Unstrange maps: Security, health, economics

September 3, 2007

Strange Maps features odd maps, often fictional. I like the site, especially for the inherent humor in some of the maps — and since it’s such a popular site among the more than 1 million WordPress weblogs, it’s clear others share my enthusiasm.

Global map of energy security risk - Maplecroft Maps

There are a lot of unstrange and beautiful maps based on reality, too, used to give a quick, graphic image to the brains of people working on serious problems. Maps guide policy makers, and illustrate geographical range of problems, and sometimes geographical causes and vulnerabilities.

Here’s a source of interactive maps that every economics, government, history, and health teacher should bookmark: Maplecroft Maps.

Maps at this site cover a nearly complete range of issues that worry leaders of businesses and nations. I found the site looking for information about malaria.

Of special note is the wealth of information available from the interactive features. Clicking on nations or on symbols on the map provides details of issues the map covers; three tabs with the maps take the viewer of most of the maps to an extensive list of resources on the issue, and case studies, and analysis. These sources seem tailor made to help students doing geography projects.

Issue maps include disasters, malaria, child labor, climate change, poverty, land mine risk, political risk and a wide variety of others. You’ll need Macromedia Flash on your computer; there does not appear to be any way to download the maps, so you’ll need a live internet link to use these in class.

Information from these maps will be more current than any geography, history or economics book. Go see.

Maplecroft is a network of academic and business consultants. These maps are made to help their clients; Maplecroft’s description of the series is below the fold.

Slave narratives in Flash animation

August 31, 2007

Wow!

Graphic for Slave Narratives on-line exhibit

Teachers, take a look at this Flash animation about slavery, from the Museum of African Diaspora (MoAD) in San Francisco. Yes, that beautiful, distinctive narrator voice is Maya Angelou — this is a high quality, high-impact presentation.

This MoAD piece, “Slave Narratives,” gives a glimpse of the potential of on-line learning, and what can be done with computers to supercharge a subject. Here slavery is presented as not only a colonial American problem, but is instead carried on through salvery issues in the 21st century. It’s part of the MoAD “Salon,” a site that world geography, world history and U.S. history teachers need to visit right away.

Cyberspace Nova discusses the site in a quick review of recent great Flash animations:

Imagine how it looked like taking a people freedom, torturing them, killing them and moving them far far away from their home. Tears can follow very easily if you just put one picture on your mind how it looked like. Yet, Slave Narrative put thousands of pictures in front of your eyes if you listen to the stories of slaves who lived to write them and share with people that will live after them. Let’s never forget this, because it’s happening today, like some stories from Slave Narratives tell… I love that this site is done in Flash, it is so powerful, it tells a story that we cannot hear a lot… Narrative part not just only justifies use of Flash, whole interactivity makes it great. 5/5

Opening to Photographs from the African Diaspora exhibit

Also look at this photographic exhibit of from MoAD, featuring more than 2,000 photos of people of African descent and places and things important to them — again, with great flash animation.

Giant spider community – in Texas, of course

August 30, 2007

Bug Girl has all the details — spiders being closer to her blog’s core topic — but this news is just about 90 minutes from here, much closer for North Dallasites.

Giant web at Lake Tawakoni State Park, Texas - Star-Telegram photo

Did you see the giant web at Lake Tawakoni State Park? It was on the CBS Evening News tonight, and it’s all over the blogs today. The Washington Post has this delightful quote (delightful to those of us who think of all the West Nile virus that won’t be spread):

“At first, it was so white it looked like fairyland,” said Donna Garde, superintendent of the [Lake Tawakoni State] park about 45 miles east of Dallas. “Now it’s filled with so many mosquitoes that it’s turned a little brown. There are times you can literally hear the screech of millions of mosquitoes caught in those webs.”

Ah, the screech of millions of mosquitoes, about to be eaten.

Map to Lake Tawakoni State Park, from Dallas

By the way, DDT kills these spider very well. DDT spraying, in such a case, is a favor to the mosquitoes — spiders can be significant contributors to pest control.

See Bug Girl’s post for all the science — her post is practically a lesson plan just waiting to be downloaded.

And, it’s pronounced tuh-WOK-uh-nee. Named after a local tribe of Native Americans, “a Caddoan tribe of the Wichita group.”


