A Green Criminological Exploration of Illegal Wildlife Trade in Vietnam

Illegal wildlife trade is a pervasive and destructive crime that is contributing to biodiversity loss and species extinction around the globe. This is particularly true in Vietnam where, it is proposed, the convergence of four factors creates the conditions for the illegal wildlife trade to flourish. The human-centered approach to Vietnam’s diverse ecosystem, historic consumption of wildlife, rapidly developing economy, and embryonic environmental legislation has resulted in the continued degradation of a unique and important environment. Furthermore, until recently criminological research of such green crimes has either been lacking or equally human-centered. This article details the nature and extent of wildlife trafficking in Vietnam and introduces to this context an expanded notion of harm, including the environment and other species, of a green criminological perspective to this exploration. The aim is that, by proposing a new framework in which to evaluate the illegal wildlife trade and other green crimes in Vietnam, new and innovative strategies addressing the convergent factors might be developed that will aid in stopping the illegal wildlife trade and other green crimes

An alternative approach to classify illegal logging: The case in Vietnam

This article examines the different kinds of illegal logging that takes place in Vietnam, challenging the typical approaches to understanding and classifying the various criminal activities involved. We argue that either overlooking the classification of illegal logging or relying solely on illegal timber volumes and legal descriptions to categorise the crime is not sufficient to comprehend its diverse nature. This leads to inappropriate measures to tackle the crime. Instead, this study suggests that illegal logging should be categorised into three types, which are fundamentally distinctive, not only with regard to the volumes of illicit timber and the legislative definitions of the crime, but also (and more importantly) with reference to the attributes of harvesters, the degree of their involvement and their motivations, and the level of organisation involved in criminal commissions

Timber Trafficking and its Impacts on Human Security in Vietnam

As with other forms of green crime, timber trafficking is frequently overlooked by traditional criminology. This research is an exploratory investigation into the problem of timber trafficking in Vietnam, which aims to obtain a detailed understanding of the typology of, victimisation from, and key factors driving this crime. To achieve this aim, 41 semi-structured interviews with seven different cohorts (environmental police, investigative police, forest protection officers, commune authorities, forest-based inhabitants, timber traders, and green NGO staff) were conducted. Over one hundred pages of official documents (criminal case records, operational reports, and conference papers), and more than two hundred relevant newspapers were collected and analysed to enhance and triangulate the primary data. This research reveals a multifaceted typology of timber trafficking in Vietnam, comprising five different components: harvesting, transporting, trading, supporting, and processing. Each of these components is further constituted by distinctive, parallel forms of illicit operation. There are, for example, three parallel forms of illegal timber harvesting, termed small-scale, medium-scale and large-scale (SSITH, MSITH and LSITH). While having certain overlaps, in general SSITH, MSITH and LSITH are fundamentally distinctive not only in terms of the volumes of illicit timber they produce and the methods of illegally felling trees they employ, as typically identified in the previous studies, but more importantly in terms of the harvesters‘ attributes, their motivations, and the sophistication and security implications of the criminal operations. It is thus argued that the typology of illegal timber harvesting in this research challenges the typical classification in the existing literature, and offers an alternative way of understanding more comprehensively the dynamic of illegal logging. Regarding the victimisation from timber trafficking, due to the employment of a broad conceptual framework of human security, it is revealed that timber trafficking has substantial harmful impacts on all seven elements of human security: economic, food, health, environmental, personal, community, and political. These impacts are closely interconnected, but vary between different groups of victims. These findings culminate in the proposal that there are three main typical characteristics of green victimisation: suffering hierarchy, victim-offender overlap, and multidimensionality. Additionally, the employment of a human security paradigm in this research leads to another proposal that it is highly achievable and productive to integrate perspectives from the field of security studies into the discipline of green criminology, for the purpose of systematically examining green victimisation. Finally, this research offers five solutions to control timber trafficking in the context of Vietnam, by refining the current policy framework of forest governance and improving the efficiency of law enforcement

Detection of a Sudan dye at low concentrations by surface-enhanced Raman spectroscopy using silver nanoparticles

Sudan dyes are red colorants banned from use for food due to their toxic properties. However, because of the cheapness, they are sometimes adulterated into food illegally. Currently surface-enhanced Raman spectroscopy (SERS) is emerging as a good method to detect residues (including trace amounts) of Sudan dyes in food. In this report we present the SERS detection of Sudan I (a type of Sudan dyes) to concentrations as low as 1 ppb, using a very simple SERS substrate, which is made from silver nanoparticles chemically deposited on silicon surface

Microfluidic Chip for Trapping Magnetic Nanoparticles and Heating in Terms of Biological Analysis

In this study, we reported the results of the design and the fabrication a planar coil in copper (square, a = 10 mm, 15mm high, 90 turns), these planar coils were integrated in a microfluidic chip for trapping magnetic nanoparticles and local heating applications. A small thermocouple (type K, 1 mm tip size) was put directly on top of the micro-channel in poly(dimethyl-siloxane) in order to measure the temperature inside the channel during applying current. The design of planar coils was based on optimizing the results of the magnetic calculation. The most suitable value of the magnetic field generated by the coil was calculated by ANSYS® software corresponded to the different distances from the coil surface to the micro-channel bottom (magnetic field strength Hmax = 825 A/m). The magnetic filed and heating relationship was balanced in order to manipulating the trapping magnetic nanoparticles and heating process. This design of the microfluidic chip can be used to develop a complex microfluidic chip using magnetic nanoparticles

Management and monitoring of air and water pollution by using GIS technology: Research article

The need for a green clean living environment is increasing today, with the boom of the socioeconomic development, educational level. However, the environmental pollution becomes an alerted global issue due to the large amount of wastes discharged making this need to be not easily met at the moment. Greenhouse gas emission mainly from energy, transport and agricultural land use is causing climate change because of their long atmospheric lifetime and trapping the heat in the atmosphere. Harmful effects and damages caused by environment pollution and climate change are unpredictable. It was reported that every year millions of people die because of fine particles when exposing to air pollution and other millions die from water-born diseases. Management and monitoring of air and water pollution by using GIS technology is an effective method. The measured data can be obtained continuously, quickly and accurately at stations in any regions even with complex terrain. This helps reduce the required number of employees, manage automatically and continuously a large number of data.Ngày nay nhu cầu về một môi trường sống xanh, sạch đang gia tăng, với sự bùng nổ của phát triển kinh tế - xã hội và trình độ dân trí.

Synthesis of Flower-like Silver Nanostructures on Silicon and Their Application in Surface-enhanced Raman Scattering

To enhance the intensity of surface-enhanced Raman scattering (SERS), production of metal nanostructures with sharp points, lying side by side at the nanometer level plays an extremely important role. In this paper, we report on a manufacturing process in which the silver nanoparticles with the flower-like shape have been fabricated. Such silver nanoparticles have been fabricated by chemical deposition of silver particles on silicon wafers, using a solution of hydrofluoric acid (HF), silver nitrate (AgNO3) and ascorbic acid (AsA) in water, at room temperature. During the manufacturing we found that only when the concentrations of AgNO3 and AsA are appropriate, the flower-like silver nanoparticles will form. Note that while other authors mainly made flower-like silver nanoparticles in the form of suspensions, we have created flower-like silver nanoparticles with cabbage-shape on a silicon surface. The ensembles of flower-like silver nanoparticles above were used as SERS substrates to detect crystal violet (CV) in low concentrations and good results were obtained
