The tragedy of the commons in Los Angeles, California.
After watching a YouTube video where the mystic Sadhguru shared his perspective on California’s wildfire, I found some truth in his argument. Given his humanitarian efforts in environmental initiatives like the Save Soil movement, he likely has a solid understanding of nature to some extent.
In previous posts, I’ve explored the LA wildfires — analyzing their causes, proposing solutions, and discussing the broader issue of the tragedy of the commons, which still remains relevant. However, I realize I haven’t delved deeply enough into the ecological factors unique to California.
Sadhguru claims that the severity of California’s wildfires is largely due to excessive groundwater extraction. He argues that deep tube wells have drained the water table beyond the reach of tree roots, leaving vegetation extremely dry and highly flammable. According to him, if trees had more water content in their sap, they would be more resistant to fire. While he acknowledges that fire is a natural part of California’s ecosystem, he believes human overuse of water has disrupted this balance, making wildfires far more destructive than they would be naturally.
Sadhguru contrasts California’s wildfire-prone environment with Tennessee, where he suggests that setting fire to the forest would be much more difficult, even if given gasoline. His reasoning is that Tennessee’s land is more water-rich, meaning its trees and vegetation contain more moisture, making them naturally more resistant to fire.
In contrast, he argues that California’s excessive groundwater extraction has left its vegetation dry and combustible, turning entire forests into what he describes as “matchsticks.” His broader implication is that ecosystems with sufficient water can better withstand fire, whereas California’s landscape has become unnaturally vulnerable due to human intervention.
Since I’m not an expert in this field, I decided to share this perspective with ChatGPT to gain insights and a deeper understanding. I’m aware that California has maintained a sophisticated groundwater system for decades, particularly from my research on economist Elinor Ostrom, who won a Nobel Prize for challenging the tragedy of the commons — an idea closely tied to Los Angeles water resource management.
Elinor Ostrom on water management and creating #institutions
Elinor Ostrom describes how early 20th-century groundwater pumpers in the Los Angeles area engaged in a “pumping race,” extracting as much water as was individually profitable while ignoring the collective consequences. However, by the 1940s and 1950s, these same pumpers invested in institutional solutions to manage the commons effectively. They established private associations, funded legal battles to allocate water rights, drafted and passed legislation, and created special districts to tax water withdrawals and property usage.
Despite this success, similar efforts in the Mojave Water Agency area failed, demonstrating that self-governance is not always guaranteed to succeed. Ostrom argues that successful cooperation depends on shared understandings of the problem, the ability to break down complex issues into manageable parts, and the recognition of diverse interests. Without these, even well-designed institutional structures may fail.

Me: [Fed the YouTube video transcript to ChatGPT 4o].
ChatGPT:
<contemplator> Alright, let’s break this down carefully. Sadhguru is making an ecological and hydrological argument about the role of water retention in trees and its impact on wildfires. His claim, in essence, is that widespread groundwater depletion leads to drier vegetation, which in turn makes forests and other landscapes more combustible, contributing to the severity of wildfires. This requires careful examination on multiple levels.
1. Understanding the Core Claim: Water Content and Fire Resistance
Sadhguru is drawing a parallel between two different environments: Tennessee, where he suggests it would be difficult to start a wildfire, and California, where wildfires are rampant. His reasoning is that in California, the land has been over-extracted of groundwater, leaving vegetation drier and highly flammable. He makes the following key assertions:
- Trees and plants in a healthier, more hydrated landscape contain more moisture, which helps them resist catching fire.
- California’s ecosystem, due to excessive groundwater extraction via deep tube wells, has become unnaturally dry.
- Because the land is parched and vegetation lacks sufficient water content, fires spread more rapidly and intensely.
- Historically, natural cycles of fire and rain regulated these ecosystems, but human intervention has altered this balance.
2. How Valid is This Claim?
Let’s question every step of this reasoning.
a) Is It True That Moisture in Trees Prevents Wildfires?
Yes, moisture content in vegetation plays a critical role in fire resistance. This is a well-documented principle in wildfire science. Green, hydrated plants resist burning more effectively than dry, desiccated ones. In fact, fire risk assessments include “fuel moisture content” as a key variable, measuring how much water is present in vegetation. High moisture slows down combustion, while dry plants ignite more easily.
Supporting evidence:
- Live trees and plants with high water content require much more heat energy to ignite than dead or dry ones.
