Impact of climate change on cereal production in the highlands of eastern Algeria

The results obtained indicate a favorable climate change for cereal yields. This change in climate was expressed by increase in maximum temperature of 1.45°C, minimum temperature of 1.26°C and 2.5 mm increase in precipitation. It was also observed that change in climate increased the total production of wheat to 16544.4 tonnes during the studied periods of 1990 to 2004 and 2004 to 2014 due to improved productivity of wheat to 6.33 tonnes/ha. It was also observed that different durum wheat producing regions in eastern Algeria did not differ significantly in respect to production. On the basis of this study, it can be concluded that climate change had positive effect on durum wheat production in the Bordj Bou Arréridj province of Algeria.
