How Many People Can We Feed Estimator (GTG Signature)
Estimate food production and people fed across Personal/Household, Garden/Property, Community/Organization, and Program/Donor.
Generates a GTG Food Impact Score (0–100), yield estimates, value, water-savings overlay, and a share-ready summary.
Educational tool — not agronomic, engineering, or compliance-grade measurement.

Select a mode, enter inputs, and get instant people-fed estimates + GTG score (saved locally).
Educational note: This estimator uses simplified yield proxies to compare scenarios and plan projects.
For real reporting, validate with harvest logs, weights, and distribution records.
👤 Personal/Household (home garden)
🌱 Garden/Property (larger site)
🌍 Community/Org (project scale)
💰 Program/Donor (funding impact)
Personal mode is the default. Garden/Community focus on acreage/area and distribution. Donor converts funding to impact.
Defines what “people fed” means (vegetable servings).
Used to convert pounds → servings.
Educational grocery value overlay.
Square feet (beds + containers).
Used to annualize production.
Adjusts yield and water realism slightly.
Affects yield and water efficiency.
Waste reduces edible servings delivered.
Boosts yield resilience and GTG score.
Crop mix shapes yield density. Perennials stabilize long-term productivity.
