Google's philanthropic arm, Google.org, recently unveiled new software that can actually track and monitor global deforestation. If the software becomes more widely implemented, it could serve as a useful tool in helping to cut carbon emissions and combat climate change.

Google.org worked with Greg Asner of the Carnegie Institution for Science and Carlos Souza of Imazon to develop the deforestation program. To evaluate deforestation in a certain area of the world, the software relies on past, present and future models of satellite image data. 

Handle computation in the cloud
What if we could offer scientists and tropical nations access to a high-performance satellite imagery-processing engine running online, in the "Google cloud"?

And what if we could gather together all of the earth's raw satellite imagery data -- petabytes of historical, present and future data -- and make it easily available on this platform?

Google decided to find out, by working with Greg and Carlos to re-implement their software online, on top of a prototype platform we've built that gives them easy access to terabytes of satellite imagery and thousands of computers in our data centers.

By processing a decades  of historical images, it is able to extract scientific information on how the size and shape of tree cover has changed over the years. Google hopes that by arming scientists and forest managers with this valuable data, they can better protect the world's forests.

Start with satellite imagery
Satellite imagery data can provide the foundation for measurement and monitoring of the world's forests. For example, in Google Earth today, you can fly to Rondonia, Brazil and easily observe the advancement of deforestation over time, from 1975 to 2001:

Restoring devastated rainforest is a noble goal...but is it possible? 

Yes, says ZERI founder, Gunter Pauli.  Their organization turned waste into a productive, living, sustainable community.  It's a demonstration of natural systems-based environmental and economic development.

The Las Gaviotas reforestation project is not only about planting trees for climate stabilization; it is, primarily, about catalyzing a development program that will pave the way for creating a sustainable future for our children where society is able to provide for the basic needs of all in terms of water, food, health care, shelter, energy, jobs and education with local resources. Las Gaviotas is poised to do nothing less than reshape the face of sustainable development and, consequently, the world.

Imagine miles and miles of desolate savannah in Eastern Colombia, without a tree or bird or child in sight, a veritable no-man's land. For Paolo Lugari this was the perfect place to implement a vision: if a sustainable community could be created in such adverse environmental, social and political conditions, it could be done anywhere on the planet. Las Gaviotas has done just that, and much more.

In 1992, in conjunction with the Kyoto Protocol and the Japanese government, the Environmental Research Center at Las Gaviotas began substantiating the concept of carbon sinks to sequester carbon dioxide and stabilize the climate. Based on the cash generated by its renewable energy project, complemented with funding secured through the Japanese government, Las Gaviotas, founded and directed by Paolo Lugari, planted 8,000 HA of Caribbean pine trees in a savannah that had been unproductive for centuries. It was considered impossible to plant trees in such acidic, inhospitable soil (pH 4) but thanks to the innovative use of mycorrhizal fungi which acts as the saliva for the tree, the forestation was successful. More than just successful, this initiative to initiate economic activities and to validate carbon sinks unleashed a chain reaction of positive effects that surprised even the initiators of the program...

Today, more than a decade later, the forestation of 8,000 HA has resulted in 10 percent more precipitation (some 110,000 m³ per day), converting Las Gaviotas into a net supplier of drinking water, a crystalline water of superior quality. With the cost of drinking water exceeding the cost of petroleum, Las Gaviotas demonstrated that reforestation allows us to address one of the most critical issues the world is facing: access to natural potable water!

New Science Estimates Carbon Storage Potential of U.S. Lands
Nation's Forests and Soils Store Equivalent of 50 Years of U.S. CO2 Emissions

The first phase of a groundbreaking national assessment estimates that U.S. forests and soils could remove additional quantities of carbon dioxide (CO2) from the atmosphere as a means to mitigate climate change.

The lower 48 states in the U.S. hypothetically have the potential to store an additional 3-7 billion metric tons of carbon in forests, if agricultural lands were to be used for planting forests.

This potential is equivalent to 2 to 4 years of America's current CO2 emissions from burning fossil fuels.

"Carbon pollution is putting our world--and our way of life--in peril," said Secretary of the Interior Ken Salazar in a keynote speech at the global conference on climate change in Copenhagen, Denmark.  "By restoring ecosystems and protecting certain areas from development, the U.S. can store more carbon in ways that enhance our stewardship of land and natural resources while reducing our contribution to global warming."