How to fight malaria – Kenya’s example

August 17, 2007

Kenya has cut malaria by nearly half. Without further comment from me, here’s the news story from Gulf Times, Doha, Qatar, and below that, from a few other sources:

Kenya nearly halves child deaths from malaria

Published: Friday, 17 August, 2007, 01:27 AM Doha Time

NAIROBI: Kenya announced yesterday that it almost halved malaria deaths among small children by using insecticidal nets (INTs), spurring the World Health Organisation (WHO) to advocate free nets for all as it tackles Africa’s deadliest disease.

Health Minister Charity Ngilu said distribution of 13.4mn INTs over the past five years among children and pregnant women had helped curtail infections, a key success against a disease threatening 40% of the world’s population.

“Childhood deaths have been reduced by 44% in high-risk districts, in-patient malaria cases and deaths are falling (and) there are reduced cases at the community level,” she said in a statement.

“For every 1,000 treated nets used, seven children who might have died of malaria are saved.”

Malaria kills 34,000 children under the age of five each year in Kenya, and threatens the lives of more than 25mn of its population of 34mn people, the ministry said.

Children sleeping under INTs in malaria risk areas are 44% less likely to die than those who are not, according to a survey carried out in four districts representing the country’s epidemiological pattern.

The government has distributed 12mn doses of artemisinin-based therapy (ACT), the latest surefire anti-malaria drug cocktail to replace the mono-therapies that had developed resistance.

In addition, some 824,600 houses in 16 epidemic-prone districts underwent indoor spraying this year.
The government and donors spent 4.7bn shillings ($70.2mn) for the campaign, yet the funds were not enough.

Ngilu said the government would freely provide 2mn treated nets annually to ward off mosquitoes at night when they are active, calling on donors to boost the blanket distribution.

“The impact we have seen and the lessons we have learnt through massively distributing INTs, rather than selectively marketing and selling them, will not only benefit Kenya’s children but all Africa’s children,” she said.

In a statement, the WHO said it had abandoned its earlier guideline of targeting only vulnerable groups – under fives and pregnant women – in favour of “making their protection immediate while achieving full coverage”.

“Recent studies have shown that by expanding the use of these nets to all people in targeted areas, increased coverage and enhanced protection can be achieved while protecting all community members.”

WHO chief Margaret Chan said that Kenya’s success “serves as a model that should be replicated throughout ‘malarious’ countries in Africa.”

“This data from Kenya ends the debate about how to deliver the long-lasting nets. No longer should the safety or well-being of your family be based upon whether you are rich or poor,” said WHO’s Global Malaria Programme director Arata Kochi.

Chan and Kochi were deriding the “social marketing” model widely backed by donors of distributing INTs by selling them at subsidised rates, even to vulnerable groups, and raising awareness of their importance.

Although supporting anti-malaria campaigns, public health watchers have chided British and US foreign development agencies for pushing for social marketing in the world’s poorest continent.

The WHO launched a global programme in 1955 to eradicate the disease that has frustrated attempts to create a vaccine owing to its constant mutations.

Using dichloro-diphenyl-trichloroethane (DDT), a powerful insecticide, and the drug chroloquine, the organisation managed to eradicated the disease in the West by the 1960s.

But the programme never got off the ground in the humid and low-lying tropics in sub-Saharan Africa where the disease persisted.

By 1969, the programme collapsed as financing withered in the face of rising poverty, political upheavals and surging opposition to DDT for misuse, not by anti-malaria campaigners, but farmers.

But Kochi said the Stockholm Convention on Persistent Organic Pollutants allowed the use of DDT in endemic countries for “public health only” and Uganda and Malawi were the only African nations keen on the chemical.

Malaria affects more than 1bn people worldwide and kills 1mn – mainly under age five – every year, the vast majority in sub-Saharan Africa. – AFP (Agence France Press) Read the rest of this entry »


Berlin Wall’s 46th

August 13, 2007

Today is the 46th anniversary of the beginning of the Berlin Wall. The post I wrote last year on this topic continues to be popular, day in and day out, but especially when high school curricula get to the Cold War, the Berlin Airlift, the 1960s, and the collapse of the Soviet empire, best exemplified by the destruction of the Berlin Wall itself and the reunification of Germany.

Go read my post of last year, “Berlin Wall’s 45th.”

The photograph I used to illustrate that post has become one of the more popular photos of the Berlin Wall on the internet. It is from a small, too-little used collection posted by Corey Hatch at the University of Utah.

