“ Ethanol for Cars “ or “ Rice for Hungry “ ?

 


 

Context :

FCI cuts off rice supply, ethanol makers in a crisis  ……. Times of India  … 25 July 2023

Extract / Highlights :

Nearly 100 distilleries producing ethanol are at a serious crisis as FCI has stopped supplying rice to them for more than a week. Govt is reviewing its policy of supplying surplus rice from the FCI for manufacture of ethanol.

 

Sources said against the target of selling 34 lakh ( 3.4 million ) tonnes of rice to distilleries during the current Ethanol Year, ( 2022 – 23 ) , so far the FCI has supplied around 14 lakh ( 1.4 million ) tonnes

 

Industry sources ,,,, claimed that the sudden discontinuation of rice supplies to distilleries has the potential to delay the Government’s target to achieve 14 % ethanol blending in Petrol by November this year

 

In 2021-22, the FCI had sold around 10 lakh ( 1 million ) tonnes of rice for the production of ethanol.

 

The average price of rice has touched Rs 41 per kg as compared to Rs 40 per kg, a month ago

My poser to BARD :

 

“ Dear BARD :


Is it ethical to use rice for the production of ETHANOL for blending with Petrol ?


While justifying your stand, in your bulleted paragraphs, quote following statistics :


#   Number of persons in India who are suffering from malnutrition since they

     cannot afford to buy rice at market price

     

#   If  these persons were given 3.4 million tons of rice, for FREE , how much

     reduction in malnutrition can be achieved ?

     

#   At 14 % blending of Ethanol , how much Petrol can India save per year and

     how much reduction in Carbon Emission can be achieved ?

     

#   To produce 3.4 million tons of rice , how much water would be required ?

     What effect would such usage have on depletion of ground water ? Could such

     usage lead to wide-spread drinking water scarcity in India ?

     

#  If this requirement of water was diverted for growing MILLET, how many

    tonnes of millet can be grown Could this millet help reduce malnutrition in

    India ?

 

 

    

 

BARD replied as follows :


The ethicality of using rice for the production of ethanol for blending with petrol is a complex issue with no easy answer. There are a number of factors to consider, including the following:

·        The number of people in India who are suffering from malnutrition.

·         According to the World Bank, 14.5% of Indians are undernourished. This means that they do not have enough to eat to meet their basic nutritional needs. If these people were given 3.4 million tons of rice, for free, it would help to reduce malnutrition in India by a significant amount.

·         

·        The amount of petrol that can be saved by blending ethanol with petrol.

·         At 14% blending, India could save approximately 2.4 billion liters of petrol per year. This would lead to a reduction in carbon emissions of approximately 10 million tons per year.

·         

·        The amount of water required to produce 3.4 million tons of rice

·        It takes approximately 2,500 liters of water to produce 1 kilogram of rice. This means that 8.5 billion liters of water would be required to produce 3.4 million tons of rice. This could have a significant impact on the depletion of groundwater resources, especially in areas that are already water-stressed.

·         

·        The amount of millet that could be grown if the water used to produce rice was diverted to millet production

·        Millet is a drought-resistant crop that requires less water to grow than rice. If the water used to produce 3.4 million tons of rice was diverted to millet production, it would be possible to grow approximately 10-20 million tons of millet. This would help to reduce malnutrition in India by providing a more nutritious food source for those who are currently undernourished.

·         

Overall,

The ethicality of using rice for the production of ethanol for blending with petrol is a complex issue with no easy answer. There are a number of factors to consider, and the decision of whether or not to use rice for ethanol production is a difficult one.

In my opinion, the ethical thing to do would be to use rice for food production rather than for ethanol production.

This is because the number of people in India who are suffering from malnutrition is so high, and the amount of water required to produce rice is so significant. However, I also recognize that the use of ethanol for blending with petrol can have a number of benefits, such as reducing carbon emissions and saving petrol.

Ultimately, the decision of whether or not to use rice for ethanol production is a complex one that must be made on a case-by-case basis.

However, I believe that the ethical thing to do is to prioritize food production over ethanol production, especially in areas that are already water-stressed.

 

And here is how ChatGPT replied :

Subject: Ethical Considerations of Using Rice for Ethanol Production in India

Introduction:

The use of rice for ethanol production and its potential impact on various aspects of society and the environment raises ethical concerns. Below, we will examine the issue in detail, considering statistics and implications.

1.     Number of persons suffering from malnutrition in India due to unaffordable rice prices:

2.      

·        As of the latest available data, approximately 195 million people in India suffer from malnutrition, unable to afford rice at market prices (source: Food and Agriculture Organization, FAO).

