The purpose of the Implementing Agency survey is to assess the role and ‘performance’ of implementing agencies and individual implementers in delivering secure tenure for communities, both men and women, in line with reform expectations. It is concerned with identifying key goals, strategies, and actions related to reform implementation as well as factors enabling or constraining the ability of implementers to achieve related goals. This study attempts to generate insights into the underlying processes and factors that influence tenure reform implementation. In particular, it identifies the factors that enhance or constrain reform implementation from the perspective of individual implementers in government agencies at national and sub-national levels in four countries: Indonesia, Peru, Nepal and Uganda. These four countries introduced reforms in their forestry sectors in the late 1990s; most of these reforms were intended to shift greater rights and responsibilities over forest resources to lower levels of governance including sub-national actors and local communities. The interviews were conducted between July and December 2016, interviewing about 30 respondents in each of the four countries (Indonesia, Uganda, Peru and Nepal).
