Groundwater Management Resources from the USGS

The US Geological Survey is the nation’s premiere earth sciences agency. I’ve long been impressed with their work in the water domain, having relied on data collected at their stream gages for many projects over the years. As I’m getting more interested in the science and policies of groundwater management lately, here is a collection of groundwater resources from the USGS:

Great Kora Player (not) Coming to Ashkenaz in Berkeley

Update on May 3: Apparently the show at Ashkenaz has been cancelled. Not sure if other NorCal appearances are still on. -Matt

Madou Sidiki Diabaté, kora player from Mali, will be playing Ashkenaz on May 6. He is from an extraordinary music family, and the little brother of arguably the best kora player in the world, Toumani Diabaté. Watching this video, I can see that he not only some serious chops himself, but also an instrument of extraordinary (western?) craftsmanship:

The next week, Dusu Mali Band will be playing: “Ibrahim Kelly (nephew of Ali Farka Touré) combines his Malian roots with a Pan African fusion of jazz, blues, funk, and electric sound. Dusu Mali Band brings high energy, love, and conscious music to you.” Funky desert trance stuff:

Good couple of weeks for Malian music with a pedigree! For more great music, check the Bay Area African Music Calendar.

Creating Decision Support Systems with Excel

Our organization, the Pacific Institute, has traditionally researched and written reports on public policy and environmental issues. In recent years, we’ve gotten more involved in creating tools for others to use to help them make better management decisions. This type of software sometimes falls under the heading of “decision support systems” or “expert systems”.

One of the first Excel-based programs the Institute created (before I joined the staff) was the Water-to-Air Model which helps water utilities to understand how their operations contribute to air pollution, and how  water conservation can reduce pollution and bring about air quality improvements. I gained a lot of experience with creating Excel-based models in grad school at Tufts. For my MS Thesis, among other things, I created an Excel-based hydrologic and water quality model for predicting bacteria concentrations in lakes and rivers (download the zipped .xls file here).

The model was created in Microsoft Excel, which is a decent platform for this type of software. It’s ubiquitous: almost everyone in industry or government has a copy. Users know the interface: they already know what the menus and buttons do, and don’t have to learn a whole new set of conventions. It overs certain advantages to the programmer as well. You can use Excel’s built-in capabilities rather than creating routines for data entry, financial analysis, charting, etc.

Excel is not perfect for these applications. Recently, I’ve become more and more convinced that the best way to deliver this kind of software is via the web. Spreadsheets are hard to share and can usually only be used by one person at a time. It’s hard to make updates and push new versions out to users. It’s also hard to collect information about who is using your software and how they are using it.Lastly, Excel is not free, and not everyone has it, especially in poor countries. The web can overcome many of these obstacles, which is one reason we’re moving increasingly in that direction, for example with the forthcoming Household Water-Energy Calculator or the prototype Community Choices Water and Sanitation Decision Support System.

Still, I think that Excel will continue to be used for these kinds of applications for many years to come. It will continue to be of use for prototyping and what some developers call rapid application development. Here are some links and resources I’ve collected for creating Excel-based decision support systems:

Chevron’s Sneaky Push Poll in Richmond, California

Chevron looms large over the city of Richmond, both literally and figuratively. Hundreds of acres of the city’s hilltops and waterfront are occupied by the Bay Area’s largest refinery. You might think that being home to the refinery, the Bay Area’s worst polluter, would have an upside in terms of jobs and tax revenues. But you’d be dead wrong. For years, Chevron has resisted every effort by the city to collect more tax revenues from the world’s second-most profitable corporation. This isn’t really news. Last month, Forbes reported that the 25 biggest companies pay less in taxes than most citizens.

Chevron's Richmond Refiner

This afternoon, I got a phone call from a pollster (first ever on my mobile) saying that he was polling Richmond voters, and that the information “would be used for research.” When I asked who was paying for the survey, he conceded, “I believe it’s Chevron.” I agreed to continue, because I thought it might be a chance to let the company brass know where I stand: i.e. that they should stop trying to weasel out of justly compensating the city, re-focus their efforts on pollution control, and abandon the folly of the plant expansion to process dirty tar sands from Canada.

As the poll got started, I was asked how favorably I viewed various entities, including some of our local utilities: PG&E, EBMUD, Chevron, Mayor Gayle McLaughlin, Richmond City Council, etc. Then he caller asked about some ballot measures having to do with utility taxes: “Would I support a measure to cap natural gas taxes on the largest customers at $20 million, and provide all sorts of breaks on seniors and low-income families, etc.” Hmm… lower taxes on little old ladies, who could argue with that? I almost forgot about the large customer thing. How many “large customers” are there in the city. One. And it turns out they’ve been under-paying for years.

When the caller said, “Let me read you some more information about the ballot measure, and then ask your opinion,” I realized that this was a push poll, and they were trying to manipulate and misinform me.

This is nothing new. If you read back on the history of Richmond’s history of trying to collect more taxes from Chevron, you’ll find a history of deliberate obfuscation. According to this wikipedia article, Chevron responded to a 2006  ballot initiative to raise taxes on the refinery with “a massive flyer campaign, suggesting it would lead to evictions of seniors and closing of small businesses.” Since moving to Richmond, I have gotten a handful of glossy, colorful brochures in the mail explaining how committed Chevron is to the community. How much do they really contribute? According to the research brief, “Richmond’s Tax Revenue from Chevron” written by my colleague Eli Moore at the Pacific Institute:

Like many large corporations, Chevron contributes to the community not only through taxes and fees, but also through charitable donations. Chevron reported giving $1.25 million in charitable donations to service providers in Richmond and Contra Costa County during 20062 and $1.02 million in 2007.3 During this two-year period when the company’s charitable donations averaged $1.1 million, it took action to reduce its annual contributions to city revenue by an estimated $9.4 million.4 This shows Chevron’s charitable donations are minimal when compared with how much tax, and ultimately public revenue, Chevron has withdrawn and continues to work to evade.

My message to Chevron: these tactics are sneaky, disingenuous, and unethical. The issue of taxes to a large multi-national corporation are totally unrelated to taxes on residents. Stop trying to muddy the waters and confuse voters. Instead of spending money to manipulate and misinform the public, step up and do what’s right.

As a prologue to this incident, I called the mayor’s office to ask if they were aware of the poll and if Mayor McLaughlin had plans to issue a statement, and I was told that they had already received a number of complaints about the polls, but that it wasn’t clear what response there would be, if any.

I also called the refinery, and the operator said, “Oh, you mean the poll from the city?” before transferring me to public affairs’ voice mail. Is Chevron deliberately trying to trick people into believing that the poll is being conducted by the city?

Free Concerts in San Francisco’s Stern Grove this Summer

Just announced! The 73rd annual Stern Grove Festival in San Francisco. Free concerts every Sunday at 2:00 pm from June 20 through August 22, 2010. There are, as always, some incredible artists.

Angelique Kidjo, the dynamic songstress from Benin, kicks things off on June 20. (For more African concerts, check the San Francisco Bay Area African Music Calendar. And if you have any shows to add to the calendar, please email me!)

Another band I’m excited about is Caravan Palace. Seductive blend of swing, gypsy jazz, and electronica.

Here’s my advice if you go: get there early, bring a blanket, a thermos of coffee, and the Sunday paper.
