The historical struggles that Brazil faced to overcome malnutrition coincided with the empowerment of civil society and social movements which played a crucial role in the affirmation of health and food as social rights. After two decades under military dictatorship, Brazil went through a redemocratization process in the 1980s when activism emerged to demand spaces to participate in policy-making regarding the social agenda, including food and nutrition security (FNS). From 1988 onward institutional structures were established: the National Council of FNS (CONSEA) convenes government and civil society sectors to develop and monitor the implementation of policies, systems and actions. Social participation has been at the heart of structural changes achieved since then. Nevertheless, the country faces multiple challenges regarding FNS such as the double burden of disease, increasing use of pesticides and genetically modified seeds, weak regulation of ultra-processed products, and marketing practices that affect the environment, population health, and food sovereignty. This article aims at examining the development of the participatory political system and the role played by Brazilian social movements in the country's policies on FNS, in addition to outlining challenges faced by those policies.

Environmental legislation is increasingly changing its focus from manufacturing-oriented to product-oriented instruments. Compliance with product-related environmental legislation is achieved by the incorporation of environmental requirements into the early phases of the product development process (PDP). Nevertheless, the deployment of product-related environmental legislation into product requirements is still a challenge. This study followed an inductive approach to propose a guideline to support the identification, analysis and deployment of product requirements based on product-related environmental legislation. The guideline is composed of nine steps, clustered into three groups according to their main objective: (A) identification of environmental product-related legislation; (B) identification of legislative topics to be considered for the deployment of requirements; and (C) creation and validation of product requirements. The product requirements deployed are to be considered during the PDP. The guideline was evaluated in an expert consultation in a large manufacturing company, suggesting that it can be used to support the systematization and deployment of product-related environmental requirements.

Medidas regulatórias estão entre as estratégias de promoção da alimentação adequada e saudável preconizadas pela Política Nacional de Alimentação e Nutrição (PNAN). Embora outras ações de promoção da alimentação adequada e saudável tenham avançado no Brasil, essas medidas progridem lentamente. O objetivo do trabalho é identificar e descrever fatores relacionados ao desenvolvimento e à implementação das principais medidas regulatórias de proteção da alimentação adequada e saudável no Brasil nos últimos 20 anos. É um estudo qualitativo documental que avaliou algumas medidas regulatórias de proteção à alimentação adequada e saudável federais, propostas ou em discussão, entre 1999 e 2020. São elas: regulação da publicidade de alimentos; regulação da comercialização de alimentos no ambiente escolar; implantação da rotulagem nutricional frontal obrigatória de alimentos; e tributação de bebidas adoçadas. A maioria das barreiras identificadas foram estratégias de atividade política corporativa protagonizadas pelo setor privado, principalmente, pela indústria de alimentos. Dentre as estratégias de atividade política corporativa utilizadas em diversas etapas dos processos políticos destacam-se: ações judiciais contra a ação do Estado; substituição de políticas sugerindo alternativas voluntárias ou inefetivas; oposição, fragmentação e desestabilização, com busca de apoio da comunidade. No período estudado, nenhuma das medidas foi aprovada. Diante desse cenário, os obstáculos para aprovação das medidas regulatórias de proteção a alimentação adequada e saudável necessitam ser superados no Brasil.

Sustainability and the Right to Food The present work is focused on the relationship between the human right to food, sustainability and the conflicts arising from the realization of this right in current food systems. We seek to understand which aspects are being considered in the specification of this right and how sustainability would be an ethical value and an inherent principle of the human right to food. We propose the following questions as a guide to the research: What is human right to food? What is sustainability? Sustainability is an inherent aspect of the human right to food? Does it occur in the current models of production and consumption? What are the conflicts and impediments to the completion of the human right to food through the prism of sustainability? The methodological approach includes the analysis of the case of production and consumption of genetically modified (GM) foods in contrast with the assumptions adopted in this work. The production model of GM foods is analyzed against the alternative model of agroecology in order to compare the presence of sustainability aspects in both systems. We discuss the role of the consumer as an agent capable of promoting sustainability of food systems, as well as the economic difficulties to exhert this role. From this analysis, we found the existence of public-private conflicts emerging from realization of the human right to food when looking through the prism of sustainability. Before such obstacles, we present mechanisms of enforceability and justiciability of the human right to food. We seek to transversely address themes such as solidarity, ethics in science and in capitalism, and education as challenges to be conquered in order to achieve the full realization of the human right to food from the perspective of sustainability.
