Advocacy is the act of supporting or promoting a particular cause or policy, often aimed at influencing decision-makers and public opinion. It plays a crucial role in amplifying the voices of marginalized groups, pushing for social change, and holding governments and organizations accountable. In the context of non-governmental organizations (NGOs) and civil society, advocacy serves as a tool to address various issues, from human rights to environmental protection, by mobilizing public support and leveraging resources effectively.
