Saline intrusion risk to agricultural land in Can Tho city under climate change scenarios

Saline intrusion is posing growing challenges to agricultural production in the lower Hau River region, where agricultural land use is closely linked to water availability. A study conducted in the former Soc Trang province, now part of Can Tho city, assessed saline intrusion risk to agricultural land use in 2024 under the RCP 4.5 and RCP 8.5 climate change scenarios for 2030 and 2050. The results show that the area of rice cultivation affected by higher salinity levels tends to increase, providing an additional scientific basis for land use planning and the selection of appropriate adaptation-oriented farming systems.
