- Farm scale and landscape diversity can affect the capacity for producers to implement agroecological systems. Small to mid-sized farms can more effectively integrate agroecological methods such as increasing landscape diversity, on-farm diversity and intercrops  . Barriers to adopting agroecological practices for small to mid-sized farms include limited market options, subsidy and policy disincentives, lack of extension support, knowledge and insecure land tenure . - Barriers for large farms to transition to agroecological practices include knowledge gaps, cost, significant infrastructure and farm design changes, labour, psycho-social adjustments, policy disincentives and market lock-ins . - Some policies and initiatives support large-sized farms to transition to agroecology . :unselected:
