Tree and palm diversity in homegardens in the Central Amazon

摘要: In the recent decades, many studies have shown important role of agroforestry, and particularly homegardens, in food supply, but few conducted Amazon include regional coverage and/or a large number samples. This makes more thorough assessment importance these agroecosystems agrobiodiversity conservation difficult. The objective present study is to assess factors that determine floristic composition tree palm diversity homegardens at different spatial scales Central Amazon. 334 were sampled rural urban areas 14 municipalities state Para. Owners interviewed for collection socioeconomic data. A total 16,049 individual recorded, distributed 108 species. Most species fruit bearing. correlations between environmental gradient established each ordination significant only local scale. Species richness was influenced by related family income, homegarden size, topographic environment. criteria selecting comprised are aimed security families own homegardens. Thus, strongly owners’ decisions level than broader scales. autonomy indicate public policies should be designed stimulate diverse production systems as strategy strengthen agriculture
