The paper examines the current status of groundwater, discusses various policy interplays and trade offs and identifies some issues for the effectiveness of groundwater policy. Water policy is influenced by various related policies, such as agricultural policy, land-use policy, energy policy, food policy, price policy, environment policy, credit policy, subsidy policy, etc and its effective implementation on the ground requires the participation of local institutions, like PRIs, farmers’ organization, users’ groups and civil society organization, apart from the government departments and agencies. Therefore, interfaces, interplays and interlinks of these policies, institutions, and organizations and groups are crucial for better policy formulation. Region-specific policy risks and tradeoffs and tradeoff among the major policy goals—efficiency, sustainability and equity—are also required to be assessed.

Rainfall analysis is essential for agricultural crop planning and water resources management, especially under water scarcity conditions. The 36 years (1977–2013) of rainfall data for Kharagpur were analyzed for characterization of different seasonal events. The Weibull's formula predicted the probability of mean onset on 23rd standard meteorological weeks (SMW) (3rd–9th June) and withdrawal on 43rd SMW (21st–27th October). There was 80–83% probability of a wet week [P(W)] occurring within 25th–35th SMW. The first order Markov chain process shows the conditional probability of one wet week preceded by another wet week [P(W/W)] varied between 0 and 86%; whereas, dry week preceded by another dry week [P(D/D)] varied in the range of 70 to 100%. The stochastic analysis of successive wet or dry weeks formulates the adaptation strategies to avoid the possible effect of wet or dry spell during cropping seasons. The wet spell analysis suggests rainwater harvesting to control soil erosion and maximization of water use efficiency. The probability of getting consecutive wet [P(W/W)] and dry days [P(D/D)] were varied in the range of 40%–70% and 50%–90%, respectively. The probability of getting different magnitude of rainfall (10 to 40 mm) during the monsoon weeks (25th–39th week) were found to be more than 50% probability level, which suggest for harvesting of excess runoff water for future supplemental irrigation.

The water markets as an institution for water demand and supply management has been extensively documented both theoretically and empirically. The application of successful water market models of developed economies in developing economies has also gained much attention of the researchers and policy makers globally. However, the studies in different regions have stated a number of arguments both in favour and against the water markets as an economic instrument for water use efficiency and equity, particularly in the irrigation sector. The present study conducts a systematic review and meta-analysis for identifying different ways in which the water markets impact irrigation water-use in different regions and analyse the various factors of water markets that impact irrigation water-use efficiency and equity. The results show that all the studies that confirm the trade-off between water-use efficiency and equity are based on markets with inter-sectoral trade, specifically formal markets. Only about 27% of the reviewed studies found that both the objectives of equity and efficiency can be achieved simultaneously with water trading. The impact of water markets on efficiency depends on five factors viz. soft infrastructure/institutional governance, hard infrastructure, physical water scarcity, reliability/Trust in the water market system, and social acceptance. The difference in the very nature of the buyers and sellers in the formal and informal markets largely explains the difference in the functioning of the respective markets. Thus, this study highlights the range of factors behind the heterogeneity in the results of the reviewed studies on the given theme that can support the policy makers in framing the customized water trading policies.

The unregulated use of groundwater for irrigation has led to declining water tables since the extraction rate is more than its recharge. As informal groundwater trading for irrigation has been prevalent in Western Uttar Pradesh, India, for a long time, there is a potential of introducing an organised groundwater irrigation market. Creating a hypothetical organized groundwater market, by following the contingent valuation approach, the present study evaluates the farmers’ willingness to pay (WTP) for groundwater irrigation and the factors determining the same. By collecting primary data from 300 farm households through an interview schedule, the study follows an iterative bidding method for eliciting the farmers’ WTP for the direct use-value of groundwater. The Heckman two-step model is used to estimate the average WTP and its determinants in order to mitigate the impact of sample selectivity bias. The results show that most of the farmers (86%) are willing to contribute to irrigation water reforms in the form of organised water market. The estimated value of WTP for groundwater irrigation is found to be INR 39.30 per hour in the case of 7.5 horsepower tube-well. Moreover, factors like the administrative block, education, social group, land size, primary crop, perception on water scarcity, and perception on water meters significantly impact the maximum WTP for groundwater irrigation. Interestingly, the WTP of tube-well owners who are not involved in groundwater trading is found to be 23% lower than that of groundwater buyers who are primarily marginal and small land holders, implying that even resource-poor farmers are willing to pay higher prices, if reliable groundwater irrigation is ensured.
