In the recent past, humanitarian actors have made remarkable progress towards the inclusion of at-risk populations. Nonetheless, providing responses that are adapted to the specific needs of these populations still seems a complex and costly challenge for many. The solution lies in adopting simple and coordinated approaches among different actors that encompass the full range of needs. Therefore, intentional actions and steps must be taken to identify and reduce the risks and vulnerabilities of those who are most in danger of exclusion and marginalisation. This can be achieved by leveraging locally available resources, including human and financial resources, robust data collection and analyses, meaningful participation, inclusive budgeting, and close monitoring. This chapter offers an opportunity to learn about the concepts, frameworks, approaches, and tools for age, gender, and disability inclusion in humanitarian action. It provides an overview of common and widely tested approaches.
