Pusa-2090, a high-yielding short-duration paddy variety developed by IARI

The Indian Agricultural Research Institute in Delhi has successfully developed a high-yielding short-duration paddy variety called Pusa-2090.

  1. Purpose of Development: The new variety aims to address challenges associated with paddy stubble burning and air pollution in the Delhi-NCR region.
  2. Stubble Burning Issue: The traditional paddy crop, transplanted in June, is usually ready for harvest by late October, leaving farmers with minimal time to prepare fields for the next wheat crop. Stubble burning has been a common practice due to this time constraint.
  3. Comparison with Existing Variety: Pusa-2090 is an improved version of the existing Pusa-44 variety. The new variety matures in 120 to 125 days, providing farmers with approximately 30 more days compared to Pusa-44, which takes 155 to 160 days to mature.
  4. Advantages of Pusa-2090: The shortened maturity period of Pusa-2090 allows farmers more time to ready their fields for the subsequent crop, reducing the reliance on stubble burning.

Q.: How does the maturity period of Pusa-2090 compare to the existing Pusa-44 paddy variety?

a. Pusa-2090 takes longer to mature
b. Pusa-2090 and Pusa-44 have similar maturity periods
c. Pusa-2090 matures faster than Pusa-44
d. None of the above

Ans : c. Pusa-2090 matures faster than Pusa-44

Q.: Why do farmers in the Delhi-NCR region resort to burning paddy stubble?

a. Tradition and cultural practices
b. Lack of awareness
c. Short time between paddy harvest and sowing wheat
d. Soil enrichment

Ans : c. Short time between paddy harvest and sowing wheat

Eco-Friendly ‘Bahu Balli’ Bamboo Barriers to replace Steel barriers on Highways

The government plans to replace steel barriers on highways with special ‘Bahu Balli’ barriers made of Bamboo. Union Road Transport Minister Nitin Gadkari revealed that a pilot project using bamboo barriers has already started in Chhattisgarh and will soon be implemented in other states.

  1. The decision to use bamboo barriers is driven by their eco-friendliness and the potential to boost the bamboo industry and create employment opportunities in the north-eastern regions and tribal areas.
  2. These bamboo barriers will also be utilized in access control areas on highways to prevent the entry of pedestrians, animals, and vehicles onto the Expressway.
  3. The current standards for Expressways and green-field access controlled National Highways involve the use of mild steel sections and welded steel wire mesh for fencing. However, guidelines issued by the Ministry propose the adoption of precast concrete boundary walls in these areas.
  4. A proposal has been received and an order placed for the feasibility and demonstration of the ‘Bahu Balli Fences,’ made of bamboo, as an alternative to the traditional barriers.

Question: What material will be used to replace steel barriers on highways according to the government’s plan?

A) Concrete
B) Wood
C) Bamboo
D) Plastic

Answer: C) Bamboo

Heatwaves and Extreme weather have affected most parts of the world

The United Nations’s World Meteorological Organization (WMO) has warned that heatwaves and extreme weather have affected most parts of the world, including Europe, the US, and Asia.

  • Sardinia in Italy could see temperatures of more than 47 degrees Celsius, and several Italian cities could reach 40 degrees.
  • Heatwaves this summer have coincided with wildfires and deadly flooding in various parts of the world.
  • The WMO has warned that the world needs to prepare for increasingly intense heatwaves and that the current heatwave in the northern hemisphere is set to intensify.
  • Temperatures in North America, Asia, North Africa, and the Mediterranean are expected to be above 40 degrees Celsius for a prolonged period this week.
  • Overnight minimum temperatures are also expected to reach new highs, increasing the risk of heart attacks and deaths.

Q.: Which organization issued a warning about the impact of heatwaves and extreme weather worldwide?
a) World Health Organization (WHO)
b) World Meteorological Organization (WMO)
c) United Nations Environment Programme (UNEP)
d) International Panel on Climate Change (IPCC)

Peru Declares State of Emergency around Ubinas Volcano; Part of the “Ring of Fire”

Peru has declared a state of emergency for sixty days in areas surrounding the Ubinas volcano. The volcano has been emitting ash and gas since earlier in the week, as reported by the Geophysical Institute of Peru.

The smoke cloud from the volcano has reached towns located 10 kilometers away from the volcano. Approximately 2,000 people reside in the affected areas. The region where Ubinas is located, Moquegua, is 1,200 kilometers southeast of the capital city Lima.

Ubinas is the most active volcano in Peru and is situated in a region known for volcanic activity and earthquakes, called the “Ring of Fire” along the edges of the Pacific Ocean.

What is “Ring of Fire”

The “Ring of Fire” is a horseshoe-shaped area around the Pacific Ocean known for frequent earthquakes and volcanic activity. It stretches for approximately 40,000 kilometers and includes countries such as Chile, Japan, the Philippines, Indonesia, and the western coast of the United States. The region experiences a high concentration of earthquakes and is home to many active volcanoes. It poses risks to the populations living in these areas, including the potential for tsunamis.

Q.: The “Ring of Fire” is known for:
a) High precipitation levels
b) Frequent earthquakes and volcanic activity
c) Rich biodiversity
d) Historical cultural sites

Answer: b) Frequent earthquakes and volcanic activity

World’s hottest day : 3 July 2023, El Niño Weather Pattern to Blame

The U.S. National Centers for Environmental Prediction has reported that 3 July 2023 marked the World’s hottest day ever recorded globally. The average global temperature reached 17.01 degrees Celsius, surpassing the previous record set in August 2016. The heatwaves experienced around the world have been attributed to the El Niño weather pattern.

In the United States, an intense heat dome has caused extreme weather conditions in recent weeks. China has also been grappling with a persistent heatwave, with temperatures exceeding 35 degrees Celsius. North Africa has witnessed temperatures nearing 50 degrees Celsius, while the Middle East has experienced unusually scorching heat during the Hajj pilgrimage in Saudi Arabia.

Even Antarctica, in its winter season, has recorded abnormally high temperatures. Ukraine’s Vernadsky research base on the Argentine Islands in Antarctica recently broke its July temperature record with a reading of 8.7 degrees Celsius. Scientists have expressed concern about the climate crisis, which has been exacerbated by the El Niño weather pattern. The United Nations’ World Meteorological Organization (WMO) issued a warning this week about the onset of the latest El Niño event.

Q.: Which day was recorded as the World’s hottest day according to data from the U.S. National Centers for Environmental Prediction?

A) 5 August 2016
B) 3 July 2023
C) 21 August 2022
D) 22 June 2019

Answer: B) 3 July 2023

India to launch heat index to quantify heat hazard, generate impact-based heat wave alerts for specific locations

India will launch its own heat index next year to quantify the impact of heat on its population and generate impact-based heatwave alerts for specific locations.

The India Meteorological Department (IMD) began issuing an experimental heat index last week, taking into account air temperature and relative humidity to determine how hot it really feels.

The new heat index will integrate other parameters such as wind and duration of exposure to provide an effective indicator of heat stress for people.

The hazard score for the heat index will be ready in around two months, and it will be operational in the next summer season.

Question : What is the purpose of India launching its own heat index?
a) To quantify the impact of heat on the environment
b) To generate impact-based heatwave alerts for specific locations
c) To predict natural disasters
d) To measure air pollution levels

Answer: b) To generate impact-based heatwave alerts for specific locations
