Historical legacies of swidden agriculture • ancient & pervasive – throughout much of tropics • example of co-evolution of natural & social systems • major influence on contemporary biodiversity, species composition, distribution, structure and on ecosystem functions & processes • increases landscape heterogeneity & proportion early successional vegetation • integral systems are rich source of TEKP for developing productive & sustainable agricultural practices successional vegetation mosaic, Sulawesi Maya landscape, Belize
Discussion topics and questions: 1) Sustainability (ecological) a) what constrains agricultural production in the tropics? b) how do swidden systems sustain crop yields? c) how do swidden practices vary under different soil and climatic conditions? d) in recent decades long fallow swidden systems have changed/broken down; what effect has this had on soils, flora, fauna, landscapes and ecosystems functions? 2) Relationship to biodiversity a) what direct and indirect effects do integral and incipient swidden systems have on flora & fauna? b) what has been the effect of eliminating/curtailing historic swidden practices on biodiversity?
