Dryland Research Paper
SALINITY Problems arise in the world due to salinity, as when the salt gets on to the top of the soil.....it causes disaster to the plants and trees. Salt comes in many forms in the natural environment—calcium, magnesium, carbonate, sodium chloride, bicarbonate, and sulphate. Many landscapes are naturally saline, but secondary salinity isn’t so natural, occurring when salts from deep within the earth are dissolved and deposited into soil and water as a result of human activity. This can happen in one of two ways:
Dryland salinity - from removal of deep-rooted plants
In dry regions, deeply-rooted perennial plants, such as shrubs, trees, and grasses, play an important role in regulating groundwater …show more content…
It also requires significant funding. The Australian government, for instance, pledged to spend nearly $8 million on salinization remediation plans to 2008.
Should it continue? On one side, there are those who are against
Without remediation of soil salinity, great problems lie ahead
Without long-sighted solutions, the problem of salinity, including loss of agricultural land, devastation of ecosystems, and the costs associated with damaged property, will continue to increase. In the US, it is estimated that 10 million hectares of land is lost to salinity every year. The challenge is equally serious in Australia.
Environmentalists have been drawing attention to this growing crisis for years, and only after seeing the effects of salinity are individuals and governments coming to terms with the magnitude of the problem. Failure to address salinity could result in widespread crop failures and even more devastating loss of biodiversity.
Should it continue? On the other side, there are those who are all for it
