Ecohealth research in Southeast Asia : past, present and the way forward
Ecohealth is a comprehensive approach to understanding health at its human, animal and environmental interface in a socio-ecological systems context. This approach was introduced widely in Southeast Asia (SEA) by the Canadian International Development Research Centre (IDRC) in the late 2000s. Aimed at addressing the problem of emerging infectious diseases (EIDs), numerous such projects and activities have been generated throughout the region. Ecohealth is increasingly converging with the One Health approach, as both movements emphasise a holistic understanding to health. We conducted a scoping review by considering all of the Ecohealth programmes, initiatives and projects that have been implemented in SEA since the introduction of the approach, and also gathered information from peer-reviewed literature. The objective of this paper is to review Ecohealth activities within SEA over the last 10 years to address the lessons learned, challenges faced and the way forward for Ecohealth in the region. Activities range from those focusing purely on capacity, projects focusing on research and projects covering both. Achievements to date include, for example, research contributing to the field of infectious diseases in relation to social ecological factors and associated urbanisation and agricultural intensification. Challenges remain at the project design and implementation level, in the available capacity and coordination to develop Ecohealth research teams in the countries, gauging teams' assimilation of Ecohealth's underlying tenets and their translation into sustainable disease prevention and control, as well as in the ability to scale up Ecohealth projects. We suggest that the way forward for Ecohealth should be from a regional perspective in terms of research, training and policy translation using Ecohealth in combination with the One Health approach
Validating a Scale for Measuring Preschool Teachers’ Competence in Promoting Children’s Language Development in Vietnam: An Exploratory Factor Analysis
The role of preschool teachers in supporting children’s language development is unquestionably substantial. To ensure the quality of preschool teachers’ performance in this specific task, various assessing instruments have been developed and justified in recent years. This study joins such efforts by investigating a new scale based on the “Framework for assessing preschool teacher competence in promoting children’s language development” proposed by a previous research. The scale’s psychometric properties are examined with a sample of 685 Vietnamese preschool teachers. The results supported the four-factor model suggested by the original authors and confirmed its reliability and validity. Finally, further usages of the scale are discussed
Lignin and Cellulose Extraction from Vietnam’s Rice Straw Using Ultrasound-Assisted Alkaline Treatment Method
The process of cellulose and lignin extraction from Vietnam’s rice straw without paraffin pretreatment was proposed to improve economic efficiency and reduce environmental pollution. Treatment of the rice straw with ultrasonic irradiation for 30 min increased yields of lignin separation from 72.8% to 84.7%. In addition, the extraction time was reduced from 2.5 h to 1.5 h when combined with ultrasonic irradiation for the same extraction yields. Results from modern analytical methods of FT-IR, SEM, EDX, TG-DTA, and GC-MS indicated that lignin obtained by ultrasound-assisted alkaline treatment method had a high purity and showed a higher molecular weight than that of lignin extracted from rice straw without ultrasonic irradiation. The lignin and cellulose which were extracted from rice straw showed higher thermal stability with 5% degradation at a temperature of over 230°C. The ultrasonic-assisted alkaline extraction method was recommended for lignin and cellulose extraction from Vietnam’s rice straw
MINIMIZING HEAVY METAL IN CRAFT-SETTLEMENT WASTEWATER BY SULFATE-REDUCING BACTERIA-DESULFOVIBRIO DESSULFURICANS

Dataset of Vietnamese students’ intention in respect of study abroad before and during COVID-19 pandemic
The Covid-19 Pandemic had completely disrupted the worldwide educational system. Many schools chose the online delivery mode for students in case learning losses incurred during social distance decree. However, as to these students who are currently in the study abroad planning stages, reached an intention crossroads, whether standing for certain unchanging decisions in study abroad destinations or changing swiftly due to the unexpected policies in quarantine. This case opened to interpretation, which was based on our e-survey since 3 May to 13 May 2020 with 397 responses covering a range of Vietnamese students. In this dataset, we focused on (i) Students’ Demographics; (ii) The previous intention of students to study abroad before and during the Covid-19 ravaged and (iii) Their intention afterwards
One Health-Ecohealth in Vietnam: The platform for networks for exchanging and fostering communication among researchers working in the field of integrated research
Ecohealth research to regionally address agriculture intensification impacts on health and the environment in Southeast Asia and China
Ecohealth Field Building Leadership Initiative is a regional operational
research network in Southeast Asia and China that
focuses on solving human health problems associated with agricultural
intensification. FBLI has 3 focus areas, namely research,
capacity building and knowledge translation. FBLI gathers
researchers, policy makers, community members and other stakeholders
from 4 focused countries (China, Indonesia, Thailand
and Vietnam). Here we describe the operational research component
that focuses on aspects of agriculture intensification on
health and the environment including animal waste from pig
production (Vietnam), dairy production (Indonesia), pesticide
use in vegetable production (China), and health risks in rubber
plantation (Thailand). Integrated approaches to the research
component including survey, participatory and cross-cutting
methods are discussed.
The research results from Vietnam and Indonesia showed
health and environmental impacts of manure management
options, in particular the biogas system and turning waste to
value. In Hanam of Vietnam, the health risks from biogas effluent
reuse include E. coli infection (19–22% of population
exposed) and G. lamblia infection (45–55% of population
exposed). In Pangalengan, Indonesia, the Ecohealth approach
was used to promote the production of medicinal worm and
casting biofertilizer from cow manure as an environmentallyfriendly
fertilizer alternative. In Chachoengsao Province of Thailand,
key findings include evidences for higher risk of vectorborne
diseases (dengue and chikungunya) in rubber plantation
areas as well as higher microbial and heavy metal contamination
of water and soil. In six villages of three townships in a County
of Yunnan Province, China, issues identified were lack of farmer
knowledge of pesticides, pesticide abuse, and ineffective policy
to reduce pesticide abuse. Pesticide contamination was recorded
from 6.1% to 12.7% of vegetables depending on sampling location
in the field or market. The findings from 4 countries illustrate
how Ecohealth research has been applied in health and agriculture and serve as basis for interventions for reduce health
and environmental risks
