The soil-water-plant-atmosphere system (SWPAS) is a “physically integrated, dynamic system in which interacting processes of mass and energy are performed.” The SWPAS system is comprised of four different components with varying physical and chemical properties that ultimately poses a complex mechanism. Water stress is primarily caused due to nonuniform precipitation. The exhaustion of this reservoir by a crop requires its artificial reloading, which is the case of irrigation. Soil moisture has been shown to have major implications for carbon storage and related climatic feedbacks. Therefore, it is more important than ever to understand how the flow of water interacts with ecosystem health and the mechanisms controlling water fluxes at the land-atmosphere interface. Atmosphere acts as an upper buffer that takes up, transforms, and protects water, as a substance, in the climatic system. The soil-plant-atmosphere continuum (SPAC) is the pathway for water moving from soil through plants to the atmosphere. Movement of water occurs in response to differences in the potential energy of water. The flow path of water through SPAC is complex with a series of resistances offered by different components of the system. Different atmospheric, plant canopy, and soil factors affect the water flow through SPAC. With increasing water scarcity, improvement in crop water productivity will be vital in terms of food security for the future generation. As a result, the effect of soil-plant-atmosphere interactions on how ecosystems respond to and exert influence on, the global environment remains difficult to predict. © 2022 Elsevier Inc.

Climate is a major factor that governs several things starting from the origin of the different animals, and food availability for human and animals. The growth of crops species is becoming more vulnerable due to the climate now. The living ecosystem of every creature depends on the climate. Climate change is the prime threat to the sustainability of our ecosystem and continuous emission of the greenhouse gases is making it more perilous. As a consequence, an unanticipated shift in the dynamics of plant-soil cross-talk is encountered. Nevertheless, gradual escalation of mean earth surface temperature can potentially curtail the duration of the growth period, yield, and water productivity. Every major crop are expected to decline due to erratic precipitation and higher water demands under elevated temperature. In this chapter, we mainly highlight the impact of fluctuating climatic elements on terrestrial flora, edaphic conditions, and their mutual interactions. Surging air temperature is detrimental for the soil carbon stock and its depletion hampers the rhizospheric processes, biochemical cycles, and ultimately affects plant species. We have also discussed different processes involved in plant-soil interactions at different stages of primary or secondary succession. © 2021 Elsevier Inc. All rights reserved.
