Shift Observation of the Zones Diematic Agriculture using Data of Actual Rain fall over the Iraq (a study of climate changes)

Abstract

This research aims to determine the relationship of spatial scales to riparian cultivation in Iraq, using actual rain data. In this research, a statistical analysis was carried out using the meteorological data of the Iraqi Meteorology in fifteen climate stations distributed spatially as aerial land control points for the total area span of Iraq, and in order to monitor the change in their quantities, the temporal dimension of the total of these data is determined in a series that spanned from (1952-2018) within Seasonal sequences (fall, winter, spring) were divided into three periods to achieve comparison evidence.

  In the practical analysis, the research aligns with the use of the averages method and the use of GIS technology to monitor spatial changes in crawling ranges, and it has been shown that there is a relationship between what is required by ritual agriculture in Iraq and the spatial ranges eligible for cultivation, and the research revealed through the sequence of studied periods the existence of spatial crawling of lines Iso Rain fall shows the most spatial ranges for diminishing rains and the occurrence of a spatial creeping of the ritual cultivation ranges in northern Iraq within the category qualified between (400-710 mm) from the northeast to the central eastern parts, which are the important spatial ranges for ritual cultivation. The percentage of changes in the spatial ranges of ritual cultivation in Iraq between the duration of the general trend from the last by one and within rain lines between 400-610 mm by (26%), to decrease its percentage within the period of the last decade (2008-2018) to (11%), while Agricultural land exposed to drought within the critical marginal rainy ranges increases by (34%) in the category of rain lines between (77 - 140 mm) and by (36%) in the rainy lines category located between (150 -240 mm) and by (7%) in The category of rain lines lies between (250-390 mm). This may put pressure on surface water resources, which are the last to decline due to lack of rain.

And what the research confirms is that the opportunities for ruminant agriculture in Iraq will fail in many spatial ranges, and here it was necessary to confirm our recommendation to go towards modern irrigation methods, including the method of spraying to ensure the sustainability of the production of ruminant agriculture.
