Radar imagery helps detect surface water in rice paddy fields in An Giang

19/09/2026
Whether rice paddy fields are inundated or dry produces distinct signatures in radar imagery. Building on this characteristic, researchers from the Southern Institute of Water Resources Research and the Vietnam National Space Center, Viet Nam Academy of Science and Technology, tested a method for detecting inundation in rice paddy fields in An Giang Province, providing an additional source of data for monitoring water regimes and estimating methane emissions from rice cultivation.

A research team from the Vietnam Academy for Water Resources—including Nguyen Thanh Hung, Vu Dinh Cuong, Trieu Quang Quan, and Nguyen Anh Hung—has developed an integrated technological solution that combines flood and inundation forecasting with modern communication tools. The study aims not only to enhance forecasting capacity but also to ensure that warning information reaches the right people at the right time under emergency flood conditions.
  • Treating pesticide wastewater: Performance and limits of the H₂O₂/UV system in an Isoprothiolane case study

    Treating pesticide wastewater: Performance and limits of the H₂O₂/UV system in an Isoprothiolane case study

    The use of pesticides is an integral part of modern intensive agriculture. Alongside their effectiveness in controlling pests and diseases, however, comes the risk of environmental pollution from wastewater generated during the production, formulation, and application of chemical active ingredients. Of particular concern is the fact that many pesticide compounds are poorly biodegradable, persistent in the environment, and prone to bioaccumulation, posing major challenges for wastewater treatment.

    Digitizing habitats of Cinnamomum parthenoxylon: Cloud-based modeling maps climate-adaptive areas in Vietnam’s Central Highlands

    Cinnamomum parthenoxylon, an endangered tree species of the Lauraceae family, is facing rapid habitat contraction under the combined pressures of climate change and forest degradation in Vietnam’s Central Highlands. A research team consisting of Pham Mai Phuong, Nguyen Thi Thu Nga, Nguyen Quoc Khanh, Nguyen Duy Liem, and Vu Dinh Duy employed the cloud-based Google Earth Engine (GEE) platform and the MaxEnt algorithm to develop habitat suitability maps for both current and projected future climates. This study marks the first application of a multi-scenario climate projection framework to assess the species’ adaptive potential toward the end of the 21st century. The findings provide an important scientific basis for the conservation, restoration, and sustainable planning of C. parthenoxylon in key provinces such as Lam Dong and Dak Nong (now part of the newly established Lam Dong Pprovince).
  • Vietnam’s cassava production reveals deep water inefficiencies across regions

    Vietnam’s cassava production reveals deep water inefficiencies across regions

    Amid accelerating climate change and shrinking water resources that are reshaping global food security, a new study by Trinh Phuong Ngoc, Nguyen Thu Thu Huong, Nguyen Tien Dat, and Dinh Quang Hung from Tan Trao University and the Institute of Environmental Science and Technology (Hanoi University of Science and Technology) provides the first systematic quantification of the water footprint of cassava production in Vietnam. The findings reveal stark regional disparities—some areas rely on thousands of cubic meters of supplemental irrigation to maintain yields, while others require almost no irrigation at all thanks to abundant rainfall and natural water availability. These results underscore an urgent need to restructure cassava-growing regions and promote more sustainable water use in agriculture.