Here is another photo from his collection. It comes without caption; from the barbed wire and the uniform and helmet, I would say This is cropped version of a photo of an East German soldier,  Conrad Schumann , assigned to shoot people trying to breach the wall to escape to West Germany, who instead decided to leap to freedom himself, probably at Checkpoint Charlie, one of three gates between East and West Berlin. I regret I have no further credit information on the photo on August 15, 1961.  The photo is by West German photographer Peter Leibing, then working for Contiepress, in Hamburg.

East German soldier leaping barbed wire of the Berlin Wall, to freedom.

German authorities announced the Wall was open for travel between the two entities of divided Germany on November 9, 1989. Jubilant Germans on both sides of the wall tore down sections, poked holes in the concrete barriers, and generally vandalized the wall over the next few weeks. Negotiations then led the way for the Reunification of Germany on October 3, 1990.

A Scout is . . . Friendly, Courteous, Kind . . . Reverent: 100 years of Scouting

August 4, 2007

Scouts at the World Jamboree renew their oaths, Wednesday, August 1, 2007

  • Scouts from many nations renew their oaths, August 1, at Brownsea Island, off the south coast of England — the 30th World Jamboree of Scouting, marking the founding of Scouting 100 years ago. Photo by Ron Neal, AFP/Getty Images.

The rowdies who like to claim all shows of manners are just ‘wussy PC boojum’ got their knickers all atwist because Scouts at the 30th World Jamboree eat vegetarian.

Why not? It’s a World Jamboree. If the menu that best fits Scouts from 80 nations is vegetarian, why not? In the U.S., the fourth, fifth and sixth points of the Scout Law are “Friendly, Courteous, Kind.” If the menu offends a quarter of the Scouts, can they live up to those three points of the law? What about the twelfth point, which says a Scout is Reverent, especially to the religious views of others?

Here’s the post that set me off, at Innocent Bystanders.  (And here’s the same sort of bluster at a very Scout-unfriendly site — warning, site contains cheesecake NSFW.)

Here’s the news story from ThisIsLondon.com that probably inspired that post: “Scouts banned from eating burgers and bangers — because of religious belief.”

Here’s the AP story in the Bryan-College Station Eagle, in Texas, that notes the fire ban at the Jamboree:

LONDON – Scouts around the world celebrated the 100th anniversary of their movement Wednesday, but those at its birthplace couldn’t show off one of their fundamental skills – firebuilding.

While observances took place from the Kingdom of Bhutan to Ecuador, the symbolic focus was on Brownsea Island, off the coast of southern England. That’s the site where Robert Baden-Powell organized a camp for 20 boys that developed into the worldwide Scouting movement.

Baden-Powell, a lieutenant-general in the British army, organized that camp to teach boys outdoor skills and physical fitness. He detailed the experiences in a book called Scouting For Boys, and the movement gained footing when boys organized themselves into groups, persuaded adults to become their leaders and used Baden-Powell’s ideas as the basis for camps, treks and other activities.

Older girls were allowed to join during the 1970s. Membership was extended to all girls, ages 6 to 25, in 1991.

“When [Baden-Powell] first ran the camp, he brought together different social classes from public schools and less fortunate backgrounds,” said scout Jon Grimes, 19. “It was about crossing the social divide and making friends. Our camp this year will be about making friends between people from different cultures.”

But unlike Baden-Powell’s boys, today’s Scouts are banned from lighting campfires on Brownsea Island. The National Trust acquired the island in 1962 and forbids fires in order to protect the wildlife.

The campfire ban did not dampen the spirit of the 300 Scouts on Brownsea Island who celebrated the centennial canoeing, hiking, making pottery, learning archery and participating in workshops.

Our troop, Troop 355, didn’t send anyone to the World Jamboree, but five boys have already attained their Eagle rank this year — we had an Eagle Court of Honor this afternoon. Scouts devised several interesting ways to celebrate the 100th anniversary of Scouting, regardless of where they are:

Some centennial celebrations began as early as Saturday, when Prince William opened the 21st World Scout Jamboree, in eastern England, with 40,000 youngsters from more than 160 countries.

Scouts from around the world are taking part in events. About 1,000 Scouts are cooking a huge campfire breakfast in Namibia, and groups from all over Malawi will be camping at the top of Mulanje mountain, one of the highest peaks in Africa.

Scouting in the U.S. marks its centennial in 2010.

Saving Texas’s only natural lake

August 3, 2007

Aptly named, Salvinia molesta threatens to choke Caddo Lake to death. As Caddo Lake is the only natural lake in Texas, and a site of outstanding beauty and great natural treasure, the friends of Caddo Lake are fighting back.

