Global Water Crisis: The Potential of Cash Crop Halophytes to Reduce the Dilemma

Abstract

This paper summarizes the most important reasons for the shortage of drinking water. The shortage of freshwater is mainly caused by the increase of water consumption for the human population and their domestic animals. There are additional shortages generated by the salinisation of irrigated soils and the climate changes causing the extension of dry regions. This is especially true for the southern tropical hemisphere.
