    Abstract: Northeast Ethiopia is a semi-arid region that exhibits high rainfall and temperature variability. The impact of climate change has received a great deal of attention worldwide. This study focused on detecting trends in in rainfall (1983-2013) and temperature (1981-2010) at annual, seasonal and monthly time scales for six weather stations in semi-ar... Show More

    Abstract: In this research, we have investigated the effects of rainfall and temperature variability on wheat, Teff, Maize and Barley yield in Quarit district of West Gojjam zone. The data used in this study were temperature, rainfall and (Wheat, teff, maize and barley) yield for the period 1997 to 2016 and Origin 07 and Matlab software were used for the ana... Show More

    Abstract: Human beings are utterly dependent on nature particularly on the forest ecosystem services. Our health, economy, prosperity, and development are all connected to the forest ecosystem services. Forest ecosystems afford variety of the ecosystem services that human beings depend up on them. Ecosystem services are base for the survival of mankind and p... Show More

    Abstract: The rainfall modeling at regional scale remains a great challenge in the tropics because of the complexity of the processes that induce rainfall variability. Then the good parameterization of some atmospheric processes will be of great contribution towards the improvement of regional models. In this paper we applied wavelet transform on 2.5°×2.5° d...
