Build a terraced garden bed on the upper slope above the Msimbazi valley

Families living above the flood-prone Msimbazi valley have little safe flat ground to grow food, but a small terraced bed built on the upper slope, well above the flood line, can still produce real vegetables. This build turns unused slope into a working garden. Standard: FAO urban agriculture guidance; SDG 2.4 Proof: photo of finished garden bed Method (FAO urban agriculture guidance; SDG 2.4): 1. Confirm the community-invited site well above the flood line. 2. Clear loose debris and level a small terrace by hand. 3. Build a simple retaining edge for the bed using available materials. 4. Fill the bed with soil and a starter layer of compost. 5. Photograph the finished bed and log the date. Done when: photo of finished garden bed

$220 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: USDA/SARE sustainable vegetable production + Cooperative Extension Master Gardener practices; People's Garden bed establishment. Hand-tool, DIY-safe food growing on tested/known-clean soil or raised beds.

Bring

• GPS-capable phone
• camera
• garden fork/broadfork + hand trowel
• finished compost + rake
• seeds or transplants (labeled)
• mulch (straw/leaf)
• watering can or hose

Steps

1. 1. Confirm the bed location inside the posting radius; record the GPS waypoint and photograph the bed before work.
2. 2. Clear weeds and debris; loosen the top 8-12 inches with a fork/broadfork without inverting the soil profile.
3. 3. Spread 1-2 inches of finished compost and rake the bed level.
4. 4. Sow seeds to the depth/spacing on the packet, or set transplants at their correct depth, in labeled rows.
5. 5. Water in gently to settle the soil around seeds/roots.
6. 6. Apply a light straw/leaf mulch between rows to hold moisture, keeping it off seedling stems.
7. 7. Record the crop plan, spacing, and a watering/harvest cadence for the next visit.
8. 8. Enter crop list, GPS, before/after photos, and the care cadence into the proof record; sign.

If it does not match the plan

• Soil is untested near a pre-1978 structure, old orchard, or roadway (possible lead/contaminant) -> do not plant edibles in-ground; use a raised bed with clean imported soil and flag for a soil test.
• Out-of-season crop or a hard frost in the forecast -> adjust the crop choice or protect with cover; do not sow into a predictable loss.
• Signs of active pest/disease on transplants -> reject the affected stock and note it; never introduce a known infestation to the bed.

What counts as done

• GPS waypoint recorded inside the posting radius
• Before and after photos of the planted bed
• Crops sown/transplanted at packet-correct depth and spacing, in labeled rows
• Bed watered in and mulched, with a watering/harvest cadence recorded

Proof is measured against these, not judged by taste.
