IUCN--International Union for Conservation of Nature

IUCN, the International Union for Conservation of Nature, helps the world find pragmatic solutions to our most pressing environment and development challenges. IUCN was founded in October 1948 as the International Union for the Protection of Nature (or IUPN) following an international conference in Fontainebleau, France. The organization changed its name to the International Union for Conservation of Nature and Natural Resources in 1956 with the acronym IUCN (or UICN in French and Spanish). Use of the name “World Conservation Union”, in conjunction with IUCN, began in 1990. From March 2008 this name is no longer commonly used.

IUCN is the world’s oldest and largest global environmental network - a democratic membership union with more than 1,000 government and NGO member organizations, and almost 11,000 volunteer scientists in more than 160 countries.

IUCN’s work is supported by more than 1,000 professional staff in 60 offices and hundreds of partners in public, NGO and private sectors around the world. The Union’s headquarters are located in Gland, near Geneva, Switzerland

IUCN in the process of assessing freshwater biodiversity of India
The freshwater biodiversity of the country is being assessed by the International Union for Conservation of Nature (IUCN). It is after a gap of 13 years that the freshwater biodiversity of the country, including fish, molluscs, insects and plants, is being assessed using the IUCN Red List Categories and Criteria. The last such assessment was held in 1997.
     The list is considered a comprehensive inventory of the global conservation status of plant and animal species.
It has nine classifications namely extinct, extinct in the wild, critically endangered, endangered, vulnerable, near threatened, least concern, data deficient and not evaluated.
It is estimated that only 13 of the 807 species of freshwater fish found in India have been assessed using the Red list criteria.

India to enlist endangered animal, plant species in Red list

New Delhi, Apr 3 (PTI) In a bid to strengthen its efforts at conservation of endangered plant and animal species, India has decided to initiate the Red listing process on regular basis. A high-level Environment Ministry panel has decided to bring its first report on the country's endangered species -- both plants and animals -- by the end of next year. "To begin with, two documents, one each on 'Red list of Indian Plants' and 'Red list of Indian Animals' would be released during the COP-11 of the Convention on Biological Diversity to be held in New Delhi in October 2012," a Ministry document said. The Red listing process would follow the framework of the International Union for Conservation of Nature (IUCN) regional guidelines and criteria, it said. The document was prepared by the 10-member steering committee, chaired by Jagdish Kishwan, Additional Director General of Forests (Wildlife). Botanical Survey of India (BSI) and Zoological Survey of India (ZSI) would be the focal points for the Red listing of plant and animal species, respectively. The Ministry decided to carry out the Red listing process on a regular basis to end the "paucity of information for the general public on the status, biology and major threats to the endangered species" of the country, which has a staggering variety of flora and fauna. Many organisations are working independently in the country on the Red listing process. The Ministry would provide necessary coordinating mechanism to integrate the efforts of scientific and voluntary organisations into a scientifically acceptable useful output. "The directors of BSI and ZSI would co-opt as many experts -- both individuals and organisations -- as required, to form a core group, each for plants and animal species separately for completion of the Red listing exercise within the stipulated time period," the document said. The Steering Committee would monitor and guide the process of Red listing and the divisions concerned of the Ministry would allocate necessary budgetary provisions for undertaking the exercise. Last month, the Ministry in collaboration with the ZSI, had released a comprehensive document on 'Critically Endangered Animal Species of India'. As per the latest (2011) quantitative evaluation done by the IUCN, there are 57 critically endangered species of animals in India.

Dhamra Port Project

Olive Ridley turtle hatchlings at Rushikulya, Orissa, India in April 2009.
Promoting Corporate Environmental Responsibility in India
The agreement between IUCN and The Dhamra Port Company Limited (DPCL), a joint venture of Tata Steel and Larsen & Toubro, is an encouraging step forward in promoting corporate environmental responsibility. This acquires even greater importance given the proximity of the port in relation to one of the world’s most important mass-nesting beaches for olive ridley turtles. Given the Tata Group’s commitment to environmental preservation, IUCN believes that engaging with DPCL, in an effort to integrate the highest of environmental standards into the port development and operations, is an exemplary model of contemporary conservation in action.

