Land cover monitoring is one of the mechanisms carried out by Hasanuddin University to capture the condition of its territory. Monitoring of land cover activities on Unhas Campus is carried out periodically from year to year. The monitoring method is carried out through a Geographic Information System (GIS) approach.
Until recently, land cover monitoring activities have been carried out and analyzed in 2001, 2009, and 2021 through a Geographic Information System (GIS) approach. A complete results of the land cover monitoring in a form of visual description of the condition of the region can be accessed via the following link https://kampusunhas.zonakata.id/.
Land cover monitoring at Unhas Campus is categorized into 4 types of land cover, namely forest areas, buildings, open areas, and lakes. Tabulated land cover conditions based on monitoring results through a Geographic Information System (GIS) approach are shown in the following table.
Table 1. Land Cover Conditions on Hasanuddin University Campus using a Geographic Information System (GIS)approach 2001, 2009, and 2021.
| No | Land Cover | Area of land coverage | |||||
| 2001 | 2009 | 2021 | |||||
| Ha | % | Ha | % | Ha | % | ||
| 1 | Forest | 15,00 | 9,87 | 38,97 | 25,64 | 69,35 | 45,62 |
| 2 | Buildings | 16,90 | 11,12 | 24,33 | 16,01 | 28,85 | 18,98 |
| 3 | Open Spaces | 112,93 | 74,30 | 81,58 | 53,67 | 46,85 | 30,82 |
| 4 | Lake | 7,17 | 4,72 | 7,12 | 4,68 | 6,94 | 4,57 |
| Total | 152,00 | 100,00 | 152,00 | 100,00 | 152,00 | 100,00 | |
Based on Table 1, there is an increase in forest area on the campus from 2001 to 2021. During these periods, area for forest has been wider due to expansion of urban forest area on campus as an impact of Hasanuddin University being granted as one of Makassar city’s Green Open Spaces by the Mayor in 2008. While area of the forest increase, construction of buildings on the main campus also were undertaken by the University. This construction had an effect on decreased area for open spaces from 2001 to 2021. Nevertheless, this changing of land cover for buildings eventually did not affect the composition of land cover in the campus of Hasanuddin University that should maintain 60% for green open spaces. Table 1 also indicates that biodiversity in campus area, especially for flora listed in the national conservation list are monitored regularly.
