An urgent need for people of the sahel is

becoming self-sufficient
preserving fishing territories
building fighting forces
developing heavy industry

I think the correct answer from the choices listed above is the first option. An urgent need for people of the Sahel is becoming self-sufficient. The semiarid steppes of the Sahel have natural pasture, with low-growing grass and tall, herbaceous perennials. Hope this answers the question. Have a nice day.
