Tubewells are fitted with pumps, which require energy such as diesel, electricity or solar.<\/p>\n\n\n\n<p>Diesel pumps power the majority of tubewells in <a href=\"https:\/\/solar.iwmi.org\/wp-content\/uploads\/sites\/43\/2021\/09\/NEPAL-SITUATION-ANALYSIS-REPORT_final-version-3.pdf\">Nepal,<\/a> <a href=\"https:\/\/mnfsr.gov.pk\/SiteImage\/Misc\/files\/ASP%2021-22.pdf\">Pakistan<\/a> and <a href=\"https:\/\/www.adb.org\/sites\/default\/files\/publication\/935026\/solar-irrigation-pumps-bangladesh-2023-2031.pdf\">Bangladesh<\/a> (74-90%), while in <a href=\"https:\/\/mowr.nic.in\/irrigationcensus\/Files\/MI%20Volume-1.pdf\">India<\/a>, electric pumps power around 76% of tubewells.<\/p>\n\n\n\n<p>With diesel pumps, farmers often pay for fuel out of pocket. Electric pumps are cheaper to operate thanks to power subsidies for irrigation, which are widespread across the region. Governments supply electricity for irrigation either free of charge or below market rates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-subsidies-a-double-edged-sword\">Subsidies: a double-edged sword<\/h2>\n\n\n\n<p>Subsidised electricity has <a href=\"https:\/\/academic.oup.com\/chicago-scholarship-online\/book\/30945\/chapter-abstract\/262621674?redirectedFrom=fulltext\">contributed<\/a> to food security by supporting farmer livelihoods, increasing food production and stabilising food prices. However, it has also contributed to <a href=\"https:\/\/www.journals.uchicago.edu\/doi\/10.1086\/735770\">electric utilities\u2019 financial insolvency<\/a>, and, perhaps more alarmingly, to wasteful irrigation and the <a href=\"https:\/\/ieg.worldbankgroup.org\/blog\/addressing-groundwater-depletion-lessons-india-worlds-largest-user-groundwater\">depletion of aquifers<\/a>, with depth to water <a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/full\/10.1029\/2024EF004516\">falling<\/a> by around 1.5 cm per year in north India between 2002 and 2021.<\/p>\n\n\n\n<p>When tubewell owners pay electricity tariffs far below supply costs, governments shoulder the financial losses. A tubewell owner is also less likely to use water or electricity efficiently when they barely cost anything.<\/p>\n\n\n\n<p>Solving these problems, however, is not simply about increasing energy prices. Apart from being politically unpopular, price increases would be challenging to implement as they would require metering electric tubewells, most of which are unmetered. Additionally, getting millions of farmers to accept being metered is no small feat.<\/p>\n\n\n\n<p>More importantly, increasing electricity prices may harm farmers\u2019 livelihoods and increase the price of food production. And because large-scale data on the sale and purchase of groundwater is not usually collected, implementing pricing reforms will be complicated. &nbsp;<\/p>\n\n\n\n<p>Consequently, policymakers are experimenting with alternative approaches.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-water-efficient-technology\">Water-efficient technology<\/h2>\n\n\n\n<p>Among these is to increase the use of <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/agec.70004\">technologies<\/a> that can potentially reduce wasteful irrigation.<\/p>\n\n\n\n<p>One of these is <a href=\"https:\/\/dsrc.irri.org\/our-work\/what-is-dsr\">direct seeded rice (DSR)<\/a>. With this method, farmers plant rice seeds directly in a moistened field instead of the traditional approach of germinating seedlings in a nursery and transplanting them. DSR eliminates the need for the constant field-flooding required by the transplantation process.<\/p>\n\n\n\n<div class=\"wp-block-cd-article-image aligncenter block--article-image block--article-image--article\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--article-image__column\"><div class=\"hide-expand block--article-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2025\/11\/20251121_Bangladesh-wheat-fields-grown-using-groundwater_SoumyaBalasubramanya.