摘要

The water hyacinth (Eichhornia crassipes) is an invasive species that rapidly multiplies and leads to the extinction of native species. These intrusions progressively destroy the natural environment of freshwater environments. Managing and controlling these species is difficult, but finding ways to turn this weed into a valuable resource can significantly help tackle this issue. This study focused on generating revenue from the water hyacinth, which is disrupting water bodies worldwide. The study serves as a case study for sustainably managing urban wetlands and water bodies. Satellite imagery from the RESOURCESAT-2 (LISS IV) sensor was used to map the water hyacinth-affected areas in the study location before (May) and after the monsoon (October) seasons. The mapping was carried out using false colour composite and Normalized Difference Vegetation Index (NDVI). Water hyacinth samples were harvested in the pre-monsoon season from five locations, utilizing a 1 × 1 m quadrat. Water hyacinth coverage increased in the pre-monsoon season (27 hectares) compared to the post-monsoon season (14 hectares). The in-situ biomass assessment indicated a 19% reduction, with a green mass of 5.800 kg and a dry mass of 1.102 kg. Our approach to calculate the total revenue generated from the water hyacinth, considering the production of Moorhen yoga mats, has shown promising results. It was assumed that only 50% of the total mass is available, allowing for the production of around 50,000 mats. This could potentially result in domestic revenue of approximately 5.95 crores and international revenue of 7.43 crores. This approach represents a significant advancement in stakeholder engagement within the community, particularly highlighting the contributions of women’s groups engaged in the production of water hyacinth mats and handicrafts. By leveraging these activities, the method not only enhances livelihood opportunities but also ensures sustainable support for indigenous communities over the long term. Eco informed strategies for managing water hyacinth focus on sustainable practices that benefit both ecological health and community needs. The strategies are resource utilization of water hyacinth, Integrated Water Resource Management (IWRM), Sustainable and eco-friendly harvesting techniques, continuous monitoring, and research.
