Calculation and analysis of genuine saving for forests in China
'Genuine Saving' is an indicator which reflects the practical steps towards sustainability. This paper for the first time estimates the Genuine Saving for forests in China. The results show that the Genuine Saving for forests in 1999 was 10290.25 billion Yuan (RMB) and 19402.52 billion Yuan in 2003. This shows that the annual increasing rate was 17.18%, which is higher than the traditional annual ...

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, ...

Soil nitrate leaching in silvopastures compared with open pasture and pine plantation
Wide acceptance of silvopasture as an alternative sustainable agricultural system in the southeastern United States will depend on an improved understanding of the tree-forage interactions and recognition of its environmental benefits. The objective of this study was to evaluate differences in soil nitrate leaching in different land-use systems, in north Florida. An 18-yr-old loblolly pine (Pinus ...

Soil nitrate leaching in silvopastures compared with open pasture and pine plantation
Received for publication December 5, 2007. Wide acceptance of silvopasture as an alternative sustainable agricultural system in the southeastern United States will depend on an improved understanding of the tree-forage interactions and recognition of its environmental benefits. The objective of this study was to evaluate differences in soil nitrate leaching in different land-use systems, in north ...

Impacts of harvest residue management on soil Carbon stocks in a plantation forest
The impacts of plantation forest management on soil C stocks in New Zealand need to be better understood for the purposes of C accounting under the Kyoto Protocol. We investigated the impacts of three harvest residue management treatments on C and N stocks in a scoriaceous forest soil: whole-tree harvesting plus forest floor removal, whole-tree harvesting, and stem-only harvesting. Volumetric ...

Environmental and social impacts of oil palm cultivation on tropical peat
The palm oil sector has created in the past few decades millions of jobs. Over the next decade, the Indonesian government plans to double the annual production of palm oil, creating new jobs for an estimated 1.3 million households. Although the cultivation of oil palm on peatlands creates new income opportunities for many farmers in the short term, longer term economic implications remain ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

Book Byte: We Can Reforest the Earth
Protecting the 10 billion acres of remaining forests on earth and replanting many of those already lost are both essential for restoring the earth’s health. Since 2000, the earth’s forest cover has shrunk by 13 million acres each year, with annual losses of 32 million acres far exceeding the regrowth of 19 million acres. Restoring the earth’s tree and grass cover protects soil ...

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 ...

5 lessons for sustaining global forests
As the old adage suggests, it is important to see the forests for more than just the trees. While an estimated 500 million people depend directly on forests for their livelihoods, the entire world depends on them for food, water, clean air, and vital medicines. Forests also absorb carbon dioxide, making them critical to curbing climate change. Despite some encouraging anti-deforestation efforts ...

El Niño: Meet the man who tries to predict the unpredictable
In 1985, El Niño research pioneers Mark Cane and Steve Zebiak came up with the first computer model that successfully predicted the periodic Pacific Ocean warming event the following year. Thirty years later, models have improved — but El Niño remains an elusive beast, says Cane. “The models have gotten better and better, there is no question about that.” However, ...

Global Forest watch - join the movement
We know remarkably little about what is happening to forests. Businesses currently have no way of determining whether or how much the soy, palm oil, or pulp and paper they use contribute to deforestation. So companies like Unilever and Nestlé, which have committed to halting deforestation in their supply chains, are unable to measure progress toward this important goal. Concerned ...

Happy TuBishvat from Tal-Ya
Happy TuBishvar for all the trees in Israel and in the world. Tu-Bishvat is the Jewish holiday where we are celebrating nature growth and thanksgiving. With Tal-Ya platform, the forest’s young trees, which are left to survive in the arid climatic conditions, have a substantial better chance to survive due to the surrounding support the platform provides to the tree – mitigation of ...

An ecological assessment of greening of Aravali mountain range through joint forest management in Rajasthan, India
Rajasthan is one of the largest Indian states with about 9% of its total geographical area covered with forest. Large area of the state is covered with desert, has one of the highest livestock populations and therefore has severe shortage of biomass for local use. The community forestry initiative in this state has resulted in significant regeneration, enhanced biomass and enhanced tree cover in ...

Intro to precision forestry
Never before has the interest in preserving natural forests and efficient management of plantations been as great as the present. Demand for wood products is increasing. On the other hand, it is also evident that the remaining forests have to be protected to maintain our quality of life—the very air we breathe depends on them. Therefore, precision management, which has been successfully ...

Rajang Delta threatened by floods
This paper presents a case study of the Rajang Delta in Sarawak, Malaysia where peatland subsidence will cause flooding, rendering more than half of the Rajang Delta unsuitable for any agriculture cultivation due to severe floods in 50 years. The land area which will be inundated is 3 times the size of Singapore!! What a great loss! Case study summary: The case study reveals that about 87% of ...

Shrinking forests: The many costs
In early December 2004, Philippine President Gloria Macapagal Arroyo 'ordered the military and police to crack down on illegal logging, after flash floods and landslides, triggered by rampant deforestation, killed nearly 340 people,' according to news reports. Fifteen years earlier, in 1989, the government of Thailand announced a nationwide ban on tree cutting following severe flooding and the ...

“Swapping Land” to Produce Sustainable Palm Oil in Indonesia
Indonesia has the world’s third-largest rainforest, which is a haven for biodiversity and an economic lifeline for many rural communities. However, Indonesian forests are in rapid decline and the country regularly tops deforestation hotspots lists. The key to protecting Indonesia’s forests remains reforming its massive forestry and agriculture sectors. By giving these industries the ...

Facts & figures on palm oil
Introduction Palm oil is a vegetable oil that is a common ingredient in a wide variety of products, ranging from biscuits, bread and noodles to shampoo, candles and deter-gents. It has been estimated that around half of all packaged items found in supermarkets contain it. Palm oil is also used as biofuel. The use of palm oil is expected to continue growing, with an esti-mated doubling of use by ...
