Structural Changes and Spatial Differentiation of Crop Production in Libya (1997-2007)

Structural change of crops in Libya has both naturally and anthropogenic influenced. The change has direct implications for human society as well as for the earth system. The processes that occurred in the structural changes of crop are tightly coupled to the processes occurring in other components of this system such as meteorological and hydrological. So, understanding the causes of vegetation variability and measurement of structural changes of crop to natural and anthropogenic influences are a great scientific importance. Libya as many countries had structural changes of planting, for example in Sabha direction of crops production had an inverse transformation in ratio to area, but due to the increased participation of sowing production and trefoil in total across all productions, by 92.4 % compared to 1997 and increased area of 228.631 ha. Most of structural change of crop production are observed in the settlements of Libya and associated with an increase in vegetation activity due to prolongation of the growing season caused by temperature rise. Mathematical-statistical method of successive coefficients determines six basic directions of use of sowing areas, that making it possible to analyze qualitative changes in the structure of the crops.
