Production adapts to climate change

Not long ago, due to unusual weather changes and a large temperature difference, dozens of durian trees of Mr. Nguyen Duy Thiem's ​​family (Doan Ket village, Dak Ngok commune) lost their leaves, not ensuring fruit growth in the new crop. To overcome this situation, his family had to remove the first flowers of the season to nourish the trees. In addition, Mr. Thiem invested in installing a misting and drip irrigation system to provide enough water for the trees to grow in the current unusually hot weather.

According to Mr. Thiem's ​​experience, if using the traditional irrigation method with a conventional sprinkler system, it is very easy to affect the flower buds and young shoots of the tree. With the drip irrigation method using a root sprinkler system like his family is applying, the amount of water is evenly distributed to the roots and seeps down to the area where the tree roots are, saving water for each irrigation and maintaining stable humidity. At the same time, direct irrigation by the drip method also limits dependence on water sources, because it is possible to take advantage of water from the system of small ponds and lakes.

Similar to Mr. Thiem's ​​family, after a period of technical research, Mr. Vi Dak Uyn's family in Thanh Xuan village, Dak Ngok commune also invested in installing a drip irrigation system on an area of ​​1.3 hectares of coffee intercropped with durian during the basic construction period. To improve the efficiency of land exploitation, he also planted passion fruit trees with the motto "taking short-term to nurture long-term".

“I have been applying this model for over a year now and have found it to be very effective. Specifically, with my family’s garden, the system can water all three types of plants: coffee, durian and passion fruit. Moreover, I can water at different times, and am less affected by the irrigation schedules of surrounding households. Thereby, I can ensure that the garden grows well and save on investment costs and plant care in the dry season,” Uyn shared.

Entering the dry season this year, Dak Ha district has a total area of ​​over 25,000 hectares of coffee and fruit trees that need a lot of irrigation water. Of which, nearly 500 hectares of crops are likely to suffer from drought and lack of irrigation water at the end of the dry season. Therefore, in addition to the management and effective exploitation of reservoirs and dams, irrigation canal systems, units, localities and businesses in the area have proactively implemented water-saving irrigation measures.

At the Kon K'loc village coffee model field, Dak Mar commune of 704 Coffee Company Limited, to ensure irrigation water for nearly 80 hectares of coffee of ethnic minority workers during the dry season, the unit has invested in a large-capacity dynamic pump system to lead water from the Kon K'loc irrigation dam to the central reservoir of the production area with a length of nearly 2 km. At the same time, a 3-phase power line was installed for households to apply water-saving irrigation measures through the sprinkler system, both saving production costs and ensuring uniform regulation of irrigation water for the entire area.

To ensure production adaptation to climate change, Dak Ha district has directed units and localities to strengthen coordination in regulating irrigation water sources, ensuring science and efficiency; taking advantage of water from ponds, lakes, and small streams to reduce water pressure for the level I canal system. In addition, reviewing and mobilizing people to invest in installing water-saving irrigation systems, irrigation pumps combined with the use of biological products to improve productivity and product quality.

With the forecast of a prolonged dry season, the risk of local droughts remains high. In addition to doing a good job of state management in managing and exploiting irrigation works, farmers proactively learning and investing in applying new farming and production methods to adapt to climate change is a positive factor to bring about economic efficiency in agricultural cultivation in the dry season. At the same time, it helps people stabilize production, improve productivity and quality of agricultural products in the face of extreme climate change like today.
