Landscape architects, planners, builders and public agencies can connect food production, waste prevention, ecological systems, public health and community priorities in the same project brief. That is the central argument made by April Philips in an article published by the ASLA Northern California Chapter on May 27, 2021. It is a professional design position, not a controlled study proving that any single landscape intervention causes a measured climate result.
For current decisions, pair that systems approach with the U.S. Environmental Protection Agency’s 2023 Wasted Food Scale. The scale places preventing wasted food, donating edible food and upcycling food among the most environmentally preferable pathways it assessed. Landfill, incineration and sewer disposal rank among the least preferable. The scale evaluates environmental performance only; it does not determine whether a strategy is affordable, equitable or socially acceptable.

What Eat, Plant, Drawdown means in practice
The title links three actions that are often planned separately. Eat represents the food system: how food is grown, distributed, prepared, consumed and discarded. Plant represents living infrastructure, from productive soil and street trees to community gardens, habitat and water-retaining landscapes. Drawdown represents reducing greenhouse-gas concentrations by avoiding emissions and supporting removal where credible.
Philips argues that a city cannot become climate-ready by designing roads, buildings, parks and utilities in isolation from food. A neighborhood’s food access, soil, shade, stormwater, waste streams and social networks affect one another. A productive landscape may provide food and habitat while also managing heat and rain. A waste-prevention program may reduce methane while improving the reliability of local food assistance. These are connections to test in a project, not guaranteed outcomes to claim without measurement.

“The garden suggests there might be a place where we can meet nature halfway.” — Michael Pollan, as quoted by April Philips in the 2021 article.
Why food belongs in climate-responsive planning
Food systems use land, energy and water
Every meal carries impacts from production, processing, refrigeration, transport, retail and preparation. A site plan that preserves a wetland but ignores a large organic-waste stream is addressing only part of its environmental context. Conversely, a garden that requires imported soil, intensive irrigation and frequent replacement may undermine some of its intended benefits. The design question is therefore not whether a project is labelled green, but how its complete food and ecological system performs over time.
Food connects adaptation and mitigation
Adaptation protects people from climate hazards such as extreme heat, drought, flooding and supply interruptions. Mitigation reduces emissions or increases credible carbon storage. Shade trees, healthy soils, rain gardens and edible planting can support adaptation, while avoiding wasted food and choosing lower-emission materials can support mitigation. Their value depends on maintenance, water availability, species selection, construction methods and the behavior of the people who use the place.
Food is also a public-health and community issue
Markets, gardens, kitchens and gathering spaces can make healthy food more visible and useful. Yet a landscape project cannot prove improved nutrition or food security merely because it includes planting. Access, affordability, cultural fit, safe paths, operating hours and long-term stewardship must be assessed with residents and service providers.
What current food-waste evidence says
The EPA’s 2023 Wasted Food Scale compares pathways by environmental performance. Its ranking updates broad advice that previously treated all forms of organic-waste diversion as equivalent. Prevention is better than managing an avoidable waste stream after it exists.
| Pathway | EPA environmental position | Design implication |
|---|---|---|
| Source reduction | Among the most preferred options | Prevent overproduction, purchasing errors and oversized portions before food becomes waste. |
| Donation | Among the most preferred options | Design safe, reliable collection and cold-storage procedures for edible surplus. |
| Upcycling | Among the most preferred options | Convert ingredients or by-products into new food products where food-safety rules allow. |
| Recycling into soil amendments | Can improve soil structure and soil health | Use an appropriate composting or other soil-amendment system, with contamination controls and a responsible end use. |
| Landfill | Among the least preferred options; EPA identifies sizeable methane emissions | Separate organics and reduce the volume sent to disposal. |
| Sewer or wastewater treatment | Among the least preferred options; EPA identifies sizeable methane emissions | Do not use drains as a routine food-waste outlet. |
| Incineration | Among the least preferred options in the scale | Consider prevention and higher-value pathways first. |
The scale does not score labor conditions, affordability, access, cultural priorities or distributional equity. A project team should therefore use it alongside locally gathered social and economic evidence rather than presenting an environmental ranking as a complete policy decision.
Use the foodshed as a design map
Philips proposes thinking about a foodshed by analogy with a watershed. A watershed traces how water moves through a place; a foodshed traces relationships among production, processing, distribution, consumption and disposal. Mapping those relationships can reveal leverage points that a parcel-by-parcel site analysis misses.

