Importance of this Unit to the Course
This unit interprets changes in global climate as
discussed in Block 2 in terms of changes that can be estimated for agricultural production in
various countries.
Objectives
- To extend our understanding of how plants
use water and carbon dioxide to explore the implications for global
production of agricultural crops.
- To understand which regions gain and
which regions lose in agricultural potential and what opportunities
exist for adaptation to climate change.
