Q. The Office of the Principal Scientific Adviser plays a critical role in bridging science and policy in India. Examine its institutional mandate and recent contributions to India's science governance architecture. (15 marks, 250-350 words)

The Office of the Principal Scientific Adviser (PSA), headed by Prof. Ajay Kumar Sood, is the Union government's apex science-advisory body, tasked with converting scientific evidence into actionable policy [2]. Its influence rests on convening authority rather than executive power — a strength and a structural limit.

Institutional mandate - Advisory: supplies evidence-based inputs to the Cabinet and ministries on strategic science, technology and innovation choices. - Foresight and road-mapping: anchors the Mega Science Vision-2035 (MSV-2035) exercise, constituting working groups to assess the global and Indian state-of-the-art, conduct a SWOT analysis, identify new mega-science projects, and recommend funding and management structures [1]. - Inter-ministerial coordination: convened a stakeholders' meeting on air quality and climate change bringing together MoES, MoEFCC, CAQM, IMD, CPCB, ICMR and NITI Aayog to build an integrated, science-based framework [2]. - Ecosystem-building and science diplomacy: links academia, industry and foreign partners.

Recent contributions - MSV-2035 Climate Research chapter (nodal institution IISc Bengaluru), submitted to the PSA and made public in June 2026, candidly recorded that India has "almost lost" the ability to build its own scientific instruments, that uncalibrated imports corrupt published data, and that the climate effects of large solar and wind installations remain poorly understood [5]. - PSA–FICCI MoU (May 2026) to bridge industry, academia and research institutions and support translation and commercialisation, complementing the government's RDI fund [3]. - IN-UK-STP Dashboard (November 2025), mapping 143 India–UK projects against Science and Innovation Council goals and the SDGs [4].

Limitations - Purely advisory: no financial or executive authority; implementation rests with line ministries such as MoES and DST. - Recommendations like instrument indigenisation await PLI-type instruments and calibration infrastructure.

The PSA's office has evolved from an advisory desk into an institutional bridge — diagnosing gaps that departmental reporting often conceals. Its candour on instrument dependence shows the model works; converting such diagnoses into budgeted missions, with statutory follow-up mechanisms, would align it fully with India's self-reliance and SDG-9 innovation goals.
