Deepening Democratic and Civic Space Across the MENA Region Strategy 2013 — 2018Jamaity
Democratically elected governments understand the need to liberate and utilize the potential of civil society, this would enhance the chances of successful transitions. If other MENA governments took heed and expanded democratic and civic space without waiting for mass protests to spill over into violence, this would stabilize the region. A lasting solution to chronic instability and skewed development lies in democratic reform with active civic participation.
