Earth Forward hackathon entry. Demo environment.
EcoPulse helps communities turn fragmented environmental data into prioritized, measurable interventions: where to act first, what to do, and how to know if it worked.
EcoPulse is a demonstration of a workflow. It runs on simulated data for a fictional district, and it says so wherever numbers appear.
Environmental information exists, but communities often lack a simple way to translate it into prioritized action. Data sits in separate reports and dashboards, and the people most exposed rarely see it in a form they can act on.
EcoPulse combines environmental indicators, spatial visualization, intervention planning and scenario analysis in one workflow. It moves from sensing a problem to measuring whether the fix worked.
The goal is not simply to monitor environmental problems. The goal is to help people decide where to act first, what to do, and how they will know if it worked.
Sense
Six indicators, one index, and the change over the period you choose. Every number carries a plain-language meaning and a recommended action.

How clean the air is where people live and work, scaled 0-100. A higher score means cleaner air.
Recommended action. Cut exposure at the freight corridor and the kiln cluster first. They reach the most people.

How well local water supply covers household and farm demand, scaled 0-100. A higher score means lower stress.
Recommended action. Repair distribution losses and move farm irrigation to precision methods.

+1.7 pts (+3.3%) vs 90 days agoimproving
How much waste is collected and handled versus dumped or left, scaled 0-100. A higher score means less pressure.
Recommended action. Start doorstep segregation where dumping keeps returning.

+1.7 pts (+4.2%) vs 90 days agoimproving
How exposed residents are to dangerous heat, scaled 0-100. A higher score means lower risk.
Recommended action. Add shade and canopy where paving is dense and exposed residents are most numerous.

+1.7 pts (+3.6%) vs 90 days agoimproving
How much tree and vegetation cover a district has relative to its target, scaled 0-100. A higher score means more cover.
Recommended action. Plant along school grounds and street corridors in the lowest-coverage blocks.
55out of 100
+0.6 pts (+1.1%) vs 90 days agoimproving
A rough signal of habitat continuity and species-survey coverage, scaled 0-100. A higher score means healthier ecosystems.
Recommended action. Protect wetland edges and restore hedgerow links before more habitat is lost.
Weekly demo series. Dashed lines mark the Critical (45) and Moderate (60) thresholds.
The demo district is simulated. To see how the same 0-100 scoring behaves on real conditions, look up any place. Your browser asks Open-Meteo directly for current values. Nothing is stored and the demo district is not changed.
Understand
Marlow Basin is a fictional district built for this demonstration. District colour shows the score for the chosen layer. Markers are hotspots, sized by severity.
Choose a marker on the map, or pick from the heat risk hotspots below.
Prioritize
Hotspots ranked by a transparent priority score, so the first place to act is a calculation you can inspect rather than a guess.
Heat risk in Market Ward
High surface-temperature anomaly on a fully paved plaza with almost no shade.
Act
Choose the problem, compare the options, and turn one into a plan with a baseline, a target and a monitoring schedule.

Ratings out of 5 for the options above.
Select an intervention on the left to model it or plan it.
Prioritize and Act
Real programmes have a budget. Set an effort budget and EcoPulse selects the mix of interventions, at most one per hotspot, that delivers the most benefit where it matters most.
Effort points use the 1 to 5 effort rating of each intervention. Demonstration estimates
Method: exact dynamic programming over 16 hotspots and 37 options (multiple-choice knapsack). Value = hotspot priority x intervention benefit rating.
| Hotspot | Intervention | Priority | Effort | Value |

Act
Move the levers and see how the demonstration indicators respond. The point is to compare options, not to predict a number.

What the data is, how each number is produced, and what EcoPulse does not do.
| Class | In this demo | Detail |
|---|---|---|
| Demonstration data | Used | All district scores, hotspot records, populations, intervention ratings and community action numbers. Authored for this demo. |
| Derived indicators | Used | City-level scores (population-weighted district means), the Environmental Health Index, priority scores and scenario results. |
| User-entered data | Used | Action plans, progress logs and joins. Stored in the browser only, never sent to a server. |
| External or open data | Optional, live only | Open-Meteo current air quality and feels-like temperature, fetched in your browser. It can colour the Air quality and Heat map layers for a real region. The demo index and all other layers stay simulated. |
Dataset version 1.0.0. EcoPulse does not use machine learning, satellite imagery or IoT sensors. The only network call is the optional Open-Meteo lookup.
Environmental Health Index, using current demo values:
0.20 x 60.9 + 0.20 x 50.9 + 0.15 x 53.9 + 0.20 x 41.8 + 0.15 x 48.7 + 0.10 x 55.2 = 51.6
Status bands: Good 75 and above, Moderate 60 to 74, Poor 45 to 59, Critical below 45.
Hotspot priority = 0.5 x severity + 0.3 x population exposed + 0.2 x trend, each on 0 to 100. The index is a prioritization and visualization aid, not an official standard. The weights are demonstration choices and a real deployment would set them with local stakeholders.
Open-Meteo is the only source connected, and only for the live lookup. The rest are candidates for replacing the demo dataset.
