    Since the 1960s, research has dealt with agricultural intensification (AI) as a solution to ensure global food security. Recently, sustainable intensification (SI) has increasingly been used to describe those agricultural and farming systems that ensure adequate ecosystem service provision. Studies differ in terms of the application scales and methodologies, thus we aim to summarize the main findings from the literature on how AI and SI are assessed, from the farm to global levels.

    Net farm income for most representative farms in 2011 will be lower than in 2002. Low profit farms, which consist of 25% of the farms in the study, may not have financial resiliency to survive. The new farm bill will provide higher net farm income than a continuation of the FAIR Act. Cropland prices and cash rental rates are projected to increase slightly in all regions. Debt-to-asset ratios for most farms will increase slightly throughout the forecast period. Debt-to-asset ratios for the low-profit and small-size farms are higher than those for large and high-profit farms.
