CDAE 002 Lecture Notes - Lecture 18: Plant Breeding, Food Security, Social Inequality
Document Summary
Intensi cation = producing more food on the same amount of land already under production. Extensi cation = producing more food by bringing new land under cultivation. Is it more sustainable environmentally to intensify as opposed to extensify: generally yes, extensi cation can lead to . Core features of si production systems: utilize crop varieties and breeds with high ratio of productivity to inputs. Want more yield using less inputs: avoid unnecessary use of external inputs. Target communities in context of where they are currently at: minimize impacts of system management on externalities such as ghg emissions, clean water, carbon sequestration, biodiversity, etc. How we address climate change: pragmatic (not ideological) approach drawing upon ideas from biotechnology, conventional farming, agroecology, and organic farming. Example: integrated pest management: the development of a variety of methods or pest control designed to complement, reduce, or replace the application of synthetic pesticides, wholistic approach to control pests.
