“…Multispectral remote sensing is used to monitor water bodies, and maps can be drawn in many ways, and this depends on the response of water bodies to those different spectral ranges. The natural difference water index (NDWI) is used to measure the area of water bodies through short-wave infrared and visible green light [18].…”

Sawa Lake is one of the unique lakes in Iraq. It is located in the southwestern part of Iraq. It is one of the closed lakes, as no surface water source works to feed the lake. The lake feeds on groundwater. The source of this groundwater is the Dammam Basin. During the past ten years, The lake has had many changes, which led to a decrease in water levels. This also led attention to study of the causes of these changes. Many types of research were presented in the study of the state of the lake. This research used remote sensing images from Landsat 8 OLI to monitor the changes during 2020-2021 by applying the NDWI equation to extract water area from image data. The results of the areas were obtained from a special report by Normalized Difference Water Index (NDWI). Then, the lake surface water temperature was derived from Landsat 8 thermal bands (TIRS). The lake water area and temperatures increased in summer and decreased in winter and autumn. Then, it is not the main reason for the change in the lake water area. The levels of the lake water rise during the dry period and decrease during the rainy period. The natural factors have little influence in reducing the lake water. It is attributed to human factors, groundwater depletion, and a reduction in water supply from the Dammam Basin, which feeds the lake.

As an invasive species, water hyacinths (Eichhornia crassipes) are known to progressively proliferate and cause the ecological invasions of aquatic environment. Their incursions not only cause the disappearance of native species but gradually degrades the natural habitats of freshwater regimes.The control and management of these species is laborious task, however, transforming weed into wealth can substantially serve a sustainable approach to reduce the efforts. Therefore, the present study intends to utilise the application of geospatial techniques for mapping the water hyacinths growth in the Deepor beel (wetland) of Assam, India. Sentinel based image analysis has shown that pre-monsoon seasons has encountered massive productivity and area coverage of water hyacinth, whereas in post-monsoon seasons, productivity of water hyacinths reduces to half. Furthermore, insitu biomass estimation of the water hyacinths samples same around the productive season has been collected and analysed 6 kg (green biomass) and 1 kg (dry biomass after sun-dried). Finally, this hybrid approach evaluated the production and revenue generation from Moorhen yoga mat (handicraft item) made from the dried water hyacinths. After assuming the actual availability of 50% of total mass yield of water hyacinths, around ~ 0.8 million (8.8 lakhs) yoga mats can be commercially produced within the most productive seasons. The revenue generation from the yoga mat in the domestic and international markets evaluated around US $ 12.79 million (Rs. 105.85 Crore) and US $ 15.99 million (Rs. 132.31 crore), respectively from a single productive season. Thus, applicative intent of this study can boost potential market in Assam, renovate the weed waste of water hyacinth into wealth generation, and sustainably support the livelihoods of the local communities.