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2025\/11\/20251121_Bangladesh-wheat-fields-grown-using-groundwater_SoumyaBalasubramanya-768x574.jpg 768w, https:\/\/dialogue.earth\/content\/uploads\/2025\/11\/20251121_Bangladesh-wheat-fields-grown-using-groundwater_SoumyaBalasubramanya-1024x765.jpg 1024w, https:\/\/dialogue.earth\/content\/uploads\/2025\/11\/20251121_Bangladesh-wheat-fields-grown-using-groundwater_SoumyaBalasubramanya.jpg 2560w\" data-sizes=\"(max-width: 600px) 768px, (max-width: 1024px) 1024px, 2560px\" alt=\"wheat field under a clear blue sky\"\/><\/div><div class=\"block--article-image__content\"><div itemprop=\"caption\" class=\"block--article-image__caption\">Wheat fields in Bangladesh grown using water pumped up from underground (Image: Soumya Balasubramanya)<\/div><\/div><\/div><meta itemprop=\"contentUrl\" content=\"https:\/\/dialogue.earth\/content\/uploads\/2025\/11\/20251121_Bangladesh-wheat-fields-grown-using-groundwater_SoumyaBalasubramanya.jpg\"\/><meta itemprop=\"contentSize\" content=\"2 MB\"\/><meta itemprop=\"height\" content=\"1912\"\/><meta itemprop=\"width\" content=\"2560\"\/><meta itemprop=\"author\"\/><meta itemprop=\"representativeOfPage\" content=\"true\"\/><\/div>\n\n\n\n<p>Another is <a href=\"http:\/\/www.knowledgebank.irri.org\/training\/fact-sheets\/water-management\/saving-water-alternate-wetting-drying-awd\">alternate wetting and drying (AWD)<\/a>, in which farmers only periodically drain and re-flood rice fields. They install a perforated plastic pipe in the rice field to monitor water levels, and only flood the field when water in the pipe falls to about 15 cm below the surface of the soil.<\/p>\n\n\n\n<p>Despite relatively <a href=\"https:\/\/www.tbsnews.net\/agriculture\/awd-water-saving-method-cuts-paddy-irrigation-costs-20-25-1144121\">low costs<\/a> and <a href=\"https:\/\/www.global-agriculture.com\/india-region\/haryana-commits-indias-highest-subsidy-for-direct-seeded-rice\/\">efforts by regional governments<\/a> to increase uptake of these technologies, adoption remains low. Farmers are sometimes <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/agec.70004\">put off<\/a> by unintended effects of these methods. DSR and AWD, for example, both increase weeds in fields, reducing net profits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-rewards-and-risks-of-solar-pumping\">The rewards and risks of solar pumping<\/h2>\n\n\n\n<p>Another approach, increasing in popularity, is powering the pumps with sunlight. In recent years, governments in South Asia have been subsidising solar-pump-and-panel kits.<\/p>\n\n\n\n<p>In India alone, more than 500,000 small solar pumps had been <a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.adi9497\">installed<\/a> as of 2023, from <a href=\"https:\/\/www.epw.in\/journal\/2021\/48\/special-articles\/karnatakas-surya-raitha-experiment.html\">less than 4,000<\/a> in 2012.<\/p>\n\n\n\n<p>Subsidising equipment is attractive for governments because it is one-time, unlike a recurring power subsidy. And farmer demand for solar pumps is high because of the lack of running costs. Empirical assessments from <a href=\"https:\/\/cgspace.cgiar.org\/server\/api\/core\/bitstreams\/d0e7f0dd-0c36-47b1-8477-e965e730c0bb\/content\">Nepal<\/a>, as well as the Indian states of <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0301421519300953\">Rajasthan<\/a> and <a href=\"https:\/\/www.tandfonline.com\/doi\/full\/10.1080\/02508060.2017.1312085#abstract\">Bihar<\/a>, show that solar pumps increase the amount of irrigated areas and food production, because access to affordable water improves; this produces significant improvements in farmer incomes and livelihoods.<\/p>\n\n\n\n<p>However, the assessments also confirm that the costless pumping will almost certainly <a href=\"https:\/\/www.science.org\/doi\/epdf\/10.1126\/science.adi9497\">encourage<\/a> more pumping.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-potential-of-cash-incentives\">The potential of cash incentives<\/h2>\n\n\n\n<p>Another approach involves setting an entitlement of electricity units on tubewells for each well owner, without increasing prices, and offering to purchase unused electricity units at a rebate price. This strategy is being piloted by utilities in several Indian states.