Spraying Salvinia molesta on Caddo Lake - NY Times photo by Michael Stravato

The New York Times features a lengthy story on the lake and the fight to save it in this week’s Science section (July 31, 2007 – Science is part of the Times every Tuesday).

Every Texas social studies teacher should know Caddo Lake and its stories as well as anything else. It’s the stuff memorable classes are made of.

1. It’s the only “natural” lake in Texas, though it is formed by a dam. The “only honest lake in Texas,” in the local lingo. The original lake was formed by a monumental log jam on the Red River, probably trees blown down by a massive hurricane several hundred years ago.

2. Caddo Lake is named after the Caddo Tribe, the tribe whose word for friend, “tejas,” gave the state its name. (See my earlier post on Caddoland.)

3. Caddo Lake straddles what was once “no man’s land,” or the Neutral Territory, a buffer zone between English/French, then American, and Spanish, then Mexican settlements. It was a haven for criminals, scalawags, filibusterers and revolutionaries. The area plays a large role in the decades of fighting to steal Texas from the Spain, and later from Mexico. Texas history is much better understood when one knows the lake.

4. Caddo Lake once was the means to make Jefferson, Texas, a port city. Until Col. Shreveport dynamited the logjam that made the lake in 1873, Jefferson was a bustling center of commerce. Today Jefferson boasts some wonderfully preserved historic remnants of that era, many converted to bed and breakfast inns, a great weekend getaway. Fishing is good, photography is great.

5. Ladybird Johnson was born nearby, and her family still lives in the area.

6. The Hughes Tool Company had its beginnings on Caddo Lake, where Howard Hughes, Sr., tested his drill bit, “the rock eater,” designed to cut through mud and rock to where the oil was; this is the home of the fortune that Howard Hughes, Jr., inherited, to build to one of the greatest fortunes in the world. That the younger Hughes was a rake, a mechanical genius, an air pioneer, daring movie producer, and weird as hell only makes the story better. Hughes named his movie production company after the lake, Caddo Productions.

6. Contrary to most of Texas’s political leanings, local people around Caddo Lake have rallied to efforts to protect the lake and conserve its rare beauty. The area is designated for protection as a Ramsar Treaty critical wetlands site — a designation that most conservative Texans ridicule and fear (at one point the Texas Republican Party platform opposed conservation easements to protect the lake bizarre). Latter-day Caddoans welcome the designation, and when we toured the area they sang the praises of Don Henley, the rock and roll musician who is aiding their efforts to save the lake. It’s an odd combination for any political work — uniquely Texas. (Here’s your chance to play the Eagles for your classes, teachers!)

7. When it comes to Texas botany, zoology, and biology in general, Caddo Lake provides the local angle for water quality, water shortages (one proposal is to steal water from the lake for Texas cities far away), wildlife management, and of course, the invasion of exotic species.

8. Everything about this area screams Texas quirkiness. Uncertain, Texas? An often-told story (accurate?) is that when the town applied for a post office, there was a dispute about what to call the town. The fellow who filled out the application wrote “uncertain” in the blank for the town’s name — and that’s how the U.S. Postal Service approved it. Another story holds that the name “Uncertain Landing” caught on because the landing was treacherous mooring for boats. You got a better story about your town’s name? I doubt it.

Save the article from the Times, teachers! You’ll be glad you have it later this year.

Disasters!

August 2, 2007

Popular Mechanics features the “Ten Worst Disasters of the Century,” showing how Americans fought back after natural disasters in — roughly — the 20th century.

It’s an odd century used — it leaves out the Galveston, Texas, hurricane disaster of 1900, but it includes Hurricane Katrina in 2005 (maybe it would more accurately be titled “disasters of the last 100 years”). The list is limited to natural disasters, so the Texas City harbor disaster of 1947 isn’t even considered, and the New London, Texas, school explosion doesn’t make the list. Those are quibbles; Texas teachers, and others, can supplement the list to accommodate other local, national and man-made disasters.

The Dust Bowl, which I would argue was greater than any of the other disasters listed, is also left off — too long a disaster?

The Popular Mechanics list is still a treasure trove for geography and history teachers. You might want to go out today to find the magazine at a newsstand, and pick up a copy or two. Throughout this post I sprinkled several links to the website of Popular Mechanics.

