NGOs may face challenges such as limited funding, bureaucratic obstacles, political pressure, and difficulties in measuring the impact of their work. They also may face security risks and other dangers when working in conflict zones or in areas with high levels of violence or instability.

NGOs play a vital role in society by addressing social, environmental, and humanitarian issues that may not be addressed by governments or the private sector. They often work to promote human rights, advance sustainable development, and provide critical services to vulnerable communities.

While the terms NGO and non-profit organization are often used interchangeably, an NGO typically focuses on international development and humanitarian work, while a non-profit organization can encompass a wider range of activities, including arts and culture, education, and social services.