<\/p>\n\n\n\n<p>The rebate price is set lower than what it costs the utility to supply energy, and higher than what farmers pay when they use electricity to pump groundwater. This incentivises the tubewell owner to avoid pumping unless it improves yield, because they can earn some money from selling unused electricity units.<\/p>\n\n\n\n<a class=\"wp-block-cd-related-news alignright block--related-news loading\" data-post-id=\"60085701\"><div class=\"block--related-news__image\"><\/div><div class=\"block--related-news__content\"><span class=\"block--related-news__heading\">Recommended<\/span><span class=\"block--related-news__title\"><\/span><\/div><\/a>\n\n\n\n<p>Emerging evidence from pilot studies of such cash incentives in Punjab and Gujarat suggests mixed results in reductions of wasteful use of water and electricity. A 2022 <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1111\/ajae.12340\">paper<\/a> I co-authored shows that in Punjab, when rice farmers were provided with uninterrupted daytime electricity, cash incentives can lead them to reduce power consumption by at least 7.5%, and irrigation hours by up to 30%, without impacting yields. A 2016 <a href=\"https:\/\/qsel.columbia.edu\/assets\/uploads\/blog\/2016\/publications\/india-groundwater.pdf\">study<\/a> from Gujarat, meanwhile, shows no evidence of cash incentives impacting water use.<\/p>\n\n\n\n<p>The pilot programmes also reveal difficulties in setting the entitlements. This is challenging because most tubewells are unmetered, shrouding in mystery the history of usage at individual tubewells. Setting entitlements too low would punish farmers. Too high would defeat the purpose of the approach. &nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-managing-expectations-and-navigating-trade-offs\">Managing expectations and navigating trade-offs<\/h2>\n\n\n\n<p>Ultimately, there is no one-size-fits-all solution. A practical approach may therefore be to acknowledge the trade-offs involved in the various strategies, between rescuing utilities, improving irrigation efficiency, reducing pressure on groundwater and supporting farmer livelihoods. Doing so may help policymakers choose a location-appropriate strategy.<\/p>\n\n\n\n<p>For example, a 2023 paper on an experiment introducing AWD to 2,000 farmers in Bangladesh, <a href=\"https:\/\/oar.icrisat.org\/12555\/1\/American%20Economic%20Journal_Applied%20Economics_15_1_319-350_2023.pdf\">found<\/a> the technology led to conservation of water in areas where farmers paid modest payments for pumping. <a href=\"https:\/\/www.tandfonline.com\/doi\/full\/10.1080\/02508060.2017.1312085\">Deploying<\/a> solar pumps in eastern parts of South Asia, where irrigation is underdeveloped and poverty is deep, has improved farmers\u2019 access to water and thus crop yields.<\/p>\n\n\n\n<p>Activating sensors where present on new solar and electric pumps can improve <a href=\"https:\/\/www.nature.com\/articles\/s41597-025-05899-5\">measurement and monitoring<\/a> of how much groundwater is pumped out. In addition, introducing tailored questions on irrigation in agricultural census and sample questionnaires can generate data on use, including the buying and selling of groundwater.<\/p>\n\n\n\n<p>In South Asia, where farmers continue to be poor, and where climate change is likely to <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.adi1401\">exacerbate<\/a> groundwater depletion, researchers should highlight the effects of potential policy approaches on smallholders in order to nudge policymakers towards contextually appropriate solutions. &nbsp;<\/p>\n\n\n\n<p>Collaborations between policymakers, farmers and researchers can produce actionable knowledge and identify practical solutions. Policymakers can benefit from the lessons that theory and empirical evidence have to offer. Researchers can learn from the challenges that implementers face to better target their endeavours.<\/p>\n\n\n\n<p>Ultimately, however, to manage complex trade-offs and to make discernible progress in managing groundwater resources for livelihoods, centering farmers\u2019 needs is vital. After all, it is through such co-creation that the Green Revolution came about.&nbsp;<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>As groundwater depletes, the region must