Here is the Popular Mechanics list of top 10 natural disasters, in chronological order:

1. 1906 San Francisco Earthquake

2. The Big Burn of 1910

3. 1918 Spanish Flu Epidemic

4. Tri-state tornado of 1925 (one tornado across Missouri, southern Illinois and Indiana)

5. The New England Hurricane of 1938

6. The Great Alaskan Earthquake and Tsunami of 1964

7. 1974 Super Tornado Outbreak

8. Mt. St. Helens Eruption, 1980

9. 1993 Storm of the Century (snow)

10. Hurricane Katrina, 2005

There you have ten disasters of the 100 years between 1905 and 2005. For a geography or history class, that could be ten days of study — a map each day, a history timeline each day featuring especially who was president at the time (and how the president reacted), a story of geology or meteorology or public health each day. At the end of a ten-day unit the class could have made ten different maps covering most of the U.S. but Hawaii, covering the technology developments of the 20th century, especially the development of radio, air travel, and space technology (weather satellites), and covering the development of human institutions to cope with disasters and prevent future disaster, especially communication, transporation, medical care, banking and other investments (the rise of the Bank of America from the San Francisco Earthquake is a great little piece of history all by itself), and government.

This is not the curriculum most of the state testing authorities envision. Students will remember the geography, history and technology of these ten days with a lot more clarity and depth than most other units a teacher might cover.

Alternatively, these could be ten Disaster Fridays, reinforcing geography and history in particular. I’m sure I’ve just scratched the surface — how do you use disasters, especially these ten, in your classroom now? Tell us about it in the comments, please.

Other disasters?

No rule says you have to stick with ten, or that you need to stick with the 20th century, or with natural disasters. Here are several other disasters that you may want to include in your curricula, again in chronological order:

The Great Chicago Fire of 1871 (October 8), which every school kid ought to know about; coupled with the fire in Peshtigo, Wisconsin, the same night, which was the deadliest fire in American history; news was slow to get out because nearly every person in Peshtigo died, and the town was literally burned off the map.

The blizzards of 1888 — the Schoolhouse Blizzard of January 12, which killed more than 200, mostly school students, and the Great Blizzard of 1888 which paralyzed much of the nation a couple of months later, from March 12 to March 14.

The Johnstown Flood, May 31, 1889 — a disaster seriously compounded by the folly of men and a leaky dam.  2,200 dead.

The Galveston Hurricane of 1900, memorialized in the best-selling history Isaac’s Storm. At least 8,000 people died in Galveston, Texas’s largest city — and maybe as many as 15,000. There were too many bodies to count. Galveston invented a new form of government to help recover from the storm, the city commission style of government, which has been adopted widely throughout the U.S. Another large hurricane struck Galveston in 1915, killing 235 people — but it was so small in comparison, it is usually forgotten.

The 1909 Cherry Mine Fire (Bureau County, Illinois) — 259 men and boys died in a coal mine fire.

Dawson, New Mexico, Mine Disaster, October 22, 1913. 263 dead.

The Sinking of the Steamer Eastland on Lake Michigan, July 24, 1915. 840 people died.

The Boston Molasses Disaster of 1919, which featured walls of hot molasses 35 feet high careening through the streets of Boston — 21 died.

The Tulsa Riot, 1921 — a race riot that killed 300 people and destroyed the African American “Wall Street.”

The Great Mississippi Flood of 1927, which shook the social and civic foundations of riverside cities and towns.

The Dust Bowl, 1931-1939

The Ohio River Flood of 1937, which killed over 200 and pushed a million people out of their homes.

The New London, Texas, School Explosion, March 18, 1937.  In Texas’s richest school district, a gas pipeline heated the building for free.  In the era before odorfactants were added to natural gas to alert people of leaks, no one suspected the leak.  Nearly 300 died in the explosion, mostly children.

The 1946 Aleutian Islands Earthquake and Tsunami, and the April Fools Tsunami in Hawaii. An earthquake registering 7.8 struck the Aleutian Islands in far western Alaska. Six people died there. 159 people died in Hawaii when the resulting tsunami struck several hours later — the death toll perhaps increased because many people thought the warnings of a coming wave to be an April Fool’s prank.

The Texas City Explosion, 1947

The Montana-Yellowstone Earthquake, 1959, a 7.3 shaker which killed 28 people and created a new lake, Quake Lake, on the Madison River.

The Watts Riots, August 1965.

The Detroit and Newark Riots, 1967. Yes, it was “the Summer of Love.” Still, there were 164 “civil disorders” (riots) in 128 different U.S. cities. Detroit and Newark were the worst.

The Yellowstone Fires, 1988.

The Great Flood of 1993 (Mississippi River).

