Demand for corn-based ethanol is growing and that’s made farmland more valuable. This
year, American farmers planted 14 million acres more corn than they did last year. Some
small immigrant farmers believe that’s why they’re having a hard time finding land to rent
to grow fresh fruits and vegetables. Joel Grostephan reports:


Jenny Chang doesn’t want to change the government’s policy on ethanol subsidies. She
just wants some good land to raise her vegetables that she sells at the farmer’s market.
When planting time came around this year, she was still looking for a plot to rent. Chang is
Hmong and she came from Laos more than 20 years ago with few job skills. For
the last 7 years, she’s made part of her income from farming on land she rents. In the
past, finding land to rent wasn’t that hard. But, Chang says through her daughter who
interprets for her, this year was different:


“She said that this year, we couldn’t find land, that’s why we got stuck with this bad area.
She’s really sad.”


With corn selling for double what it did last year, land values are going up. That means
rent is going up. And the 300 Hmong farmers in this area are having a hard time finding
land they can afford.


Kent Olson is an economics professor at the University of Minnesota. He says he thinks
land scarcity is due to higher demand for ethanol:


“Your ethanol may have started the ball rolling, and created higher prices for corn, which
pushed corn onto other land from other crops but that’s pushed soybean prices up. So we
are seeing higher rent from a couple different directions.”


In theory, ethanol from corn is supposed to be good for the environment. It burns cleaner
and means less reliance on foreign oil.


But… conventional corn farmers rely on fossil fuel-based fertilizers and chemical
pesticides. By the time their diesel-powered tractors plant the corn, combines harvest it,
trucks transport it and ethanol distillery plants cook it, the energy gain from corn ethanol
is marginal.


The Hmong farm differently. Most don’t use fossil fuel-based fertilizers or pesticides.
Instead, they do a lot of hand weeding, and put in long days. Jenny Chang fertilizes her
tomatoes with chicken manure. Chang’s daughter, who is also named Jenny Chang, says
many older Hmong farmers are suspicious of chemicals:


“They like gardening the way they used to back in old Laos. They don’t really know what
insecticides and pesticides are, or how to use it so that’s why they just don’t use it. And a lot of
people are afraid of cancer, so they just like to grow things organically because they eat it
themselves.”


And researchers say growing food this way seems more environmentally friendly than
growing corn for ethanol.


Bill Moseley is a professor at Macalester College in St. Paul. He studies the
environmental effects of agriculture:


“Conventional corn production is displacing, in this particular case, a form of
agriculture that is more environmentally sound in terms of it’s using fewer fossil
fuel imports, and it’s producing crops for the local market, it’s particularly ironic in
this instance.”


Government officials don’t think increased corn production for ethanol is the problem.
Perry Aasness works with the U.S. Department of Agriculture’s Farm Service Agency. When he learned the Hmong farmers were having a hard time finding land to rent, his
agency helped them. But Aasness believes corn production for ethanol is NOT the cause
of the land shortage:


“Well, at least in Minnesota I think it’s very, very minimal. I think the real issue that I
have seen in Minnesota is that the Hmong farmers, the Hmong community is primarily
based in the Twin Cities metro area. They have to go further out to get land — a lot
of it I think is just due to urban sprawl.”


For many people in the Minneapolis-St. Paul area, the Hmong are the face of agriculture
at farmers markets. But since no government agency keeps track of their numbers, it’s
hard to know if their tradition of raising crops on small plots of rented land is going well,
or if ethanol and high corn prices are actually putting their small businesses in danger of.

Bumper Crops of Mosquitoes

With above normal rain in much of the country this spring mosquitoes have been heavier in many
areas. The quick warm up after a cool spring has also helped hatch out a lot of the pests. The
GLRC’s Lester Graham reports you only have to step out your door to see the result:


It’s not so much hot days, but the fact that the nights are warmer that’s helping the skeeter broods
hatch out in hordes. I’ve been painfully aware of the mosquitoes this year because I live right next
to a river in a year where there’s been plenty of rain to make little pools of stagnant water
everywhere. It’s a real nuisance.


(sound of mosquitoes)


“I’m in a very hot car and a lot of mosquitoes are trapped in here with me.
(pause) All these mosquitoes got here, just because I opened my hatchback and took
some groceries out, and they just swarmed in.”


(sound continues… smack!)


