Best practices are those policies that have demonstrated that they produce or are essential to delivering significant quantifiable results. Complementarity, synergies and integration attributes enable an easy fit with other national, regional and international efforts, ensuring ease of implementation and a supportive complementarity with other policies. Political alignment, governance and accountability attributes help ensure policies are politically palatable and are likely to work and persist in multi-layer governance frameworks where national, regional and local governance influence effectiveness of policies and enable outcomes.