Map origins and destinations
Identify where food entering the project comes from, where edible surplus goes, where unavoidable scraps are handled and which communities are served or excluded. Include farms, wholesalers, schools, restaurants, food banks, compost facilities, transfer stations and transit routes when they influence the project.
Rank #3
Find physical opportunities
Look for underused roofs, rights-of-way, courtyards, vacant parcels, greenhouse locations, shade opportunities, water-storage areas and spaces for safe loading. Confirm ownership, soil quality, utilities, access, fire separation, accessibility and maintenance responsibility before drawing a garden or market.
Connect the map to decisions
A foodshed map should change the plan. It might justify a receiving area for donated food, a community kitchen, a cooler with backup power, a compost staging zone, edible tree planting near a public route or a partnership with a nearby grower. If the map produces no change in budgets, specifications or operations, it is only an illustration.
A project workflow for climate-smart food design
- Set a combined brief. Add food access, waste prevention, habitat, heat, water, public health and community stewardship to the normal program. Assign an owner for each objective.
- Establish a baseline. Record existing food-waste quantities and destinations where data are available. Document shade, soil, irrigation demand, embodied materials, maintenance hours, flood exposure and user access. Mark unknowns instead of filling them with assumptions.
- Engage people who run the system. Interview residents, growers, sanitation staff, food-service operators, public-health workers, maintenance crews and local organizations. Ask who pays, who works, who benefits and who bears nuisance or risk.
- Prioritize prevention. Change purchasing, portioning, storage, menu planning and event procedures before selecting a disposal technology. Build donation and upcycling routes for edible material that cannot be prevented.
- Design the living infrastructure. Select plants and soils for the site’s climate, water budget, habitat goals and expected care. Include accessible paths, safe work areas, tool storage, irrigation controls and spaces for teaching or gathering.
- Coordinate construction. Protect existing soil, keep clean organics separate from demolition debris, specify durable materials and provide temporary protection for retained trees and planting zones. Coordinate deliveries so food-related equipment does not conflict with construction logistics.
- Write the operations plan. State who harvests, waters, repairs, cleans, sorts donations, checks temperatures, removes contamination and reports problems. Include a funded replacement cycle for equipment and plants.
- Measure and adjust. Track waste prevented, donated and upcycled; contamination rates; soil and irrigation performance; maintenance labor; participation; and access outcomes. Review results seasonally and after major events.
Design strategies that connect planting and food
Productive public landscapes
Edible streetscapes, orchards, school gardens and community plots can combine food production with shade, habitat and social use. Specify harvest rights, pruning responsibilities, sanitation, visibility and replacement planting. Fruit that is inaccessible or routinely left to rot is not a successful food strategy; the operating model matters as much as the planting plan.
Soil and compost systems
Composting can return organic matter to soil, but it is not a substitute for preventing avoidable waste. Size a system for the actual feedstock, control contamination, manage odors and leachate, and identify where finished material will be used. Keep food scraps, landscape trimmings and construction materials in compatible streams only when the receiving facility accepts them.
Rank #4
Water-sensitive food landscapes
Pair edible planting with rainwater capture, infiltration and efficient irrigation where regulations and public-health requirements permit. Keep overflow paths clear, separate potable and non-potable systems, and select crops that can survive the site’s dry periods. A water feature that depends on unreliable trucked water may be less resilient than a smaller, well-maintained planting area.
Food hubs and shared facilities
Community kitchens, markets, cool rooms and aggregation spaces can shorten handoffs between growers and eaters. They require loading access, power, drainage, pest control, fire protection, accessibility and a governance model. A beautiful market pavilion without a vendor schedule or maintenance budget will not create a functioning food network.
Carbon accounting: useful, but not automatic
Philips’s article mentions tools including Pathfinder and Climate Positive Design in the context of project decisions. Those descriptions belong to the 2021 article; calculation methods, interfaces and assumptions may have changed, so verify current documentation before relying on a result.
For any calculator or spreadsheet, disclose the boundary and assumptions. A useful comparison includes:
Best Value
- material quantities and their embodied emissions;
- construction equipment, transport and replacement cycles;
- operational energy, irrigation and refrigeration;
- soil-carbon or vegetation-sequestration assumptions, including permanence and maintenance;
- resilience benefits that are not carbon credits, such as shade or flood buffering;
- capital cost, operating cost and available labor; and
- community goals, access and potential displacement.
Do not present a modeled sequestration value as an offset unless the accounting standard, verification, permanence and leakage risks are established. Carbon is one decision lens, not a proxy for every public benefit.

