Chandigarh has got its first pollen calendar. This can identify potential allergy triggers and provide a clear understanding for clinicians as well as allergy sufferers about their causes to help limit their exposure during high pollen loads.

What is Pollen?

Pollen is a fine yellowish powder released by plants. They are essential for the sexual reproduction of flowering plants and plants that produce cones. Each pollen grain contains male gametes necessary for fertilisation.

Pollen and Allergies

Pollen produced by plants are considered major outdoor airborne allergens responsible for allergic rhinitis, asthma, and atopic dermatitis in humans.

In India, about 20-30% of the population suffers from allergic rhinitis/hay fever and approximately 15% develop asthma.

What are Pollen Calendars?

Pollen calendars represent the time dynamics of airborne pollen taxa in graphical form in a particular geographical area.

They yield readily accessible visual details about various airborne pollen taxa present throughout the year, with their seasonality in a single picture. They are also location-specific, with concentrations closely related to locally distributed flora.

What is the significance of Pollen Calendars?

Pollen Calendars will help prepare early advisories and disseminate them through media channels to the citizens so that they can use protective gear during the period when the concentration of allergic pollen will be high.

It is also a preventive tool for sensitive people to diminish exposure when the levels of aero-pollen are high during specific periods

Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970-2019) was released by the World Meteorological Organization (WMO).

About:

• According to the atlas, developed nations incurred the bulk of $3.6tn in economic losses because of severe weather events in past five decades.
• High death tolls in poorer countries have been partly reduced by better evacuation.
• According to scientists of UN’s world meteorological organisation, in past 50 years, number of weather-related disasters had increased fivefold across the globe.
• In this period, death toll of 115 people and more than $200m was lost every day. The death toll was the result of climate change, more extreme weather and improved reporting.
• In this period, total losses amounted to $3.6tn and 2m deaths.
• For instance, estimated cost of Hurricane Ida, fifth-largest hurricane to make landfall in US, could be about $80bn.
• Three out of 10 world’s costliest disasters occurred in 2017 alone namely- hurricanes Harvey (cost-$96.9bn), Maria (cost-$69.4bn) and Irma (cost-$58.2bn).

Wider economic cost

As per catastrophe and risk modelling group AIR, wider economic cost comprises of an estimated hit to insurers of between $17bn and $25bn. This will cover the damage from wind & storm surge and it will pay out to repair cars, residential property, and commercial as well as industrial property. However, it does not include insurance claims that will come from the heavy rains and flooding caused by Ida.

What has led to increase in frequency of extreme weather events?

Frequency and severity of extreme weather events, including wildfires, across southern Europe, Siberia & the US and flooding in northern Europe, has increased due to global warming.

Chandrayaan-2 spacecraft of India has completed more than 9,000 orbits around the Moon. Imaging and other scientific instruments on the aircraft have been providing excellent useful data since then

Lunar Science Workshop 2021

Lunar Science Workshop 2021 is a two-day workshop, organised by Indian Space Research Organisation (ISRO). The workshop started on September 6, 2021. It was organised to commemorate the completion of two years of operation of Chandrayaan-2 spacecraft across the moon’s orbit. The workshop was live-streamed on ISRO’s website and Facebook page to effectively reach the students, academia and institutes.

Two Years of Chandrayaan-2

• According to Chairman of ISRO, K Sivan, Chandrayaan-2 comprises of eight payloads and are conducting remote sensing and in-situ observations of the Moon at 100 km altitude from the lunar surface.
• On the occasion, K Sivan also released data product and science documents besides the data from Chandrayaan-2 orbiter payloads.
• Science data are being made available to academia and institutes in order to analyse them. It will also help in bringing more science from Chandrayaan-2 mission.

Chandrayaan-2 Mission

It is the second lunar exploration mission by the Indian Space Research Organisation (ISRO), after Chandrayaan-1. It comprises of indigenously developed lunar orbiter, Vikram lander and Pragyan lunar rover. Mission was launched with the objective of mapping and study the variations in lunar surface composition, location and abundance of lunar water.

Launch of Chandrayaan-2

Chandrayaan-2 was launched to the Moon on July 22, 2019 by a GSLV Mark III-M1. It reached to the Moon’s orbit on August 20, 2019. It started the orbital positioning manoeuvres to land the Vikram lander. The lander and rover were scheduled to land on near side of the Moon, in the south polar region and conduct research for one lunar day. However, lander crashed after deviating from its intended trajectory. Its successful soft landing would have made India the fourth country to do so following the successful launch of Luna 9 by Soviet Union, Surveyor 1 by United States and Chang’e 3 by China.

• Oceanic shark populations have also decreased by 71% since 1970.

Can we recover their population?

IUCN highlighted that, progress can be made towards reviving tuna populations and other species, if states and other actors take right actions.

IUCN Red List Unit

The red list by IUCN reassesses hundreds of species each year. Out of 138,000 species that were tracked, more than 38,000 are threatened with extinction. Many of the planet’s ecosystems are mainly strained by global warming, deforestation, pollution, habitat degradation and other threats.
