Syllabus / Curriculum design
The module will cover the following topics: Environmental impacts of organic and conventional agriculture; conflicts between production and sustainability; maintenance, enhancement and creation of agricultural habitats and features; importance of landscape processors and historial context for agricultural systems; farm waste management planning; resource use, conservation and pollution (key issues, impacts of organic agriculture, potential and techniques for improvement); biodiversity (genetic, species and habitat level); practical whole-farm conservation planning; measuring the environmental impacts of various types of agricultural production systems and practices. Whole farm conservation plans will be prepared as group projects.
On completion of the module students should be able to:
(i) identify potential environmental impacts of particular production systems and practices;
(ii) apply ecological principles such as diversity, mutualism and density dependence to enhance the environmental impacts of
(iii) recognise the importance of landscape scale processors and historical context for agricultural systems;
(iv) outline the conflicts which occur when trying to balance production with sustainability;
(v) analyse impact on the environment at farm level;
(vi) set up a nature-conservation plan on a farm level;
(vii) set up a farm waste management plan
Aims of the module
To provide students with an understanding of the positive and negative environmental impacts of organic farming systems, and an understanding of how to use ecological principles to enhance these environmental impacts.
