A potential solution for farmers would be to switch to a subsurface drip irrigation system that could permanently cut farmers' water use by 25 to 50 percent. This would alleviate some of the need for conservation and free up more state water reserves for urban use during time of regional drought (U.S. Water News Online).

Surface Irrigation - Basins or trenches with water flowing - due to gravity - in between rows of crops. [17]

The Central Valley Project was a tremendous government project to irrigate the Central Valley, a 450 mile stretch of fertile land that has become very important to agriculture. This valley could not have been able to grow the 230 different types of produce it does today without the Central Valley Project. The government decided to construct a system to irrigate the valley. The author writes that the Central Valley was very dry and considered a desert in 1933. So, the government began a series of construction projects to build aqueducts, canals, and pump plants. The text states that the government directed water from the Colorado River to the valley. Due to this, the Central Valley can cultivate 230 kinds of crops as the center of American

As we all understand, the Earth has many landmarks and it is these physical features that create an abundant and organized system within which we thrive. One of the most abundant natural resources on the planet is water and the importance of this element is as crucial as any other. For the fortunate few who get to utilize it, this amazing reserve provides us with our necessity for daily consumption as well as our ability to grow just about anything we please. Common irrigation practices are essential for gathering water into a contained area to grow crops that would not typically survive in areas without heavy rainfall. As a matter of fact, “irrigation is an ancient practice that originated along the Tigris and Euphrates Rivers in what is now Iraq” and is now the result of an estimated 40 percent of all crops grown around the world (Water Encyclopedia). This tactic has provided many different cultures with numerous varieties of crops as well as growth in crop yield which in turn dramatically advances human civilization. As we develop into a more progressive society, the tools and systems used to grow our crops also become more intelligent as well as sustainable

This essay is a review of the article “Growing More Food with Less Water”, written by Sandra Postel. According the article, our global freshwater sources, including underground aquifers and rivers are stressed beyond their ability to provide freshwater. Agriculture redesign is necessary with the two primary goals being to cut water demands of mainstream agriculture and bring low cost irrigation to poor farmers. Typical irrigation, crop furrow flooding is a main cause of wasted and polluted water. This article discusses alternatives to typical irrigation. These alternatives have been tested onsite by farers and surveyed.

Living on a farm for the first half of my life, I know that my dad and many of our neighbors’ schedules revolved around the rain. Aquaponic and hydroponic methods of farming both provide dramatic reduction in water usage. One system designed by Nate Storey claims to be able to reduce water usage substantially (2014). He says that a similar sized back yard garden will use twenty times the water as hydroponic/aquaponics system. Other systems have seen similar reduction in water usage, because unlike traditional farming with irrigation, aquaponics and hydroponics is a closed system that recirculates water multiple times so that most water loss is through evaporation and the plants using it for osmosis. In traditional farming, water is lost to runoff or evaporates before the crops have a chance to use it. Moreover, aquaponics was originally mentioned as a way to reduce fish imports and allow people of inland populations to have locally raised fish and produce in the Virgin Islands (Rakocy 2000). With the need to provide food, particularly meat, aquaponically raised fish provide an alternative to shipping fish inland from the coasts or international

Is there at least something good about Yuma ? The soil, our soil is the best. Living out in the desert is crucial when it comes to summer but our irrigation system helps out with that. Without that soil we probably wouldn’t be #1 for growing the best lettuce. Not just lettuce that is the best we grow, all sorts of other vegetables and fruits. Our irrigation system is also good here. We may use up a lot of water but that’s what gets us to making our produce, good and ripe for the seasons.

As Australia has a lot of land used for agricultural purposes, we are one of the greatest exporters in the world. This means a lot of the world depends on us for food but when we only have 472mm of water a year, the lowest of all the continents ( except Antartica ) we can find it hard to irrigate our crops at time. With 80% of Australians de-hydrating everyday, some because they don’t care about drinking water but many others as they don’t have the fresh water to drink, if we cannot supply enough water to drink wear are we meant to get the water to irrigate plants? Water scarcity has had a dramatic effect on our ability to grow crops, making it hard to grow crops for not only our country to eat but all the other countries we export food

California is the leading state in agricultural production; however, the state has taken a blow from this four-year drought. Farmers have been forced to re-evaluate their irrigation systems and make necessary changes to conserve water. In order to judge the agricultural water use efficiency, scientists are using a ratio of evapotranspiration of the crop grown to the water applied to the crop. Evapotranspiration is the total evaporation and plant transpiration from land surface to the atmosphere (Marin et al. 2015). Through various

Irrigation is significant to Yuma County because, it has assisted agricultural growth over the years. Financially, the county of Yuma is in the top economically successful counties in the world as the crop sales are in the .1% every year. Before Yuma was successful they first had to overcome many challenges in the land, this changed Yuma geographically and caused for new technology needed that is now used around the United States in the present day. This advancement called for more jobs for thousands and slowly gained population in Yuma. The effects from irrigation are still benefiting Yuma and the people of Yuma today.

There were many ways Yuma Arizona was changed by irrigation, without irrigation we wouldn't be able to grow crops, and sustain human life on earth. Back then Yuma was a small town, and was known as the wild west, but the era started ending when the U.S Reclamation service allowed Yuma to work on an irrigation project which was called the Yuma Project. The plan was to irrigate land throughout the towns of Yuma County,Somerton, and California. The water would come from the All American canal which then takes it to the Yuma main canal, then delivers it to the colorado river which then flows to different cities ,and irrigates land. Soon the project started changing Yuma in several ways with the new irrigation system Yuma started developing. One

(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

We usually associate water shortages with a lack of drinking water, but global water scarcity has a critical impact on food security. Agriculture consumes more water than any other source. Climate change is altering patterns of weather around the world, causing shortages and droughts in some areas and floods in others. Water is key to food security. Crops and livestock need water to grow. Agriculture requires large quantities of water for irrigation and various production processes. Water scarcity may limit food production and supply, putting pressure on food prices and increasing countries’ dependence on food imports

Agriculture in the United States has changed dramatically over the centuries. Since the 1960’s large commercial farms have been leading in sales. As a direct result of their success we, as a society, have access to affordable food. However, the success of large farms has lead to many negative impacts such as increased usage of resources and decreased diversity in crop fields. This begs the question, what can be done to reduce the negative impacts of large farms. One solution growing in popularity is sustainable agriculture. The idea of sustainable agriculture is to create farms that need little to no outside help from irrigation, pesticides, or fertilizers. Sustainability can be achieved in many way through

Agriculture is one of the major sector becoming vulnerable to climate-change. Increased incidences of abiotic and biotic stresses are likely to cause serious negative impact on crop production. Abiotic stress is defined as the negative impact of non-living factors on the living organisms in a specific environment. The non-living variable must influence the environment beyond its normal range of variation to adversely affect the performance or individual organism in a significant way. This leads to decrease in the productivity by more than 50% in major crop plants which are growing word wide (Bray et al., 2000). Increased water stress, reduction in rainfall and increased air temperature are the major reasons for yield decline in wheat and paddy crops in many parts of South Asia. The average increase in temperature per decade is measured to be 0.28 ºC over land and 0.12 ºC over ocean and predicted that it is likely to rise further to a maximum of 2.5 ºC by 2050 and 5.8 ºC by 2100 (Jones et al., 1999; Grover et al., 2011). The principal abiotic stresses in India are drought or soil moisture stress, high temperatures, soil salinity/alkalinity, low pH and metal toxicity stresses that affect nearly two-thirds area forming parts of the arid and semi arid eco systems (Grover et al., 2011).
