Climate change is one of the greatest challenges in the 21st century and the agriculture sector is very vulnerable to this phenomenon. Since wheat is the most important cereal crop in Iran, we aim to analyze the potential impact of climatic variables (temperature and precipitation) on rainfed wheat productivity in Hamedan Province, Iran. For this purpose, generalized additive models have been used to model yields of rainfed wheat based on climatic variables during 2004–2012. Then, based on sensitivity of rainfed wheat to temperature and precipitation in this period, we predict the potential effects of climate change on rainfed wheat yield under the IPCC SRES A1FI and B1 climate change scenarios. Results suggest that yields of rainfed wheat would decrease in all Hamedan's counties primarily because of decreasing October to June precipitation and higher temperature. As a result, it is predicted that the yield of rainfed wheat in Hamedan under the A1F1 and B1 scenarios will fall by 41.3% and 20.6%, respectively, in the 2080s. In other words, according to the A1F1 scenario, in the 2080s, Hamedan Province's rainfed wheat production will decline from 1090 kg/ha to 639 kg/ha and under the B1 scenario to 865 kg/ha.
Analyzer underpins growth of container inspection company
After a career as a customs officer in the Netherlands, Wim van Tienen was well aware of the toxic gas hazards presented by some freight containers, so in 2009 he started a company, Van Tienen Milieuadvies B.V., offering gas analysis and safety advice. The company grew quickly and now employs 23 staff. Wim attributes a large part of this success to the advanced FTIR gas detection and analysis technology upon which the company’s services depend. Background It has been estimated that there are more than 17...
Study: Biological treatments in early production of tomatoes
At Vineland Research and Innovation Centre in Ontario, Plant Pathology Research Technician Travis Cranmer is working to analyze the efficacy of biopesticides against root diseases in hydroponic tomato production. The study’s findings were released at the Canadian Greenhouse Conference in Niagara Falls in October 2016. Cranmer shares some of his conclusions.
Hydrogen Sulfide Analyzers – Finding the Right Fit for Your Needs
Monitoring hydrogen sulfide (H2S) levels is critical for air quality, safety and environmental professionals across a multitude of industries. Doing so helps prevent complaints, citations, penalties, corrosion, fires, illness, and even death. A number of methods have been developed to measure trace levels of H2S The most widely used measurement methods include gold film analyzers, SO2 conversion, colorimetric gas detection tubes, electrochemical detectors, and lead acetate cassette tape gas detectors. This...
Choosing the Right H2S Analyzer for Your Specific Application
Not all H2S analyzers are created equal, and certain H2S analyzers work better on different applications than they do others. Significant amounts of time, money and headaches can be saved by learning about the different H2S analyzer principles of operation and choosing the correct analyzer for your given application. Measurement of H2S (hydrogen sulfide) is a critical task for product quality control and personnel safety applications. Higher H2S levels results in a less valuable product. It’s important...
Condition assessment program continues in North Queensland
Justification of an ongoing condition assessment program can, at times, be difficult for water utilities. However, successful inspections that deliver actionable outcomes on how to manage aging assets make this justification much easier. Certainly that was the case for Mackay Regional Council (MRC) when it engaged the services of Pure Technologies (Pure) to conduct a variety of condition assessment inspections on their critical mains in order to improve their understanding of these aging assets. For MRC, the...
