Agricultural land and water use is a very important topic in today’s world. In the western states, agriculture accounts for 90% of the water consumption (USDA “Irrigation and Land Use” 2015). 51% of the entire United States (including Alaska,) is dedicated to agriculture(USDA “Irrigation and Land Use” 2015). The water that is used for irrigating crops is lost as runoff, or seeps into the ground, and cannot be recycled or used again. Vast expanses of land are used in the United States for growing the amount of crops needed to feed its population.…
2 Since, around “60 miles” of its frequency are “dry”, as the “flow diverted to irrigation”. 2 Furthermore, all “river in the arid Tulare Lake basin” has “dry” sections due to alterations into “irrigation channels aqueducts”. 2 Additionally, about “80,000 acres of marshland border Suisun Bay,” as where the water develops from the “maze of Delta channels” and it goes through to the “San Pablo Bay and San Francisco Bay”. 2 However, still till this day the remnants of “Suisun Marsh” is still the biggest “salt marsh” in the “lower 48 states” which, is on behalf of the “12 percent” of the entire “wetland acreage left in California.”…
In this essay I am going to be talking about desalination and large scale desalination of the ocean. I’ll also be talking about what desalination is, and what it can be used for. I'll be researching different methods people use it. Also including ways that desalination have caused problems and damaged the environment.…

2. What do you think would happen if you watered your houseplants with salt water?…
Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water, watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt, the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth of the plant. I also had a few difficulties in the duration of this experiment which were the sunlight on the plants direct which made the plants to begin to die and also the highest salinity plant was not growing.…
When looking out onto the beach, there are various sections that are visibly different from one another. These zones are due to seaweed, the size, density and more obviously colours. The most common colour seaweeds are browns, from the phaeophycae family. During the day, as tides come and go, the seaweed becomes saturated and then starts to dry out, called desiccation.…
Small variations in salinity can make a monumental difference on the water cycle and the ocean circulation. Trouble can also arise when saltwater gets transferred onto the earth. That can damage the soil and wreck habitats! There are two types of salinity, primary and secondary salinity. Primary salinity is when water or soil naturally has a high amount of salt in it, like in a salt lake. Secondary salinity is caused by humans. It can be caused by clearing too much land, which makes the groundwater rise to the surface and the salts inside dissolve into the soil.Secondary salinity has two main forms of which it happens. The first is dry land salinity; when more water enters the groundwater than is taken out, so it can enter vegetation on land and become absorbed by the soil. There is also Irrigation salinity; (Irrigation is the act of flowing water over crops to nourish them), salts can collect in the topsoil under the irrigation. Too much irrigation or poor water are the main causes of…
Perhaps the most contentious aspect of desalinization, however, is how to dispose of the highly concentrated salt brine left over from the plant’s water cleansing. Every hundred gallons of desalinated seawater yields fifteen to fifty gallons of drinking water (depending on the process, and the water to begin with), and fifty to eighty gallons of brine. Where, the highly concentrated brine is flushed back into the sea. It can destroy aquatic species, particularly those in the egg or immature phase of development. (Prud’homme336).…
Desalination is a great way to provide more water for people. Taking salt out of seawater…
One consequence of human use of water is the wasted water resulted from inefficient irrigation. Less than half of the freshwater we use for irrigation is actually absorbed by crops. Wasteful practices like “flood and furrow” irrigation, which involve liberally flood fields with water, use up water unnecessarily because it may evaporate from standing pools in the field. This kind accounts for 90% of worldwide irrigation. Overirrigation leads to waterlogging and salinization, which ultimately affects 20% of worldwide farmland and loses $11 billion in farming income.…
What is desalination? Desalination is the separation process of removing or reducing excess salts and other mineral from substances. 1 The process of desalination may be used on different substances however this paper will focus on the desalination of water. The desalination of water is very important to human and animal life. For centuries humans have used the process of desalination to obtain water safe for consumption.Various methods of desalination have been produced however only some of those methods are widely used today.…
In other hand to food supply, seaweed has vitamin which benefits for natural beauty. It improves the…
An integrated method is developed to utilize to a maximum extent the fresh biomass of seaweeds such as Kappaphycus alvarezii that can be crushed to release sap and where the sap is useful as a potent liquid fertilizer after suitable treatment with additives and dilution while the residue is a superior raw material for extraction of κ-carrageenan, thereby enhancing the value of the seaweed. Other advantages of the invention include a reduced drying time and drying area to obtain the raw material for κ-carrageenan production in dry and storable form, a reduced cost of transporting and storing this raw material because of its lesser bulk, easier handling due to its free flowing granular nature, and its direct use for gel preparation in certain applications.Inventors: Karuppanan Eswaran, Pushpito Kumar Ghosh, Arup Kumar Siddhanta, Jinalal Shambhubhai Patolia,Chellaiah Periyasamy, Aditya Shantibhai Mehta, Kalpana Haresh Mody, Bharatkumar Kalidas Ramavat, Kamalesh Prasad, Mahesh Rameshchandra Rajyaguru, Singaram Kulandaivel Chennur Radhakrishna Reddy, Jayant Batukrai Pandya, Akhilesh Tewari…
