And each time I went to the experts to clarify, they\u2019d explode all my&nbsp;basic assumptions.<\/p>\n<p>So instead of writing that piece, here\u2019s a list of all the (misguided) conventional wisdom I had absorbed set right&nbsp;\u2014&nbsp;or, at least, clarified.<\/p>\n<h3><strong>California hasn\u2019t forced agriculture to cut water use: A myth<\/strong><\/h3>\n<p>Californians just don\u2019t want to be suckers. When Gov. Jerry Brown told the state to cut back water use by 25 percent, he didn\u2019t mention agriculture, and that made people suspicious. It looked to a lot of people like farms were getting a free pass. They (reasonably) thought,&nbsp;<em>I don\u2019t want to be a dupe and scrimp and save if agriculture isn\u2019t doing the same.&nbsp;<\/em><\/p>\n<p>So why didn\u2019t California also demand that&nbsp;ag cut back?<\/p>\n<p>It actually did,&nbsp;said Doug Parker, director of the&nbsp;<a href=\"http:\/\/ciwr.ucanr.edu\/\" target=\"_blank\" rel=\"noopener noreferrer\">University of California Institute of Water Resources<\/a>. Brown just didn\u2019t talk about that when he made&nbsp;<a href=\"http:\/\/hanfordsentinel.com\/news\/in_focus\/california_drought\/state-water-project-growers-get-percent\/article_18eaa03b-36d3-52ce-a15f-5e230a991c84.html\" target=\"_blank\" rel=\"noopener noreferrer\">his big announcement<\/a>&nbsp;(he\u2019s probably kicking himself about that). Growers that rely on the&nbsp;<a href=\"http:\/\/en.wikipedia.org\/wiki\/California_State_Water_Project\" target=\"_blank\" rel=\"noopener noreferrer\">State Water Project<\/a>&nbsp;are taking&nbsp;<a href=\"http:\/\/hanfordsentinel.com\/news\/in_focus\/california_drought\/state-water-project-growers-get-percent\/article_18eaa03b-36d3-52ce-a15f-5e230a991c84.html\" target=\"_blank\" rel=\"noopener noreferrer\">an 80 percent cut from their normal water share<\/a>. Central Valley farmers who draw from the&nbsp;<a href=\"http:\/\/en.wikipedia.org\/wiki\/Central_Valley_Project\" target=\"_blank\" rel=\"noopener noreferrer\">federal system of dams and canals<\/a>&nbsp;have taken a 100 percent cut. Brown may be going back for&nbsp;<a href=\"http:\/\/www.sacbee.com\/news\/state\/california\/water-and-drought\/article17920022.html\" target=\"_blank\" rel=\"noopener noreferrer\">further<\/a>&nbsp;restrictions.<\/p>\n<p>When farmers get these cuts, they cope by pumping groundwater (which is causing problems in some places \u2014 more on this later), or buying water&nbsp;from people with senior water rights. But ultimately, cuts in water deliveries lead to cuts in water use. California farmers took about&nbsp;<a href=\"http:\/\/news.ucdavis.edu\/search\/news_detail.lasso?id=10978\" target=\"_blank\" rel=\"noopener noreferrer\">5&nbsp;percent of their land out of production<\/a>&nbsp;last year, and that number will surely go up this year.<\/p>\n<h3><strong>Agriculture uses 80 percent of California\u2019s water: Not the whole picture<\/strong><\/h3>\n<p>This isn\u2019t exactly wrong, but it\u2019s useful to understand the nuance. Here\u2019s how water is divvied up in California:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/grist.files.wordpress.com\/2015\/04\/screen-shot-2015-04-15-at-10-54-39-am.png?w=569&amp;h=371\" alt=\"Screen Shot 2015-04-15 at 10.54.39 AM\" width=\"569\" height=\"371\"><\/p>\n<p><em>Northern California Water Association<\/em><\/p>\n<p>You do get farmers using 80 percent of water and cities using 20 percent if you don\u2019t count the other pieces of the pie. But those pieces are important, and by no means guaranteed! We are using that water to create habitat and beauty, to allow lots of species to thrive. Leave that out of the equation and&nbsp;<a title=\"A