Understanding the weather signal in national crop-yield variability: Weather-signal in crop-yield variability
Year-to-year variations in crop yields can have major impacts on the livelihoods of subsistence farmers and may trigger significant global price fluctuations, with severe consequences for people in developing countries. Fluctuations can be induced by weather conditions, management decisions, weeds, diseases, and pests. Although an explicit quantification and deeper understanding of weather-indu...
متن کاملClimate change impacts on crop yield: evidence from China.
When estimating climate change impact on crop yield, a typical assumption is constant elasticity of yield with respect to a climate variable even though the elasticity may be inconstant. After estimating both constant and inconstant elasticities with respect to temperature and precipitation based on provincial panel data in China 1980-2008, our results show that during that period, the temperat...
متن کاملImpact of Climate Variability on Cool Weather Crop Yield in Ethiopia
The research examined effect of climate variability on yield of the two dominant cool weather cereals (wheat and barley) in central highland and Arssi grain plough farming systems of Ethiopia using eight round unbalanced panel data (1994-2014). The stochastic frontier model result revealed that production inputs for producing wheat and barley in the two farming system had significant effect. Cr...

متن کاملIncreasing Crop Diversity Mitigates Weather Variations and Improves Yield Stability
Cropping sequence diversification provides a systems approach to reduce yield variations and improve resilience to multiple environmental stresses. Yield advantages of more diverse crop rotations and their synergistic effects with reduced tillage are well documented, but few studies have quantified the impact of these management practices on yields and their stability when soil moisture is limi...