U.S. Geological Survey scientists also found that the conterminous U.S. presently stores 73 billion metric tons of carbon in soils and 17 billion metric tons in forests.

This is equivalent to more than 50 years of America's current CO2 emissions from burning fossil fuels. This shows the need to protect existing carbon stores to prevent additional warming and future harm to ecosystems.

Habitat Carbon Absorption = 30% of Fuel Emissions

America's forests and soils are currently insufficient in soaking up the nation's accelerating pace of emissions. They currently absorb about 30 percent (0.5 billion metric tons of carbon) of the nation's fossil fuel emissions per year (1.6 billion metric tons of carbon). Enhancing the carbon storage capacity of America's and the world's ecosystems is an important tool to reduce carbon emissions and help ecosystems adapt to changing climate conditions.

Biologic carbon sequestration

"The tools the USGS is developing--and the technologies behind those tools--will be of great use to communities around the world that are making management decisions on carbon storage," said USGS Director Marcia McNutt. "The USGS is conducting a national assessment of biologic carbon sequestration, as well as an assessment of ecosystem carbon and greenhouse gas fluxes, which will help determine how we can reduce atmospheric CO2 levels while preserving other ecological functions."

To determine how much more carbon could be stored in forests and soils, USGS scientists analyzed maps that represent historical vegetation cover before human alterations, as well as maps of vegetation that might occur if there were no natural disturbances, such as fires, pests and drought. These maps were compared to maps of current vegetation and carbon storage.

The next phase of this work will assess the additional amount of carbon stored in Alaska's ecosystems, including its soils and forests. The USGS plans to collaborate with U.S. Department of Agriculture and other agencies to examine potential carbon storage in soils.

The USGS is conducting research on a number of other fronts related to carbon sequestration. These efforts include evaluating the potential for storing carbon dioxide in geologic formations below the Earth's surface, potential release of greenhouse gases from Arctic soils and permafrost, and mapping the distribution of rocks suitable for potential mineral sequestration efforts.

Pacific Northwest temperate rainforests can attain the greatest biomass per acre of any ecosystem on earth.  Wow!  Did you know that?  I didn't.  Temperate and boreal forests are very extensive and currently serve as net carbon sinks.  And that's a good thing --  a very good thing!

Carbon storage by forests is complementary with other important ecosystem services provided by forests.

• Clean Water
• Fish and wildlife habitat
• Soil conservation
• Economic diversification
• Capture, storage and release of water, nutrients and sediment
• Air filtration
• Mediation of urban heat islands
  

Kyoto Protocols limited the credits given to established forests, but that approach to carbon sequestration and carbon offsets is changing.  Mature trees are storage tanks for high levels of carbon and particulates. 

The Athena Sustainable Materials Institute provides comparative  data for construction materials including wood, steel and concrete that takes a total energy use approach that includes total energy use, above grade energy use and CO2 emissions.   Wood is a superior material in this life-cycle inventory of large office building applications.

Carbon Dioxide in Forests

Tree growth sequesters considerable quantities of carbon:

• Dry wood is 49% carbon by weight
• For each pound of carbon stored, 3.7 pounds of carbon dioxide are removed from the atmosphere.
• For each pound of carbon stored, 2.7 pouds of oxygen are produced.
• Carbon is also stored in the soil, the litter, and in the trunks, branches, twigs, leaves, and roots of trees.

Trees also provide valuable habitat and food for biodiversity that converts plant matter into protein, which is vital for the animal kingdom.  Caterpillars and birds are key players in this highly productive food conversion process.

• Air filtration of regional pollutants

• Sequestration of carbon dioxide

• Restoration of soils

• Replenishment of underground fresh water storage and aqufers

• Reduction of mountainous flooding, and storage of snow pack for water supplies

• Habitat for wildlife and biodiversity preservation

• Outdoor recreation places and spaces

• Temperature moderation with moisture, shade and the cooling effects of solar absorption

Forestry Carbon Sequestration

Atmospheric carbon dioxide is a gas and forests play a role in its natural regulation.  CO2  - carbon dioxide -- is a gas that occurs naturally in the atmosphere, but it is also being produced with modern transportation and industry.  The result is an imbalance.

