Exploring the complexities of cannabis farming in rural areas

Land use change in agricultural frontiers can have far-reaching social and environmental implications, such as habitat loss, water contamination, or worker demographic shifts — particularly when it involves the rapid expansion of a new industry such as cannabis production. A recent study published in Landscape and Urban Planning offers an interdisciplinary perspective on the drivers of cannabis production in rural areas, using interviews with farmers and spatial modeling to uncover key factors.

Led by researchers from UC Berkeley's Department of Environmental Science, Policy, and Management (ESPM) and the Cannabis Research Center, the article “Where money grows on trees: a socio-ecological assessment of land use change in an agricultural frontier” provides a social-ecological systems approach for assessing drivers of cannabis production in Southern Oregon, using interviews with farmers and spatial modeling to uncover key factors.

"Unlike other crops, we have less understanding of where and how cannabis is grown, making it an important area of ongoing research," said Van Butsic, a professor of cooperative extension in ESPM and the senior author of the study.

The researchers interviewed 14 cannabis farmers to identify major themes around their relationships with land use, and used those themes to generate predictors for models of land use change. Most of the interview-derived drivers were significantly associated with cannabis distribution and development, including parcel size, human footprint, distance to the nearest cannabis farm, the density of local cannabis production, clearable land cover, farm zoning, elevation, roughness, and distance to rivers. The interview data also provided insights into the relationship of cannabis with social and environmental dynamics.

“We gained many insights from the interview data,” said lead author and ESPM postdoctoral scholar Phoebe Parker-Shames. “For example, we knew from previous research that cannabis development tends to be clustered, but we understand a little better now that this is related to the ways in which cannabis farmers rely on each other to share knowledge, labor, and navigate uncertainty during difficult policy changes.”

One of the major themes that emerged from the interview data was the environmental stewardship values of the farmers. “There is a large untapped potential for education and management outreach to target farmers who got into this industry in part because of their ability to connect with the land,” Parker-Shames said. “The farmers we spoke to had a genuine desire to learn best practices in an industry without a lot of formal standards for production. I'm grateful that they were willing to share their experiences and insights with us.”

Additional Berkeley co-authors include ESPM professor Justin Brashares and alumni Hekia Bodwitch (PhD '17 ESPM). The study's findings provide valuable insights into the drivers of cannabis production and the environmental stewardship values of cannabis farmers, which can inform environmental policy, regulation, and best practices for sustainable cannabis production.

Reducing wildfire risk includes building communities to coexist with fire

The Camp Fire that destroyed the town of Paradise and other wildfires that have devastated communities in recent years have convinced wildfire experts that Californians need to take more than one approach to coexist with fire.

To better protect new houses against wildfire, California has building codes, but where residential communities are built on the landscape and how they are designed are also very important to limit wildfire-related losses, according to University of California Cooperative Extension specialists Max Moritz and Van Butsic. 

“Defensible space and vegetation management is important, but in the long term, where and how we build new developments will be equally important for keeping Californians safe,” said Butsic, who studies land use.

To develop their recommendations for reducing wildfire risk for future community development, Moritz, who specializes in wildfire, and Butsic reviewed fire studies and consulted firefighters and community planners.

To build on fire-prone landscapes, we need better guidance on where and how to safely build our communities.

Their new publication, “Building to Coexist with Fire: Risk Reduction Measures for New Development,” is designed for city planners, fire districts and communities to incorporate community-scale risk reduction measures when building or rebuilding in fire-prone areas.

“There is currently little codified guidance for where and how to build our communities in California, aside from building codes for individual structures and a few requirements for road access and water supplies,” said Moritz, who is based at UC Santa Barbara.

Wildfire consultant and architect David Shew, who retired as a CAL FIRE chief after 31 years, said, “I can state without hesitation that the land use planning principles and design recommendations identified in this study are necessary steps to help increase wildfire resiliency to existing and future communities.  Being a first-hand witness to the increasingly destructive nature of wildfires, I can attest to the value and necessity for these improvements to be integrated into our built environment.  This should become a much-used reference for every planning and fire official who face wildfire impacts.”

Clustering homes is safer because the agricultural land (shown as striped rows) provides a protective buffer. This pattern of development also is easier to defend from fire and requires fewer fire suppression resources. Source: Fire Mitigation in the Wildland Urban Interface

To reduce fire vulnerability of communities, Moritz and coauthor Butsic, who is based at UC Berkeley, recommend including fire professionals and biological resource experts early in the community planning process. They also recommend considering the placement of communities on the landscape, such as near bodies of water and agricultural land, and how they are laid out to minimize exposure to wildfire. Key considerations include defensibility, risk of ignition and ease of evacuating residents.

“This report provides both a robust justification for integrating resilience practices into land use planning and community design, and a toolbox for doing so,” Sarah G.Newkirk, director of disaster resilience with The Nature Conservancy in California. “The risk reduction measures described can be put to use immediately – ideally in combination with each other – both in ongoing wildfire recovery planning, and in local hazard mitigation planning. Furthermore, the report should be a wake-up call to FEMA to think broadly about how best to support wildfire mitigation in California.”

To more efficiently reduce fuel in new communities, Moritz and Butsic write, “The design, maintenance and use of defensible space for fire protection is easier when neighborhoods are developed more densely and are built to stringent fire-resistant building codes.”

Development near slopes should be set back far enough from the slope’s edge to provide safety from flames moving up the slope or lapping over the edge. The safety area depends on the height of buildings and potential flame lengths of burning vegetation on the slope.

