A theoretical essay on hunger in Brazil (2025) applies the Public Policy Cycle Model to the persistent, structural problem of hunger in Brazilian politics, noting that hunger is not unique to Brazil — about two billion people worldwide experience moderate or severe food insecurity — while all Brazilian regions show nutritional deficits tied to inadequate or insufficient food intake. In this context, it frames urban and peri-urban agriculture (AUP) as a social and public-policy tool for promoting food and nutrition security, examining the agenda-setting and formulation stages of AUP policy through discussions from Brazil's National Conferences on Food and Nutrition Security. Noting the 2024 establishment of Brazil's National Urban and Peri-urban Agriculture Policy and its ties to the UN Sustainable Development Goals, the essay concludes that much remains to be done to strengthen AUP as public policy and consolidate its social, economic, and environmental impact, particularly to make it effective for promoting food and nutrition security.

Using an existing hydroponics system in Chicago as a case study, this life cycle assessment (environmental impact via SimaPro, social and economic sustainability via a semi-quantitative approach) compared a hypothetical scaled hydroponics system against a scaled community garden serving the same number of users in the same area. The results show hydroponics systems present greater sustainability challenges than community gardens overall, though a hydroponics system incorporating LED lights was found to be more sustainable than the community garden; the authors call for future research to more accurately assess the differences between the two models.

Drawing on an analysis of recent crises in Brazil—transportation strikes, floods, prolonged droughts, the pandemic, currency fluctuations, and international conflicts—that exposed fragilities in the food supply chain leading to food insecurity, food deserts, and shortage risk, this study proposes urban food self-sufficiency strategies using nationally and internationally recognized urban agriculture techniques. It examined hydroponic cultivation and vertical farms through technical site visits, literature review, and interviews with managers and nutritionists, defining the built and cultivable area needed to guarantee a minimum survival diet for an estimated population, and, given the relevance of energy consumption to final food cost, incorporated solar power installations sized to different demand levels to reduce grid dependence; the plan was conceived initially as an alternative system with potential to evolve into a redundant, mitigating system.

A qualitative, exploratory-descriptive study based on bibliographic and documentary review examines urban agriculture as a socio-environmental alternative to the contradictions of the Green Revolution. Drawing on classic and contemporary national and international literature and reports from multilateral bodies such as the FAO and UN-Habitat, it characterizes the Green Revolution as having raised agricultural productivity while deepening social inequality, homogenizing crops, and causing serious environmental impacts. It positions urban agriculture as valuing production diversity, strengthening community autonomy, and fostering new forms of sociability, concluding that examples across different contexts converge in strengthening food sovereignty, social inclusion, and urban sustainability.

A study in Oaxaca, Mexico, documented the selection process of pitahaya (Hylocereus spp.) in family gardens. It was observed that women establish and care for pitahaya in family gardens, while both men and women are involved in commercial gardens. Women and/or producers select, exchange, propagate, and cultivate pitahaya stems to achieve better prices and profits. The findings suggest that pitahaya can be established alongside other agricultural crops to promote product diversification and provide economic benefits to families.
