Parameters are calibrated from real-world programs including IBLI (Kenya/Ethiopia), WFP R4 Rural Resilience Initiative, and ACRE Africa. ## Dataset Description ### Scenarios | Scenario | Description | |---|---| | **baseline** | Current-state parameters reflecting existing IBLI/R4/ACRE enrollment and payout patterns | | **expanded_index_insurance** | 2.5× enrollment scaling via premium subsidy and mobile distribution (ACRE model) | | **climate_shock** | +15 percentage point drought probability shift reflecting IPCC AR6 projections for SSA | Each scenario contains ~10,000 records. ### Countries Kenya, Ethiopia, Tanzania, Malawi, Zambia, Zimbabwe, Mozambique, Senegal, Ghana, Nigeria, Rwanda, Uganda ### Variables | Variable | Type | Description | |---|---|---| | record_id | int | Unique identifier | | country | str | Country name | | year | int | Calendar year (2015–2024) | | season | str | Growing season (`long_rains` / `short_rains`) | | crop_type | str | `maize` / `wheat` / `sorghum` / `rice` / `cassava` | | insurance_type | str | `index_based` / `area_yield` / `weather_derivative` | | scenario | str | Policy scenario | | enrolled_hectares | float | Hectares covered (0.2–20) | | premium_paid_usd | float | Premium in USD | | ndvi_anomaly | float | NDVI z-score (negative = vegetation deficit) | | rainfall_deficit_pct | float | Percentage below normal rainfall | | yield_loss_pct | float | Estimated yield loss (0–100%) | | payout_triggered | bool | Whether index triggered a payout | | payout_amount_usd | float | Payout disbursement in USD | | payout_ratio | float | Payout as fraction of insured value | | farmer_count | int | Farmers in the micro-cohort | | enrollment_rate | float | Regional enrollment rate (0–1) | | lapse_rate | float | Policy non-renewal rate (0–1) | | basis_risk_score | float | Residual unhedged risk (0 = perfect, 1 = none) | ## Parameter Calibration Key parameters are drawn from published literature and program reports: - **Premium rates**: IBLI charges 5.5%/3.25% of insured value for upper/lower Marsabit; R4 farmers contribute 10–15% of premium in cash or labor (WFP 2019) - **Payout trigger**: IBLI indemnifies when cumulative NDVI deviation falls below the 15th percentile of historical conditions (ILRI 2013); ACRE triggers when area yield falls below 80% of historical average - **Basis risk**: Jensen et al. (2016, AJAE) find IBLI reduces covariate risk by 63% but leaves policyholders with 69% of original risk from high-loss events - **Enrollment**: R4 reached ~180,000 insured households in 2020 across 10 countries (WFP 2020); ACRE reached ~400,000 farmers by 2015 (GIIF 2016) - **Climate projections**: IPCC AR6 WGII projects increased drought frequency across the Sahel and East Africa through 2050 ## Sources 1.
