No easy fixes: Government workers’ perception of policy (in)coherence in the implementation of the Post-2015 agenda in Mexico

The Paris Agreement, the Sustainable Development Goals, Sendai Framework and New Urban Agenda share a vision of global sustainable development, with several overlapping goals targets. However, these agendas are often treated along sectoral boundaries leading to highly branched implementation. Underusing potential synergies is not only burden for governments due costs redundancies inefficiency but can also hinder collective lead inter-agenda trade-offs. Despite growing attention on policy coherence in research policy, existing literature fails explain why it so hard achieve despite widespread recognition its theoretical value. Based review fieldwork Mexico, our focuses perception people charge operationalizing agendas. We develop typology non-monetary benefits that encompasses alternative scenarios 1) increased implementation Mexico 2) business-as-usual scenario. Results challenge dominant approach binary coherence/incoherence analysis, by identifying perceived incoherence building coherence. They highlight importance overlooked barriers cross-sectoral cross-scalar collaboration driven institutional arrangements work culture. resulting differentiates drivers manifestations (in)coherence from their impacts institutions society. From this, we derive scenario Post-2015 represents net gains society relative losses institutions, once current discounted. process beyond easy fixes, requiring structural change. Otherwise, risk falling into cosmetic level both costly ineffective.
