The proportion of older adults is increasing globally, yet many of them experience food insecurity. Technological innovations, such as increased access to internet- and mobile-based food delivery apps (FDAs), may help mitigate food insecurity. However, this topic has been understudied. This scoping review searched for publications and online technical reports from around the world using interdisciplinary databases like ScienceDirect and internet sources like government websites, respectively. Eligible references were published recently (2019–present) and focused on general technology use, including apps, among older adults (≥50 years) or FDAs for food insecurity or nutritional health generally or specifically among older adults. The search identified 19 studies from 10 countries and extracted relevant information for summary tables. A limited number of studies supported the idea that FDAs can help address food insecurity, but there are important equity considerations for older adults living in rural areas or with constrained physical abilities. Consistently, customized app features and functions increased the intention to use FDAs. In addition, FDAs may have health and environmental impacts, such as food waste and increased access or promotion of ultraprocessed foods. Additional research is needed to elucidate the potential of FDAs to address food insecurity generally and specifically among older adults.

Environmental justice and sustainability have both become major concerns for water resource management, particularly with recent federal emphasis on environmental justice under the Biden administration in the United States. Texas, like many U.S. states, lags behind the federal government in this emphasis. While many localities have made progress in some respects—for example, some major Texas municipalities have included equity and sustainability metrics in their recent climate action plans—others have not. This has left a patchwork of persistent water management and availability issues that are exacerbated by extreme weather and worsening impacts of climate change. We provide a review of many of Texas’s water equity and sustainability challenges, both now and in a more extreme climate future. These include water access, affordability, contamination, flooding, drought, and aging infrastructure. For example, many Texas counties rank highest in the nation for flood risk, including coastal counties with high populations of disadvantaged communities and counties containing populations that live in persistent poverty in the Lower Rio Grande Valley. Additionally, approximately 44,000 Texans, or about 0.4% of the state population, lack access to complete plumbing facilities in their homes. The costs of water infrastructure leaks (estimated at about 51 gallons of water per day statewide) are shared across customers of all income levels, though they place a disproportionate burden on low-income customers. We then assess existing statewide and local policy and planning efforts and gaps in addressing these concerns in Texas. We focus particularly on the role of efforts to incorporate community voice—the ideas, concerns, needs, and expertise of impacted community members, dismantle causes of injustice, and improve equity in spending. If communities are not intentional with future development, new water infrastructure could continue to perpetuate existing harms. Thus, we provide a research agenda and recommendations for addressing some of the policy and planning gaps and persistent environmental justice issues. We aim to help water managers and policy makers identify and dismantle sources of inequity, particularly through including community voice.