Sustainable forestry can hold sequestered carbon in its wood, leaves, root systems, and the soil fertility that results from natural decomposition of organic matters.  Sequestration is the scientific term used for a "storage tank".  Trees act as storage tanks for carbon dioxide by naturally absorbing carbon through photosynthesis.  As trees reach maturity, their growth rates slow depressing any new storage capacity.  Sustainably harvesting mature trees that have extremely slow sequestration rates is a way to keep carbon captured in woods that can be used in housing, furnishings and other long term applications.

Carbon Offset Credits

Sustainably manged forests can document their long term forestry management plan and keep an accurate inventory as the baseline for a sustainably managed, working forest.  These sustainable forests provide multiple benefits in the natural resources system.  In addition to producing carbon sequestering wood products, the working forest also filters ground water, controls erosion, restores soil quality, improves air quality by absorbing pollutants and carbon dioxide ... and provides recreational opportunities.

Carbon Credits

Carbon credits are an attempt by regional and national conservation economies to mitigate the growth of greenhouse gases.  Forests are a key player in the new carbon credits market.

Carbon trading is an emissions trading approach that lets companies buy sustainable credits to offset their not-so-environmentally friendly operations such as transportation or industrial production that uses fossil fuels and produces greenhouse gases.  By purchasing carbon credits to meet their legal compliance levels, these companies buy a little extra time to implement their own emissions reduction strategies.

Greenhouse gas emissions are capped by agencies such as the EPA as well as state based environmental and air quality agencies.  Markets are used to allocate the load of emissions among the group of regulated sources -- usually large manufacturing corporations. 

By having to purchase high priced carbon credits, compaies are encouraged to implement better, less expensive options that reduce their own emissions.  The more they succeed internally in reducing particulates and carbon dioxide, the fewer carbon credits they need to purchase to meet their compliance allocations.

Mitigation projects generate credits, so highly effective companies can sell their extra credits to generate revenue.  This income can be used to finance carbon reduction programs between partners and around the world. 

These carbon offset players can purchase credits from an investment fund or carbon development company that aggregates credits from approved, sustainable programs such as the Michigan Timber Conservation Carbon Off-Set Program.

Two current approaches to carbon reduction ar recognied as effective ways to reduce carbon emissions and climate change.  

Carbon offset credits consist of clean forms of energy production such as wind, solar, hydro and bio-fuels.

Carbon reduction credits consist of the collection and storage of carbon from the atmosphere through reforestation, forestation ocean and soil collection and storage processes.

Carbon Financial Instruments (CFI)

Forest owners who provide a sustainable, working forest can sequester carbon dioxide and offset current carbon levels through sustainably certified forest management and certified wood products.  The Forest Stewardship Council (FSC) program is one example of sustainable forestry and product certification programs.

Carbon Offset Programs typically include forestry management strategies such as:

• land management portfolio
• complete forest inventory
• written management plan
• record keeping of all forest studies
• market driven carbon royalty payments
• aerial, land, and soil maps
• revenue from land tax credits
• using FSC certified harvesters
• ongoing forest analysis

 

Some of the benefits of participating in a sustainable forestry and offset program include:

• guaranteed market value of wood products
• sustainable forest recognition
• improved roi on timber products
• unlimited access to online forestry portal
• timber theft prevention program
• member referral program

The goal of sustainably harvested forests and timberland is a responsible, ethical business approach that promotes positive forestry growth and sequestration of carbon in wood products.  This is a promising approach to reducing greenhouse gas effects caused by environmental emissions and heat from urban, industrial, transportation and other sources of modern energy side effects.

If your private forest has harvestable, merchantable timber, you can still use your timberland for wood production as long as it is managed in a sustainable, planned, measured and long term way. 

Many regional sustainable forestry organizations, such as the Michigan Timber Conservation Carbon Off-Set Program, will help train and support landowners and forestry companies with management plans and a forest inventory to prepare the forest for carbon credit program participation.

In a 2008 report, the Governor's Minnesota Climate Change Advisory Group (MCCAG) recognized the importance of forests in greenhouse gas reduction by suggesting that nearly 30% of the state's 2025 greenhouse gas emission reduction goals could be achieved through forest management initiatives.

Forestry Carbon Credits help provide new funds for conservation. 

Princeton Biology and Public Policy Professor Lee Silver describes a vision (admittedly "sci-fi" for now) in which biotechnology has taken over the natural world--but in a responsible, sustainable way. He looks forward a potential distant future where, for example, trees are engineered to produce fuel.

