Here are some of the environmental challenges that Africa is facing at the moment:
1. desertification: larger patches of African land are turning into deserts, which is obviously a huge problem because the vegetation of the continent is changing and disappearing
2. no access to water: many African nations have problems finding water in this arid country, which is a danger to their lives
3. population explosion: there are more and more Africans born, and there are not enough resources to sustain them all
Sequential schemes are used to organize ordered, frequently numerical data, such as the ratio of floor area to lot size or the population density per square mile. Since bright colors are used for lower values and dark colors are used for higher values, changes in color lightness correspond to the transition from low to high.

What is color shading on a map?</h3>
Image enlargement The Discovery Series of maps uses shade and color to indicate how high the ground is above sea level in addition to contour lines. The color becomes darker as the terrain rises higher. The very low ground is colored green, followed by pale yellow, and then roughly three different tones of brown.
The intuitive and easy-to-read nature of the map is ensured by the careful selection of colors. Feature association is the term used to describe this process. Additionally, as many people struggle with color vision, the cartographer must pick hues that are simple for such readers to discern.
