Extensive arsenic contamination of groundwater, rivers, and agricultural farms has led to widespread poisoning consequent problems associated with health economy. In recent years, many studies have been performed understand bacterial detoxification metabolism which paved the way for bioremediation applications. This study attempted isolate characterize arsenic-resistant bacteria from drying Urm...
The spatial distribution of surface sediment diatoms in Chaohu Lake (southeast China), and their relationships with environmental and spatial variables were analyzed in this study. The diatom assemblages were dominated by planktonic species. Three dominant species Cyclostephanos dubius, Aulacoseira granulata and Aulacoseira alpigena are unevenly distributed across the lake. The distribution of ...
Abstract Water productivity (WP) is one of the most important critical indicators in essential planning water consumption agricultural sector. For this purpose, WP and economic (WPe) were estimated using agronomic technologies. The impact technologies on WPe was carried out two parts field monitoring modeling novel intelligent approaches. Extreme learning machine (ELM), adaptive neuro-fuzzy inf...
Potential of the hazelnut tree search–ELM hybrid approach in estimating yield and water productivity
Abstract Wheat plays a vital role in the food security of society, and early estimation its yield will be great help to macro-decisions. For this purpose, wheat water productivity (WP) by considering soil data, irrigation, fertilizer, climate, crop characteristics using novel hybrid approach called hazelnut tree search algorithm (HTS) extreme machine learning method (ELM) was examined under dri...
Many saline lakes throughout the world are shrinking due to overexploitation of water in their drainage basins. Among them two world’s largest lakes, U.S.A.’s Great Salt Lake, and Iran’s Lake Urmia. Here we provide a comparative analysis desiccation these that provides insights on management decisions may help save relevant lake worldwide. Urmia were once remarkably similar size, depth, salinit...
Human settlements as local -spatial systems are subject to continuous dynamism and transformation. In the meantime, rural settlements including; in Iran, as the most important establishment of population and activity, are exposed to the deepest environmental, ecological, social, economic and cultural changes. It is evident that in these developments, a variety of different and different forms o...
Declining water level of Lake Urmia is one of the environmental crises that has affected the adaptation capacity of the villagers around it. As it has incurred great costs in economic, social and environmental dimensions for the rural residents around it. Therefore, the purpose of this study is to study the factors and forces affecting the adaptation capacity of rural settlements in the face of...
Urmia Lake is the largest lake in the Iranian plateau and the second largest Salt Lake in the world. This study was conducted to identify hypersaline bacteria in the lake through the screening with molecular markers. For the molecular study of the bacterial microbiome of the lake, samples were collected from water, sludge and soil of the different parts of the lake during different seasons of 2...
introduction average per-capita renewable water of iran is decreasing strongly. in near future water wars in the middle east are predictable. exploitation of land resource has the most significant impact on wetlands. wetlands degradation is the serious warning to unsustainable development. despite that the lake urmia is recorded in conservation lists as iranian national parks, ramsar sites and ...
