Integrated Water Resource Management in the Indian context

Integrated Water Resource Management (IWRM) is a process that promotes the coordinated development and management of water, land, and related resources in order to maximise economic and social welfare equitably — without compromising the sustainability of vital ecosystems. As hydrologist Malin Falkenmark defined it, IWRM emphasises the integration of land, water, and ecosystems, aiming to balance social equity, economic efficiency, and environmental sustainability. Crucially, it calls for integration across temporal, sectoral, and spatial scales — breaking the silo mentality that has historically fragmented water governance.

For India, IWRM is not an abstract academic concept but a pressing operational necessity. The country hosts the world's largest population, an economy in which agriculture accounts for over 70% of freshwater withdrawals, rapid urbanisation, and intensifying climate variability — all converging on a finite and unevenly distributed resource base. Water resource management is one of the most intractable challenges for planners and policymakers, given the limited supply, continuously growing demand, and declining quality of freshwater. Without an integrated lens, isolated interventions in one sector routinely creates externalities in another: subsidised electricity drives groundwater over-extraction, canal irrigation waterlogging suppresses productivity, and untreated urban sewage renders downstream rural water sources unsafe.

India's water situation is formally characterised as one of stress — the threshold just above scarcity. The Central Water Commission's Assessment of Water Resources of India 2024 reveals that India's average annual per capita water availability from 1985 to 2023 stands at approximately 1,513 cubic metres, placing it squarely in the "water stress" category under the Falkenmark Indicator, which defines stress as below 1,700 m³. More alarmingly, India's per capita annual water availability is projected to fall further to 1,367 m³ by 2031 — edging towards absolute scarcity.

Key Numbers at a Glance
Per capita water availability (2024): ~1,513 m³/year · Projected 2031: ~1,367 m³/year · Stress threshold: 1,700 m³ · India's share of global freshwater: ~4% · Share of global population: ~18%

These national averages mask profound regional disparities. The water sector faces increasing variability and unpredictability due to climate change, compounded by inadequate storage and distribution infrastructure and the insufficient integration of climate resilience into water management policies — as highlighted in the IPCC's Sixth Assessment Report. Extreme weather events, rising temperatures, erratic monsoons, and sea level rise threaten agriculture, industry, ecosystems, and overall water security simultaneously, making a fragmented, sector-by-sector response entirely inadequate.

India has formulated three National Water Policies — in 1987, 2002, and 2012 — each progressively incorporating international water management norms. The National Water Policy 2012 (NWP 2012) was the most explicit in embracing IWRM principles. It promoted the river basin as the unit of planning, called for the creation of River Basin Organisations (RBOs), and, emphasised climate change adaptation, water use efficiency, community participation, and the river basin management approach.

However, the policy's implementation record has drawn fierce criticism. NWP 2012 faced limitations, including inordinate delays in creating River Basin Agencies, inadequate implementation of policy recommendations, intractable inter-state disputes, over-optimistic water availability estimates, and a failure to consider India's ancient water cultures and the irrigation-energy nexus. The crucial "subsidiarity principle" — devolving planning to the lowest appropriate level — was largely absent.

"All versions of India's National Water Policies have promoted ideas that are un-implementable in the Indian context, driven by fashionable ideas paraded in international water seminars." — China Water Risk Review

Critics have further noted that NWP 2012 gave the impression that IWRM principles were to be implemented through a centralised, top-down approach — an erroneous reading that paradoxically justified the controversial and expert-contested proposal for Interlinking of Rivers. A genuinely operational IWRM framework requires discrete River Basin Agencies before any integration can occur, and not a single multi-state RBO has yet been created. India is widely regarded as overdue for a fourth National Water Policy.

IWRM rests on four interconnected pillars: the enabling environment (policies, legislation, and financing); institutions and participation (stakeholder engagement, gender equity, and decentralisation); management instruments (water allocation, pollution control, and demand management); and financing (cost recovery and public investment). SDG Indicator 6.5.1 tracks IWRM implementation across precisely these four dimensions — enabling environment, institutions and participation, management instruments, and financing.

