This area is called "Fushqa" (Arabic: فشقة), it’s a border area between Sudan and Ethiopia which was disputed, now it belongs to Sudan.
The structured area you see is a "modern" village, built by the government of Sudan for the local farmers to encourage them to stay since the land is fertile and being a disputed land with a few attacks from Ethiopian militias people needed a good reason to feel safe and stay, building these villages provide some sort of security better than having them scattered around a huge area with no facilities.
