Then but I don't have the more recent data up it's important we import billions of dollars love seafood every year and eighty percent over that is aquaculture product so aquaculture very big item internationally two major item in international trade welcome back to that latter point be burns aquaculture take place usually where there's water good thing to have but that doesn't mean that even where there's lots of water that there's no competing uses for that water this is in north Vietnamese are areas that you used to be in rice production and the rice farmer said we can make more money raising shrimp and exporting the shroud for foreign exchange earnings begins making more money that's great we're not going rights for domestic markets
were producing a product that's going into international trade there's conflict between uses love above land and water resources even when they are relatively abundant and in the sense here above water points there's competition we make choices when we invest in one activity or another sometimes the South Vietnam Mekong Delta sometimes water is to abundant the blue area here shows what would happen with 1-meter sea level rise as I'm sure you're aware with global climate change ready things happening one of them is the gradual elevation sea level and this is an area where in part in the world not the only one Louisiana is another where in delta's exist and other very low-lying areas and you're likely to have a in so a sea level rise inundating areas that are currently used in production this is taken from a airplane north coast of Java on you can see that this is an area
that also if you had a one meter sea level rise sea levels going to be words that was going to be way up in here that's not much elevation involved in and so much of the area involved in coastal aquaculture is quite likely to have a serious the struggles as we move into global climate change inseam level rise so bail ability or too much water are issues %uh sometimes we have actually moved aquaculture operations away from in this case which room away from the coastline because I've disease problems and other issues and moved hyper saline water in trucks in Thailand hundreds Goji Actives of climbers away from the Scotland a growing shrimp in the interior of Thailand it's now banned by the government but what the government says doesn't always work when you have a lot of money to be made by doing something like raising shrimp what happens is as you have brought the saline water up up to raise the shrimp you have so on eyes the soil where that used to be rice fields and their arms rice varieties their salt tolerant but you have long-term impact on.
