However, urbanisation, extensive irrigation and variations in rainfall patterns due to global climate change have led to serious water scarcity in many areas of the world.
and the human contribution can arise from activities such as mining, large construction works or water extraction for irrigation.

But now research is offering an intelligent irrigation system to monitor how much water is being held in the soil, automatically spraying when needed.
The waste is mainly down to inefficient irrigation systems. But better managed, it could mean more water resources for other basics like drinking, hygiene and cooking.
low power consumption wireless sensor network, sending the data to an intelligent web service software application for analysis. Once the numbers are crunched-taking due account for weather and other local parameters-it automatically activates the selected irrigation nodes in the areas

through insecticide-treated bednets and indoor sprays, is one of the best ways to win the battle.
But mosquitoes are becoming resistant to insecticides potentially reversing the gains made so far. In response, the EU-funded MCD project has developed three new weapons against them a special coating that transfers insecticides effectively to mosquitoes landing on it,
insecticide-laced ave tubesto direct them to the coating, and a bednet patch. The project began work in December 2012
and is now negotiating with a manufacturer in Tanzania to mass produce these low-cost devices
This has been repurposed for mosquito control using the netting coated with insecticide at one end of tubes that are placed in the walls of the households.

#Iron-rich biochar filters arsenic from water Biochar may be a fast inexpensive and easy way to remove arsenicâ one of the world s most common pollutantsâ from water.
Because biochar can be produced from various waste biomass including agricultural residues this new technology provides an alternative
The resulting biochar which has the consistency of ground coffee was treated then with a saltwater bath to impregnate it with iron.
Plain biochar does not have the same effect Gao says. Current methods to remove arsenic include precipitation adding lime
Water treatment plants could use large biochar filters to extract the arsenic. Homeowners could use a small filter attached to their tap.
#Proteins could detox pesticides and sarin gas Scientists are developing a way to prevent brain damage among people exposed to poisonous chemicals found in pesticides and chemical weapons.
The work, published in the journal Chembiochem, centers on proteins called phosphotriesterases, which degrade chemicals in a class known as organophosphates.
Organophosphates are found in everything from industrial pesticides to the sarin gas used in chemical warfare. They permanently bond to neurotransmitters in the brain,
whether through exposure to pesticide or an intentional chemical warfare attack, explains Jin Kim Montclare, associate professor of chemical and biological engineering at the New york University School of engineering. ee known that phosphotriesterases had the power to detoxify these nerve agents,

#Biochar changes how water flows through soil Rice university rightoriginal Studyposted by Jade Boyd-Rice on September 25 2014new research could help settle the debate about one of biochar s biggest benefits#its seemingly contradictory ability
or biochar to soil to both boost crop yields and counter global climate change the study offers the first detailed explanation for this mystery. nderstanding the controls on water movement through biochar-amended soils is critical
to explaining other frequently reported benefits of biochar such as nutrient retention carbon sequestration and reduced greenhouse gas emissionssays lead author Rebecca Barnes an assistant professor of environmental science at Colorado College who began the research as a postdoctoral research associate at Rice university.
Biochar can be produced from waste wood manure or leaves and its popularity among DIY types
and gardening buffs took off after archaeological studies found that biochar added to soils in the Amazon more than 1000 years ago was still improving the water-and nutrient-holding abilities of those poor soils today.
Studies over the past decade have found that biochar soil amendments can either increase or decrease the amount of water that soil holds
In the new study biogeochemists at Rice conducted side-by-side tests of the water-holding ability of three soil types#sand clay and topsoil#both with and without added biochar.
The biochar used in the experiments derived from Texas mesquite wood was prepared to exacting standards in the lab of Rice geochemist Caroline Masiello a study coauthor to ensure comparable results across soil types. ot all biochar
is created equal and one of the important lessons of recent studies is that the hydrological properties of biochar can vary widely depending on the temperature
and time in the reactormasiello says. t s important to use the right recipe for the biochar that you want to make
When biochar is added to clay it makes the soil less dense and it increases hydraulic conductivity
which makes intuitive sense. dding biochar to sand also makes it less dense so one would expect that soil to drain more quickly as well;
but in fact researchers have found that biochar-amended sand holds water longer. tudy coauthor Brandon Dugan assistant professor of Earth science at Rice says e hypothesize that this is likely due to the presence of two flow paths
for water through soil-biochar mixtures. One pathway is between the soil and biochar grains
and a second pathway is water moving through the biochar itself. arnes says the highly porous structure of biochar makes each of these pathways more tortuous than the pathway that water would take through sand alone.
Moreover the surface chemistry of biochar#both on external surfaces and inside pores#is likely to promote absorption
and further slow the movement of water. y adding our results to the growing body of literature we show that
when biochar is added to sand or other coarse-grained soils there is a simultaneous decrease in bulk density
It also extracts nutrients that can be reused as fertilizer. Currently the system produces about 50 gallons of water from 100 gallons of manure.
says Steve Safferman, an associate professor of biosystems and agricultural engineering at Michigan State university, who is involved with the project. bout 90 percent of the manure is water
and can be reused as fertilizer . or example, wee able to capture a large percentage of the ammonia that would otherwise be lost in the atmosphere,
For example sophisticated vintners use precise irrigation to put regulated water stress on grapevines to create just the right grape composition for a premium cabernet or a chardonnay wine.
and coastal waters where fertilizer runoff and other organic waste can deplete oxygen levels and suffocate marine life.
#Use microbes, not pesticides, to boost crop yields Iowa State university Original Studyposted by Fred Love-Iowa State on September 9 2013.
The recommendations published in the Academy s Colloquium Reports set a goal of increasing yields by 20 percent over the next 20 years by enhancing the use of microbes while reducing the use of pesticides and fertilizers by 20 percent.
and lessen the need for costly fertilizers and pesticides says team member Gwyn Beattie a professor of plant pathology and bacteriology at Iowa State university.
Reaching those goals would drastically cut input costs for farmers and produce a range of environmental benefits.
and you get a prototype device known as the Farm Level Optimal Water management Assistant for Irrigation under Deficit or FLOW-AID.
so they don run their irrigation systems unnecessarily. FLOW-AID was developed by a group of 11 European companies and research institutes
when levels drop to the point that irrigation is required, at which point they can start their irrigation system remotely via their phone.
As soon as they see that sufficient moisture levels have been restored they can use their phone to turn the irrigation back off.
The system also incorporates software that takes location-specific factors such as plant properties, soil characteristics and water rationing limits into account.
it can additionally advise users on how often fertilizer should be applied this stops farmers from wasting money by over-fertilizing,
and minimizes the amount of excess fertilizer entering the environment. It estimated that the system could lead to a reduction in fertilizer use of up to 30 percent

