There is no single official ranking of countries that "need volunteers the most." Humanitarian and development needs change according to conflicts, natural disasters, displacement, poverty, health emergencies and available resources.
However, countries experiencing major humanitarian or development challenges can have particularly strong demand for qualified volunteers.
The United Nations Volunteers (UNV) programme works across development, peace and security and humanitarian contexts. In 2025, more than 17,000 UN Volunteers were deployed in 172 countries, demonstrating the global scale of the programme.
Volunteer demand can be particularly important in countries affected by:
Armed conflict
Refugee and displacement crises
Natural disasters
Food insecurity
Public-health emergencies
Poverty
Climate-related challenges
Weak infrastructure
Limited access to education
Governance and institutional challenges
Rather than choosing a country solely because it appears on a "most needed" list, prospective volunteers should examine current assignments published by UNV and other reputable organizations.
Yes.
African countries host many UN development and humanitarian programmes, and UNV reports strong demand for national volunteers and a wide range of professional roles.
However, the need varies considerably between countries and even between regions within the same country.
Volunteer opportunities can involve health, education, project management, communications, engineering, logistics, agriculture, environmental programmes, governance and community development.
Yes.
Countries hosting large refugee populations can require support in areas such as protection, community outreach, education, health, livelihoods, logistics and programme management.
UNV's high-demand profiles include areas such as protection, refugee status determination, resettlement and reintegration, project management, public information, engineering and health.
Yes.
Online volunteering has become an important way to contribute without relocating.
UNV's Online Volunteering Service connects volunteers with organizations working on development and humanitarian objectives. Demand has grown significantly; UNV reported requests for more than 32,500 online volunteers in 2025.
Online assignments can involve research, translation, communications, graphic design, data work, technology and other skills.
Not simply because the need is high.
Humanitarian environments can involve significant security and health risks. Professional UN assignments in difficult locations generally have specific selection, preparation and duty-of-care arrangements.
Someone looking for their first volunteer experience may be better suited to a local, national or online assignment.
UNV identifies several areas where international volunteers are frequently needed, including:
Development and project management
Legal affairs
Political affairs
Public information
Engineering
Health
Monitoring and evaluation
ICT
Logistics
Procurement
English is frequently required for international assignments, while additional languages can be important depending on the location.
The most reliable approach is to use the UNV Unified Volunteering Platform.
UNV states that candidates need to create a profile in its Global Talent Pool before applying for volunteer assignments. Some candidates can also be matched directly from the talent pool.
There is no permanent list of countries that need volunteers the most. Humanitarian needs change continuously. Countries affected by conflict, displacement, disasters, poverty and development challenges can have significant demand, but the best approach is to examine current UNV assignments and the skills requested for each opportunity.
