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-...

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.

Urbanization and concomitant challenges pose a great threat to sustainable development. Urban and rural development interacts through the flows of people, materials, energy, goods, capital, and information. Without building sound urban–rural linkages, achieving development in one area could compromise it in another area. Achieving sustainable...

Droughts and floods are some of the major climatic hazards in the semi-arid areas of Sub-Saharan Africa (SSA). Climate change affects the periodicity and severity of such hazards, and eventually the well-being of many rural communities in the region, including semi-arid Ghana. Enhancing the resilience of local communities to droughts and floods...

Operational monitoring of vegetation and its response to climate change involves the use of vegetation indices (VIs) in relation to relevant climatic data. This study analyses the temporal variations of vegetation indices in response to climatic data (temperature and precipitation) to better understand the phenological changes in the Wa -West and...

Urban-rural linkages are an integral part of fostering development in both urban and rural communities. However, the focus on development tends to have an urban bias toward Sub-Saharan Africa (SSA) with an increase in urbanization. Ghana is one of the fastest urbanizing countries in SSA. This paper sought to identify the challenges of urban-rural...

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...
