Although masting in Southeast Asia is characterized by the interspecific synchronization of reproduction, little is known about the variation in regeneration strategies among sympatric tree species during major masting events. Herein, we examined the hypothesis that non-abundant species achieve greater seed survival per seed production at the pre-...

Cultural Ecosystem Services (CES) are non-material benefits that are indispensable for the health and well-being of communities. CES are often spatially explicit and fluctuate according to the knowledge, beliefs, and perception of users of the location. Therefore, understanding the spatial patterns of CES perceived by people from different...

農地において支柱を立てて上部空間に太陽光発電設備を設置し、下部空間では営農を継続しながら発電を行う営農型太陽光発電（ソーラーシェアリング）は、再生可能エネルギー導入量の拡大が見込めること、農業者の収入拡大による農業経営の改善や6次産業化の推進も期待できることから、政府として推進する方針が掲げられ、様々な制度で導入促進が図られている。 例えば、再生可能エネルギーの導入促進のために固定価格買取制度が導入されているが、営農型太陽光発電と野立太陽光発電で買取価格が区別されていない。しかしながら、両者は費用構造や事業リスクが異なり、導入によってもたらされる便益も異なることから、その性質に則して営農型太陽光発電の推進のための施策が導入されることが望ましい。...

ITTO project, PP-A/56-342B "ANALYSIS OF TIMBER LEGALITY ASSURANCE SYSTEMS AND GOOD PRACTICES IN VIET NAM FOR SUSTAINABLE TIMBER TRADE" conducted studies and developed two technical reports: Vietnam’s timber exports to Japan during 2018–2021 with a focus on products made using imported high-risk species. Using risk criteria stipulated by the Vietnam...

Peat swamp forests are one of the unique ecosystems of Southeast Asia. These forests are not only a large carbon stock, but also a refuge for rich biodiversity. To understand the faunal composition and the effect of land-use changes in peat swamp forests, we investigated ground-dwelling mammals and birds using camera traps in a natural peat swamp...

Tropical peatlands have increasingly been targeted for logging or conversion to plantations in recent years. Tropical peatlands are unique ecosystems rich in biodiversity, but they have not attracted as much researcher attention as tropical forests, for example. There is still limited understanding of the ecological significance of peatland...

The production of commodity crops such as oil palm, sugarcane, cotton or cocoa has important ramifications for sustainability at multiple spatial and temporal scales. Food security is among the most heavily debated impacts of commodity crop production, especially in developing regions characterized by high rates of malnutrition and food insecurity...

Envisioning positive scenarios that recognize the multiple values of nature is fundamental for designing transformative changes in local socio-ecological systems. This study developed a protocol with three specifications for operationalizing the Nature Futures Framework (NFF) in a landscape scenario analysis using a multi-objective optimization...

In this study, we propose a method for downscaling ecological footprint (EF) and biocapacity (BC) to a 1-km square resolution for a spatially flexible analysis of environmental burden balance. To conduct EF downscaling (by land type and consumption category) for all terrestrial areas of Japan, the grid population was multiplied by the scaled EF per...

Innovation history analysis of the transformation of paddy rice system on Sado Island from 1999 to 2019, which progressed with the reintroduction of crested ibis (Nipponia nippon), identified three key levers, i.e. multi-stakeholder collaboration, integrated local policies, and incentives, which, interacting one another and with seven leverage...
