Brief Explanations:

One environmental challenge is desertification. In Africa, over - grazing, deforestation and climate change are causing fertile land to turn into desert, reducing arable land for agriculture and leading to food insecurity. Another is water scarcity. Many parts of Africa have limited water resources due to uneven rainfall distribution and pollution of existing water sources. Water scarcity affects drinking water supply, agriculture and industrial activities. Desertification may need more immediate attention as it has a cascading effect on other aspects like water availability, food production and biodiversity loss. It can displace communities and lead to social unrest.

Answer:

Two environmental challenges are desertification and water scarcity. Desertification may need more immediate attention due to its wide - ranging and cascading negative impacts.
