Abstract

To plant life, salinity is just one inimical factor of the environment. To man, salinity creates a problem due to its effect s on his crop species which are predominantly sensitive to the presence of high concentrations of salts in the soil. Difficulties arise IPresent address: School of Biological Sciences, University of Sussex, Falmer. Brighton, United Kingdom. FLOWERS, TROKE & YEO because of the widespread nature of saline soils and are compounded by the geo­ graphical distribution of man's population and by agricultural practice,which has largely succeeded in increasing salinization in arid and semiarid lands. Although the sources of salinity are clearly recognizable (see 192), it has been difficult to gauge their worldwide effect due to the dearth of information about the areas of land involved. Recently,however,within the framework of the production of a World Map of Salt Affected Soils by the International Society of Soil Science, more data have become available. The total area in the countries so far mapped­ Australia (138) and Europe (181)-is vast (some 3 X 1()6 kml), and while maps of the saline land in the remaining areas of the world have as yet not been completed, estimates indicate there to be at
