The Mekong delta is Vietnam’s premier rice growing region, forming the livelihood basis for millions of farmers. At the same time, the region is facing various challenges, ranging from extreme weather events, saline water intrusion, and other anthropogenic pressures. This study examines how saline water intrusion and drought have affected rice...

As the backbone of Vietnam’s economy, the country has recently established a number of policies for promoting and investing in smart agriculture in the Mekong Delta, the country’s largest agricultural hub, to foster overall socio-economic development. However, water remains a critical constraint for crop production, with progress being hindered by...

The water balance in six selected crops (mung beans, tomatoes, maize, cassava, yam, and sweet potatoes) was determined at the field block scale in the Vietnamese Mekong Delta for two agricultural growing areas. A novel approach for the calculation of water balance was employed, which combined the reference crop evapotranspiration (ETo), derived...

The Launching Event of JICA 3R Project Phase 2 project was organized on August 2, 2022 in Da Nang, Viet Nam. The Launching Event was participated by the stakeholders in Da Nang city. During the meeting, the future plan for waste segregation and recycling promotion in Da Nang was discussed. IGES team presented the progress of the 1st Phase and its...

Information on the relationship between rainfall intensity, duration and accumulation frequency or return period (IDF) is commonly utilized in the design and management of urban drainage systems. Can Tho City, located in the Vietnamese Mekong Delta, is a city which has recently invested heavily in upgrading its stormwater drainage systems in the...

Protected places such as nature reserves (NRs) are used to maintain ecological balance, biodiversity, and support surrounding ecosystems. However, the development and operation of infrastructure such as dikes and sluice gates in NRs, as seen in the Vietnamese Mekong Delta (VMD), often adversely affects the hydrological regime and water quality at...

This study utilized MIKE 11 to quantify the spatio-temporal dynamics of water quality parameters (Biochemical Oxygen Demand (BOD 5), Dissolved Oxygen (DO) and temperature) in the Long Xuyen Quadrangle area of the Vietnamese Mekong Delta. Calibrated for the year of 2019 and validated for the year of 2020, the developed model showed a significant...

Because of its threat to the quality of freshwater resources and human health, arsenic (As) pollution is important to scientific communities and policymakers around the world. The Mekong Delta, Vietnam, is one hotspot of As pollution. Its risk assessment of different environmental components has been well documented; however, very few studies focus...

In Asia, Vietnam is one of the countries severely affected by energy shortages and climate change. Development of renewable energy from livestock wastes, e.g., production of electricity from biogas, is a solution for reducing greenhouse gas emissions and pollution from untreated livestock wastes, as well as energy shortages. So that, biogas...

This Policy Report forms part of the output from the project: "‘Closing the Loop: Innovation and Scaling Up to Solve the Problem of Plastic Pollution in Marine Areas in ASEAN Cities", supported by the Government of Japan. The report provides scientific-based evidence on the status of plastic pollution in Da Nang, in order to guide the development...
