Challenges in Watershed Management: Addressing Land and Water Scarcity in India

India is home to nearly 18% of the world’s population but holds only about 4% of the planet’s freshwater resources. At the same time, its agricultural land – though vast in absolute terms – is under severe and growing pressure. The combination of a shrinking per capita land base and rapidly declining per capita water availability is not a future projection anymore; it is an ongoing reality that directly threatens the country’s food security. Understanding these twin challenges – and why watershed management is central to addressing them – is essential for anyone working in or studying India’s agrarian landscape.

The shrinking land base: less farmland, more mouths to feed 🔗

India currently has around 140 million hectares of agricultural land, roughly 42-44% of its total geographical area. While this sounds substantial, the per capita picture is far more alarming. India’s per capita land availability is approximately 0.25 hectares per person, compared to the global average of about 2.3 hectares per person. This gap alone signals how intensively India’s land must work to sustain its population.

The situation is made worse by the ongoing fragmentation of farm holdings. According to a NABARD survey, the average landholding size fell from 1.08 hectares in 2016-17 to just 0.74 hectares in 2021-22 – a decline of about 31% in just five years. Today, over 85% of Indian farmers operate on plots smaller than 2 hectares, which creates serious barriers to mechanisation, irrigation investment, and the adoption of sustainable farming practices.

On top of fragmentation, agricultural land is actively being lost. FAO estimates suggest India loses nearly 2 million hectares of cultivable land annually to urban sprawl and non-agricultural uses. Rapid urbanisation, industrial expansion, and infrastructure development are converting fertile peri-urban land at an accelerating pace. Meanwhile, nearly 30% of India’s land – about 97 million hectares – is already degraded, reducing its productive capacity even where it technically remains agricultural. The pressure on what remains is thus intensifying from multiple directions simultaneously.

The water crisis: projections that demand urgent action 🔗

India’s water situation follows a similarly steep downward curve. Per capita water availability in India stood at 5,200 m³ in 1951. By 2010, it had fallen to 1,588 m³. Under international norms, a country is classified as “water stressed” when per capita availability drops below 1,700 m³ per year and “water scarce” below 1,000 m³. India crossed into water-stressed territory some years ago and according to the Central Water Commission, per capita availability is expected to reach 1,228 m³ by 2050 – dangerously close to the scarcity threshold.

The demand side of this equation makes matters worse. Total water demand in India is estimated to increase by around 34% by 2025 and over 78% by 2050, eventually exceeding the country’s total replenishable water capacity of 1,123 billion cubic metres. Agriculture is by far the largest consumer, accounting for around 90% of all water withdrawals. Industrial and domestic sectors are also growing their demands rapidly – domestic water demand alone is projected to rise from 85 litres per capita per day in 2000 to 170 litres per capita per day by 2050, while total industrial water demand is expected to reach 161 billion cubic metres by the same year.

The groundwater problem 🔗

Much of India’s current agricultural productivity depends on groundwater – a resource that is being depleted far faster than it is being replenished. Close to 90% of groundwater consumed in India is used for irrigation, and the consequences of this over-dependence are visible across the country. In Punjab and Haryana, groundwater depletion surpasses natural replenishment rates by 65% and 34% respectively, driven largely by the water-intensive rice-wheat cropping system introduced during the Green Revolution. Research published in Science Advances warns that groundwater depletion could reduce cropping intensity by as much as 20% nationwide – and by as much as 68% in the most severely depleted regions – with serious implications for national food production.

A key aggravating factor is that about 70% of India’s surface water is already polluted, which increases the pressure on groundwater as the primary source for both irrigation and drinking. The spatial mismatch between where water is available and where population is concentrated makes the situation even more unequal – less water exists where more people live.

Multi-sector pressure: agriculture is not alone 🔗

While agriculture dominates water consumption, the pressure from other sectors is rising sharply and cannot be ignored in any long-term resource planning exercise. Public health is a growing concern: according to the WHO, half of India’s disease burden is water-related, and providing safe drinking water to all remains a major unmet challenge. Over 10% of the population still lacks access to clean drinking water, according to national health surveys.

Industrial growth adds another dimension. India’s rapid economic expansion has made industry a significant and growing claimant on both freshwater and land resources. Conversion of fertile agricultural land for industrial use, along with industrial effluent contaminating water bodies, creates a feedback loop that further degrades the resource base available to farmers. The net effect is that agriculture is being squeezed from multiple sides – competing for water with cities and industries, losing land to urbanisation, and simultaneously expected to feed a population projected to reach 1.64 billion by 2050.

Why watershed management is part of the solution 🔗

Given these compounding pressures, there is no single technological fix. What is needed is a systems-based approach that addresses land, water, and farming productivity together. This is precisely what well-designed watershed management programmes are intended to provide. A watershed is not only a hydrological unit but also a socio-ecological entity that determines food, social, and economic security. Managing it well means managing the relationship between rainfall, soil, vegetation, and communities as an integrated whole.

