Environmental, Economic, and Social Potentialities of Ornamental Vegetation Cultivated in Constructed Wetlands of Mexico

Sustainable development implies the proper use of natural resources, such as water resources, but the environmental, economic, and social benefits should also be considered. In the water sector, for example, sanitation is one of the challenges that arise in rural localities. However, issues related to it may be solved with the use of constructed wetlands (CWs), which may allow the cultivation of ornamental plants with phytoremediation properties. Through a content analysis, the environmental, economic, and social potential of ornamental species used in Mexico for phytoremediation in CWs is documented in this study. The environmental potential of the plants was considered based on their phytoremediation properties. The economic potential was determined from research articles and from the National Agri-Food Information System. The social potential was analyzed considering the ornamental and artisanal use of the plants. In total, 21 species of phytoremediation plants were identified. Anthurium andreanum and Zantedeschia aethiopica stand out for their commercial value, reported in 2018 to be 272,875 and 30,318 USD, respectively, at the national level. The social potential was identified by the ornamental or artisanal use for flower arrangements and weaving. This study reveals that the use of CWs with ornamental vegetation is a sustainable option to clean wastewater, reuse water, and generate economic incentives. Thus, it is essential to provide the community with adequate training for the management of CWs in those sites that lack treatment systems.
