Over 90% of Swedish agriculture is rainfed, and thus future climate change can pose a risk to agricultural production in coming decades. An overall increase annual precipitation predicted for northern Europe, but Sweden could still face an increasing need irrigation, as shown by the drought summer 2018. Adaptation include irrigated should be considered. To evaluate theoretical calculations were...

Improving the adaptive capacity of small-scale irrigation systems to the impacts of climate change is crucial for food security in Asia. This study analyzes the capacity of small-scale irrigation systems dependent on the Asian monsoon to adapt to variability in river discharge caused by climate change. Our study is motivated by the Pumpa irrigation system, a small-scale irrigation system locate...

A 31 year record of ∼44,000 nitrate analyses in ∼11,500 irrigation wells was utilized to depict the decadal expansion of groundwater nitrate contamination (N ≥ 10 mg/L) in the irrigated corn-growing areas of eastern and central Nebraska and analyze long-term nitrate concentration trends in 17 management areas (MAs) subject to N fertilizer and budgeting requirements. The 1.3 M contaminated hecta...

The conservation of aquatic plants in river ecosystems should consider the wash-out (away) problem resulting from severe rainfall. The aquatic plant Schoenoplectus gemmifer is an endangered species endemic to Japan. Our previous study reported that the population size of S. gemmifer in Hamamatsu city, Japan, had decreased by one-tenth because many individuals had been washed out by a series of ...

Technological innovations will leads to meet the present and future challenges of agriculture sector. Water is one important natural resource, since time immemorial, also acted as catalyst during Green Revolution helped India achieve self-sufficient status in food grain production. Fresh water only 2.6% total resources world has be utilized efficiently. Inspite coverage under irrigation phenome...

Among melons, cantaloupes are most frequently implicated in outbreaks and surveillance-based recalls due to Salmonella enterica. There is limited but compelling evidence that associates irrigation water quality as a significant risk of preharvest contamination of melons. However, the potential for root uptake from water and soil and subsequent systemic transport of Salmonella into melon fruit i...

an experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and chickpea cultivars on chickpea production in the khorramabad lorestan. the experiment was split–plot in a randomized complete block design with 3 replications. supplementary irrigation at 8 levels (1-rainfed without irrigation, 2-irrigation after sowing, 3-irrigation at flowering, 4-irrigation ...

climatic parameters in time and space scales of change are for many reasons of changes and how they should be based on observations using a statistical method to be determined. analysis of the most widely used statistical methods that assess potential climate change on hydrological time series, such series of precipitation, temperature and flow rate used. this study of 11 synoptic,rain gage and...

Water resources and land use are closely linked with each other and with regional climate, assembling a very complex system. The understanding of the interconnecting relations involved in this system is an essential step for elaborating public policies that can effectively lead to the sustainable use of water resources. In this study, an integrated modelling framework was assembled in order to ...
