The Hidden Cost of Our Food
How Simplified Landscapes Are Eroding Our Connections to Nature
Explore the ResearchIntroduction: More Than Just a Pretty View
What happens when we replace messy, diverse nature with neat, efficient farmland? At first glance, the transformation might seem like progress—orderly rows of crops stretching to the horizon, streamlined operations maximizing food production. But this landscape simplification comes with hidden costs that extend far beyond the obvious environmental impacts we often hear about.
Across the globe, from the soy monocultures of the Amazon to the palm oil plantations of Southeast Asia and the intensively farmed landscapes of Europe, traditional agricultural landscapes are being transformed into simplified systems focused primarily on crop production 1 . While this shift has undoubtedly increased agricultural yields, researchers are discovering that it damages something profound yet difficult to measure: our relational values—the meaningful relationships we have with nature and with each other through nature 1 .
This article explores how the simplification of our landscapes is not just an ecological crisis but a social and cultural one, eroding the connections that define what it means to be human in a more-than-human world.

What Are Relational Values and Why Do They Matter?
Understanding Our Deep-Seated Connections to Nature
Relational values represent a revolutionary way of thinking about why nature matters to us. They move beyond the traditional divide between seeing nature as having either intrinsic value (valuable for its own sake) or instrumental value (valuable for what it provides us) 1 . Instead, relational values focus on the meaningful relationships we have with nature and with each other through nature .
Think about what it feels like to walk through a familiar landscape where you've spent time with loved ones, or the sense of responsibility you might feel toward protecting a local natural area. These aren't just about what you can get from nature, nor are they purely about nature's inherent rights—they're about the relationships and connections that give meaning to our lives 1 6 .
The Erosion of Invisible Wealth
When landscapes become simplified, we lose more than just biodiversity. Research shows that this process can erode:
-
Human-nature connectednessAs landscapes become less diverse and interesting, our emotional and experiential connections to them weaken 1
-
Social relationshipsMany of our social interactions are mediated through nature—think community gardening, fishing trips, or neighborhood walks—and these can deteriorate as landscapes simplify 1
-
Cultural identityTraditional practices, local knowledge, and sense of place are often deeply tied to specific landscape features that disappear in simplified systems 6
-
Sense of agencyWhen power shifts to distant corporations and decision-makers, local people often feel less able to influence what happens to their landscapes 1
Table 1: How Landscape Simplification Affects Relational Values
| Aspect of Relational Values | Diverse Landscape | Simplified Landscape |
|---|---|---|
| Human-Nature Connection | Strong, multifaceted | Weakened, limited |
| Social Relationships | Community-based, cooperative | Often fragmented |
| Cultural Identity | Strong, place-based | Eroded, homogenized |
| Sense of Agency | Local decision-making | External control |
| Knowledge Systems | Diverse, local | Standardized, external |
The Ecological Engine of Connection: How Biodiversity Supports Relationships
The Hidden Mechanisms Behind Our Connections
The erosion of relational values isn't just a social phenomenon—it's driven by concrete ecological changes. Simplified landscapes fundamentally alter how ecosystems function, which in turn affects how we experience and relate to them.
Recent research has revealed that landscape simplification acts as an ecological filter, systematically removing certain types of species while allowing others to thrive 3 . This process leads to biotic homogenization—ecosystems becoming more similar to each other, dominated by the same generalist species wherever you go 3 .
Complex landscapes support diverse species interactions
The Specialists Disappear First
What's particularly revealing is how this filtering works. Studies examining multiple arthropod orders—from spiders and beetles to butterflies and bees—have found that landscape simplification consistently selects against species with specialized feeding habits, shorter activity periods, and relatively smaller body sizes 3 . The specialists disappear, leaving only generalists behind.
This matters for relational values because much of what we find interesting, beautiful, or meaningful about nature comes from its diversity and uniqueness. When every landscape starts to look and function the same, our opportunities for forming distinctive relationships with particular places diminish.
Table 2: How Landscape Simplification Filters Species Traits
| Trait | Complex Landscapes | Simplified Landscapes |
|---|---|---|
| Feeding Habits | Mix of specialists and generalists | Dominated by generalists |
| Activity Period | Varied, throughout year | Concentrated, seasonal |
| Body Size | Range of sizes | Larger species favored |
| Dispersal Ability | Mix of good and poor dispersers | Good dispersers favored |
| Reproductive Rate | Varied strategies | Fast-reproducing species favored |
Specialist Species
Highly adapted to specific conditions but vulnerable to environmental changes
Generalist Species
Adaptable to various conditions, thrive in simplified landscapes
Biotic Homogenization
Ecosystems become more similar as unique species are replaced by widespread ones
A Closer Look: The Wild Plant Experiment
Unraveling the Ecological Domino Effect
To understand exactly how landscape simplification affects ecosystems—and ultimately our relationships with them—let's examine a sophisticated field experiment conducted in New York's Finger Lakes region 2 . Researchers investigated how landscape composition affects the reproduction of wild plants through complex interactions between herbivores and pollinators.
