This document provides a partnership framework for UNCDF’s Last Mile Finance Trust Fund (LMF TF). Through this new Trust Fund (TF), UNCDF will support the Least Developed Countries (LDCs) in their pursuit for sustainable development through innovative finance and business models that have truly transformative impact on peoples’ lives. UNCDF will bring together a group of partners to support sustainable development in the “last mile” areas of LDCs, where resources are scarcest and the development challenges for underserved populations the greatest. This TF will focus on thematic areas of critical importance for the realization of the new 2030 Agenda in the LDCs. These areas are also crucial to laying the groundwork for structural transformation at the local level that will help LDCs meet their graduation ambitions, as emphasised in the Istanbul Programme of Action 2011-2020.