In the Indian context, each pillar demands specific adaptations. The enabling environment must reconcile water as a concurrent subject — governed jointly by the Union and states — with the basin-level planning logic of IWRM. Institutions must go beyond token participation and genuinely empower Panchayati Raj Institutions and Water User Associations. A practical IWRM approach should advocate for more efficient, context-specific, and locally tailored solutions that emphasise decentralised management.

The financing pillar remains perhaps the most neglected. Water pricing in India is almost universally below cost-recovery levels, creating massive fiscal drains and perverse incentives for wasteful use. A reformed IWRM architecture for India must simultaneously protect the right to water for the poor while introducing progressive pricing signals for commercial and large-scale agricultural users — a politically sensitive but technically manageable reform.

Groundwater is India's most critical water asset, and its condition is both alarming and slightly improving. The Ministry of Jal Shakti's Dynamic Ground Water Resource Assessment Report 2024 shows that total annual groundwater recharge stands at 446.90 Billion Cubic Metres (BCM), while annual extraction is 245.64 BCM — giving an overall stage of groundwater extraction of 60.47%. This headline number sounds comfortable, but it masks dangerous regional concentrations.

Groundwater Assessment 2024 (Ministry of Jal Shakti):
Total recharge: 446.90 BCM · Extractable resource: 406.19 BCM · Annual extraction: 245.64 BCM · Safe units: 73.4% (up from 62.6% in 2017) · Over-exploited units: 11.13% (down from 17.24% in 2017)

Over-exploitation is concentrated in northwest India — Punjab, Haryana, Delhi, and western Uttar Pradesh — as well as western arid regions and peninsular crystalline belts, creating stark regional development inequalities. Groundwater supplies 85% of rural and approximately 50% of urban drinking water, making depletion a direct human security concern. Quality problems compound quantity stress: the 2024 Annual Groundwater Quality Report flags fluoride as a major contaminant, with over 9% of samples exceeding safe limits, while arsenic contamination affects key alluvial aquifers.

The modest improvements in groundwater since 2017 are encouraging and partly attributable to government recharge programmes — but studies show that Punjab and Haryana together lost approximately 64.6 BCM of groundwater over seventeen years, and flagship recharge schemes like the Atal Bhujal Yojana have utilised barely 4% of their annual allocation in some states, pointing to persistent implementation failure beneath the policy optimism.

Agriculture is both the lifeblood of India's rural economy and the dominant driver of its water crisis. Irrigation accounts for over 80% of India's total water use, and much of it is inefficient — flood irrigation methods lose large fractions to evaporation, and crops like paddy and sugarcane cultivated in water-scarce regions are sustained only by heavily subsidised power for groundwater pumping.

A Council on Energy, Environment and Water study finds that if agricultural practices such as micro-irrigation and mulching are adopted alongside policy reforms like water auditing and volumetric pricing, nearly 20% of irrigation water could be saved by 2030 — rising to 47% by 2050 under a rigorous water-saving scenario. An ICRIER study identifies a structural governance problem: minimum support price assurances for water-intensive crops like rice, wheat, and sugarcane create highly skewed incentive structures that encourage cultivation of precisely the crops that stress water resources most.

IWRM-consistent agricultural water reform requires integrating water, food, and energy governance as a nexus, not as isolated silos. Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), with its "More Crop Per Drop" mandate, moves in this direction by promoting micro-irrigation — from 2015–16 until December 2024, an area of 94.36 lakh hectares has been covered under micro-irrigation through the PDMC scheme. But the deeper structural reforms — shifting crop patterns, decoupling power subsidies from water extraction, and basin-level water budgeting — remain politically contested and are yet to be fully operationalised.

River Basin Organisations (RBOs) are the institutional centrepiece of IWRM. By managing all water-related decisions at the level of the hydrological unit — the river basin — rather than at administrative boundaries, RBOs can reconcile competing demands, plan conjunctive use of surface and groundwater, and ensure equitable allocation across upstream and downstream users.

