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-...

The problem of water scarcity and clean water in sub-Saharan Africa is a growing concern. This study aims to quantify the water quality on a temporal scale in the Doorndraai dam site in sub-Saharan Africa to design possible management options. Here, an integrated approach using both in-situ measurements of water quality parameters and remote...

This summary report presents the results of the technical analysis of the third biennial update report of Malaysia, conducted by a team of technical experts in accordance with the modalities and procedures contained in the annex to decision 20/CP.19. The author at IGES (Chisa Umemiya) served as one of the co-leads.

Considering the well‐documented impacts of land‐use change on water resources and the rapid land‐use conversions occurring throughout Africa, in this study, we conducted a spatiotemporal analysis of surface water quality and its relation with the land use and land cover (LULC) pattern in Mokopane, Limpopo province of South Africa. Various physico...

The aim of this two-volume book series is to highlight some of the most pervasive sustainability challenges that Sub-Saharan Africa faces. The two volumes contain 20 chapters that illustrate very diverse sustainability challenges throughout the continent, adopting interdisciplinary and problem-oriented research approaches, and methods from the...

Rapid development in Bintulu has resulted in large-scale changes in land use, especially the conversion of forests into oil palm plantations and industrial tree plantations. Using high-resolution satellite imagery, we analysed land-cover types in the Kemena–Tubau–Lower Jelalong region of Sebauh subdistrict and classified them into nine major land...

This chapter discusses the historical formation and current features of society in the Kemena and Tatau river basins in Bintulu, central Sarawak, where various ethnic groups live close together in a small area as a result of the historical migration of each group. We refer to previous studies and to interviews we conducted, mainly in 2011...

While Borneo is a global biodiversity hotspot, its species-rich natural rainforests have been degraded and deforested in the past few decades by unsustainable shifting agriculture, commercial logging and the rapid development of industrial tree and oil palm plantations. Populations of some wildlife species have decreased drastically due to...

The island of Borneo is regarded as one of the most biologically rich regions in the world, containing some of the oldest remaining tropical rainforests. However, it also suffers high levels of deforestation and degradation to meet the demands for timber extraction and agricultural activities. In Sarawak, areas designated as permanent forests...

It is important to understand carbon (C) dynamics in terrestrial and coastal ecosystems in order to develop a strategy to control carbon dioxide effluxes. However, the factors determining concentrations of riverine carbon are still largely unknown, especially in Southeast Asia. We investigated the spatial distribution of dissolved and particulate...
