Even though, there is a general understanding on the impact of climate change and variability on agricultural crops,the spatial and temporal variability of these impacts remains yet uncertain. Thus, modeling the likely impact of climate change on cereal crops at local level is crucial for developing possible future options of adaptation and mitigation strategies. This research was conducted with the objective of modeling the impact of climate change and variability on sorghum production....

2 P. O. Box 3057, Mekelle,Tigray, Ethiopia Abstract: Despite Potato (Solanum tuberosum L.) is regarded as a high potential food security crop, its production in Ethiopia is much less than the average world potato production. Potato is sensitive to high temperature and moisture deficits. For this reason, potato production is said to be vulnerable to the anticipated climate change. The objective of this study was to assess the impacts of projected future climate on potato yield taking into...

BackgroundObesity has become a global health problem.Obesity and overweight pose a major risk for serious diet-related chronic diseases, including Type 2 diabetes, cardiovascular disease, hypertension and stroke, and certain forms of cancer [1].The World Health Organization (WHO) estimated that by 2005, at least 1.6 billion and 400 million people aged above 15 years were overweight and obese respectively.It further projected that by 2015, these statistics will increase to 2.3 billion for...

Background: Obesity and overweight pose major risk for serious diet-related chronic diseases, including Type 2 diabetes, cardiovascular disease, hypertension and stroke, and certain forms of cancer. Even though there is no well-documented information recently, chronic diseases that are directly or indirectly related to overweight and obesity are increasing in Ethiopia especially in urban areas. Objective: the main aim of this study is to determine the prevalence of childhood overweight and...
