Spatial analysis of coastal and marine ecosystem services at Bima Bay, West Nusa Tenggara, Indonesia

Abstract

Abstract Bima Bay, as an ecosystem, is very interesting to understand in its relation between the changes in land use/land cover with ecosystem services. The purpose of this study was to determine the condition of ecosystem services in Bima Bay. The data analysis methods used were: field surveys, independent interviews with stakeholders regarding the direction of development in the Bima Bay area, and spatial information sourced from relevant documents. The results showed that the highest ecological integrity index value was found in West Rasanae Sub-district at 0.5592 and the lowest integrity value was in Soromandi Sub-district at 0.3051. The highest value of the inventory service index was found in West Rasanae Sub-district at 0.1526 and the lowest was Soromandi Sub-district at 0.0981. The highest index value for regulating services was found in West Rasanae Sub-district at 0.3333 and the lowest was Soromandi Sub-district at 0.2119. The highest index value for culture services was 0.5143 and the lowest was Soromandi Sub-district at 0.2143. Meanwhile, the value of the index value of the Bima Bay ecosystem services budgets was -1.8138, this showed that human demand for ecosystem goods and services was greater than the ability to provide them (supply<demand).
