This overview, based on the ScienceDirect database, addresses heavy metal (HM) contamination in vegetables from urban and peri-urban areas. It notes that HMs like Cd, Pb, Hg, Cr, and As accumulate to toxic levels in the soil-plant-consumer continuum, causing health damage to consumers and physiological alterations in plants. Leafy and solanaceous vegetables accumulate the most HMs, while cucurbits and legumes are least affected.

Navjot Sangwan, Luca Tasciotti · Agriculture · Sub-Saharan Africa

This cross-country study analyzed household data from nine Sub-Saharan African countries to investigate the impact of urban agriculture (UA) on household food expenditure and dietary diversity. Using an inverse-probability weighted regression adjustment method, the study found that households engaged in UA reduced overall food expenditure and increased spending on protein-rich foods like nuts, legumes, fruits, dairy, meat, and poultry. The impact of UA varied substantially across the food expenditure distribution.

This study assessed the associations between proximity to green and blue spaces and Serious Psychological Distress (SPD) among urban-dwelling older adults in Washington State. The 2011–2019 dataset from the Washington State Behavioral Risk Factor Surveillance System (BRFSS) was utilized to assess SPD among residents aged 65 and over. Approximately 2% of urban-dwelling older adults had SPD. The odds of experiencing SPD were lower among urban-dwelling adults living within half a mile of green or blue spaces compared to those living further than half a mile from such spaces within Washington State.

Rudra Dahal, Kamala Adhikari, Karen Tang · Journal of Community Medicine & Public Health · Canada

This paper discusses how record-high inflation rates and skyrocketing food prices in Canada exacerbate food insecurity, defined as inadequate food access due to financial constraints. Food insecurity is identified as a strong predictor of poor physical and mental health, higher mortality rates for those with chronic conditions, and increased healthcare utilization and costs. The paper suggests a comprehensive approach combining short-term solutions like community gardens and long-term policy interventions to address the root cause of inadequate income.

In Uganda, this study assessed vegetable performance using a non-greenhouse hydroponic system to investigate its potential as a sustainable urban farming technology for enhancing food security. Leafy lettuce (red and green) was grown using non-circulating hydroponics, with soil-based cultivation as a control, and six parameters—plant height, root length, number of leaves, lettuce weight, moisture content, and dry matter—were measured 20 and 40 days after transplanting. Significant differences (P < 0.05) were found between soil and hydroponic cultivation for dry matter content, fresh weight, and root length, but based on the number of leaves, hydroponics showed potential to perform as equally well as conventional farming.