The EPA scale explicitly omits economic and social factors. A donation route may reduce environmental impacts but still fail if it requires unpaid labor, excludes people without transportation or sends food only to neighborhoods with existing services. A community garden may create benefits while raising concerns about land tenure, policing, cultural fit or future rent increases.
Set equity questions beside environmental metrics: Who can reach the site without a car? Are produce and classes affordable? Are languages, disabilities and cultural food practices accommodated? Who controls the land and data? Are paid positions available for care work? Publish decisions and create a process for changing them when residents report harm.

Common failure modes and fixes
| Failure | Why it happens | Fix |
|---|---|---|
| Composting is added while purchasing stays unchanged | Downstream equipment is easier to specify than behavior change | Set a source-reduction target and assign procurement owners before sizing compost capacity. |
| Planting is installed without a steward | Capital budgets cover installation but not care | Fund maintenance, training, harvest and replacement in the initial contract. |
| Carbon numbers are treated as facts | Model boundaries and assumptions are hidden | Publish inputs, ranges, time horizons and what the model excludes. |
| Food access is assumed from proximity | A map shows distance but not price, hours or safety | Measure affordability, opening times, mobility and resident experience. |
| Organics are contaminated | Bins, signs and collection responsibilities are unclear | Use consistent containers, simple instructions, monitoring and feedback. |
| Seasonal projects fail in extreme weather | Plant palettes and water systems ignore future conditions | Design for heat, drought, flooding and backup operations, then inspect after events. |
How to judge a proposal before construction
Use this review checklist with the design team, contractor and community partners:
- Does the proposal prevent avoidable food waste before specifying treatment?
- Are donation, upcycling and soil-amendment routes legal, safe and operationally funded?
- Are landfill, sewer and incineration volumes expected to decline, and is that claim measurable?
- Who owns the land, equipment, data and ongoing decisions?
- Does the planting plan fit the water budget, soil conditions and maintenance capacity?
- Are construction emissions, replacement cycles and equipment energy included in the comparison?
- Are benefits and burdens distributed fairly, with accessible participation?
- What will be inspected monthly, seasonally and after a climate event?
Further reading and the limits of the evidence
Drawdown, edited by Paul Hawken and published in 2017, is the book Philips references as a framework for considering climate solutions. The 2021 article also discusses historical hunger, food-insecurity, food-waste and solution-ranking figures whose original methods are not established here; treat those figures as dated rather than current benchmarks. More recent, attributable figures are available from the EPA’s June 12, 2024 release: the United Nations estimate, as cited by EPA, that global food loss and waste represent 8% of anthropogenic greenhouse-gas emissions, or 4.4 gigatons of carbon-dioxide equivalent annually; and the USDA estimate, as cited by EPA, that one-third of available food goes uneaten. Separately, EPA’s 2023 summary of From Field to Bin states that over one-third of food produced in the United States is never eaten. Each figure has a different source and geographic scope.
The practical conclusion is straightforward: design food, landscape and waste systems together, put prevention ahead of disposal, and test climate claims against real operating data. A project becomes more resilient when its ecological performance, construction decisions and community governance reinforce one another.
