This Practice Note provides an overview of UNDP’s area-based development (ABD) programming and interventions, tailored for practitioners, policy advisors, and development partners engaged in designing and implementing localized strategies. It highlights the importance of ABD in addressing the distinct challenges of specific geographic areas, particularly in complex, crisis and post-crisis contexts. By prioritizing local ownership, inclusive participation, and flexibility, ABD provides an approach that bridges gaps in service delivery, strengthens resilience, and lays the foundation for long-term development.
