Arable Land Distribution: The distribution of arable land between the continents is as follows1:
- Asia accounts for 34% of the global agricultural land area.
- The Americas account for 25%.
- Africa accounts for 24%.
- Europe and Oceania each represent about 9-10% of the total.
Classification of Arable Land: Arable land is classified based on its capacity to sustain production2. This classification assesses and maps land according to its capability to support a range of crops on a sustainable basis2. The evaluation is based on the degree of limitation imposed on the land by a variety of physical factors which include erosion, soils, wetness, and climate2. Land is evaluated on the basis of the range of potential crops, productivity, ease of management, and risk of degradation2.
Making Arid Land Arable: Arid land can sometimes be made arable through various methods345:
- Irrigation: This includes micro-irrigation, which applies small amounts of water close to the plants; sprinkler systems, which spray water through nozzles; and gravity systems, where water floods the field or runs down furrows5.
- Efficient Water Use: Highly efficient drip irrigation systems can be used in greenhouses, yielding five to eight times more than surrounding fields4.
- Soil Treatment: The application of gypsum or acids can be used to remove salts from the soil6.
- Use of Salt-Tolerant Crops: Some crops can tolerate high salt levels in the soil6.
- Land Management: Practices such as irrigation scheduling may help farmers avoid over-irrigation5.
It’s important to note that the use of arable land resources requires matching water resources. As the amount of cultivated arable land increases, the demand for water resources from agriculture, specifically in arid areas with water shortages, also increases3.

If arable land did get used for a massive new town such as a new federal capital city, will it then get excluded from that classification? Is land designated as arable de-classified when the land is definitively used for some non agric purpose?
This conversation may have info that’s not public. Conversation will not be saved after this point.
Searching for: Does arable land get declassified when used for non-agricultural purposes?
Generating answers for you…
Yes, if arable land is used for non-agricultural purposes such as building a new town or a federal capital city, it would typically be reclassified and no longer considered arable12. Arable land refers to land that is currently used to grow annual or biennial crops1. Therefore, if the land use changes and it is no longer used for growing crops, it would not be classified as arable12.
However, it’s important to note that the classification can be dynamic. For instance, non-arable land can sometimes be converted into arable land through various methods such as improving soil quality or removing forests3. Conversely, arable land can become non-arable due to factors like urbanization, industrialization, or environmental degradation2. So, the classification of land as arable or non-arable can change over time depending on its use and the interventions applied to it123.

If a country was made up 90% of forests, would all that portion be classified as non arable?
Searching for: Can forest land be classified as arable?
Generating answers for you…
Not necessarily. While forests are typically not classified as arable land, it’s important to note that the classification of land as arable or non-arable is not solely based on its current state, but also on its potential use12.
Arable land refers to land that is currently used to grow annual or biennial crops1. Therefore, if a forested area is not currently being used to grow crops, it would not be classified as arable12. However, if the forested land were to be cleared and used for agriculture, it could potentially be reclassified as arable12.
That said, it’s important to consider the environmental impact of converting forest land into arable land. Forests play a crucial role in maintaining biodiversity, sequestering carbon, and regulating the climate2. Therefore, any decision to convert forest land into arable land should be made with careful consideration of these factors2.
In summary, while a country made up of 90% forests would likely have a large portion of land classified as non-arable under current conditions, this does not preclude the possibility of some of that land being converted into arable land in the future12. However, such decisions should be made with careful consideration of the environmental impact2.

Searching for: percentage of arable land by continent
Searching for: yield per hectare of arable land by continent
Generating answers for you…
I’m sorry, but I couldn’t find the exact data for the percentage of arable land and yield per hectare of arable land by continent. However, I can provide some general information.
Arable Land by Continent: The distribution of arable land between continents is not uniform. Asia, for example, accounts for a significant portion of the world’s arable land, followed by the Americas and Africa1. However, these percentages can vary widely within each continent, depending on factors such as climate, soil quality, and agricultural practices1.
Yield per Hectare of Arable Land: Yield per hectare can also vary significantly between continents and even between countries within the same continent1. This can be influenced by factors such as the type of crops grown, farming methods used, and the availability of resources like water and fertilizers1.
For more specific data, you may want to refer to resources like the World Bank’s DataBank2 or the Food and Agriculture Organization’s (FAO) statistics1. These sources provide detailed data on arable land and agricultural yields for individual countries, which could be used to calculate averages for each continent. Please note that this would require some data processing and analysis.
I hope this information is helpful! If you have any other questions, feel free to ask.

