The agricultural sector restructures production

(VEN) - The farming sector is strongly affected by climate change and is also the cause of greenhouse gas emissions. Therefore, the government and relevant ministries have paid special attention to measures in response to climate change for this sector.

A number of new rice varieties can adapt to climate change

According to a preliminary assessment of the Department of Crop Production under the Ministry of Agriculture and Rural Development, due to the impact of climate change on the farming sector in Vietnam, total crop production could reduce by one to five percent by 2020.

According to the national scenario in terms of climate change, the country could witness “a sea-level rise of 30cm, temperature increases by 2-3 degrees Celsius and total average annual precipitation increases by five percent by 2050”. In addition, by 2100, the Mekong Delta granary could have poor crops, reaching 7.6 million tonnes per year, equal to 40.5 percent of total rice production in the region. Moreover, the northwest and northeast, and the Central Highlands have faced with an increasing risk of drought. In particular, climate change has changed living conditions of the organisms, making an increase in epidemic diseases. According to the Department of Crop Production’s statistics, in recent three years, brown plant hoppers had caused a significant decline in rice production in the Mekong Delta. In terms of the Red River Delta, pestilent insects had made a decline in rice productivity by 30-70 percent. 

Department of Crop Production Deputy Director Pham Dong Quang said, “Climate change has strong impacts on the farming sector, causing a decline in farming land and an increase in pestilent insects. Therefore, it is necessary to agree measures in response to climate change”.

According to Pham Dong Quang, although the Ministry of Agriculture and Rural Development had actively increased production value and productivity of the farming sector by 20 percent and reduced gas emissions by 20 percent, the farming sector should implement the restructuring. 

It is necessary to implement farming methods and new agricultural production measures, contributing to ensuring food security and income for farmers.

In terms of solutions, it is necessary to select new varieties with high adaptability, improve efficiency of fertilizer use and change farming methods. In addition, solutions to reduce erosion, increase organic sources and reduce gas emissions into the environment are needed.

The farming sector has focused on investing in variety selection, contributing to finding new varieties. According to Pham Dong Quang, the Department of Crop Production selected a new rice variety adapting to flooding conditions, such as U17 and U21. In addition, some rice varieties were put into the test in the Mekong Delta, such as IR66876 and IR07F102.

Department of Crop Production Deputy Director Pham Dong Quang said that to respond effectively to climate change, it was necessary to promote rice growing and shrimp breeding models. The Mekong Delta region currently has more than 120,000 hectares of agricultural land to grow rice and breed shrimp. The fact proved that these models well adapted to climate change./.
