Using floods to replenish groundwater


M.Cubed produced four reports for Sustainable Conservation on using floodwaters to recharge aquifers in California’s Central Valley. The first is on expected costs. The next three are a set on the benefits, participation incentives and financing options for using floodwaters in wetter years to replenish groundwater aquifers. We found that costs would range around $100 per acre-foot, and beneficiaries include not only local farmers, but also downstream communities with lower flood control costs, upstream water users with more space for storage instead of flood control, increased hydropower generation, and more streamside habitat. We discussed several different approaches to incentives based on our experience in a range of market-based regulatory settings and the water transfer market.

With the PPIC’s release of Water and the Future of the San Joaquin Valley, which forecasts a loss of 500,000 acres of agricultural production due to reduced groundwater pumping under the State Groundwater Management Act (SGMA), local solutions that mitigate groundwater restrictions should be moving to the fore.

Don Cameron at Terranova Ranch started doing this deliberately earlier this decade, and working with Phil Bachand and UC Davis, more study has shown the effectiveness, and the lack of risk to crops, from this strategy. The Department of Water Resources has implemented the Flood-MAR program to explore this alternative further. The Flood-MAR whitepaper explores many of these issues, but its list of beneficiaries is incomplete, and the program appears to not yet moved on to how to effectively implement these programs integrated with the local SGMA plans. Our white papers could be useful starting points for that discussion.

Reverse auctions for storage gaining favor


Two recent reports highlight the benefits of using “reverse auctions”. In a reverse auction, the buyer specifies a quantity to be purchased, and sellers bid to provide a portion of that quantity.  An article in Utility Dive summarizes some of the experiences with renewable market auctions.  A separate report in the Review of Environmental Economics and Policy goes further to lay out five guidelines:

  1. Encourage a Large Number of Auction Participants
  2. Limit the Amount of Auctioned Capacity
  3. Leverage Policy Frameworks and Market Structures
  4. Earmark a Portion of Auctioned Capacity for Less-mature Technologies
  5. Balance Penalizing Delivery Failures and Fostering Competition

This policy prescription requires well-informed policy makers balancing different factors–not a task that is well suited to a state legislature. How to develop such a coherent policy can done in two ways. The first is to let the a state commission work through a proceeding to set an overall target and structure. But perhaps a more fruitful approach would be to let local utilities, such as California’s community choice aggregators (CCAs) to set up individual auctions, maybe even setting their own storage targets and then experimenting with different approaches.

California has repeatedly made errors by overly relying on centralized market structures that overcommit or mismatch resource acquisition. This arises because a mistake by a single central buyer is multiplied across all load while a mistake by one buyer within a decentralized market is largely isolated to the load of that one buyer. Without perfect foresight and a distinct lack of mechanisms to appropriately share risk between buyers and sellers, we should be designing an electricity market that mitigates risks to consumers rather than trying to achieve a mythological “optimal” result.

Misunderstanding the Green New Deal


The media and the public appears to have confused the Green Party’s platform calling for 100% renewable energy by 2030 with the goals in the Joint Resolution for a Green New Deal introduced by Senator Edward Markey (D-MA) and Representative Alexandria Ocasio-Cortez (D-NY). The Joint Resolution calls for a “10-year national mobilization,” but contains no deadlines other than zero greenhouse-gas emissions by 2050, which is 30+ years from now. Given that we went from horse and buggies and wood stoves to widespread automobile use and electrification in 30 years at the beginning of the twentieth century, such a transformation doesn’t seem imposing.

Soda tax really works in Berkeley


A just released study on the effects of the Berkeley, California soda tax of one cent per ounce found that soda consumption has fallen 52% over the last four years. That is a remarkable price elasticity. Assuming a 20-ounce bottle costs $1.99, with a tax of 20 cents, that implies a price elasticity of -5. In other words, for every 1% o price increase, demand falls 5%. The study relied on household surveys, which are not always reliable about consumption quantities, so it would be interesting to see actual sales data.

Willingness Toupee


David M. McEvoyO. Ashton Morgan and John C. Whitehead

No 19-01, Working Papers from Department of Economics, Appalachian State University

Abstract: In this paper we tackle the hairy problem of male pattern baldness. We survey balding men and elicit their willingness to pay to move from their current sad situation to a more plentiful one. Then we comb-over the results. What’s the average willingness to pay to move from a glistening cue ball to a luscious mane? About $30,000.

Some sample footnotes:

  1. As is standard in the discipline, author order is determined by reverse Norwood Baldness Scale.
  2. The “stone piece” was a block of dark slate tied around the head to achieve the appearance of a full head of hair. While there are no sources of any such thing actually taking place, the authors imagine that it must have happened.
  3. “In ‘Simpson and Delilah,’ Homer attempts to pursue an executive position in which he doesn’t have a comparative advantage. Mr. Burns confuses Homer with a young go-getter and promotes him to an executive position after Homer has managed to scam himself some Dimoxinil–a miracle cure for baldness–and grow some hair.” (Carilli 2014, p. 11)
  4. It is important to note that the authors did not even bother looking for other studies.

7. Both of these models can be found in the NLogit manual (www.limdep.com) or via Google Scholar. They’re legit but we really don’t want to add any references besides the Simpsons book.

