Quang Ninh: Being a mountainous and coastal province, with more than 80% of its area being made up of mountains and hills, Quảng Ninh's climate not only stands for symbolic of the climate in the North Vietnam; featuring all four seasons but also owns some features of a coastal mountainous province. The climate in some islands in Cô Tô and Vân Đồn Districts typifies ocean one. The average heat radiating during a year is 115.4 Kcal/sq. cm. The average temperature is over 21?C, while the average humidity is 84%. Annual rainfall totals between 1,700 and 2,400mm, and there can be between 90 to 170 rainy days in a year. These are mainly concentrated in the summer (more than 85%), and especially in the months of July and August. In winter, rainfall only reaches between 150 and 400mm. The areas for aquaculture in Quang Ninh is calculated to be about 20.000 ha. The labour force in aquaculture is estimated about 19.456, female labour account for 37,4%.

In Quang Ninh, the aquaculture capacity is widely known for its diversity and high production. The aquaculture production in 2011 was estimated at 31.266 tons including: 7.000 tons shrim (tiger prawn and white-leg shrimp); 7.240 tons fresh water fish; 6.500 marine fish; 10.500 tons mollusk (Yelow clam, clam, otter…).Seed production: There are about 13 seeds produced company with the productivity at 500 million seeds (which 400 million seeds are shrimp, 100 million are fresh water fish). Quang Ninh has been suffered by climate change heavily. In 2009, the loss was estimated at 200 billion VND. At present, Quang Ninh has been organized for training session relating to understand the symptoms of Climate Change and help fisherman to change their occupation.

Nghe An: Being a large province in the central part of Vietnam that connects the North to the South, Nghe An shares its border with Thanh Hoa in the north, East Sea in the east, Laos in the west, and Ha Tinh in the south. Nghe An is located on the North East of Truong Son range, with complicated topography, divided by hills, mountains, rivers and streams slanting from North-West to South-East, mountainous and hilly lands cover 83% natural area of the whole province. The province is located in the tropical monsoon area, directly affected by the South West hot dry seasonal winds (during April- August) and the North East wet and cold seasonal winds (during November- March). The annual average temperature varies between 23ºC and 24ºC.

In Nghe An, the aquaculture production in 2011 was 39.800 tons (in which: 31.000 tons were produced in fresh water and the other 8.800 tons in brackish water and sea water). The size of aquaculture areas in 2011 was 22.500 ha (in fresh water: 20.500 ha; In brackish water and sea water: 2.000 ha). Seed production: + The fry fish production was 500 million fish (tilapia fry fish at 20 million). Shrimp seed production: 910 million seeds (the quantity of tiger prawn (Penaeus monodon) seed was 170 million shrimps and the quantity of white-leg shrimp seeds was 740 million). In brackish water and sea water, white-leg culture has become more and more popular than tiger prawn. While for mollusk, clam (yellow clam, short-necked clam, Ben Tre clam..) culture accounts for the biggest proportion (90%). While in fresh water, the traditional fish (carp, silver carp) have been raised. Nghe An has been suffered by climate change and the loss increased significantly. In 2008, the loss was calculated at 8 billion VND; In 2009 and 2010, the figure was 40 billion and 42 billion, respectively; In 2011, it was estimated more than 45 billion. At present, World Bank has been funding Nghe An for two projects relating to climate change involving infrastructure improvement and sustainable development.

Hai Phong:Hai Phong is a coastal city located at the mouth of the Cam River, in Vietnam's northeastern coastal area, 120 km east of Hanoi. It has a total natural area of 152,318.49ha (2001).

Bach Long Vi island, located in the Gulf, is also administered as part of the city. The city is located in a convenient position for transportation to domestic provinces, and international networks via road network, railway, sea routes, inland waterway and air.

In aquaculture of brackish water, the productivity of tiger prawn is 760kg/ha, of brackish fish is 1.260kg/ha; of white-leg shrimp is 11.6 tons/ha. In fresh water: traditional fish (carp, silver carp, tilapia, butter fish) productivity at 3,69 tons/ha. Marine fish productivity at 296,25 kg per cage. Hai Phong also has been suffered by climate change, sea level rose 20cm over 50 years, the average temperature has been increased, storms happens frequently… The loss in 2010 was estimated hundreds of billions VND. At present, Hai Phong is organizing some programs relating to climate change adapting such as: Recovery coastal mangroves, building adapting plan for fishery, forecast system improvement…v.v
