Forest development

Nowadays, most of the mountainous provinces and central highland of Viet Nam’s forests area are decreasing in quality as well as quantity seriously. Consequence, the problem of environmental pollution is becoming more and more serious in Viet Nam such as soil erosion, climate changes, land slide, flood and drought, air pollution, water pollution, etc.

Plastic is one of the most handy materials that man has ever invented. With its cheap, durable, and convenient properties, plastic is used in almost all areas of life. Along with economic development, plastic waste is becoming a big challenge for the community and society, significantly affecting the environment, public health and marine ecosystems, including mangrove forests.

The paper "Applying machine learning algorithms to classify forest cover type from sentinel 2 MSI data" presents the results of forest cover classification in Dak Lak province from Sentinel 2 optical satellite image data using machine learning techniques. Sentinel 2 MSI images taken in November 2015 and December 2020 are used to classify forest cover objects and then evaluate forest cover changes in the period 2015-2020.

The paper "A combination of ALOS-2, Sentinel-1 imagery for rapid deforestation detection in Vietnam" focuses on combining two different wavelength SAR data types (C-band and L-band), HV and HH polarizations to detect clear-cut and forest fires. The author uses the method of comparing the backscatter values before and after deforestation to detect forest loss, with the Sentinel-1 time series data using the RCR (Radar Change Ratio) method, while the three ALOS-2 image scenes use the RGB composite method.

The study "Mangrove degradation assessment using WorldView-2 imagery for Mekong delta, Vietnam" reported research findings on mangrove degradation assessment using WorldView2-based NDVI and NDVI differencing techniques. NDVI was estimated through analysis of satellite images band ratio to give an indication of greenness and healthy forests. The findings contribute to identifying areas with high levels of degradation that need to prioritize restoration and conservation solutions.

The aim of this paper was to quantify spatialtemporal dynamics of mangrove forests Quang Yent town, Quang Ninh province from 2017 to 2019 using Sentinel 2A imageries. It then estimated above-ground mangrove biomass and carbon stocks, and their changes. These findings were used to inform coastal management planning and policy development, particularly related to sustainable management of mangrove forests and likelihood improvements in the face of a changing climate in Vietnam.

Quang Truc forest (QTF) is a remote area in the South-West of Dak Nong province, Vietnam, which is well known for valuable timber species representative for central highland of Vietnam with different globally and nationally threatened species. However, the general understanding of plant diversity of QTF has been still poorly known. The objectives of this paper are to figure out the plant diversity of QTF and compare that with other protected forest areas in Dak Nong province, in order to provide scientific evidences for conservation and sustainable development.
