“…Thus, scholars have emphasized the need for shifts in human diets in order to improve both human and environmental health [44,45]. This claim has been taken up by governments, which seek to reduce the external costs of unsustainable diets [46][47][48]. In Switzerland, the government promotes a balanced diet and healthy lifestyle in its Swiss Nutrition Strategy 2017-2024 [34] aiming at setting better framework conditions for healthy diets, increasing knowledge and awareness among citizens, and cooperating with actors along the value chain of the agri-food system in order to make them provide healthier food and meals.…”

Abstract:A transition towards a circular economy of phosphorus (P) in Switzerland is a multi-faceted challenge as P use is subject to a variety of influencing factors comprising policy interventions, consumption trends, or technological innovations on different spatial scales. Therefore, scenarios for P use that take into account both the social and the technical dimension of change are needed for investigating possible pathways of a transition towards more sustainable P futures. Drawing on the multi-level perspective of transition theory, we develop scenarios on the landscape level, i.e., a balanced and healthy human diet, on the regime level, i.e., P recovery from sewage sludge (ash) and meat and bone meal, and on the niche level, i.e., urine separation. Based on the P system of the year 2015, we assess the quantitative implications of the scenarios for the Swiss P system. While scenario 1 mainly affects the agricultural system by reducing the overall P throughput, scenario 2 significantly changes P use in waste management, because P losses to landfills and cement plants decrease and the production of secondary P increases. Scenario 3 shows little quantitative impact on the national P system. From a qualitative transition perspective, however, urine separation entails fundamental socio-technical shifts in the wastewater system, whereas P recovery from sewage sludge (ash) represents an incremental system adaptation. The combination of flow-and transition-oriented research provides more general insights into how a circular economy of P can be reached. Furthermore, the analysis of P recycling scenarios reveals that transition processes in Switzerland are embedded in a global resource economy. Thus, a sole focus on concepts of national P self-sufficiency and the reduction of Switzerland's P import dependency tend to fall short when analysing the economisation of secondary P materials in the face of transnational resource flows and markets.

“…It is worth considering how nutrition and public policies can affect dietary patterns, lifestyles and food economics [5,6,29]. The effect of nutrition policies, especially in schools, is to shift the demand curve by providing more information on nutrition relatedhealth effects, enjoyability of foods and ease of their preparation to youth and their communities [6,29].…”

“…The recent emerging of nutrition economics discipline is crucial to increase the understanding of nutrition's impact on disease prevention [4,5] and to generate nutrition policy relevant evidence [6]. The nutrition economic analysis is used to evaluate if and how much healthy lifestyle choices will vary with 3 primary economic variables: income, food prices, and information about nutrition and health [4].…”

“…The goal of the present study was to evaluate the impact of primary prevention of stones using a strategy of increased fl uid intake, using the French healthcare system as an example. This health economic assessment of increased water intake is performed taking into consideration a recent policy paper on health economic evaluations in relation to nutrition [ 14 ] .…”

Primary prevention of nephrolithiasis is cost‐effective for a national healthcare system

et al. 2012

Study Type – Therapy (cost‐effectiveness meeting)Level of Evidence 2bWhat's known on the subject? and What does the study add?One of the major problems with nephrolithiasis is the high rate of recurrence, which can effect up to 50% of patients over a 5‐year period. Patients with recurrent stones are recommended to increase fluid intake based on prospective studies that show a reduction in recurrence rates in patients who intake a high volume of water. Strategies to reduce stones in recurrent stone formers are quite effective with a >50% risk reduction with increased fluid intake alone. Unfortunately, despite a high societal cost and morbidity, there are no prospective studies evaluating the benefit of fluid intake to prevent stone disease in subjects without a prior history of stone but at risk for stones.The budget impact analyses show that prevention of nephrolithiasis can have a significant cost savings for a payer in a healthcare system and reduce the stone burden significantly. Future studies will need to assess the feasibility and effectiveness of such an approach in a population.OBJECTIVE To evaluate the impact of primary prevention of stones using a strategy of increased fluid intake. SUBJECTS AND METHODS A Markov model was constructed and analysed using Excel to calculate and compare the costs and outcomes for a virtual cohort of subjects with low vs high water intake. A literature search was used to formulate assumptions for the model including an annual incidence of urolithiasis of 0.032%, annual risk of stone recurrence of 14.4% and 40% risk reduction in subjects with high water intake. Costs were based on resource utilisation from the Delphi panel and official price lists in France. Outcomes were based on payer perspective and included direct and indirect costs and loss of work. RESULTS The base‐case analysis found total cost of urolithiasis is €4267 with direct costs of €2767, including cost of treatment and complications. The annual budget impact for stone disease based on 65 million inhabitants is €590 million for the payer. The use of high water intake by 100% of the population results in annual cost savings of €273 million and 9265 fewer stones. Even if only 25% of the population is compliant, there is still a cost saving of €68 million and 2316 stones. The model was evaluated to determine the impact of varying the assumptions by ±10%. For example, when the incidence of stone disease is increased or decreased by 10% then the mean (range) baseline cost will change by €59 (531–649) million for the payer and savings will either increase or decrease by €27 (246–300) million. The largest impact on cost savings occurs when varying risk reduction of water by 10% resulting in either a mean (range) increase or decrease by €35 (238–308) million. Varying cost of stone management by 10% has an impact of ±€17 million. Varying other factors such as stone recurrence by 10% has only an impact of ±€9 million and varying risk of chronic kidney disease ±€1 million, as they affect only a portion of the population. CONCLUSIONS The budget impact analyses show that prevention of nephrolithiasis can have a significant cost savings for a payer in a healthcare system and reduce the stone burden significantly. Future studies will need to assess the feasibility and effectiveness of such an approach in a population.
