Highlights
- Demography: India's national fertility rate stands at 2.0, below the replacement level of 2.1. Southern states are at 1.4 to 1.5.
- Energy: India's wind energy potential at 150 metres height is 1,163.86 GW. Installed capacity is 44.89 GW. Tamil Nadu leads with 10,603 MW.
- Food: FAO's 2024 report puts India's hidden agrifood system costs at 1.3 trillion dollars annually, with 73 per cent from unhealthy dietary patterns.
- Defence: France is evaluating the Pinaka rocket system. The Animal Health Security Initiative was launched with 25 million dollars from the Pandemic Fund.
1. Declining fertility and its consequences
GS area: Society, Geography, Economy
India's demographic profile is shifting. The total fertility rate (TFR) has fallen below the replacement level.
- TFR: The average number of children a woman is expected to bear over her lifetime. India's TFR is now about 2.0.
- Replacement level: 2.1. Below this, a population will eventually shrink absent migration.
- Southern state data: Tamil Nadu and Kerala are at about 1.4 to 1.5.
- Senior citizens projection: 10.1 per cent of India's population was over 60 in 2021. This rises to 15 per cent by 2036.
- Kerala: 22.8 per cent of Kerala's population will be over 60 by 2036. That is a dependency burden that matches ageing European societies.
- Parliament reallocation risk: When the constitutional freeze on Lok Sabha seats ends post-2026, states with lower fertility (southern states) stand to lose seats while states with higher fertility (UP, Bihar) gain. Tamil Nadu is projected to lose 9 seats; UP to gain 12.
This is politically explosive. The freeze was extended in 1977 and 2001 precisely to avoid penalising states that implemented family planning more effectively.

2. Wind energy: India's untapped potential
GS area: Economy (energy), Environment
India's wind energy sector has large untapped potential, and states are now addressing ageing infrastructure through repowering.
- Potential at 150 metres height: 1,163.86 GW nationally. This is the height of modern tall wind turbines.
- Potential at 120 metres height: 695.51 GW nationally.
- Installed capacity: 44.89 GW in 2024. Less than 4 per cent of the technical potential at 150 metres is deployed.
- Tamil Nadu: 10,603.5 MW installed capacity, the second-highest state after Rajasthan. Wind potential of 68.75 GW at 120 metres.
- Tamil Nadu Repowering Policy 2024: Replaces ageing 250 kW turbines with modern 2.5 MW units. A single repowered turbine produces 10 times the output of the unit it replaces.
- Repowering: Removing old wind turbines and installing newer, larger, more efficient ones. Global practice in Germany and Spain. India has a large stock of first-generation turbines now past their 20-year life.

3. FAO's hidden agrifood costs: India's food system
GS area: Economy, Agriculture
The FAO State of Food and Agriculture 2024 report quantified hidden costs in national food systems.
- India's hidden costs: 1.3 trillion dollars annually, the third highest globally.
- Breakdown: 73 per cent comes from unhealthy dietary patterns (diet-related disease, productivity loss).
- Global context: Total global hidden agrifood costs are 12 trillion dollars per year. Dietary risk alone is 8.1 trillion dollars.
- FAO: Food and Agriculture Organization of the United Nations. Headquartered in Rome. India is a founding member.
- Policy implication: When food systems are measured only by production volumes and prices, hidden costs (nutrition, health, environment) are invisible. The FAO framework pushes for "true cost accounting."

4. State of Food and Agriculture: Implications for UPSC
GS area: Economy, Agriculture
The FAO report is a direct prelims trigger because the numbers are specific and testable.
- India ranked third globally in hidden agrifood costs, behind the US and China.
- 73 per cent of India's hidden costs come from dietary patterns, not environmental damage or labour exploitation, which is the reverse of what intuition might suggest.
- POSHAN Abhiyaan: India's National Nutrition Mission. A government response to diet-related malnutrition.
- Eat Right India: FSSAI's initiative to promote safe and nutritious food choices.
- Food fortification: Mandatory fortification of staple foods (rice, wheat flour, oil) is one policy tool the government uses to address micronutrient deficiency at scale.
Static linkage: Nutrition policy, government schemes, food systems.
5. Animal Health Security Initiative
GS area: Health, International Organisations
A new international initiative for animal disease surveillance was launched.
- Launch date: 25 October 2024.
- Funding: 25 million dollars from the Pandemic Fund, a G20-endorsed mechanism for pandemic preparedness.
- Completion timeline: August 2026.
- Implementing partners: Asian Development Bank, World Bank and FAO.
- Purpose: Strengthen animal disease surveillance systems in vulnerable countries. Animal diseases are the origin of most pandemic-level human infections (zoonotic origin). COVID-19, SARS, Ebola and H5N1 all have animal reservoirs.
Static linkage: One Health, pandemic preparedness, international organisations.
6. Briefly noted
- Comics Commandos in Assam: Thirty young people in Goalpara district were trained to create comics to campaign against child labour and child marriage. A grassroots advocacy initiative using visual storytelling.
- QS Asia Rankings 2025: IIT Delhi ranked 44th in Asia, the highest-ranked Indian institution. Seven Indian universities in the top 100. India's count grew from 11 ranked institutions in 2015 to 46 in 2025, a 318 per cent increase.