The study used an innovative approach with Barbarea vulgaris (yellow rocket), a wild plant species found in both natural and agricultural landscapes. The researchers worked across 14 sites representing a gradient from natural to highly simplified agricultural landscapes, using both naturally occurring plants and standardized "phytometer" plants grown in uniform conditions 2 .
Field research sites spanned a gradient of landscape complexity
Methodological Breakdown: Tracing the Causal Pathways
The experiment was designed to untangle the complex web of interactions that might affect plant reproduction:
Site Selection
Researchers identified 14 sites with varying proportions of agricultural land (1.24-79.55%) within a 1500-meter radius 2
Phytometer Plants
These laboratory-raised plants allowed researchers to study environmental effects without the complication of local adaptations 2
Insect Exclusion Treatments
Some plants were protected from herbivores to isolate their effects 2
Standardized Measurements
Researchers quantified herbivore damage, flower production, flower size, pollination success, and ultimately seed set 2
This comprehensive approach allowed scientists to move beyond simple correlations to identify causal pathways—exactly how landscape simplification affects plant reproduction through its effects on plant-insect interactions 2 .
Surprising Results: Cascading Effects Revealed
The findings revealed unexpected ecological domino effects:
-
PollinationThese larger flowers attracted more pollinators 2
-
Net effectDespite the pollination benefit, the reduction in flower numbers ultimately reduced total seed production 2
-
Local adaptationNaturally occurring plants showed different patterns than standardized plants, suggesting local adaptation 2
Perhaps most tellingly, naturally occurring plants showed different patterns than the standardized phytometer plants, suggesting that local populations had adapted to their particular insect communities 2 . This adaptation comes at a cost—the very process of adaptation represents a loss of flexibility and potential.
Table 3: How Landscape Complexity Affects Plant-Insect Interactions
| Variable | Simple Landscapes | Complex Landscapes |
|---|---|---|
| Herbivore Damage | Lower | Higher |
| Flower Number | Higher | Lower |
| Individual Flower Size | Smaller | Larger |
| Pollinator Visitation | Reduced | Enhanced |
| Final Reproductive Output | Context-dependent | Context-dependent |
| Evidence of Local Adaptation | Yes | Yes |

- Identify feedback loops between ecological and social systems
- Develop more effective conservation and management strategies
Beyond the Fields: Implications and Solutions
The Pesticide Paradox
The ecological changes driven by landscape simplification often create feedback loops that further accelerate the process. For instance, a 13-year study of Spanish vineyards found that pest outbreaks increased four-fold and insecticide applications doubled in simplified, vineyard-dominated landscapes compared to complex landscapes with semi-natural habitats 7 .
This creates a vicious cycle: simplification reduces natural pest control, leading to more pesticide use, which further simplifies the landscape 7 8 . Quantitative synthesis studies have found that landscape simplification reduces natural pest control by about 46% 8 , demonstrating how the loss of biodiversity directly undermines the ecosystem services that make landscapes resilient.
Simplified landscapes often require more pesticide inputs
Cultivating Connections: A Path Forward
The evidence clearly shows that landscape simplification erodes both ecological function and human connections to nature. But this understanding also points toward solutions:
Conserve Heterogeneity
Maintain diverse land cover types rather than creating monolithic agricultural expanses 3
Support Local Agency
Ensure local communities have meaningful input into landscape management 1
Document Values
Make these often-invisible values visible in policy decisions
Research consistently shows that landscape-level complexity can buffer the negative effects of local management intensity 3 . Even in landscapes with intensive local management, maintaining diverse habitat types at the broader scale helps preserve both ecological function and the potential for human connection.
Conclusion: Revaluing Our Relationships
The erosion of relational values through landscape simplification represents a silent crisis—one that's difficult to measure but profoundly affects human well-being and our potential for sustainable coexistence with nature.
As we face escalating environmental challenges, from biodiversity loss to climate change, recognizing the importance of relational values offers a path forward. By designing and managing our landscapes to maintain diversity, complexity, and meaning, we can support both ecological function and human flourishing.
The science is clear: the relationships we maintain with nature and with each other through nature are not luxuries to be preserved after taking care of "serious" concerns like food production. They are essential components of sustainable societies. By recognizing the hidden costs of landscape simplification and taking steps to foster diverse, meaningful human-nature relationships, we can cultivate landscapes that nourish both our bodies and our spirits.
