They have been planted ( or re-planted ) in some places to lower the water table and reduce soil salination.
22.
Leakages from the canal have created lakes and ponds along the canal and the rise in groundwater has caused widespread soil salination.
23.
In December 2014, a fire damaged the only de-salination plant in Maldives plunging it into a severe water crisis.
24.
Because of the young geological age of the reef islands and atolls and high level of soil salination the soils is relatively poor.
25.
Fertilizers deplete soil of organic matter and trace elements, cause salination and suppress mycorrhizae; they can also turn symbiotic bacteria into competitors.
26.
Soil salination is the accumulation of free salts to such an extent that it leads to degradation of the agricultural value of soils and vegetation.
27.
The Shimazu clan of the Japanese salination, famines were frequent, and the population of the islands further decreased until the early Meiji period.
28.
In irrigated lands, subsurface drainage may be required to leach the salts brought into the soil with the irrigation water to prevent soil salination.
29.
Without these forests, tidal surges would lead to the salination of fresh groundwater further inland which would contaminate supplies for domestic and agricultural uses.
30.
It is thus likely that within a century the nation's arable land will become subject to increased soil salination and will be largely submerged.