In the 31-page publication, they present risk reduction measures for four design contexts:

  • landscape setting – engage in strategic planning much earlier, use hazard maps and use major landscape features
  • separation from wildfire source—use nonflammable amenities in design, employ safe setbacks on slopes and concentrate on inner side of roadways
  • density management – cluster with other homes
  • protective infrastructure – harden public facilities and refuges, locate power lines underground and augment water requirements.

They provide examples for each risk reduction measure, along with some discussion of challenges associated with each measure.

“Our hope is that this guidance will be helpful for agency personnel involved in evaluating and approving future development in California,” Moritz said. “Because there is a pressing need for additional housing in California, communities must be built with design principles that make them safer to inhabit and less vulnerable to inevitable wildfires.”

Cannabis growers asked to comment on permit process

“The majority of cannabis farmers are not joining the legal market and we want to know why,” said Van Butsic, UC Cooperative Extension specialist.

California has legalized marijuana, but commercial cannabis growers have been slow to obtain the required state and local permits. To find out what deters them from complying with new laws, University of California scientists are asking cannabis growers to participate in a survey about their experiences with the regulated market.

“The majority of cannabis farmers are not joining the legal market and we want to know why,” said Van Butsic, UC Cooperative Extension specialist in the Department of Environmental Science, Policy & Management at UC Berkeley. “The objective is to identify barriers to joining the legal market.”

The researchers plan to share the results with policymakers as well as with the cannabis farming community and other researchers.

“Cannabis growers will have an opportunity to tell us what's wrong with the regulatory system so we can advise policymakers on changes they could make to improve compliance,” Butsic said.

Butsic estimates that less than one-third of cannabis growers in Humboldt County have completed the permit process. He says it's difficult to estimate statewide how many cannabis growers are operating illegally because laws vary from county to county and in many parts of the state, local governments don't allow cannabis growing.

Cannabis grows in Siskiyou County as seen from Google Earth. Research has shown that illegal cannabis production causes environmental damage.

One impact from cannabis growers not joining the regulated market is the state receives lower revenues from cultivation taxes.

Beginning on Jan. 1, 2018, two taxes went into effect: a cultivation tax on harvested cannabis that enters the commercial market and a 15% excise tax on purchases of cannabis and cannabis products.

Prop. 64, approved by voters in 2016, stated: “The revenues will provide funds to invest in public health programs that educate youth to prevent and treat serious substance abuse, train local law enforcement to enforce the new law with a focus on DUI enforcement, invest in communities to reduce the illicit market and create job opportunities, and provide for environmental cleanup and restoration of public lands damaged by illegal marijuana cultivation.”

Legalization was projected to create $1 billion annually in new state revenue, but initial tax revenue has been significantly lower. In the Governor's May 1 budget revision, cannabis cultivation and cannabis retail salesrevenues were projected at $288 million in 2018-19 and $359 million in 2019-20.

Compliance is important not only for tax revenue, but also for the environment, Butsic said. Research has shown that illegal cannabis production causes environmental damage, including rodenticide poisoning of forest wildlife.

“We know there are environmental impacts from non-permitted farms,” Butsic said. “The more growers are able to comply, the better off our environment will be.”

The survey can be anonymously filled out online at https://ucanr.edu/sites/compliance until Aug. 1. Cannabis growers who wish to provide more information can volunteer to give the researchers an interview.

CalLands maps cropland ownership across California

Two UCANR Cooperative Extension specialists have recently launched CalLands, a powerful online tool that can help users understand how land ownership impacts California's croplands.

To build the CalLands' interactive website, Luke Macaulay and Van Butsic — both assistant UC Cooperative Extension specialists based in UC Berkeley's Department of Environmental Science, Policy, and Management — combined satellite-generated maps of land cover created by the U.S. Department of Agriculture with publicly available land ownership records. Next, they anonymized ownership identity and pulled data from all 58 California counties to include parcels of land larger than five acres. The result is a database that features 543,495 privately-owned properties across the state, creating a data-rich map of crops and ownership boundary lines in every county. The interactive map can be filtered by county to display characteristics of land ownership, percentages of private and public ownership, breakdowns by crop-type, and summaries of land-use statistics.

CalLands allows users to explore how crops are distributed within a county or across the state or understand how ownership size impacts how land is used. In a 2017 study on cropland ownership published in California Agriculture, Butsic and Macaulay discovered that the largest five percent of properties account for 50 percent of California cropland. The two created CalLands with the aim of helping a wide variety of stakeholders understand land cover and land use at the county and individual land ownership scale.

“CalLands helps expand people's understanding of the landscape and how farmers across the state are using their land,” Macaulay says.

The website tells the story in visual terms of the location of key crops over time, including water-intensive plants like alfalfa and almonds, and illustrates the locations and acreages of both annual and perennial crops. This information may be useful for those seeking to understand agricultural water use and expansion and change of crops over time. The team hopes that the tool will also help scientists conduct research that is beneficial to many agricultural stakeholders, such as UC Cooperative Extension specialists creating outreach programming, county officials proposing regulations, and resource managers hoping to understand cropland production.

Currently, CalLands features cropland data from 2013-2017, allowing users to toggle between these annual datasets. Macaulay and Butsic plan for future versions of CalLands to include the capability of producing graphs to help users understand how crop planting changes over time as farming shifts and land changes hands. “We look forward to adding more features to CalLands,” Butsic said. “We want to implement changes on the site based on what Californians need.”
