Suitable and available land for settlement development in Cianjur Regency

Abstract

A merging of Jakarta and Bandung metropolitans influences the development of their areas, especially Northern of Cianjur Regency. Consequently, people are migrating to the cities caused an increasing population. Data showed that out-migration in Northern Cianjur is ten times higher (1 768 people) than in Southern Cianjur (182 people). It leads to experiencing uncontrolled advancement and arising problems, like the raising land demand for settlement development, but the land is limited. Therefore, this research aimed to address these particularities by modeling suitable and available land for settlement development in Cianjur Regency. Multi-criteria evaluation (MCE) and geographical information system (GIS) were collaborated to define the suitability criteria. Pairwise comparison was employed to set the criteria's weight. Spatial Plan and LP2B were carried out as limiting factors. Results showed that the most crucial consideration came from the disaster. The suitability classes in Cianjur regency are: highly suitable 36%; Suitable 7%; Marginally suitable 44%; and Not suitable 14%. In 2018, 85% of the land was available for settlement. However, it decreases to 2% in 2030 caused by land conversion for settlement use. Stakeholders’ preferences in determining the most critical criteria for land suitability are different. Therefore, it plays a crucial role in the next Cianjur’s settlement development planning. Implementing the Spatial Plan can minimize environmental problems such as land conversion. In addition, regarding the new regulation on LP2B, the spatial plan has to be updated to synchronize the plan between Spatial Plan and LP2B.
