+ # Wildfire Smoke & Respiratory Outcomes in Sub-Saharan Africa
30
+
31
+ ## Abstract
32
+
33
+ A synthetic dataset modelling wildfire smoke exposure and respiratory health outcomes across three fire regime scenarios in sub-Saharan Africa. Each record represents an individual-month observation describing smoke PM2.5 exposure, fire proximity, vulnerability, respiratory symptoms, and health service utilisation. Africa accounts for over 70% of global burned area annually, with savanna fires in West/Central Africa and agricultural clearing burns in the Congo Basin driving massive seasonal smoke plumes.
34
+
35
+ ### Scenarios
36
+
37
+ - **Savanna Fire Belt**: West/Central African savanna fires (Nov-Mar) with widespread seasonal haze.
38
+ - **Forest Clearing Burn**: Congo Basin agricultural/forest clearing fires (Jun-Sep) with intense localised smoke.
39
+ - **Urban Peri-Urban Haze**: Cities downwind of fire zones with combined ambient + smoke pollution.
40
+
41
+ ## Dataset Structure
42
+
43
+ Each scenario contains 10,000 records (30,000 total). Key columns:
44
+
45
+ - `year`, `month`, `in_fire_season`, `age`, `sex`, `setting`
46
+ - `is_child_u5`, `is_elderly_60plus`, `pre_existing_asthma`, `pre_existing_copd`, `smoker`
47
+ - `pm25_smoke_ugm3`, `pm25_total_ugm3`, `aqi_category`
48
+ - `fire_proximity_km`, `smoke_days_per_season`, `fire_count`
49
+ - `mask_use`, `stayed_indoors`, `vulnerability_index`, `exposure_risk_score`
50
+ - `cough`, `wheeze`, `dyspnoea`, `eye_irritation`
51
+ - `ari_episode`, `asthma_exacerbation`, `copd_exacerbation`
52
+ - `er_visit`, `hospitalised`, `mortality`, `climate_fire_trend`
53
+
54
+ ## Parameterization Evidence
55
+
56
+ | Parameter | Value Used | Source | Year |
57
+ | --- | --- | --- | --- |
58
+ | Africa >70% of global burned area | Fire frequency baseline | GFEDv4, van der Werf et al. | 2017 |
59
+ | Savanna fire PM2.5 100-300 µg/m³ during fire season | Smoke exposure | Roberts et al., Atmos Chem Phys | 2009 |
60
+ | Forest clearing fires produce denser, localised plumes | Clearing scenario | Reddington et al. | 2015 |
61
+ | PM2.5 exposure increases ARI risk 1.5-3x | Dose-response | WHO AQG | 2021 |
62
+
63
+ ## Validation Summary
64
+
65
+ The 8-panel validation report (`validation_report.png`) confirms:
66
+
67
+ 1. **PM2.5 gradient**: Forest clearing has highest smoke PM2.5; urban haze adds ambient baseline.
68
+ 2. **Seasonality**: Clear monthly PM2.5 peaks during fire season months per scenario.
69
+ 3. **Symptoms**: Cough and eye irritation dominate; rates highest in forest clearing.
70
+ 4. **Exposure-ARI**: Higher exposure risk scores correlate with more ARI episodes.
71
+ 5. **Vulnerability**: Children <5 and elderly have highest vulnerability indices.
72
+ 6. **Health cascade**: ARI > ER visits > hospitalisation > mortality gradient realistic.
73
+ 7. **AQI**: Forest clearing has most "hazardous" days; urban haze more "unhealthy" days.
74
+ 8. **Fire proximity**: Closer fires produce higher smoke PM2.5 during fire season.

77
+
78
+ ## Usage
79
+
80
+ ```python
81
+ from datasets import load_dataset
82
+
83
+ ds = load_dataset("electricsheepafrica/wildfire-smoke-respiratory", name="forest_clearing_burn")
84
+ df = ds["train"].to_pandas()
85
+
86
+ # Fire season vs non-fire season ARI rates
87
+ print(df.groupby("in_fire_season")["ari_episode"].mean())
88
+ ```
89
+
90
+ ## Intended Uses
91
+
92
+ - Modelling wildfire smoke health impacts in SSA
93
+ - Evaluating respiratory burden during fire seasons
94
+ - Training exposure-response models for smoke-related respiratory outcomes
95
+
96
+ ## Limitations
97
+
98
+ - **Synthetic data**: Not from air quality monitoring networks or clinical records.
99
+ - **Simplified fire model**: Fire proximity and PM2.5 modeled independently.
100
+ - **No spatial geocoding**: Scenarios proxy geography, not precise coordinates.
101
+ - **Mask efficacy**: Modeled as binary; real-world compliance varies.
