Best Climate for Farming in the World: Yield and Water

No single climate wins. The best climate for farming in the world is a mild, mid-latitude one with rain through the growing season, a long frost-free period and deep, dark soil. Farmers in hot and dry places can still match it, but only if they bring water. In 2024 the United States averaged 8,414 kg of cereal per harvested hectare, and Egypt, a hot desert country with irrigation, averaged 7,360 kg (World Bank, from FAO data).

This guide ranks what makes a climate good for crops, shows yield and water data for ten countries, and then gives seven practical ways to farm well when the weather is hot. It also has a pumping calculator to test your own water and energy needs.

What makes a climate good for farming

Four things matter most: temperature, water, season length and soil. A climate scores well when all four line up for the crop you grow. It scores badly when one of them fails, even if the others are perfect.

• Temperature: warm enough for growth, but not so hot that flowers and grain fail. Many field crops lose yield once days pass about 30°C (86°F), as shown below.
• Water: rain that arrives when the crop needs it, or irrigation to fill the gap.
• Season length: enough frost-free days for the crop to finish.
• Soil: deep, with plenty of organic matter and few salts.

Hot desert is the most common climate type on land. A global climate map by Peel and colleagues puts hot desert (BWh) at 14.2% of land area, ahead of tropical savannah (Aw) at 11.5% (Hydrology and Earth System Sciences, 2007). So the question for most farmers is not how to find the perfect climate. It is how to work with the one they have.

The best soils sit in temperate grassland climates

Some of the most fertile soils form under grassland in middle latitudes. Mollisols are soft, dark grassland soils. They cover about 7% of the world’s ice-free land and occur mainly in middle latitudes such as the US Great Plains (University of Idaho, citing USDA-NRCS). In the United States they are the largest soil order, at about 21.5% of land area. A University of Nebraska teaching table gives the same world share of 7% (UNL PASSEL).

This is one reason the US corn belt, parts of southern Canada and the grain lands of Europe do so well. Good soil, moderate temperature and rain in summer come together.

Cereal yields by country show climate and water together

Yield per hectare is a fair first test of how well a place grows crops. The World Bank publishes cereal yield by country from FAO data. It counts wheat, rice, maize, barley, oats, rye, millet, sorghum and other cereals harvested for dry grain, measured per hectare harvested. Crop mix differs by country, so read it as a guide, not a league table.

In 2024 the United States led the eight countries on the chart, followed by Egypt, the Netherlands and France. Egypt is hot and has little rain, yet it ranks second. Irrigation is one likely reason, though inputs and soils also play a part. The Dutch figure fell from 8,080 kg in 2023 to 6,806 kg in 2024, a one-year move, so read single years with care. Canada’s short season and Australia’s dry, variable rain are likely reasons for their lower averages.

How heat hurts crops

High temperature does damage at flowering and grain fill. A 2017 study in Nature Communications compared nine crop models with US county data. It found that each day above 30°C reduces rainfed maize and soybean yield by up to 6%. The loss was weak where fields were irrigated, which supports the view that water stress is the cause (Schauberger et al., Nature Communications, 2017). Heat and water problems arrive together.

Fruit crops are sensitive too. In a growth-chamber trial, raising tomato day and night temperatures from 28/22°C to 32/26°C reduced fruit set. The cause was less pollen release and weaker pollen, not less pollen made (Annals of Botany via PubMed Central). In short, warm nights matter as well as hot days.

Why yields swing more in dry climates

Rain is the main swing factor for farms without irrigation. The chart shows Australia rising from 1,961 kg in 2000 to 3,278 kg in 2022 before falling to 2,690 kg in 2024, while France stayed between about 6,300 and 7,600 kg in the years shown and Egypt between about 6,500 and 7,500 kg. Egypt’s yield changed less than rainfed countries, which fits its reliance on managed irrigation rather than rain, though it is not proof.

Water is the bigger lever in hot climates

Agriculture accounts for about 69% of global water withdrawals, ahead of industry (19%) and municipal use (12%), according to FAO AQUASTAT. The FAO drought portal adds that in arid and semi-arid countries farming is often confined to irrigated land (FAO drought portal). The World Bank country data show the spread: farming takes 82% of freshwater withdrawals in Saudi Arabia and 79% in Egypt, but 3% in the Netherlands.

Irrigation also brings a risk. A FAO global map of salt-affected soils found more than 424 million hectares of topsoil and 833 million hectares of subsoil affected by salt, with more than two thirds in arid and semi-arid zones (FAO via UNCCD, 2021). Hot, dry fields lose water by evaporation and leave salt behind, so drainage and salt checks belong in every hot-climate plan.

