The prevalence and severity of natural hazards pose a serious risk to food systems, undermining their function to provide food security and improved nutrition. The impact of such events is extensive, and the level of damage and recovery significantly depend on ecosystem services, including their own resilience capacity. This paper provides evidence that the role, value, and utilization of local ecosystem services are essential for food system resilience and for food security in parts of the world where high vulnerability and lack of coping capacity exist to combat climate change. Patterns of ecosystem services-based strategies were revealed that can be introduced to cope and adapt to climate-related natural hazards at the smallholder food system level. The study suggests that food system diversification, technological innovations and nature-based practices, and traditional and indigenous knowledge operationalized across the food system components have a potential for sustaining smallholder resilience in the face of natural hazards.

The transition to sustainable agriculture is a critical challenge for the U.S. food system. A sustainable food system must support the production of healthy and nutritious food while ensuring economic sustainability for farmers and ranchers. It should also reduce negative environmental impacts on soil, water, biodiversity, and climate, and promote equitable and inclusive access to land, farming resources, and food. This narrative review synthesizes U.S. social science literature to identify the key factors that support or impede the adoption of sustainable agricultural practices in the U.S. Our analysis reveals seven overarching factors that influence producer decision-making: awareness and knowledge, social factors, psychological factors, technologies and tools, economic factors, implementation capacity, and policies and regulations. The review highlights the critical role of social science in navigating complexity and uncertainty. Key priorities emerging from the literature include developing measurable, outcome-based programs; ensuring credible communication through trusted intermediaries; and designing tailored interventions. The findings demonstrate that initiatives will succeed when they emphasize measurable benefits, address uncertainties, and develop programs that capitalize on identified opportunities while overcoming existing barriers.

The limited resilience of agricultural and food systems has become an agenda in the time of more extreme natural hazards. The impact of such events is extensive, and the level of damage and recovery strongly depends on ecosystem services, including their own resilience capacity. Most of the time, ecosystems themselves can offer mitigation measures based on the benefits people get from nature, including cultivated and wild biomass for nutrition, materials, or energy; pest and disease control; and regulation of baseline flows, among others. The 27th Conference of the Parties to the United Nations Framework Convention on Climate Change, held in Sharm el-Sheikh, Egypt, addressed issues related to crop production, food security, and nutrition. The information garnered from this conference provided impetus for actions that we believe can ensure a future with the resources needed for sustainable development and that support the health and nutrition for all the inhabitants on Earth.

This study explores the uptake and potential application of nature-based solutions (NbS) that are particularly promising for small-scale farmers, ranchers, and food entrepreneurs operating in arid and semi-arid regions. Studying the adoption of NbS by local food entrepreneurs (LFEs), including related strengths and limitations, remains an area of exploration due to their potential to optimize interventions that foster environmental sustainability at the intersection of people, animals, and natural ecosystems (i.e., One Health). A multi-method design was used, including literature review, questionnaires, and semi-structured key informant interviews to assess adaptation needs and NbS among a sample of LFEs located in Southern AZ, USA. The findings revealed that existing NbS have been introduced mostly through learning-by-doing practices that are bounded by economic and technological resource constraints. The paper describes a range of accessible approaches and practices that can be piloted and/or scaled up to enhance local food system resilience and contribute to the overlapping health of people, animals, and natural ecosystems. The priority adaptation pathways for NbS were identified to be funding and financing and the co-creation and sharing of knowledge through peer-to-peer and expert-to-peer approaches. The results suggested that AZ LFEs are likely to adopt NbS based on their capacity to address priority climate-driven issues, revenue generation potential, and seamless augmentation with existing food production and operational activities.

The 28th session of the Conference of the Parties (COP 28) to the UN Framework Convention on Climate Change brought together 85 000 climate stakeholders to leverage solutions and accelerate climate actions in 4 key areas: energy transition; issue of funding and financing of climate actions; emphasis on nature, people’s lives, and livelihoods; and ensuring inclusivity for all. This commentary highlights insights at the intersection of health, climate, and food gained by the author from participating in COP 28 events. The objective is to inform policymakers, researchers, and practitioners on emerging opportunities to scale specific, measurable, achievable, relevant, and time-based (SMART) climate actions that prioritize health and boost the resilience of food and public health systems.
