Since his retirement from the IDF, Arieli has been active in several left-wing organizations working to advance a permanent status agreement with the Palestinians.

He is one of the heads of the Geneva Initiative and a member of the board of the Council for Peace and Security (on its behalf, he appeared before the High Court of Justice under the status of a "friend of the court" in the main petitions that were filed regarding the separation barrier and greatly affected its route) and a senior researcher at the Economic Cooperation Foundation NGO.

He completed his doctorate at the Department of Geography and Environmental Sciences at Haifa University, and his research was devoted to examining the development of Israel's borders in comparison to other conflicts zones in the world.
