hay de economistas a economistas...

En este caso, economistas agrícolas:



Dangerous academics?

I got my PhD at the Department of Agricultural and Resource Economics at UC Davis. I entered the department to do development economics but ended up specializing in environmental and natural resource economics (ERE).*

But that didn't mean that I ignored agricultural economics. In fact, I learned quite a bit about farmers (most of it good), agricultural policies, and land and water management.

OTOH, I also learned about the "consultant-research machine" that one can find in most academic settings. In short, academics with credibility are paid to write reports for people in industry. Usually these reports are objective and based on the researcher's beliefs, but sometimes money can push the border between objective and "whatever you want us to say." It's hard to know.

In one case, we (ERE grad students) were depressed to see several of our professors and fellow students working on the cost-benefit of pesticide use, publishing "findings" for academic, industry and regulatory audiences that supported of the use of methyl bromide (MBr) for strawberries [PDF].** It seems that they assisted in winning an exemption from international protocols to ban methyl bromide (a carcinogen and ozone-depleting chemical).

MBr was eventually phased out, but now I see that its replacement -- methyl iodide -- is considered dangerousfor farm workers, the environment (and perhaps consumers).

And guess who is writing in support of methyl iodide [PDF]? The same folks. This is a sad pattern.

Bottom Line: Academics should remember that costs on one group for benefits to another group involves politics, not just economics. And they need to be careful about taking money from winners to cast doubt on costs to losers.


* In one memorable rebellion, I presented evidence to the chair (an aggie) that 2/3rds of the professors were aggies, but 2/3rds of the graduate students were ERE-oriented. That fact was not well received.

** These folks also claimed to be environmental economists. We agreed that their work related to environmental issues; we were not sure that it supported a healthy environment.
Moraleja: Parece que no hay entre economistas cosa tal como la esfera pura y ascéptica de la academia con sus cubículos y sus torres de marfíl. Lo que sí hay es una elección (otra más!!)...

Ganancias por reducir la erosión

Estupendo mapa de EUA.

por qué hay una división en el meridiano100, marca de referencia en el desarrollo de la infraestructura hidrológica de EUA? Aquí mi pronóstico (no he revisado el paper)

  • al Este del meridiano las presas se utilizan para control de inundaciones, para suministro y para generar electricidad, sobre todo en el NE. Todos usos de altísimo valor. Por eso nueva inglaterra, por ejemplo, aparece con los colores más obscuros
  • los clusters oscuros en el Oeste o bien son distritos de riego, como en California central, desde la frontera, el Imperial Valley, hasta el delta del Sacramento y el San Joaquín, a la altura de SF, o sitios de mega proyectos, como la Hoover y la Glen Canyon en Colorado/Utah/Arizona
Moraleja: La espacialización de los problemas económico-ecológicos es tremenda!! Viva la multidisciplina!!
