“…Hence, diversity indices did not explain the variability in biomass carbon, SOC or TCS in this study. The absence of a statistically significant difference is in line with other studies [19,44,45].…”

Forests play an important role in combating the challenges posed by changing climate through sequestering carbon in their living biomasses and the soil. Tropical forests, which harbour a large number of species, are anticipated to play a great role in this regard due to the favourable growing environments. However, there is limited knowledge of the variability in carbon stock among land use types and its relationship with biodiversity. Therefore, this study assessed the variability in storing the different carbon pools among natural forest, woodland and khat plantation land use types. It also explored the relationship between biodiversity and carbon storage in the different carbon pools. Plant inventory and sample collection were undertaken following standard methods. In addition, soil samples were taken at three depth profile classes of 0–30 cm (top layer), 30–60 cm (middle layer) and 60–100 cm (bottom layer). Results of the study revealed that there was no statistically significant relationship between biodiversity and total biomass carbon, soil organic carbon or total carbon stock at a 95% level of confidence. The results indicated that the natural forest had the highest plant biomass (456.93 Mg ha−1) followed by woodland (19.78 Mg ha−1) and khat plantation (2.46 Mg ha−1). Consequently, the total carbon stock estimate of the natural forest (366.47 Mg ha−1) was significantly larger than that of the woodland (141.85 Mg ha−1) and khat plantation (125.86 Mg ha−1). The variation in total carbon stock among land use types arises from the variation in the total biomass carbon stock. The study results also revealed that soil organic carbon stock decreased with soil depth in all the land-use types. The findings of this study have implication of improving topsoil management in monoculture crops such as khat plantation and conserving natural forests for enhancing carbon sequestration potentials.

“…There were several studies of biodiversity in rural areas, especially Shannon Wiener diversity index on home garden (pekarangan) of 2.56-2.84 (Filqisthi and Kaswanto 2017), 0.99 for tree (Wiryono et al 2016) and 0.77-2.51 on small scale agroforestry (Choliq and Kaswanto 2017). On the other side the correlation of biodiversity and carbon stock were varied in each area, i.e.…”

“…On the other side the correlation of biodiversity and carbon stock were varied in each area, i.e. insignificant relationship at home garden (Filqisthi and Kaswanto 2017;Choliq and Kaswanto 2017), then positive and very weak relationship at collaborative forest (Mandal et al 2013). However, there were lacks on assessment of biodiversity index and carbon stock correlation on the whole rural area with varied landscape function.…”

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.