Why is the cereal yield in China so much higher than the others? How does it compare with that of the USA, India, Russia and Ukraine?
Searching for: Why is the cereal yield in China higher than other countries?
Searching for: Cereal yield in USA
Searching for: Cereal yield in India
Searching for: Cereal yield in Russia
Searching for: Cereal yield in Ukraine
Generating answers for you…
China’s high cereal yield can be attributed to several factors12345:
- Improved Agricultural Practices: China has implemented a range of agricultural practices that have significantly increased crop yields. These include the use of high-yield crop varieties, efficient irrigation systems, and effective use of fertilizers3.
- Government Policies: The Chinese government has implemented policies to support agricultural development, including subsidies for farmers and investments in agricultural research and infrastructure1.
- Rice Breeding: China has developed a national molecular rice breeding network and a molecular breeding platform, leading to the development of new varieties with high yield potential and resistance to water, disease, and insects5.
- Land Use Efficiency: China has managed to achieve an impressive increase in cereal output with almost no expansion of area used for cereal production4.
Now, let’s compare China’s cereal yield with that of the USA, India, Russia, and Ukraine:
- China: The cereal yield is reported at 6320 kg per hectare.
- USA: The cereal yield was reported at 8268 kg per hectare in 20216.
- India: The cereal yield was reported at 3283 kg per hectare in 20207.
- Russia: The aggregate 2022 cereal output (winter and spring crops) is set at 146.7 million tonnes, 21 percent above the five‑year average level8.
- Ukraine: The cereal yield was reported at 5453 kg per hectare in 20219.
As you can see, while China’s cereal yield is high, it is not the highest among these countries. The USA has a higher cereal yield per hectare. Factors such as agricultural practices, government policies, climate, and technological advancements all contribute to the differences in cereal yield among these countries.

Can you tell me more about high-yield crop varieties and their impact on agriculture?
Searching for: high-yield crop varieties and their impact on agriculture
Generating answers for you…
High-yield varieties (HYVs) of crops have had a significant impact on agriculture, particularly in terms of improving productivity and reducing global hunger and poverty12. Here are some key points about HYVs and their impact:
What are High-Yield Varieties? High-yield varieties refer to types of crops that have been bred to produce more output for the same amount of input compared to other varieties32. These varieties are often used in commercial and plantation farms2. The most important HYVs can be found among wheat, corn, soybean, rice, potato, and cotton2.
Impact on Agriculture:
- Increased Productivity: HYVs have significantly increased crop yields. For example, farms that switched from local to HYV rice experienced around 35% higher yield and 76% higher profit1.
- Improved Nutrition: The use of HYVs has also been associated with improved nutrition in households. More calorie intake, more protein, and especially higher fruit and vegetable intake meant less calorie poverty for adopted households1.
- Resistance to Natural Disasters: HYVs offer better resistance against natural disasters like floods and droughts, thereby enhancing the income prospects of the farmers3.
- Role in the Green Revolution: HYVs played an important role in the Green Revolution, a period in the 1960s when agricultural productivity increased dramatically as a result of new advances2.
However, it’s important to note that while HYVs have many benefits, they also have some drawbacks. For instance, they require more water and fertilizers compared to normal varieties of crops4. They also require frequent weeding and continuous use of pesticides4. Moreover, HYVs are generally more susceptible to diseases compared to traditional varieties4.
In conclusion, while HYVs have significantly increased agricultural productivity and reduced global hunger, it’s important to use them responsibly to minimize their potential negative impacts on the environment124.

Generating answers for you…
Root crops like yam and cassava are indeed staples in many countries, including Nigeria. Here’s some information on the production of these crops in Nigeria:
- Nigeria is the world’s leading producer of yam, cassava, and sweet potato1. The country accounts for over 70% of yams produced globally1. As for cassava, Nigeria produced over 34 million tonnes of this root crop2. In 2019, 50.1 million tonnes of yam were produced in Nigeria3.
As for the relative yield for root crops in the other countries you mentioned, I’m sorry but I couldn’t find the exact data. The yield can vary significantly depending on factors such as the type of crop, farming methods used, and the availability of resources like water and fertilizers.
Regarding the mix between cereals and root crops, it’s important to note that the balance between these types of crops can vary greatly from one country to another. Factors influencing this balance include the country’s climate, soil conditions, and dietary preferences. In Africa, root and tuber crops contribute 14% to the calorie supply as compared to 51% for cereals4. In South America, roots and tubers contribute 5% and in Asia only 4% to the calorie supply4.
For more specific data, you may want to refer to resources like the World Bank’s DataBank or the Food and Agriculture Organization’s (FAO) statistics. These sources provide detailed data on agricultural yields for individual countries. Please note that this would require some data processing and analysis.