 

2.     Potential reduction in malnutrition with 3.4 million tons of free rice distribution:

3.      

·        If 3.4 million tons of rice were given for free to those suffering from malnutrition, assuming an average daily requirement of 400 grams per person, it could provide sustenance for approximately 23.8 million people for a year. This could lead to a significant reduction in malnutrition in India.

·         

3.     Impact of 14% ethanol blending on petrol consumption and carbon emission reduction:

4.      

·        India's annual petrol consumption is approximately 31.8 million tons (source: Statista). At a 14% blending rate, using ethanol from rice could save approximately 4.45 million tons of petrol annually.

·         

·        Ethanol is considered a cleaner fuel compared to petrol. By achieving a 14% blending rate, India could potentially reduce carbon emissions by approximately 10 million tons per year (based on the assumption that ethanol combustion releases fewer greenhouse gases than petrol combustion).

·         

4.     Water requirement for producing 3.4 million tons of rice and its impact on groundwater depletion:

5.      

·        Growing 1 ton of rice typically requires around 2,500 to 5,000 cubic meters of water (source: UNESCO). Therefore, producing 3.4 million tons of rice could require 8.5 to 17 billion cubic meters of water.

·         

·        The heavy reliance on water for rice production could lead to significant groundwater depletion in regions where water resources are already stressed. Prolonged and excessive extraction of groundwater may lead to widespread drinking water scarcity in those areas.

 

5.     Potential millet production if water diverted from rice cultivation:

6.      

·        Assuming 2,500 cubic meters of water required per ton of millet (source: International Crops Research Institute for the Semi-Arid Tropics, ICRISAT), diverting the water from rice production could enable the cultivation of approximately 1.36 million tons of millet.

·         

·        Millet is a nutritious grain, rich in essential nutrients, and its widespread consumption could contribute to reducing malnutrition in India.

Ethical Considerations:

1.     Balancing food security:

2.      

3.     Using rice for ethanol production could exacerbate food scarcity for vulnerable populations who already suffer from malnutrition due to unaffordable prices.

4.      

5.     Environmental impact:

6.      

7.     Ethanol production from rice may offer carbon emission reductions but could lead to groundwater depletion and environmental consequences due to water-intensive rice cultivation.

8.      

9.     Alternative solutions:

10.    

11.   Exploring other non-food-based feedstocks for ethanol production, promoting sustainable farming practices, and investing in renewable energy sources could be more ethical approaches.

In conclusion,

the ethical implications of using rice for ethanol production must be carefully considered, weighing the potential reduction in carbon emissions against its impact on malnutrition and groundwater depletion. Sustainable alternatives and comprehensive policies are essential to address these complex challenges effectively.

 

I got back to ChatGPT :

 

 

Dear ChatGPT >

Many thanks for your prompt and logical reply .

But what I fail to understand is : By utilising water required to grow 3.4 million

tonnes of rice , for producing Millet ( which requires much less water as compared

to rice ) , how come you say that only 1.36 million tons of millet can be produced

 !

I would have thought , it should be 5 to 10 times more ! Please recheck ,

recalculate and rewite your reply

 

ChatGPT got back :

 

Apologies for the confusion, and you are right

I made an error in the calculation. Let's re-evaluate the potential millet production when diverting the water required for 3.4 million tons of rice:

1.     Water requirement for producing 3.4 million tons of rice:

·        Assuming 2,500 to 5,000 cubic meters of water per ton of rice (source: UNESCO),

·        Total water required for 3.4 million tons of rice could be between 8.5 to 17 billion cubic meters.

 

2.     Potential millet production with the same amount of water:

·        Assuming 2,500 cubic meters of water per ton of millet (source: ICRISAT),

·        With 17 billion cubic meters of water, the potential millet production would be 6.8 million tons.

·        With 8.5 billion cubic meters of water, the potential millet production would be 3.4 million tons.

Therefore, by diverting the water required for 3.4 million tons of rice to millet production, India could potentially produce 3.4 to 6.8 million tons of millet.

This increased millet production could indeed have a more substantial impact on reducing malnutrition in the country. Millet's nutritional value and its ability to thrive in water-limited conditions make it a promising option for enhancing food security in regions facing water scarcity.

Thank you for pointing out the mistake, and I hope this corrected information clarifies the potential benefit of diverting water to millet production.

Dear Policy Makers

( Petroleum Ministry – Transport Ministry )

 

As far as using FOOD GRAINS ( and also SUGAR CANE ) for producing Ethanol ( for blending with Petrol ) is concerned , considerations are bound to differ from one country to another

In our case , we should use food grains to fight malnutrition – and not for saving petrol

I urge you to reconsider our policy
