  • The Crisis In The Middle East

    What’s behind the Armenia-Azerbaijan clashes?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Causacus region mapping

    Mains level: Usual crisis in the middle east and caucasus region

    Fresh clashes erupted on the Armenia-Azerbaijan border, threatening to push the countries back to war 26 years after a ceasefire was reached.

    Try this PYQ:

    Q.Turkey is located between-

    (a) The Black Sea and Caspian Sea

    (b) The Black Sea and Mediterranean Sea

    (c) Gulf of Suez and the Mediterranean Sea

    (d) Gulf of Aqaba and the Dead Sea

    The conflict

    • The largely mountainous and forested Nagorno-Karabakh, home for some 150,000 people, is at the centre of the conflict.
    • Nagorno-Karabakh is located within Azerbaijan but is populated, mostly, by those of Armenian ethnicity (and mostly Christian compared to the Shia Muslim majority Azerbaijan).
    • The conflict can be traced back to the pre-Soviet era when the region was at the meeting point of Ottoman, Russian and the Persian empires.

    A legacy of soviet era

    • Once Azerbaijan and Armenia became Soviet Republics in 1921, Moscow gave Nagorno-Karabakh to Azerbaijan but offered autonomy to the contested region.
    • In the 1980s, when the Soviet power was receding, separatist currents picked up in Nagorno-Karabakh.
    • In 1988, the national assembly voted to dissolve the region’s autonomous status and join Armenia.
    • But Baku suppressed such calls, which led to a military conflict.
    • When Armenia and Azerbaijan became independent countries after the collapse of the Soviet Union in 1991, the clashes led to an open war in which tens of thousands of people were killed.
    • The war lasted till 1994 when both sides reached a ceasefire (they are yet to sign a peace treaty and the border is not clearly demarcated).

    Issue over control

    • By that time, Armenia had taken control of Nagorno-Karabakh and handed it to Armenian rebels. The rebels have declared independence, but have not won recognition from any country.
    • The region is still treated as a part of Azerbaijan by the international community, and Baku wants to take it back.

    What is the strategic significance of the region?

    • The energy-rich Azerbaijan has built several gas and oil pipelines across the Caucasus (the region between the Black Sea and the Caspian Sea) to Turkey and Europe.
    • This includes the Baku-Tblisi-Ceyhan oil pipeline (with a capacity of transporting 1.2 billion barrels a day), the Western Route Export oil pipeline, the Trans-Anatolian gas pipeline and the South Caucasus gas pipeline.
    • Some of these pipelines pass close to the conflict zone (within 16 km of the border). In an open war between the two countries, the pipelines could be targeted, which would impact energy supplies.

    What’s Turkey’s role?

    • Turkey has historically supported Azerbaijan and has had a troublesome relationship with Armenia.
    • In the 1990s, during the war, Turkey closed its border with Armenia and it has no diplomatic relations with the country.
    • The main point of contention between the two was Ankara’s refusal to recognise the 1915 Armenian genocide in which the Ottomans killed some 1.5 million Armenians.
    • On the other end, the Azeris and Turks share strong cultural and historical links. Azerbaijanis are a Turkic ethnic group and their language is from the Turkic family.

    Where does Russia stand?

    • Moscow sees the Caucasus and Central Asian region as its backyard. But the current clashes put President Vladimir Putin in a difficult spot.
    • Russia enjoys good ties with both Azerbaijan and Armenia and supplies weapons to both.
    • But Armenia is more dependent on Russia than the energy-rich, ambitious Azerbaijan. Russia also has a military base in Armenia.
    • But Moscow, at least publicly, is trying to strike a balance between the two. Like in the 1990s, its best interest would be in mediating a ceasefire between the warring sides.

    Cat Que Virus

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Cat Que Virus

    Mains level: Not Much

    In a study published in the Indian Journal of Medical Research, scientists have noted the presence of antibodies against the Cat Que virus (CQV) in two human serum samples.

    Try this PYQ:

    Q.Which one of the following statements is not correct?

    (a) Hepatitis B virus is transmitted much like HIV.

    (b) Hepatitis B, unlike Hepatitis C, does not have a vaccine.

    (c) Globally, the number of people infected with Hepatitis B and C viruses is several times more than those infected with HIV.

    (d) Some of those infected with Hepatitis B and C viruses do not show the symptoms for many years.

    What is the Cat Que Virus?

    • For CQV, domestic pigs are considered to be the primary mammalian hosts.
    • Antibodies against the virus indicate that the virus has formed a “natural cycle” in the local area and has the ability to spread in pigs and other animal populations through mosquitoes.
    • CQV belongs to the Simbu serogroup and infects both humans and economically important livestock species.
    • It was first isolated in 2004 from mosquitoes during the surveillance of arbovirus activity in northern Vietnam.
    • In this study, researchers reported a CQV strain (SC0806), which was isolated from mosquito samples collected in China in 2006 and 2008.

    Impact on humans

    • Humans can get infected through mosquitoes as well.
    • In the study, scientists note that because of positivity in human serum samples and the replication capability of CQV in mosquitoes, there is only a “possible disease-causing potential” of CQV in the Indian scenario.

    (a) Social justice and empowerment

    (b) Inclusive Growth

    (c) Globalization

    (d) Carrying capacity

    What are the ESG funds?

    • ESG means using Environmental, Social and Governance factors to evaluate companies and countries on how far advanced they are with sustainability.
    • ESG investing is used synonymously with sustainable investing or socially responsible investing.
    • While selecting a stock for investment, the ESG fund shortlists companies that score high on the environment, social responsibility and corporate governance, and then looks into financial factors.
    • So, the scheme focuses on companies with environment-friendly practices, ethical business practices and an employee-friendly record.
    • They imbibe the environment, social responsibility and corporate governance in their investing process.

    Why so much focus on ESG now?

    • Modern investors are re-evaluating traditional approaches and look at the impact their investment has on the planet.
    • As a result of this paradigm change, asset managers have started incorporating ESG factors into investment practices.
    • Companies with good ESG scores tick most of the checkboxes for investing, tend to mitigate environmental and social risks and tends to have stronger cash flows, lower borrowing costs and durable returns.
