  • Modern Indian History-Events and Personalities

    On this day over 500 years ago, the Portuguese conquered Goa

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Portuguese rule and liberation of Goa

    Why in the News?

    • On November 25, the Portuguese conquered Goa, establishing first territorial possession in India by any colonists.
      • This marked the beginning of Portugal’s 400-year colonial rule in the region, which ended only in 1961, making them the last colonial power to leave India.

    On this day over 500 years ago, the Portuguese conquered Goa

    Why the Portuguese came to Goa?

    • Vasco da Gama’s voyage in 1498 revealed the thriving trade networks in the Indian Ocean.
    • The Portuguese aimed to capitalize on the wealth from the Indian Ocean trade routes.
    • Rivalry with Muslim-controlled trade routes prompted the Portuguese to establish a military presence in the region.
      • In 1505, the Portuguese State of India was formally established, six years after Vasco da Gama’s arrival.
    • Francisco de Almeida, the first Viceroy, set up the first base in Fort Manuel (now part of Kochi).
      • The Portuguese controlled the Island of Bom Bahia (later Bombay) until it was ceded to England in 1661.

    How Alfonso de Albuquerque conquered Goa?

    • Albuquerque (Viceroy, 1509-1515) understood that Goa was essential for controlling the maritime trade routes in the East.
    • The decision to attack Goa was influenced by Timmayya, a debated figure, either a Malabari pirate or an aristocrat with links to the Vijayanagara Empire.
    • Albuquerque’s first attack on Goa (February-March 1510) was largely successful due to the unpopularity of Sultan Yusuf Adil Shah’s rule among Goa’s Hindu population.
      • Many locals supported the Portuguese against the Sultan’s rule.
    • After being stranded on the Mandovi River during the monsoon season, Albuquerque received reinforcements from Portugal.
    • In November 1510, with reinforcements, Albuquerque launched a successful attack and retook Goa.

    Who Was Timmayya?

    • Timmayya, a key figure in the conquest of Goa, is described in various sources as a pirate from Malabar.
      • However, other historians argue that he was of noble birth and held a prestigious position in the Vijayanagara Empire.
      • According to historians, Timmayya was actually a high-ranking admiral in the Vijayanagara navy.
    • Though the Portuguese regarded him as a corsair or pirate, he was in fact executing orders from the Vijayanagara Empire, attacking Portuguese and rival merchant ships on his empire’s behalf.
    • While some historians argue that Timmayya’s counsel was pivotal in the timing of the attack on Goa, others suggest that Albuquerque may have already planned the assault, with Timmayya’s advice simply solidifying the decision.

    Why did Timmayya want Goa conquered?

    • The rulers of the Vijayanagara Empire had long eyed Goa after it was lost to the Sultan of Bijapur.
    • Timmayya’s personal motivations were likely shaped by the empire’s strategic interest in regaining control of the region, as Goa was seen as a valuable territory in both military and economic terms.

    • The plant is located in Laltipara, Gwalior, within the largest cowshed in the region, Adarsh Gaushala, which houses over 10,000 cattle.
      • It spans over 5 acres.
      • It is India’s first self-sufficient gaushala with a modern CBG plant, where cow dung and organic waste (such as vegetable and fruit waste from mandis and households) are processed into valuable biogas.
    • The project, developed at a cost of ₹31 crores, is a collaboration between Gwalior Municipal Corporation and the Indian Oil Corporation.

    Working features:

    • Bio CNG: The plant produces 2 tons of compressed Bio CNG daily from 100 tons of cattle dung, providing a cleaner, eco-friendly alternative to traditional fossil fuels.
    • Organic Manure: The plant also generates 10-15 tons of dry bio-manure daily, which is a valuable by-product for organic farming.
    • Windrow composting: The plant incorporates windrow composting, located adjacent to the main facility, which enhances organic waste processing.

     

    What is Compressed Biogas (CBG)?

    Details
    About
    • CBG is a renewable natural gas produced from the biochemical conversion of organic waste into methane.
    • It is chemically similar to CNG (compressed natural gas) and can be used as an alternative to fossil fuels in transportation, cooking, and power generation.
    Process of Making CBG
    1. Collection of Organic Waste: Organic waste such as agricultural residue, animal dung, food waste, and municipal solid waste is collected from farms, industries, and households.
    2. Anaerobic Digestion: Waste is placed in an airtight chamber, where microorganisms break it down without oxygen, producing biogas (methane, carbon dioxide, trace gases).
    3. Purification: The raw biogas undergoes purification through methods like pressure swing adsorption, water scrubbing, or membrane separation to remove impurities like CO₂, H₂S, and water, leaving pure methane.
    4. Compression: The purified methane is compressed to 200-250 bar pressure to form CBG, reducing volume for storage and transportation.
    5. Storage and Distribution: It is stored in high-pressure cylinders or tanks and transported to fuel stations or industries for various applications.
    Significance of CBG
    • Reduces fossil fuel dependence.
    • Mitigates landfill methane emissions.
    • CBG can replace CNG, reducing pollution.
    • Utilizes local organic waste.
    • Creates jobs, promotes organic farming, and provides eco-friendly fertilizers.

    Why in the News?

    The recent G20 Leaders’ Summit in Rio de Janeiro, Brazil, featured the official launch of the Global Alliance Against Hunger and Poverty (referred to as “the Alliance”).

    What are the primary objectives of the Global Alliance?

    • Eradication of Hunger and Poverty: The Alliance aims to eliminate hunger and poverty by 2030, aligning with the United Nations’ Sustainable Development Goals (SDGs).
    • Support for Vulnerable Populations: It focuses on providing targeted assistance to vulnerable groups through various initiatives, including cash transfers and school meal programs.
    • Resource Mobilization: The initiative emphasizes large-scale resource mobilisation to support its objectives, aiming to reach 500 million people through income distribution programs by 2030.

    Who are the key stakeholders involved in this initiative?

    • The Alliance has 148 founding members, including 82 countries such as India, Brazil, and Bangladesh.
    • It includes participation from 26 international organizations, such as the Food and Agriculture Organization (FAO) and UNICEF.
    • Nine financial institutions and 31 philanthropic foundations and non-governmental organizations are also involved in supporting the Alliance’s goals.

    How will Alliance function?

    • The Alliance serves as a platform for countries to share best practices and access technical expertise or financial support from other member nations.
    • It offers more than 50 evidence-based policy instruments that member countries can utilize to develop their national strategies against hunger and poverty.
    • Unlike traditional funding bodies, the Alliance does not have an exclusive fund but acts as a matchmaking entity connecting countries in need with donors and technical support providers. Its operational costs are estimated at $2-3 million annually, funded by member contributions.

    What challenges does the Global Alliance aim to address in combating hunger and poverty?

    • Impact of COVID-19: The pandemic has exacerbated issues of hunger and poverty, reversing progress made toward the SDGs. The Alliance aims to counteract these setbacks by fostering international cooperation.
    • Global Inequalities: It addresses deepening social, racial, and gender inequalities that have been intensified by recent global crises.
    • Food Insecurity Projections: Current trends suggest that without intervention, millions will continue to live in extreme poverty and hunger by 2030—double the target levels set in the SDGs. The Alliance seeks to reverse these projections through coordinated action.

    Conclusion: The Global Alliance Against Hunger and Poverty aligns with SDGs 1 (No Poverty) and SDG 2 (Zero Hunger) by mobilizing resources, fostering collaboration, and implementing targeted interventions to combat hunger, poverty, and inequalities, ensuring a sustainable and inclusive future.
