Miracle Rice Uses Less Water to Grow, Emits Less Methane


A new type of rice being cultivated by the best canadian pharmacy to buy viagra University of wow)) viagra fast delivery Agricultural Sciences in Bangalore, India has many advantages over typical rice varieties -- it requires less water to it's great! viagra generic brand grow, it's higher in protein and usefull link viagra soft tabs it emits less methane over its life cycle.

This rice, which is not genetically modified but a hybrid crop, uses 60 percent less water than conventional rice crops.  It only needs to be watered once a week even in arid climates and can go as long as 15 days without water.

From a nutritional standpoint, the rice has 14 to 15 percent protein compared to seven to eight percent in conventional rice.  It also can be harvested more quickly with a similar yield to conventional rice, making it ideal for feeding the world's growing population.

So far, only about five percent of rice fields are using this new type of cultivation, but researchers are hopeful that as word spreads about this approach to rice, it will spread to more areas.

Climate Change Could Cause Chocolate Shortage


A new report from the International Center for Tropical Agriculture. a funded by the Bill and Melinda Gates Foundation, found that West Africa, where half of the world's cocoa supply comes from, is becoming less and less suitable for cocoa production as climate change brings higher temperatures and changing rainfall patterns.

The report says that between 2030 and 2050 land suitable for cocoa production will be slashed dramatically, with production having to www.strattonpublishing.com move to less suitable areas.  This change will make a huge impact on the worldwide industry and hurt the local farmers who rely on cocoa crops for their livelihood.

Global demand for chocolate has been quickly rising as developing nations like China import more of it.  The growing demand and drop in production will mean much higher prices for chocolate.

The study proposes finding new heat and cialis canada drought resistant crops that could thrive in West Africa, while helping to transition cocoa production to more suitable areas.

Urban Farming Concept with Rooftop Pods

UrbanAgriculture

While we are intrigued by the idea and we like some of the eye-catching images, we don't believe that current conditions make sense for tall urban buildings to be built expressly for growing food. That's not to say that we are in any way opposed to the idea of growing food in cities, closer to buy viagra 50 mg where it is going to be consumed, instead of trucking it from farms hundreds or thousands of buying cialis in the us miles away.

An alternative concept has been developed by Natalie Jeremijenko, an aerospace engineer and environmental health professor at New York University. Taking advantage of otherwise unused rooftop space, her rooftop pod designs minimize the only for you where can i purchase levitra weight added to the building roof by transferring the load to load bearing walls, thereby avoiding overloading the roof structure. The pods are also configured for hydroponic growth of plants, which eliminates the weight of soil. The lightweight pods are made with EFTE, the same lightweight, translucent material used for striking aquatics facility from the Beijing Olympics, and are aerodynamically designed in order to reduce the wind load added to the building.

Bringing more green into cities is a positive step, whether through exposed systems like green roofs and green walls, or with enclosed systems like this one. And producing food in the city is also an effective measure to decrease the transport needed to bring food to www.richcongress.com the people who will eat it. By using local production, food can be fresher, and varieties of fruits and vegetables that do not withstand the viagra online india rigors of transport can once again be made available.

Let's Make This Clear: Vertical Farms Don't Make Sense

verticalfarms

The inside of a skyscraper is, literally, the most expensive "land" in the world. So it probably isn't the best place to grow our food.

The idea of vertical farming (growing food in high-rise buildings in the middle of budget cialis cities instead of out on farms) has been gaining a lot of interest lately. Most recetly, it showed up on BoingBoing, one of our favorite blogs. We've seen a few of these proposals, and we've been following the concept for some time. It seems EcoGeeky enough, but a quick glance at the actual economics of farming shows that this isn't ever going to work.

At first, it seems to make all the sense in the world. Moving production of food into population centers to eliminate shipping. Creating highly efficient "food factories" that allow land elsewhere to be freed from cultivation. But when you look at some of the practicalities behind constructing buildings like these, vertical farms make no sense. As the Vertical farm Project itself notes: "The Vertical Farm must be efficient (cheap to construct and safe to operate)." And a vertical farm is the opposite of efficiency.

A farmer can expect his land to best prices for propecia be worth roughly $1 per square foot...if it's good, fertile land. The owner of cheap quality viagra a skyscraper, on the other hand, can expect to pay more than 200 times that per square foot of his building. And that's just the cost of construction. Factor in the costs of electricity to pump water throughout the thing and tramadol best price keep the www.aagon.de plants bathed in artificial sunlight all day, and you've got an inefficient mess.

Just looking at those numbers, you need two things to happen in order for vertical farms to make sense. You need the price of food to increase 100 fold over today's prices, and you need the productivity of vertical farms to increase 100 fold over traditional farms. Neither of those things will ever happen. And as much as I hate to burst bubbles, the main claim to the efficiency of cialis soft tabs online vertical farms (the elimination of transportation costs) is not vaild. Even if most of the calories we consume were to mail order viagra be grown inside of cities, almost all of it would be shipped out for processing (most of the food we eat isn't fresh veggies...you may have noticed.)

None of this is to say that we think farming will remain forever as it is today. EcoGeek is glad that there are many changes coming to agriculture, some of which will increase yields enough to keep prices low while feeding the 10 billion people the Earth will house by 2050. And with the right technologies, we should be able to do this without harming the Earth too much.

We're not even saying that farms will remain outside. Building multi-level (not necessarily muti-story) automated farming units on inexpensive land within 100 km of food processing plants, for example, might make a lot of sense. But if you're going to make farming more efficient, you aren't going to do it by moving it into the most expensive land in the world.

 

Science-fiction author (and former EcoGeek of the Week interviewee) Tobias Buckell also saw the article and offered his own comments on the topic, as well.

Fungus Yields Insulation and Packaging Material



The folks at Ecovative Design have spun out two interesting materials, both of which are made in the same way. According to the company’s website, the two founders “were fascinated by mushrooms growing on wood chips, and observing how the http://revistaneon.net/price-of-viagra fungal mycelium strongly bonded the wood chips together.”

In other words, they make materials by growing fungus in various types of best buy generic cialis discarded agricultural waste, such as husks, hulls, and other things that are largely made out of lignin – a complex polymer that gives fibrous strength to plants. The fungus digests the lignin, resulting in a (presumably gooey or wet) mixture which can be poured into a mold and dried out in shapes.

Ecovative currently makes two products: “Greensulate” (for insulation) and “Acorn” (for packaging). The insulation seems somewhat unimpressive. The insulating capacity of a piece of insulation is measured by its R-value. Greensulate has an R-value of 3, as opposed to materials such as polyurethane and polystyrene - which are bad for the environment, but have R-values of around 6 or 7.

And honestly, even if the R-value were higher, I think a lot of people would be skeptical about using an experimental material for insulation. Insulation is really important – it keeps you warm, keeps you cool and, most importantly, keeps your bills low. I’m not sure I’d want to http://www.enshift.com/buy-viagra-online-us mess around with an experimental new bio-based material.

What I often don’t care about, though, is packaging; especially when I receive items with way more of it than they require. I therefore think that Acorn is a great idea. It’s a great use for otherwise useless waste, and – unlike syrofoam – won’t stay in the ground for a millennium if you throw it away.
