| dc.description.abstract | Climate change and biodiversity loss are global challenges that also affect
university campuses. As a biodiversity campus and a Green Campus, IPB Dramaga
Campus plays an important role in providing ecosystem services through carbon
storage, carbon sequestration, and biodiversity conservation. However, ongoing
infrastructure development may reduce the ecological functions of the campus
landscape. Therefore, this study aimed to identify land cover changes, analyze
carbon storage and carbon sequestration, evaluate tree biodiversity, and formulate
landscape service management recommendations for IPB Dramaga Campus. The
study began with a land cover change analysis using the Random Forest
classification method on satellite imagery from 2013, 2018, and 2023. Carbon
analysis was conducted using i-Tree Eco software based on vegetation inventory
data collected from 98 randomly distributed sample plots. Biodiversity was
assessed using the Shannon-Wiener, Simpson, Margalef, and Menhinick indices,
while management recommendations were developed through SWOT analysis. The
results showed that vegetation cover decreased from 146.95 ha in 2013 to 128.97
ha in 2023, representing a decline of approximately 12.2%. In contrast, built-up
areas increased from 67.14 ha to 99.98 ha, an increase of approximately 48.9%,
while open land decreased from 29.55 ha to 13.56 ha. Despite these changes, tree
cover still occupied 128.97 ha, accounting for approximately 50.46% of the total
campus area, indicating that the ecological functions of the landscape remain
relatively well maintained. The vegetation of IPB Dramaga Campus was estimated
to sequester 3,555 tons of carbon annually and store 29,300 tons of carbon. The
species contributing most significantly to carbon-related ecosystem services were
Samanea saman, Tectona grandis, Ficus benjamina, and Aquilaria malaccensis.
The high carbon storage and sequestration capacities were primarily associated with
the presence of large, broad-canopied, and long-lived trees. A total of 610 tree
individuals representing 140 species from various families were identified. The
Shannon-Wiener index (3.72), Simpson index (0.99), and Margalef index (26.73)
indicated high levels of species diversity and richness. Correlation analysis revealed
a weak relationship between biodiversity and carbon storage. Based on the SWOT
analysis, the recommended priority strategies include protecting areas with high
biodiversity and carbon storage, utilizing spatial technologies for environmental
monitoring, developing a GIS-based tree database, and establishing ecological
protection zones. The findings demonstrate that integrating carbon, biodiversity,
and spatial technology into landscape planning can support more sustainable
landscape management and strengthen the role of IPB Dramaga Campus as a
biodiversity campus and Green Campus in the future. | |