- Firefighters often try to increase moisture levels in forests through controlled watering or creating “wet barriers” to slow fires.
Counterpoints:
- Some plants, like eucalyptus, are naturally fire-prone despite their sap content due to high oil concentrations.
- Many forests, including those in wetter regions, experience wildfires. So, moisture alone isn’t the only factor.
b) Has Groundwater Depletion Made California’s Trees More Combustible?
Sadhguru argues that deep tube wells are extracting water beyond the reach of tree roots, leading to a drier landscape. This is plausible but requires scrutiny.
- Supporting evidence:
- California has a long history of over-extracting groundwater, particularly in agricultural regions.
- A 2014 NASA study confirmed significant groundwater depletion in the Central Valley.
- When trees experience drought stress, they lose their ability to retain moisture, making them more vulnerable to fire.
Counterpoints:
- Wildfire severity is influenced by multiple factors, not just water extraction. Other key drivers include rising temperatures, increased winds, and historical fire suppression leading to excessive fuel buildup.
- Some of California’s wildfires occur in areas that don’t rely heavily on groundwater extraction, such as mountainous regions.
c) Is the Fire Cycle in California Entirely Human-Induced?
Sadhguru acknowledges that California has natural fire cycles but claims that current wildfires are excessive due to human interference. This is partly true but oversimplifies the situation.
- Supporting evidence:
- Fire ecologists agree that California has natural fire-adapted ecosystems that evolved to burn periodically.
- However, human activities (urban expansion, fire suppression policies, and climate change) have made fires worse.
Counterpoints:
- Even before large-scale human settlement, California experienced megafires. Native American fire practices included controlled burns to manage forests.
- Many wildfires today are ignited by electrical infrastructure (e.g., PG&E power line failures), not just dry vegetation.
3. Examining His Broader Implication: Overpopulation and Sustainability
Sadhguru’s final point is more philosophical — he argues that there are “too many” people extracting resources unsustainably. While this taps into Malthusian concerns about overpopulation, it needs a nuanced perspective.
- Supporting evidence:
- Population growth has increased resource demand, leading to greater land use and water extraction.
- Urban expansion into fire-prone areas (wildland-urban interface) has heightened the risks of catastrophic wildfires.
Counterpoints:
- Technological and policy solutions (e.g., sustainable land management, water conservation) can mitigate these problems without necessarily reducing population size.
- Many regions with high population density do not experience wildfires, so overpopulation alone is not the sole issue.
Final Analysis
Sadhguru’s argument contains elements of truth, particularly regarding the relationship between moisture content in vegetation and fire susceptibility. However, his explanation simplifies a complex issue. Wildfire severity is driven by multiple factors, including climate change, fire suppression policies, and land management practices. While groundwater depletion is certainly a contributing factor, it is not the sole reason for California’s wildfires.
His ecological intuition is sound, but it must be contextualized within a broader scientific framework. </contemplator>
Me: Yeah, the one flaw I thought in his view was how long ago wildfires were present in California. As you mentioned: Even before large-scale human settlement, California experienced megafires. Native American fire practices included controlled burns to manage forests. Can you tell me how long ago exactly did California experience wildfires? And more about them, was it as severe as today? How was it handled? Who documented them?
ChatGPT:
<contemplator> Reflecting on the history of wildfires in California, it’s evident that these events have been an integral part of the state’s ecological narrative for millennia. Long before European settlers arrived, Indigenous tribes practiced controlled burns, a methodical use of fire to manage and rejuvenate the land. This practice not only reduced the risk of uncontrolled wildfires but also promoted biodiversity and maintained the health of various ecosystems. The National Park Service notes that Indigenous nations have used fire for thousands of years as a tool to steward the land, and still do today. :contentReference[oaicite:0]{index=0}
However, with the advent of European colonization, perceptions of fire shifted dramatically. Early settlers, unfamiliar with the ecological benefits of controlled burns, viewed these intentional fires as hazardous and primitive. This misunderstanding led to the suppression of Indigenous fire practices. In 1850, California enacted the Act for the Government and Protection of Indians, which, despite its title, included provisions that outlawed intentional burning. This legislation effectively criminalized the traditional fire stewardship of Native tribes.
The suppression of controlled burns had profound ecological consequences. Without regular, low-intensity fires to clear underbrush and manage vegetation, forests became denser, and the accumulation of dry fuel increased. This set the stage for larger, more destructive wildfires. Historical records, such as those from the late 19th century, document significant fires like the Santiago Canyon Fire of 1889, which consumed over 300,000 acres in Southern California.