I don’t like ‘em much. Most people don’t have a very high tolerance for mosquitoes. They’ve
actually studied that. John Witter is a biologist with the University of Michigan who spends a lot of
time in the woods, studying bugs. He says there was a Michigan State University study that tracked
interaction of people and mosquitoes while camping.


“If you have more than about four mosquitoes landing on your body per minute, the people leave
the hiking trail. They go back to their campers because they just cannot handle that annoyance.
So, higher population numbers of mosquitoes, more bites, more annoyance.”


But not everyone, or everything, can get away from the pests. Jenny Barnett works at the Binder
Park Zoo in Battle Creek, Michigan. The zoo is in the middle of a forest. The mosquitoes love it
there.


(sound of birds)


The zoo’s tried to use different kinds of fumigation in past years, but with sensitive animals and birds
like the ones we’re watching there was a lot of concern; and really it just didn’t work.


“With 430 acres and a lot of it being wetland, we didn’t even make a dent on it. So, after a couple
of years, we stopped doing anything.”


The mosquitoes weren’t always that bad, and guests at the zoo didn’t seem to mind that much. A
little mosquito repellant and everyone was good to go.

Then along came West Nile virus. Like a lot of zoos, Binder Park put its birds inside – not good for
the birds – not good for the people who wanted to see the birds. A couple of years after West Nile
was detected, a vaccine that was developed for horses and it was used on birds, too. Jenny Barnett says it
seems to work.


“So far we’ve had success with it and we are continuing to do testing on their blood to check for
West Nile virus and we’ve been successful so far, but we will continue to vaccinate. We’ll
vaccinate our horses, and we’ll always worry about it, but a lot of the birds do have immunities right
now.”


And it’s assumed a lot of people also have immunity to the West Nile virus. They probably have been
infected and didn’t even know it. People with immune deficiencies are at much greater risk, but
many healthy adults can contract it and dismiss it as a summer cold or bad allergies, but health
officials say do what you can to avoid being bitten. Now, they’re not saying that you shouldn’t go
outside. They’re just saying if you do go outside, you should use a mosquito repellant with DEET.
Natasha Davidson is with the Health Department in Ingham County Michigan. She says don’t
douse yourself in repellant. A light spray will do.


“And if you’re applying it to your face, you should really put it on your hands first and then apply it.
And even applying it to children, it’s better an adult put on their hands first and then apply it to a
child.”


Davidson says don’t use DEET on children six months of age and younger, and don’t put it on
toddler’s hands because they’ll just put them in their mouths. Ugh… not good to ingest DEET.
Some advise using a cream based repellant because it doesn’t go into the skin as easily, and stays
on the surface where it can do some good. It’s also a good idea to wear loose fitting clothes with
long sleeves and long pants. I know it’s hot, but it beats scratching mosquito bites for days on end.
Natasha Davidson says even on heavy mosquito years like this one you can help reduce your
exposure to the pest.


“Other things that people can do is to make sure they have no standing water in their yard,
whether it’s at home or at a vacation property. Empty your gutters. Make sure that they’re clean
so that the water flows through. Make sure that you don’t have flower pots that have standing
water in it, old tires, different things like that. If you have a bird bath, change the water in the bird
bath once a week.”


Beyond that there’s not much you can do. Mosquitoes aren’t going away and with a little
preparation…


(sound of spray)


…you should just go ahead and enjoy the outdoors.

You might be seeing more mosquitoes this year. Conditions are right in many areas to see a
bigger than normal crop of mosquitoes. The GLRC’s Lester Graham reports:


The mosquito populations in a lot of places are high this year because of above normal rainfall.
Although you don’t hear as much about West Nile virus these days, it’s still a threat, especially
to those with compromised immune systems, particularly older people. Natasha Davidson is with
the Health Department in Ingham County, Michigan where there’s been a bumper crop of
mosquitoes lately. She says the best prevention is avoid getting bitten:


“Well, you want to make sure you’re wearing an insect repellant. And also when you’re outdoors
when mosquitoes are active been dusk and dawn, wear long sleeves; wear long pants; wear
socks. And apply the insect repellant to your clothing.”


So far there’s no West Nile vaccine for people. Researchers are working to come up with one.
They believe healthy people who’ve already contracted the virus and built up antibodies might be a
source for a successful vaccine in a couple of years or so.


For the GLRC, this is Lester Graham.
