How we identify marketplace sites
1. Where people live
Province totals for 2025–26 (EUAA, from the September 2025 estimate) were split across 398 districts in proportion to NSIA's district estimates, then spread within each district using Kontur's 400-meter population hexagons (145,000 cells). Each district's urban share from NSIA was assigned to its densest cells. The result is a 2025 population surface that matches official totals at province level.
2. How long it takes to reach a market
A 1-kilometer travel-cost surface was built from 283,000 OpenStreetMap road segments (October 2026), with speeds from 70 km/h on motorways to 15 km/h on tracks and 4 km/h off-road. Travel time was computed with a least-cost path algorithm from three sets of existing markets: provincial centers, cities, and WFP-monitored markets.
3. Who is underserved
Rural cells more than 60 minutes from any existing market are underserved. Cells 30 to 60 minutes away are partly served; cells within 30 minutes are served.
4. Choosing sites
Candidates are the 367 official district centers and 268 OpenStreetMap towns, excluding those within 20 km or 30 minutes of an existing market. For each province, a greedy maximal-covering search picked up to three sites, each maximizing the underserved rural population newly brought within 60 minutes. Served people count at a reduced weight, and sites must be at least 25 km apart (15 km in small provinces).
5. From people to trade
Producer households were estimated per cell using FAO DIEM's 89.2% agricultural-activity rate for rural households, adjusted for settlement density and calibrated to that national rate, with 10% for urban cells. Only part of them will use a new market. Addressable households are weighted down where an existing market is already close, and by distance within the catchment. Turnover and jobs follow from documented assumptions.
Turnover = addressable producer HH × participation × sales per HH
+ addressable rural HH × participation × US$ 270 purchases
Full formulas, parameters and limitations are in the assumptions section.
Assumptions and calculations
Core formulas
Producer HH within 60 min (gross) = Σ cells ≤60 min [ population × producer share ] ÷ 7.7
Addressable producer HH = Σ cells ≤60 min [ population × producer share × competition weight × distance decay ] ÷ 7.7
Addressable rural HH = Σ rural cells ≤60 min [ population × competition weight × distance decay ] ÷ 7.7
Producer saless = addressable producer HH × participations × sales per participating HH
Other tradings = addressable rural HH × participations × US$ 270
Total turnovers = producer saless + other tradings (s = low, base, high)
Direct jobss = 20 × sites + total turnovers ÷ 45,000 Indirect jobss = 1.6 × direct jobss
Definitions. A cell is one 400-meter population hexagon. Rural cells exclude each district's urban population (NSIA urban share, assigned to its densest cells). Competition weight: 1.0 if the cell is more than 60 minutes from an existing market, 0.5 if 30 to 60 minutes, 0.15 if within 30 minutes. Distance decay: 1.0 if the cell is within 30 minutes of the candidate site, 0.6 if 30 to 60 minutes. Addressable rural HH counts all rural households, producers or not, who could buy at the marketplace.

Deriving sales per household
Sales per participating household are built up from typical quantities sold and current unit values, so every figure can be checked and replaced with field data. All conversions use AFN 65 per US$ (WFP, October 2026).
| Component (unit value) | Livestock & cereal | Mixed farming | Irrigated horticulture | High-value tree crops |
|---|---|---|---|---|
| Small ruminants sold US$ 140 per sheep or goat | 3 head = 420 | 2 head = 280 | 1 head = 140 | 1 head = 140 |
| Dairy and livestock products qurut, butter, wool, eggs; fixed at US$ 50 | 50 | 50 | 50 | 50 |
| Wheat or other cereal surplus US$ 420 per metric ton | 0.31 t = 130 | 0.5 t = 210 | 0.31 t = 130 | 0.2 t = 84 |
| Fresh fruit and vegetables US$ 300 per metric ton (farm gate) | none | 0.7 t = 210 | 2.1 t = 630 | 0.6 t = 180 |
| Nuts, dried fruit or saffron US$ 4 per kg (farm gate) | none | none | none | 174 kg = 696 |
| Total, US$ per year | 600 | 750 | 950 | 1,150 |
- Sheep value. WFP reports livestock terms of trade of 341 kg of wheat per one-year-old female sheep (June 2024). At the October 2026 wheat price of AFN 27 per kg, that is 341 × 27 = AFN 9,207, or about US$ 140 per head.
- Wheat value. AFN 27 per kg ÷ 65 = US$ 0.42 per kg, or US$ 420 per metric ton (WFP, October 2026). Most rural households are net wheat buyers, so the marketed surplus is small.
- Fruit, vegetable and nut values. Farm-gate prices are planning assumptions set well below retail and export prices. Afghanistan exported US$ 643 million of fresh and dried fruit and nuts in 2024.
- How to read the table. Each column adds the values in its rows. For example, a livestock and cereal household selling 3 sheep (US$ 420), US$ 50 of dairy products and 0.31 metric tons of wheat (US$ 130) sells US$ 600 a year in total.
Other trading activity
A staple basket for a 7.7-person household (89 kg wheat flour, 21 kg rice, 9 kg pulses, 7 kg oil, 5 kg sugar and 1 kg salt a month) costs about AFN 5,900 a month at median WFP prices over October 2025 to October 2026 (AFN 6,050 in October 2026 alone), or about US$ 1,090 a year. Assuming a quarter of it is bought at the new marketplace gives US$ 270 per participating household.
Double counting
Site figures include everyone within 60 minutes, including people across provincial borders. Province totals take each cell once, at its best distance-decay value. National totals de-duplicate across provinces, which is why they are lower than the sum of province totals.
Limitations
- No elevation model was available, so off-road speed is flat at 4 km/h. Travel in steep terrain and winter is slower, and catchments in the highlands are likely optimistic.
- OpenStreetMap completeness varies. Unmapped tracks make some catchments too small.
- Only provincial centers, cities and WFP-monitored markets count as existing markets. Smaller district bazaars exist, so "underserved" means far from a major market.
- Kontur's 2023 layer is uneven in some provinces (Sar-e Pul notably). It is used only to distribute official totals within districts.
- Product profiles are province-level. Site-level product mix needs field confirmation.
- Security, land tenure, flood risk and community acceptance were not modeled.
