This lecture explores how drought stress influences the emergence, severity, and spread of forest diseases. It explains the physiological impacts of water scarcity on trees, how weakened hosts become more susceptible to pathogens, and how drought can enhance the aggressiveness or spread of certain fungi and pests. The session also highlights interactions between climate change, prolonged dry periods, and increased disease pressure on forest ecosystems, emphasizing the need for adaptive forest management strategies.
Keywords: Drought stress, Forest diseases, Tree physiology, Climate change, Pathogen susceptibility
