The course will emphasize the practical interaction among agronomy, ecology, economics, and sociology to create an awareness of the interdisciplinary issues associated with sustainability in agriculture. Kin selection and competition in cooperative breeders. Emphasis is on using remote sensing technologies for solving applied land resource issues.
