Saline water

Saline intrusion is a big challenge for the Mekong Delta region, a negative factor that greatly affects water and food security. This paper presents a study to assess the trend of saline intrusion change in the 5 coastal sub–regions between the Tien and Hau rivers in the period 1997 to 2022.

Salinity is one of the most devastating abiotic stresses limiting crop production. Considering this issue, a pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the boro season (2017-2018) using two rice (Oryza sativa L.) varieties, namely BRRI dhan28 (salt sensitive) and BRRI dhan47 (salt tolerant), to assess the effects of varied salinity levels on the growth and the performance of the rice varieties under salt stress conditions.

In Vietnam, there have been some studies on desalination but mostly on low and stable salinity and small-scale system. In fact, the salinity varies quite substantialy within seasons. Thus, the main objective of this study is therefore to evaluate the brackish water treatment capacity of different nanofiltration (NF) processes for domestic and drinking water supply for residential areas in Thu Bon river basin.

With the impact of global climate change, saline intrusion into surface water in coastal areas has become a major issue. The water treatment using surface water in these areas has to deal with double issues including organic matters and salinity. This paper evaluated the trihalomethanes formation during the treatment of surface water at pilot scale using different disinfection dose and at different salinity levels.

Monitoring and evaluation of saline water intrusion is an important task, especially for agricultural production in Ben Tre province. The paper introduces a new solution in the application of Landsat 8 satellite imagery and field survey data to determine the soil electrical conductivity (EC) for soil salinity assessment through the distribution of EC indice value.

Use of poor quality water for agriculture production requires appropriate management strategies such as leaching of excessive salts, selection of salt tolerant crops, frequent application of water etc. Thus a field experiment was conducted at CCS Haryana Agricultural University, Hisar to study the salt dynamics in soil under drip irrigation system on cabbage crop and to investigate the effect of frequency and salinity levels of irrigation water on cabbage.

Hypovolemia: Treatment The therapeutic goals are to restore normovolemia with fluid similar in composition to that lost and to replace ongoing losses. Symptoms and signs, including weight loss, can help estimate the degree of volume contraction and should also be monitored to assess response to treatment. Mild volume contraction can usually be corrected via the oral route. More severe hypovolemia requires intravenous therapy. Isotonic or normal saline (0.

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.......
