Farmland Ownership Trends Shifting
Jeff Caldwell 08/06/2013 @ 9:15amMultimedia Editor for Agriculture.com and Successful Farming magazine. As farmland values have climbed over the last few years, it’s caused a slowing in a couple of key trends in who owns that land, shifts that could ultimately affect land accessibility for young and beginning farmers, according to one Iowa land values expert. Every five years, Iowa State University Extension farm management specialist Mike Duffy conducts a survey of farmland owners in his state. The survey has been conducted since the early 1980s, a time period that’s seen some major ups and downs in the land market. “The latest Iowa farmland ownership survey is compared to previous surveys dating back to 1982, during the time when farmland values first started collapsing after the boom of the 1970s,” Duffy says, adding that the full results of the survey will be released later this fall. “Looking at the various surveys over the past 30 years shows some of the changes in farming technology, demographics, and other patterns. The 2012 survey also shows the impact of the current land boom on these trends.” The sharp climb in land values since the last land ownership survey conducted in 2007 — a time when values in Iowa had more than doubled — has caused a couple of shifts in ownership that could carry implications for young and beginning farmers in the coming years, provided values are sustained. First, who’s owning the land? Last year, almost one third of Iowa farmland was in the hands of someone over the age of 75. That number has been ticking up since 1982, but just in the last five years since the sharp value climb, Duffy says there’s been a noticeable change. “The percent of land owned by people in this age category had been steadily increasing since 1982, when 12% of the land was owned by someone over 75 years old. The trend toward increasing age does appear to have been slowed by the boom,” Duffy says. “There are younger owners, although they represent a small percentage of the acres. Over half, 56%, of the farmland in Iowa is owned by someone over the age of 65.” Absentee land ownership has also declined in the last few years since the runup in land values. In 2012, 21% of the farmland in Iowa was owned by an absentee owner. That’s the same as in 2007, but up 15% from 1982. Duffy says the flattening of this number could also foreshadow a major trend shift. “Another trend that seems to have slowed is the percent of land owned by people who don’t live in Iowa full-time,” he says. “It appears that the higher land values had an impact on the ownership by non-Iowans.” These trends are important for all parties involved in farmland ownership and management, but mostly for those on the opposite ends of the age spectrum, Duffy says. This makes it important for those parties to watch them closely and take them into account in land purchase and lease agreements down the road. “Ownership of Iowa’s farmland and access to the use of the land is critical for the future of the State. The impact of the ownership on both beginning farmers and the retiring farmers will be crucial,” Duffy says. “The current situation with respect to farmland ownership in Iowa is a good topic for discussion among landlords, family or heirs, and agribusiness professionals.” Continue reading
Chinese Fragrance More Precious Than Gold
By Wang Jie ( Shanghai Daily ) 08:12, August 19, 2013 Many rich Chinese are buying luxury brands of famous designer perfumes, but the ultimate luxury fragrance — one far costly than gold — is agarwood or chen xiang (沉香), an ancient Oriental fragrance. Increasingly Chinese are rediscovering their appreciation for agarwood, which played a role as incense and oil in religious rituals throughout Asia and the Middle East. The deeply aromatic fragrance is considered an aid to meditation and was very popular in ancient China. Pieces of natural wood and fragrant carvings are sought by collectors. Incense and essential oil are precious. Whenever it is burned, heated or simply placed at room temperature, it gives off a pleasant aroma — from subtle to intense. What could be more luxurious than simply burning a piece of high-quality chen xiang that costs 10,000 yuan (US$1,629) per gram of highest quality and savoring the fragrance. And then it’s gone, up in smoke. But worth it, many people say. Arguably the most costly fragrance in the world is complex, layered and difficult to describe. It is sweet, rich and deep but balanced. It’s also called earthy, smoky and sweet — deeply pleasing. For most people, chen xiang (literally “wood with mellow fragrance”) is just a piece of rotten wood. It literally is rotten. Agarwood is a dark resinous heartwood that forms in aquilaria and gyrinops trees when they become infected with a particular fungus. Before infection, the heartwood is relative pale in color, but the tree produces a dark aromatic resin in response to the attack. It is this resinous wood that is valued in many cultures. The trees are large evergreens native to Southeast Asia, but most have been cut down and now trees are commercially raised and infected with fungus in a long process. The best and most expensive chen xiang is natural and old, and some areas produce better wood than others. Although commercial agarwood has an alluring fragrance, there’s nothing like the real thing. The cost is so high because trees in nature are scarce, and the commercial farming and processing is costly. Throughout the region, locals hunt for old wood and may happen upon buried pieces that they treat like gold. Trees grow in Vietnam, Thailand, Cambodia, Malaysia, Indonesia and India. Only very small amount is produced. For chen xiang collector Wang Yinan, this is the ultimate luxury, without parallel. “The reason is clear. If you buy a house, antique or jewelry, they