IUCN and DPCL, signed an agreement in 2007 with the aims of:
  • Avoiding, minimizing and mitigating the impacts of Dhamra Port development on turtles and compensating or off-setting any residual impact that cannot be avoided or reasonably mitigated;
  • Improving the project’s performance in other aspects of environment, e.g. terrestrial environment as affected by the access roads, railway lines and other secondary developments; and
  • Contributing to raising national and global standards for environmentally responsible development of mega projects.
Current initiatives

In addition of serving as secretariat of IUCN India National Committee, the current activities of India programme include:

The Livelihoods and Landscapes Strategy (LLS) is a leverage programme to catalyze the sustainable use and conservation of forest biodiversity and ecosystem services for the benefit of the rural poor.

Mangroves for the Future (MFF ) initiative, which will address long term threats to coastal ecosystems and livelihoods and which will promote investment in conserving coastal ecosystems as development ‘infrastructure’.

The IUCN Red List of Threatened Species  provides taxonomic, conservation status and distribution information on plants and animals that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those plants and animals that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable). The IUCN Red List also includes information on plants and animals that are categorized as Extinct or Extinct in the Wild; on taxa that cannot be evaluated because of insufficient information (i.e., are Data Deficient); and on plants and animals that are either close to meeting the threatened thresholds or that would be threatened were it not for an ongoing taxon-specific conservation programme (i.e., are Near Threatened).
IUCN Red List categories

IUCN Protected Area Categories System

Through its World Commission on Protected Areas (WCPA), IUCN have developed seven Protected Area Management Categories that define protected areas according to their management objectives and are internationally recognised by various national governments and the United Nations.

The categories provide international standards for comparing the protected areas in different countries and encourage the planning of protected areas under management aims. 

The categories are:

Ia----- Strict Nature Reserve; 
Ib----- Wilderness Area;
II------ National Park; 
III----- Natural Monument of Feature; 
IV----- Habitat/Species Management Area; 
V----- Protected Landscape/ Seascape and; 
VI---- Protected area with sustainable use of natural resources

Blackburn, 2 others share Nobel Medicine



STOCKHOLM: Americans Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak on Monday won the 2009 Nobel Prize in Medicine for discovering a key mechanism in the genetic operations of cells, an insight that has inspired new lines of research into cancer. 

It was the first time two women have been among the winners of the Prize. The trio solved the mystery of how chromosomes, the rod-like structures that carry DNA, protect themselves from degrading when cells divide. The Nobel citation said the laureates found the solution in the ends of the chromosomes — features called telomeres that are often compared to the plastic tips at the end of shoe laces that keep those laces from unravelling.

Dr. Blackburn and Dr. Greider discovered the enzyme that builds telomeres — telomerase — and the mechanism by which it adds DNA to the tips of chromosomes to replace genetic material that has eroded away.

The prize-winners’ work, done in the late 1970s and 1980s, set the stage for research suggesting that cancer cells use telomerase to sustain their uncontrolled growth

Habitable moons 'could to be spotted by 2014

British astronomers have claimed that thousands of moons capable of supporting life, like those shown in the popular Star Wars' flicks, could be scattered all over our galaxy, and are likely to be spotted by 2014.
 
A team at University College London hopes to track the habitable moons within the next five years, using a telescope launched by US space agency Nasa earlier this year to hunt out other planets.

According to lead astronomer Dr David Kipping, there are more than 12,500 stars within sight of Nasa's Kepler Space Telescope that have the potential for moons orbiting in areas of space where conditions could be favourable to life.

In fact, they have devised a new method for detecting moons in other solar systems -- known as exomoons.

एड्स के ख़िलाफ़ अहम सफलता


वैज्ञानिकों का कहना है कि उन्होंने एक ऐसा टीका बना लिया है जो एड्स फैलानेवाले वायरस एचआईवी के ख़तरे को तीस प्रतिशत कम कर देगा.
थाईलैंड में अपनी इच्छा से आगे आए सोलह हज़ार लोगों पर इस टीके का परीक्षण किया गया है और इस पूरे कार्यक्रम के लिए पैसा अमरीकी सेना की तरफ़ से दिया गया.

एड्स के क्षेत्र में काम करनेवाले कई जानकारों ने इसे एक ऐतिहासिक मील का पत्थर बताया है.

वैसे तो ये टीका फ़ौरन ही दुकानों या अस्पतालों में पहुंच जाएगा ऐसा होता हुआ नहीं दिख रहा लेकिन इतने ज़्यादा लोगों पर पहली बार इस तरह का परीक्षण हुआ है और पहली बार सही मायने में उम्मीद जगी है कि एड्स का एक संपूर्ण टीका बनाया जा सकता है.

