tree for every book sold on her signing events and provides buyers of the book with our sticker (made of recycled paper), saying: “One tree planted for this book”.

In my local community something is happening that makes me want to jump up, clap for joy and say, “thank goodness”! Children are being encouraged to get outside. Turn off the television and discover green grass, bugs, bond with the trees, smell the fresh air, run and get dirty. It’s an initiative that really shouldn’t have to take place but with television, computers, working parents and technology more children are inside verses exploring the great outdoors. Find out how to locally get involved or start an initiative near you by visiting Getting Kids Outdoors.

The idea is to leave no child inside. I found many helpful tips for parents on a handout given to me at our local health fair and hopefully you can use some of these tips and join in the effort to get our kids off the couch and outside where the rain won’t hurt them and some mud could be fun for everyone!

Limit Screen Time. Designate how often the television can be turned on and stick to it. Avoid using it just for noise. I’m guilty at this. My children love to just have the television on but they’re not watching it. It wastes energy and it’s just noise.

My girls seem to feel, however, (and I have to say that I agree), that trees are MUCH better for climbing than your general, run-of-the-mill playground monkeybars. Trees are more challenging, in that the layout of their branches and the way you can climb them is different for every tree, often different for the same tree as the seasons pass. Trees are real, as opposed to the manufactured play of the monkeybars, allowing children to test their actions in the real world, as opposed to the world made for them. And trees are natural, allowing my daughters, every time they climb, to learn everything from the texture of the bark to the way branches sway in the wind to the power contained in the height of any simple tree, and the power of being in that tree for yourself.

For almost exactly 20 years now, Trees for the Future has been coaching farmers on sustainable agroforestry techniques. That’s a fancy way to say farmers can improving their soil and crop quality by planting trees around the farm. The trees help by holding in soil moisture and drawing water back to refill water tables, preventing erosion and improving soil fertility.

Protecting the earth’s nearly 4 billion hectares of remaining forests and replanting those already lost are both essential for restoring the earth’s health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on reforestation.

There is a vast unrealized potential in all countries to lessen the demands that are shrinking the earth’s forest cover. In industrial nations the greatest opportunity lies in reducing the quantity of wood used to make paper, and in developing countries it depends on reducing fuelwood use.

The rates of paper recycling in the top 10 paper-producing countries range widely, from China and Finland on the low end, recycling 33 and 38 percent of the paper they use, to South Korea and Germany on the high end, at 77 and 66 percent. The United States, the world’s largest paper consumer, is far behind South Korea, but it has raised the share of paper recycled from roughly one fourth in the early 1980s to 50 percent in 2005. If every country recycled as much of its paper as South Korea does, the amount of wood pulp used to produce paper worldwide would drop by one third.

The use of paper, perhaps more than any other single product, reflects the throwaway mentality that evolved during the last century. There is an enormous possibility for reducing paper use simply by replacing facial tissues, paper napkins, disposable diapers, and paper shopping bags with reusable cloth alternatives.

A new way to treat wood has trees back in the limelight: a hardwood’s reliability that even a rain forest mahogany tree can love.

The above picture is of the world’s first heavy traffic road bridge made from Accoya® wood. The bridge, located in Sneek in the Netherlands, is “the first wooden bridge in the world that can support the heaviest load class of 60 tons”.  At this week’s Wall Street Green Trading Summit, a panel on forestation introduced a new way of thinking about how to deal with destruction of the rain forest.

>> More from the recent Wall Street Green Trading Summit:   Opening, Carbon Markets, Weird Investments and Solar Panels for All.

I think we can all agree that planting trees is a good way to go environmentally green (they capture carbon like crazy), but lets take a look at that other green for a moment: the green of cash.  Forestation can turn a profit quickly, given that it is one of the few industries in the United States that we know for sure will be cross marketable as a carbon offset industry.

Indoor entertainment certainly has its place but when they get outside to play or just enjoy a sunny day they get exercise and they connect with nature. Richard’s Louv’s book Nature Deficit Disorder is just full of reasons why we need to make a conscious effort to get our kids out of doors.

One simple way to do this is to take story time or homework outdoors.

Several dozen residents of San Francisco (also known as San Pancho) Mexico staged a spontaneous sit-in yesterday in the middle of their main thoroughfare to halt the destruction of hundreds of the city’s trees and the replacement of permeable paving stones with flood-causing impervious concrete. Local school children were joined by business owners and many other residents of the town who simply sat down in the middle of the road to stop the heavy machinery from destroying their street and native trees.
