Introduction
India’s Ethanol Blending Programme (EBP) has emerged as an important component of the country’s strategy to reduce dependence on imported crude oil, diversify farmers’ income and promote cleaner fuels. Ethanol is largely produced from agricultural feedstocks, particularly sugarcane and its by-products.
However, the growing use of sugarcane for ethanol has also brought an important policy dilemma to the forefront:
Can India simultaneously pursue higher ethanol blending, maintain the economic viability of the sugar sector and ensure adequate food availability?
The issue is significant because sugarcane is a water-intensive crop, while sugar itself is an important food commodity. Therefore, policies that encourage diversion of sugarcane and sugar-derived products towards ethanol must be balanced against the requirements of food security, water security and farmer livelihoods.
1. Why is Ethanol Important for India?
India is heavily dependent on imported crude oil to meet its transport-energy requirements. This creates vulnerabilities arising from:
- International crude oil price fluctuations
- Geopolitical conflicts
- Exchange-rate movements
- Disruptions in global energy supply chains
- High import expenditure
Ethanol provides an opportunity to partially substitute petrol with a domestically produced renewable fuel.
The Ethanol Blended Petrol (EBP) Programme therefore serves multiple objectives:
Energy security → Import substitution → Farmer income → Sugar-sector stabilisation → Lower emissions
Ethanol also has the advantage of being compatible with India’s existing agricultural economy because it can be produced from several feedstocks.
2. The Sugar–Ethanol Connection
The relationship between sugar and ethanol is particularly important because sugarcane can be converted into either sugar or ethanol.
A simplified representation is:
Sugarcane

