Addressing multiple abiotic stresses through local solutions is essential for food security
摘要
The rapidly growing world population is placing mounting pressure on agricultural systems, making it increasingly challenging to provide food. Climate change has thus emerged as a frontline threat to sustainable food security, intensifying multiple abiotic stresses across agricultural systems. Abiotic stresses seldom appear in isolation; instead, they often interact, both among themselves and with biotic stressors under field conditions. This results in compounded impacts that are difficult to quantify and manage under field conditions. This opinion article highlights the importance of quantifying and managing abiotic stressors under the rapidly changing climate to achieve food security. Here, we provide a brief overview of major abiotic stress types classified as atmospheric, edaphic, and water stresses, and propose a conceptual framework for analysis and decision making. This opinion article argues that localized, context-specific strategies are essential for agricultural adaptation and mitigation, considering the spatiotemporal impacts, magnitude and frequency of stresses, as well as the vulnerability and resilience of the farming system to abiotic stresses. Future research must prioritize the quantification of multiple stressors and the development of integrated stress management strategies. By aligning global agricultural innovation with local needs and sustainability goals, resilient food production systems can be built that may meet the growing world food demand.
