Description Water hyacinth (Pontederia crassipes, also referred to as Eicchornia crassipes) is one
of the most invasive weed species in the world, causing significant adverse economic
and ecological impacts, particularly in tropical and sub-tropical regions. Large scale
real-time monitoring of areas of chronic infestation is critical to formulate effective control
strategies for this fast spreading weed species. Assessment of revenue generation
potential of the harvested water hyacinth biomass also requires enhanced understanding
to estimate the biomass yield potential for a given water body. Modern remote sensing
technologies can greatly enhance our capacity to understand, monitor, and estimate
water hyacinth infestation within inland as well as coastal freshwater bodies. Readily
available satellite imagery with high spectral, temporal, and spatial resolution, along
with conventional and modern machine learning techniques for automated image
analysis, can enable discrimination of water hyacinth infestation from other floating or
submerged vegetation. Remote sensing can potentially be complemented with an array
of other technology-based methods, including aerial surveys, ground-level sensors, and
citizen science, to provide comprehensive, timely, and accurate monitoring. This review
discusses the latest developments in the use of remote sensing and other technologies
to monitor water hyacinth infestation, and proposes a novel, multi-modal approach that
combines the strengths of the different methods.
