a long walk to water where does salva live
A Long Walk to Water Salva is a young 11-year-old boy separated from his family during a war in what is now South Sudan because of the Second Sudanese Civil War. He has to walk for weeks with only the hope that one day he will find his family again. Salva also struggles to find food and water to survive along with avoiding gunmen, lions and other threats. Salva leads 1500 fellow lost boys to a refugee camp near the Gilo River. Seven years later, he arrives in America. He lives with a family in Rochester, New York. Many years later he finds his father and starts a volunteer group to build wells in South Sudan called Water for South Sudan.
Soil salinity Salinity is an important land degradation problem. Soil salinity can be reduced by leaching soluble salts out of soil with excess irrigation water. Soil salinity control involves watertable control and flushing in combination with tile drainage or another form of subsurface drainage.[3][4] A comprehensive treatment of soil salinity is available from the United Nations Food and Agriculture Organization.[5]
