Overview
The 21 October 2026 Daily Current Affairs edition focuses on three distinct developments with lasting examination value: outcomes recorded at the Shanghai Cooperation Organisation (SCO) Council of Heads of Government meeting, a Technology Development Board agreement to advance indigenous quantum-secure and sensing technologies, and the addition of two wetlands to India's Ramsar-site tally. Each item is tied to a completed decision, agreement or designation reported before the edition cutoff.

International Relations - 25th SCO Council of Heads of Government Meeting
The 25th meeting of the SCO Council of Heads of Government (CHG) was held in Dushanbe, Tajikistan, on 20 October 2026. Raksha Mantri Rajnath Singh represented India and called for concerted action to dismantle the entire ecosystem of terrorism. His remarks also stressed that connectivity should respect sovereignty and territorial integrity.
The current milestone was more than a scheduled appearance. The Heads of Delegation adopted the Joint Communique of the 25th CHG meeting, the SCO budget for 2027, and the Action Plan for the Multilateral Trade and Economic Cooperation Programme (PMTEC) for 2026-2030. The release also recorded the meeting's review of multilateral economic and trade cooperation in transport, finance, the digital economy and social development.
The SCO CHG is an important mechanism for practical economic cooperation and the organisation's annual budget. It is different from the SCO Council of Heads of State, which is the top-level political summit. India has been a full SCO member since 2017. The release also noted the SCO Summit decisions to establish the Universal Centre in Tashkent and the Anti-Drug Centre in Dushanbe as permanent bodies; these were decisions recalled at the CHG meeting, not a new Indian treaty or a new national law.

Science and Technology - TDB-DST Support for Quantum-Secure Networks
On 16 October 2026, the Technology Development Board (TDB), under the Department of Science and Technology (DST), signed an agreement with QNu Labs Private Limited for Rs 150 crore of support under the Research Development and Innovation (RDI) Fund. The supported project has a total cost of Rs 300 crore and aims to develop an indigenous technology backbone for India's Quantum Secure and Sensing Networks (IQSN).
The agreement is a technology-development and financing milestone, not evidence that a nationwide quantum-secure network has already been deployed. The programme is intended to advance a portfolio of technologies from Technology Readiness Levels (TRL) 4-5 towards TRL-9, through further research, engineering refinement, integration and validation. The financial support is to be provided through Optionally Convertible Debt (OCD).
The proposed technology stack is organised around four connected pillars: identity security, location integrity, network security and time integrity. The release links these to device authentication, detection of navigation spoofing, quantum-secure communications, high-precision timing and secure time synchronisation. Its network-security work includes chip-based and satellite-based Quantum Key Distribution (QKD), while the broader programme also includes quantum sensing and quantum-safe hardware and software.
This agreement is distinct from the free-space QKD field demonstration covered in the 4 October edition. The earlier story concerned a completed 5.56-km demonstration; this later development concerns public RDI financing and a proposed path from mid-level technology readiness towards deployable systems.

Environment - India Adds Two Ramsar Sites
The Ministry of Environment, Forest and Climate Change announced on 15 October 2026 that India's Ramsar-site tally had reached 103 after the designation of Sukhna Wetland in Chandigarh and Sauj Jheel in Uttar Pradesh as the latest additions. The material development is the reported designation and the resulting change in India's national tally, not merely a ministerial visit or a tourism announcement.
Under the Convention on Wetlands, Ramsar Sites are wetlands included in the List of Wetlands of International Importance. Their inclusion gives the site national and international recognition and reflects a government commitment to maintain its ecological character. The designation does not mean that the site becomes a national park or that all human activity is automatically prohibited.
The current additions are useful for revision because they connect a current Indian conservation milestone with the institutional purpose of the Ramsar List. Sukhna is in the Union Territory of Chandigarh, while Sauj Jheel is in Uttar Pradesh. The official PIB release highlights wetland conservation, water and climate security, biodiversity and local livelihoods; those are the policy dimensions of the development.

Quick Revision Table
| Topic | Current milestone | Exact status | Key exam fact |
|---|---|---|---|
| SCO CHG meeting | 25th Council of Heads of Government meeting held in Dushanbe | Joint Communique, 2027 budget and PMTEC Action Plan 2026-2030 adopted | CHG handles practical economic cooperation and the SCO annual budget |
| QNu Labs RDI support | TDB-DST signed a Rs 150 crore support agreement | Development and financing programme; not a completed network deployment | Four pillars: identity security, location integrity, network security and time integrity |
| Ramsar additions | Sukhna Wetland and Sauj Jheel designated as latest additions | India's Ramsar tally reached 103 | Sukhna is in Chandigarh and Sauj Jheel is in Uttar Pradesh |
Exam Focus
For the SCO, distinguish the CHG from the Heads of State Council and remember the documents adopted at the meeting. For the QNu Labs agreement, revise the RDI Fund, the TRL 4-5 to TRL-9 progression, OCD financing and the four technology pillars; do not describe the proposed programme as an already deployed network. For the Ramsar development, connect the current tally with the List of Wetlands of International Importance and the commitment to maintain ecological character.

Previous Coverage and Rejected Candidates
The final 1-20 October editions were checked at event level. The SCO appearance was rejected in the 19 October source file because it was still a scheduled future meeting; the completed 20 October meeting and adopted documents are a new material milestone. The QNu Labs item is distinct from the 4 October free-space QKD demonstration: the institution and technology family overlap, but the action, financing instrument and material date are different. The two Ramsar additions were not covered in the final editions.
| Candidate | Primary source | Rejection reason |
|---|---|---|
| 21 October Police Commemoration Day tributes | PIB PMO release listing | Routine anniversary observance without a new policy, legal or operational milestone |
| Sanskrit Subhashitam shared by the Prime Minister | PIB PMO release listing | Cultural communication, not an exam-relevant current policy development |
| Agri Welfare Portal launch | PIB PRID 2325129 | Already rejected in the 20 October editorial review as a service-portal launch with limited standalone exam value for that edition |
