Instrumental and Sensory Analyses of Salami from Autochthonous and Conventional Pig Breeds

Typical salami produced from Mora Romagnola (MR), an autochthonous pig breed extensively farmed within a geographically confined Italian area, are food products of commercial interest. This investigation aimed to highlight elements for the recognition and authentication of such typical salami. Five MR salami were analyzed using a sensory and instrumental approach, and the results were compared with those from eight salami made from a conventional pig breed. The sensory profiles were defined through attributes such as seasoning, pepper, garlic, fermented etc.; no differences in the products ascribable to the pig breed were highlighted. By analyzing volatile compounds, 33 molecules were detected; significant differences were found among samples, probably related to processing methods. Color differences between MR and conventional salami were identified by an electronic eye. According to instrumental texture analysis, large variability among the MR samples was detected, probably related to different types of salami (recipe, casing, size, ripening). Correlations were found among the sensory results, volatile compounds, and textural properties of the samples. Most differences do not appear to be specifically related to MR breed; only red color intensity evaluated by an electronic eye showed a correlation with breed, i.e., MR salami. This study highlights the large variability among the salami analyzed.

Food system resilience thinking: from digital to integral

The current food system is directly influenced by the increase in environmental problems and nutritional inequality globally. Financial and political collapses, health crises, excessive urbanization, and rapid industrialization are some of the principal factors threatening the food supply's security. The food system needs a profound transformation to avoid ecosystem destabilization and a global food crisis. Concerning this transformation, we are certain that the first step for a successful food system change is global resilience thinking. To reach an integrated food system, we proposed introducing the resilient concept linked with other known concepts, such as circular economy and sustainability. A resilient food system can recover over time, ensuring the supply of sustainable and quality food and access to all. This would mean redesigning the value chains in the food system, re-educating consumers to implement a healthier diet, and introducing technology such as digital innovation. Re-evaluating these relevant points, redesigning the focus of the food system, not only for economic efficiency but also including significant trade-offs, or valuing other services in the food system, are essential to reaching the desired resilience. © 2021 Society of Chemical Industry.

Which diet has the lower water footprint in Mediterranean countries?

The Mediterranean region is increasingly water scarce, with the food system being the largest driver of water use. We calculate the water resources related to food consumption in nine major Mediterranean countries, by means of the water footprint (WF), for the existing situation (period 2011-2013) as well as the Mediterranean and EAT-Lancet diets. We account for different food intake requirements according to gender and six age groups. These nine countries - Spain, France, Italy, Greece, Turkey, Egypt, Tunisia, Algeria and Morocco - represent 88% of the population of all countries bordering the Mediterranean. As first major observation, we find that the EAT-Lancet diet, a scientifically optimised diet for both nutrition and certain environmental indicators, requires less water resources than the Mediterranean diet, a culturally accepted diet within the region. In terms of water resources use, adherence to the former is thus more beneficial than adherence to the latter. As second major observation, we find that the EAT-Lancet diet reduces the current WF for all nations consistently, within the range -17% to -48%, whereas the Mediterranean diet reduces the WF of the European countries, Turkey, Egypt and Morocco within the range of -4% to -35%. For the Maghreb countries Tunisia and Algeria, the Mediterranean diet WF is slightly higher compared to the current WF and the proportions of food product groups differ. Such dietary shifts would be important parts of the solution to obtain the sustainable use of water resources in Mediterranean countries.

A rapid assessment framework for food system shocks: Lessons learned from COVID-19 in the Indo-Pacific region

The frequency and severity of shocks to food systems is accelerating globally, exemplified by the current COVID-19 outbreak. In low- and middle-income countries, the impacts have exacerbated existing food system vulnerabilities and poverty. Governments and donors must respond quickly, but few tools are available that identify interventions to build food system resilience, or emerging opportunities for transformation. In this paper we reflect on the application of a systems-based rapid assessment which we applied across 11 Indo-Pacific countries in May-July 2020. Our approach was shaped by three design parameters: the integration of key informants' perspectives engaged remotely within the countries, applicability to diverse food systems and COVID-19 experiences across the region, and the consideration of food systems as complex systems. For the rapid assessment we adopted an analytical framework proposed by Allen and Prosperi (2016). To include a development lens, we added the analysis of vulnerable groups and their exposure, impacts, recovery potential and resilience, and pro-poor interventions. We concluded that the framework and approach facilitated integration and triangulation of disparate knowledge types and data to identify priority interventions and was sufficiently flexible to be applied across food systems, at both national, sub-national and commodity scales. The step-wise method was simple and enabled structured inquiry and reporting. Although the systems concepts appeared more easily transferrable to key informants in some countries than others, potentially transformational interventions were identified, and also some risks of maladaptation. We present a refined framework that emphasises analysis of political, economic and institutional drivers of exposure and vulnerability, the constraints that they pose for building recovery potential and resilience, and trade-offs amongst winners and losers inherent in proposed interventions.

Assessing Community Contributions to Sustainable Food Systems: Dietitians Leverage Practice, Process and Paradigms

Food systems are not sustainable, and efforts to address this are paralyzed by the complex networks of food system actors and factors that interact across sectoral and geographic scales. Actions at the community level can positively contribute toward globally sustainable food systems (SFS). Assessing such contributions has two central challenges: 1) a lack of methods that support alignment between communities and across scales, balanced against the need to involve the community in developing relevant indicators; and 2) the absence of adequate, fine grained data relevant to the community. Addressing these two challenges, this paper illustrates a proposed procedure that supports community engagement with, and assessment of, their contributions. Engaged by a community of Canadian dietitians, researchers used the Delphi Inquiry method, guided by the Framework for Strategic Sustainable Development, to address the first challenge, and causal loop diagrams informed by the Cultural Adaptation Template to address the second. Indicators were developed for dietitian-identified actions and outcomes for SFS. Modeling indicator interactions provide insight into how some actions are influenced by and reinforce the value placed on SFS within the professional cultural paradigm, as well as priority areas for action and measurement. Process-oriented assessment is useful in the context of partial and subjective understandings of a dynamic system, and supports continual adjustment in action. This article offers theoretical and practical insight for community engagement in addressing some of the systemic challenges in food systems. It accommodates community-based knowledge, applies process-indicators, and emphasizes the importance of cultural paradigms as a driving force of community-level actions, and overall system change. Under current conditions, facilitating SFS literacy among dietitians can amplify adaptations for broader SFS development.

