“…In recent years, scientists have learnt that terrestrial ecosystems' vegetation, soil [28,29], and animals [30,31] play key roles in mediating the C-cycle. Vegetation being the primary producer, it is from the plants whose mass and energy get transformed to other living beings, within an ecosystem [32]. The process of photosynthesis fixes atmospheric C into the biosphere.…”

The terrestrial carbon (C) cycle has a great role in influencing the climate with complex interactions that are spatially and temporally variable and scale-related. Hence, it is essential that we fully understand the scale-specific complexities of the terrestrial C-cycle towards (1) strategic design of monitoring and experimental initiatives and (2) also developing conceptualizations for modeling purposes. These complexities arise due to the nonlinear interactions of various components that govern the fluxes of mass and energy across the soil-plant-atmospheric continuum. Considering the critical role played by hydrological processes in governing the biogeochemical and plant physiological processes, a coupled representation of these three components (collectively referred to as ecohydrological approach) is critical to explain the complexity in the terrestrial C-cycling processes. In this regard, we synthesize the research works conducted in this broad area and bring them to a common platform with an ecohydrological spirit. This could aid in the development of novel concepts of nonlinear ecohydrological interactions and thereby help reduce the current uncertainties in the terrestrial C-cycling process. The usefulness of spatially explicit and process-based ecohydrological models that have tight coupling between hydrological, ecophysiological, and biogeochemical processes is also discussed.

“…Engineers may be perfectly capable of working out a basic physical design or the hydro-geomorphology for what may seem an appropriate solution to a problem of the environment, but may ultimately not provide a successful solution because the scale or complexity of the problem was not adequately predicted and analyzed. The complexity and scale of biological systems [20] make it difficult, sometimes impossible, to understand how these systems behave at different levels of organization from elemental cycles to community metabolisms, and how these levels interact. Moreover, biological systems and components [21] take different and variable times to respond to engineering solutions or to changes in general.…”

Abstract:The impact of human activity on the biosphere has produced a global society context in which scarcity of natural resources and risks to ecological health such as air pollution and water contamination call for new solutions that help sustain the development of human society and all life on earth. This review article begins by recalling the historical and philosophical context from which contemporary environmental engineering has arisen as a science and domain of technological development. Examples that deal with some of the core issues and challenges currently faced by the field, such as problems of scale and complexity, are then discussed. It is emphasized that the sustainability of the built environment depends on innovative architecture and building designs for optimal use and recycling of resources. To evaluate problems related to global climate change, storms, floods, earthquakes, landslides and other environmental risks, the behaviour of the natural environment needs to be taken into account. Understanding the complex interactions between the built environment and the natural environment is essential in promoting the economic use of energy and waste reduction. Finally, the key role of environmental engineering within models of sustainable economic development is brought forward.
