KONZA PRAIRIE SOIL RESEARCH: 
IMPROVED MANAGEMENT CAN HELP REDUCE GLOBAL WARMING

 
Improved management of the tallgrass prairies of the Flint Hills may benefit more than just the rangeland grasses. It also could benefit the entire globe by helping reduce the level of greenhouse gases that can cause global warming, according to Charles W. Rice, professor of agronomy at Kansas State University. 
Two of the most important management factors for tallgrass prairie systems such as the Konza are prescribed burning and grazing management. About 30 percent of the rangeland in Kansas is currently being burned too early in the spring, being overgrazed, or has poor grazing distribution. 

Each spring, thousands of acres of tallgrass prairie are burned to clear the mulch that inhibits the growth of tall grasses. Burning may also help reduce the level of carbon dioxide in the air, according to Rice, who has conducted both long- and short-term research on the soil properties at the Konza Prairie Biological Station. 
“Research is showing that prescribed burning of tallgrass prairie increases the conversion of harmful atmospheric carbon dioxide into beneficial stored soil organic carbon. This is a process called carbon sequestration,” said Rice. 
Burning at the proper time (late spring) increases plant growth, and this increases the amount of carbon dioxide absorbed by plants. Carbon dioxide is a “greenhouse gas,” which contributes to global warming. Since much of the plant growth in tallgrass prairie occurs belowground the carbon dioxide that is converted by plants into root material is processes by soil organisms into soil organic carbon thus potentially reducing carbon dioxide. In addition biological production of nitrous oxide, another greenhouse gas, is also reduced in burned prairie. 
 
Mycorrhizal fungi, an important soil microbe essential to the health of many prairie plants, also plays a role in stabilizing soil particles which protect carbon in the soil, Rice said. 

Grazing pressure and distribution is the other key management practice. By reducing grazing pressure on land currently being overgrazed, and by improving distribution of livestock, grass production can be increased significantly over time. As with properly timed prescribed burning, this increase in forage production through grazing management will increase carbon sequestration rates, Rice says. 

Much of his research takes place in the field, so plant and soil samples are indicative of the entire population. From that point, some work takes place in a laboratory, where the soil organic matter is divided, and examined how much carbon is tied up in microorganisms and how much is available," Rice said. 

Another research method that Rice has utilized is the addition of stable isotopes of both 
carbon and nitrogen. This allows the researchers to find out exactly how and where carbon and nitrogen are changing in the soil and atmosphere after grassland is burned. 
As concerns about global warming continue to grow, the increased carbon absorption capacity shown in Rice's research could become a tool to counteract the problem in the future. 
"Can we manage these ecosystems and the amounts of carbon dioxide in the air? That’s the ultimate question we are trying to answer," Rice said.

Study Evaluates Ocean Fertilization in Reducing CO2

The Woods Hole Oceanographic Institution (WHOI) recently announced that WHOI researcher Ken Buesseler and University of Otago researcher Philip Boyd have released the findings of a new study which suggests that reducing atmospheric carbon dioxide (CO2) by fertilizing the oceans with iron "may not be as attractive a solution as once thought."

WHOI noted that the "controversial" idea of ocean fertilization as a means of reducing CO2 initially "gained momentum" in the 1980s, with climate and ocean scientists theorizing that the addition of iron to the ocean surface would increase the production of plankton, which "take up carbon in surface waters during photosynthesis, creating a bloom that other animals feed upon" and subsequently deliver to the seafloor in the form of waste known as "marine snow."

According to the researchers, three open-ocean experiments in which iron was used to fertilize large sections of the Southern Ocean "all produced significant increases in planktonic biomass and decreases in dissolved inorganic carbon in the water column." However, Buesseler and Boyd said there was limited evidence "that the particles carried large quantities of carbon to the deep ocean," leading to concerns about "the space and time scales needed for commercial applications and the inefficiency of [the] process."

Cooperative Reforestation Project In Texas 
Provides Carbon Sequestration Credits 

A diverse group of public and private partners, including Texas Parks and Wildlife Department (TPWD), Reliant Energy, The Conservation Fund and Environmental Synergy Inc. (ESI), recently unveiled the nation’s newest carbon sequestration project at a public ceremony in Austin, Texas. Through a market-based approach that benefits business and the environment, the partners joined forces to create a conservation solution will offset the environmental impacts of greenhouse gasses, provide new fish and wildlife habitat and bring recreation-driven economic benefits to east Texas.

