Societal impact statement
Major staple crops are often introduced and cultivated in monocultures. Yams are staple crops native to the majority of low- and middle-income countries and can provide an alternative to introduced staple crops. [Correction added on 9 January 2026, after first online publication: In the preceding sentence, stable has been corrected to staple in this version.] We showed that lesser yams cultivated together with teak trees (planted
Abstract
Tropical peatlands storing ∼18–25 % of global peat volume contribute significantly to the global carbon cycle. To balance preservation and protection of tropical peatlands requires assessment of their ecohydrological conditions and continuous monitoring through seasons. This is challenging to achieve using in situ sampling, but there is a great promise to use C-band Sentinel-1 data for this due to its weather-independence, and particularly its increased
Abstract
Large-scale disturbance in peatland areas causes many wildlife species to suffer due to limited resources or habitat loss. Following the high attention to peatlands, some restoration efforts, such as canal blocking, have been undertaken to restore the hydrological condition of peatlands. Nonetheless, our understanding of peatland biodiversity post-canal blocking is still limited. Thus, we conducted a study in West Kalimantan to assess wildlife diversity in
Abstract
The performance of wood binders in particleboard is diminished by both expiration and improper storage. Those effects on citric acid powder, which is one of potential natural adhesives of particleboard for the future, is still unknown. This research investigated the effect of duration length of citric acid past the expiration and its storage conditions on the properties of Salacca frond particleboard. The effect of its binder content and pressing temperature
Abstract
Teak (Tectona grandis) is a valuable tropical timber species, but knowledge about its environmental adaptability for tree breeding is limited. Progeny trial is crucial for improving breeding materials as progeny performance and resilience to environmental stresses can be assessed for future breeding effort. In this study, we examined the variations in growth, crown architecture and leaf traits in a progeny trial in Indonesia. We retained the best components
Abstract
This study aimed to evaluate extractive composition and antioxidant activity of Acacia hybrid (Acacia mangium × Acacia auriculiformis) variety, namely Purwo Sri Ah015D wood, as a first step in future development to improve resistance to diseases. Wood powder from axial (bottom, middle, top) and radial (near pith and near bark) positions were successively extracted by n-hexane, methanol, and hot water solvents. The dried extracts (except n-hexane) were used
Abstract
In the tropical forests of Southeast Asia, the dipterocarp species stands out as the most significant tree group in terms of ecosystem stability and forestry management. Shorea macrophylla, found on Borneo Island, is particularly noteworthy for its rapid growth, high oil content nut production, and versatile timber characteristics, making it a prime candidate for plantation material in rehabilitating degraded forests. We collected population samples of S. macrophylla
Abstract
Social forestry is one of the Indonesian government’s programs to reduce deforestation and improve community welfare. After a decade, it is not yet known how the dynamics of land management related to the level of disturbance and recovery before and after the permit in the Tuar Tana Community Forest (HKm Tuar Tana) area in East Nusa Tenggara Province. This study aims to investigate the dynamics of land management by monitoring the level of disturbance and
Abstract
Urbanization in the Global South is increasingly influenced by large-scale infrastructure and frontier development, frequently exacerbating disparities and displacing marginalized populations. This paper situates Indonesia’s new capital (IKN) within debates on neoliberal urbanism and resource extraction, examining how long-established resource-based communities in East Kalimantan perceive IKN’s urbanisation. Research was conducted in a village within IKN’s
Abstract
Ultisols are commonly found in the tropics and are potentially suitable for plantation forestry. However, as well as being acidic (pH 5.0), they are commonly infertile and require fertiliser addition if commercial yields are to be achieved. A field experiment on a low productivity Ultisol at Lematang, South Sumatra, investigated the effect of seed source on the height, diameter and volume of Acacia mangium until age 36 months. Four seed sources were used:
