Drought in wheat – Past and future trends

Understanding how climate is varying and is likely affecting crop productivity in the coming decades is essential for global food security. Climate change studies predict an increase in temperature and more rainfall variability in future decades, …

Do maize models capture the impacts of heat and drought stresses on yield? Using algorithm ensembles to identify successful approaches

Stresses from heat and drought are expected to increasingly suppress crop yields, but the degree to which current models can represent these effects is uncertain. Here we evaluate the algorithms that determine impacts of heat and drought stress on …

Breeding for the future: How to adapt to frost, drought and heat impacts in Australian wheat

While extreme climatic events (frost, heat and drought) can already severely limit wheat production, the expected future increase in extreme temperatures and rainfall variability will further challenge improvement in crop productivity. In addition, …

Projected impacts of climate change on drought stresses in Australian wheat

Wheat is one of the primary staple foods. Due to a rising population and improved living standards, demand for this crop continues to increase. Much of the wheat produced in Australia is grown in water-limited environments. Climate models project …

The shifting influence of drought and heat stress for crops in Northeast Australia

Characterization of drought environment types (ETs) has proven useful for breeding crops for drought-prone regions. Here, we consider how changes in climate and atmospheric carbon dioxide (CO2) concentrations will affect drought ET frequencies in …

Crop design for specific adaptation in variable dryland production environments

Climatic variability in dryland production environments (E) generates variable yield and crop production risks. Optimal combinations of genotype (G) and management (M) depend strongly on E and thus vary among sites and seasons. Traditional crop …

Crop design for specific adaptation in variable dryland production environment

Climatic variability in dryland production environments (E) generates crop production risks. Optimal combinations of genotype (G) and management (M) depend strongly on E and thus vary among sites and seasons. Traditional crop improvement approaches …

Wheat response to drought and heat - Using crop modelling to prepare for the future

While extreme temperature and frequent drought severely affect wheat production, predictions of climate change forecast increased rainfall variability and increased occurrence of high temperature events. Here, we propose modelling tools to predict …
