Answer:
Some of the dangers a farmer might face are drought or flooding....
Drought is a main problem in the middle east. Drought has always been a problem in the middle east because it could result in big problems when you grow your crops. A way to prevent this problem would be having a big storage and supply of water to help the crops.
Flooding is the opposite of drought....A lot of water can destroy every single crop because of it's enormous non-stoping supply of water and rainfalls. In this situation, channels would be really useful so that the water can flow and not damage the crops, it would go back to the lake or ocean.
Hope this helps!!! :)
