The document discusses results chains, which are tools that clarify how project strategies are believed to contribute to achieving social or biodiversity targets. A results chain maps out a series of causal statements linking factors in an "if...then" fashion, demonstrating the desired future condition with the project. It should have boxes containing desired results rather than activities, with clear causal links between boxes showing hoped-for changes over time from strategies to impacts. Criteria for a good results chain include being simple, results-oriented, causally linked, demonstrating change, and reasonably complete.
