Extinct and unmourned

From The Economist (Jul 6th 2009)

A database of endangered creatures fails to list those most at risk

ONE of the problems facing nature conservationists is that they often have little idea what is being lost. The places where flora and fauna flourish are frequently remote, inaccessible or both. It is one thing to know that the Amazonian rainforest or the seas off the Sahara desert are threatened. It is quite another to know which species in those ecosystems will be lost if they are badly damaged. The recent launch of a database containing details of creatures threatened with extinction is supposed to change that, but the task looks daunting.

When nature conservation first became a popular cause, in the early 1960s, one of its champions was Peter Scott, a British naturalist, artist and Olympic yachtsman, and son of the ill-fated polar explorer Robert Falcon Scott. He decided to draft lists of endangered species, known as the Red Data books, for a body called the International Union for the Conservation of Nature. Letters were sent from the union’s base in Morges, Switzerland, to naturalists, asking them to to assess the status of different species of animal and to grade them into one of five categories: very rare and getting rarer; less rare but threatened; stable; unknown; and formerly rare but now no longer in danger.

In due course particulars about many species arrived in Morges. These concentrated on what conservationists now call “charismatic” species: apes, lemurs, marsupials, parrots, polar bears, turtles and whales. Their global numbers were duly recorded along with their degree of endangerment, the state of their habitats and details of measures being taken to protect each species. It may have been scientific but it was also a very bureaucratic way of identifying where action was needed.

In June the Zoological Society of London launched an online version of Scott’s books. It unpicks the existing global lists held in Morges and examines them at the national level. It should thus be possible to identify which species are at risk of extinction within any given country’s borders. The database contains details of more than 50,000 species in 40 countries and regions, such as the Baltic Sea.

That may sound impressive, but it is not. It demonstrates that whole swathes of the world have been left unexamined. Countries missing from the list include some of the world’s most biodiverse nations, such as Indonesia and Madagascar. Even Brazil, with its Amazonian rainforests, is absent. Just six countries in the Americas are identified as containing endangered species, along with nine in Africa, nine in Europe and 11 in Asia.

The list’s sparsity shows that in the parts of the world where biodiversity is greatest and conservation planning is most important, conservationists lack the information with which to prioritise their efforts. These are the places where extinctions are likely to be occurring most rapidly, and species are probably disappearing without their existences ever having been documented.

The Convention on Biological Diversity, an international treaty that was adopted in Rio de Janeiro in 1992, was supposed to encourage the 191 countries that signed it to develop national strategies for the conservation and sustainable use of their biological diversity. A decade later a target was set to halt the decline in biodiversity by the end of 2010. Your correspondent suspects that it will be impossible to demonstrate whether or not that target has been achieved, if only because no one knows how many species there are on the planet.

FY 2007 Greenhouse Gas Emissions in Japan

Japan's GHG emission in FY2007 totaled 1.374 billion tonnes of carbon dioxide (CO2) equivalent. The figure is 2.4% higher than the previous year and 9.0% higher than the base year of the Kyoto protocol.

Don’t Waste Time Cutting Emissions

By BJORN LOMBORG, From the NY Times of April 24, 2009

WE are often told that tackling global warming should be the defining task of our age — that we must cut emissions immediately and drastically. But people are not buying the idea that, unless we act, the planet is doomed. Several recent polls have revealed Americans’ growing skepticism. Solving global warming has become their lowest policy priority, according to a new Pew survey.

Moreover, strategies to reduce carbon have failed. Meeting in Rio de Janeiro in 1992, politicians from wealthy countries promised to cut emissions by 2000, but did no such thing. In Kyoto in 1997, leaders promised even stricter reductions by 2010, yet emissions have kept increasing unabated. Still, the leaders plan to meet in Copenhagen this December to agree to even more of the same — drastic reductions in emissions that no one will live up to. Another decade will be wasted.

Fortunately, there is a better option: to make low-carbon alternatives like solar and wind energy competitive with old carbon sources. This requires much more spending on research and development of low-carbon energy technology. We might have assumed that investment in this research would have increased when the Kyoto Protocol made fossil fuel use more expensive, but it has not.

Economic estimates that assign value to the long-term benefits that would come from reducing warming — things like fewer deaths from heat and less flooding — show that every dollar invested in quickly making low-carbon energy cheaper can do $16 worth of good. If the Kyoto agreement were fully obeyed through 2099, it would cut temperatures by only 0.3 degrees Fahrenheit. Each dollar would do only about 30 cents worth of good.

The Copenhagen agreement should instead call for every country to spend one-twentieth of a percent of its gross domestic product on low-carbon energy research and development. That would increase the amount of such spending 15-fold to $30 billion, yet the total cost would be only a sixth of the estimated $180 billion worth of lost growth that would result from the Kyoto restrictions.

Kyoto-style emissions cuts can only ever be an expensive distraction from the real business of weaning ourselves off fossil fuels. The fact is, carbon remains the only way for developing countries to work their way out of poverty. Coal burning provides half of the world’s electricity, and fully 80 percent of it in China and India, where laborers now enjoy a quality of life that their parents could barely imagine.

No green energy source is inexpensive enough to replace coal now. Given substantially more research, however, green energy could be cheaper than fossil fuels by mid-century.

Sadly, the old-style agreement planned for Copenhagen this December will have a negligible effect on temperatures. This renders meaningless any declarations of “success” that might be made after the conference. We must challenge the orthodoxy of Kyoto and create a smarter, more realistic strategy.

