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.

In November 2017, the 15th Finance Commission (Chair: Mr N. K. Singh) was constituted to give recommendations on the transfer of resources from the centre to states for the five year period between 2020-25. In recent times, there has been some discussion around the role and mandate of the Commission. In this context, we explain the role of the Finance Commission.
What is the Finance Commission?
The Finance Commission is a constitutional body formed every five years to give suggestions on centre-state financial relations. Each Finance Commission is required to make recommendations on: (i) sharing of central taxes with states, (ii) distribution of central grants to states, (iii) measures to improve the finances of states to supplement the resources of panchayats and municipalities, and (iv) any other matter referred to it.
Composition of transfers: The central taxes devolved to states are untied funds, and states can spend them according to their discretion. Over the years, tax devolved to states has constituted over 80% of the total central transfers to states (Figure 1). The centre also provides grants to states and local bodies which must be used for specified purposes. These grants have ranged between 12% to 19% of the total transfers.
Over the years the core mandate of the Commission has remained unchanged, though it has been given the additional responsibility of examining various issues. For instance, the 12th Finance Commission evaluated the fiscal position of states and offered relief to those that enacted their Fiscal Responsibility and Budget Management laws. The 13th and the 14th Finance Commissionassessed the impact of GST on the economy. The 13th Finance Commission also incentivised states to increase forest cover by providing additional grants.
15th Finance Commission: The 15th Finance Commission constituted in November 2017 will recommend central transfers to states. It has also been mandated to: (i) review the impact of the 14th Finance Commission recommendations on the fiscal position of the centre; (ii) review the debt level of the centre and states, and recommend a roadmap; (iii) study the impact of GST on the economy; and (iv) recommend performance-based incentives for states based on their efforts to control population, promote ease of doing business, and control expenditure on populist measures, among others.
Why is there a need for a Finance Commission?
The Indian federal system allows for the division of power and responsibilities between the centre and states. Correspondingly, the taxation powers are also broadly divided between the centre and states (Table 1). State legislatures may devolve some of their taxation powers to local bodies.
The centre collects majority of the tax revenue as it enjoys scale economies in the collection of certain taxes. States have the responsibility of delivering public goods in their areas due to their proximity to local issues and needs.
Sometimes, this leads to states incurring expenditures higher than the revenue generated by them. Further, due to vast regional disparities some states are unable to raise adequate resources as compared to others. To address these imbalances, the Finance Commission recommends the extent of central funds to be shared with states. Prior to 2000, only revenue income tax and union excise duty on certain goods was shared by the centre with states. A Constitution amendment in 2000 allowed for all central taxes to be shared with states.
Several other federal countries, such as Pakistan, Malaysia, and Australia have similar bodies which recommend the manner in which central funds will be shared with states.
Tax devolution to states
The 14th Finance Commission considerably increased the devolution of taxes from the centre to states from 32% to 42%. The Commission had recommended that tax devolution should be the primary source of transfer of funds to states. This would increase the flow of unconditional transfers and give states more flexibility in their spending.
The share in central taxes is distributed among states based on a formula. Previous Finance Commissions have considered various factors to determine the criteria such as the population and income needs of states, their area and infrastructure, etc. Further, the weightage assigned to each criterion has varied with each Finance Commission.
The criteria used by the 11th to 14thFinance Commissions are given in Table 2, along with the weight assigned to them. State level details of the criteria used by the 14th Finance Commission are given in Table 3.
Grants-in-Aid
Besides the taxes devolved to states, another source of transfers from the centre to states is grants-in-aid. As per the recommendations of the 14th Finance Commission, grants-in-aid constitute 12% of the central transfers to states. The 14th Finance Commission had recommended grants to states for three purposes: (i) disaster relief, (ii) local bodies, and (iii) revenue deficit.
