Consultant(s) to assess water quality baseline and the impacts of aquaculture farming on wetlandsIn Vietnam, wetlands directly provide a source of livelihood for millions, and provide environmental services from flood control to water purification to biodiversity conservation that indirectly support the broader economy. The wetlands of the Mekong Delta were once extensive and varied. Today, much of the Delta has lost its natural habitat, although remnants of the once extensive peat swamp forests, freshwater forests and flooded grasslands are represented in these wetlands. As the last representation of these significant habitats, important for distinctive plant communities, threatened bird communities and other significant animals, conservation efforts are now highly critical and is an urgent priority.
Tram Chim National Park (TCNP) represents the last remaining one percent of the Plain of Reeds in existence. It is the 2000th Ramsar site designated globally and also supports over 200 species of vertebrates, 40 species of fish and 147 species of waterfowl. Many globally rare bird species occur in TCNP, such as Sarus crane, pelicans and lesser adjutants. Fauna and flora of the park are characteristic of the Plain of Reeds and are nationally representative of inland wetland, Mekong River riparian, acid sulphate soil, and seasonal flooding areas.
Yet, the health of wetlands ecosystems is under threat. In the Mekong Delta, the most immediate threats stem from efforts to intensify rice production and expand aquaculture, driven by new market opportunities, by the local demands of a growing population, and, in many cases, by poverty and lack of alternative livelihoods. Especially, since expansion of aquaculture in the Mekong Delta, major environmental impacts of aquaculture have been associated mainly with high-input, high-output intensive systems, the effects of which included discharge of suspended solids, and nutrient and organic enrichment of recipient waters resulting in build-up of anoxic sediments, changes in benthic communities and the eutrophication of river catchments. Besides, wastewater is, at times, directly released untreated into the environment. Such pollution could affect the long-term health of people and nature in the area by causing, among other issues, water-borne diseases and pollutants to spread.
For better management of TCNP and improve living environment of people in the areas, it is vital to carry out water quality assessment and value the impacts of aquaculture farming on wetlands.
It is, therefore WWF-Viet Nam is seeking a consultant(s) to carry out water quality baseline in TCNP area and to study the impacts of aquaculture farming on wetlands, then propose solutions for better management/conservation of water resource and wetlands in the areas.
The objectives of the consultancy are:
- To carry out water quality baseline for TCNP areas.
- To study the impacts of aquaculture farming on wetlands (including spreading of water pollutants from aquaculture to wetland areas).
- To propose solutions for better management/conservation of water resources and wetland in the area.
2. Scope of work/ Major responsibility
Depending on the consultants to achieve the above mentioned objectives, the work may include:
2.1. Water quality baseline assessment
- Mapping appropriate survey/sampling sites.
- Sampling and analyzing for the following assessments:
- Organic pollution
- Nutrient pollution
- Acid water spreading
- Other pollution
- Surveying the current situation of socio-economic and enviornment of the aeras.
- Report writing for rainy season and dry season.
- Mapping wetlands/protected areas in the Mekong Delta, especially in the Plain of Reeds.
- General wetland characteristics (biodiversity, landscapes, conservations, drivers of changes, etc.).
- Mapping aquaculture farming in the Mekong Delta, especially in the Plain of Reeds and TCNP areas.
- Mapping appropriate survey/sampling sites.
- Sampling and analyzing.
- Desk study: data analyzing, assessing, simulating, report writing, etc.
