    • Through initiatives like the International Solar Alliance (ISA), India aims to promote renewable energy adoption in countries across Asia, Africa, and Latin America, contributing to sustainable development and climate resilience.

What is Global South?

  • About: Global South refers to a group of countries generally characterised as developing, less developed, or underdeveloped.
    • The term Global South is not geographical. Rather, its usage denotes a mix of political, geopolitical and economic commonalities between nations.
    • It encompasses countries with lower GDPs, higher poverty rates, and less developed infrastructure than the "Global North."
    • These nations are typically located in Africa, Latin America, the Caribbean, and Asia (excluding high-income countries like Japan, South Korea and Australia).

  • History:
    • The term Global South appears to have been first used in 1969 by political activist Carl Oglesby.
    • The Brandt Line, introduced by former German Chancellor Willy Brandt in the 1980s, visually represents the global north-south economic divide using per-capita GDP as a measure. 
    • The Group of 77 (G-77) was established in 1964 during the first UN Conference on Trade and Development (UNCTAD) session in Geneva, making it the largest intergovernmental organisation of developing nations at that time.

How can India Benefit from Prioritising Africa in its Global South Vision?

  • Economic Potential: Africa represents a vast economic opportunity for India. With Indian investments in Africa reaching USD 98 billion in 2023 and trade totaling USD 100 billion, the continent serves as a crucial market for Indian businesses.
  • Enhanced Strategic Ties: Africa's influence in global forums is rising, making it a strategic partner for India's global aspirations.
    • India's advocacy for African representation in forums like the G20 and UNSC reflects the shared vision for inclusive global governance.
    • In this regard, India has achieved several diplomatic victories, such as the African Union’s (AU) inclusion in the G20 in September 2023.
  • Tapping Youthful Demographics: Africa's young population, with 60% under the age of 25 years, presents immense potential for collaboration in education, technology, and innovation.

Accelerating Crop Diversification in India

For Prelims: Crop diversification, Wheat cultivation, Wheat blast disease, Bananas, Green Revolution in India, Leguminous crops, Biofuel, MSP.

For Mains: Needs For Crop Diversification in India, Concerns Related to Crop Diversification.

Source: DTE

Why in News?

In recent years, West Bengal has been witnessing a significant transformation in its agricultural landscape through crop diversification, particularly in districts bordering Bangladesh.

  • This shift is characterised by farmers moving away from traditional wheat cultivation towards alternatives like bananas, lentils, maize, and other crops.

What are the Reasons Behind the Shift from Wheat Production?

  • Wheat Blast Disease: The emergence of wheat blast disease in Bangladesh in 2016 led to a two-year ban on wheat cultivation in border areas of West Bengal, including Murshidabad and Nadia districts, prompting farmers to explore alternative crops.
    • Wheat blast disease is a fungal infection caused by the fungus Magnaporthe oryzae Triticum (MoT) that primarily affects wheat crops.
      • It manifests as dark lesions on wheat spikes, leaves, and stems, leading to severe yield losses.
  • Economic Viability: Farmers have highlighted the economic advantages of cultivating alternative crops such as bananas.
    • The profitability of crops like bananas during peak seasons, coupled with stagnant wheat prices and concerns over water consumption, has contributed to the shift.
  • Shift to Higher Output Crops: Maize cultivation has seen a significant uptick in the area as well, with production increasing eightfold from 2011 to 2023.
    • While maize prices may be lower per quintal compared to wheat, higher per-hectare output and demand from poultry and food processing industries make it a lucrative alternative.
    • Pulses and oilseeds production in this area has also surged.

Why India Needs to Focus on Crop Diversification?

