Clear a stretch of Tunis's coastline of litter (2026-08-03)

The lagoon and coastal stretches near Tunis collect plastic and debris fast, especially near dense outer districts where storm drains empty straight to the water, a cleared stretch is a small, direct fix. Standard: UNEP / Ramsar coastal and nearshore habitat guidance, SDG 14 (Life Below Water). Proof: Before/after photos of the stretch plus bag count. Method (UNEP / Ramsar coastal and nearshore habitat guidance, SDG 14 (Life Below Water).): 1. Pick a public shoreline stretch of about 100 meters. 2. Collect litter and debris into bags, sorting recyclables where possible. 3. Photograph the stretch before and after. 4. Weigh or estimate the bags collected. 5. Dispose of bags at the municipal collection point the host names. Done when: Before photo with GPS pin and timestamp; After photo showing cleared stretch; Count/estimate of bags collected

Public shoreline, Tunis, Tunisia

Pay

$160 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.

Proof

Before/after photos of the stretch plus bag count.

This is exactly what gets it approved. Nothing settles without it.

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: NOAA coastal habitat (eelgrass / salt marsh) extent + condition

Bring

• tide table
• GPS phone
• quadrat frame
• measuring tape
• boots/waders
• camera

Steps

1. 1. Check the tide table; plan to work the low tide; tell someone your plan and return time.
2. 2. Navigate to the habitat edge; record GPS waypoints along the patch/edge.
3. 3. Photograph the meadow/marsh at low tide.
4. 4. Record shoot/stem density per quadrat and estimate patch extent (or edge scarp height for marsh).
5. 5. Note condition (epiphytes, dieback, wrack) and adjacent land use/armoring.
6. 6. Enter density, extent, condition, GPS, photos into the proof record; sign.

If it does not match the plan

• Soft mud / rising tide -> stop and retreat; safety over data.
• Edge retreat or heavy dieback observed -> flag for living-shoreline / protection planning.

What counts as done

• Before photo with GPS pin and timestamp
• After photo showing cleared stretch
• Count/estimate of bags collected

Proof is measured against these, not judged by taste.

The standard this serves

Coastal Habitat. Coastal habitat is the green fringe where land meets sea: eelgrass meadows, kelp beds, salt marsh. Acre for acre these are among the most life-giving places on Earth, nursery to the fish and buffer to the storm, and NOAA's assessment methods exist because they are quietly shrinking. Mastery looks like a person who can survey a stretch of shore and say, with evidence, whether the meadow is spreading or retreating. This packet is one piece of that watching: one site, one careful observation, one record added to the long ledger of the coast.
