"Naturalisation of Humans" refers to the process by which humans adapt to their natural environment, learning to live with its constraints and utilizing its resources in sustainable ways. This process involves a deep understanding of local ecosystems, weather patterns, and geological features.
On the other hand, "Humanisation of Nature" refers to the process by which humans transform the natural environment to meet their needs and desires. This process involves activities such as clearing forests, damming rivers, and building cities.
In short, "Naturalisation of Humans" is about adapting to nature, while "Humanisation of Nature" is about changing it to suit human needs.
