I am doing a literature review on the broad number of issues related to informal settlements and illegal construction in the Global North. I would be grateful for your recommendations on country case studies (including city case studies) in North America (USA, Canada), EU 28 (all countries), East and South East Europe (non EU), Central Asia (Incl. Russian Federation, Ukraine, Moldova, Azerbaijan, Tajikistan, Armenia, Georgia, Kazakhstan, Uzbekistan, Kyrgyzstan, etc.), pan-national and international comparisons, challenges identified, lessons learned.
