This research conducted in the Institute of Technical / Mosul / Plant Production Department, using the method of analysis of spatial and temporal of the lands covered by the desertification in the province of Nineveh, which were Baaj, Al-Hadar, Telapta and Al-Shemal region . Was reached through a study that desertification is a form of degradation which affects lands in arid and semi-arid regions such as Iraq, including Nineveh province, under the influence of natural factors ( environmental ) which is not suitable , such as climate factors , which include high temperature , atmospheric drought, low rate of relative humidity, intensity and direction of the wind in summer season , the high value of evaporation , drought of soil , low rates fall Raining in winter , the intensification of solar radiation ,high temperature, great warming disparity between winter and summer and between day and night , changes in atmospheric pressure , addition to the lack of water surfaces , drought of valleys . Thus these factors combined caused the demolition of the soil profile, the soil structure and the cohesion of the particles due to the demise of organic matter which associated the soil particles were represented by humus material, which leads to a decline in the productivity of the land and the impact on food security. Either human factors , they include in mainly form environmental pollution due to excessive exhaust of natural resources , loss of the phenomenon of the natural balance and self-renewal in the biosphere , not rationalize the consumption due to population increase , expansion of human activities , not applying the clean technology , increasing the use of polluted traditional energies , which produced the polluted matter as solid, liquid and gaseous which caused an imbalance in the ecosystem which is global warming, as well as the misuse of the land environmentally and mechanically in the cultivated operations of soil and crop with the following traditional irrigation methods which caused the increase of soil salinity also overgrazing non alternately, methods of deforestation , which forest is green belt , windbreaks to dust and sand storms . As a result of the interaction of environmental with human factors that the reaction is reflected in the form of the ecological imbalance called desertification. Through spatial analysis was evaluated the quality of desertification in the region the situation from medium to severe because the soil is still present despite the deterioration of soil fertility , loss of vegetation , low productivity but requires processed quickly otherwise become an a environmental disaster , because the speed of desertification in the region between 5-10 km / year , through the spatial analysis of desertification can be classified ; Baaj in first place Al-Hadar second place , Telapta third place and the Al-Shemal aspect region fourth place, where areas are represented above 20 %, an area of 1,385,843 dunum from total area of farmland on the level of province . This is clearly evident from the survey and spatial analysis, which caused the displacement, harmed (30000) human, in Baaj 134 village and (70) of the village population in others. The destruction of 75% of the livestock in addition to loss of biodiversity and degradation of soil and vegetation cover. Through the temporal analysis for areas covered by desertification can be seen that the time series between 1941-1985 was rainfall at; 338 ml / year. Can be conclude that during the 44 years the rate of precipitation is not suitable for the needs of agriculture , particularly crops of wheat , barley and natural grassland except with implemental irrigation , which did not witnessing the areas above then the phenomenon of desertification , where continued Londoner rates fall of rain water that reached 130 mm / year for the period of time confined between 1996 to 2000 where not harvested winter cereal crops , between 2002-2012 were the rainfall vibrant, through(11) years reached as average 303,7 ml/ y and the year 2013 increased the rainfall to 472,9 ml/ y ,through the past years increased temperatures rates , increased heat waves, hot days in summer as well as the irregular distribution rainfall , increased frequency of droughts ,increased their intensity in the region , was the very severe of drought in 2008 reached severity -2.48 by techniques of standard precipitation index (SPI) also increased sandstorms in terms of repetition and intensity reached 32 storm , as well as sintering heaven 71 days of dust thick , were critical stage in the water requirement for cereal crops in 2001 , either increased evaporation value in the year 2000 is the highest ,average of relative humidity 52% for years2002-2012,the falling dust was 13gm/m2/month in 2012 and suspended dust in atmosphere as average 1,394 microgram/m3, this was highest rate by comparison with Baghdad &Basrah proninces.The result of non-stability of environmental status and vibrant raining through past years, where decreased groundwater recharge and their levels, also increased their salinity and degraded the quality . The negative impact of climate factors within the time series reflected negatively on soil and deteriorated their physical, chemical, and biological properties, causing desertification which negative reflected on winter farming production and vegetation cover.

The N2- fixing cyanobacteria are important agents in crop fields contributing to the primary productivity and nitrogen economy of the soil. In the present study, diversity and abundance of N2- fixing cyanobacterial population were investigated in the rice ecosystems of the Brahmaputra floodplain in response to the soil physico chemical properties in four different seasons. Altogether 51 species of N2- fixing cyanobacteria belonging to 15 genera under 7 families were recorded in two common rice cropping systems - double rice cultivation (RR) and rice rotated with mustard (RMR). Among the isolated genera, 10 were heterocystous and 6 were non heterocystous. The genera Anabaena (25%) and Nostoc (19%) comprised of the highest number of species followed by Calothrix (8%) and Phormidium (8%). Results of relative abundance also revealed the dominance of Anabaena and Nostoc in the rice ecosystems of the valley. Pearson’s correlation analysis showed significant correlation between population number of N2- fixing cyanobacteria and soil physico-chemical properties. Canonical component analysis (CCA) justified the seasonal pattern of population abundance along with the concomitant change of soil parameters like temperature, moisture, pH and available phosphate in the rice field soil of the valley.