The 1997 Red River Flood (North Dakota, Minnesota and Manitoba, Canada).

Good heavens. That’s a depressing list. Still, I wonder — have I left anything off? Tell me in the comments, if you see something missing.

Tracking hurricanes for classrooms

Here in North Texas, most of our classrooms see refugees from coastal storms from time to time — in fact, most schools still have refugees from Hurricane Katrina, or Hurricane Rita. Plus, sitting close to Tornado Alley, everyone understands that weather is no abstraction here. Weather is personal.

Maps of weather offer teachers a good way to make geography personal, too — or at least more relevant. Those little clouds swirling west from the coast of Africa today could be the hurricane that swamps the Texas coast in a couple of weeks.

An e-mail correspondent sent a link to the Weather Channel’s Hurricane Central, suggesting I might want to track storms for my personal safety (Tropical Storm Chantal is far off in the Atlantic, and racing away; no problems from that storm).

Why not have kids track storms in class? The map above, for example, should be a basic foundation for much of Texas history (the explorers and Spanish colonization, for example), for U.S. history (explorers and the slave trade, the Triangle Trade, the Battle of the Atlantic in World War II, and so on). Get students used to using maps to track important and interesting things, and map use will become second nature, as it should be. The Weather Channel and other sources create updates on that basic map several times a day.

What sorts of storms did the explorers face? The slave ships? How big was the storm that shipwrecked Esteban in Texas? What is one likely source of the massive forest blowdown that created the greater Caddo Lake?

Hurricane season runs through October. There should be a lot of grist for the learning mill just in the daily weather reports. You might also use the weather maps in the daily newspaper (most local newspapers will give you a classroom set for a week for under $20.00 under the Newspapers in Education (NIE) project) (NIE offers an interactive quiz on geography weekly, by the way).

Is there any kid who isn’t fascinated by the weather? That’s your hook. Maps are freely available from the Weather Channel site, and from dozens of others.

Caption from NASA: The third tropical depression of the Atlantic hurricane season formed around 11:00 p.m. EDT on Monday, July 30 west of Bermuda. Exactly 12 hours later on Tuesday, July 31, at 11:00 a.m. EDT, the storm strengthened into a tropical storm with sustained winds of 40 mph and higher gusts. At that time, the storm was named Tropical Storm Chantal. Chantal was located near latitude 40.2 north and longitude 62.7 west, about 330 miles (530 km) south of Halifax, Nova Scotia and is moving rapidly toward the northeast near 23 mph (37 km/hr). Chantal is not a threat to the United States.

BBC animation: The Western Front, World War I

July 30, 2007

Western Front of World War I, from BBC animation

Here’s another map animation from the BBC that helps people visualize the stalemate nature of the Western Front of World War I.

If this animation is available in any form for purchase from the BBC for classroom use, I haven’t found it. I do wish the BBC would do a DVD or CD compilation of these animations and make it available at very low cost to teachers (high costs mean schools buy only one copy, which teachers can’t get a chance to see, and consequently won’t integrate into their lesson plans; paradoxically, a low-priced disk would probably earn BBC more money, and certainly would contribute to much more classroom learning).

This would be a good link for individual study at home on the internet. A great lecture could be built around it, if one has internet access live in the classroom and a way to project it.


Collateral damage from magic bullets

July 22, 2007

In an earlier post I noted Norman Borlaug’s receiving the Congressional Gold Medal. In comments, Bernarda noted those who disagree with the claim that Borlaug’s Green Revolution was much of a benefit, or perhaps more accurately, those who note the problems that result from such advances — and there are many. Bernarda pointed to a BBC lecture from Vendana Shiva, detailing the problems that Punjab experienced as a result of governmental and society structures unable to deal with the changes required by high-yield crops: “Poverty and Globalisation.” It’s worth a read or a listen.
Similarly, in another BBC lecture in that series, Gro Harlem Bruntland details problems from “progress” that includes cutting the forests, in “Health and Population.” Relevant to other discussions here, she notes a rise in malaria due to deforestation, raising an issue that the junk science purveyors opposed to Rachel Carson’s honoring would like to ignore. Here is a small excerpt of her talk — note that deforestation is not a problem that more DDT can solve:

Gro Harlem Bruntland:  Recently, in Mozambique, I saw children with their eyes glazed with fever from a malaria that could have been prevented if their parents could afford bed nets. Deforestation had changed malaria from a nuisance to a curse in a matter of twenty years. 

Gro Harlem Brundtland, former Director General of the World Health Organization (WHO). Wikiquote image.

