Abstract:
The phenomenon of climate change is a universal one that has local influences for the differences of the nature and sensitivity of the environmental systems in each region. The agricultural activity in the region of the study in general and the agriculture of rice in particular has high sensitivity for climate change. The area of study is arid and depends basically on the water of Euphrates. Therefore, the study has a problem which is the indicators of climate change and their impact on the agriculture and production of rice in the governorate of Najaf and Qadissiya.The answer to this question was supposed that there are indicators in the area of the study in the climate element of the area which shed light on the agriculture of rice and production. In order to reveal these indicators and prove their existence, six climate stations distributed into two are in the area of the study. The record duration has been (1980 - 2012) to represent the general trend of the change indicate in the elements of climate. The climate features of the area of the study in terms of radiation, brightness, heat, pressure, and dust, moisture and rain through the method of average and annual collection of these elements. The objective is to know the nature and distribution all year long. Then, we will be comparing with the climate and the production of rice, the quantitative and cartographic method with their programming techniques that are developed were used in the field of study of the global climatechange. The statistical analysis of the annual average of the previous elements was conducted so as to know the general trend and the annual change. It became clear that the area of the study had its share of the change which occurred in the climate in general and in the climate of Iraq in particular. The indicator show clear indicators of the tendency towards increase and decrease.The results of the study found clear indicates of change in the climate represented in the regular temperature, the maximum and the minimum towards raise in the temperature and decrease of the solar radiation and the hours of brightness, as well as the wind speed. That would lead to the decrease of evaporation and the exudation and the water allocation of rice corps. The general trend of these elements and the extraction of the average annual change of these through the duration of the study in the season of rice growth (May - November Link results have shown in Najaf station and a relationship strong between the amount of production Mahso rice and cultivated area and the maximum temperature was an inverse correlation between production and variables of the actual brightness and wind speed and 65% of the changes in crop production due to these variables But in Diwaniya station show a strong correlation between the amount of production and cultivated area and the actual brightness and maximum temperature was leech inverse correlation between production and relative humidity, and 84% of the changes that have occurred in rice production due to the studied variables in this station
