This work tells us about the dynamics of the proliferation of invasive plants in the riverbed in the District of Bamako (Mali). The study aims to analyze the spatio-temporal dynamics of EABs in the Niger River bed at Bamako level between 2000 and 2018. The study also aims to assess the impact of VAE on river flow from 2000 to 2018. The methodological approach relies essentially on remote sensing through the acquisition of Landsat ETM+ and OLI satellite images via "earthexplorer.usgs.gov" and their processing for cartographic rendering. Based on a multi-date diachronic analysis, the study shows that the dynamics of VAE proliferation on the river are contrasted from one year to the next. Over the period 2000 - 2018, the study shows a decrease in VAE from March to September, but also inter-annual growth, with a spatial expansion rate of 15.50%.

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