kayak trip down the hardest working river in the world\" href=\"http:\/\/grist.org\/food\/a-kayak-trip-down-the-hardest-working-river-in-the-world\/\" target=\"_blank\" rel=\"noopener noreferrer\">it\u2019s easy to forget about the environment and the human joy that comes with rivers<\/a>. And in dry years like this, the percentage dedicated to the environment isn\u2019t enough for some species:&nbsp;<a href=\"http:\/\/grist.org\/food\/everything-i-thought-i-knew-about-water-in-california-is-wrong\/(which%20is%20causing%20problems%20in%20some%20places%20--%20more%20on%20this%20later)\" target=\"_blank\" rel=\"noopener noreferrer\">Biologists are worried about salmon<\/a>, and the&nbsp;<a href=\"http:\/\/www.mercurynews.com\/drought\/ci_27918392\/california-drought-delta-smelt-survey-tallies-one-fish\" target=\"_blank\" rel=\"noopener noreferrer\">delta smelt are on permanent life support<\/a>.<\/p>\n<h3><strong>Dumb&nbsp;laws prevent the buying and selling of water: Not true any more<\/strong><\/h3>\n<p>This was one of the conclusions of&nbsp;<a title=\"Making almonds the drought\u2019s scapegoat? That\u2019s nuts\" href=\"http:\/\/grist.org\/food\/making-almonds-the-droughts-scapegoat-thats-nuts\/\" target=\"_blank\" rel=\"noopener noreferrer\">my last piece on the drought<\/a>. And that was true \u2026 back in the 1970s. Back then, if you had rights to water, you had to use it or lose it, said Parker. So if you had senior water rights for a patch of rocky desert land, unsuited to growing anything, you still had an incentive to use as much of your water as you could. But that rule changed around 1980. Now, you can take that water and sell it to a city, or a farmer with great soil but little water.<\/p>\n<p>This is confusing \u2014 I\u2019d assumed that farmers were&nbsp;slow to adopt water conservation practices because they had cheap water from senior rights. After all, between 40 and 50 percent of farm irrigation in California is flood&nbsp;irrigation: You generally use little sections&nbsp;of curved pipe to siphon water out of a ditch, and&nbsp;flood the furrows between the rows of plants.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/grist.files.wordpress.com\/2015\/04\/floodirrigation.jpg?w=460&amp;h=371\" alt=\"flood irrigation in Arizona\" width=\"460\" height=\"371\">&nbsp;<\/p>\n<p><em>Flood irrigation in Arizona.<\/em><\/p>\n<p>This seems wasteful, and indeed it requires a lot more water than drip irrigation.&nbsp;I thought that a market for water would drive otherwise wasteful farmers to adopt better techniques \u2014 but that reasoning relied on another incorrect assumption.<\/p>\n<h3><strong>Farmers are wasting a lot of water: A myth<\/strong><\/h3>\n<p>Um, not really, said Ellen Hanak, director of the&nbsp;Water Policy Center at the Public Policy Institute of California.<\/p>\n<p>\u201cBut let\u2019s say I\u2019m a farmer down in the Imperial Valley,\u201d I said. \u201cI\u2019ve got senior water rights from the Colorado River, and I\u2019ve always used flood irrigation. Now that I can sell my water on the market, shouldn\u2019t I be installing drip irrigation? I\u2019d use a lot less water to grow my lettuce, and I could sell the rest. I make money, there\u2019s more water to go around, everyone wins.\u201d<\/p>\n<p>\u201cYou can\u2019t do that,\u201d Hanak said. \u201cNot allowed.\u201d<\/p>\n<p>\u201cWhy not?\u201d<\/p>\n<p>Well, basically because flood irrigation is not nearly as wasteful as it looks. Yes, it takes a lot&nbsp;more water than other forms of irrigation, but all that extra water&nbsp;goes somewhere: It seeps into the ground and restores aquifers, or it flows out of the field and back into the river. So, if I sell all my water, it suddenly deprives my neighbors of my backwash, which they\u2019ve come to rely on. Therefore, the law doesn\u2019t allow me to sell that portion that historically passed through my field and then continued on&nbsp;downstream, or underground.