URBANIZING DELTAS Fishing Agriculture

Environment Flood-defense & Water-management

Port-economy Urbanization The delta offers:

• Excellent conditions for fish-/shellfish economy • Excellent conditions for agriculture economy • Excellent conditions for trade-economy (ports) • Largest concentrations of population in urban areas • Attractive environments for leisure and tourism • Extreme vulnerable and dangerous living- conditions • Extreme precious and vulnerable bio-diversity • Propitious conditions for new energy (sun, wind, waves, salt-fresh water transitions) Changing urban economy, patterns & typology +
