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.