<\/p>\n<p>Aha! I thought. So&nbsp;<em>this<\/em>&nbsp;is the dumb law causing the market to fail! Get rid of this obstacle, and farmers will adopt more efficient practices, leaving us with plenty of water, right?<\/p>\n<p>Wrong, Hanak said. That\u2019s another misconception.<\/p>\n<h3><strong>Farm conservation measures can free up plenty of water: One last myth<\/strong><\/h3>\n<p>Switching from flood irrigation to a more efficient system like drip does improve water quality. And you lose less water to evaporation \u2014 but just a little bit. You can see how this works in this infographic from the Pacific Institute (don\u2019t pay too much attention to the specific numbers, they are just rough placeholders).<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/grist.files.wordpress.com\/2015\/04\/screen-shot-2015-04-16-at-1-56-53-pm.png?w=660&amp;h=502\" alt=\"Screen Shot 2015-04-16 at 1.56.53 PM\" width=\"560\" height=\"402\"><\/p>\n<p>The thing to pay attention to here is that the \u201cmore efficient water use\u201d scenario, while it keeps mud and salts out of the river,&nbsp;doesn\u2019t save much more water in the end.<\/p>\n<p>\u201cIt\u2019s a very small percentage lost to evaporation,\u201d Hanak said. And in the real world, farmers actually end up using more water when they switch to efficient irrigation, she said. That\u2019s because upgrading irrigation boosts yields:&nbsp;Tomatoes have been setting&nbsp;<a href=\"http:\/\/westernfarmpress.com\/vegetables\/record-2014-california-processing-tomato-industry?page=1\" target=\"_blank\" rel=\"noopener noreferrer\">yield per acre records<\/a>&nbsp;every year, because farmers have come up with&nbsp;<a href=\"http:\/\/www.agalert.com\/story\/?id=5108\" target=\"_blank\" rel=\"noopener noreferrer\">better techniques based on drip irrigation<\/a>. You can see the same thing going on with onions, bell peppers, and cotton. With flood irrigation, water&nbsp;flows<em>through<\/em>&nbsp;farms. With drip irrigation farmers can capture more of that water and grow more food.<\/p>\n<p>The end result: Irrigation upgrades increase farm productivity and profits, but also tend to increase the farm\u2019s net water use. \u201cIrrigation efficiency doesn\u2019t save water for the system as a whole,\u201d Hanak said \u2014 blowing my mind.<\/p>\n<h3><strong>OK, now I know nothing.&nbsp;What is water even for?<\/strong><\/h3>\n<p>Assumptions are useful things \u2014 they provide a foundation for understanding the world. The more I read and talked to experts, the less of that foundation I had left, and I found myself asking the most basic question: What is water for?<\/p>\n<p>Well, it\u2019s for drinking. That\u2019s pretty important.<\/p>\n<p>It\u2019s for growing food \u2014 at least a bare minimum to feed ourselves.<\/p>\n<p>After that, keeping fish alive and ecosystems healthy is a priority \u2014 at least for me.<\/p>\n<p>But even in this historic drought, California has plenty of water left over after those uses.&nbsp;So then we&nbsp;move up the hierarchy of needs to things like lawns and golf courses, and farming as a business (beyond the subsistence level).&nbsp;Hey, we have some of the best growing conditions in the world; maybe we should use the rest of this water to stimulate our economy and&nbsp;export food like almonds.