Environmental and Science Awards

Beyond the Nobel Prize, several dedicated science and environment prizes recur in Indian exam papers, mostly because Indian scientists and institutions frequently feature among their winners.

• Shanti Swarup Bhatnagar Prize: India's most prestigious science award for Indian scientists working in India, instituted in 1958 and administered by the Council of Scientific and Industrial Research (CSIR), given annually to scientists under 45 (the age cutoff is itself a frequently tested detail) across categories including physics, chemistry, biology, mathematics, medicine, engineering, and earth/atmospheric/ocean/planetary sciences. Named after Shanti Swarup Bhatnagar, the founder-director of CSIR, it functions as a kind of "domestic Nobel" for younger Indian researchers.
• Stockholm Water Prize: an international award often called the "Nobel Prize for water," recognising outstanding achievements in water-related activities and water resources management, presented annually at World Water Week in Stockholm — Indian institutions and individuals (including, in past years, Indian NGOs working on watershed management and river rejuvenation) have featured among its winners, making it a recurring "international award, India connection" one-liner.
• Champions of the Earth Award: the United Nations' highest environmental honour, awarded by the UN Environment Programme (UNEP); India's Narendra Modi received it in 2018 (jointly with France's Emmanuel Macron, for the International Solar Alliance) — a fact frequently paired with India's broader renewable-energy and climate-diplomacy current-affairs coverage.
• Blue Planet Prize: an international environmental award recognising outstanding achievements in scientific research contributing to the solution of global environmental problems, presented by Japan's Asahi Glass Foundation — a less frequently tested but occasionally appearing name in this cluster.
• Indira Gandhi Prize for Peace, Disarmament and Development: an Indian (not international) award, instituted in 1986 by the Indira Gandhi Memorial Trust, given to individuals or organisations for distinguished contribution to promotion of international peace, development, and a new international economic order — worth knowing precisely because its name ("Indira Gandhi Prize... Peace, Disarmament and Development") is easy to conflate with the Nobel Peace Prize despite being an entirely separate, India-based award.
• Kalinga Prize for the Popularisation of Science: an international award presented via UNESCO, instituted in 1951 by the Kalinga Foundation Trust (Odisha), recognising individuals who have made an outstanding contribution to the public understanding and popularisation of science — India's Jagjit Singh and several other Indian science communicators have received it across the decades, making it one of the older India-linked international science prizes, predating even the Shanti Swarup Bhatnagar Prize by several years.
• Infosys Prize: a private (non-government) Indian science and research prize, instituted in 2009 by the Infosys Science Foundation, awarded annually across six categories — Engineering and Computer Science, Humanities and Social Sciences, Life Sciences, Mathematical Sciences, Physical Sciences, and Social Sciences — carrying one of the largest cash awards among India's own science honours, and increasingly cited alongside the Shanti Swarup Bhatnagar Prize as a marker of an Indian scientist's rising international profile.
• G.D. Birla Award for Scientific Research: an Indian award instituted in 1991 by the K.K. Birla Foundation, given annually to an Indian scientist (of any age, unlike the Bhatnagar Prize's under-45 cutoff) for outstanding contribution to any branch of science.
• Homi Bhabha Award / Homi Bhabha Fellowship: administered by the Homi Bhabha Fellowship Council, distinct from the Bhabha Atomic Research Centre discussed elsewhere in general-science revision material, supporting advanced research across science, humanities, and the arts.

Memory hook — "Bhatnagar builds young India's scientists, before 45": the Shanti Swarup Bhatnagar Prize's under-45 eligibility rule is the single most-tested numeric detail attached to it — treat "45" as inseparable from the award's name.

Practice Recall: Name the age cutoff for Shanti Swarup Bhatnagar Prize eligibility, the body that administers it, and the international award sometimes called "the Nobel Prize for water."

Answer: Under 45 years; administered by CSIR (Council of Scientific and Industrial Research); the Stockholm Water Prize.
