Gender mainstreaming is a strategy for achieving gender equality by ensuring that the concerns, experiences, and needs of both women and men are integrated into the planning, implementation, monitoring, and evaluation of policies, programmes, and projects. It recognizes that social, economic, political, and cultural systems often create unequal opportunities for different genders. In the context of social work and social development, gender mainstreaming seeks to eliminate discrimination and promote equal participation, access to resources, and decision-making opportunities for all genders. Rather than treating gender as a separate issue, it incorporates a gender perspective into every stage of development planning and social welfare interventions. The concept gained global recognition after the Fourth World Conference on Women held in Beijing in 1995, where governments committed themselves to integrating gender perspectives into all public policies and programmes. Gender mainstreaming is based on the principle that sustainable development cannot be achieved unless gender inequalities are addressed. It emphasizes equal rights, social justice, human dignity, and inclusive development. In social work practice, gender mainstreaming plays a significant role in identifying and addressing the different needs of women, men, girls, boys, and gender-diverse individuals. Social workers assess how social norms, cultural traditions, and institutional practices contribute to unequal access to education, healthcare, employment, property, and political participation. They
