The contribution of ecological engineering in designing, building, and operating a new ecosystem is noteworthy. The approach of ecological engineering designs is not as simple as it appears since such designs are proposed to apply to species that are known to evolve within a newly created ecosystem. Although new ecosystems are called by various names such as domestic ecosystems, interface ecosystems, and living machines, they are ultimately the outcome of creative designs incorporated with self‐organized properties of the systems themselves. This approach brings about the selection of species naturally within the framework of ecological engineering designs reflecting the manmade designs through the response of natural choices. This feature makes this field a unique and intellectually motivating branch of applied engineering.

With the aim of solving environmental problems, ecological engineering addresses a subset of issues that have been created anthropogenically and then must be resolved by ecological designs. Among these designs, pollution control or treatment is the most frequent in all environmental areas, where polluted materials are considered resources. The designs are formulated in such a way that pollutants are either stabilized or broken down into useful by‐products with the natural development of the ecosystem, thereby converting the problems into solutions for the successful implementation of ecological engineering principles.

In this chapter, we have discussed hard, soft, and hybrid approaches for improving new or existing infrastructure with modern, complex building models. The primary principles of ecological engineering proposed by Ma [28] were designed to formulate species symbiosis, cycling, and regeneration and harmonize the ecological structure with its function. Later, 12 commandants or guidelines were formulated as principles of ecological engineering. Based on these basic principles, rules of ecotechnology can be derived for proper management of the environment and ecosystem.

The terms ecological engineering and ecotechnology are used interchangeably, although the former defines the creation and restoration of ecosystem while the later describes ecosystem management. Nature represents a self‐organizing, self‐sustaining system up to an exploitation threshold. Thus, any new approach must include a scheme to minimize external influence and also fulfill societal demands. A balance between the natural ecosystem and ecosystem engineering services must be achieved for the vitality of mankind. However, it is vital to identify key conservation priorities and carefully design ecological engineering services with ecological principles and rules to develop and manage structures that effectively enhance industrialization with a reduced impact on the environment.

This chapter discussed in great detail some of the major areas those require the attention of ecological engineering projects for development and restoration. For instance, we have explained coastal development and restoration and proposed ways that ecological engineering could be applied productively to improve the ecological benefits of infrastructure and natural habitat for corals and fishes and also encourage sustainability with the growth of urbanization. A common ecological engineering approach adopted for successful restoration of mangroves practices analytical thought processes with minimum exploitation of the mangrove ecosystem. Various nonstructural measurements are applied in the development of flood hazard plans, including locally grown flood‐fighting crops that help with risk management as well as controlled river engineering by ecological restoration. Likewise, we can rely more on internal regulatory methods rather than traditional agricultural practices.

Soil ecology restoration is the next step toward attaining an overall sustainable agricultural ecosystem. One of the major challenges in the near future is sustaining the human population while maintaining the integrity of the environment. Earth is a closed system, and thus it will be wise to apply human potential toward achieving this goal. Therefore, the expansion of restoration projects in terms of expectations and goals must be realized to achieve all the plausible ecological aspects. Ecological restoration and management should make both explicit and implicit efforts to predict and recommend the ecological future of a location. These attempts need to be extrapolated beyond the prediction within the boundary of scientific limitations during the implementation of ecological restoration and management projects.
