This paper was aimed at estimating the forest aboveground biomass (AGB) in the Central Kalimantan tropical peatland forest, Indonesia, using polarimetric parameters extracted from RadarSAT-2 images. Six consecutive acquisitions of RadarSAT-2 full polarimetric data were acquired and polarimetric parameters were extracted. The backscattering coefficient ( σ o ) for HH, HV, VH, and VV channels was computed respectively. Entropy (H) and alpha ( α ) were computed using eign decomposition.
Landscape-Ecological Approach to Spatial Planning as a Tool to Minimize Socio-Ecological Conflicts: Case Study of Agrolandscape in the Taiga Zone of Russia
Landscape heterogeneity generates significant influences on economic activity. Present-day publications in landscape planning focus more and more on a participatory approach and a communication process. By contrast, we focus on nature-based criteria aimed at proper adaptation of planning decisions to natural landscape patterns. The paper proposes the framework aimed at considering geographical context, matter flows, and dynamic processes in projecting ecological network and perfect sites for various land use types as well as for choosing appropriate technologies.
Peri-Urban Organic Agriculture and Short Food Supply Chains as Drivers for Strengthening City/Region Food Systems—Two Case Studies in Andalucía, Spain
Discussions on food security in the Global North have raised questions about the capacity of peri-urban organic agriculture to provide sufficient healthy food for the urban market. Dealing with food security requires more attention to how to protect peri-urban organic farming systems from urban pressures while strengthening the sustainability of local food systems.
Quantifying the Economic Value of Ecosystem Services in Oil Palm Dominated Landscapes in Riau Province in Sumatra, Indonesia
Ecosystem services in oil palm plantations owned by smallholders in four villages in the Riau Province, Indonesia were identified and valued. Nine provisioning, three regulating and maintenance, one cultural ecosystem service, and a single ecosystem dis-service, were identified from interviews with 62 farming households. Direct and indirect market valuation methods were used to estimate the total economic value (TEV) of these services, which averaged USD 6520 ha−1 year−1 (range = USD 2970–7729 ha−1 year−1).
Bottom-Up Perspectives on the Re-Greening of the Sahel: An Evaluation of the Spatial Relationship between Soil and Water Conservation (SWC) and Tree-Cover in Burkina Faso
The Re-Greening of the West African Sahel has attracted great interdisciplinary interest since it was originally detected in the mid-2000s. Studies have investigated vegetation patterns at regional scales using a time series of coarse resolution remote sensing analyses. Fewer have attempted to explain the processes behind these patterns at local scales. This research investigates bottom-up processes driving Sahelian greening in the northern Central Plateau of Burkina Faso—a region recognized as a greening hot spot.
