What are arable crops?

- grain crops cultivated for their edible starch grains (wheat, maize, rice, barley, millet);
- pulse crops of the legume family grown for their edible seeds which are high in protein (lentil, beans, peas);
- oil seed crops grown for oil extraction from their seeds (rapeseed, soybean, sunflower);
- forage crops used for feeding animals, fresh or preserved (cowpea, clovers, timothy);
- fibre crops cultivated for non-food use (cotton, jute, flax);
- tuber crops grown for their edible underground parts (potato, elephant yam).

Arable farming dates back to the very first agricultural communities. As well as giving us many of our staple foods, it is also responsible for producing oils and fodder for animals (Figure 2) [3].

Arable farming produces a wide range of annual crops. ‘Annual’ means that the whole life cycle of these crops, from germination to grain production, is complete within 12 months [4].Crop production in the EU and globally
The EU produced 309.9 million tonnes of cereals (including rice) in 2017, about 11.9 % of the global harvest. In terms of quantity produced and area of land used, wheat is by far the most popular cereal grown in the EU, making up nearly half the total area dedicated to cereal production. Of the remaining 50%, about one third is maize and one third barley. Other cereals grown in smaller quantities include triticale, rye, oats and spelt (Figure 3).

Two main root crops are grown in the EU: sugar beet and potatoes (4 million hectares). Other root crops like fodder beet, fodder kale, rutabaga, fodder carrot and turnips are specialist crops grown on a combined total of only 0.1 million hectares.The EU is the world’s leading producer of sugar beet, accounting for about half of global production. However, only 20% of the world’s sugar production comes from sugar beet, the other 80% being produced from sugar cane.Challenges in crop production
There are many challenges facing today’s arable farmers but some of the most significant are:- Feeding a growing population: For many reasons, not least the growing global population, farmers need to produce more food from the same amount of land. This requires higher yields but also less food loss pre-harvest, and better post-harvest systems for getting the food to the consumer without waste [8].
- Climate: Crop production is very sensitive to weather conditions at key times of the year, particularly days of sunshine, temperature and precipitation levels. For example, depending on a crop’s stage of development, heavy spring frosts can damage the growth of cereals and destroy fruit blossoms [4]. Likewise, summer droughts can cause crops to wither or to scorch and strong winds and heavy rain can flatten crops, making them hard to harvest [9]. Climate change is creating a longer-term challenge [10]. While many farmers are currently managing to achieve high yields, their ability to respond to weather variations has reduced in the last decades [11]. Historic data shows that temperatures are rising by 0.2°C per decade and the warming does significantly affect the yield of crops [12].
- Weed, pest and disease resistance: The extended use of chemical solutions to tackle the spread of weeds, pests and diseases has, over time, led to increased resistance, making the chemicals less effective [13].
- Soil degradation: Intensive farming practices and the use of heavy machinery are putting our soils under increasing pressure [14].

The map below (Figure 4) shows the major agricultural crops worldwide. Using this map to get you started (you may want to investigate in more detail), find out which crops are produced in your country. Is your country dependent on a specific crop type? What effects do you think this might have in terms of sustainability?
