In the humid tropics, traditional agriculture is based on natural resource management, and agricultural ideology reflects a concern for managing natural processes. Natural processes are valuable resources. Natural resource management is not an activity separable from how people make a living. While natural resource management is generally taken to mean the focused management of particular naturally occurring useful items such as wild game, water, soil, minerals, and timber producing trees, tropical peoples focus on processes not items; items are seen to be the result of processes. Agricultural structures, agricultural 'scripts', and the agricultural knowledge of individuals reflect an ideological stance that natural processes are agricultural resources.
