An Indonesian government volcanologist reports that Mount Merapi spewed lava and ash many times on Saturday, renewing fears of a devastating volcanic eruption.

Government geologist Subandriyo said that Merapi’s lava dome has swelled 56 feet (17 m) in the past week to a height of 330 feet (100 m), raising fears that it could collapse and release a pyroclastic flow of hot gases and rock fragments burning everything in its path. The quake is believed to contribute to the growing instability of the lava dome, scientists said.

The mountain also sent about 90 trails of molten lava down its western slope on Thursday, said geologist Tri Yani.

The announcement comes one week after a 6.3 magnitude earthquake struck the city of Yogyakarta, killing at least 6,000 people and injuring tens of thousands more. Since then, the region has experienced over one thousand aftershocks – most were weak, but some were strong enough to jolt villagers awake in the area.

Villagers in the vicinity of the mountain have started performing ancient religious rituals aimed at averting an eruption. The royally appointed guardian of the mountain, “Mbah” Maridjan, was reported to have led a silent procession of about 100 people on a march around a village near the volcano.

In an effort to ease complaints by the U.S. and Europe about a heavy influx of low priced Chinese goods, China will raise export tariffs on 74 categories of textile products in June. This follows plans from the U.S. to impose quotas on Chinese textiles and clothing.

Products likely to see an increase from the Chinese move include synthetic fiber shirts, trousers, knit shirts and blouses, cotton shirts, and combined cotton yarn. Last week, similar restrictions were imposed by the U.S. on cotton trousers, knit shirts, and underwear. Currently, a 2.5 cent charge per item is imposed; the new tariff will raise this to the equivalent of 12 cents per piece now. While this is a fourfold increase, it is not expected to affect consumer prices. Because of this, some doubt the tariff will have any effect on correcting the trade imbalance.

This move is in response to U.S. trade quotas imposed due to concerns that increased Chinese goods would put U.S. textile manufacturers out of business. According to Auggie Tantillo, executive director of the American Manufacturing Trade Action Coalition, a textile industry group in the U.S., the move will preserve 10,000 U.S. jobs. The new U.S. trade quota will limit the growth of Chinese textile imports to 7.5 percent compared with shipments over the past year.

Prior to January 1, a global quota system helped regulate the trade. With the quota system gone, fears have arisen that a flood of Chinese goods could undercut U.S. competitiveness in the market. China is able to market its goods cheaply due to an artificially weak yuan. The U.S. Treasury criticized the China yuan policy as “highly distortionary”, posing a major risk to China’s economy itself and to global economic growth. They challenged China to revalue its currency to bring it to a level they believe will allow fairer competition between global manufacturers.

China has disputed the charges of the U.S. Treasury. Chinese Commerce Minister Bo Xilai said, “I believe they are not reasonable”.

Laura Jones, a representative of large retailers, also criticized the move, saying “These restrictions on imports from China will do absolutely nothing to help the U.S. textile industry — and the government knows it.”

China has seen a boom in economic growth in recent years due to growing trade surpluses with the West, but economists worry that the trade gap will cause longer term global economic problems. China’s textile and apparel exports are the most noteworthy example, with exports up over 1,000 percent in some categories this year and the rapid loss of marketshare and jobs by U.S. textile manufacturers.

Beginning in 1978, the Chinese economy has been transforming from a Soviet-style centrally planned economy to more of a free market style system, under the rigid political control of Communist Party of China.

To this end, the government has leveraged foreign trade to stimulate economic growth. The result has been a fourfold increase in GDP, making China the sixth largest economy in the world. By 2012 the People’s Republic of China may have the highest GDP in the world.

According to U.S. statistics, from 1999 to 2004 China’s trade surplus with the U.S. doubled to $170 billion. Wal-Mart is China’s seventh largest export partner, just ahead of the United Kingdom.

However, the gains from their “socialist market economy” have not been without problems. The Chinese leadership has often experienced the worst results of socialism and capitalism: bureaucracy, lassitude, corruption, and inflation. Inflation rates have been an on-going challenge, reaching as high as 17% in 1995.

Environmental deterioration is a longer-term threat to economic growth. In 1998, the World Health Organization reported that China had seven of the 10 most-polluted cities on Earth. Another concern among some economists is that China’s economy is over-heating, and due to its global economic expansion this could have major repercussions among other nations.

