This knowledge product is part of the work undertaken by the Bank in the context of its new Strategy 2013-2022, whose twin objectives are “inclusive and increasingly green growth”. Following a request from the Sierra Leonean authorities, this document was designed to assist government officials and national stakeholders to consider key challenges and identify major opportunities for mainstreaming inclusive green growth into the 2013–2018 Poverty Reduction Strategy Paper, known as the “Agenda for Prosperity”. The document has been prepared in consultation with the Sierra Leonean stakeholders. The main document is structured as follows: Section 1 outlines principles of green growth with relevance to the specific context of Sierra Leone. Section 2 outlines the main development opportunities and challenges of Sierra Leone, structured along the three green growth pillars the country has identified. Section 3 outlines institutional and policy challenges, as well as a possible framework for green growth. Section 4 summarizes development priorities identified in the A4P, and identifies green growth options in the A4P pillars. Section 5 provides recommendations for efficient implementation.
