The latest paper from my PhD is now available online published in the @iwra_water journal #WaterInternational - I have recently seen some great threads describing newly published papers so I am going to give it a go in a few short tweets! (1/8) https://www.tandfonline.com/doi/full/10.1080/02508060.2020.1832747
The paper is titled - "A methodology to identify vulnerable transboundary aquifer hotspots for multi-scale groundwater management". It follows on from my previous research on identifying TBAs in Malawi (2/8)
We used water point and shapefile data to create a hotspot map of transboundary aquifers (TBAs) shared between Malawi and it's neighbours. It purpose was to highlight areas within TBAs that are at risk for reduced water quality and availability (3/8)
Inputted data included hydrogeology, water point type, no. users per water point, proximity of water point to pit latrine, land use and seasonal water availability (4/8)
Results showed that there are 3 TBAs shared by Malawi and neighbours with large hotspots that will need some form of international (gov. to gov.) scale management. 11 other smaller hotspots could be managed at the local scale between neighbouring districts or communities (5/8)
Why is this important? Hotspot maps like this can assist gov. when making decisions about what TBAs to allocate their (often limited) resources to for management. This is particularly vital as we strive towards achieving SDG 6.5.2 (IWRM at all levels including transboundary)(6/8)
Limitations? We only had water point data for the Malawi portions of the TBAs. Expanding the analysis across the border would allow for a more holistic picture. With this map, Malawi can approach its neighbours with a mandate for TBA cooperation and further data collection (7/8)
Thank you! Happy to chat further about my approach and findings if anyone is interested (8/8)
