Slash-and-burn agriculture (SBA) is critical to maintaining rural peoples’ livelihoods. Yet, it causes environmental degradations that challenge its sustainability. Such are often underestimated, as they usually assessed at the local (stand) scale, overlooking larger-scale impacts. Here, we drew upon existing SBA and landscape ecology knowledge assess multiscale abiotic biotic effects of SBA. This agroecosystem involves four stages (slashing vegetation, burning farming, forest recovery) but research biased towards impacts, especially during recovery. Despite importance for key (e.g., soil fertility) species richness) attribute recovery, this stage typically too short (<10 years) compensate degradation caused by previous stages. Successional theory suggests such compensatory dynamics can promote sustainability in landscapes dominated old-growth forests. when loss exceeds certain boundaries, impacts may compromise conservation value ancient agroecosystem. We highlight should be comprehensively including landscape-scale variables percent cover) biodiversity patterns processes where practiced.

Abstract Coffee-related agricultural intensification affects bird species abundance, richness, and composition through habitat loss degradation. Production of specialty coffee is expected to be more sustainable environmentally friendly than conventional coffee. Nevertheless, not all grown sustainably. To evaluate environmental sustainability, we evaluated the assemblages in six coffee-producing communities Bolivia’s pre-montane subtropical humid forest region. do this, measured diversity, generalist specialist species, effect on assemblages, comparing plots secondary as part “Nature’s matrix”. We found significant differences abundance species. did find richness diversity Plant strata, herbaceous leaf cover, shrub cover affected Our results represent a first step toward understanding intricate relationship between biodiversity production, highlighting importance considering regional landscape characteristics – conceived Nature’s matrix when examining systems.
