    The pressing need for increased agricultural production in the years ahead can only be met by more efficient use of our land and water resources including more widespread and better irrigation in those regions where rainfall is inadequate. Production gains will be shortlived unless the attendant hazards of salinization, water logging and lowered fertility are kept in check by effective planning and management based on a thorough understanding of the soil conditions. Soil survey and land classifi cation are generally accepted essential preliminaries to investment in irrigation development. This publication aims to describe the special requirements of soil survey for irrigation development, and assumes that the reader is familiar with basic soil science and soil survey techniques.

    In the temperate zones of the world a favourable balance exists between input and decomposition of organic materials in the soil. This balance is influenced by climatic conditions and the inorganic constituents of the soil, in which the amount and type of clay minerals play an important role. the plant growth caused by the use of mineral fertilizer increases not only the economically important parts of the plants, but also the growth roots and crop residues. Furthermore, in many farms animal exc reta is used to maintain the level of soil organic matter in arable land.There are some interactions between certain clay minerals and fractions of soil organic matter which act as favourable factors for soil productivity and for plant production.

    Advances in the assessment and monitoring of salinization and status of biosaline agriculture
    Report of an expert consultation held in Dubai, United Arab Emirates, 26–29 November 2007

    The causes of salinity and sodicity, which vary between countries and regions, need to be identified, assessed and monitored carefully so that they can be managed and controlled. There is a need for practical and cost-effective methodologies for assessing, monitoring and mapping the extent and distribution of salt-affected soils; for identifying the causes and sources of the problem; and for choosing management options and evaluating the effectiveness of those options. The object ive of the Expert Consultation on Advances in Assessment and Monitoring of Salinization for Managing Salt-affected Habitats was to exchange experiences with data collection and analysis for the assessment and monitoring of salinity and sodicity, with particular emphasis on practical applications at local, national, regional and global levels. The Meeting on the Status and Progress of Biosaline Agriculture of the Inter-Islamic Network on Biosaline Agriculture was an opportunity to present the work of the hosting institution and to exchange information between the two Networks.
