Why in News?

Recently, the Food and Agriculture Organisation (FAO) of the United Nations has launched the Asia-Pacific Regional Overview of Food Security and Nutrition 2023: Statistics and Trends, which said 74.1% of Indians were unable to afford a healthy diet in 2021.

What are the Key Highlights of the Report?

  • Global:
    • The prevalence of undernourishment in the Asia and the Pacific region decreased to 8.4% in 2022 from 8.8% of the previous year, equivalent to around 12 million fewer undernourished people than in 2021, but 55 million more than in 2019, prior to the Covid-19 pandemic.
    • With 370.7 million undernourished people, the Asia and the Pacific region represents half of the world’s undernourished people.
    • Southern Asia accounts for almost 314 million of the region’s undernourished people. This represents 85 % of undernourished people in the Asia and the Pacific region.
    • There are more severely food insecure individuals in Southern Asia than any other subregions.
    • Women across the subregions, except for Eastern Asia, tend to be more food insecure than men.
  • Indian:
    • Inability to Afford Healthy Diet: 74.1% of Indians were unable to afford a healthy diet in 2021, in 2020, the percentage was 76.2.
      • Comparison with Neighboring Countries: Pakistan had 82.2% and Bangladesh had 66.1% of their populations facing difficulties in accessing healthy food.
    • Regional Nutrition and Food Security: 16.6% of India's population is undernourished.
      • India has a lower prevalence of moderate or severe and severe Food Insecurity compared to the world since 2015.
    • Children's Health: Stunting affected 31.7% of children under five, while wasting (low weight for height) was prevalent in 18.7% of children under five.
      • The WHO global nutrition target for childhood wasting is less than 5%.
      • Stunted growth and development are the result of poor maternal health and nutrition, inadequate infant and young child feeding practices, and repeated infections interacting with a variety of other factors over a sustained period.
    • Women's Health: 53% of the country’s women aged between 15 to 49 had anaemia, which was the largest prevalence rate in India in 2019.
      • Anaemia impairs health and well-being in women and increases the risk for adverse maternal and neonatal outcomes.
    • Obesity and Nutrition Indicators: 1.6% of the country’s adults are obese as of 2000, according to the FAO. The figure has increased to 3.9% by 2016.
    • Exclusive Breastfeeding: On exclusive breastfeeding among infants 0–5 months of age, India has improved the prevalence with a percentage of 63.7%, which is higher than the world prevalence – 47.7%.
      • India has the highest prevalence of low birthweight in the region (27.4%), followed by Bangladesh and Nepal.

India's Coal Plants: SO2 Emission Control

For Prelims: Centre for Research on Energy and Clean Air (CREA), Sulfur Dioxide (SO2), Flue Gas Desulfurization (FGD), Circulating Fluidised Bed Combustion (CFBC), Greenpeace, Coal, Oil, Natural Gas

For Mains: The Environmental Consequences of Measures to Mitigate SO2 Emissions

Source: DTE

Why in News?

Recently, an analysis by the Centre for Research on Energy and Clean Air (CREA) has found less than 8% of India’s coal-based power plants have installed the SO2 emission reduction technology recommended by the Union Ministry of Environment, Forest and Climate Change (MoEF&CC) to keep Sulfur Dioxide (SO2) emissions in check.

  • According to a 2019 Greenpeace study, India is the largest emitter of SO2 in the world.

What are the Technologies to Reduce SO2 Emissions?

  • Flue Gas Desulfurization (FGD):
    • FGD is the process of removing sulphur compounds from the exhaust emissions of fossil-fueled power stations.
    • This is done through the addition of absorbents, which can remove up to 95% of the sulphur dioxide from the flue gas.
    • Flue gas is the material emitted when fossil fuels such as coal, oil, natural gas, or wood are burned for heat or power.
  • Circulating Fluidized Bed Combustion (CFBC):
    • CFBC Boiler is an environment-friendly power facility to reduce the discharge of pollutants such as nitrogen oxide and sulphur oxide by injecting air and lime at the same time for burning.
    • A bed of solid particles is said to be fluidized when the pressurised fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions. Fluidization causes the transformation of the state of solid particles from static to dynamic.

What are the Key Findings of the Study?

