Abstract
The main activities in the rural landscape are agriculture, involved natural resources management that compose the function of area as settlement, government services, social services and economy activities. These activities affected the rural landscape that changed plant diversities as well as carbon stock. The aim of this research was to evaluate biodiversity and carbon stock in the rural area of Cisadane Watershed. Two villages were defined on a purposive random sampling, i.e. Sukadamai and Bantarsari. The sampling plots were selected based on main land use type with size for tree was 20 m × 20 m, polewas 10 m x 10 m, sapling was 5 m x 5 m and seedling was 2 m x 2 m; with 3 replications. Similarly, other concentric plots were established. The number of plant species were counted, diameterat breast height (DBH) and height were measured. Then, carbon stock, plant diversity and the relationship was developed. The results showed that main land use in Sukadamai and Bantarsari Village consisted of settlement area, farmland, mixed farming and palm oil plantation. There were 106 species from 43 families that classified into 9 horizontal diversity based on function and 5 vertical diversity based on height. The values of Shannon-Wiener Diversity Index (H’) ranged 2.78–3.20. Estimated carbon stocks were 1.16–51.40 Mg ha−1 in research areas, respectively. These research concluded there was a negative correlation between species richness and diversity index with carbon stock in the village landscapes.
Highlights
Rural areas have main activities on agricultural work, including natural resources management that implied on landscape structure and function
Human activities affect landscape changes related to human needs and landscape service usage that involve demographic processes, economy, politics, cultures and biophysics (Nelson et al 2006)
The diameter at breast height (DBH) and height of vegetations were measured to determine the minimum number of sample plots based on coefficient of variance (Hairiah et al 2011)
Summary
Rural areas have main activities on agricultural work, including natural resources management that implied on landscape structure and function. Multifunctionality of rural areas were resident, government services, social services and economy activities. In Indonesia, rural areas have several types of landscape, mostly agricultural landscape. Jurnal Ilmu Lingkungan, 18(3), 610-616, doi:10.14710/jil.18.3.610-616 areas is the main service providing units for urban area, such as agricultural landscape has main role on food services in local, regional until global scale (White et al 2009). Human activities affect landscape changes related to human needs and landscape service usage that involve demographic processes, economy, politics, cultures and biophysics (Nelson et al 2006). Biophysical condition on rural landscape are varied such as farm area, forest, garden and other agricultural field have benefit on nature to maintain environment balance and sustainability (Lamarque et al 2011)
