Complete the flow chart below to show how prevailing winds bring about such climatic characteristics
in the Sahel.
The Sahel has hot and dry ( onshore /
offshore ) winds in both summer and
winter
In summer,
winds from the south
cannot penetrate inland and lose most of the
when they reach the Sahel
It is ( hot / cold ) and ( wet / dry ) throughout the year in the
Sahel. It has a

2. Based on the information in Table 1 about the climate of the Sahel, are there any physical
farming constraints you can think of?
(*Hint: Think about the temperature and amount of rainfall. Is it favorable for farming? Why or
why not?)
