Key Highlights
- India’s disjointed water governance demands a Source‑to‑Sea overhaul.
- 2025’s International Year of Glacier Preservation underscores the urgency of linking upstream and downstream waters.
- The S2S framework marries freshwater and marine stewardship into one integrated continuum.
- Adopting S2S can curb pollution, safeguard glacial meltwater, and sustain marine biodiversity.
- Government layers—from local councils to national bodies—must be nested and synchronized.
Detailed Insights
Policy Gap and Climate Stress
Roughly 600 million Indians face water scarcity, threatening a 6 percent hit to GDP. 311 severely polluted river stretches were flagged by the CPCB. Groundwater depletion sits at 60.5 percent of extractable reserves, with Punjab, Haryana and Rajasthan exceeding 100 percent usage. Rising salinity and quality loss further compound the crisis.
Source‑to‑Sea in Context
The S2S concept emerged from the 2012 Manila Declaration and has been institutionalised by SIWI and IUCN. It aligns with SDG 6.5 and 14.1, promoting Integrated Water Resources Management and preventing land‑based marine pollution.
Governance Layers
India’s water commons span local, state, national and global tiers. Fragmentation hampers trans‑boundary coordination. A nested S2S model can unify policy, research and operation across these strata.
Case Illustrations
Delhi’s nutrient management pilot and the proposed Indo‑Gangetic Basin settlements programme demonstrate how S2S can harmonise regional planning, agriculture, and drinking‑water safety.
Key Concepts
- Source‑to‑Sea (S2S): A governance framework treating watershed, river basin and ocean as a single hydrological chain.
- Integrated Water Resources Management (IWRM): Coordinated development and management of water, land and related resources.
- Glacier Preservation: Efforts to protect glacial mass, reduce melt rates and secure downstream water streams.
- Marine Biodiversity Conservation: Safeguarding species and ecosystems from anthropogenic pressures.
- Hydro‑System Resilience: The capacity of interconnected water bodies to absorb climate shocks.
