With the consequence of climate change, it gradually extends towards inland water and soil. This scenario of gradual salinity intrusion into the coastal areas of Bangladesh is very threatening to the primary production system, coastal biodiversity and human health, said researchers. The total amount of salinity affected land in Bangladesh …
The European Commission’s Joint Research Centre and FAO's Global Soil Partnership collaborated with experts from across Asia and other regions to produce the first-ever Soil Atlas of Asia. The aim of the Atlas is to raise awareness about the significance of soil to life in Asia among a wide range …
The Food and Agriculture Organization (FAO) launched the Global Map of Salt-Affected Soils, a key tool for halting salinization and boosting productivity. The map estimates that there are more than 833 million hectares of salt-affected soils around the globe (8.7% of the planet). Most of them can be found in …
The rice model ORYZA v3 has been recently improved to account for salt stress effect on rice crop growth and yield. This paper details subsequent studies using the improved model to explore opportunities for improving salinity tolerance in rice. The objective was to identify combinations of plant traits influencing rice …
This report discusses in detail the occurrence of coastal land salinity, its impact on crop yield and environment, and various management techniques to mitigate the adverse impacts, including those of coastal flooding arising from storm surges and anticipated climate change. The state-wise physiography and drainage, hydrogeology, and, causes and extend …
Plants with rising atmospheric carbon dioxide (CO2) level in the environment may change their nutrient demands to sustain growth. The mechanisms concerning iron dynamics in plants under the interactive effect of salinity and elevated CO2 are poorly understood. This study examines the effects of long-term as well as short-term growth …
This study was conducted to investigate the characteristics of inflow and outflow wastewater of the Bandargaz wastewater treatment plant on the basis of the data collection of operation period and the samples taken during the study. Also the effects of mid-term use of the wastewater for irrigation (from 2005 to …
After the 2011 Tohoku earthquake, thirteen thousand hectares of farmlands were damaged by massive Tsunami near coastal sites in Miyagi, Japan. Some eighty percent of the damaged farmlands have been recovered in 2014, but subsidence and high salinity groundwater make it difficult to completely remove salinity from the soil. To …
Munrothuruthu (‘Munroe Island’) is a place renowned for continuous settlement, in the Kollam district of Kerala. The Indian Ocean earthquake and Tsunami of 2004 triggered this major problem. The island is located at confluence of the Ashtamudi Lake and the Kallada River. Low lying regions of the island are facing …
Subsurface drainage has been used for more than a century to keep water table at a desired level of salinity and waterlogging control. This paper has been focused on the impact assessment of pilot studies in India and some other countries from 1969 to 2014 . This review article may …
Judgement of the National Green Tribunal (Southern Zone) in the matter of V.Periyakudi Muniyasamy Vs.The District Collector, Ramanathapuram dated 24/08/2015 regarding M/s.Chemfab Alkalis Limited from establishing salt pan in the lands purchased by the industry contending inter alia that the area concerned is an agricultural land and by the activity …
Alkali lands in India occupy about 3.8 m ha. Due to poor physical properties, excessive exchangeable sodium and high pH, most of these lands support a poor vegetative cover. These lands are reclaimed using costly amendments such as gypsum, phospho-gypsum or press mud. In recent times many of the medicinal …
Rapid and reliable assessment of soil characteristics is an important step in agricultural and natural resource management. Over the last few decades, diffuse reflectance spectroscopy (DRS) has emerged as a new tool to obtain both qualitative and quantitative information on soil in a non-invasive manner. The DRS approach is attractive …
Vietnamese communities in the Mekong Delta are faced with the substantial impacts of rising sea levels and salinity intrusion. The construction of embankments and dykes has historically been the principal strategy of the Vietnamese government to mitigate the effects of salinity intrusion on agricultural production. A predicted sea-level rise of …
Rice is sensitive to salt stress, especially at the seedling stage, with rice varieties differing remarkably in salt tolerance (ST). To understand the physiological mechanisms of ST, we investigated salt stress responses at the metabolite level. Original Source
Hexaploid bread wheat is generally more salt tolerant than its tetraploid progenitor. However, the physiological bases and the relative contributions of immediate effects of polyploidization and subsequently acquired adaptive changes in the salt tolerance of hexaploid wheat remained elusive. This study compared a large suite of morphophysiological traits in synthetic …
The expansion of coal mining in the Hunter Valley and the increase in the number, area and depth of surface mines has changed the landscape as well as the economic and social character of the region. Given the extent of new mining still proposed for the Valley, the impact of …
Judgement of the National Green Tribunal in the matter Gau Raxa Hitraxak Manch and Gauchar Paryavaran Pouchav Trust Rajula Vs Union of India & Others dated 22/08/2013 regarding granting Environmental Clearance (EC) to expansion of a Port - M/s Gujarat Pipavav Port Ltd. (R-3).
The amount of land needed to grow crops worldwide is at a peak and an area more than twice the size of France can return to nature by 2060 due to rising yields and slower population growth, a group of experts said on Monday. The report, conflicting with U.N. studies …
The rural populations of southern Bangladesh are some of the most vulnerable communities in the world to the future impacts of climate change. They are particularly at risk from floods, waterlogged soils, and increasing salinity of both land and water. The objective of this project was to analyze the vulnerability …
