Groundwater can provide irrigation for rural communities where surface water is absent or unreliable. Technical, institutional and capacity limits have prevented rural communities from using groundwater for irrigation, and researchers have not demonstrated how to extract and use groundwater effectively for agriculture. A recent Australian-funded...

We use crowdsourced GIS data from OpenStreetMap to help automate the mapping of land cover in Landsat satellite imagery. The OpenStreetMap data had limited area coverage, but was useful for building a model which could classify land cover in the other areas.

We developed a method for mapping residential areas using freely available satellite imagery. The resultant residential area map can be used for risk assessment (e.g. to estimate the population living in a flood-prone area). Our method can be applied for flood risk assessment in other watersheds in the future.

The government of Indonesia has been promoting the system of rice intensification with emphasis on resource use efficiency and climate change adaptation benefits. One question remained to be seen is how the system of rice intensification compares with other technologies such as zero tillage, composting, and leaf color charts which have also been...

Pilot training programs were conducted in Cambodia for province and sub-province level government officers of the agriculture department to test the effectiveness of draft training modules on climate change adaptation. The pilot tested training modules include ‘Agriculture extension staffs at provincial level’ and ‘District and commune officers’...

Climate change poses a serious threat to developmental aspirations of most countries in Southeast Asia. The historical observations indicated general warming over the entire region with variations in the degree of warming and localized impacts. The Mekong River basin, which is the largest basin in the region that provides livelihoods for millions...

Cambodia is one of the most vulnerable countries to climatic and non-climatic vagaries in the Southeast Asia. Annual river floods along the Tonle Sap and Mekong Rivers are more common during monsoon season and are the most important developmental concerns in the region. Cambodia has put in place the National Committee for Disaster Management that...

Agriculture plays an important role in the national economy and food security of Indonesia. Increasing food production, while not adversely impacting the climate and local environment, is a challenge to be met. Indonesia has set an economy-wide emission reduction target of 20%. This would require rapid and substantial scaling up of mitigation...

This paper presents a case study of drought risk assessment and management in Svay Rieng province of Cambodia. Drought is a creeping disaster and has debilitating impacts on rural livelihoods and socio-economic conditions. Interviews with local communities, government administration, and non-governmental agencies indicated the lack of livelihood...

This article outlines ASEAN’s plan to transition toward a resilient and net-zero emission world, based on the ASEAN's first State of Climate Change Report launched on 7 October 2021.