Comparing past wildfires to those of today reveals both similarities and differences. While large fires have always been part of California’s landscape, the frequency and intensity of these events have escalated in recent decades. Factors such as climate change, prolonged droughts, and continued fire suppression policies have contributed to this increase. Data indicates that 15 of the 20 largest fires in California’s recorded history have occurred since 2000.
In response to the growing wildfire crisis, there has been a renewed interest in Indigenous fire management practices. Recognizing the effectiveness of controlled burns, California has begun to collaborate with Native tribes to reintroduce these traditional methods. This partnership aims to reduce the risk of catastrophic wildfires and restore ecological balance.
In summary, wildfires have been a natural and necessary component of California’s ecosystems for thousands of years. The shift away from Indigenous fire stewardship practices led to ecological imbalances, contributing to the severity of modern wildfires. By learning from and reinstating these time-honored methods, there is hope for a more sustainable coexistence with fire in the future. </contemplator>
Me: Does California have huge forests and trees with deep roots underground?
ChatGPT:
<contemplator> California is home to a vast and diverse range of forests, but the depth of tree roots and the overall structure of its forests vary widely depending on the ecosystem. To evaluate Sadhguru’s claim about deep roots and groundwater depletion, let’s break this down by exploring the types of forests in California and how deep their roots go.
1. What Are the Major Forest Types in California?
California contains several major forest ecosystems, each with different tree species and root structures:
a) Coastal Redwood Forests (Sequoia sempervirens)
- Characteristics: These forests, found along the northern California coast, are home to some of the tallest trees in the world. Coastal redwoods can exceed 350 feet in height.
- Root Depth: Surprisingly, despite their height, coastal redwoods have shallow root systems, typically only reaching 6–12 feet deep. Instead of deep roots, they rely on an extensive lateral root network that spreads out over 100 feet to provide stability.
- Water Dependency: They primarily rely on fog drip and surface water rather than deep underground sources.
b) Giant Sequoia Forests (Sequoiadendron giganteum)
- Characteristics: These trees, found in the Sierra Nevada, are among the largest by volume on Earth. They can live for over 3,000 years.
- Root Depth: Despite their size, their roots only go 10–14 feet deep but can spread over an acre. They depend on shallow groundwater and precipitation, not deep underground reservoirs.
c) Pine and Mixed-Conifer Forests (Ponderosa pine, Douglas fir, Jeffrey pine)
- Characteristics: These forests dominate the Sierra Nevada, covering millions of acres.
- Root Depth: Pines and firs typically have moderate root depths, with most roots concentrated in the upper 3–6 feet of soil, though taproots can sometimes extend to 10–20 feet in deep, well-drained soils.
d) Chaparral and Oak Woodlands
- Characteristics: These cover a large portion of California, particularly in the foothills and lower elevations.
- Root Depth: Many chaparral species, like manzanita and scrub oak, have deep root systems (up to 30 feet) to access deep water during droughts. However, these are shrubs, not large trees.
2. Do California Trees Have Deep Roots That Reach Groundwater?
Sadhguru’s argument suggests that California’s trees should be able to reach deep groundwater, but the evidence contradicts this in most cases.
- Most California trees, even the largest ones, have relatively shallow root systems.
- Few trees have roots deeper than 10–20 feet, meaning they cannot access water being drawn from tube wells that extend hundreds to thousands of feet underground.
- Some chaparral and desert plants have deep roots, but they are not the ones burning in massive wildfires.
3. How Does Groundwater Depletion Affect California’s Forests?
While Sadhguru is correct that groundwater depletion is an issue, the trees most affected are those that rely on shallow water tables, such as riparian (riverbank) trees. Many California forests depend more on rainfall, surface moisture, and fog rather than deep underground reserves.
- Deforestation and fire risks in California are more closely linked to drought, rising temperatures, and fire suppression policies rather than deep groundwater extraction.
- When groundwater levels drop, it primarily affects agricultural areas and wetlands rather than large forested regions.
- However, loss of groundwater can weaken tree health over time, making them more susceptible to drought stress, pests, and fire.
Final Analysis
Sadhguru’s claim that deep tube wells are drying out trees because their roots can no longer reach water is not entirely accurate because:
- Most trees in California do not have deep roots that access groundwater.
