Foods consumed and dietary patterns are strong determinants of health status. Diet and nutrition have a key role in health promotion and maintenance during the entire lifetime, but what we choose to eat and drink greatly affects the environmental impact on ecosystems as well as monetary resources. Some studies suggest that a healthy diet with a low environmental impact is not necessarily more expensive. This paper aims to identify a healthy, greener and cheaper diet based on current consumption patterns. Dietary information was collected from 104 young adults in the last year of high school in Parma (Italy). Diet was monitored with 7-day dietary records. Subsequently, food items were decoded to obtain nutritional, economic and environmental impact data. An optimization tool based on mathematical programming (Multi-Objective Linear Programming) was used to identify sustainable diet. Three different 7-day diets were identified, based on nutrition recommendations for the healthy Italian adult population, characterized by different targets and optimizing different impacts: first the diet at the lowest cost (Minimum Cost Diet - MCD), then the Environmentally Sustainable Diet (ESD) obtained by minimizing the three environmental indicators (CO2e emissions, H2O consumption and amount of land to regenerate the resources - m(2)). Finally, the Sustainable Diet (SD) was identified by integrating environmental and economic sustainability objectives. Lastly, suggestions and recommendations for communication campaigns and other interventions to achieve sustainable diet are suggested. [ABSTRACT FROM AUTHOR]

This paper presents an integrated model for the economic and environmental assessment of the use of natural resources when new activities (i.e. biomass crops for energy production) are introduced into the farm production plan. The methodology is based on the integration of positive mathematical programming (PMP) with the AquaCrop model developed by FAO. PMP represents farmer decision processes and evaluates how farms react to the biomass-sorghum activity option at different price levels. AquaCrop evaluates the relationship between water needs and biomass production and assesses the effect of the land allocation on water requirements at regional level. The integration of these two models assists global policy evaluation at regional level as it makes it possible to identify the economic threshold for biomass crops, the change in land allocation and total water requirement. The model can help policy makers to evaluate the impacts of variations in crop profitability and market innovations on farm profitability, land use and water consumption and the sustainability of the market scenario.

Sustainability is becoming a pivotal guide for driving the governance strategies of value chains. Sustainable policy should have as its objective the perpetuation of production models over time to maintain its environmental, economic and social dimensions. Therefore, measuring the sustainability of a production system is fundamental to deepening the understanding of ongoing trends, considering the pressure exerted by agricultural policies, market dynamics and innovations introduced in the production system. The purpose of this paper is to present a holistic framework for assessing the sustainability of food quality schemes (FQS), including the role of both stakeholders within the value chain, and the territorial dimension. This paper discusses the use of dimensional indicators and proposes synthetic indexes to provide an overall picture of the evolution of sustainability of a specific production system. Particularly, the evolution of sustainability in the Parmigiano Reggiano Protected Designation of Origin (PDO) production system is evaluated over the period 2000-2018. It is assumed that its evolution is due to the effect of 20 years of innovations which have impacted on product quality, value chain performance and rural development, modifying the sustainability of the whole production system.

Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through interviews with producers and key informants, direct observation, and scientific literature research in order to assess, through the SAFA Tool Software, the level of sustainability of each agricultural system as a whole and for each sustainability dimension (political, environmental, economic, and social dimension) in a comparative way. It has emerged that producers belonging to conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture have achieved levels of sustainability that are similar to each other and very good in all four dimensions of sustainability. Meanwhile, agribusiness achieved moderate scores in the dimensions of governance and environmental integrity, and was good in the economic and social dimension. [ABSTRACT FROM AUTHOR]

Recent literature has highlighted the importance of testing the sustainability performances of supply chains. Nevertheless, this field of research is still in its early stages, in particular with reference to short food supply chains (SFSCs). This research analyzed producers' and consumers' perception of the economic, social and environmental sustainability of two SFSCs of a specific quality of cheese (Parmigiano Reggiano PDO) placed in two different contexts: the first is a rural area in the Appennino Tosco-Emiliano National Park mountains and the second is a peri-urban area in Parma surroundings, both in Italy. The case study also analyzed the carbon emissions of shopping for Parmigiano Reggiano at dairy shops. Qualitative and quantitative methodologies were employed to achieve the aims of the present study. For producers in both areas, the SFSC is a successful strategy to sell a part of their output in their own outlets, gain reputation, reduce costs and at the same time increase their levels of self-esteem. Product quality is the biggest factor attracting consumers to the outlet; moreover, it is associated with trust in the producers and the idea of combining "leisure with pleasure". However, the environmental impact of the consumers' purchase activities is a drawback. [ABSTRACT FROM AUTHOR]

To identify whether EU certified food – here organic and geographical indications – is more sustainable than a conventional reference, we developed 25 indicators covering the three sustainability pillars. Original data was collected on 52 products at farm, processing and retail levels, allowing the estimation of circa 2000 indicator values. Most strikingly, we show that, in our sample, certified food outperforms its non-certified reference on most economic and social indicators. On major environmental indicators – carbon and water footprint – their performance is similar. Although certified food is 61% more expensive, the extra-performance per euro is similar to classical policy interventions to improve diet sustainability such as subsidies or taxes. Cumulatively, our findings legitimate the recent initiatives by standards to cover broader sustainability aspects. • 25 indicators are estimated for 52 food value chains to estimate their economic, environmental and social performance • The average performance of certified food is higher than its conventional reference on most economic and social indicators • The environmental performance of certified food is similar to its conventional reference on the most common indicators • Certified food is 61% more expensive, but its extra-performance per euro is similar to other policy interventions [ABSTRACT FROM AUTHOR]