Metrics to analyze and improve diets through food Systems in low and Middle Income Countries

Taking a food systems approach is a promising strategy for improving diets. Implementing such an approach would require the use of a comprehensive set of metrics to characterize food systems, set meaningful goals, track food system performance, and evaluate the impacts of food system interventions. Food system metrics are also useful to structure debates and communicate to policy makers and the general public. This paper provides an updated analytical framework of food systems and uses this to identify systematically relevant metrics and indicators based on data availability in low and middle income countries. We conclude that public data are relatively well available for food system drivers and outcomes, but not for all of the food system activities. With only minor additional investments, existing surveys could be extended to cover a large part of the required additional data. For some indicators, however, targeted data collection efforts are needed. As the list of indicators partly overlaps with the indicators for the Sustainable Development Goals (SGDs), part of the collected data could serve not only to describe and monitor food systems, but also to track progress towards attaining the SDGs.

An Analytical Framework for Assessing Context-Specific Rural Livelihood Vulnerability

Reviewing both conceptual and empirical studies on climate vulnerability and adaptation assessment, this paper offers an analytical framework to help better understand how context-specific adaptation strategies could be developed. The framework systematically assembles the Sustainable Rural Livelihoods and the Vulnerability Assessment frameworks to develop its structural and analytical components. The resulting five-step approach involves: (i) identification of context along with understanding what aspect of vulnerability need to be studied; (ii) assessment of livelihood exposure to climate impacts involving both community perspectives and meteorological data-based climate forecasts; (iii) characterization of available capital asset usages to help buffer climate sensitivity; (iv) analysis of formal and informal institutional impetus to enhance adaptive capacity; and (v) evaluation of gaps between context-specific vulnerability and institutional and policy responses to avoid maladaptive trajectories. Drawing on published research and policy documentation, we apply the framework to the livelihood systems operating in the northeastern floodplain community of Bangladesh to demonstrate the utility of the approach and then discuss its potential to inform adaptation strategies.

Assessing Sustainability Performance at the Farm Level: Examples from Greek Agricultural Systems

In recent years, farmers and policymakers have faced ample challenges and have struggled to support the sustainability of the agricultural sector. Sustainable agriculture encompasses multiple concepts, and its performance produces extensive debate about data requirements, appropriate indicators, evaluation methods, and tools. Under the European Union (EU) financed project FLINT (Farm Level Indicators for New Topics in policy evaluation), detailed data have been collected at the farm level to provide broader coverage of sustainability indicators on a wide range of relevant topics to facilitate the assessment of sustainability performance. The approach has been applied in a pilot network of representative farms at the EU level, considering the heterogeneity of the EU farming sector to provide data infrastructure with up to date information for sustainability indicators. This study aims to assess sustainability performance at the farm level in Greece. Representative and dominant agricultural systems, such as permanent crops, olive trees, arable crops, and livestock (sheep) farms, comprise the Greek sample. It uses the analytical hierarchy process (AHP) methodology and attempts to gain insights into the sustainability performance of agricultural systems. The outcome of the sustainability assessment reveals knowledge and develops support for strategic farm choices in order to support both farmers and policymakers towards more sustainable development plans. The results indicate that three typical Mediterranean farming systems, namely permanent crops, olive trees, and extensive livestock systems (sheep farms), are more sustainable in contrast to intensive and arable crop farms.

Food Security: Microbiological and Chemical Risks

Food Security within a health security context relates to systems dealing with the prevention and control of not only acute but also sporadic and chronic foodborne diseases. The description of food security and safety systems in this chapter will hence include oversight of both microbiological and chemical hazards, which both can cause acute as well as chronic disease events.

The Chapter includes a description of existing national and international surveillance systems for foodborne diseases and regulatory systems enabling risk mitigation action for both chemical and microbiological hazards, with specific inclusion of the concerning increase in antimicrobial resistance (AMR) of foodborne microorganisms also related to the animal production systems.

The Chapter also includes descriptions of methodology for the quantitative assessment of sustainability of food production systems.

Modeling Sustainable Food Systems

The processes underlying environmental, economic, and social unsustainability derive in part from the food system. Building sustainable food systems has become a predominating endeavor aiming to redirect our food systems and policies towards better-adjusted goals and improved societal welfare. Food systems are complex social-ecological systems involving multiple interactions between human and natural components. Policy needs to encourage public perception of humanity and nature as interdependent and interacting. The systemic nature of these interdependencies and interactions calls for systems approaches and integrated assessment tools. Identifying and modeling the intrinsic properties of the food system that will ensure its essential outcomes are maintained or enhanced over time and across generations, will help organizations and governmental institutions to track progress towards sustainability, and set policies that encourage positive transformations. This paper proposes a conceptual model that articulates crucial vulnerability and resilience factors to global environmental and socio-economic changes, postulating specific food and nutrition security issues as priority outcomes of food systems. By acknowledging the systemic nature of sustainability, this approach allows consideration of causal factor dynamics. In a stepwise approach, a logical application is schematized for three Mediterranean countries, namely Spain, France, and Italy.
