Climate change and weed management in Australian farming systems

摘要

Each year the level of uncertainty surrounding the evidence for a warming world and human influence on some of this warming seems to decrease amongst climate scientists and more recently, agricultural scientists and farmers. However, there will alwaysbe significant uncertainty on how increasing CO: and global warming will be translated to changes to regional climate and how these changes will influence weed management in agricultural systems in Australia. Weed management R&D and the practice of weedmanagement needs to take into account worrying but uncertain projections from climate science. There is a significant challenge in trying to understand the impacts and complex interactions of climate change on crops, weeds and management options. We also need to take an adaptive management approach and build resilience. We suggest that increasing CO, and temperature will enhance weed problems and conclude that sound weed management is one of the best ways that Australian farmers can build resilience and reduce their vulnerability to climate change.
