ABSTRACT
Coastal areas are defined as the interface or transition areas between land and sea, including large inland lakes. The coastal zone is an area of convergence of activities in urban centres, such as shipping in major ports, and wastes generated from domestic sources and by major industrial facilities. Rice is suitable for rehabilitating these soils because of its ability to grow under flooding and its high potential for genetic improvement. Salt-tolerant rice varieties also offer great potential to grow rice in marginal lands, which are usually left fallow particularly during the dry season because of high salinity. Coastal areas are different from inland areas. Salinity problems in coastal soils is caused during the process of their formation under marine influence and subsequently due to periodical inundation with tidal water and in case of lowlands having proximity to the sea due to the high water-table with high concentration of salts.
