"Water Resources Are Both an Asset and a Source of Conflict in South Asia." Examine This Statement Giving Examples — UPSC Mains 2026 GS1
A complete, examiner-standard 150-word model answer for the UPSC Mains 2026 GS Paper 1 question on South Asian water resources — with pointer-based structure, a river-basin dispute table, static core content, and the Indus Waters Treaty 2025–26 current affairs linkage.
UPSC Mains 2026 GS Paper 1 asked candidates to examine, with examples, the statement that water resources are both an asset and a source of conflict in South Asia, within a strict 150-word limit. Below is a full model answer in pointer-and-table format, along with a static-portion refresher and the relevant 2025–26 current affairs hook.
"Water resources are both an asset and a source of conflict in South Asia." Examine this statement giving examples. (150 words)
Model Answer
Introduction
South Asia's major rivers — the Indus, Ganga, Brahmaputra and their tributaries — sustain over a billion people through irrigation, drinking water and hydropower, yet their shared, transboundary nature has repeatedly turned them into flashpoints between riparian states.
Body
As an Asset
- Irrigation for 300+ million in the Indus basin alone
- Hydropower — Bhutan, Nepal, J&K projects
- Drinking water & fisheries livelihoods
- Basis for cooperative treaties & trade
As a Conflict Source
- Upstream-downstream trust deficit
- Treaties suspended or unresolved
- Dam-building disputes & data denial
- Water framed as strategic leverage
| River Basin | Countries | Cooperative Mechanism | Recent Flashpoint |
|---|---|---|---|
| Indus | India–Pakistan | Indus Waters Treaty, 1960 | Held in abeyance since April 2025; India rejected the Court of Arbitration's May 2026 award |
| Ganga | India–Bangladesh | Ganga Water Treaty, 1996 (Farakka) | Unresolved Teesta river sharing remains a persistent irritant |
| Kosi / Gandak / Mahakali | India–Nepal | 1954 / 1959 / 1996 treaties | Disputes over flood-control barrage maintenance and treaty review |
| Brahmaputra | India–China–Bangladesh | Expert-Level Mechanism (data-sharing only) | China's upstream mega-dam plans on the Yarlung Tsangpo, no binding treaty |
- Economic lifeline — the Indus system alone irrigates land supporting over 300 million people across India and Pakistan; the Ganga-Brahmaputra-Meghna basin sustains agriculture for much of eastern South Asia.
- Durable cooperation — the Indus Waters Treaty (1960) and the Ganga Water Treaty (1996) demonstrated, for decades, that shared rivers could anchor cooperation even amid broader hostility.
- India-Pakistan — India placed the Indus Waters Treaty in abeyance after the April 2025 Pahalgam attack; Pakistani officials have called any water disruption an "act of war," and the dispute remains unresolved through 2026.
- India-Bangladesh and India-Nepal — the Teesta sharing formula remains unsettled with Bangladesh, while flood-control and barrage-maintenance disputes periodically strain relations with Nepal.
- India-China — the absence of a binding treaty on the Brahmaputra, combined with China's upstream dam-building, leaves India dependent on a thin, non-binding data-sharing mechanism.
- Upstream-downstream asymmetry — upper riparian states control infrastructure and data, structurally disadvantaging downstream neighbours regardless of treaty text.
- Securitisation of water — water sharing is increasingly linked to unrelated security and terrorism disputes, as seen in the 2025 IWT suspension, eroding water's status as a purely technical, cooperative issue.
Conclusion
Water remains South Asia's most vital shared asset, but its transboundary nature and the region's weak institutional architecture mean it can just as easily be weaponised — making basin-wide, depoliticised water governance essential for the region's stability.
Indus Waters Treaty (1960): brokered by World Bank; eastern rivers (Ravi, Beas, Sutlej) to India, western rivers (Indus, Jhelum, Chenab) to Pakistan; Permanent Indus Commission for dispute resolution.
Ganga Water Treaty (1996): governs dry-season flow sharing at the Farakka Barrage between India and Bangladesh. Kosi Agreement (1954) and Gandak Agreement (1959): India-Nepal flood-control and irrigation arrangements. Mahakali Treaty (1996): covers the Pancheshwar multipurpose project. No binding India-China river treaty exists; cooperation is limited to an Expert-Level Mechanism for hydrological data-sharing.
Answer Writing Tips for This Question
- The question explicitly says "giving examples" — a table mapping river basin → countries → treaty → flashpoint is the fastest way to prove breadth without burning word count on prose.
- Cover more than just India-Pakistan — examiners reward candidates who bring in Bangladesh, Nepal and China examples, showing South Asia-wide awareness rather than a single bilateral lens.
- Use the asset-vs-conflict comparison panel to visually prove both halves of the statement are addressed before the prose even begins.
- Anchor the conflict half with the Indus Waters Treaty's 2025–26 suspension — it's the most significant, exam-relevant development in South Asian water politics in years.
- Name the underlying structural driver (upstream-downstream asymmetry) rather than only listing disputes — this is what turns a list into an "examination."
- Close with a forward-looking institutional point (basin-wide governance) since "examine" questions are rewarded for going beyond description into assessment.