remain as concrete items,” he says. “But chen xiang is different. It is burned for its fragrance, the fleeting moment of enjoyment. Nothing is left, but the fragrance, the temporary fragrance. Isn’t this the most luxurious thing on the world?” Wang, a famous TV host, is director of the National Chen Xiang Research Association. In ancient times, chen xiang could only be appreciated by imperial families and high-ranking nobles. It has been used in traditional Chinese medicine as a tonic, diuretic, stimulant and aphrodisiac. It was used to treat heart pain, stomach pain, fatigue, stress and anxiety. Today the price of a piece of high-quality chen xiang can reach several million yuan. At 10,000 yuan per gram, it is 35 times the price of gold which now costs 260 yuan per gram. Some is carved into artwork. As such, it’s coveted. “I always say that if you want to start collecting something, the best way is to study and learn,” Wang says. “Today the antiques field is chaotic, filled with traps and fakes and chen xiang is no exception — even worse. I would say that 90 percent of the chen xiang in the market is faked or artificially/commercially produced.” An educated nose is the best guide to authenticity, Wang says. “Because there is no physical way to judge the authenticity of real chen xiang, the only reliable tool is your nose,” he says. “I’m not opposed to commercially produced chen xiang, but the fragrance is a thousand miles away from original one, which could only be distinguished by the nose.” Wang once visited Vietnam to see how chen xiang is discovered. “It was a magical journey. Locals searched along the river and suddenly they spotted something in the mid. After washing and cleaning, it turned out to be chen xiang, an ordinary-looking piece of wood or enormous value,” he recalls. “I am enamored of chen xiang not only because of its profound fragrance but also because the fragrance envelops everyone, rich and poor, and it lingers. But when it’s burned, it’s gone, it’s a memory,” Wang says. Continue reading
The Key To Making More Efficient Biofuels Is Taking the Wood Out of Wood
By Michael Byrne Here’s the problem with using wood as a biofuel: it’s wood . That’s it, basically. The thing we associate with wood being wood, rigidity, is what makes trees poor materials for use in ethanol production. Rigidity comes from lignin, an organic polymer that fills in the empty spaces within the cell walls of plants; its function is generally mechanical—providing structural strength for the cell and aiding in the flow of water through the plant. Lignin also burns great, but that’s a different kind of fuel. In biofuel applications, we want to get past the lignin to cellulose, which is converted to alcohol-based fuel that can be used to power our cars and trucks. Split wood isn’t the best choice for internal combustion, so the lignin just gets in the way of the part that is the best choice—sugar in the form of cellulose. Let’s stop for a moment. What exactly is biofuel? It’s diesel basically, albeit not derived from the fossil fuels we’re about to run out of and that we extract from the planet at considerable cost socially, environmentally, and economically. Biofuel isn’t “clean” fuel; it’s still a thing resulting in greenhouse gas emissions, though less per unit of energy derived than dinosaur stuff. So as far as being “better” it’s probably not much more than halfway there. But it’s here now in a world with a heavy dependency on diesel-powered trucks for moving its goods around. In many places, particularly Europe, there’s already an infrastructure for it. In several U.S. states, its use is already mandated and the highly ungreen U.S. Energy Policy Act of 2005 mandates a significant increase in biofuel use in the coming years. The point of this aside is less to argue that biofuel is good or bad than to say that “it’s here.” And biofuel being here, even against the will of those of us that might know better, means that it’s in our interest to have better and more efficient biofuel. This means making cellulose more efficient to access by eliminating the wood in wood, more or less—eliminating the lignin barrier. The solution, unsurprisingly, is GM biofuels. Let’s make trees with only the good stuff, as far as biofuels are concerned. Floppy plants. It’s a difficult task, however—the process that plants use to make lignin isn’t as obvious as in most other organic molecules. Different plants do it differently, even if it’s the same stuff fulfilling the same functions. According to a new report in Science , Wout Boerjan, a molecular geneticist at Ghent University, tracked down the correct common gene central to synthesizing lignin by way of an enzyme called caffeoyl shikimate esterase. Once identified, Boerjan experimented with silencing this central gene, with the result being plants containing a third less lignin and able to produce up to four times the amount of cellulose. They weren’t even really floppy either. The main catch is that with less of this crucial building material, the plants lost some of their ability to transport food or water. As a result, they were a bit stumpy. It’s thought this could be worked around with more engineering; maybe we could just reduce lignin in cells where it isn’t needed as much. If this is registering as kind of “whatever,” consider the United States’ ethanol problem . The U.S. grows a ton of corn, but much of it is earmarked for biofuel production. This keeps corn prices high across the globe, which keeps civilization primed for violence and unrest. If we’re able to grow biofuel crops with four times the efficiency, that’s a whole lot less farmland needed to keep fuel tanks full. This is also good news for paper production efficiency, though I’m not aware of any connection between the price of Charmin and rioting in the streets. Continue reading