7 ways to farm well in hot climates

These steps do not change the climate. They narrow the gap between a hot place and a mild one. Local advice from your extension office comes first, and any chemical use must follow the product label and local rules.

▶ Seven simple ways to protect soil and water, explained in plain English. · 4:34

1. Pick crops and varieties for your heat and water

Start from the heat limits above. Maize and soybean lose yield in hot rainfed seasons, and tomato sets less fruit in warm nights. Ask your local seed supplier or extension service for varieties tested in your area, and plant so that flowering avoids the hottest weeks where the calendar allows it.

2. Mulch the soil

Mulched soil takes in water better and loses less to evaporation because the soil stays cooler, says University of Georgia Extension (UGA Extension C984). Choice of mulch matters. A University of Wisconsin-Extension guide notes that clear plastic warms soil the most, by an average of about 9°F over bare soil, so organic mulches suit hot weather better (UW-Extension).

3. Use drip or low-pressure irrigation and schedule it

The method sets how much water reaches the roots. Alberta Agriculture lists design efficiencies of 88% for micro drip, 84% for low-pressure pivots and 65% for stationary volume guns (Alberta Agriculture, irrigation efficiency table). The same table gives ranges, for example 70 to 95% for drip, so management matters as much as hardware. Schedule by soil moisture readings, not by the calendar.

4. Manage soil health and salt

Add organic matter such as compost to raise the soil’s capacity to hold water. Test irrigation water and soil for salt each season. If salts build up, you may need extra water for leaching and good drainage. Ask a local agronomist for the target in your soil.

5. Use integrated pest and disease management

Heat and humidity favour some diseases, tomato rot among them. Combine crop rotation, removing infected debris, resistant varieties, drip irrigation that keeps leaves dry, and fungicide only when needed. Follow the product label and local rules for any spray, and rotate active ingredients to slow resistance.

6. Choose and size the pump for the job

Pumping uses real energy. Lifting one cubic metre of water by one metre takes about 0.00272 kWh at 100% efficiency, a physical constant. So the deeper the water and the lower the pump efficiency, the larger the bill. Submersible pumps suit deep wells, and centrifugal pumps suit surface water. A solar-powered pump can cut grid use where the sun is strong, but check the quote for your head and flow. The calculator below turns your numbers into water volume and energy cost.

7. Watch the crop from above

Satellite vegetation maps show where a crop is greener or weaker, and they help you decide where to walk the field first. They show change in plant cover, not its cause, so follow up on the ground. Farmonaut Satellite + AI Farm Monitoring System is one such tool for farm owners.

How to read your own climate before you plant

A country average hides a lot. Two farms in the same state can have different frost dates, rainfall and soil. Use this short routine to judge a field, whatever the continent.

1. Get ten years of weather. Ask your national weather service or university extension office for daily rain and temperature records near your farm. A single dry or wet year can mislead you.
2. Count the hot days. Note how many days pass 30°C in the weeks when your crop flowers. Those weeks matter more than the seasonal mean.
3. Check the rain pattern. Total rain is less useful than when it falls. A wet winter followed by a dry summer needs stored soil water or irrigation.
4. Find your frost dates. The last spring frost and first autumn frost set the length of your season and the maturity group you can use.
5. Test the soil. Ask a lab for organic matter, pH and salt readings. A good climate cannot rescue a salty or shallow soil.
6. Match the crop. Pick a crop and variety whose flowering window avoids your worst heat and whose water need fits your supply.

Write the results down for each field. After two or three seasons you will see which fields lose first in a hot, dry year, and you can plan irrigation, mulch and crop choice around them.

What the country numbers say for farmers in each region

The World Bank figures above are national averages, but they hint at what readers in each market face.

United States. The 2024 average of 8,414 kg per hectare is the highest of the eight countries on the yield chart. The country has big areas of dark grassland soil and a summer rain pattern that suits maize. Even so, the heat study cited above shows that very hot days cost yield in rainfed fields, which is why irrigation in the drier west and heat-tolerant hybrids matter.

Canada. At 4,021 kg per hectare in 2024, Canada sits well below the US. A short frost-free season is a likely limit, along with differences in crop mix. Its agriculture uses a small share of freshwater: 10.7% of withdrawals in 2022. Early-maturing varieties and good planting dates are the main tools.

France and the Netherlands. Both show how a mild maritime climate and strong farm management go with high and steady yields. Agriculture’s share of freshwater withdrawals is small in both, at 10.3% and 3.2% in 2022, because rain meets most crop needs.

Australia. Cereal yield was 2,690 kg per hectare in 2024 and swung from 1,961 kg in 2000 to 3,278 kg in 2022. Dry years and big fields on poorer soils pull the average down, and high rain variability makes planning hard. Water, soil moisture and the timing of sowing decide results.