Through this project Fan developed a faster way of treating the biochar particles using a new technology called plasma activation.
The plasma treatment activates the biochar in five minutes and at room temperature Fan explained. Conventional chemical activation takes several hours to complete
The technique that treats biochar electrodes for supercapacitors can also be used in making displays explained Fan who was a research scientist at Wintek more than 10 years ago.
As a result the mosquitoes were more prone to insecticides as they no longer had a sufficient amount of chitin for a normal functioning protective shell.
If the production of chitin can be reduced further the insects can be killed without using any toxic insecticides.

#Biochar from manure waste enhances soils Researchers at Universidad Politécnica de Madrid have obtained biochar using manure waste,
Biochar, a material obtained after thermal treatment of this waste through pyrolysis, is an organic fertilizer that applied in soils
This waste contains fertilizers, and its production has increased over the last years because of intensive farming and has been used traditionally in soils as an organic amendment.
However, its high-volume production and the generation of environmental problems (eutrophication and pollution of groundwater due to its high concentration of nutrients
It is highlighted the thermal treatment through pyrolysis for large scale production of biochar or biocarbon that can be defined as a carbonaceous material obtained through thermal treatment of biomass at low temperatures and under inert atmosphere.

The remaining solid is applied as a fertilizer on the fields in the vicinity. It is our vision for the future that such plants in the urban area are served by tank vehicles
There the organic wastes are converted into biogas and fertilizer within a period of one month. Via a pipeline system the gas is passed directly on to the gas stoves of the neighboring houses.
and used as a fertilizer. At first we had to work hard to convince the population Fuchs says.
and to lower environmental impact since this fertilizing system represents an alternative to the mineral fertilizers used so far.
This method can help increase crop yields its application is similar to use a fertilizer but having better results
and without the contamination issues than can produce the mineral fertilizers. Thus its application in agriculture horticulture forestry plants ornamental plants or any other plant with commercial interest would represent a significant environmental and economic saving.
and create biochar a highly porous charcoal said project principal investigator Karl Linden professor of environmental engineering.
The biochar has a one-two punch in that it can be used to both increase crop yields
Biochar is a valuable material said Linden. It has good water holding capacity and it can be used in agricultural areas to hold in nutrients
A soil mixture containing 10 percent biochar can hold up to 50 percent more water and increase the availability of plant nutrients he said.
Additionally the biochar can be burned as charcoal and provides energy comparable to that of commercial charcoal.
Sensor-based irrigation systems show potential to increase greenhouse profitability Wireless sensor-based irrigation systems can offer significant benefits to greenhouse operators.
Advances in sensor technology and increased understanding of plant physiology have made it possible for greenhouse growers to use water content sensors to accurately determine irrigation timing and application rates in soilless substrates.
and can save irrigation water labor energy and fertilizer. The authors of a report published in Horttechnology said that the use of sensor-based irrigation technology can also accelerate container and greenhouse plant production time.
Erik Lichtenberg John Majsztrik and Monica Saavoss reported on a study they designed to determine an optimal formula for ascertaining the true profitability of precision irrigation systems.
Sensor-based irrigation systems substitute capital for water and associated inputs such as energy labor and fertilizer the authors explained.
When benefits and costs accrue at different points in time calculating profit --or indeed comparing them in any way--requires putting benefits and costs on a common time footing.
The scientists found that controlling irrigation using data from moisture sensors led to substantial reductions in both production time and crop losses.
even if efficiency gains are not as high as those in the study controlling irrigation using wireless sensor systems is likely to increase profitability substantially.