Gro Harlem Brundtland, former Director General of the World Health Organization (WHO). Wikiquote image.

More people are suffering from this killing and debilitating disease now than ever before, and deforestation, climate change and breakdowns in health services have caused the disease to spread to new areas and areas that have been malaria-free for decades, like in Europe.

In the Philippines, I have watched how beggars sit exhausted on the pavements convulsed with coughing. Tuberculosis, which we long believed had been brought under control by effective treatment, is on the rise again. Increasingly, we see forms of tuberculosis which are resistant to all but a very expensive cocktail of drugs.

I think that HIV/AIDS may be the most serious threat to face sub-Saharan Africa and other developing regions. space. Already, the AIDS epidemic is the leading cause of death in several African countries. AIDS has reversed the increases in life expectancy we have seen over the past thirty years. The social and economic devastation in countries that could lose a fifth of their productive populations is heart-rending.

I believe we are facing this alarming situation largely because of an outdated approach to development. Our theories have to catch up with what our ears and eyes are telling us – and fast.

There was a period in development thinking – not so long ago – when spending on public services, such as health and education, would have to wait. Good health was a luxury, only to be achieved when countries had developed a particular level of physical infrastructure and established a certain economic strength. The implicit assumption was that health was to do with consumption. Experience and research over the past few years have shown that such thinking was at best simplistic, and at worst plainly wrong.

I maintain that if people’s health improves, they make a real contribution to their nation’s prosperity. In my judgement, good health is not only an important concern for individuals, it plays a central role in achieving sustainable economic growth and an effective use of resources.

As in Europe at the end of the 19th and beginning of the 20th century, we have seen that developing countries which invest relatively more, and well, on health are likely to achieve higher economic growth.

In other words, malaria prevention grows on trees, or malaria grows with the cutting of trees.


Not reading for comprehension: Glenn Reynolds, National Geographic and DDT

July 17, 2007

It’s best to avoid the tabloids most of the time, but particularly its good not to rely on tabloids for good information for making policy.

Glenn Reynolds at Instapundit, often an internet tabloid, demonstrates these dangers, especially with regard to the hoax campaign against Rachel Carson and the World Health Organization.

In a post today, Instapundit said:

A REPORT ON MALARIA, from National Geographic.

And note this bit:

Soon after the program collapsed, mosquito control lost access to its crucial tool, DDT. The problem was overuse—not by malaria fighters but by farmers, especially cotton growers, trying to protect their crops. The spray was so cheap that many times the necessary doses were sometimes applied. The insecticide accumulated in the soil and tainted watercourses. Though nontoxic to humans, DDT harmed peregrine falcons, sea lions, and salmon. In 1962 Rachel Carson published Silent Spring, documenting this abuse and painting so damning a picture that the chemical was eventually outlawed by most of the world for agricultural use. Exceptions were made for malaria control, but DDT became nearly impossible to procure. “The ban on DDT,” says Gwadz of the National Institutes of Health, “may have killed 20 million children.”

Read the whole thing. [Emphasis from Instapundit.]

“Malaria: Stopping a Global Killer,” cover of National Geographic Magazine, July 2007. Test to see if your reading comprehension is better than Instapundit’s Glenn Reynolds!

Please do read the whole thing — what is emphasized is not what the brief snippet at Instapundit says at all. The National Geographic article, “Bedlam in the Blood,” gives details of the fight against malaria, including details about how difficult it is to beat. Among other things, the article talks about the medical difficulties and the political difficulties. The article emphasizes that there is not a panacea solution, including especially DDT.

But, that paragraph Reynolds quotes already carries that message. Did you miss it? Reynolds appears to have missed it big time. Here’s the paragraph again, with my emphasis for what you should understand about the difficulties

Soon after the program collapsed, mosquito control lost access to its crucial tool, DDT. The problem was overuse—not by malaria fighters but by farmers, especially cotton growers, trying to protect their crops. The spray was so cheap that many times the necessary doses were sometimes applied. The insecticide accumulated in the soil and tainted watercourses. Though nontoxic to humans, DDT harmed peregrine falcons, sea lions, and salmon, [especially predators of mosquitoes]. In 1962 Rachel Carson published Silent Spring, documenting this abuse and painting so damning a picture that the chemical was eventually outlawed by most of the world for agricultural use [years later]. Exceptions were made for malaria control, but DDT became nearly impossible to procure. “The ban on DDT,” says Gwadz of the National Institutes of Health, “may have killed 20 million children.”

