Organisational Baseline Study: Overview report for Ma CSV, Vietnam (VN01)
According to the data provided by Yen Bai Statistics Department (YSD), the total area of Yen Bai about 668,628 ha, of which 87.5% (585,089 ha) are agricultural land. Most of the province’s agricultural lands are sloping. The province shares the common features of the North-western Vietnam: terrain is complicated and are strongly fragmented by mountain and stream systems; climate is tropical and with different climatic sub- regions. Over 70% of the population (over 70%) are agricultural.
Yen Binh district locates in the south of Yen Bai province, with the total area of 77,262 ha, and is diverse and rich in natural resources.
Having diverse agricultural production activities (including crop, livestock, aquaculture and forestry) and sharing the common features with the province, Ma village has been facing important challenges caused by natural resource degradation, environmental pollution and climate variability. On the other hand, there are also great potentials for this village to develop sustainable and climate smart livelihoods and agriculture. Ma village, Vinh Kien commune, Yen Binh district, Yen Bai province has therefore been selected to be a site for building Climate Smart Villages (CSV) under the CGIAR Program “Climate Change, Agriculture and Food Security (CCAFS).
An organization baseline survey, was therefore conducted as part of the baseline effort for this village, which consists of three components – household survey, village study and organizational survey.
The objectives of this organization baseline study (OBS) include:
- Provide indicators to allow us to monitor changes in behaviours and practices of relevant local organizations over time;
- Understand the current status of provision of information/services at the local level that informs farmers’ decision making about their livelihood strategies in response to climate change.
To gather necessary information, we conducted survey of organizations of which activities covered a wide range in all the aspects: natural resources management, environment and climate change, agricultural production, agricultural product processing and input supplying. The list of these organization is presented in Table 1
Active disturbance rejection control-based anti-coupling method for conical magnetic bearings
Conical-shape magnetic bearings are currently a potential candidate for various magnetic force-supported applications due to their unique geometric nature reducing the number of required active magnets. However, the bearing structure places control-engineering related problems in view of underactuated and coupling phenomena. The paper proposes an Adaptive Disturbance Rejection Control (ADRC) for solving the above-mentioned problem in the conical magnetic bearing. At first, virtual current controls are identified to decouple the electrical sub-system, then the active disturbance rejection control is employed to eliminate coupling effects owing to rotational motions. Comprehensive simulations are provided to illustrate the control ability
Situation Analysis and Needs Assessment Report for Ma Village and Yan Bai Province, Vietnam
Ma village is one of the 15 villages of Vinh Kien commune, Yen Binh district, Yen Bai province in the
northern mountainous region of Viet Nam. Ma village was selected as a site for the Climate Smart Village
(CSV) development under the CGIAR Research Program on Climate Change, Agriculture and Food Security
(CCAFS). It has a topography, landscape and climate conditions representing most in the region and faces
increasing challenges caused by climate variability, natural resources degradation, and environmental
pollution.
The village’s current production systems have low sustainability and profits. Maize and cassava are largely
produced in dominant monoculture systems on sloping lands representing most of the village’s total arable
lands, while rice is planted in a small area. Slash and burn practices are used largely in sloping lands, while
unbalanced fertilizer levels (often with too much nitrogen) are applied for all the crops, and integrated pest
management is yet to be promoted. All these have caused high intensity soil erosion, land degradation,
and GHG emission. In addition, improper waste management, particularly from cassava, has resulted in
severe water pollution in all river and lake systems.
Organizations are present to support Ma village and the province in the areas of agriculture, forestry, food
security, and climate change adaptation and mitigation. However, coordination between organizations
remains poor. The local systems currently do not have the capacity to solve the multiple problems in
the village. Human and financial resources. Inadequate. Support from CCAFS in important to help the
village address the increasing problems caused by climate change, water pollution, soil erosion, and land
degradation
Village Baseline Study – Site Analysis Report for My Loi, Ky Anh district, Ha Tinh province – Viet Nam
Data collection for the Village Baseline Study (VBS) of My Loi village in the CCAFS
benchmark site of central Viet Nam took place on 17- 19 October 2014. Focus group
discussions were conducted separately for 45 men and 45 women villagers.. The VBS had
three main topics: map of (1) community resources, (2) organizational landscapes, and (3)
information networks. A seminar was held in December 2014 to seek participants’ feedback.
My Loi village has experienced multiple extreme weather events (temperature and water
stresses, storms and typhoons) throughout the years. The main constraints for agricultural
development and livelihoods are limited water resources and poor conditions of irrigation
systems, which are challenges to improving the agricultural production situation. Moreover,
sand and rock mining have caused water pollution, erosion on riverbanks and loss of
farmland area. Another constraint is marketing, as villagers are not aware of any organization
involved in finding outlets for agricultural products. The potentials for developing innovative
climate-smart solutions in the village are several: farmers have experiences and are interested
in trying new varieties and adjusting farming calendars to improve the situation. Livestock
expansion and agroforests/reforestation hold opportunities for improving household incomes.
Furthermore, at least half of the organisations identified in the region are working to address
food security issues
Village Baseline Study – Site Analysis Report Ma village-Yen Binh district, Vietnam
Ma village, Vinh Kien commune, Yen Binh district, Yen Bai province has been
selected to be one of Climate Smart Villages (CSVs) under the CGIAR Research Program on
Climate Change, Agriculture and Food Security (CCAFS) in Southeast Asia. The village
baseline survey (VBS) of Ma village, was therefore conducted as part of the baseline effort.
