Yesterday the bare plot looked different once boots marked it. Mr James, Kenya Forest Service officer for Lang'ata Constituency, walked the line with Mr Ken from Kamukunji. ETCO hosted alongside the Lang'ata Local Water Forum and the Highrise Youth Generation Group.

We pointed out where water could reach, where shade fell, where the first beds might sit. The plan is straightforward: prepare the site, train Climate Worx cohorts, then plant at least 10,000 seedlings to help keep Nairobi Dam Park cared for over the years.

Paper turned into pacing. That is how a nursery stops being an idea and becomes rows.

When the first community planting day is fixed, we will publish the date — bring sturdy gloves; we lend spades when the line grows.
