International sustainability objectives for land use, designated in the Sustainable Development Goals (SDGs) and Habitat III are formulated in general ways. The objectives need specification and regionalisation to raise impact. How far the general spirit of the objectives is reflected in regional and local practiceswill be discussed using the example of the annual scientific meeting of the German Academy of Spatial Research and Planning (ARL). This article shows that discussions about implementation comprise a richness of ideas in good practice and concepts for inner city development in some locations, whereas other disputes, for example, urban-rural interconnections, are missing.

Coastal areas are particularly sensitive because they are complex, and related land use conflicts are more intense than those in noncoastal areas. In addition to representing a unique encounter of natural and socioeconomic factors, coastal areas have become paradigms of progressive urbanisation and economic development. Our study of the infrastructural mega project of Patimban Seaport in Indonesia explores the factors driving land use changes and the subsequent land use conflicts emerging from large-scale land transformation in the course of seaport development and mega project governance. We utilised interviews and questionnaires to investigate institutional aspects and conflict drivers. Specifically, we retrace and investigate the mechanisms guiding how mega project governance, land use planning, and actual land use interact. Therefore, we observe and analyse where land use conflicts emerge and the roles that a lack of stakeholder interest involvement and tenure-responsive planning take in this process. Our findings reflect how mismanagement and inadequate planning processes lead to market failure, land abandonment and dereliction and how they overburden local communities with the costs of mega projects. Enforcing a stronger coherence between land use planning, participation and land tenure within the land governance process in coastal land use development at all levels and raising the capacity of stakeholders to interfere with governance and planning processes will reduce conflicts and lead to sustainable coastal development in Indonesia.

In May 2014, Serbia was hit by a catastrophic flooding event. The Municipality of Obrenovac suffered severe consequences due to a number of reasons, mainly the poor conditions of flood protection infrastructure and outdated land use management. These problems have been triggered and/or affected by the post-socialist transition of Serbia, initiated during the 1990s. The ongoing period of socio-economic turbulences, also detected in other countries with a similar development background, caused a shift in both the planning paradigm and the economy (from a planned/centralized model to a market-oriented model), creating numerous problems related to the synchronization of legislation, governance, implementation and management. Considering the specificities of local context, as well as its similarities to other post-socialist countries, the main aims of the article are to establish a relationship between planning, legislation and flood resilience, identify its (un)sustainable elements and provide an insight into the dynamic of their causal links whose effectiveness could be improved in given conditions. The main findings indicate an absence of a sustainable policy which would guarantee efficient implementation (regarding both planning documents and laws). Simultaneously, there were other challenges—from the lack of risk assessment to outdated regulations and general unpreparedness which led to severe damage of urban systems and local economy, while many lives were lost. Consequently, the article provides guidelines for new planning documents, suggesting measures that would increase the resilience of flood protection (applicable in both local and regional context), as well as the overall sustainability of the analyzed area and its ecosystem.
