Môi trường - Lecture 4: Climate change, environment issues and impacts
- People living along in low deltas and coastal belts.
- Migrant and poor labor residents in cities
- Ethnic minority, women, children and elderly.
The poor are also most at risk because they have little diversity in their income sources. They lack the resources and ability to invest to absorb climate related risks, or to recover from extreme events

Social –economic vulnerability (poor infrastructure, lack of insurance system, credit, knowledge, poor management, irigation,ect) Who are vulnerable?- People living along in low deltas and coastal belts.- Migrant and poor labor residents in cities- Ethnic minority, women, children and elderly.The poor are also most at risk because they have little diversity in their income sources. They lack the resources and ability to invest to absorb climate related risks, or to recover from extreme eventsXayaburi dam and Don Sahong being constructed in Lower Mekong river in LaosWater Conversion Project along the Mekongs DiscussionWatch the video and review the reading “Are Vietnam’s Delta dying?”Discussion : How the Mekong river delta become???

Thi Vai River pollution Vedan Company discharging untreated waste water into the Thi Vai river (5000m3 /day in 10 years), making the river dead.Nicotex Thanh Thai company dumped untreated toxic waste poisoning the land in Cam Thuy district, Thanh Hoa provinceThe bauxite-alumina project in the Central Highlands => The"red" dust waste causing Air pullution, Water Pollution, fishery pollution (the bauxite site to dump the red sludge, seriously harmful to the heath of a population of 30 million and causes agricultural damage to the highland farms)Mining Formosa and poison oceanFormosa apologizes for polluting the ocean but continues to burry the hazardous waste in forest “Everyone has the right to live in a clean environment, and the obligation for environmental protection” (Article 43, Constitution 2013).Very few guildlines/ document under laws mentions how to control the water polution.The Nicotex company was fined only VND 421 million (USD20,000)Vedan company was fined only VND 267 million ( USD 13,000)Formosa compensate 500 million USD for the damages.No case of pulution is brought to the court Pollution and HeathOnly about 60% of the Vietnamese people have access to water that is clean and drinkable. Many water supply systems in South East & HCM is under standard80% of diseases in Vietnam are caused by polluted water resources (MONRE) such as cholera, giardiasis, cancer, miscarry, inborn disable, infection (women), The red sludge puts health and human lives at risk of being lost or harmed due to air, water and fish pollution. The medical statistics prove that prolonged toxicity may cause encephalopathy, osteoporosis, anemia, and possibly Parkinson diseases. Every day, more projects Coal Thermal Plants (Vinh Tan, Long An, Hau Giang)Steel Plant (Hoa Sen Group)Paper Mill Plant (Lee & Man)Industrial Zones (hundred of factories)Forest and land problemForests in mountainous areas are being chopped down for logs Coastal mangrove forests are being cleared for fish farmsLand confiscationsFrom 2001 to 2009: - 1,116,000 ha of agricultural land were taken for investment projects. - Every year, 124,000 ha of agricultural land are transferred to development projects. - More than 50% of confiscated land were at the most densely populated areas of the Red River delta and Southeast and Mekong deltaImpacts of land confiscation (MARD survey):Land confiscations affected badly 627,000 peasant households, 950,000 laborers & 2,5 million people.53% of households had incomes reduced.only 13% of households were able to move to new jobs87% fell into unstable employment or uncertainty in livelihoodsLandless peasants have been on increase and found difficulties in seeking new jobsEvery one hectare of rice land confiscated, 15 to 20 rural laborers will become unemployment Think for next step Environment in transitionPeople and environment in climate change context New form of poverty, who are the poor, the vulnerable and the new poor?New “benefit group”Political agendaWho has the power ?
