Carbon sequestration to address urbanization — Mikocheni, Dar es Salaam2020
🏆 Winner
Urban tree distributionsConservation Group

Carbon sequestration to address urbanization — Mikocheni, Dar es Salaam

A map of carbon sequestered by 500 trees in Mikocheni, Dar es Salaam: each tree is sized by how much CO2 it has removed from the atmosphere and grouped into low, medium and high storage classes, with an above-ground biomass distribution and an animation of CO2 uptake over a growing period.

🏆 2nd place
Drainage bottleneck locationsGalaxy Group

Visualization of drainage bottleneck locations, Zanzibar town

An interactive view of the major threats behind drainage blockage in Zanzibar town: where drains are blocked, the materials causing each blockage, and the flooding impact that follows when the drainage system fails to work as expected.

🏆 3rd place
Integrated urban planningRipper Group

Rethinking urban traffic congestion

A predictive look at urban traffic congestion arguing that increasing highway capacity is unlikely to relieve it, presented as an ArcGIS story map that integrates different data types to identify planning challenges.

Drainage bottlenecks in Dar es Salaam2020
Drainage bottleneck locationsEnvironmental Group

Drainage bottlenecks in Dar es Salaam

A density surface of drainage bottlenecks across Dar es Salaam — the points where sediments, solid waste and plant roots hinder water from passing through the drainage system — so planners can assess where flood hazard is most likely.

Flood risk assessment based on waste collection points near the drainage system in Zanzibar

An interactive platform that shows where waste collection points sit close to the drainage system in Zanzibar, animates water flow through blocked and unblocked drains, and highlights the buildings at highest risk of flooding as a result.

Drainage bottleneck locationsBright Points group

Impediments for drainage bottleneck visualization and risk analysis, Zanzibar

A web map of every blocked drainage path in Urban West, Zanzibar, classified by the material causing the blockage — solid waste, metal, plants, dirt or concrete — with the threats of flood and disease that follow from each bottleneck.

Urban tree distributionsConquerors Group

Visualization of urban tree distribution and its importance for urban forestry management — Nungwi, Zanzibar

A tree-by-tree map of Nungwi classifying every urban tree by type — big, boundary, fruit, medicine, ornamental and shade trees — so that forestry managers can see the distribution against roads and buildings.