India's failure to establish functional multi-state RBOs is one of the most significant structural gaps in its water governance. Not a single multi-state RBO has been created in over thirty years since the first National Water Policy, and the enabling legislation suggested in NWP 2012 has not even been drafted, far less enacted. The reasons are deeply political: water is a state subject under India's Constitution, and states are understandably reluctant to cede planning and allocation authority to a supra-state body, especially where inter-state water disputes — over the Cauvery, Krishna, Mahanadi, and Ravi-Beas, among others — remain unresolved.

States should adopt an integrated river basin management approach to ensure basin-wise management activities, with administrative mechanisms clearly described and operationalised in collaboration with respective state and central government departments and community representatives, preventing overlap among existing departments. The International Water Management Institute continues to emphasise integrated surface and groundwater management and managed aquifer recharge as critical strategies for building climate resilience — both of which require the institutional platform that RBOs would provide.

India's IWRM-oriented programmatic landscape has expanded considerably since 2015, with several interlocking schemes addressing different dimensions of the challenge. The Jal Jeevan Mission (JJM), launched in 2019, is the most ambitious: it is envisioned to provide safe and adequate drinking water through individual household tap connections to all rural households, with source sustainability measures — including recharge, reuse through grey water management, and rainwater harvesting — as mandatory elements. 

As of early 2025, over 15.44 crore additional rural households have been provided with connections, covering approximately 79.74% of all rural households, though the mission has been extended to 2028 to achieve full coverage.

The Atal Bhujal Yojana (Atal Jal) targets demand-side groundwater management in 8,203 gram panchayats across seven water-stressed states. The Jal Shakti Abhiyan, a mass mobilisation campaign, drives water harvesting and conservation. Under Jal Shakti Abhiyan: Catch the Rain 2025, over 3.96 lakh water conservation and rainwater harvesting works, 1.45 lakh reuse and recharge structures, 71,364 traditional water body renovations, and 6.15 lakh watershed development works were completed. JJM works in tandem with MGNREGS, Swachh Bharat Mission, and PMKSY, employing IoT, SCADA systems, GIS mapping, and real-time dashboards to monitor water quality and distribution — a tangible step towards data-driven integrated management.

One of the most glaring lacunae in India's successive National Water Policies has been the near-total neglect of the country's extraordinarily rich tradition of community-managed water systems. Step wells (baolis), tank networks (eries), check dams (johads), kunds, khatris, virdas, and countless other regional innovations represent millennia of distributed, adaptive water management, precisely what IWRM theory advocates. The Rajasthan johad revival, the tank systems of Tamil Nadu managed by Oorani committees, and the phad irrigation of Maharashtra are just a few examples of functional, community-led IWRM.

India's National Water Policy 2012 failed to consider the country's ancient water cultures — a significant omission that critics have repeatedly flagged. Modern IWRM frameworks tend to view water governance as a technocratic challenge amenable to engineering and pricing solutions, missing the governance lessons embedded in customary institutions. Reviving and formally recognising traditional water bodies, integrating indigenous water knowledge into basin planning, and protecting the legal status of customary water rights are not backwards-looking sentimentalism — they are crucial supplements to any technically robust IWRM programme.

IWMI's grassroots initiatives in India consistently demonstrate that local knowledge and active community participation are vital to achieving long-term water security and resilience — engaging communities not just in the adoption of new technologies but also in the stewardship of water resources is central to any lasting solution.

Technology is increasingly a force multiplier for IWRM, and India is beginning to harness it systematically. Remote sensing and GIS have enabled basin-level mapping of water bodies, recharge zones, and pollution hotspots. IoT-enabled sensors allow near-real-time tracking of reservoir levels, groundwater tables, and water quality parameters. The Central Ground Water Board now operates over 15,200 monitoring locations, providing the data density necessary for evidence-based management. Integrating AI, particularly in intelligent water management systems, presents promising implications for improving water supply efficiency and optimising service delivery processes.

