Agroforestry into its fifth decade: local responses to global challenges and goals in the Anthropocene

Chapter 1 outlined the evolution of agroforestry as a concept at plot/farm, landscape and policy scales, with all three coexisting in the current links between praxis, knowledge and policy. Chapter 19 ended with the need for policies that seek and support SDG synergy in pursuit of landscapes that not only produce goods for existing markets, but also provide the services that ‘downstream’ stakeholders have in the past taken for granted but do miss when they are affected.

Methods in agroforestry research across its three paradigms

Methods, subject to scrutiny of underlying assumptions and sources of bias, define the scientific approach to knowledge more than any other aspect, but they are driven by questions and judged by the results (data) they generate and the implications these are considered to have. Agroforestry research methods are ‘horses for courses’; there is no single method that stands out across all purposes of research. Similarly, there are no research methods that are unique to agroforestry, and few that are completely new rather than modifications of something used earlier.
