If distinguishing between spatial planning systems and practices, the latter reflect on the continuity and perspective of planning cultures and are concerned with the values, attitudes, mindsets and routines shared by those taking part in concrete planning processes. Some recent studies demonstrated comparative assessment of European spatial planning. Thus, the coexistence of continuity and change, as well as convergence and divergence concerning planning practices, was delineated.

Our purpose is to present and test a typology of land reform theories as a means of understanding and interrogating the motives behind land reform and to better equip land administrators and policymakers to enact land reform programs that are appropriate for their contexts. Here, land reform is understood to include the related concepts of land redistribution, land restitution, land tenure reform and land administration reform. The theory typology thus has application for land restitution programs specifically operating in the global South.

Participatory mapping is a valuable approach for documenting the influence of human activities on species, ecosystems, and ecosystem services, as well as the variability of human activities over space and time. This method is particularly valuable in data-poor systems; however, there has never been a systematic approach for identifying the total number of respondents necessary to map the entire spatial extent of a particular human activity. Here, we develop a new technique for identifying sufficient respondent sample sizes for participatory mapping by adapting species rarefaction curves.
