Integrated farming with intercropping increases food production while reducing environmental footprint

Area of Science:

• Agricultural Science
• Environmental Science
• Sustainable Agriculture

Background:

• Food security is a major challenge for smallholder farms in populated regions.
• Industrialized agriculture increases food supply but causes environmental damage through synthetic inputs.
• Sustainable farming methods are crucial for increasing food production with a reduced environmental footprint.

Purpose of the Study:

• To develop and evaluate an integrated cropping system for smallholder farms.
• To assess the system's impact on crop yield, farm profitability, and environmental footprint.
• To provide a sustainable alternative to traditional monoculture farming.

Main Methods:

• Implemented an integrated cropping system combining intensified cropping (relay/intercropping), strip rotation, soil mulching, and reduced tillage.
• Conducted sixteen field experiments over 12 years (2006-2017) with diverse crop inputs.
• Compared the integrated system against traditional monoculture cropping practices.

Main Results:

• The integrated system, particularly with intercropping, demonstrated significant synergies.
• Annual crop yields increased by 15.6% to 49.9%.
• Farm net returns rose by 39.2%, and the environmental footprint decreased by 17.3%.

Conclusions:

• Integrated farming systems offer a dual benefit of increased food production and reduced environmental impact.
• Smallholder farmers can enhance both food security and environmental sustainability through adoption.
• The study validates the effectiveness of combining multiple sustainable practices in cropping systems.
