**4. Conclusions**

The wetland ecosystems have vital values and functions in the world. Human (controlling factor), as an ecosystem stakeholder, benefit from this. Rapidly developing technology enables us to better understand the planet we live in. Due to technological development and increasing human population, all ecosystems are inevitably deteriorated by domestic, agricultural, and industrial pollution; climate change; reducing biodiversity; invasive species; and change of land use. Sustainability includes a greater and more explicitly long-term situation and target than environmental quality increment. Sustainable environmental management depends mainly on ecosystem stability, ecologic tolerance, and biotic diversity. Sustainable environmental management plans need to be implemented and controlled.

Therefore, the role of decision-maker authority is important. The fact that the research institutes and the sciences in different disciplines form a consortium and maintain their management plans with a holistic approach has a critical value in this respect. Due to the different kinds of wetlands and the case study of multidisciplinary approaches in the world, the book *Wetlands Management: Assessing Risk and Sustainable Solutions* can be considered as an important source.
