"Carbon Dioxide Recovery from Industrial Processes," J.C.M.
Farla (Dept. Sci, Technol. & Society, Utrecht Univ., Padualaan 14, NL-3584
CH Utrecht, Neth.), C.A. Hendriks, K. Blok, Clim. Change, 29(4),
439-461, Apr. 1995.
Assesses possible techniques of recovering CO2 from large-scale industrial
processes, such as ammonia production, the iron and steel industry, and the
petrochemical industry. In some cases, the cost of recovery is significantly
less than that for CO2 recovery from thermal power plants. This option should be
studied further and considered if CO2 removal is introduced on a wide scale.
"Carbon Sequestration by Forests of the United States. Current
Status and Projections to the Year 2040," D.P. Turner (ManTech Environ.
Res. Serv. Corp., ERL, EPA, 200 SW 35th St., Corvallis OR 97333), G.J. Koerper
et al., Tellus, 47B, 232-239, 1995.
Model simulations show that U.S. forests are currently offsetting 6% of
fossil fuel emissions, but will come close to equilibrium by the 2020s. The
dominant factors driving the change are an increasing harvest, a decreasing land
base, and a reduction in average stand age. Increased paper recycling and
afforestation could produce a long-term increase in sequestration of up to 15
Special section: "Impacts of Harvesting and Site Preparation
on Carbon Cycling Processes in Forests," N. Zealand J. For. Sci.,
23(3), 1994. (Reprints are available from D.W. Johnson, Desert Res.
Inst., POB 60220, Reno NV 89506.)
Topics include roles of soil carbon in forest productivity and the global
carbon cycle, effects of forest management on soil carbon, and effects of rising
CO2 and possible climate change on soil carbon storage and other soil processes.
"Atmospheric Carbon Sequestration Through Agroforestry in China,"
X. Wang (Res. Ctr. for Eco-Environ. Sci., POB 2871, Beijing 100085, China), Energy,
20(2), 117-121, Feb. 1995.
During a study on biomass and productivity of agroforestry in the North
China Plain, found that agroforestry has a greater potential for storing and
absorbing carbon from the atmosphere than does land cultivation.
"Reforestation Trials in the Russian Far East [RFE]," R.F.
Lowery (Intl. Reforestation, Weyerhaeuser Co., Tacoma WA 98477), I.
Perevertailo, World Resour. Rev., 6(4), 477-489, Dec. 1994.
Seedlings, raised in the U.S. from RFE seeds and then planted in the RFE,
survived and grew well at a wide range of sites, including a large-scale
project. Given good logistical support and a well-trained work force,
reforestation of burned and harvested areas in the RFE should be successful.
"Sequestration of Atmospheric Carbon in India's Forests," A.N.
Chaturvedi (Tata Energy Res. Inst., India Habitat Ctr., Lodi Rd., New Delhi -
110 003, India), Ambio, 23(7), 460-461, Nov. 1994.
Briefly details the uses of forests in India, where the possibility of
increasing forest cover or carbon sequestration is minimal without changes in
management. These could include introducing forestry management with long
harvest rotations, and reducing the livestock populations grazing in the
