Improving Crop Resilience in Drought-Prone Agroecosystems: Bioinoculants and Biocontrol Strategies from Climate-Adaptive Microorganisms

Le résumé fourni par la source

Agricultural production is becoming increasingly difficult due to various environmental fluctuations brought on by climate change. Overall increase in atmospheric temperatures due to greenhouse gases, changing rainfall patterns leading to severe water shortages, and deforestation have led to many areas facing drought conditions, causing more stress for producing enough food crops to fulfil increasing global demand. This is also exacerbated by emerging phytopathogens causing severe disease outbreaks, making it difficult to control them without drastic measures. Excessive use of agrochemicals in these areas could lead to more ecological displacements and therefore, sustainable agricultural practices are required to avoid causing more harm. Microorganisms with climate-adaptive characteristics and qualities that would be helpful in acting as bioinoculants and biological control, could prove to be more successful in sustainably controlling emerging pathogens as well as improving the overall plant immunity and health in drought affected areas. We discuss how climate change driven changes in farming areas have made them vulnerable towards emerging pathogens, and highlight how biological control agents can be successfully utilized to possibly overcome this without causing more environmental damage. This review provides a background for future research by linking the climate adaptive characteristics of microorganisms with biocontrol and plant health improving capabilities and how they can effectively be used for eco-friendly agricultural practices in agroecosystems impacted by climate change.
