Conference paper


In recent years the utilization of halophytes has received increasing attention. Climate changes, which the senior author predicted some 30 years ago, have in the meantime reached such dimensions that economists, politicians and the general public are now ready to react to this warning given earlier by a few ecologists. The present meeting in Tunis discussed the major topics that the members of International Society for Halophyte Utilization (ISHU) could recommend for action to politicians and to the scientific community. These topics comprised: salinity tolerance types and levels for species of interest; selection of potential cash crop halophytes; genomic analyses; greenification of deserts and Sabkha landscapes; and future research and development topics. Several new points for the halophyte research group were: the discussion of genomic and proteomic analyses and their value for salinity-tolerance improvement of cash crops; the use of satellite remote sensing for the assessment of net primary production (NPP) from the normalized difference vegetation index (NDVI).The classical method to calculate average annual NPP from meteorological and soil fertility data was compared with the correlation of annual NPP values from satellite remotely assessed by NDVI; and the salinity tolerance tests and the multiplication of suitable plants with tissue cultures were explained in greater details. For the presentation of these topics, we include here information obtained from other authors, which are used with their permission.
