## 3 Theory
### Land Administration for Community Disaster Resilience  
Concerning issues on relocating people during the recovery phase to a safer place, land administration is proposed as a domain on the assessment of CDR. People who were affected by the 2018 landslide in the municipality of Sukabumi and the 2018 tsunami in the municipality of Pandeglang [28], as well as casualties of the 2004 tsunami in the municipality of Banda Aceh [29], returned to land even though the areas were already defined as restricted zones due to their proneness to the related disaster. The main reason for the fatalities caused by the 2018 landslide in the municipality of Sukabumi and the 2018 tsunami in the municipality of Pandeglang to return to their land or nearby areas was the strong connection between the people and their land [28].  
Land administration is defined as a process run by the government using public or private sector agencies related to land tenure, land value, land use, and land development [40]. Land administration regulates relationship between people and land by defining rights, restrictions, and responsibilities of the people to their land [41]. The success of the mentioned process mostly depends on the existence of a sound land administration system, which is an infrastructure for implementation of land policies and land management strategies, while land management is an activity associated with the management of land to achieve sustainable development goals [40].  
While land administration regulates the existing relationship, it is argued that such a relationship may be intervened. In the scope of disaster risk management, relocating people, particularly those who are affected by disaster, to a safer zone is considered as among the interventions for the people-land relationship. Furthermore, land administration may regulate the people-land relationship at every phase of disaster risk management [42]. Thus, land administration is a powerful tool to ensure a successful disaster risk management.  
Furthermore, land administration plays an important role on the recovery from disaster, as well as developing CDR. The revision of spatial planning of the municipality of Banda Aceh was one of the important processes at the recovery phase of the 2004 Great Tsunami of Aceh [29]. The spatial plan was developed based on the proneness of the municipality to tsunami, which pushed the residential areas to safer grounds. At the recovery phase after the 2018 Lombok Island Great Earthquake, land readjustment was initiated to create safer neighborhoods in Lombok Island [43]. The dense settlements, unreliable houses, and inadequate access to evacuation areas were among the main causes of casualties in the aforementioned earthquake, which became the main considerations on the performance of land readjustment [44].  
A good land tenure system was proven to facilitate the disaster recovery phase, as well as to lead to a resilient community to disaster. Due to the 2004 Great Tsunami of Aceh, official land records were mostly damaged [29]. On the other hand, during the recovery phase of the 2018 Great Earthquake of Lombok Island, the land readjustment process included the first-time land registration for most of affected parcels [43].  
In the scope of development of CDR, several subcategories were proposed. The subcategories are social, economic, and physical functions of land for the people and community. These subcategories were proposed based on the social, economic and physical domains of the people-land relationship [40].
