Understanding the Impact of Drought on Forest Ecosystems: A Comprehensive Review of Physiological Responses and Management Strategies

Astha Singh ^[5] | Dr. K. K. Chandra

Abstract: This review study investigates the possible effects of altered precipitation patterns, particularly drought, on forest ecosystems and emphasizes forests' critical role in the global carbon cycle. It analyses drought stress and how it affects plant development in local and global environments, including tropical forests and India. Review concerns include stomatal conductance, relative water content, electrolyte leakage, and photosynthesis-related to the physiological and biochemical reactions to drought stress. The reported effects on tropical plants are also addressed, with a focus on tree susceptibility and changes in the composition of forests. It describes experimental models for researching drought stress, including soil- and hydroponic-based aqueous culture-based models. The emphasis of the work then switches to the difficulties in forecasting drought community and landscape reaction levels, highlighting the intricate nature of forest ecosystems. Tree mortality is believed to occur during short-term droughts, although long-term trends may favor species that can withstand drought. Strategies for management are discussed, including the use of satellite sensors for surveillance and fire safety. To predict future effects in tropical forest areas, it is critical to comprehend the mechanisms combining hydraulic failure and drought stress. The conclusion emphasizes the necessity of carefully designed experimental programs to improve tolerance to abiotic stressors, particularly drought.
