Abstract Background The agricultural sector both needs to reduce its impacts and adapt its food production system to cope with environmental constraints and climate changes. This special issue includes three selected papers presented at the 53rd annual Conference of the Italian Society of Agricultural Economics discussing the future of agriculture. The fil rouge linking the three papers is the issue of sustainability that nowadays influences the functioning of the food supply chain and the behavior of all actors involved in it, from producers to consumers. Findings The selected papers investigate the theme of sustainability by exploring strategies for the adoption of sustainable innovation in the food supply chain, developing a model that assesses the effect of climate changes on farm production, as well as evaluating consumer attitudes to wine attributes, including those related to “carbon footprint” and “winescape esthetic.” Conclusions The reading of these papers provides a multifaceted light on different dimensions linking future perspectives of sustainable agriculture between globalization and local market. Papers discuss issues, propose approaches, and show empirical findings that can be useful to fuel the debate about future agricultural policies and stimulate the development of research agendas.

The conventionalization of organic agriculture has been described as a process in which organic agriculture increasingly adopts the features of conventional modes of production based on industrial farming methods. The increasing supply of organic products to the large retailers is considered the main driver of conventionalization. This process has negative implications for the agrobiodiversity of organic farming systems. The present study aims to investigate and analyze the impact of retailing strategies on the agrobiodiversity of organic farms. A survey of farms located in rural areas near large urban centers (three metropolitan regions in Southern Brazil and four Italian regions) was undertaken. Data was collected through face-to-face interviews based on a semi-structured questionnaire. The analysis indicates that the farms surveyed maintained a high level of agrobiodiversity and active participation in alternative food networks. Our findings point out that there was a significant and positive correlation between the crop richness index and the share of farm sales through alternative food networks. We conclude that adopting various forms of direct sale is the key factor in stimulating farms’ agrobiodiversity, but proximity to densely populated areas is a necessary precondition for the development of the short food supply chains needed to stimulate the diversification of organic agriculture.

Circular economy (CE) is increasingly seen as a promising paradigm for transitioning agri-food systems towards more sustainable models of production and consumption, enabling virtuous and regenerative biological metabolisms based on strategies of eco-efficiency and eco-effectiveness. This contribution seeks to provide a theoretical and empirical framework for operationalizing the CE principles into the olive oil supply chain, that plays a central role in the agroecological systems of the Mediterranean region. A scoping literature review has been conducted in order to identify the available pathways so far explored by scholars for reshaping the olive oil supply chain from a circular perspective. The analyzed literature has been charted on the base of the circular pathway examined, and according to the supply chain subsystem(s) to which it refers. Results are discussed highlighting the main issues, the technology readiness level of the available pathways, the prevailing approaches and knowledge gaps. A synthetic evidence map is provided, framing visually the scrutinized pathways into the Ellen MacArthur Foundation’s CE ‘butterfly’ graph. The work is intended to be a valuable baseline for inquiring how circularity can be advanced in the specific supply chain of olive oil, and which are the strategic opportunities, as well as the barriers to overcome, in order to foster the transition.

Abstract Energy production from anaerobic digestion of organic waste and dedicated digestable biomass is a promising climate change mitigation option. Over the last ten years anaerobic digestion has become established in many European countries. The plants have been developed for renewable energy generation, but also to control the emission of odors from zootechnical farms and to stabilize biomass before its agronomic use. In Italy the subsidies available for power generation from biomass have given rise to renewed interest in biogas, creating new opportunities for the agricultural and livestock sectors. Despite of this, in Southern Italy the manure is highly dispersed over a large number of small-size cattle farms, while power generation facilities are affected by scale economies and the aggregation of input biomass is a major logistic, managing, economic and environmental drawback towards the diffusion of such technologies. In this paper, an investment decision methodology for the assessment of optimal size and feedstock mix of biogas power plants fed by cattle manure and energy crops is presented. The methodology is applied to one of the most promising basins of Puglia region, in Southern Italy, represented by the Municipalities of the Local Action Group “ Terra dei Trulli e del Barsento ”, Province of Bari. The main factors influencing the profitability of these investments are assessed, with biogas power plant size ranging between 50 kW and 1 MW, and on the basis of the recently introduced feed-in tariff scheme for such plants (D.M. 6 July 2012). The results show that a high manure recovery rate, the reuse of biogas slurry and the cogeneration options are major key factor for the profitability of the investments.

One of the main dilemmas faced by small-scale farmers’ movements advocating for agroecology in Latin America lies in the trade-offs between the economic opportunities arising from the organic food market expansion, and the political principles at the core of their action. To provide insights on this issue, a survey was performed in Brazil and Chile. Between March 2016 and December 2018, data were collected through direct and participant observation, documentary analysis, and interviews conducted to peasant organizations’ leaders, technicians and policymakers. In Brazil, the research focused on the Movimento dos Trabalhadores Rurais Sem Terra (The Landless Movement); while in Chile, due to the absence of such a national social movement, it considered a wider set of actors, including the Instituto Nacional de Desarrollo Agropecuario (National Institute for Agricultural Development). The results show how social movements are navigating between the mainstreaming pressures of the conventional markets, dominated by the leading agri-food corporations, and the political efforts they have been doing to build civic food markets as alternatives to conventionalization patterns. Finally, we argue that social scientists should better explain the tensions and compromises the social movements go through in order to coordinate different and complementary marketing strategies.

Food is central to human beings and their social life. The growing industrialization of the food system has led to a greater availability of food, along with an increasing risk perception and awareness in consumers. At the same time, there is an increasing resistance from citizens to the dominant model of production and a growing demand for healthy food. As a consequence, an increasing number of social networks have been formed worldwide involving the collaboration between producers and consumers. One of these networks, the Ecovida Agroecology Network, which operates in Southern Brazil, involves farming families, non-governmental organizations, and consumer organizations, together with other social actors. Using a qualitative approach based on participant observation and an analysis of documents, the article examines this network. The theoretical framework used is social innovation, which is commonly recognized as being fundamental in fostering rural development. Results show that Ecovida has instigated innovations that relate to its horizontal and decentralized structure, its participatory certification of organic food, and its dynamic relationship with the markets based on local exchanges and reciprocal relations. Furthermore, such innovation processes have been proven to impact on public sector policies and on the increasing cooperation between the social actors from rural and urban areas.

In recent years, the environmental sustainability of agri-food systems has become a crucial issue. Agri-food firms are increasingly concerned with the implementation of viable environmentally friendly production processes. The environmental impacts of the table grape sector, as well as other fresh and not transformed food products, involve mainly the farming phase rather than the subsequent conditioning, transportation, packaging, and distribution phases. The purpose of this study was to assess the environmental impacts and the economic viability of three table grapes production models (i.e., early harvesting, normal harvesting, and delayed harvesting), based on the Italian tendone system, during the entire life cycle. The environmental impact analysis was performed using the life cycle assessment (LCA) approach, while the economic analysis was performed using the life cycle costing (LCC) approach. The results show that the early and the delayed production models generated the highest environmental burdens, but also the highest economic returns, compared to the normal harvesting production model. The main determinants of the environmental impacts and economic returns are discussed and some practical recommendations are given to improve the sustainability of all the surveyed production models, so to converge public and private interests.
