Weed Competition under drought conditions in a changing climate.

Agriculture is the most affected sector by climate change since its development is closely related to natural resources use. For this reason, it is affected by variations in temperature and rainfall. Climate change could further undermine efforts to mobilize water resources for agriculture, due to reductions observed in precipitation at the lowest tropical latitudes. A clear vision of the impact of climate change on weed management in a hot-arid environment is crucial to understand the vulnerability of crop yield in the Mediterranean region. Water resource amounts in many regions of the world, and water availability between crops can be inadequate in areas where natural rainfall is deficient. The research related to interactions between rising carbon dioxide and other anticipated environmental changes is mostly unknown. This commentary has presented a clear and broad discussion of the most recent opinions on this topic. Particularly in the Mediterranean region, knowledge of these potential interactions may be crucial in safeguarding weed threats or production losses in irrigated agriculture.