Typically, wages have been low and working conditions poor, with workers living in restrictive dormitories and working at boring factory jobs. However, recent labor shortages have started improving conditions, and raising the minimum wage towards the equivalent of 100-150 US dollars per month. The labor shortages are in part a result of a demographic trend caused by strict family planning.

Kapil Sibal, India’s Minister of Human Resource Development (HRD) held a meeting Monday to present his reform plans for the Indian Institutes of Technology (IIT) sector by increasing the entrance percentage to 80% and above in the class XII (final year) board exams. A three-member committee was set up to review the proposal.

Sibal said, “The present criteria is that students need to secure 60% in class XII for appearing in IIT-JEE. This is not acceptable”, pointing out that the current criteria where students getting more than 60% in the board exam of the twelfth class are eligible for IIT-JEE is not good enough and that it has to be raised to 80-85%.

He also stated that students undervalue final year board exams, preparing instead for the Indian Institute of Technology Joint Entrance Examination (IIT-JEE); they enrol in coaching institutes and concentrate on their study material in order to enter IIT. He wants to abolish these “teaching shops.”

The meeting decided that they would set up two committees, one headed by Anil Kakodkar, Atomic Energy Commission (Chairman) and other by T. Ramasamy, Department of Science and Technology (Secretary). The first committee is scheduled to decide final year board percentage and the second one is scheduled to set the curriculum.

The Kakodkar committee also plans to decide how to abolish coaching institutes and how to move IIT field forward with a greater emphasis on research. The committee is expected to submit its report in the next six months. The minister also clarified that some of these will be implemented from the 2010 academic year and some from 2011.

The meeting was also expected to reduce the fee for African and South Asian Association for Regional Cooperation (SAARC) countries as their fees are higher than those of Indians. The review committee says that people of other countries are tempted to study in India but they refrain due to high fees. The Ramasamy committee is expected to submit its report in the next three months.

Lastly, the meeting said that it will appoint board members and directors on the basis of nominations and independent rank and power to ensure IIT’s activity.

In a study scheduled for publication in the December 1 issue of Forest Ecology and Management, scientists from the University of California, Davis; USDA Forest Service Pacific Southwest Research Station; and University of Washington have found a way to resolve the conflict that has sprung up between protecting forests from increasingly frequent wildfires and droughts and preserving sufficient habitat for the endangered spotted owl, Strix occidentalis. The study was performed in two national parks in California, United States.

For the past twenty-five years, spotted owl habitat preservation has focused on keeping 70% or more of the total ground area covered by natural tree canopy, a tree density that leaves forests prone to wildfires and trees more likely to die during droughts. Both wildfires and droughts have become more frequent in the years since the program began.

However, the previous studies upon which the 70% figure was based only measured overall canopy coverage. In this work, researchers used aerial LiDAR (Light Detection And Ranging) imaging technology to scan areas within Kings Canyon National Park and Sequoia National Park in California. The regions were analyzed by distribution of foliage, tree height, and the sizes of the spaces between trees and stands. These data were then cross-referenced with decades of field studies showing the locations of hundreds of owl nests. They found that spotted owls clustered in areas with very tall trees and stands almost exclusively, over 150 feet (48 m), avoiding areas that only had moderate or low canopy, regardless of how dense or wide.

“This could fundamentally resolve the management problem because it would allow for reducing small tree density, through fire and thinning,” said lead author Malcolm North, of UC Davis and the USDA Pacific Southwest Research Station. “We’ve been losing the large trees, particularly in these extreme wildfire and high drought-mortality events. This is a way to protect more large tree habitat, which is what the owls want, in a way that makes the forest more resilient to these increasing stressors that are becoming more intense with climate change.”

The spotted owl gained national prominence in the United States during the 1990s, when environmentalists’ efforts to preserve its habitat resulted in federal measures forbidding logging on large swaths of land, as well as federal limits on the sales of harvested wood. There was a 1995 U.S. Supreme Court case which was preceded by lawsuits on the part of timber companies and by years of large protests by timber workers and their communities who feared job losses. For a time, it seemed that the spotted owl was also threatened by competition from the faster-breeding barred owl, which had moved west into its territory.

This is not the only major study of spotted owls to reach the public eye this week. On Thursday, the U.S. Fish and Wildlife Service released the California Spotted Owl Conservation Objectives Report, which analyzes the past several decades of research on the California spotted owl and provides recommendations for ecologically and economically viable conservation.
