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...

Central Asia's semi-arid regions, vital for sustaining vast populations and diverse ecosystems, are under heightened environmental stress. Among these regions, the Tuul River Basin, home to over half of Mongolia's population, characterizes the challenges posed by contemporary environmental shifts. This basin, a hub in Mongolia's socio-economic...

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...

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...

The main aim of the current study is to produce and validate flood vulnerability rate (FVR) maps of this area relying on geospatial data. Vulnerability criteria were...

Climate change and overpopulation have led to an increase in water demands worldwide. As a result, land subsidence due to groundwater extraction and water level decline is causing damage to communities in arid and semiarid regions. The agricultural plain of Samalghan in Iran has recently experienced wide areas of land subsidence, which is...

This chapter evaluated the potential of SBAS InSAR technology to monitor the land subsidence and its environmental impacts in tropical peatland area from Sintang Regency, Borneo Island, Indonesia. Result shows that 0.354 Mt carbon was lost annually due to this peat subsidence. Hence, it is suggested that periodic monitoring of Indonesian peatlands...
