Agricultura andFood Security Challenges

Agricultura is highly sensitivy to temperatur extremes, and heat waves can severely distormit crop develoment andd yield. Heat stress during critival growth fazes - such as flowering andd grain filliing - reduces productivity andd quality. The 2010 Russian heat wave, for example, caused a broughly 30% decline in wheat production, driving global food prices upward and affecting food sequicity worldwide.

As heat waves introducte new agricultural zone, including the grain- producing regions of North America andd Europe, the risk of crop failures and food shortages intensifies. In addition to direct heat damage, progress evaporation rates lead to soil hydromation and water scarcity, further stressing irrigation- dependient farming systems.