<\/p>\n<p>That\u2019s basically&nbsp;the way that water is divided up at this point. As climate change reduces the water stored in the snowpack, and as populations grow, there will be less water to go around. The system is already under enormous pressure \u2014 there\u2019s not going to be a solution that will make everyone happy.<\/p>\n<p>The least societally important, and least profitable use of water, I suspect, will be farming. Cities will expand, and farms will shrink. We already see that shift happening. Since 2000, farm water use has declined. A lot&nbsp;of that decline comes from farmers taking marginal land out of production, Hanak told me. At the same time, farm income is up: Farmers can afford to give up land because they are planting higher-value crops (like almonds) on the rest of their acreage.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/grist.files.wordpress.com\/2015\/04\/screen-shot-2015-04-16-at-4-10-08-pm.png?w=560&amp;h=422\" alt=\"Screen Shot 2015-04-16 at 4.10.08 PM\" width=\"560\" height=\"422\"><\/p>\n<p>&nbsp;<em><a title=\"image credit\" href=\"http:\/\/www.ppic.org\/content\/pubs\/report\/R_415WFFR.pdf\">PPIC<\/a><\/em><\/p>\n<h3><strong>What then do we do?<\/strong><\/h3>\n<p>Most places in California have plenty&nbsp;of water to keep humans alive.

Some people are beginning to suffer from this classic example of the tragedy of the commons. And it\u2019s always the poor who suffer most.<\/p>\n<p>My first reaction is to look for forceful solutions: Perhaps local governments could stop giving permits to drill wells in sensitive areas.

This is ridiculously late \u2014 think of all the expense&nbsp;and strife we could have saved if we had started managing groundwater 20 years ago. But we seem capable of making hard&nbsp;decisions only when we have no other choice&nbsp;\u2014 the challenge is to make thoughtful decisions, rather than panicked ones that we\u2019ll regret.<\/p>\n<p>The legislature could have imposed rules from above that would be in place now, but lawmakers wanted to allow the people to craft rules that were contextually appropriate. That seems wise to me.&nbsp;It doesn\u2019t make sense to implement the law overnight, Hanak told me,&nbsp;but it would be in the best interest of&nbsp;many farm communities to make rules&nbsp;sooner rather than later \u2014 so they don\u2019t have to wait until 2020.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/grist.files.wordpress.com\/2015\/04\/screen-shot-2015-04-17-at-10-22-21-am.png?w=560&amp;h=405\" alt=\"Screen Shot 2015-04-17 at 10.22.21 AM\" width=\"560\" height=\"405\">&nbsp;<\/p>\n<p><em><a title=\"image credit\" href=\"http:\/\/www.ppic.org\/content\/pubs\/report\/R_415MDR.pdf\">PPIC<\/a><\/em><\/p>\n<p>Meanwhile, we should still be pushing&nbsp;water-conservation practices.

Instead of trying to solve problems with&nbsp;<a href=\"http:\/\/smile.amazon.com\/Seeing-like-State-Certain-Condition\/dp\/0300078153?sa-no-redirect=1\" target=\"_blank\" rel=\"noopener noreferrer\">centralized, top-down control<\/a>, we need rules informed by local knowledge and crafted by local water users. Instead of focusing only on big technological solutions, like desalinization plants and dams, we need to look for small-scale and biological solutions,&nbsp;she said. The \u201conly\u201d there is key: The big engineering projects could really help in the crunch times, but they\u2019re not going to make this problem go away.<\/p>\n<p>Humans faced with a crisis want to find&nbsp;a villain, pick a fight, and exercise quick, top-down action to bring the accused&nbsp;to justice. This kind of thinking may make sense&nbsp;in a small tribe, but it\u2019s all wrong for a complex societal problem like California\u2019s drought. It\u2019s especially hard to avoid this reductive thinking when conventional wisdom is peppered with misconceptions.
