Abstract   


  The research aimed to determine the spatial suitability of agricultural land  uses  in  the  Sheikhan  District,  using  the  Geographic  Information  Systems  program and its accessories represented by the toolbox. 

  (Arc  Tool  box)  and  spatial  analysis  tools,  including  the  Suitability  Analysis tools and the Model Builder application, where spatial and descriptive  databases were built and corrected and linked to each other to form a database  specific to the Sheikhan district and ready for the spatial analysis process. 

  The  problem  of  the  research  was  that  the  investment  of  land  in  the  Sheikhan District is not carried out according to an approach based on following  spatial suitability for growing agricultural crops in the Sheikhan District, and  the  lack  of  maps  in  the  Sheikhan  District  that  can  be  used  in  geographical  studies and planning, especially at the agricultural level. Therefore, the research  was  directed  To  survey  and  inventory  the  human  and  natural  geographical  potential of the district, and thus a geographic database was prepared for the  natural and human potential available in the district, and to evaluate the spatial  suitability of agricultural land uses in the district based on modern

geographical  techniques and the multi-criteria decision-making methodology (MCDM), and  to extract the weights of the human and natural variables affecting the district.  Agriculture  and  land  use  in  the  district.  This  was  done  by  relying  on  the  classification of the Food and Agriculture Organization of the United Nations  (FAO)  in  determining  levels  and  classes  of  suitability  through  implicit  integrations  between  geographic  information  systems,  statistics,  and  spatial  decision  support  systems,  as  well  as  developing  tools  in  the  geographic  information systems program to evaluate suitability. land for crop cultivation,  leading to determining the best use of the land according to the data obtained,  classifying  and  evaluating  the  suitability  of  lands  for  growing  general agricultural crops in the district, and then knowing the reality of agricultural  crop cultivation and the suitability levels of each crop and their geographical distribution in the district, relying on a model.

  ( Runak  Agriculture  Suitability)  in  the  (AGLA)  program,  which  is  the  first research in Iraq and the Arab world to adopt this program and model in  determining  the  suitability  of  agricultural  crop  cultivation,  as  this  program  includes  a  standardized  model  within  indicators  of  the  requirements  of  each  crop according to the standards and indicators of the FAO and access to Results:  This research ended with the construction of a cloud geographic information  base, where spatial documents of the levels of suitability of agricultural land for  agricultural crops were uploaded to the Onlien ARC GIS platform. 

  Maps of land suitability types for growing crops revealed a number  of  facts, namely that the district enjoys fertile land with good and average types of  land suitability for agricultural production, and that the uses of agricultural land  in the Sheikhan district varied between unsuitable lands for growing crops in the  northern  regions  and  suitable  lands.  Few areas  in  the  mountains,  medium  suitability in undulating areas, and high suitability in plain areas . 

 This research presented proposals, the most important of which was after  building a spatial and descriptive database on the capabilities of the judiciary  with its natural and human resources, on the basis of which various levels of  cultivation of general agricultural crops were reached and the suitability of the  levels and varieties of each agricultural crop. Therefore, decision-makers must  contribute  to  maximizing  the  cultivated  areas  and  Increasing  agricultural  production in quantity and quality by investing all available natural resources in  the district in order to build a sustainable agricultural system.
