Coastal saline acid sulphate soils with aquaculture and mangroves: a case study in Hochiminh city environs
نویسنده
چکیده
Hochiminh City environs have more than 45,000 ha of coastal plain soils which to be continued to the South by the great mangrove forest in Camau peninsula. How to protect and afforest mangroves successfully on these soils when using them also for aquaculture (shrimp, fish, crab, mollusc, etc.)? An answer to this question is now urgently needed. Dealing with the study on soil genesis/ geography and soil morphology/ characteristics, the paper indicated the identification/ classification of these soils and touched on the possibility to use them for the purposes of aquaculture, as well as of mangrove forest development. It is obvious that the results obtained through Hochiminh City environs case study can be applied to all the coastal soils in Camau peninsula of Vietnam and of the Humid Tropics.

Mangroves dwell at the land-ocean interface and are thus encroached upon by competing land-use at the coastal zone
Mangroves dwell at the land-ocean interface and are thus encroached upon by competing land use at the coastal zone. They are also subject to impacts from catchments developments. As a result, mangroves worldwide are having their extension changed (Spalding et al, 1997). Worldwide it is well accepted that mangrove extension is decreasing mostly due to conversion to other uses, in particular aqua...

Mangroves provide multiple benefits, from carbon storage and shoreline protection to food and energy for natural resource-dependent coastal communities. However, they are coming under increasing pressure from climate change, coastal development, and aquaculture. There is increasing need to better understand the changes mangroves face and whether these changes differ or are similar in different ...

The undervaluation of natural products and ecological services generated by mangrove ecosystems is a major driving force behind the conversion of this system into alternative uses. This trend of undervaluation is partly due to the difficulty involved in placing a monetary value on all relevant factors, but lack of ecological knowledge and a holistic approach among those performing the evaluatio...
