The study identifies factors behind the groundwater depletion in Punjab (India) and examines the economics of groundwater irrigation across farm-size categories, varied groundwater levels and energy policy scenario. The farm-level evidences point out that farmers with smaller land holdings incur 2-3 times groundwater cost than those with larger land holdings. Also, small farmers are affected more adversely due to falling groundwater level. Further, financial expenses in extracting groundwater are borne equally by the society and the farmers. The withdrawal of energy subsidy is expected to reduce net returns, but at a varying rate across different crops. However, crop cultivation would still be profitable and desubsidization will result in 29-82% savings in existing groundwater use in different crops.Keywords

A As part of control and automation Proportional-Integral-Derivative (PID) control schemes have been widely used in most of the control engineering applications including the field of mechanical engineering. A mechanical system’s transfer function is considered in the paper for which a controller is designed using non-traditional optimization technique. The stability and performance of this mechanical system is greatly governed by the controller settings.

Increasing global water shortage emphasizes the need for demand-side water management policies, especially in the agriculture sector, being the largest consumer of freshwater. Such policies are relevant in India, where groundwater depletion may have severe implications at various socio-economic levels. In this study, using mathematical modelling, we assess the feasibility of two alternative irrigation water pricing policies – (i) uniform water pricing policy and (ii) differentiated water pricing policy, wherein farmers growing less water-requiring crops (<4488 m3/ha) get an incentive for saving water, while those growing water-intensive crops pay for it. Using a case study of Punjab, the breadbasket and one of the fastest groundwater-depleting states in India, alternative cropping patterns are also suggested. The findings reveal that the current rate of groundwater withdrawal could not sustain agricultural intensification in the state. Although optimization of resource allocation has the potential to save water by 8%, this alone is unlikely to break the rice–wheat mono-cropping pattern in Punjab. The analysis of two different volumetric irrigation water pricing policies shows that differentiated water pricing would be more effective in halting groundwater depletion in the state. However, adequate investment in irrigation water supply infrastructure, mainly for installing water meters, is required to implement the policyFull Text
