The Baltic Sea is one of the most investigated water bodies in the world. For
decades, the many highly industrialised nations around the Baltic have financed
basic and applied investigations, as well as the building and development of
research stations and vessels.
After World War II, research in the Baltic Proper was intensified and investigations
became much more international. The main goals of such investigations were
analysis of the eutrophication and pollution of the Baltic Sea, and development of
mitigating strategies (e.g. the HELCOM-Program).
Society uses water to generate and sustain economic
growth and prosperity, through activities such as farm-
ing, commercial ﬁ shing, energy production, manufactur-
ing, transport and tourism. Water is important in deciding
where we settle and how we use land. Water can also be
a source of geo-political conﬂ icts – in particular where
water shortages occur. For our own well-being, not only
clean drinking water but also clean water for hygiene and
sanitation is crucial.
This paper identifies five water environmental problems in the Delta that are the principal limiting factors of agricultural production and human health, i.e. (i) the salinity intrusion in the coastal areas, (ii) the effect of acid sulfate soils, (iii) the polluted water from human activities, (iv) the fresh water shortage in the dry season and (v) the flood in the rainy season. The discussion and conclusion present the people’s adaption strategies and water gorvernance issues in pursing sustainable management in the region.......
Late in the year 1970, a major turning point occurred in my scientific career: I joined
the staff of a federal fisheries research center at Sandy Hook, New Jersey. One of
the principal programs of that center was to examine the effects of coastal pollution
on productive systems of the oceans, especially effects on fish and shellfish resources.
About 70% of the worlds population dwells in coastal zones. With
the economic and population growth, the shortage in freshwater supply
becomes increasingly acute. With surface water more and more depleted and
polluted, coastal communities have turned to groundwater to make up for the
shortfall. For domestic supply purposes, the percentage of groundwater use
has increased to more than 40% on a worldwide basis.
Water is an important natural resource which forms the core of the ecological system. Human use of water depends on ambient water quality and human alterations of the landuse have an extensive influence on water quality. Water is typically referred to as polluted when its quality is adversely affected by contaminants and undergoes a marked shift in its capability to support the biological communities. The book is written for research scholars, hydrologists and environmentalists and especially students....
The main objective of the project is to develop and expand clam technology (production of seeds and livestock) to sustain the livelihoods of poor farmers in coastal North Central Province and develop a management strategy contributes sustainable water use clam aquaculture to improve the use of wastewater tomtrang camp. Significant progress has been made in this section. Key findings are listed below.
The main objective of the project is to develop and expand technology clam

The central provinces and develop a strategy to contribute sustainable fisheries
environmental management by using clam aquaculture to improve shrimp farm effluent
to use. In the first half of the second year, two production test clam
(producing intertidal clam, clam production in the pond is crop rotation) and
the parent test has been completed successfully....
Water conservation encompasses the policies, strategies and activities to manage fresh water as a sustainable resource to protect the water environment and to meet current and future human demand. Population, household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and agricultural irrigation.
Nitrogen contamination may come from a variety of
sources: municipal sewage, animal manure, atmospheric
deposition, biological N ﬁxation, soil organic N, and/or
nitrogen fertilizers. The consequences of contamination in
a speciﬁc water body will depend upon the amount of
contamination from all sources and characteristics of the
receiving waters. Shallow rivers, wetlands, lakes, and
reservoirs, have some capacity to remove nitrogen by
This lab uses freshwater sponges as model organisms to examine the biological effects of
water pollution. Specifically, the focus of this laboratory module is on the effects that chemicals of
environmental concern (e.g., endocrine disrupters) have on sponge growth and development.
Contamination of aquatic ecosystems is a serious issue in environmental science. Identifying which
chemicals we should be concerned with, and determining the consequences of contamination by
specific compounds, is a major area of current research.
In 1972, the Clean Water Act (CWA) delineated the basic structure for regulating discharges of
pollutants into waters and for establishing quality standards for surface waters under the authority of
EPA . Under the CWA’s National Pollutant Discharge Elimination System program, stormwater
permits were required for sediment runoff from construction sites and discharges of pollutants into
surface waters . The permitting system requires adoption of technology-based and water quality-based
effluent limits [11,12].
The question of the origin of water on Earth, or the question of why there is clearly
more water on the Earth than on the other planets of the Solar System, has not been
clarified. There are several acknowledged theories as to how the world's oceans were
formed over the past 4.6 billion years.
The litho-hydrodynamic and environmental conditions in the Vietnamese coastal estuarine basin are significantly affected by the land-ocean-atmosphere interaction processes whish tide has a determining role. Application of the coupled 1D, 2D and 3D modeling system could resolve this complicated problem but
it requires other solutions related with the boundary and coupling conditions.
Cua Viet is the Thach Han river’s mouth. It is quite big estuary that is located in the central coastal province of Quang Tri. In which, Cua Viet port plays an important role for water transport and commerce of the province. In recent years, accretion and erosion have occurred increasingly in term of scale and intensity. In addition, estuarine access channels suffer severely from sedimentation.
(Đánh giá chất lượng nước và các giải pháp tích hợp cho quản lý tài nguyên nước bền vững trên địa bàn tỉnh Sóc Trăng) This work aims to assess water resources for domestic and irrigation purposes in coastal areas of Soc Trang province- one of the most vulnerable regions in the Mekong Delta to climate change and sea level rise, especially along the coastal areas where is severely affecting by seawater intrusion.

If better management (BMP) was adopted in Vietnam there is evidence that the current trends and past environmental degradation can be stopped and even reversed, and shrimp production efficiency can be increased.
