Capacity building refers to the process of strengthening and developing an individual or organization's ability to perform a specific function or fulfill a particular role. This can involve improving skills, knowledge, systems, structures, and resources that are necessary for effective performance. Capacity building is often used in the context of international development, where it refers to efforts to improve the capacity of governments, organizations, and communities to address challenges such as poverty reduction, healthcare, education, and economic growth. The goal of capacity building is to empower individuals and organizations with the tools they need to succeed on their own, ultimately leading to sustainable development and long-term progress.