Argentina and South Africa. Both have large grain areas in warmer climates. Argentina’s yield rose from 3,448 kg in 2000 to 5,410 kg in 2021, then fell to 3,993 kg in 2023 before recovering to 4,854 kg in 2024. Swings like these show how single seasons can move a national average.

Common mistakes in hot-climate farming

These errors show up again and again on hot farms. Each one is cheap to fix.

• Watering by habit. Fixed calendar watering wastes water in cool spells and falls short in heat waves. Use soil moisture and weather data to adjust.
• Ignoring salt. Salt builds up slowly, then yield falls in patches. Test the soil and the water each season.
• Bare soil in summer. Exposed soil heats up and loses moisture fast. Residue or mulch helps, as the Georgia and Wisconsin extension guides explain above.
• Planting heat-sensitive crops into the hottest weeks. Move sowing so that flowering falls in a cooler window where you can.
• Oversized or mismatched pumps. A pump that runs far from its best operating point wastes energy. Get the head and flow checked by a supplier before you buy.
• Treating satellite maps as a diagnosis. A weak patch can come from water, pests, soil or planting. Walk the field before you act.

Climate change and the best places to farm

Climate is not fixed. Hot days can become more common in a farming region over time, and the US study above shows what each extra hot day can cost a rainfed crop. A farm that was comfortable in the past may need a new irrigation plan, different varieties or a new sowing date. A plan you review each season, with your own records, will serve you better than a rule you set once. For the global picture of how land is classed, the Peel climate map above is a useful reference, and your national weather service will have local trend data.

The same logic applies on good land. The mild-climate yield leaders in the chart still lose some yield in hot, dry seasons if they rely on rain. Water supply, soil care and variety choice stay important everywhere.

Tomato rot in hot weather

Tomato rot is a loose name for several diseases that soften and darken fruit or tissue. Late blight and early blight (Phytophthora and Alternaria), grey mould (Botrytis) and bacterial canker all appear in warm, wet spells. Large swings between wet and dry soil also split fruit and let infection in.

Steps that help in hot weather:

• Rotate tomatoes with crops outside the tomato family, such as potato and pepper relatives.
• Remove plant debris after harvest.
• Mulch to keep soil splash off leaves and keep soil moisture even.
• Water at the base of the plant and avoid wetting leaves.
• Use resistant varieties and check them with your local extension office.
• Spray only when needed, and follow the product label and local rules.

Why do these gaps matter for a grower? Because they show what you can control. Soil care, water supply and variety choice are in your hands, while the climate zone is not. A farm in a hot zone that fixes water and soil can come close to farms in mild zones, and a farm in a mild zone that ignores them can fall behind.

The table sums up the main trade-offs. It is a guide, not a forecast, and every cell depends on local soil and management.

Using satellite data in a hot climate

Satellite images cover a whole farm, so one person can check many fields from a desk. Vegetation index maps show where growth lags. Weather and soil data can be pulled into your own tools through an API. They cannot show the cause of stress on their own, so pair them with soil probes and field scouting.

Record keeping matters too. Heat and water data per field help you plan the next season and support a request for insurance or a loan. Ask your lender or insurer what data they accept.

How we checked the numbers

Yield and water-use figures come from the World Bank’s country indicators for cereal yield and for agricultural freshwater withdrawals, which draw on FAO data. The charts show selected countries, not a full ranking. Heat effects come from peer-reviewed work, and efficiency values from Alberta Agriculture’s table. Prices and energy tariffs are not quoted because they change; use your own.

FAQ

What is the best climate for farming in the world?

No single climate is best. Mild, mid-latitude climates with rain in the growing season and dark grassland soils give the highest yields, as in the US, France and the Netherlands. Hot and dry places can come close with irrigation: Egypt reached 7,360 kg per hectare in 2024 against 8,414 kg for the US.

Which climate zone is best for agriculture?

Temperate zones with moderate temperature, even rain and fertile soils give high yields for many field crops, such as the cereals in the chart. Tropical zones suit year-round growing but need good water and disease management.

Can you farm in a hot climate?

Yes. Egypt averaged 7,360 kg of cereal per hectare in 2024 (World Bank), a country where crops are largely irrigated. Heat still lowers yield in rainfed crops, so water, mulch and variety choice carry most of the work.

What temperature is too hot for crops?

It depends on the crop and growth stage. In US data, days above 30°C cut rainfed maize and soybean yield by up to 6% per day, and warm nights reduce tomato fruit set.

How do I find out my local climate zone for crops?

Ask your national weather service or university extension office for climate normals and the average frost dates for your county or region, then match them to your crop’s needs.
