Integrating pests and pathogens into the climate change/food security debate
TLDR
More mechanistic inclusion of pests and pathogen effects in crop models would lead to more realistic predictions of crop production on a regional scale and thereby assist in the development of more robust regional food security policies.Abstract:
While many studies have demonstrated the sensitivities of plants and of crop yield to a changing climate, a major challenge for the agricultural research community is to relate these findings to the broader societal concern with food security. This paper reviews the direct effects of climate on both crop growth and yield and on plant pests and pathogens and the interactions that may occur between crops, pests, and pathogens under changed climate. Finally, we consider the contribution that better understanding of the roles of pests and pathogens in crop production systems might make to enhanced food security. Evidence for the measured climate change on crops and their associated pests and pathogens is starting to be documented. Globally atmospheric [CO(2)] has increased, and in northern latitudes mean temperature at many locations has increased by about 1.0-1.4 degrees C with accompanying changes in pest and pathogen incidence and to farming practices. Many pests and pathogens exhibit considerable capacity for generating, recombining, and selecting fit combinations of variants in key pathogenicity, fitness, and aggressiveness traits that there is little doubt that any new opportunities resulting from climate change will be exploited by them. However, the interactions between crops and pests and pathogens are complex and poorly understood in the context of climate change. More mechanistic inclusion of pests and pathogen effects in crop models would lead to more realistic predictions of crop production on a regional scale and thereby assist in the development of more robust regional food security policies.read more

Testing and modelling the effects of climate on the incidence of the emergent nut rot agent of chestnut Gnomoniopsis castanea
TL;DR: A relationship between climate and incidence of G. castanea is supported, providing statistical tools to forecast disease incidence at site level and suggests that the disease is influenced by site-dependent factors whose scale is consistent with the climate variability throughout the sampling region.

Impact of Climate Change Effects on Contamination of Cereal Grains with Deoxynivalenol
TL;DR: This study illustrated the relevance of using quantitative models to estimate the impacts of climate change effects on food safety, and of considering both direct and indirect effects when assessing climate change impacts on crops and related food safety hazards.

Above-Belowground Herbivore Interactions in Mixed Plant Communities Are Influenced by Altered Precipitation Patterns.
TL;DR: This study demonstrates how predicted changes to precipitation patterns and indirect interactions between herbivores can alter the outcome of competition between N-fixing legumes and non-N- fixing grasses, with important implications for plant community structure and productivity.

Evidence that elevated CO2 reduces resistance to the European large raspberry aphid in some raspberry cultivars
P Martin,Scott N. Johnson +1 more
TL;DR: Aphid performance on plants containing the A1 gene grown at e CO2 was similar to that of aphids reared on entirely susceptible plants under either CO2 treatment, suggesting that plants with this resistance gene remained resistant to aphids at eCO2.

TL;DR: Prime horticultural production areas in Europe, the northeastern United States, and southeastern Canada are at greatest risk from H. halys under both current and possible future climates.