  • Only a combined capacity of 16.5 Gigawatts(GW) of coal plants have installed FGDs and Circulating Fluidised Bed Combustion (CFBC) boilers equivalent to 5.9 GW across India.
  • The CREA analysis found that 92 % of the country’s coal power plants function without FGDs.
  • Blanket extension of the deadline for all coal power plants without checking on their progress by MoEF&CC and Central Pollution Control Board (CPCB) played a major role in derailment of emission controls from coal-based electricity generation units.
    • The MoEF&CC introduced emission standards in 2015 for regulating PM, SO2, NOx, and Hg (Mercury) emissions.
    • The deadline has been extended four times for units in Delhi and the National Capital Region (NCR) and three times for most other units across the country.
  • India’s energy generation installed capacity stands at 425 GW. The thermal sector holds a predominant position within the overall installed capacity, encompassing coal (48.6%), gas (5.9%), lignite (1.6%) and a minimal share (<0.2%) from diesel.

What is the Categorisation of Power Plants for Installing FGD?

  • In 2021, the MoEF&CC divided the categories of coal-power plants based on geography to enforce deadlines.
    • Category A is demarcated to coal-based power plants within a 10-kilometer radius of the National Capital Region (NCR) and of cities with a million-plus population.
    • Category B is within a 10 km radius of critically polluted areas or non-attainment cities.
    • Category C is the remaining plants throughout the country.
      • The majority of the country’s power plants belong to Category C, with the longest deadlines.

Centre for Research on Energy and Clean Air (CREA)

  • CREA is an independent research organisation focused on revealing the trends, causes, and health impacts, as well as the solutions to air pollution.
  • It uses scientific data, research and evidence to support the efforts of governments, companies and campaigning organisations worldwide in their efforts to move towards clean energy and clean air.

Way Forward

  • Accelerate FGD Implementation:
    • Prioritise and expedite the installation of FGD technology in coal-based power plants. Encourage and incentivize the adoption of this technology to ensure compliance with emission standards set by the MoEF&CC.
  • Expand CFBC Implementation:
    • Provide support and incentives for power plants to adopt CFBC technology, aiming for a broader implementation to enhance environmental sustainability.
  • Stricter Enforcement and Monitoring:
    • Strengthen regulatory mechanisms for monitoring and enforcing emission standards. Implement strict penalties for non-compliance with deadlines and emission regulations.
  • Research and Development (R&D):
    • Invest in research and development to explore and implement advanced technologies that go beyond current standards. Foster innovation in clean energy solutions and emission control technologies to make coal-based power generation more sustainable.

India Imposes Onion Export Ban

For Prelims: India Imposes Onion Export Ban, Director General of Foreign Trade (DGFT), Rabi and Kharif Season, Food Security.

For Mains: India Imposes Onion Export Ban, Current Scenario of Wheat Distribution Across India.

Source: IE

Why in News?

Recently, the Director General of Foreign Trade (DGFT) has announced a ban on onion exports until March 2024, issuing a notification converting the export policy of onions from 'Free' to 'Prohibited'.

  • The current supply shortage, caused by early depletion of 2022-23 rabi season stocks and anticipated lower kharif 2023 output, along with increased festive demand, has led to a significant rise in onion prices.
  • The government has also revised the stock limit for wheat, the stock limit has been halved to 1,000 tonnes for wholesalers, and for retailers to 5 tonnes.

Why has the Government Banned Export of Onion Price?

  • Price Control:
    • By restricting onion exports, the government aims to prevent price surges or fluctuations within the domestic market.
      • To combat spiraling prices, the Centre had imposed a Minimum Export Price of USD 800 per tonne on onions in October 2023. Earlier, in August, the government imposed a 40% export duty on onions.
    • Onions have a history of significant price volatility, and an export ban helps in stabilizing prices, making them more affordable for local consumers.
  • Addressing Scarcity:
    • Factors like adverse weather conditions, lower production, or increased demand can lead to a scarcity of onions within the country.
    • By banning exports, the government ensures that the available supply is directed towards meeting domestic demands first.
  • Food Security:
    • Onions are a staple in Indian cuisine, and any scarcity can impact food security. By curbing exports, the government ensures that the population has access to this essential food item without facing shortages or unaffordable prices.

What are the Key Facts About Onion?

  • Onion is an important horticultural commodities grown worldwide for their culinary purposes and medicinal values.
  • India is the second largest producer of onion after China.
  • Maharashtra, Karnataka, Orissa, Uttar Pradesh, Gujarat, Andhra Pradesh and Tamil Nadu are the major onion producing states.
  • Maharashtra ranks first in Onion production with a share of 42.53% followed by Madhya Pradesh with a share of 15.16% in 2021-22 (3rd Advance Estimate).

