बढ़ते तापमान और तीव्र शहरीकरण की पृष्ठभूमि में, डिस्ट्रिक्ट कूलिंग भारत के सतत विकास लक्ष्यों के अनुरूप एक जलवायु-उत्तरदायी एवं शहरी नियोजन समाधान के रूप में उभर रहा है।
डिस्ट्रिक्ट कूलिंग क्या है?
डिस्ट्रिक्ट कूलिंग एक केंद्रीकृत प्रणाली है जो इन्सुलेटेड भूमिगत पाइपों के नेटवर्क के माध्यम से अनेक भवनों को वातानुकूलन उपलब्ध कराती है।
एक केंद्रीय संयंत्र शीत जल (लगभग 6–7°C) उत्पन्न करता है, जो जुड़े हुए भवनों तक पहुँचाया जाता है।
हाल ही में राष्ट्रीय हरित अधिकरण (NGT) की एक पीठ ने ग्रेट निकोबार द्वीप मेगा-अवसंरचना परियोजना के मार्ग को प्रशस्त किया, यह उल्लेख करते हुए कि ‘इसके रणनीतिक महत्व’ और ‘अन्य प्रासंगिक विचारों’ को ध्यान में रखा गया है।
ग्रेट निकोबार परियोजना के बारे में
यह एक बड़े पैमाने की अवसंरचना पहल है जिसे नीति आयोग द्वारा परिकल्पित किया गया है और औपचारिक रूप से ग्रेट निकोबार द्वीप विकास परियोजना कहा जाता है।
इसका क्रियान्वयन अंडमान और निकोबार द्वीप समूह एकीकृत विकास निगम (ANIIDC) द्वारा किया जा रहा है।
A recent study shows that the Chincha Indians used nitrogen-rich seabird guano to significantly boost maize production in coastal Peru and strengthened the pre-Inca Chincha Kingdom.
Chincha Indians
The Chincha were a pre-Inca civilisation located in the Chincha Valley on the southern coast of present-day Peru.
They flourished between 1000–1400 CE.
At their peak, their population is estimated to have reached nearly 100,000.
The import of refurbished high-end medical equipment has major implications for healthcare access, industry policy, and patient safety.
What Are Refurbished Medical Devices?
Refurbished medical devices are previously used systems that have been restored to their original operating specifications and resold at significantly lower prices.
These are typically capital-intensive machines used in advanced diagnostics and surgery.
India, ranked third in the world in artificial intelligence by Stanford University’s 2025 Global AI Vibrancy rankings and is increasingly using Artificial Intelligence to strengthen sustainability, and resilience in its agriculture sector.
How is AI in Agriculture Critical for India?
Indian agriculture faces structural constraints such as fragmented landholdings, climate variability, price volatility, and low productivity.
Climate change has increased the frequency of extreme weather events, making predictive technologies essential.
Small and marginal farmers (over 85% of total farmers) require affordable, data-driven advisory systems.
India’s generalist post-Independence service rules, once vital for nation-building, now hinder effective scientific governance in an era driven by technology and complex environmental challenges.
The Core Issue
Scientists entering government are governed by general civil service rules.
Administrative systems prioritise hierarchy, uniformity, and procedural compliance.
Scientific work requires evidence-based reasoning, transparency, peer review, and open discussion of uncertainty.
As per NITI Aayog India’s electricity mix could shift decisively from coal-heavy to renewable-led by 2070.
Major Highlights of the Study
Coal remains the backbone of India’s electricity landscape, accounting for nearly 74% of generation and providing dependable, low-cost base-load power.
Under the Current Policy Scenario (CPS) renewable energy’s share in electricity generation could rise from around 20% in 2024-25 to more than 80% by 2070.
In the same scenario, coal’s share in electricity generation could decline sharply to 6-10 per cent by 2070.
India is promoting bio-based chemicals and enzymes as key pillars of a green bioeconomy, linking climate action, industrial growth, and rural income diversification.
What Are Bio-Based Chemicals and Enzymes?
Bio-Based Chemicals: Bio-based chemicals are industrial chemicals produced from biological feedstocks such as sugarcane, corn, starch, agricultural residues, or other forms of biomass.
They are manufactured through fermentation, microbial processes, or enzymatic pathways, replacing fossil fuel-based raw materials.
Examples include organic acids (such as lactic acid), bio-alcohols, solvents, surfactants, and intermediates used in plastics, cosmetics, and pharmaceuticals.
