Yesterday, Members of Parliament in Lok Sabha discussed the situation of drought and drinking water crisis in many states. During the course of the discussion, some MPs also raised the issue of ground water depletion. Last month, the Bombay High Court passed an order to shift IPL matches scheduled for the month of May out of the state of Maharashtra. The court cited an acute water shortage in some parts of the state for its decision. In light of water shortages and depletion of water resources, this blog post addresses some frequently asked questions on the extraction and use of ground water in the country. Q: What is the status of ground water extraction in the country? A: The rate at which ground water is extracted has seen a gradual increase over time. In 2004, for every 100 units of ground water that was recharged and added to the water table, 58 units were extracted for consumption. This increased to 62 in 2011.[1] Delhi, Haryana, Punjab and Rajasthan, saw the most extraction. For every 100 units of ground water recharged, 137 were extracted. In the recent past, availability of ground water per person has reduced by 15%. In India, the net annual ground water availability is 398 billion cubic metre.[2] Due to the increasing population in the country, the national per capita annual availability of ground water has reduced from 1,816 cubic metre in 2001 to 1,544 cubic metre in 2011. Rainfall accounts for 68% recharge to ground water, and the share of other resources, such as canal seepage, return flow from irrigation, recharge from tanks, ponds and water conservation structures taken together is 32%. Q: Who owns ground water? A: The Easement Act, 1882, provides every landowner with the right to collect and dispose, within his own limits, all water under the land and on the surface.[9] The consequence of this law is that the owner of a piece of land can dig wells and extract water based on availability and his discretion.[10] Additionally, landowners are not legally liable for any damage caused to water resources as a result of over-extraction. The lack of regulation for over-extraction of this resource further worsens the situation and has made private ownership of ground water common in most urban and rural areas. Q: Who uses ground water the most? What are the purposes for which it is used? A: 89% of ground water extracted is used in the irrigation sector, making it the highest category user in the country.[3] This is followed by ground water for domestic use which is 9% of the extracted groundwater. Industrial use of ground water is 2%. 50% of urban water requirements and 85% of rural domestic water requirements are also fulfilled by ground water. 
The main means of irrigation in the country are canals, tanks and wells, including tube-wells. Of all these sources, ground water constitutes the largest share. It provides about 61.6% of water for irrigation, followed by canals with 24.5%. Over the years, there has been a decrease in surface water use and a continuous increase in ground water utilisation for irrigation, as can be seen in the figure alongside. [4] Q: Why does agriculture rely most on ground water? A: At present, India uses almost twice the amount of water to grow crops as compared to China and United States. There are two main reasons for this. First, power subsidies for agriculture has played a major role in the decline of water levels in India. Since power is a main component of the cost of ground water extraction, the availability of cheap/subsidised power in many states has resulted in greater extraction of this resource.[5] Moreover, electricity supply is not metered and a flat tariff is charged depending on the horsepower of the pump. Second, it has been observed that even though Minimum Support Prices (MSPs) are currently announced for 23 crops, the effective price support is for wheat and rice.[6] This creates highly skewed incentive structures in favour of wheat and paddy, which are water intensive crops and depend heavily on ground water for their growth. It has been recommended that the over extraction of ground water should be minimized by regulating the use of electricity for its extraction.[7] Separate electric feeders for pumping ground water for agricultural use could address the issue. Rationed water use in agriculture by fixing quantitative ceilings on per hectare use of both water and electricity has also been suggested.[8] Diversification in cropping pattern through better price support for pulses and oilseeds will help reduce the agricultural dependence on ground water.[6] [1] Water and Related Statistics, April 2015, Central Water Commission, http://www.cwc.gov.in/main/downloads/Water%20&%20Related%20Statistics%202015.pdf.

