Responding to change as a food gardening strategy.

Abstract As discussed in chapter 2, food gardening always involves working with change and uncertainty, but how to respond to that change may depend on whether it is in the form of familiar variation or long-term trends. This chapter begins with an overview and some basic concepts about responding to change, and then describe making observations, doing experiments, and organizing how to work together to respond effectively. More detailed discussion about doing formal experiments can be found in Appendix 3A.
