Rising Temperature, Rising Food Prices
Agriculture as it exists today developed over 11,000 years of rather remarkable climate stability. It has evolved to maximize production within that climate system. Now, suddenly, the climate is changing. With each passing year, the agricultural system is becoming more out of sync with the climate system. In generations past, when there was an extreme weather event, such as a monsoon failure in ...

Subsurface drip irrigation; the future of Irrigation is Underground
Placing water beneath the soil surface via buried lines is slowly becoming the "preferred choice" of many vineyard irrigators. The reasons are many, including the absence of surface evaporation, as well as reduced weed growth, herbicide washout, maintenance, injury, and vandalism found with using conventional water application systems. The advantages of subsurface drip add to reduced cost for ...

Rethinking food production for a world of eight billion
The World Food Programme and the Chinese government jointlyannounced that food aid shipments to China would stop at the end of theyear. For a country where a generation ago hundreds of millions of peoplewere chronically hungry, this was a landmark achievement. Not only hasChina ended its dependence on food aid, but almost overnight it has becomethe world’s third largest food aid donor. The key ...

Two Approaches for Optimizing Water Productivity
Agricultural Research Service researchers in Bushland, Texas, are helping farmers make the most of their water supplies in a region where they depend on the Ogallala Aquifer, a massive underground reservoir under constant threat of overuse. Steve Evett, Susan O'Shaughnessy, and their colleagues at the Conservation and Production Research Laboratory are developing and testing soil-water and ...

The impact of climate change and soil salinity in irrigation water demand on the Gaza Strip
The presented work analyzes the potential impacts of the temperature, precipitation changes and water salinity on agricultural water demand. The study was carried out on five representative orchard crops (olive, palm, grapes, citrus and guava) that cover around 83% of the orchard farms in Gaza Strip. To achieve this goal, CropWat modeling software version 8.0 is used to calculate the ...

Ecohydrological modeling of irrigation scheduling of maize using time series analysis in the temperate region of Kashmir valley, India
Water, one of the most crucial inputs of irrigation, should be utilized judiciously to identify appropriate strategies for planning and management of irrigated farmland. The present study was conducted for the crop maize (Zea mays), grown mainly in the rabi-season (July–October), to evaluate the irrigation water requirements in the temperate region of Kashmir Valley, India during the ...

Sprinkler irrigation changes maize canopy microclimate and crop water status, transpiration, and temperature
During a sprinkler irrigation event some water is lost due to wind drift and evaporation (WDEL). After the irrigation event, plant-intercepted water is lost due to evaporation. The water lost causes microclimatic changes which could result in positive or negative plant physiological changes. We studied the microclimatic and physiological changes on two fields grown with maize (Zea mays L.) ...

Multisensor Capacitance Probes for Simultaneously Monitoring Rice Field Soil-Water-Crop-Ambient Conditions
Abstract: Multisensor capacitance probes (MCPs) have traditionally been used for soil moisture monitoring and irrigation scheduling. This paper presents a new application of these probes, namely the simultaneous monitoring of ponded water level, soil moisture, and temperature profile, conditions which are particularly important for rice crops in temperate growing regions and for rice grown with ...

UbiBot SP1 For Greenhouse Light Regulation
To grow plant plants in greenhouses, you need light. The amount of light a plant receives determines the length of time a plan remains active and its rate of growth. The most basic metabolic process of the plant is photosynthesis, and photosynthesis requires light energy. Three Aspects of Light Effect There are three aspects of light that should be considered when determining the effect that ...

A hotter planet means less on our plates
In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...