IWMI's Water Productivity Atlas — a pioneering tool offering insights into water productivity across more than 600 districts, covering over 30 crops — allows policymakers to analyse spatial and temporal variations in water use and model crop diversification scenarios to reduce groundwater footprints. Such tools can, for example, quantify the water savings from shifting rice cultivation areas to sunflowers or vegetables — translating hydrological complexity into actionable policy guidance.

Open data platforms are equally important. The India-WRIS (Water Resources Information System) provides basin-level data accessible to researchers and civil society. However, data quality, interoperability between state and central systems, and the last-mile digital divide remain persistent constraints. A genuine IWRM architecture requires that data flow not just upward to central planners but downward and laterally — to farmers, village water committees, and district administrators who make the real-time decisions that determine water outcomes.

The most fundamental challenge is constitutional. Water is a State List subject under Schedule VII of the Indian Constitution, meaning states hold primary jurisdiction. The Central Government's role is legally confined to inter-state disputes and regulation of international rivers. This creates a structural misfit with IWRM's demand for basin-level governance, since major Indian rivers cross multiple state boundaries. The Cauvery dispute between Karnataka and Tamil Nadu, spanning over a century of litigation, illustrates how inter-state water politics can paralyse even modest coordination efforts.

Several challenges persist in India's water management landscape, including delays in establishing River Basin Authorities, inadequate implementation of recommended policies, intricate inter-state disputes, overly optimistic assessments of annual water availability, and insufficient inclusion of multi-stakeholder participation in policy formulation. Social sustainability — ensuring water equity for marginalised communities, women, and Scheduled Castes and Tribes — receives inadequate attention in existing frameworks.

Fragmentation across ministries compounds the problem. Water-related functions are distributed between the Ministry of Jal Shakti, the Ministry of Agriculture, the Ministry of Environment, Forest and Climate Change, the Ministry of Power, and numerous state departments — each with its own budget lines, performance metrics, and institutional interests. The dynamic nature of IWRM requires continuous updates, enhancements, and revisions to adapt to increasingly complex governance challenges — a recognition that no single policy document, however comprehensive, can substitute for adaptive institutional capacity.

The path forward for IWRM in India is neither simple nor linear, but its broad contours are increasingly clear. Four priority actions stand out. First, India urgently needs a new National Water Policy — the fourth — that corrects the top-down misreading of IWRM embedded in NWP 2012, anchors basin-level planning in law, and creates a genuine enabling environment for RBO formation with federal buy-in. Revamping water governance requires a policy architecture that can integrate land, water, and ecosystem concerns across the full complexity of India's river basins, including the adaptation pressures of glacial melt and sea level rise.

Second, agricultural water reform must become a political priority. The convergence of PMKSY, Atal Bhujal Yojana, and JJM points in the right direction, but the incentive structures — crop procurement policies, power subsidies, and weak groundwater regulation — need far more fundamental revision. Integrating IWRM and climate change adaptation into agricultural policy requires simultaneous attention to water auditing, volumetric pricing, and crop diversification frameworks, recognising the inherent resource nexus challenges where governance of water, food, and energy inevitably conflict.

Third, community participation must be substantive, not symbolic. Integrating Jal Jeevan Mission with Atal Bhujal Yojana for source sustainability and institutionalising community-led water budgeting approaches in villages would embed the IWRM principle of subsidiarity at the grassroots level. Women, as India's primary water carriers and managers, must be central rather than peripheral participants.

Finally, the integration of technology — AI, remote sensing, IoT, and open data — must be pursued as an enabler, not a substitute, for governance reform. No dashboard replaces a functioning River Basin Authority. No satellite image replaces a negotiated water-sharing agreement between upstream and downstream farmers. The practical IWRM approach advocates for more efficient, context-specific, and locally tailored solutions — emphasising that decentralised management of water resources, administered in collaboration with state and central departments and community representatives, offers the most durable path towards water security. India has both the intellectual tradition and the institutional ambition to make IWRM work. The question is whether the political will can match the hydrological urgency.
