Behavioural insight interventions, alongside traditional policy measures, offer promising solutions to nudge consumers away from single-use plastic consumption. This comprehensive Guidance Note shares practical lessons on the application of behavioural insights in four ASEAN countries: Indonesia, the Philippines, Thailand and Viet Nam. The...

Open waste burning is a widespread practice that is provoked by a lack of systematic waste collection, the unavailability of other disposal options, and inadequate land for the final disposal of the collected waste, especially in low- and middle-income countries. From a global perspective, two billion people have no waste collection at all, and the...

Tracking decarbonization effects requires a model for the identification of spatial energy demands on city facilities. However, most developing countries lack detailed discrete time and device-specific energy demand data. In this study, we installed multiple energy demand monitoring systems that could observe electricity demands at the device level...

Purpose Takakura Composting Method (TCM) is a simple and cost-effective aerobic composting method using locally available materials and has been widely introduced in Indonesia and other countries. This study tracked the progress of scaling the TCM up to 1 tonne/day of organic waste input at the decentralised composting centre in Bandung City...

The Sustainable Development Goals (SDGs) present a complex system of 17 goals and 169 individual targets whose interactions can be described in terms of co-benefits and trade-offs between policy actions. We analyse in detail target-by-target interlinkage networks established by the Institute for Global Environmental Strategies (IGES) SDG...

Peatlands in Indonesia are subject to subsidence in recent years, resulting in significant soil organic carbon loss. Their degradation is responsible for several environmental issues; however, understanding the causes of peatland subsidence is of prime concern for implementing mitigation measures. Here, we employed time-series Small BAseline Subset...

In fast-growing coastal cities, dependable public transport, diversity of modes, and social inclusion are among several factors that contribute to resilient transport. However, these factors depend critically on whether key ridership segments are aware of the benefits of public transport. This article describes the effects of an awareness raising...

The spread of online taxi services is transforming mobility patterns in many of the world’s rapidly motorizing cities. Yet few studies have systematically assessed which factors are behind this transformation. This article fill this critical knowledge gap for the three fast-growing cities of Indonesia, namely, Semarang, Bogor and Bandung. The...

世界的に木材原料の天然林資源から人工林資源への移行が進行している。そのプロセスを理解するため、天然林コンセッションの資源が減少し．人工林コンセッション、土地転換材、住民林業からの木材生産が増大するインドネシアにおいて、国内の木材と木材製品の主要な生産地、また両者の関係がどのように変化したのかを分析した。インドネシアでは、1990年代までは主にカリマンタン．スマトラの天然林コンセッションで木材生産が行われ、域内で合板や製材品が生産されていた。2000年代以降、スマトラにおけるパルプ・チップ生産がインドネシアで最も木材を消費する木材製品製造業となり、原料は主にスマトラの人工林コンセッションからの木材が使われているが、他の地域の人工林コンセッションからの木材や...
