This policy brief examines how development actors can support the strengthening of protection systems as low- and middle-income countries move toward a more comprehensive approach to ensure refugees' legal status, socio-economic rights, and access to basic services. Building sufficient capacity to protect refugees requires much more than the creation of legal frameworks or procedures for determining refugees' status, the authors note. Investments in regulations, staff, and infrastructure are also needed. While they have not been traditionally involved with building the capacity of asylum systems, development actors are well-positioned to share their expertise in planning and coordination, public-service delivery, and the promotion of good governance. This expertise could prove an important tool for helping to close the gap in protection system capacity.
