Climate Change and Crop Yields in Iran and Other OIC Countries
Climate change is the main phenomenon that directly affects the world environment, and changes in the environment affect economic sectors differently. The most important impacts of climate change would be on enhancing the average global temperature and the decrease in precipitation. The agricultural sector is the first and most affected sector in the climate change. We examined the impact of te...
متن کاملThe Impact of Climate Change on Crop Yields in India
The study of climate change impacts on Indian agriculture has gained recent attention, due to the size of India’s agricultural sector, and reports suggesting that developing countries are more vulnerable to negative climate change effects. Studies in India have focused on predicting future trends using standard climate change scenarios from externally developed models. However, these studies ar...
متن کاملNonlinear temperature effects indicate severe damages to U.S. crop yields under climate change.
The United States produces 41% of the world's corn and 38% of the world's soybeans. These crops comprise two of the four largest sources of caloric energy produced and are thus critical for world food supply. We pair a panel of county-level yields for these two crops, plus cotton (a warmer-weather crop), with a new fine-scale weather dataset that incorporates the whole distribution of temperatu...
متن کاملCoffea arabica yields decline in Tanzania due to climate change: Global implications
Coffee is the world’s most valuable tropical export crop. Recent studies predict severe climate change impacts on Coffea arabica (C. arabica) production. However, quantitative production figures are necessary to provide coffee stakeholders and policy makers with evidence to justify immediate action. Using data from the northern Tanzanian highlands, we demonstrate for the first time that increas...
متن کاملOn Technological Change in Crop Yields
Technological changes in agriculture tend to alter the mass associated with a segment or subpopulation of the yield distribution as opposed to shifting the entire distribution upwards. We propose modeling crop yields using mixtures with embedded trend functions to account for potentially different rates of technological change in different subpopulations of the yield distribution. By doing so w...
