| Climate variation and change | Typhoons/severe tropical storms: Typhoon Linda in 1997, Durian in 2006, storm in 2008, recently Pakhar storm on 01/4/2012.
Storm surges/flooding: As the flood drainage area of Long Xuyen Quadrangle (including the provinces of Kien Giang, An Giang, Can Tho), there are five major floods in 1994, 1996, and 3 consecutive floods from 2000-2002, which included a historic flood in 2000, where nearly 15 thousand hectares of agricultural land was damaged, more than 314 km of rural roads were damaged, 16 people died, and material damage estimated at over 317 billion.

| Other natural threats and hazards | Coastal erosion: Riverbank erosion occurs most channels such as Cai San channel, Rach Gia - Ha Tien channel, etc. Shoreline erosion occurs at the sea dike, in areas such as Rach Gia - Ha Tien, An Bien - An Minh, Hon Dat, etc.
Sedimentation: Due to the relatively stable shoreline, the trend of sedimentation prevailed. As a result, it enabled tidal mangrove plants to grow, mainly Avicennia, Rhizophora, Su, Vet as sediment at Xeo Quao (bordering An Bien - An Minh District)
Landslides: There was a landslide dike embankment at Ha Tien park which eroded a section of about 20m long, 5m wide. Landslides are possible due to narrow riverbed and flow changes. |
| Man-made threats and hazards | Domestic/household sewage: Domestic waste water in urban areas in Kien Giang are organic pollutants, nutrient pollution of water resources in many areas and especially heavy microbial contamination with BOD5 = 20-937 mg/l, N total = 3.5 to 165 mg/l, P total = 0.3 to 47 mg/l and total coliform = 24x103 - 24x106 MPN/100ml. Urban domestic sewage was polluting locally at several places by heavy metals (Fe, Cd) but it is not at an alarming rate. This is one of the major sources of pollution for surface water environment and likely to cause widespread epidemics.
Domestic garbage/solid waste: In urban areas of Kien Giang province, solid waste arises mainly from households, markets, construction waste, hospitals, medical facilities, industrial operations, bodies, offices. This waste includes vegetables, fruits, tubers and damage excess, food, paper, plastics, wood, glass, metals, tires, electronics, home appliances, steel, concrete, brick , plaster, metal injection, bottles containing drugs, drugs in expired, etc. According to experts' estimates, the urban population every day generates about 0.6 to 0.8 kg/person/day of municipal waste, so the urban population in 2007 as we can estimate the total domestic solid waste generated in urban areas in Kien Giang is 354,514.4 kg/day or 354.5 tons/day. In particular, it is 170.75 tons/day (0.8 kg/person / day for the urban population are 213,447 people) and other urban centers are 183.75 tons/day (0.8 kg/person/day for the urban population are 229,696 people) in Rach Gia city. According to the Urban Construction Company and waste management activities, the composition of household waste at present rates of easily decomposable organic waste accounts for a majority of about 80 %, paper and plastic bags account for about 7 %, other types accounted for 13 %. CHCs and district clinics with 16 beds total in 2007 was 3,510 beds. So, estimated load of medical waste for 3,510 Kien Giang scale discharged daily bed is 7371 ÷ 9,828 kg /day. In particular, hazardous waste accounts for about 20 %, ie 1,474.2 ÷ 1965.6 kg/day, municipal waste accounts for 80 % ie about 5,896.8 ÷ 7.862.4 kg/day.
Industrial and hazardous waste: Hazardous waste generated in the province is still a small percentage, which is essentially no risk of solid waste harm.
Deforestation/land use: In 2012, the total number of violations of is 80 cases (10 cases decreased over the same period); has handled 78 cases (the remaining 2 cases) with total fines for administrative violations 205.3 million VND.
Unsustainable aquaculture practices: Aquaculture cages are spontaneous, unplanned
Overexploitation/destructive use of habitats (mangroves; coral reefs; seagrass): Ham Ninh Waters, the south of Phu Quoc island are abused the most, followed by shallow coastal waters stretching over 100 km limit from An Minh to Ha Tien..Regional conservation coral and sea grass Phu Quoc area is 16,545 ha and adjacent areas developed on 10,000 hectares are seriously compromised by the active exploitation of marine resources, tourism threatens the ecological environment sea . The raking shore facilitie, real diving situation, crab traps, etc is destroying sea grass, which feed the Dugong. Seagrass beds are also breeding grounds for many marine species that are endemic.
Polluted river discharges: Average per day, the system of rivers and canals in the area suffered about 10,000 m3 of waste water from the production facilities, in which 80% of untreated wastewater comes from seafood processing factories for export and domestic consumption.
Salt water intrusion: Long Xuyen quadrangle area and Ca Mau Peninsula Area have incidences of salt intrusion deeply in the interior that has caused damage to agriculture and fisheries, and affected directly the lives and incomes of local people.
