An air conditioned and self -fulfilling prophecy in Europe

Soybean production: a climate of self -sufficiency in Europe

Today, Europe imports about 90% of its soybeans, mostly from the United States and Brazil, for animal husbandry. Although the land under soybean production in the country has increased in 12 years, from 1.2 Mha in 2004 to 5 Mha in 2016, it is reported that only 1.7% of the total area of ​​European agriculture in 2016.

However, the local soybean crop is much better. Like other legumes, it regulates nitrogen in the soil to improve the symbiotic bacteria that live in its root, which is beneficial for the future plant and reduces utilization. to nitrogen plants and their environmental impact. In addition, reducing imports reduces the cost and pollution associated with them. That’s why researchers from AgroParisTech and INRAE ​​have started to find out if the European country can become its own soybeans, and whether climate change will help, or not. , it is difficult, to this plant in Europe over the next few years.

To do so, they have developed a modeling approach that involves the combined use of agronomic and climatic data as well as machine learning algorithms. Thanks to this, they were able to produce a wide range of soybean crops from the available data, as well as different food patterns and based on forecasts of climate and future conditions.

This could be achieved with 11% of Europe’s farmland for soy

The results, published at Natural Foods, shows that European agricultural land is more suitable for soybean production than the land currently harvested. Figures show an average yield of 2 metric tons per acre under current climatic conditions, even without irrigation or fertilizer, and will increase with future climatic conditions at + 0.4 to +0.6 metric tons per acre in 2050 and 2090. Movement estimates are also shown. The most extreme places from southern Europe to northern and eastern Europe due to climate change.

With a constant demand for soybeans, the results show that soybean self-sufficiency of 50 to 100% can be achieved in Europe, under current and future increases, if 4 and 11% of the farmland is dedicated to soybeans. This would require increasing the crop land by a factor of 2 to 3, or 5 to 6, for 50% or 100% of the total self -interest. Assuming that no fertilizers are used on soybeans, this increase will reduce the use of nitrogen fertilizers by 4 to 17% in Europe.
