Agricultural expansion

Agricultural expansion describes the growth of agricultural land such as arable land and pastures, especially in the 20th and 21st centuries. This increase in farming land is mainly driven by the need to feed and provide energy for a growing global population, which is expected to reach 10 billion people by the end of this century.

As agriculture expands, many natural environments, both terrestrial and aquatic, are affected adversely. This includes habitat loss, land degradation, and overexploitation. The push for more food and biofuel production, especially in tropical regions, continues to threaten these ecosystems.

Modern agriculture often uses intensive methods, focusing on a few highly productive crops. This has already caused a significant loss of biodiversity worldwide. Agricultural expansion is also the main reason for deforestation and forest fragmentation, with large-scale farming like cattle ranching and growing oil palm playing major roles.

The FAO predicts that the use of arable land will keep growing, especially in developing countries, while it may decline in developed countries. Examples of agricultural expansion include the spread of palm oil production and land conversion for soy bean farming in South America. These changes highlight the urgent need for more sustainable farming practices.
