Landslides, as modern processes on the surface of the terrain, present a challenge in spatial planning, planning and construction of new settlements, and construction of infrastructure facilities. A special challenge is the planning and construction of settlements and infrastructure facilities in hillside areas. The City of Sarajevo, with its four city municipalities, represents the most populated part of Sarajevo Canton. The situation is similar with non-urban municipalities. A special challenge is the illegal settlements created on hillside areas of the four city municipalities. Many hillside settlements were created unplanned, often within the scope of registered landslides and unstable terrain. The construction of such settlements was not accompanied by the construction of the necessary infrastructure (road communications, fecal and storm sewers), which poses a danger of starting new and reactivating calmed landslides. Society's commitment to climate change brings into focus the landslides that occur as a product of climate change. Special attention is paid to unplanned urban areas on the slopes, where the risk of landslides is increased due to climate change. According to official information, about 1,000 landslides have been registered in Sarajevo Canton. The data on the number of landslides in the area of the Sarajevo Canton date back deep into the past and as such have been updated on several occasions. The last addition of data was carried out in the phase of amending the Spatial Plan, in 2010, when the Terrain Stability Map of Sarajevo Canton was updated. In Sarajevo Canton, special attention is paid to the rehabilitation of landslides that endanger people and material goods, and to the stabilization of the terrain during the development of construction land, for which considerable financial resources are allocated from different levels of government (Federation, Canton and municipalities). Aggravating circumstance are regulations that only partially treat landslides. Certain regulations are unclear, some of them set strict requirements for emergency landslide rehabilitation, while certain regulations are in conflict. The institutional approach for the purpose of research, registration, rehabilitation and monitoring of landslides is not fully aligned with the current regulations. Jurisdiction is partially prescribed and as such is often unclear. The mandated competences of individual levels of government are not harmonized. Remedial measures were implemented on many landslides in the past period, but without clear indications of the effects of the remediation. As a solution to the problem, a proposal for the adoption of a single regulation on landslides was initiated. This paper cites the example of the Sarajevo Canton, where the activities for the adoption of a law on landslides were initiated, but ended unsuccessfully several times, with recommendations for further activities.