"If you can imagine something," he says, "it's probably going to be done."

The bad boy of biotech has a vision... "we want to have renewable fuel... that doesn't affect the atmosphere. We want to maintain nature and forests...we love them. And we want to do it sustainably. Craig Venter wants to create organisms that are trees that produce diesel fuel...or some other source of energy. Sunlight is converted directly into fuel. That's what plants do...convert sunlight into energy...." (Craig Venter Received an EMC Information Leadership Award)

The forest provides comfort to us, the fuel is carbon neutral and the fuel is then used to create hydrogen fuel or some clean fuel. It's all dependent on manipulating the earth... like we've been doing for hundreds or thousands of years.

That's the future science fiction visionaries are seeing... biotech is the pathway through the forests of tomorrow.

Hmmmm....

A study of the magicians of the soil is an endless endeavor! Paul Stamets makes it a bit easier to learn about mushrooms with this TED talk. Mushrooms are both a citizen of the micro world of soil, but they are the manufacturers of the very soil in which they live. What a sentient approach to sustainability.

A recent study at Oregon State University has shown that native bumble bee species have consistently high pollination and seed production levels in red clover.

The bumble bee pollination findings offer promise for the use of bumble bee crop pollinators as an alternative to European honey bees, whose populations have recently declined in many areas of the United States.

Red clover, which is grown for forage and as a rotation crop to improve soil, is raised for seed in western Oregon's Willamette Valley. It will not produce seed without pollination, so growers typically place two to five European honey bee hives on each hectare. 

Search for Alternative Pollinators

Bee diseases, mites, and colony collapse disorder have recently limited availability and resulted in higher costs for hive rentals. Given these changes, an alternative pollinator for red clover seed crops is needed.

Worldwide there are over 200 species of bumble bees; some of whom are known to pollinate red clover. While commercially reared bumble bee species are available to growers elsewhere, they are considered exotic species in Oregon and cannot be introduced into the state. This leaves Oregon growers dependent on naturally occurring populations of bumble bees as pollinators. However, there is currently no information on the pollination efficiency of native bumble bee species.

Scientific Evaluation of Blooms and Seed Set

Through funding from the Clover Commission, scientists at Oregon State University investigated native bumble bees in commercial fields of red clover seed crops in the Polk County region of the Willamette Valley. Prior to bloom, researchers covered plants with mesh-screened cages. European honey bee hives were placed in some cages and nests of B. vosnesenskii, a native Oregon bumble bee,in others. Some cages were also left vacant. After bloom, seed yield and seed set were compared amongst the different cages. Seed set was also evaluated in four different fields without cages to assess the efficiency of existing bee pollinators. In addition to analyzing seed set, researchers assessed the diversity and abundance of native bumble bees through visual observations of foragers on red clover flowers and through trapping bumble bees in blue vane traps. 

Pollination Differences between Bumble Bees and Honey Bees

While there were no differences in seed yield or average seed set in cages with bumble bees compared to honey bees, the study revealed:

• Variability across cages was lower with bumble bees indicating that bumble bee pollination is more uniform than pollination by European honey bees.
  
• The abundance of bumble bee peaked during mid-to-late bloom.
  
• They recorded six species of bumble bees gathering pollen from red clover flowers. Of these, more than 92% consisted of B. vosnesenskii, indicating that it is the key pollinator in Oregon.
  
• 25 more species of native solitary bees, belonging to 12 genera and five families, were collected in the bee traps.

Research Findings

The study has not only documented a great diversity of native bees in synchrony with red clover bloom, but it has also found that seed set was uniform and high across four fields. Under current pollinator regimes, researchers believe red clover seed production is close to its maximum in Oregon.

Solutions for Pollination

"To sustain these high yields in Oregon, we must

• Conserve the habitat of bees,
  
• Use pesticides judiciously and
  
• Provide floral resources prior to red clover bloom

Oregon State University entomologist Sujaya Rao, one of the researchers on the study, concluded,  "Globally, where red clover seed is produced, similar studies are needed. If seed set is found to be well below the maximum, appropriate alternative options such as augmentation with commercial bumble bees could be considered."

Research is ongoing at Oregon State University to determine whether high yields can be achieved by native pollinators alone. If so, European honey bee hive rentals would not be required, and this could lead to more economic red clover seed production in Oregon.
