In this paper, we provide a novel approach to distinguish livable urban densities from crowded cities and describe how this distinction has proved to be critical in predicting COVID-19 contagion hotspots in cities in low- and middle-income country. Urban population density—considered as the ratio of population to land area, without reference to floor space consumption or other measures of livability—can have large drawbacks.

Institutional setup in the land administration system plays a crucial role in the successful functioning of modern land administration. The institutional setup, whether separated for urban and rural land administration or unified, is responsible for implementing the legal and policy framework. In most regions of Ethiopia, including the Amhara National Regional State, the institutional setup is separated, which results in increasing difficulties to administer land efficiently.

Water erosion is a phenomenon that significantly damages agricultural land. The current land fragmentation in Slovakia and the complete ambiguity of who owns it leads to a lack of responsibility to care for the land in its current condition, which could affect its sustainability in the future. The reason so much soil has eroded is obvious when looking at current land management, with large fields, a lack of windbreaks between them, and no barriers to prevent soil runoff. Land consolidation might be the solution.