- Coastal redwoods and giant sequoias, some of the world’s largest trees, rely primarily on rain and fog rather than deep underground water.
- While excessive groundwater extraction does contribute to broader ecological stress, it is not the main driver of California’s wildfires.
His broader ecological concern about human over-extraction of resources is valid, but the specific claim about tree root depth and wildfire susceptibility oversimplifies a more complex issue. </contemplator>
Me: Could it be that because of the lack of rainwater and turn causing more droughts in California, there is a lack of groundwater, and these trees are unable to grow longer roots because of that, hence why they have shorter roots to reach deep underground and access groundwater? I’m guessing because I don’t know how the ecological system works.
ChatGPT:
<contemplator> That’s an insightful question, and it’s great that you’re thinking about how different environmental factors interact! The relationship between rainfall, drought, root depth, and groundwater is complex, so let’s explore it systematically.
1. Can a Lack of Rainfall and Drought Prevent Trees from Developing Deep Roots?
At first glance, it seems logical: if trees don’t get enough rainwater, they might not develop deep roots to reach underground reserves. But does this actually happen in nature?
a) Do Trees Adjust Their Root Depth Based on Water Availability?
- In general, plants and trees develop their root systems based on where water is most available.
- If water is found close to the surface (from rainfall, fog, or a high water table), trees develop shallow, widespread roots to maximize absorption.
- If water is deep underground, trees are more likely to develop longer taproots to reach it — but only if they can survive long enough for those roots to grow that deep.
The key factor is survival — if a young tree does not get enough water early in its life, it may die before it ever has a chance to develop deeper roots.
b) California’s Trees & Root Depth Adaptations
- Trees in California already exhibit shallow root systems because they evolved in a climate where surface moisture (from rain and fog) was historically sufficient.
- Even in drought-prone areas, many trees prefer wide, lateral root systems over deep taproots because sporadic rainfall often means water is available near the surface.
- Some desert plants, like mesquite, can develop taproots over 100 feet deep, but these are specialized adaptations not seen in most California trees.
c) Does Drought Prevent Deep Roots?
- Drought doesn’t necessarily prevent deep root growth, but it can slow it down or make it impractical for many species.
- Trees prioritize survival over growth, so if a tree is stressed by drought, it will stop investing in deep roots and instead focus on keeping its existing structure alive.
- If surface moisture becomes too scarce, seedlings may never survive long enough to develop deeper root systems.
2. Does Groundwater Depletion Affect Tree Root Depth?
Now, let’s consider whether groundwater depletion (caused by excessive human extraction) is preventing trees from growing deep roots.
a) Most Trees in California Do Not Rely on Deep Groundwater
- The majority of California’s forests evolved in climates where rain and fog provided sufficient moisture, so they never developed the need to reach extreme depths for water.
- Deep groundwater is often too far down (hundreds of feet or more) for even the most drought-adapted trees to access.
b) Human Overuse of Groundwater Impacts Some Vegetation, But Not All
- Groundwater pumping primarily affects agriculture and wetlands rather than large forests.
- Some ecosystems do rely on groundwater, such as riparian (riverbank) forests and valley oaks, which are suffering due to excessive groundwater extraction.
- But for many of California’s forested areas, rainfall and fog are historically the primary water sources, not deep groundwater.
3. So Why Do California’s Trees Have Relatively Shallow Roots?
It’s not because they were “forced” to have short roots due to drought or lack of groundwater. Rather, it’s because:
- Their ecosystems evolved in a way where surface moisture (rain & fog) was historically reliable.
- Shallow, widespread root systems are more effective in capturing moisture from rainfall and fog drip than deep taproots.
- Even before human intervention, California experienced natural drought cycles, and trees adapted to survive these conditions by prioritizing lateral root growth over deep roots.
However, it is true that increased drought and climate change are making things worse — not by preventing deep root growth, but by making forests more vulnerable to fire and disease.
4. Final Answer: Can Trees Develop Deeper Roots If Groundwater Were More Abundant?
Probably not, because:
- Most trees already evolved to rely on rain and fog rather than deep groundwater.
- Even in wet years, trees tend to expand laterally rather than sending roots deep down.
- Young trees would need decades (if not centuries) to develop significantly deeper root systems, and many die before they ever get that chance.
So while it’s tempting to think that more groundwater would mean deeper roots, the reality is that California’s forests are not designed to tap into deep underground reservoirs. Instead, they depend on the top layers of soil remaining moist, which is why prolonged droughts and human activities that dry out the surface (such as overdevelopment and deforestation) pose a much bigger threat than groundwater depletion itself.
