Without inorganic fertilizers, soils of less to moderate fertility can only produce substantially reduced crop yield specially of cereals. In many parts of the world these soils are prevalent. Because of long time use soils in many places lost their vigor, vitality and productivity. In this circumstance, can organic agriculture sustainably feed the world in 2050?
Organic agriculture can contribute to feeding the world sustainably in 2050, but it may not be able to do so alone, especially in regions with less to moderate fertile soils. While organic farming can produce high-quality crops, it generally has lower yields compared to conventional agriculture, which can limit its potential to feed the world's growing population.
However, organic agriculture can improve soil fertility and biodiversity, which can help to increase crop yields over time. Organic farming methods such as crop rotation, cover cropping, and composting can help to replenish soil nutrients, improve soil structure, and reduce soil erosion. These practices can also improve the water-holding capacity of soils, making them more resilient to droughts and other extreme weather events.
Additionally, organic agriculture can help to reduce greenhouse gas emissions and mitigate climate change. Organic farming methods generally require less energy and rely on fewer external inputs such as synthetic fertilizers and pesticides, which can help to reduce greenhouse gas emissions associated with agriculture.
I think that while organic agriculture can make a significant contribution to sustainable food production, it may not be able to feed the world alone, especially in regions with less to moderate fertile soils. A combination of approaches, including organic agriculture, conventional agriculture, and agroecological practices, may be necessary to sustainably feed the world in 2050. Additionally, improving soil health and fertility through sustainable farming practices should be a key priority to increase agricultural productivity and resilience to climate change.
