“…Therefore, an average water level at Hanoi in the range of 1.0 m -1.7 m should be considered to maintain during the increased release. This proposal is consistent with the assessment of the General Department of Water Resources (Ministry of Agriculture and Rural Development) in the summary reports on water collection for winter-spring rice cultivation in the Midlands and Northern Delta continuously in the years 2020, 2022(MARD, 2020-2022. -Currently, when the irrigation works in the Red River Delta have not been rehabilitated to suit the situation of lowering water level, there should be, among the release periods, at least one release period at the maximum installed capacity of the Hoa Binh, Thac Ba and Tuyen Quang hydropower plants.…”

The Red-Thai Binh River system is an important water resource to the Northern Delta, serving the development of agriculture, people's livelihood and other economic sectors through its upstream reservoirs and a system of water abstraction works along the rivers. However, due to the impact of climate change and pressure from socio-economic development, the operation of the reservoir system according to Decision No. 740/QD-TTg was issued on June 17, 2019 by the Prime Minister of Government promulgating the Red-Thai Binh River system inter-reservoir operation rules (Operation rules 740) has some shortcomings that need adjustments for higher water use efficiency, meeting downstream water demand and power generation benefits. Through the results of water balance calculation and analysis of economic benefits from water use scenarios, this research proposed adjustment to the inter-reservoir operation during dry season in the Red River system. The result showed that an average water level of 1.0 -1.7 m should be maintained at Hanoi during the increased release period.

“…A satisfactory spectral signature was used to ensure minimum error among the land-uses to be mapped (Gao & Liu, 2010). The study has used the rule-based supervised classification -maximum likelihood classifier (MLC) algorithm for LULC classification for acquired images of 1989, 2001, 2011 et al, 2020a;Thien et al, 2022a). The post-classification refinement was used for the simplicity and effectiveness of the method to improve classification accuracy and reduce misclassifications (Harris & Ventura, 1995).…”

“…Remote sensing technology and Geographic Information Systems (GIS) have been widely developed and applied globally to research, monitor, and track LULC changes. Remote sensing satellites are the most-used data source to detect, quantify, and map both current land use and LULC changes because of their ability to collect multitemporal spatial data in the form of precisely geolocated, high-resolution images to which a range of processing techniques can be applied (Lu et al, 2004;Yang et al, 2019;Thien et al, 2022a). Many change detection techniques have been developed and used to monitor changes in LULC from remotely sensed data, such as vegetation index differences, image disparity, post-classification comparison, and principal component analysis (Lu et al, 2004;Afify, 2011).…”

Forests are essential in regulating climate and protecting land resources from natural disasters. In Vietnam's Dak Nong province, forest cover has changed significantly between 1989 and 2021. This study applies remote sensing and geographic information systems (GIS) approaches to detect negative changes in forest cover as well as other land cover types. The maximum likelihood classification tool was used to classify Landsat images for the years 1989, 2001, 2011, and 2021, with post-classification accuracy evaluated through kappa coefficient statistics. The potential to based classification on Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) to detect changes in forest cover compared with supervised classification was also evaluated. The land use and land cover change detection results show that the forest area decreased from 77.54% of the study area in 1989 to 33.97% in 2021, with a total forest loss of 2,953.48 km 2 and only 117.12 km 2 of newly planted forest during this period. Broadly, forest cover in the area has been severely reduced, often due to indiscriminate logging and expansion of agricultural land on the forest edge.
