Walk a litter and erosion transect along the Rufisque coastline.

Rufisque's coastline, part of the greater Dakar region, has lost significant ground to erosion over recent decades, with the sea now reaching homes and roads that once stood well back from the water, and litter builds up in the same eroding zone. A walked transect from stable ground above the erosion line records both conditions together.

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 — recorded, and readable any time at vealth.net/labor/credit/(your wallet). 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.

Steps

1. Walk a fixed transect line along the coastline from stable ground above the erosion line.
2. Photograph each eroded stretch and litter cluster with a visible reference point.
3. Note the approximate distance from the water to any structure at risk.
4. Count and categorize litter density at set intervals along the transect.
5. Record the GPS point and date for every photo.
6. Submit the survey log with photos attached.

What counts as done

• GPS-tagged photos of each stretch
• Distance-to-structure note per stretch
• Survey log with date

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.
