Abstract
Climate change based on precipitation and temperature variability is a major concern in the world, particularly in the Horn of Africa, including Eritrea, which has led to severe droughts in poverty and hunger in the region. In this study, the long-term trends and interpolation methods were used to evaluate and evaluate the average annual rainfall and temperature, and the drought condition was analyzed by using standard precipitation Index (SPI) (1930 – 2010).The results showed that the long-term trend of annual precipitation was obviously decreased and the temperature increased significantly. Relatively, the Highland (around Asmara) receives above 466 mm rainfall, with an average temperature of 20.13oC. In the last eight decades, Massawa and Assab recorded minimum rainfall (221 mm) and the highest temperature (> 28.16oC). The country has experienced moderate to severe droughts since the 1960s, particularly in 1966, 1984, 1990 and 2009. We conclude that, over the past 81 years, climate change and drought have been serious environmental problems in Eritrea, and this study may be of great importance to policymakers in formulating and establishing appropriate plans to address and control current environmental issues.
