About this Research Topic
Crop production and food security are seriously threatened by global climatic changes. An increased frequency of heavy rains, floods, and heatwaves is impacting global production and the quality of staple crops and thus, food and nutrition security. For example, climate change is causing ~-1.6 million tons (MT) and ~-5.0 MT annual reduction in global rice and wheat yields, respectively. This translates to a considerable decrease in consumable food calories available from these crops. The challenge of feeding more people in the wake of changing climate is daunting. Innovative strategies that integrate genetic (G) and management (M) strategies for crop adaptation in the changing environments (E) are key, to ensure global food security.
This Research Topic aims to gather original research and review articles on the impacts of current and future climate anomalies on crop yield and quality. Global warming has significantly affected the intensity of climatic variables such as atmospheric CO2 levels, temperature, ground-level ozone, rainfall, fire, and wind. These factors strongly influence crop productivity either directly by interfering with developmental mechanisms of plants or indirectly by increasing competition with insects, weeds, and disease. An understanding of morphological, physiological, and anatomical mechanisms through which crops adapt to extreme climates will assist breeders, selecting crop species resilient to future environments. Further, quantification of the impact of climatic variables on crop productivity will assist crop managers to develop sustainable crop production techniques. Indigenous and potential best management strategies for improving quality and increasing the productivity and resilience of crops will also be documented under this Topic. This will encompass selecting suitable inputs (e.g. right source and rate of varieties and fertilizers), use/application at the correct time, and with the correct method.
Some of the major aspects of this Topic may include, but are not limited to:
● Impacts of current and future climates on crop production systems
● Impacts of climate change anomalies on crop production (quantity enhancement)
● Discussion on the drivers of quality parameters (nutrition/quality improvement)
● Support for crop and land managers, economists, and farmers to select crop varieties and management options better suited to the future extreme climates, thereby offering the best strategies to ensuring food and nutrition security
Reviews, Original Research, Methods, Brief Research Report, Perspective, and Opinion Articles are all welcome for submission.
