Summary

Heterogeneity and integrative levels are other aspects of the dialectical approach. In this chapter we elaborate our fundamental argument concerning the landscape nature of biodiversity conservation, emphasizing the role of agroecosystems in evaluating the biodiversity effects of various landscape forms. The fragmentation of natural habitats leads to a heterogeneous landscape where biodiversity conservation depends on how those patches are interconnected at various spatial and temporal scales. We emphasize the ecological nature of the project (e.g., the need to preserve metapopulation structures) and the sociopolitical aspects (small farmer perspectives on nature and biodiversity). We introduce here some more advanced ecological topics such as ephemeral sources and propagating sinks, and note that the recent emphasis on novel ecosystems fits snugly within the agroecological framing of biodiversity conservation.
