China is facing intense coastal eutrophication. Large-scale seaweed aquaculture in China is popular, now accounting for over 2/3's of global production. Here, we estimate the nutrient removal capability of large-scale Chinese seaweed farms to determine its significance in mitigating eutrophication. We combined estimates of yield and nutrient concentration of Chinese seaweed aquaculture to quant...

[1] Groundwater recharge is critical in semiarid regions where aquifers are currently being mined for intensive irrigation. Land use management related to agriculture can be used to control partitioning of water near the land surface and to potentially manage water resources. The purpose of this study was to quantify impacts of deep plowing in rainfed (nonirrigated) agriculture in a semiarid re...

Background: Due to the increasing pollution of water resources, this study was carried out for evaluation of water quality pollution indices for monitoring of heavy metals (As, Zn, Pb and Cu) contamination in Ghahavand Plain, Hamadan Province, Western Iran during spring and summer 2012. Methods: Totally, 20 ground water wells were chosen randomly. The samples were filtered (0.45 μm) and m...

achieving the self-sufficiency in producing agricultural crops and decreasing the pressure on the available water resources need determining the fertile places for cultivation based on the suitable evaluating indices. in this research, the prioritization of different township in sistan and blouchestan province for onion cultivation, as one of the most important production in the province, was c...

development projects in natural water resources like rivers and lakes, specially transferring water to use in agriculture, domestic and industrial sector without considering environmental values, causes irrecoverable and irreversible damage to ecosystem and future options. if we consider the future generation and species rights, those damages and costs can be very much than we take in. the abov...

The designs of Water distribution systems are based on certain objectives such as equity, adequacy to access its efficacy. The design of canal systems for distributing the water is based on the size of command areas. Duration of operation. It is a fact that Odisha is a predominantly agrarian state as more than 2/3rd of the state population depends on agriculture. Irrigation is the paramount imp...
