Some of the people are adversely affected (or about to be affected) by a humanitarian or development project, which raises grievances and dissatisfaction about actual or perceived impacts in order to find a satisfactory solution. These grievances, influenced by their physical, situational and social losses can emerge at different stages of project life cycle from designing, implementation and operation of project facility. Not only should affected persons (APs) be able to raise their grievances and be given an adequate hearing, but also satisfactory solutions should be found that mutually benefit both the APs and the project/ ACDO. It is equally important that APs have access to legitimate, reliable, transparent, and efficient institutional mechanisms that are responsive to their complaints. Grievance redress mechanisms (GRMs) are institutions, instruments, methods, and processes by which a resolution to a grievance is sought and provided. Grievance Redress Mechanisms (GRMs) are critical tools for promoting transparency and accountability, reducing corruption, improving service delivery and enhancing overall project effectiveness in interventions and programs. It set processes and tools for social accountability, acceptance and take concerns to remedy the harm posed by the development interventions. A number of mechanisms are available to aggrieved parties to access redress. They can be complex and diverse, internal and external. A formal grievance redress mechanism (GRM) is a system by which queries or clarifications about the project are responded to, problems with implementation are resolved, and complaints and grievances are addressed efficiently and effectively.