This VBS aimed to provide baseline information at the village level about some basic
indicators of natural resource utilization, organizational landscapes, and information
networks for weather and agricultural information, which can be compared across sites and
monitored over time. The study was conducted using the method developed and provided by
CCAFS. The study’s findings show that Ma Village is rich and diverse in natural resources.
There are three main resources of vital importance for the local people livelihoods, namely
farmland, forest and water resources. However, improper exploitation and management have
caused negative impacts on these resources. As mentioned by farmers, in the past, farmland
of the village used to be very fertile, but has now become severely degraded due to overexploitation
and improper management. Regarding forest resources: before 1980s, natural
forests existed in large areas and consisted of valuable timber and wild animals. Today, much
of the forest area has been converted to production forests or to food crop production land.
Water resources, including lakes, rivers and streams have been severely polluted with
pollutants from processing cassava, wood and also from animal husbandry and crop
production. Degradation of water, farmland and forest resources are causing increasing
challenges to agricultural production and also to other human activities. Results of farmer
group discussions also demonstrate that there are 34 organizations operating in the village.
Most of them are governmental. Very few are private or non-governmental organizations.
The number of organizations involving in food security accounts for nearly 50%, the figure
for those involving food crisis is 41.6% and in natural resources management is 25%. Those
organizations working in food security and food crisis focus mainly on providing support
(financial, seed and agricultural inputs) to local farmers to implement some production
activities. Insufficient attention and input spent for sustainable development by these 34
organizations, especially those working in the area of natural resources management, could
be one of the main reasons for the degradation and erosion of natural resources. There was no
activity supporting Ma Village to develop production systems which can respond well to
climate change. The study findings however show that local people are very flexible and
creative, especially in exploitation of information. Among media channels, television is the
most popular. Nevertheless, organizations, in particular, extension networks, Farmers’ Union,
local authorities, etc., also have an important role in information dissemination. Exploitation
of information from the internet and mobile phones has also been given attention, but mostly
by young people only
Training of trainers (TOTs) and farmers (TOFs) on cattle and pig feed technologies in Main Son district, Son La province
A preliminary study to establish the transfected CHO cell lines which highly express Trastuzumab - A biosimilar product of Herceptin
Human epidermal growth factor receptor 2 (HER2) has been identified as a molecular target for breast cancer therapy, such as Trastuzumab (Herceptin®). This has been shown to improve patient survival substantially. The current study is aiming to locally produce an anti-HER2 monoclonal antibody (named Trastuzumab) which has an equivalent biological properties in comparison with the original version, Herceptin®). In silico design and construction of recombinant vectors, as well as the establishment of transfected cell lines with high expression of Trastuzumab were performed. Based on the protein sequences obtained from the Drugbank, the DNA sequences encoding for the light chain (Tras-Lc) and heavy chain (Tras-Hc) of Trastuzumab were optimized and integrated into pNanogen-Hygro and pNanogen-Puro vectors, respectively. The Neon Transfection System was used to co-transfect the pNanogen-Tras-Lc-Hygro and pNanogen-Tras-Hc-Puro constructs into CHO cells. Different co-transfected single-cell-colonies selected on media supplemented with hygromycin and puromycin were used for ELISA and SDS-PAGE assays to identify the CHO cell lines which highly express Trastuzumab. Based on the present results, 30μg of both constructs were suitable for DNA co-transfection. After 07 days of culture, the highest amount of Trastuzumab (561 µg/ml) was obtained from the H06LD68 cell line
CSA: Thá»±c hĂ nh nĂ´ng nghiệp thĂ´ng minh vá»›i khĂ háşu ở Việt Nam
During the last five years, Vietnam has been one of the countries most affected by climate change. Severe typhoons, flooding, cold spells, salinity intrusion, and drought have affected agriculture production across the country, from upland to lowland regions. Fortunately for Vietnam, continuous work in developing climate-smart agriculture has been occurring in research organizations and among innovative farmers and entrepreneurs. Application of various CSA practices and technologies to adapt to the impact of climate change in agriculture production have been expanding. However, there is a need to accelerate the scaling process of these practices and technologies in order to ensure growth of agriculture production and food security, increase income of farmers, make farming climate resilient, and contribute to global climate change mitigation. This book aims to provide basic information to researchers, managers, and technicians and extentionists at different levels on what CSA practices and technologies can be up scaled in different locations in Vietnam
TextANIMAR: Text-based 3D Animal Fine-Grained Retrieval
3D object retrieval is an important yet challenging task, which has drawn
more and more attention in recent years. While existing approaches have made
strides in addressing this issue, they are often limited to restricted settings
such as image and sketch queries, which are often unfriendly interactions for
common users. In order to overcome these limitations, this paper presents a
novel SHREC challenge track focusing on text-based fine-grained retrieval of 3D
animal models. Unlike previous SHREC challenge tracks, the proposed task is
considerably more challenging, requiring participants to develop innovative
approaches to tackle the problem of text-based retrieval. Despite the increased
difficulty, we believe that this task has the potential to drive useful
applications in practice and facilitate more intuitive interactions with 3D
objects. Five groups participated in our competition, submitting a total of 114
runs. While the results obtained in our competition are satisfactory, we note
that the challenges presented by this task are far from being fully solved. As
such, we provide insights into potential areas for future research and
improvements. We believe that we can help push the boundaries of 3D object
retrieval and facilitate more user-friendly interactions via vision-language
technologies.Comment: arXiv admin note: text overlap with arXiv:2304.0573
