How can we create jobs, reduce food prices and boost economies?
The fate of heads of state across the globe is tied in large part to their ability to ensure employment, economic growth, and access to cheap food and clean water. Rising food prices have helped topple dictators across the Middle East. Europe, the United States, Japan and other major economies are spending trillions of dollars to restore growth and jobs. Too often, efforts to address ...

Survey of lanthanoids in plants from a tropical region
Several anthropogenic sources may provide lanthanoids (La, Ce, Nd, Sm, Eu, Tb and Yb) to the agricultural and forestry landscapes. Because little information is available on the distribution of these chemical elements in Brazilian tropical ecosystems, this work focuses on the survey in leaves of diverse plant species (native trees, epiphytes and crops) from different ecosystems. Soil under crown ...

Taxpayer dollars subsidizing destruction
One way to correct market failures is tax shifting—raising taxes on activities that harm the environment so that their prices begin to reflect their true cost and offsetting this with a reduction in income taxes. A complimentary way to achieve this goal is subsidy shifting. Each year the world's taxpayers provide at least $700 billion in subsidies for environmentally destructive activities, such ...

Ohio slope erosion, Cleveland, Ohio - Case Study
Every day, over 100,000 vehicles drive on I-480, a six lane Interstate highway around Cleveland, Ohio. To improve the appearance and correct some heavily eroded areas, the Ohio Department of Transportation decided to landscape 3.5 miles (5.6 km) of both cut and fill slopes on the north side of I-480. Their plans called for regrading, draining, and planting trees, shrubs and various plants. ...

Could food shortages bring down civilization?
One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...

Protecting and restoring forests
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 ...

Not just hot air — global diplomacy and the search for a successor to Kyoto
Every winter the gates of Copenhagen's famous Tivoli Gardens, an old world amusement park in the city centre, open to officially mark the beginning of the extended Christmas period. This December the twinkling lights of Tivoli will most likely be outshone by COP 15 — the most important global climate change meeting ever — as thousands of diplomats, politicians, business people, environmentalists ...

Planting trees and managing soils to sequester carbon
As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...

Cross inoculation studies: Response of Vigna mungo to inoculation with rhizobia from tree legumes growing under arid environment
Cross-inoculation experiments were conducted in the greenhouse to test the rhizobia isolated from nodules of seven tree legumes for their effectiveness in Vigna mungo plants. The tree legumes included Albizia lebbeck, Dalbergia sissoo, Leucaena leucocephala, Pithecellobium dulce, Prosopis cineraria, Prosopis glandulosa and Prosopis juliflora, all growing under arid environment. Rhizobia from ...

Public perceptions of hybrid poplar plantations: trees as an alternative crop
This paper describes the differences between expert and public perceptions of plantation forestry and calls for greater public participation in the development and establishment of plantations. The debate over the social acceptability of varying land-uses is essentially a debate over how land is valued and the effects of land-use change on local peoples. This study reports the findings from 31 ...

Forest biotechnology: an extension of tree improvement
Forest genetics as a science has existed since the 1940s. With the depiction of the structure of DNA in 1953 by Watson and Crick, some forest geneticists were inspired to apply this knowledge to trees. Since that time the science of molecular biology has evolved considerably. This paper summarises the applications of biotechnology to trees, the traits and trials for genetically engineered trees, ...

CORNucopia of Opportunity in the Heartland: Or Just More Feed for the Political Cattle?
We now live in a carbon constrained world. Fears of human induced climate change are bringing about changes in government, corporate and consumer behaviors. Investments in renewable energy are increasing, corporations are greening everything from their supply chain to their vehicle fleet, and consumers are seeking to minimize their ecologic footprint as well. Are some of our greening efforts ...

Trees, bees and UBCs
Tonnes of aluminium cans and foil recycled in the UK are being turned into new trees to provide food, medicines and income for the people of Burkina Faso in West Africa - one of the poorest countries in the world. This article explains the workings of an innovative collaboration. A30-year-old subsistence farmer and mother of five stands proudly next to a sapling in the stifling heat of an ...

Environmental impacts of community-based forest management in the Philippines
Community-based forest management (CBFM) is a major strategy in managing forest lands in the Philippines. Forest and land management activities implemented in CBFM project sites include management of tropical forests (enrichment planting, timber stand improvement or TSI and limited harvesting), rehabilitation of degraded lands (reforestation, assisted natural regeneration (ANR)) and agroforestry. ...

Aftermath of the Long-Term Application of Sludge and Water from a Sewage Treatment Plant to a Lemon Tree (Citrus limon) Plantation
The effect of sewage sludge application to agricultural soils in industrial countries (Raven and Loeppert 1997; Towers and Horne 1997) and that of the treated domestic and industrial effluents on plants (Hooda et al. 1997; Logan et al. 1997; Palacios et al. 1999; Samaras and Kallianou 2000, Weir and Allen 1997) have been ...

Influence of Tree Species on Forest Nitrogen Retention in the Catskill Mountains, New York, USA
This study examines the effect of four tree species on nitrogen (N) retention within forested catchments of the Catskill Mountains, New York (NY). We conducted a 300-day 15N field tracer experiment to determine how N moves through soil, microbial, and plant pools under different tree species and fertilization regimes. Samples were collected from single-species plots of American beech (Fagus ...
