This edited volume provides a review of remediation approaches utilizing aquatic and wetland macrophytes in the Tropics. This form of phytotechnology has exceptional potential as a sustainable nature-based solution, but that potential is not commonly utilized in the Tropics. Constructed wetlands for improvement of water quality are cost-effective, offering affordable solutions for remediation in warm and tropical regions worldwide. The robustness, simplicity, and reliability of treatment wetlands provide efficient long-term operation. Wetlands for Remediation in the Tropics covers theory, provides case studies, and identifies gaps in our current understanding. It highlights why the Tropics differ from temperate regions in this context, particularly concerning differences in climate and species diversity and abundance. Urban, rural, and industrial examples are discussed across 11 chapters. These nature-based solutions, including the concept of ‘Sponge City’, can be applied to tropical areas worldwide and incorporated particularly in highly urbanized regions. The authors, from Argentina, Australia, Brazil, Canada, Colombia, the USA, the Netherlands, Mexico, Pakistan, and Taiwan, all have substantial research experience using wetlands for remediation. The topic of this book is relevant not only to scholars and academics but also to practitioners and government officials from developing countries, where scarce resources and a lack of a qualified workforce are common, but large differences exist in history, culture, regulations, climate, water fluctuations, and vegetation. Although ideas based on experiences from temperate regions can be applied, the Tropics require distinct approaches to developing constructed wetlands for remediation.

This book provides a systematic exposition of the design features of constructed wetlands, and their management (in terms of siting, physical maintenance, and operation). Only very few books (or chapters) have been published on constructed wetlands in tropical conditions and none are current. The selection of plant species, managing their growth and harvesting cycles, and the impact these have on the attenuation of organic and inorganic pollutants, nutrients, and pathogens would be of interest to students and practitioners of the art working under tropical conditions. The potential of constructed wetlands as a low-cost intervention for developing countries in tropical regions that faced water pollution problems, in particular, deserves to be explored systematically.

This book describes how natural or constructed wetlands can be used to reduce pollution of freshwater and coastal ecosystems, while still preserving their biodiversity and ecological functions. Through a series of case histories described in 10 chapters in the monograph, the readers will gain an understanding of the opportunities, as well as the challenges associated with reducing point and non-point source pollution using natural, restored or constructed wetlands. The target audience will be water practitioners involved in projects utilizing integrated watershed management approaches to pollution abatement, as well as researchers who are designing projects focused on this topic.

A variety of professionals from around the world, including site managers, scientists, regulators, and engineers discuss issues related to the remediation of wetlands contamination through both engineered and natural attenuation approaches. Illustrated with b&w photographs and diagrams, the 45 contributions address topics such as using wetlands for wastewater treatment; wetlands design, construction, and operation; and wetlands ecology and restoration.

This edited book presents the first collection of case studies and research projects on the sustainable technology of constructed wetlands for wastewater management under hot and arid climates. It is the first such work that summarizes in a single reference the current international experiences and knowledge on the implementation of this nature-based solution under these diverse and often harsh climatic conditions. It covers the relevant gap in the fragmented and limited literature by providing integrated information and documentation on the feasibility of this green technology. The book presents the treatment efficiency of constructed wetland facilities and the research output from 29 different countries across South America, Africa, Asia and Oceania, while it covers various applications such as domestic and municipal wastewater, various industrial effluents and municipal sludge. Many examples and case studies further demonstrate the potential of this technology to contribute to better address the issues of water scarcity and limited fresh water resources through circular management of treated effluents e.g. reuse in irrigation. It also discusses the various challenges and technical aspects that should be considered in such climates, along with the environmental, financial and social benefits of this technology. This work is a useful handbook and guide for professional engineers, practitioners, academics, researchers, students, and water authorities who wish to get a better understanding and first-hand information on the potential of constructed wetlands for cost-effective and sustainable wastewater management in countries with hot and arid climates.
