On November 17th 2017, in the Ca Mau city, the Directorate of Water Resources (Ministry of Agriculture and Rural Development – MARD) together with the Ca Mau Provincial People’s Committee, the Asian Disaster Preparedness Center, the Norway Geological Institute and the Vietnam Institute of Geosciences and Mineral Resources organized the workshop on “Impacts of land subsidence on water resources infrastructures”. There were about 100 participants from different units, such as the Vietnamese Government Administration Office, MARD, Ministry of Science and Technology, Ministry of Construction, representatives from provinces in the Vietnamese Mekong Delta, universities, research institutes, international organization (World Bank, French Development Agency, the Japan International Cooperation Agency and Deutsche Gesellschaft für Internationale Zusammenarbeit, GmbH) and mass media units (https://www.mard.gov.vn/Pages/hoi-thao-khoa-hoc-anh-huong-cua-sut-lun-dat-den-he-thong-cong-trinh-thuy-loi.aspx)
The participants of the workshop discussed issues related to land subsidence in the Ca Mau Peninsula, the main driving forces and possible solutions. The surface water resources scarcity is considered to be the main reason leading to the fact that local people over-used groundwater resources mostly for domestic consumption, cropping irrigation and industry causing land subsidence. Other driving forces are also mentioned, including natural compaction / consolidation processes, and infrastructure loading.
The impacts from land subsidence, climate change, especially sea level rise, and socio-economic development caused serious drought, saline intrusion and mangrove forest degradation in the coastal areas of the Ca Mau Peninsula. These factors have been threatening the natural ecosystem, infrastructure, urban inundation which could create significant affects to the livelihoods of people in the region.
In the workshop, representative of the Rise and Fall project presented main findings on the groundwater resources governance in coastal plains of the Vietnamese Mekong Delta (with the specific case study of the Soc Trang province). In addition, land subsidence issue initial results are also briefly mentioned and informed in the workshop.
