  • Available soil maps  Soil maps were produced through a national

    project (National Soil Map and Land Use Project, NSMLUP) carried jointly by the Ministry of Agriculture (MoA), Royal Jordanian Geographic Centre and Huntings Technical Service (UK) during the period of 1989-1995.

  • All maps are available as hardcopy sheets (Atlases) while all profile and pits were saved in Jordan Soil and Climate Information System (JOSCIS), held by the MoA. In this database, profile description of

    sampled sites is available. Detailed physical and chemical analysis is available for some profiles and sites at levels 1, 2, and 3.

    Example :Soil mapping units (level 1) with descriptive information

  • Soil mapping units, level 1 with description related to each unit. Field observations distributed in this mapping unit with related

    information

  • Soils at semi detailed level : level 2 scale 1:50000

  • Example on soil mapping units at level 2 with descriptive information linked to each soil mapping unit in GIS

    environment.

  • Soils at detailed level : level 3 scale 1:10000

    Soil maps at level 3 are not available digitally, otherwise they are found in Atlases of MoA.Each soil mapping unit is described with a code including: soil series, depth, stone/rock, and slope.

  • Land cover / land use maps:

    land cover/ land use maps are only covered at two scales with limited areas in Jordan: 1:50000 and 1:10000 as shown in below figures. These maps represent current land use. These maps are only available as hardcopies found in the atlases of MoA.

  • Potential land use maps:

    • Based on climatic records and historical survey, a general map of potential land use was delineated by Taimeh (1989) at a very small scale to characterize the country into different regions of capability. Basically, the map followed similar pattern of rainfall and bioclimatic zones of the country figure .

  • Rainfall isohyets in Jordan

  • Potential land use maps • More detailed maps were prepared through the NSMLUP

    (MoA, 1995) where land suitability code was assigned for each soil mapping unit.

    • The whole approach was based on biophysical factors

    criteria of land quality including soil physical and chemical properties, rainfall and temperature and land capability.

    • Suitability rating was coded for different land utilization

    types (LUT) including: 1. rainfed arable, 2. rainfed trees, 3. irrigation, 4. forest and 5. rangeland with controlled grazing.

  • • More detailed studies and research (Makhmreh, 1996; Harahsheh et al., 1998; Mazahreh, 1998; Al-Rashdan,1999; Al-Shoubaki, 1999; Ziadat, 2000; Al-Bakri, 2005) were carried out for different parts of the country at detailed and semi- detailed levels.

    • Results from these studies indicated an obvious shift between

    existing and potential land use, the fact that emphasizes the urgent need for sustainable land use options and policy.

  • Surveyed field observations are distributed all over Jordan. Available pits and bores counted in the MoA is 41613.

  • Soil observations including pits and bores database:

    • Data that were readily available from the (JOSCIS) database are: Rainfall, soil depth, temperature, available water holding capacity, slope, altitude, surface stoniness, erosion type and class, surface cover type (stones, boulders, rockiness) and percentage, and drainage class.

    • In addition, some data about salinity, alkalinity, and Calcium Carbonate percentage were available from the National Soil Map and Land Use Project reports.

  • Additional available maps

  • Al-Eisawi (1985) has recognized thirteen vegetation types in Jordan. Recent work by Albert, et al. (2003) indicated up to 19 recognizable types. Some types are strictly confined to one of the bioclimatic regions.
