Soil Microbial Population Dynamics and Shifts in Arid Lands Due to Global Warming
摘要
Soil microorganisms make considerable contributions to soil properties through multiple actions to support plant growth for food securityFood security and are greatly affected by a changing climate. The microorganisms require optimum conditions to thrive and perform their functions including but not necessarily limited to nutrient cyclingNutrient cycling, decomposition of organic matter to compost and organic fertilizers etc. It is not clear how climate changeClimate change (global warming)Global warming is going to impact the dynamics of microbes (risks of extinction or irreversible loss of microorganisms) and impact onArid arid land agricultureAgriculture. In order to fully comprehend and enhance our knowledge of the community composition and functional attributes of soil microbial populationPopulation, it is essential to record changes in their dynamics and functions under global warming scenarios. It is believed that without effective and equitable mitigationMitigation and adaptationAdaptation actions, climate change is likely to increasingly threaten the soil microbiology. Scientists are concerned about the potential shift to soil microbial community structuresCommunity structure and functions where they dwell and how they interact with one another due to long-term environmental changes. However, these conditions and microbial population dynamics may shift when the environment is facing the global warmingGlobal warming condition. In this review, we explored the existing state of knowledge about the impacts of global warming on soil microbiomesSoil microbiome, which already exist under extreme weather-sensitiveArid arid soil environments associating with ecosystem servicesEcosystem services including crop productionCrop production for food securityFood security. The chapter discusses and reviews knowledge in understanding how global warmingGlobal warming may influence biogeochemical cycles by the soil microbiomeSoil microbiome. It also provides insights into the potential ways that soil microbiomes can be utilized to help mitigate the consequences of long-term global warmingGlobal warming through their inputs to soil health and resilience. The book chapter offers valuable insights for researchers and students interested in further understanding in microbial populationPopulation dynamic researchResearch and focus their studies especially on theArid arid region soil microbiomesSoil microbiome with respect to improving arid land agricultureAgriculture productivity for food security.
