Governance aspects must also be understood in order to fully grasp the myriad of uncertainties, difficulties and opportunities that arise in managing water, energy and land resources, in making efforts to protect the environment, and eventually in the course of implementing solutions. The TBNA methodology has incorporated this kind of thinking from its inception and was thus developed as a two-track approach, with the two tracks being fully complementary. In addition, the fourth step explores the salient characteristics of an institutional framework by considering four variables of the governance system, namely: extent, coherence, robustness, and flexibility. The focus of the analysis is on policy coherence, as well as on identifying overlaps, gaps and complementarities of responsibility.
