Where will sugarcane grow by 2050? Climate suitability shifts

What data drives the projections?

Decade snapshots are aggregated from leading climate-model ensembles on a moderate-emissions trajectory, decadal averages 2020-2060. Crop suitability comes from a recognized global crop-suitability framework, shifted by the projected climate. Commodity prices use authoritative global commodity-price indices plus 10-year annualized volatility. Trade-flow concentration uses international trade-flow statistics for the top-5 exporter share.

What this tool gives you is direction and magnitude: where the climate is heading, which crops follow that direction, which trade flows get squeezed. It is not a forecast. It is a planning framework for the next 5-30 years.

How are suitability scores calculated?

Each zone × decade × crop combination gets a 0-100 score:

80-100 — ideal climate conditions, high yield potential.
60-80 — good fit, normal yields with standard management.
40-60 — fair, marginal yields, heat or drought stress reduces upside.
20-40 — poor, the crop survives but isn’t competitive against alternatives.
0-20 — unsuitable, the climate envelope no longer supports the crop.

Scores shift across decades as growing-degree days, heat-stress days, season length, and rainfall change. Use the heatmap to spot the trajectory: green tiles drift down (crop becoming less competitive) or up (crop expanding into a new zone). The winners/losers panel surfaces the biggest moves.

What do the three trade scenarios model?

Open trade is the baseline — free-flowing exports, volatility at 10-year norms, no shocks.

Bloc fragmentation models tariff walls between trade blocs. Importers pay 6-10 % more, exporters lose 10-15 % margin from lost market access. Volatility rises ~30 %. Input costs (fertilizer, fuel) creep up.

Export ban shock models a major exporter going offline (2022-style Black Sea closure). Prices spike most on high-concentration crops where the top-5 exporters control over 75 % of trade — sunflower, wheat, sorghum. Fertilizer N spikes 25-40 %, so net margin can fall even as crop prices rise in importing countries.

The magnitudes are conservative midpoints from past disruption events. They show you the shape of the risk, not the exact path.

Costs, access, and the investment composite

Climate suitability is necessary but not sufficient. The tool surfaces five structural zone-level scores so the “where do I plant — or buy land?” question answers honestly.

Logistics access (0-100). Distance to ports, rail density, processing infrastructure. Brazilian Cerrado scores low because it’s 1500-2000 km of poor roads to Santos. Ukrainian Black Sea Coast scores high — Odesa-Mykolaiv-Kherson ports sit at the field edge. A low logistics score typically adds 8-15% to landed cost vs port-adjacent zones.

Input cost index (0-100, higher = more expensive). Fertilizer subsidies, fuel, seed cost, labor, water. India scores low (subsidies). EU zones score high (regulation + N price). California scores very high (water + labor).

Land price index (0-100, normalized). Iowa Cornbelt and California Central Valley anchor the top (premium prices). Kazakhstan, Ukrainian Polissia, Ethiopia Highlands anchor the bottom (cheap dirt). For land funds, low score = where capital deploys at a discount.

Yield gap (0-100). Gap between current yields and biophysical potential. US Cornbelt: ~10 — mature, near ceiling, little room for capital to lift. Nigeria savanna: 80 — huge unrealized lift if you bring inputs + mechanisation. Ethiopia Highlands: 75. The “uptake” axis — large gap means the agronomic envelope hasn’t been monetized yet.

Investment access (0-100). Foreign-ownership rules + currency stability + banking depth + title clarity. US/CA/AU/NZ: 90+ (open, stable). EU: 75-90. Brazil: ~60. Ukraine: ~25 (war-suppressed). China + India: ~25-30 (foreign land ownership restricted). Tells you whether outside capital can actually deploy in this zone, regardless of how good the agronomy looks.

Investment composite (0-100) blends climate trajectory + cheap dirt + yield gap + logistics + access. Switch the map to the Investment metric to see the world coloured by this single score — top zones light up deep green, mature markets stay yellow, closed/landlocked zones stay grey. The strip under the map ranks the top five.

What this tool doesn’t model

Field-level variability. This is country-zone resolution. Soil texture, slope, drainage, microclimate, and local water-table effects can move suitability ±15-20 pts within a single zone. For field-level trajectories, register a GeoPard account and pull the same logic against your real boundaries and yield history.

Breeding and varietal innovation. Suitability assumes today’s commercial cultivars. Heat-tolerant wheat, drought-tolerant maize, late-budding wine grape selections — none of these are factored in. Expect the actual envelope for any crop to widen 5-10 pts compared to what’s shown here as breeding catches up.

Irrigation and infrastructure. Suitability is calibrated for the dominant water regime in each zone (mostly rainfed). California Central Valley and Murray-Darling Basin scores assume current irrigation access; if water allocations tighten, the real picture is worse than shown.

Policy and subsidies. Trade scenarios capture price-shock magnitudes but not government responses — emergency subsidies, export quotas, strategic stockpiling, tariff retaliation. Real shocks usually trigger policy interventions that smooth the worst spikes.

Yield vs suitability. Suitability scores reflect climate fit, not absolute yield. Two zones at suitability 70 can produce very different t/ha depending on management intensity, input costs, and operator skill. Treat the scores as directional, not bookable.

Who is this built for?

Agronomists and crop consultants building 5-10 year rotation plans for their clients.

Procurement and risk teams at ag retailers, traders, and processors who need a fast read on where exposure is shifting.

Cooperative directors planning storage, contract mix, and capital projects against changing crop mixes.

Land funds and ag-investment groups scouting where dirt is cheap, yield gaps are large, climate is improving, and foreign capital can actually deploy. The Investment map metric is designed for them — switch the map and look for deep-green dots, ignore grey ones.

Investors and analysts modeling acreage shifts, asset relocation, and supply-chain resilience.

Universities and extension services using a clean visual to teach agroclimate dynamics and trade-shock pricing.
