Household food and packaging waste sit at the intersection of everyday routines and municipal service systems. Equity problems emerge when participation costs such as time, distance, storage space, and digital requirements are unevenly distributed across households. This systematic literature review synthesizes 55 Scopus-indexed journal articles published between 2020 and 2025, screened and reported using PRISMA 2020. We organize the evidence into four themes: equity determinants (gendered household labor, education-related competencies, and digital connectivity), service design mediators (coverage, proximity, pickup reliability, cleanliness, and rule clarity), measurement and bias in household waste quantification (self-report, diaries, weighing, composition audits, and smart sensing), and equity performance of packaging-oriented instruments (pay-as-you-throw pricing, deposit-return systems, extended producer responsibility, and refill or reuse models). Across contexts, equity effects are conditional on access: service reliability and convenience often explain intention-behavior gaps more than attitudes alone. Self-report methods frequently underestimate waste and overstate pro-environmental practices, while high-burden protocols risk excluding time-constrained households and biasing subgroup comparisons. We conclude with an access-first implementation roadmap and an equity-credible evaluation checklist combining affordability safeguards, low-technology participation pathways, and mixed-method measurement designs.

Rising consumption of bottled water and sugar-sweetened beverages poses challenges for health, environmental sustainability, and equity in access to safe drinking water. This systematic review examines interventions promoting a shift from bottled drinks to tap or plain water, focusing on behavioral mechanisms and impacts on health, nutrition, and the environment. Studies reviewed included diverse settings and methodologies, assessing outcomes related to beverage intake and associated indicators. Successful interventions combined infrastructure improvements, such as hydration stations, with education and policy changes favoring tap water. Behavioral responses were influenced by perceptions of safety and taste, while socio-economic and demographic factors affected effectiveness. Interventions generally led to reduced consumption of sugar-sweetened beverages and increased tap-water intake, with evidence of improved health outcomes in high-risk populations. Modelling studies anticipated significant reductions in greenhouse gas emissions and resource use by substituting tap water for bottled beverages. The review concludes that well-designed interventions can foster healthier beverage systems but calls for longer-term assessments that encompass health, environmental, and equity outcomes.

Climate change and land-use/land-cover (LULC) dynamics jointly reshape watershed hydrology and water quality, yet their relative contributions remain difficult to isolate across regions, indicators, and methods. This systematic review synthesizes 28 peer-reviewed studies (2000–2025) that explicitly attribute or partition climate and LULC effects on streamflow, water yield, evapotranspiration, baseflow, and multiple water-quality indicators (e.g., nutrients, sediments, dissolved organic matter, salinity/alkalinity, and contaminant mixtures). Studies were grouped into four synthesis themes: (i) conceptualizations and study designs, (ii) process-based and hybrid modeling frameworks, (iii) statistical and decomposition approaches, and (iv) cross-context patterns and water-quality attribution. Across the evidence base, attribution outcomes are strongly conditioned by methodological choices—especially baseline definition, construction of climate-only and LULC-only counterfactuals, spatial and temporal scale, and the metric used to express contributions (e.g., scenario contrasts, sensitivities, or variance explained). Long-term water-balance responses are often attributed primarily to climate forcing, while water-quality outcomes are more frequently attributed to LULC and direct anthropogenic pressures, with climate acting as a key modulator of transport pathways and exposure. We conclude that robust climate–LULC attribution requires explicit counterfactual design, integrated use of process-based and data-driven frameworks, explicit representation of interactions, and routine uncertainty analysis to support context-sensitive watershed management and climate adaptation.
