Dryland Salinity In Australia
What is Salinity?
Salinity – Salinity can be defined as the condition where the quantity of salt causes problems in the soil and impacts in the landscape. The term salinity can be classified in numerous diverse ways: irrigation salinity, dryland salinity, urban salinity, river salinity and industrial salinity. These contrasting types of salinity are arranged to how and where the salt has been located and what the effects are.
An example of salinity is the amount of salt that is measured in a fish tank in a house.

What is Drought?
Drought – Drought is a lengthy period of time of no rainfall bringing about considerable damage to crops and a loss of yield. Occasionally mentioned as “creeping phenomenon” as it constantly adjacent areas successively.

Map of Salinity: Above is a map of Dryland Salinity risk. This map shows the amount of dryland salinity in the states of Australia. There appears to be a high amount of salinity in Western Australia, South Australia, Tasmania, New South Wales and Tasmania. There are medium dryland salinity risks in every states as well as the amount of low dryland salinity. There is nil (zero) amount of dryland salinity mainly in Western Australia, South Australia. There also few nil salinities in Northern Territory, Queensland, New South Wales. The areas with the fewest nil salinity is Victoria and Tasmania.
Map of Drought: From the map shown above the rainfall deficiencies of Australia. There is little serious rainfall deficiency in Western Australia, Tasmania, Northern Australia. In South Australia, it displays serious, severe and lowest on record rainfall deficiencies. This is also demonstrated in Queensland with only very little lowest on record rainfall

In this case, the soil that has limits to amount allowed to take in rainfall can determine the rates of run-off. As a result of this, a large quantity of destruction can be done to roads, fences, dams, land and wetlands of cultivation.
Irrigation – Water that have been contaminated with salt that is left on surface of the ground or plantation leaves after vaporization. Thus, any sort of system involving irrigation has the possibility to come across with a rising increase of salt to the soil.

What are the effects of Drought?
Hunger and Famine – Since water is a major source for food crops along with the sun, it is reliant on water to supply natural resources for the plants. Grass and food grains are all dependent on water to provide them growth, when there is a drought, they are drastically affected. Drought is something that affects growth and the lives of food sources, when gone, people begin to starve. Famine is can be defined as limited amount of food sources are severely affected, crop failure or the balance of population are involved in famine. Famine is what occurs after a long period of time of drought.
Thirst – Although humans can survive for weeks without any food, since all living components are reliant on water to live, people will only last less than a week without

    The Australian environment also has relative geological stability. The last volcanoes were active many years ago, and the last of the glaciers shrank and melted many years ago. We only had volcanoes and glaciers because of the separation of Pangaea therefore making the Continental Drift Theory. There is little geological activity to create or refresh fertile soils. The majority of Australia is very old rock therefore means that we have very poor soils and recently alluvial soils which also have poor nutrients.…

    The chemical components that make up salt are the fused elements of sodium and chloride (Editorial Board, 2012). If there is abundance or very little salts present in dissolve fluids, there could be interference with routine cell functions. Plants depend on water for fluids within the living cells. Too much salt disrupts the flow of the necessary fluids to get to the roots. In addition, a disruption of the photosynthesis process which depends on water particles to carry oxygen and hydrogen atoms throughout the plant becomes stagnant. The salt, mixed with snow and ice, melts down to a watery substance that contains high levels of sodium chloride.…

    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…

    Water is a life resource for everyone. A situation between a drought and our resources being in danger with shortages of water in the region, is something that should not be trifled with. The state of California plunged into its third year of being affected by a record breaking drought. (Global Risk Insight) The Sacramento region was in desperate need of water this winter, with the high record of 52 winter days without rain (Sacramento Bee: Weather Report). Generally, the average time for rainfall encloses the time from late November to Mid April; and the months of the most rainfall occurs December through February.(Department of Water Resources) As parts of the country get drier, the amount of water availability will most likely decrease. The drought of 2014 is being noted as the most dangerous and driest drought California has ever seen.…

    The Dust Bowl

    The decade that became known as the "Dirty Thirties" was literally quite what its name implied-dirty! During the period of 1930-1940, located in the heart of the Great Plains of the United States, was a series of massive dust storms and long-term drought. Another well-earned nickname this region was known for was the Dust Bowl. The Great Depression occurred at this time as well and added to the suffering placed upon the many poor farmers of the Southwest region. What could have caused one of the worst and longest droughts in recent U.S. history? Unfortunately, decades of human influence from bad farming practices, loss of soil moisture, and depletion of vegetation helped create wind-blown erosion that shaped the massive dust storms and severe droughts. Other natural causes were unusual weather patterns: warmer Atlantic and colder Pacific sea-surface temperatures, feedback mechanisms from dry air, and a strong jet stream confined to the north of a continental high pressure system that left little chance for rainfall.…
