BUILD BACK BETTER THE SELF-MADE CITIES

18 - 22 June 2025, Athens & Santorini, Greece

Actions for formalizing Informal Constructions & Improving the Geospatial Ecosystems, Land Tools & Land Policies

See conference information in Flyer (PDF)

This joint conference continues the ongoing United Nations Economic Commission for Europe & International Federation of Surveyors research that started in 2007 on informal construction and the formalization of the self-made cities in the UNECE region.

These "self-made cities" are rapidly developing urban areas with formal and informal constructions that often lack titling and/or compliance with regulations. Such areas face challenges like limited services, increased disaster risks, unregistered constructions and residents, incomplete cadastral records and missing geospatial information, informal property markets, and an unregulated economy

Through the collaboration among UNECE Working Party on Land Administration, Real Estate Market Advisory Group, European Group of Surveyors, FIG Commission 3 on Spatial Information Management & FIG Commission 9 on Valuation and the Management of Real Estate, and World Bank experts, an international discussion and development forum we will promote professional practice and standards in the field of land administration and management, geospatial ecosystems and valuation/appraisal of real estate and will promote professional expertise

Instructions for submission

 Abstracts should be about 400- 500 words & informative (e.g., including objectives, methodology & main results) 

Following the conference selected papers will be published in a special issue of the Survey Review Journal. This  is optional. Those authors who wish their papers to go through the peer review process, and be published in this special issue, are advised to check Survey Review  

Main groups of topics of interest include

• Formalization of informal constructions projects in the various UNECE member states
  (statistics, strategies & policies, legal frameworks, demolitions, resettlements, monitoring
  of progress, challenges and opportunities)
• Implementation of Local Disaster Risk Reduction & Recovery Plans (earthquakes, flooding, fires), infrastructure provision, Examples of good practice
• Improving the geospatial ecosystems & land tools (land administration, land use, planning/permitting, expropriation & taxation, land consolidation and land readjustment, affordable housing), regulations, procedures, accountability & legislation

Geospatial Technologies & Urban Resilience

• Utilizing low-cost solutions and geospatial tools (e.g., VGI, AI, drones, BIM, IoT) to formalize and improve cadaster and property records and urban management in formal or informal settlements
• Enhancing spatial data integration for urban resilience, disaster risk reduction, and secure geospatial systems to balance open data sharing with cybersecurity
• Community-driven approaches using crowdsourced geospatial data and participatory design to involve local communities in formalization efforts & other land management projects
• Case studies on spatial information management, addressing local challenges in informal settlements and evolving urban areas

Transparency & Data Management in Real Estate

• Formalization of sales and rental markets. Improving real estate market transparency through standardized data collection, valuation, taxation, and professional capacity building
• Evaluating centralized vs. decentralized databases for geodata, ownership, and transaction prices, balancing accessibility and security
• Assessing AI applications in real estate for valuation, market monitoring, and integrating crowdsourcing for reliable property data
• Analyzing property values & climate change impacts, exploring their role in urban planning, financing, and affordable housing solutions
