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 ...
Maize crop nutrient input requirements for food security in sub-Saharan Africa
(Elsevier; Elsevier, 2019)
Can sub-Saharan Africa feed itself?
(National Academy of Sciences, 2016)
Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub-Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 ...
Outlook of future climate in northwestern Ethiopia
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 ...
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 ...
Modeling the effect of a heat wave on maize production in the USA and its implications on food security in the developing world
This study uses geo-spatial crop modeling to quantify the biophysical impact of weather extremes. More specifically, the study analyzes the weather extreme which affected maize production in the USA in 2012; it also estimates ...
Meteorological drought assessment in north east highlands of Ethiopia
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 ...
Effect of temperature on growth and sporulation of Botrytis fabae, and resistance reactions of Faba Bean against the Pathogen
(OMICS International, 2015)
Chocolate spot (Botrytis fabae) is a devastating disease of faba bean and reduces its production and productivity. Three controlled condition experiments were conducted to assess the effect of temperature on growth and ...
Risks associated with dry soil planting time in Ethiopia
(International Network for Natural Sciences, 2015)
Dry soil planting is practiced in response to variable rainfall onset in Ethiopia to maximize use of the full season. Rainfall data of >30 years for seven locations were used to evaluate dry soil planting opportunities on ...
Farmers' climate change adaptation options and their determinants in Tigray Region, Northern Ethiopia
(Academic Journals, 2015)
Exploring micro-level evidences is critical to fine tune effective adaptation options to cope with the adverse impact of climate change. In this regard, detailed studies on climate change adaptation options are not available ...