पूरी दुनिया में तीन करोड़ तीस लाख लोग एचआईवी से ग्रस्त हैं.

अबतक दवाओं से लोगों को कुछ राहत मिली है लेकिन पहली बार एक टीका बना है जो इसे रोक सके.
यहां तक पहुंचने में भी वैज्ञानिकों को सात साल लगे हैं.
वैसे तो इसकी शब्दावली काफ़ी जटिल है लेकिन आसान ज़ुबान में यही कहा जा सकता है कि ये टीका एचआईवी के संक्रमण के ख़तरे को कम करने में 31.2 प्रतिशत कारगर है.
थाईलैंड में हुए एक संवाददाता सम्मेलन में कहा गया कि ये टीका पूरी तरह कारगर तो नहीं है लेकिन सही दिशा में उठाया गया एक महत्वपूर्ण कदम है.
लैंसेट मेडिकल जरनल के संपादक डॉ रिचर्ड हर्टन कि इस टीके की खोज काफ़ी उत्साहजनक है और इससे कुछ शंकाओं के साथ ही सही लेकिन उम्मीद बढ़ती है.
इस टीके से दुनिया भर में चल रहे उन शोधों को भी मदद मिलेगी जहां कोशिशें चल रही हैं एक पूरी तरह से कारगर टीका बनाने की.

Scientists devise wire-free heart pump

 
Scientists have created what they claim is a wireless heart pump, thereby avoiding the need for infectionprone power cables running through the chest and eventually offering an alternative to heart transplants.
Previous heart pumps needed wires through the chest to get their power which was a source of serious infection in as many as 40 per cent of patients. Now, an international team has come up with a technology to power a wireless heart pump.

According to the scientists, the wireless heart pump uses magnetic fields to transfer power through a person's skin rather than using wire cables. The pump can be powered this way 24 hours a day for a person's lifetime. The scientists, led by Auckland University, have now floated a new company, TETCor, to take the technology to market for powering a wide range of devices implanted in human body.

According to TETCor CEO, Dr Simon Malpas, heart pumps need a huge amount of power. And the only way to power current artificial heart pumps is through a wire cable that goes via a patient's stomach and chest.
He said these wires cause serious infections, often leading to death in about 40 per cent of patients.

"This new wireless heart pump weights only 92 grams and measures just seven centimetres by three centimetres. It uses a coil outside a person's body to generate a magnetic field. A second coil placed inside a person's body, near the collar bone, picks up the signal from this field and creates power for the pump," Dr Malpas said. Dr Malpas said previous attempts at making wireless heart pumps produced too much heat. These earlier pumps would have ended up "cooking a person from the inside".

"The secret of this new technology is to deliver exactly the right amount of power, thereby eliminating the heating problem."

1ST ROCKY EXTRASOLAR PLANET FOUND

Astronomers have finally found a place outside our solar system where there's a firm place to stand -- if only it weren't so broiling hot.

As scientists search the skies for life elsewhere, they have found more than 300 planets outside our solar system. But they all have been gas balls or can't be proven to be solid.

Now a team of European astronomers has confirmed the first rocky extrasolar planet. Scientists have long figured that if life begins on a planet, it needs a solid surface to rest on, so finding one elsewhere is a big deal.
"We basically live on a rock ourselves," said co-discoverer Artie Hartzes, director of the Thuringer observatory in Germany. "It's as close to something like the earth that we've found so far. It's just a little too close to its sun."

So close that its surface temperature is more than 3,600 degrees Fahrenheit, too toasty to sustain life. It circles its star in just 20 hours, zipping around at 466,000 mph. By comparison, Mercury, the planet nearest our sun, completes its solar orbit in 88 days.

"It's hot, they're calling it the lava planet," Mr Hartzes said. This is a major discovery in the field of trying to find life elsewhere in the universe, said outside expert Alan Boss of the Carnegie Institution.

