An Irrigation Method For Agriculture

Water scarcity is increasing worldwide and dramatically affecting first world nations such as Spain, Australia, and the United States. All nations are now starting to recognize that the world's water is a finite resource, and that resource is being drastically altered in both availability and quality by development, climate change and population growth. In the United States, the Colorado River is experiencing rapid declines in volume. Recent studies and data suggest that the changes in frequency, intensity, and timing of the availability of water will have substantial impact on the way we live our lives in the 21st century and beyond. As Letmathe Brakeck said, “I am confident that, under present

After intense search we were able to find different types of irrigation systems that represent different forms of irrigation which are also the most commonly used in their category and generally here in the central valley. There are three categories that form the irrigation system: flood, sprinkler, and drip. Flood irrigation providing us with furrow irrigation, sprinkler irrigation having the center pivot irrigation, and drip irrigation having its own beneficial water conservation uses, each which waters our crops but not all in the most effective way possible. Furrow irrigation for example tends to flood the crops with water in order to water them, which is not good for the crops as they will be taking in too much water and drowning. When farmers use furrow irrigation they use as much water at once in

The State of Colorado has suffered from a water shortage in recent years; a difficult situation which is easily visible when viewing the quickly shortening length of the Colorado River. Lake Mead, for example, is roughly 130 feet lower than it once was, marked by the stained rock which towers above the current water level. “The river has become a perfect symbol of what happens when we ask too much of a limited resource: it disappears. In fact, the Colorado no longer regularly reaches the sea” (Zielinski, 2010). Legislation was implemented early on to address this issue, though the results were (perhaps not surprisingly) rather unanticipated, regarding

One of the largest geographic physical structures in the United States is the Colorado River. Human activity and its interaction with this great river have an interesting history. The resources provided by the river have been used by humans, and caused conflict for human populations as well. One of these conflicts is water distribution, and the effects drought conditions have played in this distribution throughout the southwestern region. Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river. It provides water for over 20 million people, irrigation for 2 million acres of land, four thousand megawatts of hydroelectric energy, and over twenty million annual visitors for

Yet, humans have limited control on natural events, so this only reinforces the importance of managing water wisely. Recently California’s government has begun to focus more on sustaining and restoring the water supply. Dale Kasler (2016) articulates in his article some of the steps they have decided to make to solve this serious issue. The government has made the following investments: “$415 million for watershed restoration and other environmental aid for Lake Tahoe; up to $335 million for two proposed reservoirs in California, including the Sites reservoir north of Sacramento; $880 million for flood-control projects on the American and Sacramento rivers in Sacramento; and $780 million for flood-control projects in West Sacramento” (para. 10). This could be the first step to restoring the water to California. But these

For this paper water structures and infrastructures were selected as focus points because the longer we wait to fix issues with them, the more expensive it will get, in other words, we are in a race against time. Studying the past it is easy to see how water availability made population explode in an area such as Southern California, where savvy marketing and great politics made it happen. Particularly, for Los Angeles and for the purposes of public narrative, Marc Reisner’s Cadillac Desert does a great job at understanding and identifying the politics and key figures in getting water to Los Angeles. Great hydrologic structures were created using both manpower and water politics. It is important to state that there are connections between water, politics, environment, and geography when analyzing what the biggest problems involving water structures and infrastructures (Reisner.) We must think of water as both a socio-political issue and a natural resource, whose fate is molded by the understanding of its connectivity to itself, man-made structures, geography, environment, and society. The classes taken in this program have taught us ideals that in order to become a great water resource manager, one must master the political and scientific knowledge to make decisions that are prosperous for society and the environment. Furthermore, one must know the United States’ hydrological history in order to gain manipulation upon the system that makes it both thrive and deteriorate.

Abraham Lustgarten has written a very informative article that is published by Pro Publica and titled “How the West Overcounts Its Water Supplies.” In great detail, he analyzes the drought situation in Arizona and California to draw attention the underlying cause: the miscounting of available water. There is miscounting because officials are refusing to legally accept that the major water resource of the West—the Colorado River—is interconnected with underground water resources. All in all, Lustgarten writes a convincing article that effectively addresses the need for officials to recognize the interconnection of ground and surface water so that water shortage in the West can be better managed; he does this through his ability to gain the

Arizonans see California’s drought and water restrictions plastered all over the television and newspapers. Many Arizonans remain concerned about the well-being of Californians, while some may mistakenly think that it is not Arizona’s problem. I was one of those people, and while investigated the idea, discover how Arizona is in a bad situation because of it. What I, along with others, did not understand is the years of planning, legislation, and engineering that took place to get water to Arizona and the rest of the Southwest. The Southwest is an arid environment that relies on one river, the Colorado River, to deliver water to seven different

