Tran Thi Kim Lien reports on the threats to the communities of her childhood.
In one study in my hometown – a mountainous area in North Central Region of Vietnam, we considered Huong Lam commune – one of the vulnerable areas of climate change in Ha Tinh province. The commune is home to 6,673 people in 1,636 households with an average population density of 400 people/km2. Their main livelihood activities are agriculture, small industries, trades and services. Our study found that this commune faces risk from floods, droughts, cold and storms.
The most immediate impact of drought is a reduction and even loss in crop production (paddy rice, peanut, maize, etc.) due to inadequate and poorly distributed rainfall. Another severe impact of droughts is water shortages (Overseas Development Institute, 1997 PDF). Lower pasture production from droughts may also decrease fodder supplies. With little land available, the people cannot reduce risk through diversification (Beckman, 2011). The unusual dry conditions since the end of 2015 (allied with El Niño) have led to severe droughts around the country (IFRC, 2016).
The worst agricultural losses are from floods that arrive with typhoons. Floods destroy both standing crops (paddy rice and fruit trees) and stored food. They also increase fungal infections that destroy seeds for the next planting. Floods of 2-3 days cause serious health problems for people (in particular, the disabled and elderly) who live in poor conditions with limited food sources, polluted water sources, and poor sanitation (Few, Ahern, Matthies, & Kovats, 2004 PDF).
The Vietnam Ministry of Natural Resources and Environment projects that medium emissions climate change scenarios (B2) will increase annual rainfall by 2-7 percent by 2100, with less rain in the dry season and more in the rainy season. Maximum daily rainfall may double in the North Central zones (including in Ha Tinh). Typhoons can uproot crops, damage trees, and destroy housing and animal shelters (Few, Ahern, Matthies, & Kovats, 2004). Climate change will change the intensity, frequency and (un)predictability of storms. In Ha Tinh, storms that normally occur from August to October are sometimes showing up in April, causing greater damage due to their unpredictable frequency and intensity.
The people of Huong Lam will not find it easy to adapt.
Tran Thi Kim Lien [email] holds Bachelors and Masters degrees in Forest Science and Management from Vietnam and Australia, respectively. After earning her first degree, she spent 13 years working in forestry and rural development in North Central Vietnam. Her Masters degree has widened her knowledge to include environmental management and climate change adaptation. She now focuses on helping local people understand their vulnerabilities and adapt to climate change.