  • About: Crop diversification refers to the practice of growing a variety of crops on a farm instead of focusing on a single crop.
    • The Green Revolution in India, through the introduction of high-yielding rice and wheat varieties, resulted in a substantial increase in food output, effectively reducing hunger and malnutrition.
      • However, the monoculture of these crops led to a decrease in crop variety, causing the decline of traditional, region-specific strains and a loss of genetic diversity.
      • For instance, India has lost over 100,000 traditional rice varieties since the 1970s due to the Green Revolution's impact.
    • Therefore, there is a need to shift towards crop diversification to promote sustainable agriculture.
  • Benefits of Crop Diversification:
    • Risk Reduction: In regions prone to drought, farmers can diversify their crops by growing both drought-tolerant varieties (like millets or sorghum) and water-intensive crops (like rice or vegetables).
      • If there's a water shortage, the drought-tolerant crops can still thrive, ensuring some level of harvest despite adverse conditions.
    • Soil Health Improvement: Planting leguminous crops like soybeans or peanuts can fix nitrogen in the soil, benefiting subsequent crops such as maize or wheat that require nitrogen-rich soil for optimal growth.
    • Market Opportunities: Diversifying crops can help farmers tap into niche markets or emerging trends.
      • For example, the rising demand for organic produce presents an opportunity for farmers to diversify into organic farming, which often commands higher prices in the market compared to conventionally grown crops.
    • Pest and Disease Management: Intercropping or mixed cropping, a form of crop diversification, can help manage pests and diseases.
      • For instance, planting marigold flowers alongside vegetable crops can deter pests, reducing the need for chemical pesticides and promoting natural pest control mechanisms.
    • Source of Biofuels: Crops like Jatropha and Pongamia are potential sources for biofuel production. This can offer farmers additional income opportunities and contribute to India's energy security.
  • Concerns:
    • Market Risks and Limited Opportunities: Farmers are often hesitant to switch from established crops like rice and wheat (which have assured government support through MSP) to lesser-known crops.
      • These alternatives may have fluctuating market prices or limited demand, leading to potential income loss.
    • Financial Constraints: Diversifying crops can require additional investment in seeds, equipment, and even acquiring new knowledge about cultivation practices.
      • Smallholder farmers, who make up a significant portion of India's agricultural sector, may not have the financial resources to readily adopt these changes.
      • Also, Millets like Jowar, Ragi, and Bajra are gaining traction due to their high nutritional value and ability to thrive in marginal lands.
        • However, creating a robust market for these requires investment in processing facilities to convert them into consumer-friendly products like ready-to-eat mixes or breakfast cereals.
    • Lack of Infrastructure and Storage: Perishable, diversified crops often require specialised storage and transportation facilities that may not be readily available in rural areas.
      • Without proper infrastructure, these crops can spoil quickly, leading to wasted produce and lost income.
    • Clash With Dietary Habits: Crop diversification in India, particularly in regions where rice and wheat are staples for a significant portion of the population, could potentially disrupt the established market dynamics and consumption patterns prevalent in these areas.

What are the Steps Taken by the Government Regarding Crop Diversification?

  • Crop Diversification Programme: The Department of Agriculture & Farmers Welfare (DA&FW) has been implementing the Crop Diversification Programme (CDP) since 2013-14, as part of the Rashtriya Krishi Vikas Yojana (RKVY), specifically targeting the Original Green Revolution States- Haryana, Punjab, and Western Uttar Pradesh.
    • This initiative aims to shift focus from water-intensive paddy cultivation to alternative crops such as pulses, oilseeds, coarse cereals, nutri cereals, and cotton.
  • Mission for Integrated Development of Horticulture (MIDH): It is a Centrally Sponsored Scheme for the holistic growth of the horticulture sector covering fruits, vegetables, root & tuber crops, mushrooms, spices, flowers, aromatic plants, coconut, cashew, cocoa and bamboo.
  • Increase in MSP for Kharif Crops: The Cabinet Committee on Economic Affairs (CCEA) has approved an increase in the Minimum Support Prices (MSP) for all mandated Kharif crops for the Marketing Season 2023-24.
  • Mera Pani-Meri Virasat Scheme (Haryana): It offers financial aid to farmers transitioning from paddy cultivation to water-saving alternatives like pulses, oilseeds, millets, and vegetables.

Way Forward

  • Agri-Tourism and 'U-Pick' Farms: Experiential tourism is gaining popularity. Creating 'U-Pick' farms where tourists can harvest their fruits and vegetables directly from the field can be a win-win for India.
    • This provides farmers with additional income, fosters a connection between consumers and agriculture, and promotes appreciation for diversified crops.
  • Biofortification through Gene Editing: Gene editing techniques like CRISPR can be used to develop crops with enhanced nutritional value.
    • This can address malnutrition concerns and create new markets for biofortified crops.
    • However, ethical considerations and stringent regulations need to be addressed.
  • Regenerative Agriculture for Sustainable Diversification: Regenerative agriculture practices like cover cropping, composting, and no-till farming can be integrated with diversified crop rotations to create a more sustainable and resilient agricultural system.

Source: TH

Why in News?

Recently, scientists have unearthed a 50,000-year-old sediment, a massive magneto fossil found deep in the Bay of Bengal, marking one of the youngest discoveries of its kind.

What are the Key Findings of the Study?

  • Monsoon Fluctuations: Analysis of sediment samples indicated fluctuations in monsoon strength during the last Glacial Maximum-Holocene period, impacting weathering and sedimentation.
  • Optimal Conditions for Magnetic Fossil Growth: The study suggests that warming events are not necessary for giant magneto fossil formation; instead, an optimal balance of iron, organic carbon, and suboxic conditions is crucial.
  • Information Encoded by Magnetofossils: Magnetofossils encode information about past environmental conditions, including nutrient availability, oxygen levels, and water stratification in ancient aquatic environments.

What are Magento Fossils?

