“…Moreover, the price of their produce normally decreases after harvest and peaks in the lean season, as evident during our FGDs. For this reason, food insecurity and malnutrition increase in the lean season, especially for rural population confirming the literature focused on research areas similar to ours (Brander et al, 2021;Sassi, 2019).…”

“…The empirical literature highlights seasonality and vulnerability as important factors shaping the dynamics of food security in Sub-Saharan Africa (Devereux et al, 2013;Sassi, 2015Sassi, , 2019. The region witnesses substantial seasonal and spatial variation in crop production and household-level food access conditions (Bolarinwa et al, 2020;Brander et al, 2021;Cedrez et al, 2020;Sassi, 2019;Thornton et al, 2009). Consequently, an understanding of both temporal and spatial dimensions of household food security status should be important for better designing the targeting of food security interventions.…”

The increasing complexity of food insecurity, malnutrition, and chronic poverty faced by Sub-Saharan Africa warrants urgent categorisation and tracking of household food security along both temporal and spatial dimensions. This will help to effectively target, monitor and evaluate population-level programs and specific interventions aimed at addressing food insecurity. Traditional longitudinal analysis does not address the dynamics of inter- and intrahousehold heterogeneities within the seasonal and spatial context of household-level food security. This study is the first to overcome such limitations by adopting a multi-group piecewise latent growth curve model in the analysis of the food security situation in a statistically representative sample of 601 households involved in subsistence and cut-flower commercial agriculture, around Lake Naivasha. We considered food security as a latent concept, which manifests as food security outcomes in our primary longitudinal dataset from March 2018 to January 2019. Our analysis highlights the temporal and spatial dynamics of food security and advances new evidence on inter- and intrahousehold heterogeneities in food security across different seasons for the subsistence and commercial farming clusters. These heterogeneities were demonstrated primarily during the hunger season from March to June, and persisted in both the clusters and across months, albeit with different intensities. Moreover, our results indicate the importance of commercial agriculture in achieving food security in the hunger season. Our study suggests the need of a multidisciplinary approach to food security and the introduction of well-coordinated interventions for the development of subsistence and commercial agriculture considering the seasonal and cluster-level specificities.

“…Food systems improvements may not necessarily be costly or technologically advanced. Recent research on combatting losses in Tanzania, mainly for maize, found that the use of inexpensive 100 kg hermetic storage bags could reduce infestation by, and losses through, insects and other pests and mitigate food insecurity by 38% in the lean season for smallholder farmers ( Brander et al 2020 ). In this case, disentangling the effects of the technology itself from the effects of training on adoption of new storage technology needs further work, and illustrates the multisectorality of the food systems challenges which constrain good nutrition and health.…”

Highlights Current agri-nutrition research focuses on micronutrient malnutrition and stunting. The dietary contribution of many essential bioactive food components is understated. Cereals are rich in bioactives such as dietary fibre that have major health benefits. Research should address the full health benefits of cereals like maize and wheat. Agri-nutrition studies should be multidisciplinary and whole food systems-oriented.

“…After the Rwandan genocide of 1994, the country as a whole adopted stronger cultural values such as unity, selflessness, volunteerism and humility which is apparent when one is immersed within the culture and exhibited by way of many of their government policies. 28,29,30 This compassion is often translated to assisting others who are in need through the giving of money, food, household goods, employment opportunities and childcare. When considering this in the context of food security, many participants reported that they gave food away to others, possibly hindering their own household food security status.…”

Objectives In Rwanda, rates of malnutrition remain high in rural areas where residents consume a primarily starch-based, low variety diet. Nutrition-sensitive agricultural interventions using kitchen gardens have been effective in addressing low diet diversity in similar populations. This study’s objective was to develop a kitchen garden and nutrition education intervention aimed at sustainably increasing diet diversity and food security at the household-level. Design A mixed methods community-level study, with a sixteen-week nutrition-sensitive agricultural intervention including nutrition education was conducted. Household diet diversity scores and household hunger scores were calculated at baseline, post-intervention and one-year follow-up. Setting The intervention was conducted in a rural Rwandan community in the Northern Province. Participants Stratified purposeful sampling techniques were used to select women participants representing forty-two households. Results Household diet diversity scores increased over time from pre-intervention to six months post-intervention and one-year post-intervention. The magnitude of the change was similar in all stratified groups (2.3x at 6 months and 2.9x at 1 year). Households whose main source of income was working for other farmers, reported a significantly lower diet diversity score than those households receiving income from sources [t(40) = -2.108, p=0.041]. Among those households not consuming protein and vitamin-A rich food groups at baseline, all reported consuming foods from these food groups post-intervention. There were no significant changes in household hunger scores. Conclusions Collaborative community-based nutrition-sensitive agricultural interventions using kitchen gardens, can increase household diet diversity, which may encourage sustained change in dietary patterns for nutritional adequacy in low-income rural Rwandan populations.