The Monetary Policy Committee (MPC) has decided to conduct an off-cycle meeting today to discuss the failure to meet the inflation target under Section 45ZN of the Reserve Bank of India Act, 1934. As per the Reserve Bank of India Act (RBI), 1934, MPC is required to meet at least four times each year, to discuss the macroeconomic issues in the country, and take policy decisions to address those. This is the second time MPC has conducted an off-cycle meeting in 2022-23. The meeting is scheduled in light of inflation being consistently high for nine consecutive months.
In this blog, we discuss what the inflation targeting framework is, examine retail and wholesale prices, and the divergence between them.
What is the inflation targeting framework, and what happens if inflation is persistently high?
In 2016, Parliament amended the RBI Act, 1934 to change the monetary policy, and introduce an inflation targeting framework. This framework prioritises price stability to achieve sustainable GDP growth. Price stability allows investors to confidently invest their money for productive activities, without worrying about it losing value. Price stability also maintains the purchasing power of consumers, i.e., the ability to purchase a good (or service) with a given amount of money.
As per the new framework, the central government, in consultation with RBI sets: (i) an inflation target, and (ii) an upper and lower tolerance level for retail inflation. The target has been set at 4%, with an upper tolerance limit of 6% and a lower tolerance limit of 2%. The upper and lower limits indicate that although it is desirable for inflation to be close to 4%, deviation between these limits is acceptable. The target and bands are revised every five years. In March 2021, the existing targets were carried forward.
Retail inflation has been above 6% for the past nine months, and it has been above 4% from October 2019 onwards (See Figure 1).

If inflation is above or below the prescribed limits for three quarters, RBI must submit a report to the central government explaining why prices have been rising (or falling) persistently, what will be done to correct that, and an estimate as to when the target will be achieved.
The MPC uses tools such as interest rates to control the level of inflation in the economy. One such rate is the policy repo rate, which is the rate at which RBI lends money to banks. An increase in the policy repo rate makes borrowing money more costly, and hence is expected to control inflation by reducing the money supply. MPC increased this rate from 4% in April 2022 to 4.4% in May 2022, to 4.9% in June 2022, to 5.4% in August 2022, and to 5.9% in September 2022.
Breaking down the Consumer Price Index and the Wholesale Price Index
Consumer Price Index (CPI) measures the general prices of goods and services such as food, clothing, and fuel over time. Retail inflation is calculated as the change in the CPI over a period of time. Goods and services such as petrol, food products, health, and education are considered for its calculation, which are assigned different weights (See Table 1). Between February 2022 and August 2022, the average annual inflation was 6.9%. The rise in prices of subcomponents of the CPI during this period is indicated in Table 2.

CPI is not the only index that measures inflation in an economy. The Wholesale Price Index (WPI) measures the wholesale prices of goods. A change in wholesale prices reflects wholesale inflation. Table 3 indicates the weights assigned to goods for calculating the WPI. Manufactured goods include metals, chemicals, food products, and textiles.

Primary articles (23%) include food articles, and crude petroleum and natural gas. Fuel and power (12%) include mineral oils, electricity, and coal. WPI has remained above 10% from April 2021 onwards. It reached an all-time high of 17% in May 2022. This was driven by the inflation in metals, kerosene and petroleum coke, fruits and vegetables, and palm oil. |

Why has WPI inflation been consistently above CPI inflation?
Movements in the WPI have an impact on the CPI. For almost a year and half, CPI inflation has remained below WPI inflation. However, as per the design of the indices, it is expected that CPI would remain above WPI, and that any increase in WPI would reflect in the CPI after a time lag. This is because retail prices include taxes (as a percentage of price), while wholesale prices do not. Additionally, some of the goods in WPI act as inputs in the goods considered in CPI. An increase in input prices would lead to higher retail prices after a time lag.
We discuss possible reasons for why CPI has remained below WPI for a year and a half.

Composition of indices
As indicated in Table 2 and 3, the composition of the two indices varies. For instance, prices of manufacture of basic metals, chemicals, and machinery grew at an average rate of 13% between February 2021 and September 2022. They contribute 7% to the WPI. These are input goods for producing final goods and services such as automobiles, which are included in the CPI. The rise in prices of transport vehicles, communication devices, fuel for transport, and housing (CPI components) rose by 6% during this period.
The Ministry of Finance has observed that wholesale prices did not feed into retail prices (from March 2021 onwards) as wholesalers absorbed the rising input costs and did not pass them on to retailers. In August 2022, it noted that as retail prices are rising now, the pass-through may occur.