9.Referee #2 may try to claim that you cannot estimate WTP from a mixed logit model with a price parameter distribution that includes negative values because these respondents’ WTP will be undefined. Since distributions that constrain WTP to the positive realm do not perform as well statistically as the normal (we didn’t really check this) and (likely) generate goofy WTP estimates, we choose to present WTP estimated with the mean coefficients. The gullible, er, reasonable, reader will just go along with it since the MXL WTP number is so close to the ECLC WTP estimate and this lends reliability to our data.

Make “Sustainable Food” the Economic Engine of Downtown Davis



Many communities around the region, such as Sacramento and Woodland, have jumped on the “farm to fork” bandwagon to promote their relationships with agriculture. Davis can distinguish itself from the crowd by taking this a step further to promote itself as the center of “sustainable food.” In doing this, Davis can develop placemaking that is the key to economic development and vitality.

Davis is home to one of the top-rated food production research universities in the world in UC Davis. The City of Davis should leverage this position and strengthen its relationship to reinvigorate the downtown. The City has an opportunity as part of its Downtown Davis or Core Area Specific Plan to define a vision to achieve that goal.

Sustainable food minimizes damages to the planet in its cultivation, production, preparation, consumption and disposal. It is largely plant-based because this is the most direct way to deliver calories and protein to our diets. Animal production has much higher waste products, resource consumption, greenhouse gas emissions, and tainted food per calorie or gram of protein. For example, based on U.S. Department of Agriculture statistics, beef production emits four times as much greenhouse gases (GHGs) per calorie than soybeans or wheat and twice as much GHGs per gram of protein. Given California’s goal to be a “net carbon zero” emitter by 2045, the state will need to take a wide range of steps to cut emissions across the board, including in food production and consumption. Sustainable food is also more ethically consistent and healthful than our current food production and consumption patterns.

Sustainable food has been in the press frequently of late, with numerous stories in the Bay Area media. San Francisco has become the venture capital center of the world—especially for sustainable food–but real estate is becoming too expensive there to allow an industry that focuses on physical products sufficient space. Davis is close enough to that center for easy communication, but still has comparatively inexpensive land.

Creating a sustainable food ecology in Davis would have five aspects:

  1. Supporting innovation in sustainable food production and distribution
  2. Providing sustainable infrastructure to support companies that are innovating
  3. Serving and delivering sustainable food locally
  4. Preparing food that is consumed locally in a sustainable manner
  5. Attracting sustainable food-oriented tourism

The City can focus development of a sustainable food industry hub in the “Flex District” proposed for the G Street Corridor in the Downtown Plan. This area could house a wider range of facilities, such as test labs, within easy access distance of the UCD campus and the Capitol Corridor train to the Bay Area. Larger research facilities can be housed in other parts of the City where larger, industrial facilities are more appropriate.

Part of the attraction to companies locating here could be a sustainable infrastructure configuration starting in this district, with a district energy network and electric microgrid supporting fully electrified space conditioning and water heating systems. The other sustainability attributes identified in the Downtown Davis Plan should be incorporated and highlighted.

We can also encourage existing restaurants to serve more sustainable food on their menus, and attract new restaurants to cater to the new sustainable food businesses and their employees. The investors and workers at these companies are much more likely to follow their ethical beliefs in their consumption choices. The City could provide incentives through reduced fees to existing businesses, and evaluate how to speed the start up of new businesses.

As part of establishing a sustainable environment, the City should facilitate switching restaurants to more sustainable preparation practices. This includes switching from natural gas to induction cooktops and convection ovens, district water heating and space conditioning, and better management of waste. (Yes, we may need to recruit chefs for this new challenge.)

Finally, Davis can become a sustainable food destination. Less than 20% of our downtown visitors are from out of town according to analysis by consultants to City working on the Downtown Davis Plan. Given our location on the Capitol Corridor train route and Interstate 80, the community has much room for growth in tourism to boost our economy beyond UCD students’ parents visiting in September and June.

Davis already has a core attraction in its world-famous Farmers’ Market. With the addition of plant-based oriented restaurants and closer integration with the Mondavi Center entertainment area, a visitor could easily spend a whole day in Davis with a quick trip on the train from the Bay Area. Implementing this vision just needs closer coordination with UCD to bring events to Mondavi and the new Shrem Art Museum on Saturdays and setting up an electric bus shuttle between there and downtown.

UCD’s Robert Mondavi Institute for Wine and Food Sciences provides an example of how local development can be both sustainable and invigorating. That locale now has a microgrid that relies on renewable power. Both UCD and the City could benefit from a closer relationship centered around sustainable food in several dimensions.

Implementing all of this vision requires going beyond the form-based zoning codes that will come out of the Core Area Specific Plan. The City needs a comprehensive economic development plan, direction and resources for its economic development staff, and a willingness to focus on removing the barriers to bringing and supporting these businesses in Davis.

Another finding of the obvious from academics…


This study published in the American Journal of Agricultural Economics seems to have a surprising finding, at least to academic economists, that farmers with riskier water supplies rely less on irrigation! What? If you’re uncertain about whether you will get water every year, you are less likely to count on that water to irrigate your crops? Who possibly would think that way?
