When properly applied ( watering well in excess of evapotranspiration, maintaining soil structure for excellent drainage ), brackish-water irrigation does not result in increased salinization of the soil.
42.
In 2013 Environmental authorities started a program in order to defend and recover they first line of defense against advancing waters and effects of salinization of farmlands; fixing their Mangrove forests.

Farmers use the gravitational or surface irrigation which is one of the most inefficient methods of irrigation, creating several problems including a poor water use efficiency practice, salinization, and contamination.
44.
The fallow land is continuously rotated throughout the years, so that there exists no permanent fallow land, except along the fringes at the base of the fan where soil salinization occurs.
45.
Land degradation occurs because of clearing land for agriculture, the planting of non-native buffelgrass for grazing, the cutting of forests, overgrazing of natural vegetation and soil salinization from irrigation.
46.
Over the past 50 years, the destruction of habitat surrounding agricultural land has degraded approximately 40 % of agricultural land worldwide via erosion, salinization, nutrient depletion, pollution, and urbanization.
47.
And it's not that they disagree with his plan to reverse the deadly salinization of their neighboring state's sea, a victim of sewage and of drain water from nearby farms.
48.
Depletion may occur through a variety of other effects, including overtillage ( which damages soil structure ), underuse of nutrient inputs which leads to mining of the soil nutrient bank, and salinization of soil.
49.
Land transformation, the use of land to yield goods and services, is the most substantial way humans alter the Earth's ecosystems, and is considered the driving force in the acidification and salinization ).
50.
Unfortunately, the primitive construction of the canal allows almost 50 percent of the water to escape en route, creating lakes and ponds along the canal, and a rise in groundwater leading to widespread soil salinization problems.