On behalf of TPWD, The Conservation Fund acquired nearly 600 acres of converted pastureland, which will be included into the Old Sabine Bottom Wildlife will fund the reforestation of the property, planting approximately 162,500 native trees, in an effort to address climate change, restore wildlife habitat and improve air quality. Over the next 70 years, these trees will capture an estimated 215,000 tons of carbon dioxide from the atmosphere, generating “carbon credits” that will be retained by Reliant.

In addition to offsetting greenhouse gases, this newly created bottomland hardwood forest will improve water quality, provide opportunities for outdoor recreation and serve as important habitat benefiting migratory songbirds, waterfowl, white-tailed deer and other wildlife. The lands will be added to the 5,167-acre Old Sabine Bottom Wildlife Management Area, located in Smith County, as part of a regional conservation strategy to preserve large tracts of bottomland hardwood forest, decrease habitat fragmentation and reduce urban sprawl in east Texas.

"This type of public-private partnership represents a powerful breakthrough in using voluntary and market-driven approaches to address two of the nation’s top environmental concerns -- climate change and habitat protection,” said Lawrence Selzer, president of The Conservation Fund.

These projects, structured to scientifically monitor carbon sequestration over time, take advantage of the fact that as plants grow, they incorporate carbon from the atmosphere into their structure through the process of photosynthesis. Sequestration programs encourage corporations and governments to plant trees to offset the impact of carbon emissions. Working with the public and private sectors, The Conservation Fund has partnered with ESI, an Atlanta-based company, on three previous carbon sequestration projects.

EUROPE MOVES CLOSER TO ENERGY DEMAND LAW

BRUSSELS, Belgium, April 9, 2003 (ENS) - Managing the demand for energy is emerging as a European strategy for meeting the targets set by the Kyoto Protocol for the reduction of greenhouse gas emissions.

These emissions of carbon dioxide and other gases occur when fossil fuels such as coal, oil and natural gas are burned to produce energy. The European Commission will propose an EU law on energy demand management by the summer, according to sources. The long promised measure is intended to boost energy efficiency and help meet the EU's Kyoto Protocol commitment to reduce greenhouse gas emissions. Initial proposals by the Commission's Energy Directorate are said to envision a range of actions designed to influence energy users.

Among these will be a first ever European Union push to encourage the development of an energy services market in which services involving the use of energy are sold, rather than the energy itself.

In the past, efforts to promote the provision of energy services by power companies stalled for reasons ranging from low consumer interest to poor incentives for suppliers, since electricity prices started falling as a result of liberalization.                                          

The new law, known as a directive, appears likely to endorse a "market orientated" approach that would enjoy the support of the electricity industry. “There's an underlying need and potential for cost-effective measures," an EU source said, and a growing awareness that, with energy markets liberalization now fully under way, the demand side needs to be addressed. "If we provide the right framework and incentives, the rest will probably fall into place," the source added.

The directive would set indicative targets for countries that are members of the European Union to achieve one percent annual savings in energy efficiency. Each country would then decide how to distribute this target among sectors.

The Commission envisages covering all distribution sectors, from electricity and gas to district heating and transport fuel. An estimated 40 to 45 million metric tons of carbon dioxide emissions could be saved every year once the directive comes into effect, according to a study carried out for the EU's climate change program.

Controversially, the new directive aims to cover all end users, including non-energy intensive industries and transport, except for aviation and foreign shipping. "We're very keen to see the transport sector included," our source said, "since it's contributing most to the increase in greenhouse gas emissions."

The public sector would have special responsibilities through additional green procurement requirements. Financial instruments would be put in place to facilitate the buying and selling of energy services, and to support the setting up of specialist energy services companies.

JAPAN TO INTRODUCE 'ENVIRONMENT TAX' DESPITE KYOTO PROGRESS

Officials with Japan's Ministry of the Environment (MOE) recently announced the agency will introduce a new "environment tax" intended to help the country meet its greenhouse gas (GHG) emission reduction requirements under the Kyoto Protocol regardless of whether the treaty enters into force next year.

"We must make efforts to curb global warming even if the protocol does not come into effect next year," said MOE vice minister Masaharu Nakagawa. Under its Kyoto obligation, Japan is required to reduce GHG emissions to six percent below 1990 levels by 2012.

MOE said the treaty, which must be ratified by 55 states representing 55 percent of the carbon dioxide (CO2) emissions produced by developed nations in 1990 to become effective, will enter into force 90 days after being ratified by Russia.
