Abstract

Environmental degradation, biodiversity loss, climate change, and other environmental catastrophe are negative impacts caused by irresponsible land use change. It is vital to investigate the driver of the land use change to avoid undesirable environmental catastrophes. On the other hand, determinants of the occurrence of the land use change are very complex to be identified. In the last few years, floods hit many parts of the world, one of them was a massive flood in South Kalimantan in the last few years. There is a presumption that this disaster is caused by land use changes inside the watershed. This paper aims to identify the determinants of the land use change in Banjarbaru City and Banjar Regency inside Martapura and Maluka Watershed. This study found out that having a secure land tenure per se does not incentivize landowners to prevent land use change. However, having a secure land tenure is a crucial factor in affecting land use change if the land they own is in large size. Having secure land tenure with large land size affects the occurrence of land use changes significantly by conducting agricultural and plantation extensification. This situation depicts that agricultural and plantation extensification exists in the rural area of South Kalimantan, which is triggered by economic profit orientation. Thus, the accumulation of secure land tenure and large land size need to be considered as land use change determinants for current and future’s land use policy in the context of Indonesia.

Abstract

Land cover change is a prevalent thing in Indonesia. This phenomenon often causes deforestation rates to continue to increase every year, which can cause various natural disasters. This study will look at changes in land cover, make land cover prediction models, and see the relationship between land cover changes and the flood disaster that occurred in Banjarmasin City and its surroundings. Remote sensing is used to see changes in land cover from year to year with GlobeLand30 satellite imagery. Satellite imagery processing is carried out using the Cellular Automata – Markov Chain method to see the land cover prediction. The results show that the most significant land cover change from 2000 to 2020 is experienced by built-up land and forests, while in 2030, forests are predicted to experience deforestation of 356 km2 from 2020. The deforestation will cause catastrophic flooding in 2021, where flooding extends to areas that are not estimated to be high flood hazards, with 111 flood points located in the plantation area.

Abstract

Jakarta Bay is a bay supporting the economy of thousands of nearby fishermen. Therefore, the reclamation in Jakarta Bay raises many environmental, economic, and social problems. During this reclamation, dredging and stockpiling activities increase the turbidity of the waters. This research aims to determine the changes in the distribution of total suspended solids (TSS) after reclamation using Sentinel 2A satellite imagery from 2016 to 2022. This research implemented the previous algorithm to produce the distribution of TSS in Jakarta Bay for attaining TSS values from Sentinel 2A satellite imagery processed by Google Earth Engine with overlay analysis method in a geographic information system. Spatial data were obtained by extracting TSS values using the previous estimation algorithm, namely the Budhiman algorithm, with a correlation coefficient of -0.745 and NMAE of 0.167. Based on the data processing results, it was found that the distribution of TSS from 2016 to 2022 was at a moderate level, which had a relatively significant influence on fisheries, requiring the fishermen to go to the open sea farther from the coast. This shows that reclamation carries no impact on the life of marine biota in Jakarta Bay.