Why has the Government Put Stock Limits on Wheat?

  • The revised stock limits aim to prevent hoarding practices by entities involved in wheat stocking. By imposing stricter limits, the government intends to discourage artificial scarcity and ensure a fair distribution of wheat across various stakeholders.
  • Excessive hoarding can lead to an imbalance between supply and demand, causing price fluctuations that may negatively impact consumers.
  • Regulating wheat stocks ensures that sufficient quantities remain available in the market to meet the country's food requirements. It helps maintain food security by preventing shortages and ensuring access to this staple food item for consumers.

What is the Current Scenario of Wheat Distribution Across the Country?

  • India is the world's second-biggest wheat producer after China. But it accounts for less than 1% of the global wheat trade. It keeps a lot of it to provide subsidised food for the poor.
  • Major wheat-growing states in India are Uttar Pradesh, Punjab, Haryana, Madhya Pradesh, Rajasthan, Bihar and Gujarat.
  • Major Export Destinations (2022-23): Bangladesh, Indonesia, Korea Rep., United Arab Emts and Yemen Republic.

Saiga Antelope

Source: DTE

Why in News?

The International Union for Conservation of Nature (IUCN) Red List has recently reclassified the status of the Saiga Antelope (Saiga tatarica) from Critically Endangered to Near Threatened.

  • This significant update reflects positive conservation efforts and offers a hopeful outlook for the survival of the Saiga antelope species.

What are the Key Facts about Saiga Antelope?

  • About:
    • The saiga antelope is a large, nomadic, migratory herbivore that lives across the Eurasian Steppe.
      • It's found in Kazakhstan, Mongolia, the Russian Federation, Turkmenistan, and Uzbekistan.
    • It belongs to the family of Bovidae(order Artiodactyla).
    • The Saiga has two subspecies: Saiga tatarica tatarica (found in most of the range) and Saiga tatarica mongolica (found only in Mongolia).
    • Typical habitat consists of flat open areas covered with low-growing vegetation, allowing animals to run quickly.
    • They have an unusual hanging nose, which makes them look like a camel, although they are goat-sized, and male saigas have horns.

  • Decline in Saiga Population:
    • The Saiga, which has roamed the earth since the last Ice Age, faced a drastic decline in its population by more than 95% within a decade after the collapse of the Soviet Union in 1991.
    • The decline was primarily due to poaching for the species' meat and horn. The horn is used in Chinese Traditional Medicine.
    • In 2015, a major epidemic killed more than 200,000 animals, which was a blow to the species' promising recovery.
  • Conservation:
    • Conservation efforts have led to a positive change in the global Red List status of the Saiga antelope.
      • Kazakhstan has shown commendable leadership in species recovery, implementing anti-poaching initiatives, law enforcement measures, and establishing State Protected Areas.
      • The Convention on the Conservation of Migratory Species of Wild Animals (CMS) has facilitated cooperation among governments and civil society organizations for the conservation of the Saiga antelope.
    • The Saiga antelope population has soared to over 1.9 million, with the Mongolian subspecies witnessing a notable increase, reaching 15,540 individuals in the 2023 census.

Turbulence

Turbulence, often encountered in everyday phenomena like flowing fluids, holds a profound level of organization that scientists are still striving to understand.

  • Turbulence is a complex fluid motion characterized by chaotic fluctuations, unpredictable variations, and the formation of swirling patterns called vortices.
  • The balance between fluid inertia (fluid's tendency to keep moving) and viscosity (motion-slowing force) determines whether a flow is laminar (well-ordered) or turbulent (highly unstable).
    • When inertia dominates, turbulence emerges.
  • Applications of Turbulence:
    • Meteorological models leverage turbulence studies for more accurate short-term weather predictions, essential for disaster preparedness.
    • Studying turbulence helps assess the dispersion of pollutants in the atmosphere, influencing environmental policies.

Goldfish

  • Goldfish was one of the earliest fish to be domesticated and a relatively small member of the Carp family.
  • Releasing it into the wild can lead to giant sizes, making them invasive and harmful to native marine life, damaging fragile ecosystems.
    • It can eat almost anything and everything, including algae, aquatic plants, eggs, and invertebrates.
    • They can tolerate a wide range of water temperatures, reach sexual maturity quickly, and reproduce several times in one season.
    • Feral goldfish are also destructive, as they help spawn harmful algal blooms by consuming the algae and expelling nutrients that promote its growth.
