Development of impact functions of global crop yield for climate change policy support models

Principal Component Analysis of Crop Yield Response to Climate Change

Climate variation explains a third of global crop yield variability

Many studies have examined the role of mean climate change in agriculture, but an understanding of the influence of inter-annual climate variations on crop yields in different regions remains elusive. We use detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide. While s...

Farmers’ Perception Regarding Impact of Climate Change on Wheat Crop Production in Layyah District-Pakistan

Pakistan is at 28th amongst the countries that are going to be hurt badly by climate change. It falls in ten major wheat-producing countries of the world in terms of area, production and yield per hectare. Global warming, as a result of climate change, may negatively affect morphological characters of wheat. The present study was undertaken in district Layyah to find out the impact of climate c...

Update on Climate Change and Global Crop Productivity The Influence of Climate Change on Global Crop Productivity

Climate trends over the past few decades have been fairly rapid in many agricultural regions around the world, and increases in atmospheric carbon dioxide (CO2) and ozone (O3) levels have also been ubiquitous. The virtual certainty that climate and CO2 will continue to trend in the future raises many questions related to food security, one of which is whether the aggregate productivity of globa...

The Impact of Climate Change on Grain Yield and Yield Variability in Iran

In this paper, we have examined the effect of climate variables on the yield average and variability of major grain crops (rice, maize, and wheat) in Iran from 1983 to 2014. For this purpose, we made use of the Just and Pope Production Function crop yields panel data. The results revealed that the influences of climate variables were different in the crops. The time trend positively influenced ...