  • About:
    • "Magneto Fossils" refer to fossilised remains of magnetotactic bacteria that contain magnetic minerals.
    • Magnetotactic bacteria leave fossilised magnetic particles in geological records.
  • Magnetotactic Bacteria:
    • Magnetotactic bacteria are mostly prokaryotic organisms that arrange themselves along the earth’s magnetic field. It was discovered by Salvatore Bellini in 1963.
    • These organisms follow the magnetic field to reach places that had optimal oxygen concentration. This process is facilitated by the presence of iron-rich crystals within their cells.
      • Magnetotactic bacteria create tiny crystals of magnetite or greigite within their cells to navigate changing oxygen levels and sediment saturation in water bodies.
      • Crystals within magnetotactic bacteria are arranged in a chain configuration through magnetotaxis.
    • Rare giant magneto fossils are less common than conventional magnetic fossils, these are likely produced by eukaryotes rather than bacteria.
  • Origin of Magnetofossils:
    • Most giant magnetofossils have been found in sediments dating to two geological time periods — Paleocen-Eocene Thermal Maximum (roughly 56,000 million years ago) and Middle Eocene Climatic Optimum (about 40 million years ago) — both of which were known for a rise in global temperature.
      • It suggested that the magnetofossils formed only during periods of extreme warming.
    • Discovery of giant magneto fossils from the Bay of Bengal were determined to be from the late Quaternary period, approximately 50,000 years ago, making them the youngest giant magneto fossils discovered to date.
      • The present study challenges the assumption that the magnetofossils formed only during periods of extreme warming.

Prokaryotes Eukaryotes
  • Prokaryotes are organisms that lack a true nucleus and membrane-bound organelles.
    • Their genetic material, typically a circular DNA molecule, is present in the cytoplasm without being enclosed within a nuclear membrane.
  • Prokaryotes include bacteria and archaea.
  • Key features include small, simple cells without a nucleus or organelles.
  • Eukaryotes are organisms that have cells containing a well-defined nucleus enclosed within a membrane.
    • Eukaryotic cells have a variety of membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and a complex network of internal membranes.
  • Eukaryotes include all types of animals, plants and fungi.
  • Key features include large, complex cells with a nucleus and various organelles.

Ozone Found on Jupiter's Moon Callisto

Source: TH

Why in News?

Recently, a team of scientists from various countries, including India, has uncovered compelling evidence suggesting the existence of ozone on Callisto, one of Jupiter's moons.

  • Previously thought of as a barren celestial body, scientists now consider that this icy moon could harbour conditions conducive to supporting life.

Note

Researchers recreated Callisto's surface conditions in the laboratory and exposed this setup to vacuum-ultraviolet photons and observed an absorption spectrum showing ozone formation, similar to what Hubble observed on Callisto in 1997.

  • Ozone presence suggests the presence of oxygen, essential for life.

What are the Key Features of Callisto?

  • About: Callisto ranks as one of Jupiter’s largest moons and is the third-largest moon in the Solar System, following Ganymede (Jupiter) and Titan (Saturn).
    • It was discovered in 1610, by Italian scientist Galileo Galilei along with Jupiter’s three other largest moons: Ganymede, Europa and Io.
    • As per NASA, after Saturn (146), Jupiter (95) boasts the highest number of moons in the Solar System.
  • Features: It is primarily composed of water ice, rocky materials, sulfur dioxide, and organic compounds.
    • Its surface is heavily cratered, indicating a long history of being struck by asteroids and comets.
    • It also lacks the extensive seismic activity seen on some of Jupiter’s other moons, such as Io and Europa.

What are Some Other Potentially Habitable Celestial Bodies?

  • Habitable Zone: Habitable zone is the distance from a star at which liquid water could exist on orbiting planets’ surfaces.
    • Habitable zones are also known as Goldilocks’ zones, where conditions might be just right (neither too hot nor too cold) for life.

  • Potential Habitable Celestial Bodies
    • Kepler 22b: It is the first planet confirmed by NASA's Kepler mission to orbit within the habitable zone of a sun-like star.
      • The planet, 2.4 times the size of Earth, resides in a region where liquid water could potentially exist, vital for sustaining life.
    • Proxima Centauri b: Proxima Centauri b is an exoplanet, which is a planet that orbits a star other than our sun.
      • It is located in the habitable zone of its star, which means that it is the right distance from the star to potentially have liquid water on its surface.
      • Proxima Centauri b is also very close to Earth, at only 4.2 light-years away.
    • TRAPPIST-1 System (Star System): The TRAPPIST-1 system is a group of seven Earth-sized planets orbiting an ultra-cool dwarf star about 39 light-years away.
      • Several of the planets within the TRAPPIST-1 system are located within the habitable zone, and some may have liquid water on their surfaces.

Significance of Ozone

  • Ozone, composed of three oxygen atoms (O3) bonded together, plays a vital role in shielding planets from harmful ultraviolet radiation.
    • The ozone layer is found in the lower part of the earth’s stratosphere, around 15-35 km above ground.
  • It acts as a protective layer in Earth's atmosphere, absorbing most of the sun's harmful ultraviolet (UV) radiation and preventing it from reaching the surface.
    • Ultraviolet radiation in particular is harmful to many species (but also useful to some others).
    • Two of its components, called ultraviolet-B and ultraviolet-C can damage DNA, trigger mutations, and increase the risk of skin cancer and cataracts in humans.
