I think we need to stop drawing water from under the ground, it is causing some major problems, and increasing desertification. The Chinese are starting to provide desalination plants, and this would seem to be a better solution. It provides a pretty marginal reduction in sea levels, but more importantly, it starts to replace the groundwater, and can lead to reforestation if managed correctly.
This is a great suggestion and environment-friendly, too. This is also what some developed countries are doing such as Singapore. The problem with this is that it costs too much for a charity organization which is highly dependent on donors. For sure, they cannot handle the costs for such an ambitious yet highly preferred option, especially if their target countries are located within the central parts of Africa. It would be impossible. Governments have the resources though to undertake such desalination projects.
I noticed that Bitcoin and crypto is rising as an alternative form of donation for charities such as this. I wish this project the best of success in the future. Africa really needs our care and attention.
