• Analytical framework on climate projection and its illustration of risks to nutritional health in the Solomon Islands (2025) · Frontiers in Sustainable Food Systems · cited 1× · doi

  1 Introduction Climate change, extreme climate events, food production, and human nutrition research are becoming increasingly crucial, as noted by various researchers (Baumgard et al., 2012; Campbell et al., 2018; FAO, 2019; Pieters et al., 2013; Tuomisto et al., 2017; Schnitter and Berry, 2019). Although climate change is one of the biggest threats to the global health crisis, the lack of focus on climate projections and projected impacts on the nutritional content of crops and vegetables, with dietary requirements for human diets remains a gap in the current knowledge

• Reduced meat and dairy consumption improves health, environmental and most nutritional outcomes without increasing diet costs among Scottish adults (2026) · Nature Food · doi

  Shifting diets away from high levels of meat and dairy is increasingly considered an important part of climate mitigation, yet the best pathways for achieving these reductions without compromising nutrition, health or affordability remain unclear.

• Safeguarding diet quality in a changing climate: a scoping review (2026) · Frontiers in Nutrition · doi

  Climate change is reducing crop yields and diminishing nutrient density. Malnutrition, largely driven by poor diets, is the leading global health risk. There is a lack of studies on the impact of climate change on fruits and C4 crops.

• Potential of egusi for food and nutrition security in northern Ghana: gender perspectives and social constructs underpinning cultivation and use (2025) · Frontiers in Sustainable Food Systems · cited 3× · doi

  Climate-induced food insecurities affect egusi production. The study identifies the need for empirical data to inform policy and strengthen coordinated engagements. The communities face challenges in reducing bush burning and mitigating climate change.
