This paper evaluates how land governance is re-arranged in a state re-structuring process. We compare the cases of the (re-)unification of China with Hong Kong with that of West and East Germany. The division and (re-)unification of these states mark different land governance re-arrangements. The China-Hong Kong (re-)unification relied on a one-country two-system (OCTS) approach, while in West and East Germany, (re-)unification resulted in the creation of a one-country one-system (OCOS). Our key interest is to identify similarities and differences in both cases and the implications of the differences. To support the analysis, we view land governance and (re-)unification from theoretical to practical lenses-structuration theory and the government tools-based approach. This supports the construction of a conceptual and analytical framework, with which we conduct an in-depth exploration to evaluate land governance re-arrangements. We find that the conceptual and analytical framework proves effective for countries, with entirely different land governance regimes, to decide whether to merge or adapt. We do not conclude which approaches for (re-)unification are appropriate to land governance re-arrangements since all countries have different historical contexts and institutional arrangements. Instead, we recommend that governments consider adaptive land governance in signification structures and focus on hierarchical enforcement in legitimation structures. While multi-level land governance in the domination structure phase is strongly required, issue-and-project-based land governance has a pivotal role in providing cross-boundary infrastructures. Nevertheless, further empirical analysis is recommended to verify how and where the re-arrangement processes are initiated and structured.The North and South Korean (re-)unification quagmire is not new in the world. There are many divided countries in need of reunification and there are others that were once divided but finally became reunified. Countries like Cyprus (Turkish and Greek Cypriots), Sudan (Sudan and South Sudan), and Yemen (South and North Yemen) are some countries in need of reunification. China, Vietnam and Germany are examples of countries that were once divided and then became reunified.Adm. Sci. 2019, 9, 21 2 of 26 systems differed vis-à-vis the ideological role of the state, this raised challenges during and after the (re-)unification process.Land governance has been critical to this transforming institutional form and function (Augustinus 2009;Borras and Franco 2010;Deininger and Feder 2009;Enemark 2012). According to Palmer et al. (2009), land governance ruminates more intensely on the matter of the rules, processes and structures about land and its use and concern about who made decisions and how implemented and enforced. As the product of open-ended interactions within structures and agency, land governance can differ significantly depending on the state structures (e.g., unitary state; federal state) and the (re-)unification mechanisms (e.g., civilizat...