Australia in list of countries with high carbon emissions; India figures in list

Australia’s economy is the worst-placed in the rich world to stay competitive when global efforts to curb climate change force a price on carbon-dioxide emissions, a report released on Monday found.
Australia ranked 15th in its ability to generate business in a low-carbon world, according to an analysis commissioned by London-based think tank E3G and Sydney’s The Climate Institute.
Only South Africa, India, Saudi Arabia and Indonesia had lower rankings. France, Japan, Britain, South Korea and Germany ranked highest for carbon competitiveness, because of their energy efficiency measures and their shift from reliance on coal for power generation.
In a preface to the report, economist and climate campaigner Lord Nicholas Stern said the global economic downturn provided an opportunity for countries like Australia to improve energy efficiency.
Countries which don’t seize this opportunity will undermine their future competitiveness,” Mr. Stern said. Climate Institute head John Connor said that Australia had more work to do than any other nation to decouple economic growth from carbon emissions.
We’re coming at the back of the pack in terms of how efficient our economies are and how we can be helping towards a global agreement,” he said. “This is something which puts our jobs and living standards at risk if we don’t get on with economy-wide measures to change our economy to cut carbon pollution and to increase our productivity.” Australians are the world’s worst carbon-dioxide polluters per capita, according to the British risk assessment company Maplecroft Ltd. The United States, Canada, the Netherlands and Saudi Arabia round out the top five emitters of greenhouse gases from fossil fuels in the per capita list Maplecroft released last week.
Australia has an average output of 20.5 tons of carbon dioxide per person per year, compared with 19.7 tons for the US, 4.5 tons for China and just 1.1 tons for India.

India - US Nuke agreement - update


Visiting U.S. Secretary of State will be the unveiling of a new strategic dialogue architecture and the signing of an agreement to facilitate the launch of U.S. satellites and satellites with U.S. components on Indian launch vehicles.

The new dialogue architecture is intended to take Indo-U.S. relations to a higher level, 3.0 — to use Ms. Clinton’s phrase — and will cover areas like nonproliferation, security, education, health and development.

The new Technology Safeguards Agreement (TSA) to be signed will cover launches involving satellites owned by U.S. government or academic institutions or by third country space agencies and universities which have U.S. equipment on board. Since the components and satellites will have to be integrated with ISRO’s launch vehicles, the TSA will provide for monitoring by the U.S. side to ensure against diversion or misuse of equipment.


The agreement to be signed will be an umbrella one — similar to the TSA that China and the U.S. signed — with individual licensing by the State Department likely dispensed with, but India will not yet be able to enter the lucrative market for the launch of U.S. commercial satellites or third country commercial satellites with U.S. components till a separate Commercial Space Launch Agreement (CSLA) is signed.

A second agreement will also be signed on a framework for “robust result-oriented cooperation” in science and technology for “collaborative research and its commercialisation.”This agreement will build on the October 2005 Science and Technology Cooperation Agreement.

New material for nano-scale computer chips

Nano-chemists from the Chinese Academy of Sciences and Nano-Science Centre, Department of Chemistry at University of Copenhagen have developed nano-scale electric contacts out of organic and inorganic nano-wires. In the contact they have crossed the wires like Mikado sticks and coupled several contacts together in an electric circuit. In this way they have produced prototype computer electronics on the nano-scale, according to a press release.

Alternative to silicon computers

Today the foundation of our computers, mobile phones and other electronic apparatus is silicon transistors. A transistor is in principal an on- and off- contact and there are millions of tiny transistors on every computer chip. However, we are reaching the limit for how small we can make transistors out of silicon.

We already use various organic materials in, for example, flat screens, such as OLED (Organic Light Emitting Diode). The new results show how small and advanced devices made of organic materials can become.

Thomas Bjørnholm, Director of the Nano-Science Center, Department of Chemistry at University of Copenhagen explains:

We have succeeded in placing several transistors consisting of nanowires together on a nano device. It is a first step towards realisation of future electronic circuitry based on organic materials – a possible substitute for today's silicon-based technologies. This offers the possibility of making computers in different ways in the future.

Danish-Chinese nanoelectronics

The researchers have used organic nanowires combined with the tin oxide nanowires in a so-called hybrid circuit. As in a Mikado game, the nanowires cross in a device consisting of 4-6 active transistor moieties. The devices have a low operational current, high mobility and good stability and that is essential in order for the material to be able to compete with silicon.

Professor Wenping Hu, Chinese Academy of Sciences is excited over the results:

This work is the first significant result of our collaboration with the researchers from the Nano-Science Center. It is a good starting point for our new Danish-Chinese research centre for molecular nano-electronics and it underlines the fact that we can complement each other and that together we can achieve exciting and important results.