Rainwater harvesting and groundwater recharge 🔗

India receives approximately 3,000 billion cubic metres of monsoon rainfall annually, yet only a fraction is effectively stored or allowed to recharge groundwater. With agriculture accounting for about 70% of the country’s water consumption, efficient water management through rainwater harvesting emerges as a sustainable solution for addressing water scarcity and enhancing agricultural productivity. Watershed management programmes deploy check dams, farm ponds, percolation tanks, contour bunds, and gully plugs to slow down runoff, allow water to seep into the ground, and extend the availability of water well beyond the monsoon season.

By slowing down the flow of water across the surface, these structures increase the possibility of percolation into the ground, which in turn raises the water table and prolongs the flow of water in drainage lines. The government’s Integrated Watershed Management Programme (IWMP) supports soil and water conservation, afforestation, and the construction of small-scale water harvesting structures at scale, targeting some of the most water-stressed rural communities in the country.

Improving productivity on limited land 🔗

The fundamental challenge in India is to produce more food from less land and less water. Watershed management directly supports this goal by improving soil health, reducing erosion, and enabling year-round cultivation. Watershed management can result in increased water availability for small farmers, improving food security, employment opportunities, and reduced seasonal migration.

A concrete example comes from a study of the Kumbharwadi watershed in Maharashtra, conducted by the World Resources Institute and the Watershed Organisation Trust (WOTR). Before watershed development interventions began, agricultural production was only possible for a single season of three to four months, prompting many villagers to migrate for work. After sustained watershed management over more than a decade, the programme delivered over $9 million worth of food security and water management benefits to the community. Farmers could cultivate across multiple seasons, groundwater levels recovered, and women’s self-help groups were able to access micro-finance for farm equipment – illustrating how water security and livelihoods are deeply interlinked.

Integrated farming systems and crop diversification 🔗

Watershed management also enables a shift away from water-guzzling monocultures. With increased water availability through rainwater harvesting, farmers can diversify their crop choices and cultivate high-value and water-efficient crops, contributing to improved food security and income. This is particularly important given that rice, wheat, and sugarcane – three of the most water-intensive crops – together consume over 50% of India’s total irrigation water, according to NABARD estimates. Promoting integrated farming systems that combine crops, horticulture, livestock, and agroforestry within a watershed framework can increase output per unit of land and water, while also spreading income risk for smallholder farmers.

Reducing water-intensity in agriculture also has a direct bearing on India’s food import dependency. If groundwater depletion is allowed to reduce cropping intensity as projected, India’s ability to be self-sufficient in food grains will be severely compromised. India currently exports 25 billion cubic metres of virtual water annually through food trade, even as domestic taps run dry – a paradox that reflects the disconnect between agricultural policy and water resource management. Watershed-based approaches that improve water use efficiency can help close this gap by sustaining domestic production without accelerating aquifer depletion.

Policy and institutional response 🔗

India has not been inactive on these fronts. The government has launched several programmes targeting watershed health and water security. The Integrated Watershed Development Programme (IWDP), launched in 1989, focuses on improving land productivity and socio-economic conditions in watershed areas. The National Watershed Development Project for Rainfed Areas (NWDPRA) promotes soil and water conservation in rain-fed farming zones. More recently, the Jal Shakti Abhiyan and Jal Jeevan Mission have expanded the focus to include rural drinking water security and source sustainability alongside agricultural use. Schemes such as AMRUT 2.0, launched in 2021 with a dedicated outlay for urban water supply, and the Jal Shakti Abhiyan: Catch the Rain initiative have been designed to make Indian cities and rural areas more water secure.

However, the scale of the challenge means that programme-level interventions need to be matched with deeper reforms – in how agricultural subsidies are structured, how groundwater rights are defined and enforced, how land use is governed at the local level, and how communities are empowered to manage their own watershed resources. Policies that reduce demand for groundwater – such as switching to less water-intensive crops – along with the adoption of water-saving irrigation technologies like sprinkler and drip systems, are essential complements to watershed development.

Looking ahead: productivity with sustainability 🔗

The convergence of declining per capita land and water availability with rising demand from agriculture, industry, and public health means India faces a genuinely difficult resource arithmetic. With per capita water availability projected to fall to as low as 1,140 m³ per year by 2050, and farmland continuing to fragment and degrade, the country cannot afford to continue on a business-as-usual trajectory. Watershed management – combining rainwater harvesting, soil conservation, groundwater recharge, and integrated farming – offers a proven pathway to increase agricultural productivity within tightening resource limits. It is not a silver bullet, but it is a foundational strategy for building the kind of resilient rural economy that India’s food security will increasingly depend on in the decades ahead.

What do you think? Given that both land and water per capita availability are on a steep downward trajectory, should India prioritise water-use efficiency in agriculture above expanding irrigated area? And can community-led watershed management programmes scale up fast enough to make a meaningful difference before resource thresholds become critical?
