Channel choice for sustainable log-based dried shiitake mushrooms production
To understand the sustainability of shiitake production as a traditional agroforestry system, we focused on the shiitake (Lentinus edodes) value chain. We conducted a descriptive analysis of the reasons for choosing distribution channels. Through semi structured interviews with 17 producers and wholesalers, we examine the social sustainability and diversification strategies of these channels. Log-cultivated shiitake mushrooms are typically grown …
How trust shapes the fate of natural resources co-management
Community-based natural resource governance is often promoted in the name of sustainability, yet long-term outcomes remain elusive. This study examines the impact of various types of trust as the underpinning factor for the long-term resilience of co-management arrangements. Using a four-type trust framework, dispositional, affinitive, rational, and procedural, the study compares trust trajectories across the prior to-, during-, and post-project …

Applying the DPSIR framework to qualitatively assess the globally important mangrove ecosystems of Indonesia
Indonesia has the largest extent of mangroves globally, supporting communities at the local scale while contributing to climate change mitigation at the global scale. Yet, they are highly threatened by multiple anthropogenic and natural stressors. Thus, in this study, we aim to qualitatively assess Indonesia’s mangrove ecosystems by conducting a literature review applying the Driver-Pressure-State-Impact-Response (DPSIR) framework. By using the f…
Potential of seagrass habitat restorations as nature-based solutions
Seagrasses offer diverse ecosystem services, yet, they are among the most threatened ecosystems. When degraded or destroyed, their services are lost or reduced in the process, affecting, for instance, local communities directly dependent on their livelihood provision. The Intergovernmental Panel on Climate Change (IPCC) reported that climate change is projected to worsen over time; thus, there is an urgent need for mitigation strategies in practi…
Capturing landscape values in peri-urban Satoyama forests