Juice / Molasses / Other sugar intermediates

Sugar production Ethanol production
This creates a degree of competition between food use and fuel use.
When sugar prices are weak and mills accumulate surplus stocks, diverting a part of sugarcane-derived material towards ethanol can help:
- Reduce surplus sugar
- Improve sugar-mill cash flows
- Enable timely payment of farmers
- Create an additional market for sugarcane
- Reduce the need for government intervention in surplus disposal
Thus, ethanol is not merely an energy policy. It has become an important instrument of agricultural and sugar-sector policy.
3. How Ethanol Helps the Sugar Sector
The Indian sugar industry has historically faced a structural problem of cyclical surplus production.
When sugarcane production rises substantially:
Higher cane availability → Higher sugar production → Surplus stocks → Lower sugar prices → Financial stress on mills → Delayed cane payments to farmers
Ethanol provides an alternative outlet.
Instead of converting the entire available cane into sugar, a portion can be diverted towards ethanol production.
This can help create a more balanced market:
Sugarcane → Sugar + Ethanol
rather than:
Sugarcane → Sugar alone
The diversification of output can therefore improve the financial sustainability of sugar mills.
4. But Where Does Food Security Enter the Picture?
The concern arises when diversion towards ethanol becomes sufficiently large to affect the availability of sugar or other agricultural resources.
Food security has several dimensions:
Availability + Accessibility + Affordability + Stability
Therefore, food security is not simply about producing more food. It also involves ensuring that adequate quantities of essential commodities remain available at affordable prices.
If agricultural resources are increasingly allocated towards fuel production, a policy question emerges:
How much agricultural production should be diverted from food to fuel?
This becomes especially important in a country where the majority of ethanol feedstocks ultimately depend on land, water and agricultural inputs.
5. Sugarcane: The Water Dimension
The ethanol debate cannot be separated from the question of water security.
Sugarcane is a relatively water-intensive crop. Large-scale cultivation can therefore place considerable pressure on groundwater and irrigation resources, particularly in regions already facing water stress.
The issue is not simply:
Food vs Fuel
It is also:
Fuel vs Food vs Water
This is particularly relevant because India’s agricultural policy has historically encouraged cultivation of crops such as sugarcane in certain regions through assured markets, pricing mechanisms and industrial demand.
Thus, increasing ethanol demand can potentially reinforce the economic attractiveness of sugarcane cultivation.
This raises a broader policy question:
Should ethanol policy encourage greater production of sugarcane, or should it primarily promote the use of existing agricultural surpluses and alternative feedstocks?
6. The Importance of Feedstock Diversification
One of the most important ways to reduce the food-security dilemma is to diversify ethanol feedstocks.
Ethanol can be produced from different sources, including:
Sugar-based feedstocks
- Sugarcane juice
- Sugar syrup
- Molasses
- Other sugar intermediates
Grain-based feedstocks
- Maize
- Certain other grains
Advanced feedstocks
- Agricultural residues
- Cellulosic biomass
- Other lignocellulosic materials
This creates an important policy opportunity.
Instead of depending excessively on sugarcane-based ethanol, India can gradually move towards a diversified feedstock basket.
Policy principle
Diversification of feedstocks → Reduced pressure on sugarcane → Greater flexibility → Better food-security management
7. The Food-Fuel Debate Should Not Be Oversimplified
It would be incorrect to conclude that ethanol blending automatically creates a food shortage.
The relationship is more complicated.
A food shortage can result from several factors, including:
- Production shocks
- Weather variability
- Crop diseases
- Water scarcity
- Supply-chain disruptions
- Export demand
- Hoarding and speculative behaviour
- Storage and distribution constraints
- Government procurement and stock policies
Similarly, ethanol can sometimes strengthen agricultural incomes rather than undermine food security.
For example, if ethanol demand improves the financial health of sugar mills, it can facilitate timely payments to sugarcane farmers.
Therefore, the real policy challenge is not choosing between ethanol and food security.
It is about designing an ethanol programme that remains compatible with long-term food, water and livelihood security.
8. The Central Policy Dilemma
The issue can be understood through four competing objectives:
| Objective | Policy requirement |
|---|---|
| Energy security | Increase domestic ethanol availability |
| Farmer welfare | Maintain remunerative agricultural markets |
| Sugar-sector stability | Reduce structural sugar surpluses |
| Food & water security | Prevent excessive diversion and resource stress |
The challenge is that these objectives do not always move in the same direction.
For instance:
Higher ethanol demand
↓
Greater demand for sugarcane-derived feedstocks
↓
Better returns for the sugar sector
BUT
↓
Potential increase in water-intensive cultivation
↓
Greater pressure on agricultural resources
Therefore, the policy must focus on optimising the entire system, rather than maximising any single objective.
9. What Should India Do?
① Promote feedstock diversification
India should reduce excessive dependence on a single crop or feedstock.
Greater use of maize, agricultural residues and advanced biofuels can provide flexibility while reducing pressure on sugarcane.
② Follow a flexible ethanol policy
Ethanol procurement should respond to the prevailing situation in agricultural markets.
During periods of sugar surplus, greater diversion can help stabilise the sugar sector.
During periods of tight sugar availability, diversion can be calibrated accordingly.
Thus:
Surplus year → Greater flexibility for ethanol
Shortage year → Greater priority to food availability
③ Integrate ethanol policy with water policy
The location of feedstock production matters.
India should increasingly evaluate crops not only on the basis of economic returns per hectare, but also on:
- Water consumed
- Water productivity
- Regional groundwater conditions
- Climate resilience
- Nutrient requirements
The concept of “more crop per drop” should be extended to biofuel policy as well.
④ Encourage second-generation ethanol
Second-generation (2G) ethanol produced from agricultural residues offers a particularly important opportunity.
It can convert materials such as crop residues into fuel, thereby:
- Reducing dependence on food crops
- Creating additional value from agricultural waste
- Supporting rural income
- Reducing residue-burning pressures
- Improving the sustainability of the biofuel transition
⑤ Maintain food-security safeguards
Ethanol policy should remain responsive to changes in:
- Sugar stocks
- Foodgrain availability
- Prices
- Domestic consumption
- Agricultural production
- Water availability
The government therefore needs sufficient policy flexibility to calibrate diversion of agricultural commodities between food and fuel uses.
10. The Way Forward: From “Food vs Fuel” to “Food + Fuel + Farmer + Water”
The debate should move beyond the simplistic question of whether ethanol is good or bad for food security.
The more appropriate question is:
What kind of ethanol economy does India want to build?
A sustainable biofuel strategy should simultaneously seek:
Energy security
＋
Farmer income security
＋
Sugar-sector stability
＋
Food security
＋
Water security
＋
Environmental sustainability
This requires a transition from a sugarcane-centric ethanol strategy towards a diversified and resource-efficient biofuel ecosystem.

Conclusion
India’s ethanol programme represents an important intersection of energy, agriculture, industry and environmental policy.
Ethanol can reduce dependence on imported fossil fuels and provide an additional market for agricultural produce. It can also help address the structural problem of sugar surpluses and strengthen the financial position of sugar mills.
However, an expansion of ethanol cannot be evaluated only through the lens of petrol blending targets. Water availability, food security, regional agricultural conditions and the sustainability of feedstock production must also be considered.
The way forward is therefore not to abandon ethanol, but to make the programme more diversified, flexible and resource-efficient.
India’s long-term objective should be to build a biofuel economy in which food is not sacrificed for fuel, farmers are not sacrificed for energy security, and water resources are not sacrificed for either.
The real goal should be: Food security + Energy security + Farmer prosperity + Water sustainability.
