The Thar Desert occupies about two-third part in the State of Rajasthan. Traditionally, agriculture in this region depends on the scanty rainfall. Irrigation was introduced in ths area by commissioning Indira Gandh Nahar Pariyojona (IGNP). The total irrigation potential is estimated as 13.87 lakh hectares. Canal irrigation has brought a significant change in the cropping pattern. The traditiona...

The Great Western Development Strategy (GWDS) is a long term national campaign aimed at boosting development of the western area of China and narrowing the economic gap between the western and the eastern parts of China. The Strategic Environmental Assessment (SEA) procedure was employed to assess the environmental challenges brought about by the western development plans. These plans include f...

Abstract. Olive (Olea europaea L.) orchard brackish water irrigation with incorrect management reduces soil fertility and degrades health through salinization. This study was conducted in the Beit She'an Valley, one of main agricultural regions Israel, an olive which a combination salinization poor drainage conditions impedes plant development causes severe economic damage. By combining various...

Saltwater intrusion driven by water extraction, coastal modifications, and climate change may alter the biogeochemical cycling of freshwater coastal wetlands. Anaerobic respiration in freshwater wetlands is typically dominated by methanogenesis, leading to a high methane (CH 4 ) flux, but the availability of sulfate (SO4 2— ) in seawater may shift the dominant pathway to SO4 2— reduction, decre...

Young bell pepper (Capsicum annuum L.) plants grown in nutrient solution were gradually acclimated to 50, 100, or 150 moles per cubic meter NaCl, and photosynthetic rates of individual attached leaves were measured on several occasions during the salinization period at external CO(2) concentrations ranging from approximately 70 to 1900 micromoles per mole air. Net CO(2) assimilation (A) was plo...

This research attempts to collect and interpret the soil salinization in the upper stream of the Tarim River on the basis of the multisource and multi-type remote sensing images and basis background data in the springs of 1999, 2002 and 2004 respectively, applying the information technologies of remote sensing (RS), global positioning system (GPS), geographic information system (GIS), and massi...

The prevention of soil salinization and managing agricultural irrigation depend greatly on accurately estimating salinity. Although the long-standing laboratory method measuring salinity composition is accurate for determining parameters, its use frequently constrained by high expense difficulty long-term in situ measurement. Soil northern Nile Delta Egypt severely affects agriculture sustainab...
