    \u00a0<\/strong>What is a Digital Arrest?<\/strong><\/p>\n

      \n
    • A digital arrest is a\u00a0cyber scam\u00a0where fraudsters impersonate police, CBI, RBI, or government officials, convincing victims they are implicated in serious crimes.\u200b<\/li>\n
    • Victims are\u00a0threatened with fake arrest, legal action, or public shaming\u00a0unless they pay money or share sensitive data.\u200b<\/li>\n
    • There is\u00a0no legal basis\u00a0for a “digital arrest” in India.\u200b<\/li>\n<\/ul>\n

        2. Focus from food security to nutrition security: PM<\/u><\/strong><\/h2>\n

        General Studies Paper III (GS-III): Economy and Development.\u200b<\/p>\n

        Context: <\/strong>Prime Minister Narendra Modi, at the inaugural Emerging Science Technology and Innovation Conclave (ESTIC) on Nov 3, 2025, emphasized shifting India\u2019s focus from\u00a0food security to nutrition security.\u200b<\/p>\n

          \n
        • He highlighted the need to develop\u00a0biofortified crops, genomic biodiversity mapping, clean energy innovations\u00a0and called for\u00a0doubling research and development (R&D) efforts.\u200b<\/li>\n<\/ul>\n

          \u00a0<\/strong>Background: From Food Security to Nutrition Security<\/strong><\/p>\n

          Food Security:<\/strong><\/p>\n

            \n
          • Defined as availability, access, and affordability of sufficient food to meet caloric needs.<\/li>\n
          • India achieved improved food security notably since the 1970s Green Revolution.<\/li>\n<\/ul>\n

            Problems with Food Security Alone:<\/strong><\/p>\n

              \n
            • Despite food availability,\u00a0malnutrition and micronutrient deficiencies persist\u00a0in large segments of population.<\/li>\n
            • Food security doesn\u2019t guarantee\u00a0nutrition adequacy, health, and physical\/ cognitive development.<\/li>\n<\/ul>\n

              Nutrition Security:<\/strong><\/p>\n

                \n
              • Focuses on\u00a0quality of diet\u00a0and ensuring access to essential nutrients, vitamins, proteins, and minerals.<\/li>\n
              • Aims to address\u00a0malnutrition, stunting, wasting, and micronutrient deficiencies\u00a0for better health outcomes.<\/li>\n<\/ul>\n

                \u00a0<\/strong>Key Highlights from PM\u2019s Address<\/strong><\/p>\n

                  \n
                • Shift focus from just\u00a0caloric food security to nutrition security.<\/li>\n
                • Develop\u00a0biofortified crops\u00a0to combat malnutrition and micronutrient deficiencies.<\/li>\n
                • Map\u00a0India\u2019s genomic biodiversity\u00a0to help personalized medicine and agriculture.<\/li>\n
                • Innovate in\u00a0low-cost fertilisers\u00a0and\u00a0new clean battery storage technologies.<\/li>\n
                • Boost\u00a0research and development (R&D)\u00a0funding and make\u00a0science-backed innovations\u00a0mainstream.<\/li>\n
                • Double government expenditure on R&D over the past decade, increase patents and deep-tech startups.<\/li>\n<\/ul>\n

                    \n
                  • India faces a\u00a0dual burden of malnutrition and food insecurity\u00a0\u2014 while calories may be available,\u00a0nutritional quality is insufficient.<\/li>\n
                  • Traditional focus on calories has missed\u00a0hidden hunger from micronutrient deficiencies\u00a0(iron, vitamin A, zinc, protein).<\/li>\n
                  • Malnutrition leads to\u00a0stunted growth, weakened immunity, poor cognitive function\u00a0\u2014 major public health challenge.<\/li>\n
                  • Science-driven innovations like\u00a0biofortification, genomics, affordable fertilizers\u00a0can address these deeper nutrition issues.<\/li>\n
                  • Ensures\u00a0long-term health, productivity, and sustainable development\u00a0for the population.<\/li>\n<\/ul>\n

                    • High rates of\u00a0child stunting (approx. 30%) and wasting, anemia, low birth weight.<\/li>\n
                    • Large rural-urban and socio-economic disparities persist despite overall economic growth.<\/li>\n
                    • Government schemes like Poshan Abhiyaan target it, but quality and impact vary.<\/li>\n
