International Days in September and October

International observances during September and October focus heavily on environmental conservation, maritime laws, nuclear disarmament, food security, outer space exploration, and human development indices. These dates are critical source material for the UPSC Civil Services Examination (Prelims) under the categories of “Current Events of National and International Importance,” “Economic and Social Development,” and “General Issues on Environmental Ecology, Bio-diversity and Climate Change.”

Technical Trivia and Conceptual Linkages for UPSC Prelims

Atmospheric Science & Treaty Extensions (World Ozone Day Linkage)

• Ozone Chemistry: Stratospheric ozone (O₃) absorbs harmful ultraviolet (UV-B) radiation from the sun. The destruction of ozone occurs when chlorine and bromine atoms interact with ozone molecules in the stratosphere, catalyzed by solar radiation.
• The Kigali Amendment: Unlike CFCs, Hydrofluorocarbons (HFCs) do not deplete the stratospheric ozone layer; however, they possess high Global Warming Potential (GWP). The Kigali Amendment to the Montreal Protocol legally binds member states to reduce HFC consumption by over 80% by the late 2040s, aiming to prevent up to 0.5°C of global warming by 2100.

The Outer Space Treaty of 1967 (World Space Week Linkage)

• Core Principles: The Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies forms the foundation of international space law.
• Key Prohibitions: It explicitly prohibits nation-states from placing weapons of mass destruction (WMD) in Earth’s orbit, installing them on celestial bodies, or stationing them in outer space. It also mandates that outer space is free for exploration by all states and cannot be claimed under national sovereignty.

The Sendai Framework Seven Global Targets (Disaster Risk Reduction Linkage)

• Target A: Substantially reduce global disaster mortality by 2030.
• Target B: Substantially reduce the number of affected people globally by 2030.
• Target C: Reduce direct disaster economic loss in relation to global gross domestic product (GDP) by 2030.
• Target D: Substantially reduce disaster damage to critical infrastructure and disruption of basic services, among them health and educational facilities.
• Target E: Substantially increase the number of countries with national and local disaster risk reduction strategies.
• Target F: Substantially enhance international cooperation to developing countries through adequate and sustainable support.
• Target G: Substantially increase the availability of and access to multi-hazard early warning systems and disaster risk information.
