Nghiên cứu tập trung vào đánh giá hiện trạng và biến động diện tích, năng suất, mức độ thâm canh và hiệu quả kinh tế của các loại hình sử dụng đất lúa tại Đồng bằng sông Hồng. Nghiên cứu được thực hiện bằng các phương pháp thu thập và kế thừa tài liệu, điều tra nông hộ, đánh giá hiệu quả kinh tế của quá trình sử dụng đất. Kết quả nghiên cứu cho thấy, năm 2018 toàn vùng có 588.357 ha, chiếm 15,04% diện tích đất lúa cả nước. Trong 10 năm (2010 - 2018), diện tích đất lúa của vùng giảm 31.589 ha, với tốc độ giảm bình quân 3.948,6 ha/năm. Hầu hết các tỉnh (10/11 tỉnh) đều giảm diện tích đất lúa (trừ tỉnh Quảng Ninh), bình quân giảm từ 143 – 800 ha/năm, trong đó thành phố Hà Nội giảm nhiều nhất. Mức độ thâm canh lúa cao, hệ số sử dụng đất lúa thay đổi từ 1,85 lần (2010) đến 1,77 lần (2018). Năng suất lúa toàn vùng giai đoạn 2010 - 2012 tăng và từ 2012 - 2018 có dấu hiệu giảm. LUT5 có hiệu quả kinh tế cao nhất, hiệu quả thấp nhất là LUT2.

AbstractIntroductionAfrican swine fever (ASF) was officially reported in Vietnam in February 2019 and spread across the whole country, affecting all 63 provinces and cities.Material and MethodsIn this study, ASF virus (ASFV) VN/Pig/HaNam/2019 (VN/Pig/HN/19) strain was isolated in primary porcine alveolar macrophage (PAM) cells from a sample originating from an outbreak farm in Vietnam’s Red River Delta region. The isolate was characterised using the haemadsorption (HAD) test, real-time PCR, and sequencing. The activity of antimicrobial feed products was evaluated via a contaminated ASFV feed assay.ResultsPhylogenetic analysis of the viral p72 and EP402R genes placed VN/Pig/HN/19 in genotype II and serogroup 8 and related it closely to Eastern European and Chinese strains. Infectious titres of the virus propagated in primary PAMs were 106 HAD50/ml. Our study reports the activity against ASFV VN/Pig/HN/19 strain of antimicrobial Sal CURB RM E Liquid, F2 Dry and K2 Liquid. Our feed assay findings suggest that the antimicrobial RM E Liquid has a strong effect against ASFV replication. These results suggest that among the Sal CURB products, the antimicrobial RM E Liquid may have the most potential as a mitigant feed additive for ASFV infection. Therefore, further studies on the use of antimicrobial Sal CURB RM E Liquid in vivo are required.ConclusionsOur study demonstrates the threat of ASFV and emphasises the need to control and eradicate it in Vietnam by multiple measures.

Gas Emissions

Livestock farming is a major source of greenhouse gas and ammonia emissions. In this study, we estimate methane, nitrous oxide and ammonia emission from livestock sector in the Red River Delta region from 2000 to 2015 and provide a projection to 2030 using IPCC 2006 methodologies with the integration of local emission factors and provincial statistic livestock database. Methane, nitrous oxide and ammonia emissions from livestock farming in the Red River Delta in 2030 are estimated at 132 kt, 8.3 kt and 34.2 kt, respectively. Total global warming potential is estimated at 5.9 MtCO2eq in 2030 and accounts for 33% of projected greenhouse gas emissions from livestock in Vietnam. Pig farming is responsible for half of both greenhouse gases and ammonia emissions in the Red River Delta region. Cattle is another major livestock responsible for greenhouse gas emissions and poultry is one that is responsible for ammonia emissions. Hanoi contributes for the largest emissions in the region in 2015 but will be surpassed by other provinces in Vietnam by 2030.

Investment Environment

Before deciding to invest in a certain locality, investors always consider the investment environment or competitiveness of the localities and tend to invest in the localities with the highest scores and high rankings on provincial competitiveness in the region. This study focuses on analyzing and evaluating the competitiveness of Nam Dinh province in comparison with other provinces in the Red River Delta. The results show that although Nam Dinh has made a lot of progress in improving the investment environment and increasing the PCI score, the PCI ranking is still not high, even worse than many other provinces in the region. In order to contribute to improving the province's competitiveness in the coming time, this study has proposed a number of possible solutions.
