In the near future, the global demand for food is expected to soar by 110%. However, the sustainability of our croplands and pastures is under threat due to various factors, including rising temperatures, increasing levels of greenhouse gases, and other environmental concerns.
To tackle this issue, a research team comprising members from Skoltech, the Institute of Geography of the Russian Academy of Sciences, and other esteemed research organizations has employed open data and artificial intelligence to examine the changing suitability of agricultural land over the next 25 years. Their study, titled “Climate Change Impact on Agricultural Land Suitability: An Interpretable Machine Learning-Based Eurasia Case Study,” has been published in IEEE Access.
The researchers followed a three-step methodology that involved collecting and preprocessing data, training a machine learning model, and evaluating the results. By utilizing various climate models and shared socioeconomic pathways scenarios, they predicted the distribution of croplands in Eastern Europe and Northern Asia, focusing on the impact of climate change in these regions.
By utilizing data from the European Weather Forecasting Center and climate models from different institutes worldwide, the team analyzed three different climate change scenarios. These scenarios included a sustainable, low-emission future, a “business-as-usual” trajectory with moderate emissions, and a high fossil fuel dependency scenario with significantly increased greenhouse gas emissions. The aim was to assess the irrigation conditions of arable lands globally at a resolution of 1 km x 1 km.
The study’s first author, Valery Shevchenko, highlighted the open nature of the data used, such as ERA5 climate analysis data and CMIP models. However, they acknowledged that predictions are subject to several parameters, such as land type and soil erosion.
The findings indicate that in the next 25 years, while the overall amount of arable land may increase, its distribution will shift northward. This shift may necessitate increased irrigation in certain regions, which poses potential risks for currently exploited agricultural areas.
The researchers emphasize that their findings align with existing knowledge on climate change impact on agricultural land suitability. Furthermore, they believe that their study serves as a call to action, urging the development of strategies for a sustainable future that addresses the potential challenges predicted by their model.
In conclusion, it is imperative to monitor and adapt to the changing dynamics of agricultural land suitability. With comprehensive data analysis and machine learning techniques, scientists can provide valuable insights to inform policies and practices that ensure global food security amidst the challenges posed by climate change.
