Building Farm Resilience: The Prospects and Challenges of Organic Farming
The concept of socio-ecological resilience is applied to agricultural systems in general and to the farm level in particular. Resilience has three defining characteristics: the amount of change the system can undergo while maintaining its functions and structures, the degree of self-organization, and the capacity for learning and adaptation. To assess the resilience of a farming system, various...
متن کاملEffects of organic farming on biodiversity and ecosystem services: taking landscape complexity into account.
The recent intensification of the arable landscape by modern agriculture has had negative effects on biodiversity. Organic farming has been introduced to mitigate negative effects, but is organic farming beneficial to biodiversity? In this review, we summarize recent research on the effects of organic farming on arable biodiversity of plants, arthropods, soil biota, birds, and mammals. The ecos...