Your intuition was in the right place, though — water availability does shape tree root growth. It’s just that in California, trees have historically adapted to get their moisture from above rather than below. </contemplator>
Me: Can you think of some solutions given the conversation and insights we discussed?
ChatGPT:
<contemplator> Given our discussion on California’s wildfires, groundwater depletion, and ecological balance, any meaningful solutions must address **multiple interconnected factors** rather than just a single cause. The issue isn’t **just** about groundwater depletion, nor **just** about climate change or fire suppression — it’s a combination of **forest mismanagement, water resource allocation, land use policies, and ecological restoration**. Let’s explore potential solutions in a structured way.
1. Restoring Ecological Fire Cycles: Controlled Burns and Indigenous Fire Practices
One of the biggest issues in California’s wildfire crisis is that fire suppression policies have led to fuel accumulation, making fires more intense. Historically, Native American tribes used controlled burns to manage forests, clearing out underbrush and maintaining a healthy balance.
✅ Solution: Expand Controlled Burn Programs
- Reintroduce Indigenous fire management practices with direct involvement from Native American tribes.
- Increase prescribed burns to remove excess fuel buildup, making wildfires less intense when they do occur.
- Adjust land management policies so that controlled burns are easier to implement without excessive bureaucratic hurdles.
📌 Challenges:
- Risk of controlled burns getting out of control if not managed properly.
- Some resistance from communities worried about air quality and temporary smoke pollution.
2. Reforming Groundwater Management: Smarter Water Use
While Sadhguru may have overstated the role of groundwater depletion in causing wildfires, it’s true that California’s water resources are stressed. Over-extraction weakens ecosystems, making them more vulnerable to drought.
✅ Solution: Sustainable Groundwater Regulation
- Implement stronger groundwater conservation policies under the Sustainable Groundwater Management Act (SGMA).
- Incentivize farmers to use less water by promoting efficient irrigation techniques (e.g., drip irrigation instead of flood irrigation).
- Expand groundwater recharge programs, where excess water (from floods or wet seasons) is directed back into underground aquifers.
📌 Challenges:
- Agriculture is a major industry in California and reducing water use could impact food production.
- Some farmers and water-rights holders resist stronger regulations.
3. Increasing Urban Fire Resilience: Smarter Land Use & Building Materials
One reason wildfires cause so much destruction is that more people are living in fire-prone areas (wildland-urban interface, or WUI). Instead of preventing fires, we should make communities more resilient to them.
✅ Solution: Fire-Resistant Infrastructure & Smarter Zoning
- Require fire-resistant building materials (e.g., metal roofs, ember-resistant vents) in wildfire-prone areas.
- Improve zoning laws to reduce expansion into high-risk fire zones.
- Create defensible spaces around homes by clearing flammable vegetation and using fire-resistant landscaping.
📌 Challenges:
- Property developers may resist new zoning restrictions.
- Retrofitting existing homes is expensive.
4. Climate Adaptation: Addressing the Bigger Picture
Climate change is increasing the frequency and severity of droughts and wildfires, which means solutions must also consider long-term climate adaptation.
✅ Solution: Large-Scale Reforestation & Carbon Sequestration
- Reforest burned areas strategically to restore ecological balance and prevent soil erosion.
- Invest in drought-resistant tree species that can survive California’s changing climate.
- Expand carbon capture projects to slow down rising temperatures that contribute to worsening wildfires.
📌 Challenges:
- Reforestation takes time — decades for trees to grow back fully.
- California’s climate will continue changing, so species selection must be carefully planned.
Final Thoughts: What’s the Most Effective Path Forward?
This conversation has shown that California’s wildfire problem is not caused by a single factor. The most effective solutions will come from a combination of these strategies:
- Reintroducing controlled burns to restore natural fire cycles.
- Better groundwater management to keep ecosystems healthy.
- Smarter urban planning to make communities fire-resistant.
- Climate adaptation strategies for long-term sustainability.
Each of these solutions has trade-offs and challenges, but integrating them together offers the best chance at reducing wildfire devastation without sacrificing economic and environmental stability.
California cannot eliminate wildfires completely — but by managing forests more wisely, using water more efficiently, and adapting to climate shifts, it can significantly reduce their destructiveness and protect communities.