On a bright and clear summer day, the birds were chirping, the sun was boring down onto your back. You skipped through the dry fields of grass, the plants withered at your feet. Then you saw it. Was that… water? You set your eyes upon the goal: the stunning oasis of freshwater and leafy green trees only a few steps before you. It was true! You drank the water hurriedly, taking huge gulps as the cold liquid ran down your throat. You paused for a moment, thinking about the border, and the people across it starving for water like you once had. Should you send some over to them? Oh, but the cost! Setting up pipes would be so expensive! The water levels were already lowering rapidly across your side of the border, so maybe you should just salvage

“Climate change” and its impact on basic water supply is at their foreground. It is an unfortunate reality that the terms of the Colorado Compact, the document dividing the Colorado’s waters, is an unworkable document. Based on allotments formulated in an “especially wet year,” the average volume now flowing does not meet the amounts specified in the agreement. Under the terms of the document, California receives the largest share, but with Southern California’s exploding population, this will be increasingly inadequate. Absent changes in both urban and agricultural use patterns, the deficit will only grow and further stress the state’s political and economic systems. Man’s mastery will thus prove illusory and short-lived and the original problems of water supply will return in highly magnified

For millions of years the Colorado River flooded the West with rich sediments, carving out the Grand Canyon, and shaping the Rocky Mountains. Today, agricultural, energy, and population demands have dwindled the once robust flow of water and its tributaries into streams that run dry, lakes that recede, and a Colorado River that hasn’t flowed into the Sea of Cortez, Mexico, since 1998.

(Hasan and Özay 2002, 73-74). As Albiac (2008) reports, development of pipe network distribution and drip irrigation methods in other countries led the farmers to have remarkable irrigation efficiency in drought (143). Such technologies have already been used in China, but they are not widely spread in China’s agriculture. One investigation in China on rice paddy irrigation systems development was performed and it revealed that using the fry-foot paddy irrigation (when no water flooded the field) instead of flooding irrigation (when the rice field is completely flooded) significantly (40-60%) reduces water consumption (Xiaoping, Qiangsheng and Bin 2004, 351). Furthermore, drip irrigation method was applied in arid Northern China and it raised the water usage efficiency (Du et al 2007). However, introduction of new irrigation technologies faced some difficulties in China. As Hodstedt (2010) noticed in his article, the water saved by these technologies such as drip irrigation systems was simply spent on more food production and, therefore, did not reduce the water shortage. Also, as he reported, this caused two other environmental problems. Firstly, the water, which was the supply for underground water and aquifers as it was lost by deep percolation and leakage, became unavailable after the water-saving technologies were introduced and this strengthened the aquifers depleting along with its overpumping. Secondly, after

When referring to Arizona’s water Kris Mayes, chairwoman of the state’s utility regulatory panel once said, “How do you say just how valuable water is in an arid state like Arizona?” she said. “It’s like the credit-card commercial-it’s priceless” (McKinnon). She was right, because in a dry state like Arizona, water is pretty important. To say water is ‘pretty important’ for the world is an understatement. We use water to function. And when we think of water we think of saving it. Keep the faucets from dripping or turn off the water while brushing your teeth. There are numerous tips for water conservation, but people don’t often think of the damage that is already done. Damages like ‘dead zones’. Dead zones in the ocean have been around for

In today’s society, the idea of a limited resource is not a foreign concept. Most people understand that eventually humans will use up many of these resources, such as fossil fuels, and they will cease to exist. However, very rarely does a conversation about limited resources get started over the water. While water itself is not a limited resource, clean drinkable water is becoming scarcer as people continue to use excess water. The documentary “Last Call at the Oasis” highlights how precious water is to survival and just how much miss use of water occurs in the United States alone. Even though the United States has gone down the wrong path with its water consumption methods, it may not be too late to recover. With the proper systems and education in place, the chances of delaying a water crisis increase exponentially.

Increasing threats of freshwater shortage, reduction in arable land, and more frequent and severe droughts due to climate change has stimulated research into water-saving irrigation strategies aiming at producing more ‘crop per drop’ (Morison et al., 2008). The trend in recent years has been towards conversion of surface irrigation to drip irrigation to improve water use efficiency, plant quality and, crop yield. Drip irrigation systems have increasingly been used to supply irrigation water, fertilizers, and pesticides to a wide range of vegetables, field crops, and fruit trees due to their ability to enable highly localized application of water and nutrients to crops (Kandelous et al., 2011; Selim et al., 2013). Drip systems can achieve
