Descripción

The main causes and sources of the salt-affected soils in Cuba, their extension and distribution by Province,the definition used to describe the saline soils, the environmental and economic impact of the salinity in the country, thetechnological solutions use to combat this phenomenon are pointed out. Some aspects on the National Plan are discussedfor the improvement and handling of affected soils, as well as the research requirements and the international cooperation.It is concluded that the studies developed in Cuba have provided evidence on the current phase of the salinization processof soils. However, it is still necessary to gather, validate and store sufficient reliable quality data susceptible to be verified orcalibrated according to a geographical information system in order to develop a strategically recovering plan. In addition, itis necessary to develop an early warning system to prevent the spread of salinization and to establish techniques ofimprovement, management and rehabilitation of salt-affected soils. The execution of cooperative national and internationalprojects of technical and economic assistance are essential to: (1) increase the efficiency of the national action plan againstthe salinization, (2) enhance the soil productivity, and (3) provide local employment in complementary activities to theagricultural production.
