Abstract
Coastal areas have been growing massively worldwide. The fast growth also affects the land value in either a positive or a negative way. Many scholars have studied land value and the factors that affect it in areas prone to sudden-onset disasters. In contrast, studies on urbanized coastal areas that suffer from slow-onset disasters are still lacking. Using a case study from Semarang City in Indonesia, this research aims at ameliorating this limitation. To comprehensively understand the aim, two research questions are addressed: (1) What is the distribution of land value in urbanized coastal areas? (2) How do the different distribution factors determine the land value? Based on in-depth interviews with key persons, map analyses, and desk studies, this research discovers that land value is distributed randomly among coastal areas. The dynamics of land value are determined by road access, distance, and accessibility to the city center and CBD, public facilities, transportation facilities, population composition, physical environment, and disasters. Surprisingly, the coastal areas in Semarang that experience combined disasters showed that disasters could not decrease the land value; the value in some areas is constant or even increasing. This shows the different impacts of disasters on land value for slow-onset disasters and sudden-onset disasters.
Highlights
Statistics indicate a swift increase in annual world population
Using a case study from Semarang City, which is one of the areas most prone to coastal disasters and environmental damages in Indonesia, this research aims to contribute to the study of the urbanized coastal areas susceptible to slow onset and complex interrelated disasters by understanding the factors affecting the land value in that type of area
To comprehensively understand the aim, two research questions are addressed: (1) What is the distribution of land value in urbanized coastal areas? (2) How do the different distribution factors determine the land value? The first question is expected to give an understanding of how the distribution of land value is in different localities and morphological settings
Summary
In the middle of 2019, the global population was about 7.7 billion, an increase of about 1 billion in 12 years. This number is projected to be 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100 [1]. Small and Nicholls [5] even showed that around one-fifth of the global population, i.e., 1.2 billion people, lived within 100 km from a coast. This number is predicted to become half of the global population in 2030.
