APPROACH
MANA are implemented annually across different countries through a replicable model of national and international collaboration. Each edition includes:

• Participatory definition of priority areas with national authorities.
• Mobilization of local and regional mapping communities.
• Remote and in-person technical training in open mapping.
• Quality supervision and validation by experts and partner organizations.
• Strategic use of satellite imagery and open tools.
• Delivery of data ready for integration into public policies.

Institutional and Community Impact

• National institutions incorporate the data into priority programs.
• Technical capacities and networks of young mappers are built across multiple territories.
• Long-term partnerships are consolidated to replicate MANA year after year.
• National and international visibility for mapping communities.
  

LESSONS LEARNED AND NEXT STEPS

Youth and university participation has been key to scaling and sustaining MANA, both in producing cartography and in assuming leadership roles for activity coordination and outreach to sometimes large sub-communities of new mappers.

• Data gaps present an opportunity to integrate citizen science into public policies.
• Validation processes and continuous monitoring need strengthening to ensure effective data use.
• The next step is to institutionalize MANA as part of national disaster risk management strategies; institutions show growing interest and commitment as they see engagement from peer institutions.
