Ensemble yield simulations: crop and climate uncertainties, sensitivity to temperature and genotypic adaptation to climate change
Estimates of the response of crops to climate change rarely quantify the uncertainty inherent in the simulation of both climate and crops. We present a crop simulation ensemble for a location in India, perturbing the response of both crop and climate under both baseline (12 720 simulations) and doubled-CO2 (171 720 simulations) climates. Some simulations used parameter values representing genot...
متن کاملClimate Change, Crop Yields, and Undernutrition: Development of a Model to Quantify the Impact of Climate Scenarios on Child Undernutrition
BACKGROUND Global climate change is anticipated to reduce future cereal yields and threaten food security, thus potentially increasing the risk of undernutrition. The causation of undernutrition is complex, and there is a need to develop models that better quantify the potential impacts of climate change on population health. OBJECTIVES We developed a model for estimating future undernutritio...
متن کاملCrop and pasture response to climate change.
We review recent research of importance to understanding crop and pasture plant species response to climate change. Topics include plant response to elevated CO(2) concentration, interactions with climate change variables and air pollutants, impacts of increased climate variability and frequency of extreme events, the role of weeds and pests, disease and animal health, issues in biodiversity, a...
متن کاملNew climate change scenarios
whaling in the Southern Ocean is problematic. " The Japanese are still out catching fairly significant numbers of whales, and not just minkes, though that's what they're meant to be focusing on, " he commented. " If they stuck to their targets, and did their whaling as they say they do when they're at the IWC meetings, then I think they might have a little more support. They'd also need to do t...
متن کاملClimate change in Central America and Mexico: regional climate model validation and climate change projections
Central America has high biodiversity, it harbors high-value ecosystems and it’s important to provide regional climate change information to assist in adaptation and mitigation work in the region. Here we study climate change projections for Central America and Mexico using a regional climate model. The model evaluation shows its success in simulating spatial and temporal variability of tempera...
