Researchers from Graduate School, Universitas Padjadjaran, have conducted a comprehensive survey of avian diversity in the human-altered landscapes of Paseh Sub-district, Sumedang. Using point-count bird surveys, they recorded 74 species (3,115 individuals) across various habitats. By analyzing landscape structure metrics with Fragstats software and applying Spearman correlation, the team found that bird diversity was positively associated with features such as larger patch area, increased patch number, longer edges, complex shapes, and lower landscape heterogeneity. In terms of land use, bird diversity was highest in mixed gardens (H = 3.13), followed by rice fields and settlements, with an overall moderate diversity index of H = 2.91.

This research holds vital implications for achieving several Sustainable Development Goals (SDGs). It supports SDG 15 (Life on Land) by highlighting how diverse landscape structures—especially mixed-use and garden ecosystems—can act as key refuges for bird species in human-dominated areas. It also advances SDG 11 (Sustainable Cities and Communities) by offering data-driven insights for integrating biodiversity considerations into landscape planning. Additionally, the findings bolster SDG 17 (Partnerships for the Goals) by demonstrating the power of interdisciplinary collaboration—combining biological, geographical, and sustainability science expertise—to inform effective, nature-friendly land-use strategies.
