Overirrigation of rice crops from groundwater negatively impacts water productivity, energy use and the environment in Pakistan. Therefore, four decades (1981–2020) of data on rice crop area and production were assessed for water productivity, and alternative options for irrigation application and energy use were explored. The results show a maximum average yield of 2.42 t ha ¹ and water productivity of 0.16 kg m 3 (6211 L kg ¹) for the last decade (2011–2020), with an average decadal yield increase of 14%. The last year's rice crop during 2020 consumed 14.43 million acre-feet (MAF) of groundwater, assuming a minimum irrigation application of 1500 mm per season. The maximum equivalent energy required for pumping is approximately 386 MW for electrical and 4966 MW for diesel-driven tube wells. Diesel combustion for pumping caused 1.26 million t (467 kg ha ¹) of CO2 emissions per season. The capital cost for converting all installed capacities of electrical (2311 MW, PKR 481 billion) and diesel (16 517 MW, PKR 1909 billion) tube wells to solar energy can be recovered in less than 4 years. Improved governance and optimized site-specific solar system designs can avoid undergoing groundwater. Improving water productivity and using solar energy for irrigation indicates the prospects of improved sustainability of rice crops in Pakistan.

In Pakistan's arid agricultural landscape, this 4-year (2020–2023) study on silty loam soil examined the relationships between sowing methods, irrigation practices, rice yield and water productivity. Using a randomized split block design, no tillage (NT) with alternate wetting and drying (AWD) and a furrow-irrigated narrow bed (NB) emerged as being consistently competitive, showing potential for sustainable rice cultivation. Key findings indicate that AWD significantly enhances water productivity (11–35%) and increases yield (2–10%) compared to conventional practices. Drip-irrigated wide beds (WBs) conserve substantial amounts of water (73%) but may compromise rice yield (4–47%). This study provides valuable insights into the dynamic outcomes and distinct performance trends of different rice varieties. The results suggest a potential maximum yield increase of 2–22% through optimized practices, and replacing rice may increase yield by 25–231%. Conversely, the selection of improper irrigation schedules and sowing methods for the given soil and crop conditions may lead to a yield reduction of up to 47% in high-yielding rice varieties. These findings may help to establish a foundation for further research investigating informed decision making for sowing and irrigation methods. The potential scalability of the identified technologies and further in-depth simulation strategies across diverse agroecological zones in Pakistan holds promise for widespread adoption, enhancing the sustainability of rice farming in the region.
