Crop and livestock production have become spatially decoupled in existing commercial agricultural regimes throughout the world. These segregated high input production systems contribute to some of the world's most pressing sustainability challenges, including climate change, nutrient imbalances, water pollution, biodiversity decline, and increasingly precarious rural livelihoods. There is substantial evidence that by closing the loop in nutrient and energy cycles, recoupling crop and livestock systems at farm and territorial scales can help reduce the environmental externalities associated with conventional commercial farming without declines in profitability or yields. Yet such 'integrated' crop and livestock systems remain rare as a proportion of global agricultural area. Based on an interdisciplinary workshop and additional literature review, we provide a comprehensive historical and international perspective on why integrated crop and livestock systems have declined in most regions and what conditions have fostered their persistence and reemergence in others. We also identify levers for encouraging the reemergence of integrated crop and livestock systems worldwide. We conclude that a major disruption of the current regime would be needed to foster crop-livestock reintegration, including a redesign of research programs, credit systems, payments for ecosystem services, insurance programs, and food safety regulations to focus on whole farm outcomes and the creation of a circular economy. An expansion of the number of integrated crop and livestock systems field trials and demonstrations and efforts to brand integrated crop and livestock systems as a form of sustainable agriculture through the development of eco-labels could also improve adoption, but would likely be unsuccessful at encouraging wide-scale change without a more radical transformation of the research and policy landscape.

Generation of uremic toxins p-cresylsulfate (p-CS), indoxyl sulfate (IS) and indole 3-acetic acid (IAA) in hemodialysis (HD) individuals may be associated with the gut flora and recognized markers of disease progression. This study investigated the effect of synbiotic meal on uremic toxins in HD individuals. We conducted randomized singleblind and placebo-controlled intervention study with 58 HD subjects (20F/38M, 63.1 ± 10.9-old) who were randomly allocated in synbiotic group (SG, 40g of extruded sorghum plus 100mL of unfermented probiotic milk) or control group (CG, 40g of extruded corn plus 100mL of pasteurized milk), during 7-wk Metabolic markers anduremictoxins,fecalconcentration ofshortchainfattyacidandpHvalue wasdetermined. The SG group had decreased serum p-CS and IS, as well as decreased urea concentration (p < .05) compared to CG. SG showed higher fecal butyric acid and lower pH compared to baseline and SC (p < .05). In addition, serum p-CS and fecal pH were positively correlated to urea concentration in SG participants at the endpoint. The consumption of the synbiotic meal during 7-wk reduced colonic pH, and reduced serum uremic (p-CS and IS) toxins and urea in HD subjects. |