In the critical area of Subsaharan Africa, governments were unable to put together programs to spray for mosquitoes and deliver pharmaceuticals to victims. Although DDT was largely ineffective against the mosquitoes that carried some forms of the disease in that area, the human institutions simply did not exist to make an eradication program work.

Instapundit puts the blame on Rachel Carson, as if the later restrictions on DDT were what she urged, and as if Carson could personally have saved the Belgian Congo, Rwanda, Rhodesia/Zimbabwe and other nations from revolutions that crippled governmental efficacy throughout Africa.

Read the entire article. Malaria eradication in the U.S. was made easier by the fact that the mosquitoes that carry the disease here tend to eschew humans for meals — they bite cattle instead (who have their own forms of malaria). The U.S. had money to put screens on windows, a medical establishment to treat malaria, and the less aggressive form of the malaria parasites.

Subsaharan Africa had none of those advantages. Reynolds suggests, and the Competitive Enterprise Institute says, all of that was Rachel Carson’s fault.

The power of a bad, wrong idea should not be underestimated. Malaria cannot be conquered today without a combination of better medical care, education, strong governmental agencies to carry out government malaria-fighting programs, and consistent work to prevent evolution of malaria parasites into tougher diseases, or malaria-carrying mosquitoes into pesticide-resistant weapons of disease dissemination.

If Reynolds were to actually read Silent Spring, he’d begin to understand the enormity of the problems, and he could become a tool to stop the spread of malaria, instead of a voice unwittingly calling for surrender.

DDT is not a panacea against malaria now. Insects are resistant, the parasites are resistant to medical treatment (and DDT never played a key role in that process), money is scarce for creating and distributing effective blocks to malaria infections, and political institutions to fight the disease are wobbly. None of that is Rachel Carson’s fault. Much of that information was carried in the warnings from Rachel Carson.

But, if you read the article, you understand that DDT never could have been effective against some of the worst forms of malaria. DDT was never a panacea against malaria.

You won’t learn that from tabloid journalism, which offers solutions to difficult problems which are, as Ronald Reagan described them, simple and easy, but also ineffective and wrong. Instapundit misleads with such reports.

Quote of the moment: Immigration and economic growth

July 15, 2007

Immigrants’ Contribution to Economic Growth
“The pace of recent U.S. economic growth would have been impossible without immigration. Since 1990, immigrants have contributed to job growth in three main ways: They fill an increasing share of jobs overall, they take jobs in labor-scarce regions, and they fill the types of jobs native workers often shun. The foreign-born make up only 11.3 percent of the U.S. population and 14 percent of the labor force. But amazingly, the flow of foreign-born is so large that immigrants currently account for a larger share of labor force growth than natives (Chart 1).”

Four Stone Hearth 18

July 12, 2007

More catching up: 4 Stone Hearth 18 is up over at Clioaudio — a carnival of blog entries on “Archaeology, Biological Anthropology, Linguistics and Social Anthropology.” Some excellent entries, and even a reference back to the Caddoland map I noted a week or so ago.

4 Stone Hearth on iPod, by Beej Jorgensen

The entries on use of computers during class are useful. This one seems to have a lot of material for world geography and world history, but it’s stuff any social studies teacher should have available as a resource.

Don’t go blind, as Tom Boswell’s father told him when he turned Tom loose in the Library of Congress’ room on baseball.

Buy a piece of a National Forest, help fund schools

July 8, 2007

I’m trying to figure out how to use this amazing spectrum of maps in class.

But, one set can do something good for schools:  You can buy a piece of a national forest, and thereby contribute to a fund to help schools.  It’s a bit of a crackpot idea, really — selling off the national forests to provide a minuscule amount of money for schools.  But there may be some gems of land out there that could be used for  .  .  . decreasing global warming by creating a preserve for trees.

Davey Crockett National Forest, parcels for sale:  This map shows land in Texas for sale.

Your local National Forest may be represented, too.  Get there before the developers?  Not likely — but you can dream, can’t you?

Please be warned, though, I find the site a real memory hog.  If you’re running several programs, and you’re memory deficient as I appear to be for this set of maps, be careful.

Seriously, the site offers a variety of maps of public lands under the jurisdiction of the Bureau of Land Management and National Forest Service.  Mineral leasing, oil and gas, coal, and other resources are mapped.  This affects the western public lands states mostly, but it could be a great source for a geography project on energy or mineral or timber resources for the nation.

What do you think?
