The role of wetlands in environmental management is integrated with human welfare, agriculture, water quality protection, and pollution prevention. Wetland habitats are globally distributed and commonly regarded as a nuisance, nevertheless, analysis of their ecological structure might support beneficial merit to human society. Improvement of pollutant removal and creation of land use usage aimed at nature protection, food production, or removal of environmental pollutants is critical. The control of the water balance, plant management, and the efficient and renovated management of wetlands are hot topics of the proposed book entitled " Wetland Ecosystems - Structure, Management, Human Welfare Support, and Land-Use Efficiency". A vast number of studies were published due to the common interest in this topic. Therefore, the time has come to assemble recent information into a book. This book might be an appropriate document for modern studies to be presented. The relevance of such a book includes also global trends of climate change and water scarcity as well as the expansion of land productivity reduction.