EL ESPECTADOR 30 Ago 2008 - 1:05 am Leche cruda (con panela)Por: Héctor Abad FaciolinceESTOY EN LÍOS CON LA LEY. SOY UN consumidor y un vendedor de leche sin pasteurizar. Tengo tres vacas Blanco Orejinegras y los fines de semana las ordeñamos para hacer quesito, arequipe, y tener leche fresca. Como soy mal ordeñador (les saco si mucho un vaso) Egidio hace la tarea, y si estamos de buenas les logra sacar 20 litros a las tres. Ya se sabe, las Blanco Orejinegro no son Holstein, pero a la vista me gustan más y no se les pegan casi las garrapatas ni las mata la aftosa. A la leche recién ordeñada, y puesta en vasos, le decimos “postrera” desde los tiempos de mi bisabuela, quizá porque es la leche que sirve para acompañar el postre. En realidad estas postreras —con una crema exquisita que sube a la superficie— sirven también para echarle al café y además para acompañar el arequipe, la mazamorra y sobre todo la panela.Y ahí vuelvo a estar en líos con la ley. Resulta que yo la panela no la compro en Carrefour, de productores industriales, sino que se la encargo a Adán, un campesino de Sonsón, que tiene un trapiche artesanal bajando dos horas a lomo de mula desde el pueblo, camino del río Arma. La panela que hace Adán no se puede comparar con la que venden en El Ley. Tiene un aroma, una consistencia, un sabor, que son únicos. Pero producir panela artesanal también se está convirtiendo en un delito en este país gobernado por patriotas que persiguen a los campesinos más pobres con leyes absurdas.Decía que también vendo leche cruda. Lo debo hacer porque la cantidad no es suficiente para que pase una empresa a recogerla. Además la finca queda a media hora a caballo de la carretera principal. Y si en semana no se ordeñan las vacas, pues se me pierden, porque les da mastitis. Como la leche sobra, se la vendemos barata a los vecinos, mucho más barata que la de Colanta o Parmalat. Los vecinos no se han enfermado nunca por la leche nuestra. Las vacas son sanas y están vacunadas, Egidio se lava las manos antes de ordeñar, lava las ubres con una solución yodada, y les tira a las ánimas benditas del Purgatorio los primeros chorros del ordeño de cada teta. Más higiene no ha sido necesaria por allá.De la panela puedo decir lo mismo. Aunque el Invima le haya exigido a Adán que monte un trapiche de acero inoxidable que él no se puede permitir, y que se ponga un bozal como el que él le pone de día al perro bravo, la panela que vende hierve tanto tiempo a tanta temperatura, que no hay bacteria ni bicho que resista ese fuego. La manía de la asepsia histérica es una ridiculez, o más bien, una exigencia interesada de los grandes productores de panela para acabar con los paneleros artesanales, como Adán.Es muy conocida la frase del general De Gaulle, que alguna vez se lamentó de lo difícil que era gobernar un país que producía 365 variedades de queso. Y se quedó corto, pues se calcula que en Francia se producen más de 500 tipos distintos de quesos artesanales, los cuales son una de las mayores riquezas de la gastronomía mundial. Estos deliciosos quesos artesanales se hacen con leche fresca (como la que quieren prohibir aquí).En el país de Pasteur buena parte de la leche no se pasteuriza. Si la pasteurizaran, acabarían con una de las mayores riquezas culturales de Francia. Se sabe que los buenos quesos franceses solamente se pueden producir con leche viva, con leche que fermenta por sí misma, es decir con lo que allá se llama lait cru o leche cruda. Hace unos años las grandes compañías productoras de alimentos se empeñaron, amparadas por una supuesta necesidad higiénica, en que todos los quesos de Francia se hicieran de manera industrial, mecanizada, aséptica. Estuvieron a punto de convertir a Francia en un supermercado gringo, en el que todos los quesos saben igual y a nadie le da diarrea jamás, pero engordan como cerdos. Por suerte para el queso artesanal francés, y para el paladar del mundo entero, los industriales no pudieron imponer este empobrecimiento cultural.Aquí, en lo pequeño, nos quieren también quitar lo poco que tenemos. Señor Presidente, señor Ministro de Protección Social: el gran problema de higiene de este país es el agua potable, los acueductos. No pierdan el tiempo y los recursos en perseguir a los vendedores de leche cruda y a los productores de panela artesanal. No persigan a los campesinos más pobres para favorecer a la industria de los alimentos. Sean patriotas de verdad, protejan a los más débiles en vez de perseguirlos con tonterías que no dicta la higiene, sino el interés.Héctor Abad Faciolince

Contaminación del Aire y Salud

Para los interesados en el tema, comunicado del día de hoy por parte del Ministerio del Ambiente japonés.

Results of FY2005 Environmental Health Surveillance concerning Air Pollution

October 31, 2007

In line with past surveillance findings, the result of FY2005 Environmental Health Surveillance concerning Air Pollution targeted at 3 and 6 year old children did not conclusively prove that an area with high concentration of air pollutants has high rate of respiratory symptoms. Also, there was no relationship recognized between the changes in the prevalence rate of asthma and changes in concentration of air pollutants.

Bueno, si hay público, podemos hablar del tema.

Buen día,

La Dificultad de las Metáforas en los Temas Ambientales (1)

En una reciente rueda de prensa, el encargado del Ministerio de Relaciones Exteriores de Japón, para responder a la pregunta de un periodista sobre las opciones reales que tiene el país en reducción de emisiones, el representante aseguró que eran muchas las cosas por hacer, basados en su poder tecnológico, a saber: 1) Reducir emisiones - bueno, parece que no sobraba repetirlo - y 2) "intentar y dar vapor al motor del crecimiento de la economía mundial." Digamos que en la incertidumbre del origen del vapor - y del funcionamiento del motor - empata.
