Climate variability and change in Bihar, India: challenges and opportunities for sustainable crop production
Climate change and associated uncertainties have serious direct and indirect consequences for crop production and food security in agriculture-based developing regions. Long-term climate data analysis can identify climate ...
Meteorological drought assessment in north east highlands of Ethiopia
(Emerald Publishing Limited, 2018)
The purpose of this paper is to investigate the patterns and trends of drought incidence in north east highlands of Ethiopia using monthly rainfall record for the period 1984-2014. Design/methodology/approach Standard ...
Analysis of risks in crop production due to climate change in the Central Rift Valley of Ethiopia
(Academic Journals, 2015)
This study was conducted to investigate historical climate dynamics and the resultant risks at four sites (Meki, Melkassa, Miesso and Ziway) in the Central Rift Valley of Ethiopia. It involved analysis of rainfall and ...
Maize crop nutrient input requirements for food security in sub-Saharan Africa
Nutrient limitation is a major constraint in crop production in sub-Saharan Africa (SSA). Here, we propose a generic and simple equilibrium model to estimate minimum input requirements of nitrogen, phosphorus and potassium ...
Potential benefits of drought and heat tolerance for adapting maize to climate change in tropical environments
Climate change and population growth pose great challenges to the food security of the millions of people who grow maize in the already fragile agricultural systems in tropical environments. There is an urgent need for ...
Assessment of common bean (Phaseolus vulgaris l.) Seed quality produced under different cropping systems by smallholder farmers in eastern Ethiopia
(African Scholarly Science Communications Trust, 2014)
One of the major causes of low yield of common bean in Ethiopia is the shortage and/or inaccessibility of high quality seed. In the Hararghe highlands of eastern Ethiopia, farmers often use common bean seeds produced both ...
Trend and variability of rainfall in Tigray, Northern Ethiopia: Analysis of meteorological data and farmers' perception
(Academia Publishing, 2013)
Rainfall is the most important but variable climatic parameter in the semiarid tropics. In this study, the trend and variability of rainfall were compared with the perception of farmers in northern Ethiopia. Daily rainfall ...
Wheat crop response to liming materials and N and P fertilizers in acidic soils of Tsegede highlands, northern Ethiopia
(Science Publishing Group, 2013)
A greenhouse experiment was carried out on acidic soils collected from the Tsegede highlands of northern Ethiopia, where wheat production is severely constrained by soil acidity, to evaluate wheat crop response to the ...
Quantifying the impact of weather extremes on global food security: A spatial bio-economic approach
This study uses a spatial bio-economic modelling framework to estimate the impact of the 2012 weather extreme in the USA on food security in the developing world. The study also quantifies the potential effects of a similar ...
Outlook of future climate in northwestern Ethiopia
(Scientific Research Publishing, 2012)
Climate change is described as the most universal and irreversible environmental problem facing the planet Earth. While climate change is already manifesting in Ethiopia through changes in temperature and rainfall, its ...
